Description

Technical Field

[0001] This invention relates to the field of disinfection technology, specifically to a disinfectant supply device and supply method. Background Technology

[0002] Many devices with built-in sealed water pipes or water passages (such as tea makers, coffee makers, ovens, or ice makers) require regular disinfection of their internal pipes and components to meet hygiene standards. However, disinfectants generally have a short shelf life (for example, they are only effective for 24 hours after dissolving in water), thus requiring them to be prepared and used immediately. This necessitates frequent addition of disinfectant, which is cumbersome. Furthermore, adding large quantities of disinfectant at once requires a highly airtight storage environment; otherwise, the disinfectant will become ineffective upon contact with water.

[0003] In addition, managing the use of disinfectants and the number of disinfection cycles after adding disinfectants in batches remains a common technical issue in the equipment disinfection process. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the present invention aims to provide a disinfectant supply device that prepares a plurality of independent disinfection units from disinfectant according to the dosage required for a single disinfection. The supply device includes: a receiving cavity in which at least one of the disinfection units is placed; a first conveying member and a second conveying member, respectively rotatably disposed within the receiving cavity; a first conveying edge disposed on the outer surface of the first conveying member along a first helical direction; and a second conveying edge disposed on the second conveying member along a second helical direction. The first and second helical directions are opposite, and the first and second conveying edges are mirror images of each other within the receiving cavity. During the rotation of the first and second conveyors, at least one limiting space for limiting the disinfection unit is formed by the first and second conveying edges along the length direction of the first and second conveyors. The discharge port is located on the wall of the receiving cavity. When the disinfection unit is sent to the discharge port as the first conveyor and the second conveyor move together, the disinfection unit enters the discharge port and is discharged through the discharge port.

[0005] This application has the following beneficial effects: ① By preparing the disinfectant into several independent disinfection units, and using the rotation of the first and second conveyors to sequentially supply each independent disinfection unit, only the appropriate number of disinfection units needs to be added each time, and each disinfection unit is exactly the dosage used for one disinfection, thus eliminating the problem of disinfectant expiration. Moreover, by first preparing the disinfectant into independent disinfection units and storing them in the containment chamber, and then discharging only one disinfection unit per disinfection, it is easy to isolate each disinfection unit from water, thereby effectively extending the shelf life of the disinfection units in the containment chamber.

[0006] ② By setting the thread directions of the first conveying edge and the second conveying edge to be opposite and mirror symmetrical to each other, at least one movable limiting space is formed by the first conveying edge and the second conveying edge, and there is a certain distance between two adjacent limiting spaces. Since each limiting space can convey one disinfection unit, only one disinfection unit can be sent to the discharge port each time, thus ensuring that only one disinfection unit is discharged each time, which is convenient for counting and controlling the amount of disinfectant.

[0007] ③ This application sets the disinfection unit as an independent dosage unit, which is also conducive to the statistics of the number of disinfection times or frequencies, and facilitates the disinfection management of the equipment.

[0008] Furthermore, the first and second conveyors rotate in opposite directions. Using a cross-section perpendicular to the axial direction of the first and second conveyors as a reference plane, with the direction closer to the top of the device to be disinfected considered upwards and the direction closer to the bottom considered downwards, the first conveyor is located on the left and rotates counter-clockwise, while the second conveyor is located on the right and rotates clockwise. Therefore, as the first and second conveyors rotate, it is ensured that disinfection units falling onto their surfaces remain on their upper surfaces or roll to the left or right from their upper surfaces, without exerting a downward force from between them, thus preventing the disinfection units from being crushed or broken.

[0009] Furthermore, the first and second conveying components rotate synchronously. A first gear is located at the end of the first conveying component, and a second gear is located at the end of the second conveying component. The first and second gears mesh with each other. A positioning point is provided on each of the first and second gears to determine their meshing position. By setting these positioning points, it is possible to ensure that the first and second gears are fully meshed in their initial installation positions, and that their first and second conveying edges work together to form a limiting space for receiving the disinfection unit. This avoids the problem of the disinfection unit getting stuck and unable to be conveyed due to misalignment, reduces the difficulty of device assembly, and also ensures the stability of the feeding process.

[0010] Furthermore, the discharge port is located on the bottom wall of the receiving cavity, and the inner wall dimension of the limiting space is larger than or slightly larger than the outer diameter of the disinfection unit. Therefore, when the disinfection unit is moved above the discharge port by the rotation of the first and second conveyors and under the action of the limiting space, the disinfection unit can fall and be discharged naturally under the action of gravity.

