Obviously, the embodiments described are only 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figures 1 to 5A deodorization system for a public toilet includes a door frame 1. The front of the door frame 1 is movably connected to several door bodies 2 by hinges. The several door bodies 2 are equidistantly distributed. The back of the door body 2 is rotatably connected to a card plate 3 through a damping shaft. The front of the door frame 1 is fixedly connected to several storage boxes 4. The number of storage boxes 4 is the same as the number of door bodies 2. The bottom of the side wall of the storage box 4 is connected to a first one-way valve 5. The first one-way valve 5 can inject deodorant into the storage box 4. The bottom of one side of the storage box 4 is connected to a connecting pipe 6. A one-way valve is installed in the connecting pipe 6, so that the liquid and gas inside the storage box 4 can be discharged, and the outside air will not be sucked in through the connecting pipe 6. The top of the side wall of the storage box 4 is connected to a second one-way valve 17. One end of the connecting pipe 6 is rotatably connected to an atomizing nozzle 7. The atomizing nozzle 7 can spray atomized deodorant, and the interior of the storage box 4 is slidably connected to a spraying mechanism.

[0025] The spraying mechanism includes a piston 801, the outer side of the piston 801 is slidably connected to the inner wall of the storage box 4, the bottom of the piston 801 passes through the bottom of the storage box 4, the bottom of the piston 801 is fixedly connected to a connecting rod 802, one side of the connecting rod 802 is fixedly connected to a sliding plate 803, and the sliding plate 803 is slidably connected to one side of the door frame 1.

[0026] The top of the piston 801 is fixedly connected to a tension spring 804 , one end of which is fixedly connected to the top of the inner wall of the storage box 4 , the top of the inner wall of the storage box 4 is fixedly connected to a baffle 805 , and the bottom of the baffle 805 contacts the piston 801 .

[0027] The working principle of this embodiment is as follows: when an outsider uses the toilet, he will open the door body 2, then close the door body 2 and the door frame 1, and then rotate the card plate 3 to make the card plate 3 fit with the door frame 1, and then lock the door body 2. In the process of locking the door body 2, due to the clockwise rotation of the card plate 3, the sliding plate 803 is pushed downward. After the sliding plate 803 moves downward, it drives the connecting rod 802 to move downward. The connecting rod 802 drives the piston 801 to move downward, so that the piston 801 pushes the deodorant in the storage box 4 to be discharged through the connecting pipe 6. Subsequently, the deodorant is atomized and sprayed by the atomizing nozzle 7 after passing through the connecting pipe 6, and then sprayed into the air on the front side of the door frame 1, thereby decomposing and neutralizing the odor in the air, and the deodorant is sprayed during the process of using the toilet. The deodorant can be sprayed multiple times when multiple people use the toilet. Compared with manual single spraying of deodorant, it is more targeted, can well eliminate the odor in the air, and improve the user experience;

[0028] After using the toilet, the card plate 3 rotates counterclockwise to reset, and the door body 2 can be opened at this time. The piston 801 moves upward under the tension of the tension spring 804, and in the process of the piston 801 moving upward, gas will be sucked in from the outside through the second one-way valve 17, so that the next time the piston 801 moves downward, the deodorant can be atomized and sprayed out again through the inhaled gas.

[0029] Example 2

[0030] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1 to 5 The outer side of the atomizing nozzle 7 is fixedly connected to a gear 9, and the atomizing nozzle 7 is arranged in a "Z" shape. In the initial state, the nozzle of the atomizing nozzle 7 is located in the left area of the bottom front of the storage box 4, and the outer side of the connecting rod 802 is fixedly connected to a fixing sleeve 10.

[0031] One side of the fixing sleeve 10 is fixedly connected to a connecting frame 11 , and one side of the connecting frame 11 is fixedly connected to a toothed plate 12 . The toothed plate 12 is meshed with the gear 9 .

[0032] By setting the gear 9 and the tooth plate 12, when the connecting rod 802 moves upward, the connecting rod 802 will drive the fixed sleeve 10 to move upward, the fixed sleeve 10 drives the connecting frame 11 to move upward, the connecting frame 11 drives the tooth plate 12 to move upward, and the tooth plate 12 drives the gear 9 to rotate clockwise. After the gear 9 rotates clockwise, it drives the atomizing nozzle 7 fixed on the inside to rotate, so that the atomizing nozzle 7 rotates from the left area of the bottom front of the storage box 4 to the right area of the bottom front of the storage box 4 during the clockwise rotation. The rotation of the atomizing nozzle 7 can make the deodorant spray in a swinging manner, thereby increasing the spraying range and further improving the deodorizing effect.

[0033] The outer side of the storage box 4 is provided with a protective shell 13, one side of the protective shell 13 is fixedly connected to the door frame 1, and an opening is provided on the front of the protective shell 13. The atomizing nozzle 7 is located in the opening and is slidably connected to the protective shell 13 through the opening.

[0034] By providing the protective shell 13, the protective shell 13 can shield the gear 9 and the tooth plate 12, preventing the gear 9 and the tooth plate 12 from being exposed to the outside and easily damaged.

[0035] The outer side of the connecting rod 802 is slidably connected to the limiting sleeve 14 , and one side of the limiting sleeve 14 is fixedly connected to the door frame 1 .

[0036] By providing the limiting sleeve 14 , the limiting sleeve 14 can support and limit the connecting rod 802 , making the connecting rod 802 more stable when moving.

[0037] A limit plate 15 is fixedly connected to the back of the door body 2 , and a protective pad 16 is fixedly connected to one side of the limit plate 15 .

[0038] By setting the limit plate 15 and the protective pad 16, the limit plate 15 can limit the rotation of the card plate 3, so that the card plate 3 can only rotate clockwise but not counterclockwise, so that the rotation of the card plate 3 can normally drive the deodorant to be sprayed, and the protective pad 16 can play a buffering role for the card plate 3, so that when the card plate 3 is rotated and reset after using the toilet, the card plate 3 will not directly collide with the limit plate 15 and be damaged.
