DETAILED DESCRIPTION
[0021] The following is combined with Figure 1-3 This application is described in further detail.
[0022] The present application embodiment discloses a water tank sterilization module of a sweeping robot containing slow-release antibacterial particles. Figure 1 The water tank sterilization module of a sweeping robot containing slow-release antibacterial particles includes a box body 1 for installation in a water tank. The cross-section of the box body 1 is a rectangular ring. In other embodiments, the cross-section of the box body 1 can be designed as a circular ring, etc. according to actual installation conditions.
[0023] Reference Figure 1 and Figure 2 , a water inlet hole 2 is provided on the outer wall of the box body 1, and the water inlet hole 2 is connected to the inside of the box body 1. A plurality of water-permeable partition plates 3 are fixed in the box body 1. The water-permeable partition plates 3 are annular, and the water-permeable partition plates 3 are arranged concentrically with the box body 1. The plurality of water-permeable partition plates 3 are arranged in sequence along the direction close to the center of the box body 1, wherein the water-permeable partition plates 3 are made of porous materials; the water-permeable partition plates 3 divide the inside of the box body 1 into a plurality of chambers 4, and the cross section of the chamber 4 is a rectangular ring; the chamber 4 of the outermost circle is connected to the water tank through the water inlet hole 2, and the water in the outer circle chamber 4 can flow into the inner circle chamber 4 through the water-permeable partition plates 3, and antibacterial particles 5 are placed in each chamber 4, and the water permeability of the water-permeable partition plates 3 is less than the water permeability of the outer wall of the box body 1. In the embodiment of the present application, two water-permeable partition plates 3 are provided, and the inside of the box body 1 is divided into three chambers 4. In other embodiments, the number of water-permeable partition plates 3 can be set according to the size of the box body 1.
[0024] Reference Figure 1 and Figure 2 A layer of microporous filter membrane can be provided on the outer wall of the box body 1 to prevent the antibacterial particles 5 from falling out of the box body 1.
[0025] When in use, the antibacterial particles 5 are loaded into different chambers 4. Since the chambers 4 in the outermost circle are connected to the water tank through the water inlet hole 2, the antibacterial particles 5 can be effectively released. The chambers 4 gradually approaching the center of the box body 1 reduce the amount of molecules entering and leaving under the action of the permeable partition plate 3, which helps to slow down the release rate of the antibacterial particles 5 in the corresponding chamber 4, achieve long-term sustained release of the antibacterial particles 5, help make the antibacterial effect more lasting, extend the replacement cycle of the antibacterial particles 5, reduce the number of user operations to a certain extent, and are simple and convenient.
[0026] Reference Figure 2The antibacterial particles 5 in the chamber 4 are slow-release antibacterial particles, and the slow-release rates of the antibacterial particles 5 in the multiple chambers 4 are gradually slowed down in the direction close to the center of the box body 1. Antibacterial particles 5 with different slow-release rates are placed in different chambers 4, so that the drug release rate of the antibacterial particles 5 in the multiple chambers 4 close to the center of the box body 1 is gradually slowed down, further achieving long-term antibacterial effect, extending the replacement cycle of the antibacterial particles 5, reducing the number of user operations to a certain extent, and being simple and convenient.
[0027] Reference Figure 2 The antibacterial particles 5 in the chamber 4 on the side away from the outer wall of the box body 1 are all coated with a degradable film 6. Specifically, except for the antibacterial particles 5 in the outermost chamber 4, the antibacterial particles 5 in other chambers 4 are all coated with a degradable film 6, and the thickness of the degradable film 6 on the antibacterial particles 5 in multiple chambers 4 increases in the direction close to the center of the box body 1. The degradable film 6 is one of a polylactic acid film, a polyhydroxyalkanoate film, and a natural polymer material film, which is not limited here.
[0028] During use, the antibacterial particles 5 in the inner circle chamber 4 are not easy to release their medicinal effects under the coating of the degradable film 6. As the use time increases, the degradable film 6 gradually degrades into non-toxic and harmless components, and then the antibacterial particles 5 gradually exert their medicinal effects, thereby extending the time for the medicinal effects to take effect and achieving sustained release in different chambers 4 in batches, which helps to make the antibacterial effect more lasting, extend the replacement cycle of the antibacterial particles 5, and reduce the number of operations by the user.