[0011] Furthermore, a baffle gate is provided at the lower end of the discharge port. The baffle gate includes a baffle area for blocking the discharge port and a counterweight area connected to the baffle area. The weight of the counterweight area is greater than the weight of the baffle area. The baffle area is located below the discharge port. Under normal circumstances, the baffle area remains blocked from the discharge port under the action of the counterweight area. When the disinfection unit falls into the baffle area, the sum of the weights of the baffle area and the disinfection unit is greater than the weight of the counterweight area, causing it to rotate away from the discharge port. Therefore, normally, when no disinfection unit falls into the guide area, the guide area is always blocked from the discharge port. After the disinfection unit falls into the baffle area, the baffle gate opens, and the disinfection unit falls out of the receiving cavity. This application cleverly utilizes the gravity of the disinfection unit to open or close the discharge port through the design of the baffle gate.

[0012] Furthermore, a material dropping sensing mechanism and a conveying drive mechanism for driving the first and second conveyors are also provided. The material dropping sensing mechanism sends a signal to the conveying drive mechanism to control the start and stop of the first and second conveyors. After a disinfection unit falls and exits the receiving cavity, the material dropping sensing mechanism sends a stop command to the first and second conveyors, and the disinfection system of the equipment to be disinfected stops discharging the disinfection unit, thus completing the conveying action of one disinfection unit. If it is necessary to continue to add the next disinfection unit, the disinfection command can be restarted.

[0013] Furthermore, the material dropping sensing mechanism includes a material dropping metal sensor switch disposed below the material stop gate. The material dropping metal sensor switch is signal-connected to the conveying drive mechanism. The counterweight area includes a first sensor, and the material dropping metal sensor switch includes a second sensor. After receiving a material dropping command, the material dropping sensing mechanism has two working states: In the first working state, the first and second sensors are connected, and the conveying drive mechanism is in a driving rotation state; in the second working state, the material stop zone flips away from the discharge port, and the first sensor rotates with the counterweight area until it separates from the second sensor, and the conveying drive mechanism is in a stopped state. Thus, each time a material dropping command is received, the second working state of the material dropping sensing mechanism is triggered by the disinfection unit descending to the material stop zone, causing the conveying drive mechanism to stop. This ensures that only one disinfection unit is dropped at a time, preventing multiple disinfection units from dropping simultaneously. Consequently, it is easier to accurately control the material dropping process and quantity of the disinfection units.

[0014] Furthermore, a mounting groove wall for mounting the baffle gate is provided on the bottom surface of the receiving cavity. The mounting groove wall extends away from the receiving cavity, and a pivot shaft is provided on the mounting groove wall. The baffle gate is rotatably mounted on the mounting groove wall via the pivot shaft. The height of the mounting groove wall is greater than the length of the counterweight area along the direction perpendicular to the pivot shaft. Therefore, when the baffle gate is flipped by the gravity of the disinfection unit, causing the counterweight area to rotate upward, it can be ensured that the counterweight area is completely contained within the space enclosed by the mounting groove wall and is not blocked by the mounting groove wall.

[0015] Furthermore, a partition with through holes is provided within the receiving cavity, forming a desiccant chamber for placing the desiccant. By placing desiccant in the desiccant chamber, the disinfected environment within the receiving cavity can be dried, preventing the disinfection unit from being contaminated by moisture and affecting its disinfection effect.

[0016] Furthermore, a baffle plate is provided above the discharge port within the receiving cavity. The distance between the lower surface of the baffle plate and the upper surface of the first or second conveying member is less than the minimum outer diameter of one of the sterilization units. This prevents the sterilization units from accidentally falling out of the discharge port when multiple sterilization units are present in the receiving cavity. The distance between the lower surface of the baffle plate and the bottom of the lower groove of the limiting space below it is greater than the outer diameter of one of the sterilization units. This allows the sterilization units that have passed through the limiting space and been conveyed to the discharge port to fall smoothly into the discharge port. The surface of the baffle plate has a wall that gradually slopes downwards towards the center of the receiving cavity, serving only as a guide for the sterilization pellets and facilitating their stable downward rolling.

