Detailed Implementation

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0025] refer to Figures 1-2 As shown, a cap structure for a spray bottle includes a bottle body 1 and a nozzle 2. The bottle body 1 contains a liquid medicine that can be released in a mist form. The nozzle 2 can be manually pumped out by pressing the manual pump on it, and sprayed out through the internal flow channel 202 at the nozzle opening 201 on the nozzle 2.

[0026] refer to Figures 2-6 As shown, a first cover 3 and a second cover 4 are sequentially connected above the nozzle 2. Inside the first cover 3 and the second cover 4 are a cleaning rod 5 for cleaning the internal flow channel 202 and a scrubbing block 4042 for cleaning the nozzle opening 201. Opening the second cover 4 allows direct use of the scrubbing block 4042 to clean the nozzle opening 201. At this time, the cleaning rod 5 is hidden inside the second cover 4. When the cleaning rod 5 needs to be used, the upper surface of the second cover 4 can be manually pressed to push out the cleaning rod 5 and clean the internal flow channel 202.

[0027] refer to Figures 1-4 As shown, a first cover 3 is fitted onto the nozzle 2, and a second cover 4 is fitted onto the first cover 3. An opening 301 is provided at the connection between the first cover 3 and the second cover 4. The first cover 3 and the second cover 4 can be separated by gently pushing the opening 301 with a finger, or the second cover 4 can be manually pulled off the first cover 3 to achieve separation. Multiple raised ribs 406 are provided at the connection between the second cover 4 and the first cover 3 to strengthen the connection and prevent accidental detachment.

[0028] refer to Figures 5-6 As shown, the pressing assembly includes a pressing cover 401 and a spring 403. The pressing cover 401 includes an upper cover and a lower connecting sleeve fixedly connected to the cover. The spring 403 is a compression spring, which is sleeved on the connecting sleeve on the pressing cover 401. One end of the spring 403 is fixedly connected to the pressing cover 401, and the other end of the spring 403 abuts against the connecting cover 404. A retaining ring 402 is provided on the upper end face of the second cover 4. The retaining ring 402 cooperates with the pressing cover 401 to limit the pressing cover 401. When the pressing cover 401 is in the limited state, the upper end face of the pressing cover 401 is on the same plane as the upper end face of the second cover 4. When the pressing cover 401 is pressed down, the pressing cover 401 causes the spring 403 to compress. After the pressing cover 401 is stopped, the spring 403 causes the pressing cover 401 to return to its original position. When the pressing cover 401 is pushed by the spring 403 to the position where it contacts the retaining ring 402, the pressing cover 401 is limited by the retaining ring 402.

[0029] refer to Figures 3-6 As shown, a partition plate 405 is provided on the lower end face of the second cover 4. The partition plate 405 is used to install the connecting cover 404 and also serves to separate it from the nozzle 2 inside the first cover 3 below. A threaded hole is provided in the middle of the partition plate 405. The partition plate 405 cooperates with the connecting cover 404. The connecting cover 404 is provided with a thread 4043. The connecting cover 404 is threadedly connected to the partition plate 405. The connecting cover 404 can be removed from the partition plate 405.

[0030] One end of the cleaning rod 5 is fixedly connected to the inside of the pressing cover 401. A through hole 501 is provided inside the connecting cover 404, penetrating the cover and engaging with the cleaning rod 5. When the pressing cover 401 is not pressed, the lower end of the cleaning rod 5 is retracted within the connecting cover 404. When the pressing cover 401 is pressed, the downward movement of the pressing cover 401 causes the fixedly connected cleaning rod 5 to move downwards. The lower end of the cleaning rod 5 penetrates the connecting cover 404 below the pressing cover 401 and extends out from below the connecting cover 404. When the pressing cover 401 is stopped, the spring 403 causes the pressing cover 401 and the cleaning rod 5 to return to their original position, and the cleaning rod 5 retracts back into the connecting cover 404.

[0031] refer to Figures 2-6 As shown, the nozzle 2 is provided with a nozzle opening 201 and an internal flow channel 202. The internal flow channel 202 cooperates with the cleaning rod 5. The cleaning rod 5 is provided with a short brush. When the cleaning rod 5 is inserted into the internal flow channel 202, the short brush on the cleaning rod 5 is rotated to clear the internal flow channel 202 and to remove the blockage when the cleaning rod 5 is pulled out.

[0032] The connecting cover 404 houses a cleaning block 4041 and a scrubbing block 4042. The cleaning block 4041, made of sponge, engages with the cleaning rod 5. As the cleaning rod 5 extends and retracts, the cleaning block 4041 rubs against it, cleaning the short bristles on its surface. The scrubbing block 4042 engages with the nozzle 201. Its radius is slightly smaller than the nozzle 201. Made of hard sponge, the scrubbing block 4042 can be held by the second cover 4 and rotated on the surface of the nozzle 201 to remove dirt. Both the cleaning block 4041 and scrubbing block 4042 are replaceable. Using tweezers, reused cleaning blocks 4041 and 4042 can be removed and replaced with new ones.

[0033] In practical use, when you want to use the nozzle 2 to spray medicine, you can manually pull out the first cover 3 and press the nozzle 2. If the nozzle 2 becomes dirty and clogged after repeated use, you can use your fingers to lift the second cover 4 from the opening 301 or manually pull out the second cover 4 to separate the first cover 3 and the second cover 4. After pulling out the second cover 4, hold the second cover 4 and align the cleaning block 4042 under the second cover 4 with the nozzle 201, press it against the nozzle 201 and rotate the second cover 4 to clean the surface of the nozzle 201 with the cleaning block 4042.

[0034] To further clean the interior of the internal flow channel 202, manually press the press cover 401 downwards to push the cleaning rod 5 with a short brush out from under the second cover 4. Insert the cleaning rod 5 into the blocked internal flow channel 202 and clean the interior of the internal flow channel 202 back and forth. Use the short brush on the cleaning rod 5 to sweep out the blockage. Press the nozzle 2 again until the liquid is pumped out normally to complete the cleaning of the internal flow channel 202 and the nozzle 201.

[0035] The cleaning block 4041 inside the connecting cover 404 can rub and clean the passing cleaning rod 5, cleaning the short bristles on the cleaning rod 5. The cleaning block 4041 and scrubbing block 4042 inside the connecting cover 404 can be replaced using tweezers. To replace the cleaning rod 5, the connecting cover 404 can be manually rotated and removed, the cleaning rod 5 can be pulled out from inside the pressing cover 401, a new cleaning rod 5 can be reinserted, and the cleaning rod 5 can be passed through the connecting cover 404. Then the connecting cover 404 can be rotated and tightened.

[0036] Compared with the prior art, the beneficial effect of this utility model is that a nozzle cleaning structure is installed inside the cap of the spray bottle. By opening the cap, the nozzle that is blocked or dirty can be unblocked and cleaned, so that the spray bottle with blocked nozzle can continue to be used.
