[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Combination Figures 1 to 6This embodiment describes a refillable tear gas dispersant, comprising a spray cap assembly 1 and a canister 2. The canister 2 contains a mixing chamber 21, which is connected to the spray cap assembly 1. The spray cap assembly 1 uses a conventional structure to achieve atomized spraying. A tear gas reservoir 3 and a high-pressure gas canister 4 are installed inside the canister 2. A cap 5 is provided at the end of the canister 2 furthest from the spray cap assembly 1. The tear gas reservoir 3 includes an outer casing 31, which is detachably connected to the canister 2. The container is equipped with a storage tank 32, which contains several circumferentially distributed storage cavities 33. The storage cavities 33 are connected to the mixing cavity 21 via a one-way valve 34. The high-pressure gas tank 4 is rotatably mounted relative to the tank body 2. One-way valve 41 is mounted at one end of the high-pressure gas tank 4. When the high-pressure gas tank 4 rotates, the one-way valve 41 is connected to the storage cavities 33 in sequence. The high-pressure gas tank 4 is also axially slidable relative to the tank body 2. The cover 5 is equipped with a rotating component 6 for rotating the high-pressure gas tank 4 and a pushing component 7 for pushing the high-pressure gas tank 4.

[0028] like Figure 2-3 As shown, the tank body 2 includes an upper tank 22 and a lower tank 23, which are connected by a connector 8. A tear gas container 3 is located inside the upper tank 22, and a high-pressure gas tank 4 is located inside the lower tank 23. The connector 8 includes a flange 81 with a vent hole 82. A one-way valve 35 is located at the lower end of the storage chamber 33, communicating with one end of the vent hole 82. A two-way valve 41 is correspondingly located at the other end of the vent hole 82. The upper tank 22 and lower tank 23 are separate, facilitating access to the storage tank 32 and the high-pressure gas tank 4, and allowing communication between the storage tank 32 and the high-pressure gas tank 4 via the vent hole 82 on the flange 81.

[0029] like Figure 2-3 As shown, the upper tank 22 is divided into a mixing chamber 21 by a partition 24. The partition 24 is provided with a through hole 25 that matches the one-way valve 34. The one-way valve 34 is inserted into the through hole 25 and sealed to the through hole 25. After the high-pressure gas and the tear gas are mixed, they enter the mixing chamber 21 through the one-way valve 34. The tear gas is either powder or liquid.

[0030] like Figure 4As shown, the upper and lower end faces of the flange 81 are respectively provided with an external threaded sleeve 83 and an internal threaded sleeve 84. The external threaded sleeve 83 is threadedly connected to the inner wall of the upper tank 22, and the internal threaded sleeve 84 is threadedly connected to the outer wall of the lower tank 23. A pressure ring 85 is provided on the inner side of the internal threaded sleeve 84. The pressure ring 85 is fixedly connected to the flange 81 by a spring 86. The one-way valve 41 is located inside the pressure ring 85. A damping pad 87 is fixedly connected to the pressure ring 85. The pressure ring 85 connected by the spring 86 provides elastic pressure to the high-pressure gas tank 4, and at the same time, it works with the damping pad 87 to prevent the high-pressure gas tank 4 from rotating on its own.

[0031] like Figure 2-4 As shown, a recessed portion 42 is provided on the high-pressure gas tank 4, and a press-type inflation component 43 is provided in the recessed portion 42. The press-type inflation component 43 is similar to a tire inflation structure and is a conventional structure, which will not be described in detail here. One-way valve 41 is located on the side of the high-pressure gas tank 4 away from the recessed portion 42. One-way valve 41 is a press-type one-way valve. When one-way valve 41 on the high-pressure gas tank 4 corresponds to the vent hole 82, the high-pressure gas tank 4 is pushed, so that one-way valve 41 on the high-pressure gas tank 4 is inserted into the vent hole 82. After pressing, one-way valve 41 is opened, so that high-pressure gas enters the vent hole 82. The air pressure in the vent hole 82 increases, thereby opening one-way valve 35, so that high-pressure gas enters the storage chamber 33.

[0032] like Figure 5-6 As shown, one end of the cover 5 is threaded to the inner wall of the lower tank 23, and the end face of the cover 5 is provided with a damping pad 2 51 that abuts against the high-pressure gas tank 4. The damping pad 2 51, together with the damping pad 1 87, prevents the high-pressure gas tank 4 from rotating on its own.

[0033] The rotating assembly 6 includes a ratchet disc 61 and a ratchet lever 62. The ratchet lever 62 is mounted on the cover 5 and rotates elastically relative to the cover 5. The ratchet lever 62 engages with the ratchet disc 61, which is rotatably mounted on the cover 5. A prismatic block 63 is fixedly connected to the ratchet disc 61. The end face of the high-pressure gas tank 4 is provided with a prismatic groove 44 that matches the prismatic block 63. The number of equally spaced ratchet teeth on the outer side of the ratchet disc 61 is the same as the number of storage chambers 33. Each rotation of the ratchet disc 61 allows the one-way valve 41 to connect sequentially with the vent hole 82. A shaft 64 rotates on the cover 5, and a rotating part 65 is fixedly connected to the shaft 64. The shaft 64 is fixedly connected to the ratchet disc 61 and the prismatic block 63 via a pin 66. Rotating the rotating part 65 externally drives the ratchet disc 61 to rotate.

[0034] The pushing assembly 7 includes a pushing disk 71, on which a circumferentially distributed pushing rod 72 is fixed. The pushing rod 72 is slidably connected to the cover 5. The pushing rod 72 is located inside the cover 5 and is fixedly connected to a limiting block 73. The limiting block 73 prevents the pushing rod 72 from sliding out of the cover 5 and increases the contact area between the pushing rod 72 and the high-pressure gas tank 4 to avoid pressure damage to the high-pressure gas tank 4. The pushing disk 71 is provided with a through groove 74, which is opposite to the rotating part 65. The rotating part 65 is an internal hexagonal nut.

[0035] The working principle of this invention is as follows: The canister 2 separately holds the tear gas holding component 3 and the high-pressure gas canister 4. The high-pressure gas canister 4 is rotated by the rotating component 6, so that the one-way valve 41 on the high-pressure gas canister 4 is connected to the storage chamber 33. The one-way valve 41 is opened by the pushing component 7, so that the high-pressure gas enters the storage chamber 33, increasing the internal pressure of the storage chamber 33. Thus, the tear gas and the high-pressure gas are mixed and enter the mixing chamber 21 through the one-way valve 34, completing the high-pressure replenishment of the tear gas. The tear gas is sprayed out through the spray cap component 1. The high-pressure gas and tear gas are stored separately, which can be repeatedly filled and replenished. The structure is simple, the size is small, it is easy to carry, the operation is simple, it is easy to disassemble, and it can be repeatedly filled and used, reducing the cost of use.