[0017] The present invention also provides a method for supplying disinfectant, wherein the disinfectant is prepared into several independent packaging units according to the dosage used for a single disinfection and stored in a receiving cavity. During each disinfection, one of the independent packaging units of disinfectant is discharged from the receiving cavity into the disinfection system and dissolved in water. The receiving cavity is in a closed state at the time when the disinfectant of the independent packaging unit is discharged. Attached Figure Description

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0021] Example 1: See appendix Figure 1-13 This embodiment is a disinfectant supply device. The disinfectant is prepared into several independent disinfection units 4 according to the dosage used for a single disinfection. For example, the disinfectant can be made into spherical, granular, or irregularly shaped forms, such as pellets. Each individual disinfectant granule or pellet disinfection unit 4 is exactly the dosage used for one disinfection. The supply device of the present invention includes a closable receiving cavity 1, a first conveying member 21, a second conveying member 22, and a discharge port 3.

[0022] At least one disinfection unit 4 is placed in the receiving cavity 1. The receiving cavity 1 can be a completely closed cavity or a cavity with a protective cover 16 that can be opened or closed.

[0023] Combined with appendix Figure 4-9As shown, the first conveyor 21 and the second conveyor 22 are rotatably disposed within the receiving cavity 1. A first conveying edge 211 is provided on the outer surface of the first conveyor 21 along a first helical direction, and a second conveying edge 221 is provided on the second conveyor 22 along a second helical direction. The first and second helical directions are opposite to each other. The first and second conveying edges 211 and 221 are mirror images of each other and symmetrically disposed within the receiving cavity 1. During the rotation of the first and second conveyor 21 and the second conveyor 22, at least one limiting space 5 for limiting the sterilization unit 4 is formed by the first and second conveying edges 211 and 221 along the length of the first and second conveyor 22. This limiting space 5 is not fixed at a specific position on the first and second conveyor 21 and the second conveyor 22; rather, it is a temporary and continuously movable space formed by the interaction of the first and second conveyor 21 and the second conveying edges 211 and 221 with the first and second conveyor 22 during their rotation. The limiting space 5 gradually moves the disinfection unit 4 towards the discharge direction as the first conveyor 21 and the second conveyor 22 rotate. The limiting space 5 does not necessarily need to be a space that completely encloses the entire disinfection unit 4; it only needs to ensure that the disinfection unit 4 is blocked or supported by the limiting space 5 and does not fall off the surface of the first conveyor 21 and the second conveyor 22, and that the disinfection unit 4 is gradually conveyed forward as the first conveyor 21 and the second conveyor 22 rotate. Figure 13 As shown, the height of the upper edge of the limiting space 5 can be slightly higher than the disinfection unit.

[0024] In other possible implementations, the limiting space 5 may also be a groove shape slightly larger than the outer dimensions of a portion of the disinfection unit 4, and as the first conveyor 21 and the second conveyor 22 rotate continuously, the limiting space 5 moves continuously along the axial direction of the first conveyor 21 and / or the second conveyor 22 to feed or discharge the disinfection unit 4.

[0025] In some embodiments, a guide groove 18 is provided in the region of the inner bottom wall of the receiving cavity 1 located between the first conveyor 21 and the second conveyor 22, which is arranged along the axial length direction of the first conveyor 21 and the second conveyor 22. Figure 13 Therefore, the disinfection unit moves along the guide groove 18, and at the same time, as the first conveyor 21 and the second conveyor 22 rotate, the limiting space 5 moves along the guide groove 18 toward the discharge port 3, thereby the disinfection unit is conveyed to the discharge port 3 as the limiting space 5 moves.

[0026] The discharge port 3 is located on the wall of the receiving cavity 1. During the movement of the disinfection unit 4 along with the first conveyor 21 and the second conveyor 22, it is sent to the discharge port 3, and the disinfection unit 4 enters the discharge port 3 and is discharged through the discharge port 3.

[0027] This application has the following beneficial effects: ① By preparing the disinfectant into several independent disinfection units 4, and using the rotation of the first conveyor 21 and the second conveyor 22 to sequentially supply each independent disinfection unit 4, only the appropriate number of disinfection units 4 need to be added each time, and each disinfection unit 4 is exactly the dosage used for one disinfection, so there is no problem of disinfectant expiration. Moreover, by preparing the disinfectant into independent disinfection units 4 first, and only adding the required amount of disinfection units each time, it is easy to isolate the unused disinfection units 4 from the water, thus effectively extending the shelf life of the disinfection units 4 in the receiving cavity 1. In this way, a large amount of disinfectant can be added to the receiving cavity at one time, without the need for frequent disinfectant addition operations.