[0029] Reference Figure 2 and Figure 3 The top wall of the box body 1 is provided with an opening 7, the chamber 4 is connected with the opening 7, a box cover 8 for opening and closing the opening 7 is clamped on the box body 1, and when the box cover 8 closes the opening 7, the box cover 8 abuts against the water-permeable partition plate 3; a lock core 9 is slidably penetrated in the opposite sides of the box cover 8, and the sliding direction of the lock core 9 is perpendicular to the depth direction of the box body 1, and a lock groove 10 for plugging and cooperating with the lock core 9 is provided on the inner wall of the box body 1, and the end of the lock core 9 away from the box cover 8 is an arc surface, and the side of the arc surface away from the box cover 8 is inclined upward, and the arc surface is used to slide and abut against the upper edge of the box body 1, and the end of the lock core 9 close to the box cover 8 is fixed An operating block 14 is provided, and the longitudinal section of the operating block 14 is T-shaped. The operating block 14 is slidably arranged in the box cover 8. An operating groove 15 for slidingly cooperating with the operating block 14 is opened on the box cover 8. The operating groove 15 runs through the upper surface of the box cover 8. A spring 11 is fixed between the inner wall of the operating groove 15 and the operating block 14 for pulling the lock cylinder 9 to slide toward the direction close to the lock groove 10. One end of the spring 11 is fixed to a side of the operating block 14 close to the lock groove 10, and the other end is fixed to a side of the operating groove 15 close to the lock groove 10. The extension direction of the spring 11 is parallel to the sliding direction of the lock cylinder 9.
[0030] When it is necessary to open the box cover 8, insert a finger into the operating slot 15 and slide the operating block 14 in the direction away from the lock slot 10. The operating block 14 drives the lock core 9 away from the corresponding lock slot 10, stretching the spring 11, thereby disengaging the lock core 9 from the lock slot 10, and the box cover 8 can be removed from the box body 1, which is convenient for replacing new antibacterial particles 5; when it is necessary to close the box body 1, align the lock core 9 with the corresponding lock slot 10, move the box cover 8 downward, so that the arc surface of the lock core 9 and the upper edge of the box body 1 slide relative to each other, as the box cover 8 continues to move downward, the lock core 9 extends into the box cover 8 under abutment, stretching the spring 11, and when the box cover 8 moves to the point where the lock core 9 is aligned with the lock slot 10, the stretched spring 11 pulls the lock core 9 to slide in the direction away from the box cover 8 and extends into the lock slot 10, thereby realizing the snap-fit installation of the box cover 8 and the box body 1.
[0031] Reference Figure 2 A scraper 12 is slidably arranged in the chamber 4, the outer wall of the scraper 12 abuts against the inner wall of the corresponding chamber 4, the sliding direction of the scraper 12 is parallel to the depth direction of the box body 1, and a transmission member is arranged on the box cover 8 for driving multiple scrapers 12 to slide when the box cover 8 is separated from the box body 1.
[0032] Reference Figure 2 In order to facilitate the sliding of multiple scrapers 12 when the box cover 8 is separated from the box body 1, the transmission member includes a connecting rod 13, and the connecting rod 13 corresponds to the scraper 12. Specifically, each scraper 12 corresponds to two connecting rods 13, one end of the connecting rod 13 is fixed to the bottom wall of the box cover 8, and the other end is fixed to the corresponding scraper 12.
[0033] When the box cover 8 is detached from the box body 1, the box cover 8 moves up in a direction away from the box body 1, and the box cover 8 drives the corresponding scraper 12 to move up through the connecting rod 13, so that the scraper 12 scrapes the inner wall of the corresponding chamber 4, and removes the impurities after degradation of the degradable film 6 and other impurities out of the corresponding chamber 4, thereby cleaning the chamber 4.
[0034] The implementation principle of the embodiment of the present application is: when in use, insert a finger into the operating groove 15, slide the operating block 14 in the direction away from the lock groove 10, the operating block 14 drives the lock core 9 away from the corresponding lock groove 10, so that the lock core 9 is disengaged from the lock groove 10, move the box cover 8 up, open the opening 7, and the scraper 12 is still located in the corresponding chamber 4; the antibacterial particles 5 are loaded into different chambers 4, so that the outermost chamber 4 is loaded with antibacterial particles 5 not coated with the degradable film 6, and the thickness of the degradable film 6 on the antibacterial particles 5 in the remaining chambers 4 increases successively along the direction close to the center of the box body 1, and at this time the antibacterial particles 5 are located on the corresponding scraper 12.
[0035] Then move the box cover 8 downward to make the curved surface of the lock core 9 slide relative to the upper edge of the box body 1. As the box cover 8 continues to move downward, the lock core 9 extends into the box cover 8 under abutment, until the box cover 8 moves to the point where the lock core 9 is aligned with the lock slot 10. The stretched spring 11 pulls the lock core 9 to slide away from the box cover 8 and extend into the lock slot 10, so that the box cover 8 and the box body 1 are snap-fitted and installed, and then the box body 1 is installed at the corresponding position in the water tank of the sweeping robot.
[0036] Since the chamber 4 in the outermost circle is connected to the water tank through the water inlet hole 2, the antibacterial particles 5 in the corresponding chamber 4 can be effectively and quickly released. The multiple chambers 4 along the center direction close to the box body 1, under the action of the permeable partition plate 3 and the degradable membrane 6, help to slow down the release rate of the antibacterial particles 5, achieve long-term sustained release of the antibacterial particles 5, make the antibacterial effect more lasting to a certain extent, extend the replacement cycle of the antibacterial particles 5, reduce the number of operations of the user, and are simple and convenient.
[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