[0028] ② By setting the thread directions of the first conveying edge 211 and the second conveying edge 221 to be opposite and mirror-symmetrical to each other, the first conveying edge 211 and the second conveying edge 221 can form at least one movable limiting space 5 on the outer surface of the first conveying member 21 and the second conveying member 22, and two adjacent limiting spaces 5 have a certain distance along the axial direction of the first conveying member 21 or the second conveying member 22. Therefore, after each limiting space 5 closest to the discharge port 3 sends a disinfection unit 4 into the discharge port 3, the next disinfection unit still has a certain distance from the discharge port 3, thereby realizing that only one disinfection unit 4 is dropped at a time, which is convenient for counting and controlling the amount of disinfectant.

[0029] ③ This application sets the disinfection unit 4 as an independent dosage unit, which is also conducive to the statistics of the number of disinfection times or frequencies, and facilitates the disinfection management of the equipment.

[0030] In some embodiments, a discharge pipe 6 (attached) connected to the discharge port 3 is also included. Figure 8 The disinfection unit 4 slides down the discharge pipe 6 into the water tank 7 to dissolve, and then passes through the disinfection circulation system to disinfect the internal pipelines of the equipment to be disinfected. The discharge pipe 6 has a guide pipe area 61 that gradually slopes downwards. One end of the guide pipe area 61 is connected to the discharge port 3, and the other end faces the water tank 7.

[0031] In some embodiments, the first conveyor 21 and the second conveyor 22 rotate in opposite directions. Using a cross-section perpendicular to the axial direction of the first conveyor 21 and the second conveyor 22 as a reference plane, when facing the reference plane, the direction closer to the top of the device to be disinfected is considered upward, and the direction closer to the bottom of the device to be disinfected is considered downward. The first conveyor is located on the left and rotates counterclockwise, while the second conveyor is located on the right and rotates clockwise (see attached diagram). Figure 8 and 12 Therefore, it can be ensured that the disinfection unit 4 rolls from the upper surface of the first conveyor 21 and the second conveyor 22 to the left and right sides as the first conveyor 21 and the second conveyor 22 rotate, thus avoiding crushing of the disinfection unit.

[0032] In some embodiments, the first conveyor 21 and the second conveyor 22 rotate synchronously. A first gear 81 is provided at the end of the first conveyor 21, and a second gear 82 is provided at the end of the second conveyor 22. The first gear 81 and the second gear 82 mesh with each other. A positioning point 811 is provided on the first gear 81 and the second gear 82 respectively for positioning the meshing position of the first gear 81 and the second gear 82. Figure 8 By setting the positioning point 811, the first gear 81 and the second gear 82 can be fully meshed in their initial installation positions, and the first conveying edge 211 and the second conveying edge 221 on their surfaces can cooperate to form a limiting space 5 for receiving the disinfection unit 4. In actual installation, even if the first gear 81 and the second gear 82 are meshed, it cannot be guaranteed that the first conveying edge 211 and the second conveying edge 221 will cooperate to form the limiting space 5 on the upper side of the first conveyor 21 and the second conveyor 22. For example, if there is misalignment between the first conveying edge 211 and the second conveying edge 221, a limiting space 5 that can stably receive the disinfection unit 4 cannot be formed, and the disinfection unit 4 will be stuck between the two conveyors, preventing normal conveying of the disinfection unit 4. By setting positioning point 811, the relative positions of the first conveyor 21 and the second conveyor 22 can be quickly calibrated during installation, ensuring that the first conveyor edge 211 and the second conveyor edge 221 can accurately cooperate to form a stable limiting space 5 during each assembly. This avoids the problem of the disinfection unit 4 being stuck and unable to be conveyed due to misalignment during installation, reduces the difficulty of device assembly, and also ensures the stability of the material supply process.

[0033] In some embodiments, the sides of the first conveying edge 211 and the second conveying edge 221 that are close to each other are arc-shaped surfaces. The two arc-shaped surfaces can be used together to form a limiting space 5, which is just right to fit the shape of the spherical or quasi-spherical disinfection unit 4. This can better limit and support the disinfection unit 4 and prevent the disinfection unit 4 from shaking and falling during the conveying process.

[0034] In some embodiments, the discharge port 3 is located on the bottom wall of the receiving cavity 1, and the inner wall dimension of the limiting space 5 is larger than or slightly larger than the outer diameter dimension of the disinfection unit 4. Therefore, when the disinfection unit 4 is moved above the discharge port 3 as the first conveyor 21 and the second conveyor 22 rotate and under the action of the limiting space 5, the disinfection unit 4 can fall and be discharged naturally under the action of gravity.

[0035] The first conveyor 21 and the second conveyor 22 are positioned close to the bottom wall of the receiving cavity 1, but a certain gap must be maintained between them and the bottom wall. Therefore, the bottom wall can provide a certain support for the disinfection unit 4, allowing it to be pushed forward smoothly.

[0036] In other possible implementations, the inner wall size of the limiting space 5 can be set to be smaller than or slightly smaller than the outer diameter of the sterilization unit 4. Correspondingly, the discharge port 3 is located on the side wall of the receiving cavity 1, so that the sterilization unit 4 is always above the first conveyor 21 and the second conveyor 22 along with the limiting space 5. Therefore, when the sterilization unit 4 is pushed to the discharge port 3, it is discharged from the discharge port 3 located on the side wall.

[0037] In some embodiments, a baffle gate 9 is also provided at the lower end of the discharge port 3. The baffle gate 9 includes a baffle area 91 for blocking the discharge port 3 and a counterweight area 92 connected to the baffle area 91. The weight of the counterweight area 92 is greater than the weight of the baffle area 91. The baffle area 91 is positioned directly below the discharge port 3. Under normal circumstances, the baffle area 91 remains in a blocked state of the discharge port 3 under the action of the counterweight area 92. When the disinfection unit 4 falls into the baffle area 91, the sum of the weights of the baffle area 91 and the disinfection unit 4 is greater than the weight of the counterweight area 92. The baffle area 91 rotates away from the discharge port 3, thereby opening the baffle gate 9 and allowing the disinfection unit 4 to be discharged. Therefore, under normal circumstances, when no disinfection unit 4 falls into the material guiding area, the material guiding area is always in a blocked state of the discharge port 3. After the disinfection unit 4 falls into the material blocking area 91, the material blocking door 9 opens and the disinfection unit 4 falls out of the receiving cavity 1. This application cleverly utilizes the gravity of the disinfection unit 4 to open or close the discharge port 3 through the structural design of the material blocking door 9.

[0038] In some embodiments, a material dropping sensing mechanism and a conveying drive mechanism 10 for driving the first conveyor 21 and the second conveyor 22 are also provided. The material dropping sensing mechanism sends a signal to the conveying drive mechanism 10 to control the start and stop of the first conveyor 21 and the second conveyor 22. After a disinfection unit 4 falls and exits the receiving cavity 1, the material dropping sensing mechanism sends a stop rotation command to the conveying drive mechanism 10, and the disinfection system of the equipment stops the action of discharging the disinfection unit 4, thus completing the conveying action of one disinfection unit 4. If it is necessary to continue to put in the next disinfection unit 4, the disinfection command can be restarted again.

[0039] In some embodiments, the material discharge sensing mechanism includes a material discharge metal sensing switch 11 disposed below the material stop gate 9, and the material discharge metal sensing switch 11 is signal-connected to the conveying drive mechanism 10. The counterweight area 92 includes a first sensing element 921, and the material discharge metal sensing switch 11 includes a second sensing element 111 (see Appendix). Figure 11 After receiving a material discharge command, the material discharge sensing mechanism operates in two states: In the first state (i.e., the switch is closed), no disinfection unit 4 enters the discharge port 3, the first sensor 921 and the second sensor 111 are connected, the conveying drive mechanism 10 is in a driving rotation state, and the first conveyor 21 and the second conveyor 22 maintain rotation to convey the disinfection unit to the discharge port 3; In the second state, one disinfection unit 4 enters the discharge port 3 and falls into the blocking area 91. At this time, under the gravity of the disinfection unit 4, the blocking area 91 flips downward away from the discharge port 3, and the first sensor 921 rotates with the counterweight area 92 until it separates from the second sensor 111, and the conveying drive mechanism 10 is stopped. Therefore, after receiving a material discharge command, it ensures that only one disinfection unit is discharged each time, preventing multiple disinfection units from being discharged simultaneously, thus facilitating accurate control of the material discharge process and quantity.

[0040] In some implementations, the counterweight area 92 itself can be used as the first sensing element 921, or a corresponding sensing structure can be provided on the side of the counterweight area 92 near the second sensing element 111.

[0041] In some embodiments, a mounting groove wall 12 for mounting the baffle gate 9 is also provided on the bottom side surface of the receiving cavity 1 (see attached diagram). Figure 10The mounting groove wall 12 extends away from the receiving cavity 1. A pivot shaft 121 is provided on the mounting groove wall 12. Correspondingly, the pivot shaft 121 divides the material gate 9 into a counterweight area 92 and a material blocking area 91. The counterweight area 92 and the material blocking area 91 are located on both sides of the pivot shaft 121. The material gate 9 is rotatably mounted on the mounting groove wall 12 via the pivot shaft 121. The height of the mounting groove wall 12 is greater than the length of the counterweight area 92 in the direction perpendicular to the pivot shaft 121. Therefore, when the material gate 9 is flipped by the gravity of the disinfection unit 4, causing the counterweight area 92 to rotate upward, it can be ensured that the counterweight area 92 is completely contained within the mounting groove wall 12 and is not blocked by the mounting groove wall 12.

[0042] In some embodiments, the discharge port 3 can be extended to the mounting groove wall 12 via a discharge pipe 19. Figure 10 Within the space formed, to ensure that the material blocking area 91 can form a good sealing effect on the lower end of the discharge pipe.

[0043] In some embodiments, a partition 13 with a through hole 131 is also provided inside the receiving cavity 1. Figure 9 The partition 13 forms a desiccant chamber 14 for placing the desiccant 141. By placing the desiccant in the desiccant chamber 14, the environment of the disinfection unit 4 inside the housing 1 can be dried. This prevents the disinfection unit 4 from being contaminated by moisture, which would affect its disinfection effect.

[0044] In some embodiments, a baffle plate 15 is also provided above the discharge port 3 within the receiving cavity 1. Figure 9 The distance between the lower surface of the baffle plate 15 and the upper surface of the first conveyor 21 or the second conveyor 22 is less than the minimum outer diameter of a disinfection unit 4. Therefore, when multiple disinfection units 4 are contained in the accommodating cavity 1, the disinfection unit 4 is prevented from accidentally falling out through the discharge port 3. Only when the limiting space 5 moves to the discharge port 3 can the discharge of a single disinfection unit 4 be ensured, and only one disinfection unit 4 can be discharged at a time. Since the limiting space 5 is not continuously generated on the upper surface of the first conveyor 21 or the second conveyor 22, i.e., there is a certain distance between the two limiting spaces 5, it also ensures that only one disinfection unit 4 is discharged at a time. The distance between the lower surface of the baffle plate 15 and the bottom of the lower groove of the limiting space 5 below it is greater than the outer diameter of a disinfection unit 4. Therefore, the disinfection unit 4, after passing through the limiting space 5 and being conveyed to the discharge port 3, can smoothly fall into the discharge port 3. The side surface of the baffle plate 15 is provided with a wall that gradually slopes from top to bottom toward the center of the receiving cavity 1, so as to guide the disinfection pellets and facilitate the stable downward rolling of the disinfection unit 4.

[0045] In other possible implementations, a protective housing 17 is also provided on the outside of the conveying drive mechanism 10.

[0046] In some embodiments, a mounting plate is also provided on the outer wall of the receiving cavity 1. The mounting plate protrudes towards the center of the receiving cavity 1 and has mounting holes for mounting the first gear 81 and the second gear 82.

[0047] Example 2: This embodiment describes a method for supplying disinfectant. The disinfectant is prepared into several independently packaged units according to the dosage required for a single disinfection and stored in a receiving cavity 1. During each disinfection cycle, one independently packaged unit of disinfectant is discharged from the receiving cavity 1 into the disinfection system and dissolves in water. The receiving cavity 1 remains closed during the time the independently packaged unit of disinfectant is discharged, thus preventing contact between the disinfectant and water. By pre-preparing the disinfectant into independent units and discharging only one unit at a time, this application achieves precise control over the amount of disinfectant used, avoiding problems of over- or under-dispensing. It also ensures that unused disinfectant remains in a closed, dry receiving cavity, preventing contamination by water systems or moisture in the storage environment, effectively extending the shelf life of the disinfectant and reducing frequent replenishment operations. Simultaneously, it ensures stable and controllable disinfection results for each cycle.

[0048] In some embodiments, the feeding method of the present invention specifically includes: conveying the independent disinfection units stacked in the receiving cavity one by one to the discharge port through a conveying mechanism. The conveying mechanism includes a first conveying member 21 and a second conveying member 22 with opposite rotation directions. A first conveying edge 211 is provided on the outer surface of the first conveying member 21 along a first spiral direction, and a second conveying edge 221 is provided on the second conveying member 22 along a second spiral direction.
