Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 In this embodiment: an adjustable spray device for local anesthesia includes a bottle body 1, a hydraulic device 2 installed inside the bottle body 1, a first fixing member 3 sleeved at the top opening of the bottle body 1, a second fixing member 4 inserted into the top of the first fixing member 3, a spray head 5 slidably inserted into the top of the second fixing member 4, the bottom end of the spray head 5 being located inside the second fixing member 4 and connected to the hydraulic device 2 through a connecting pipe 6, a flow groove 7 being formed inside the spray head 5, the bottom end of the flow groove 7 being connected to the connecting pipe 6, a spray head 8 being installed on the side of the spray head 5, the top end of the flow groove 7 being interconnected with the spray head 8, a second sliding groove 52 being formed inside the flow groove 7, a blocking groove 51 being formed inside the flow groove 7 and on the side opposite to the second sliding groove 52, a blocking plate 9 being slidably connected inside the flow groove 7, the other end of the blocking plate 9 being engaged inside the blocking groove 51, completely blocking the flow groove 7. After use, the spraying device slides one end of the sealing plate 9 into the second sliding groove 52, causing the other end of the sealing plate 9 to slide into the inner side of the sealing groove 51, completely blocking the flow groove 7 and preventing spraying in case of accidental contact, thus avoiding waste.

[0023] The hydraulic device 2 and the spray head 5 operate on the same principle as alcohol spray in the prior art.

[0024] In a preferred embodiment, an adjusting screw 15 is threadedly inserted into the side of the spray head 5. One end of the adjusting screw 15 extends to the outside of the spray head 5, and the other end extends to the inside of the second sliding groove 52 and is rotatably connected to one end of the sealing plate 9. By turning the adjusting screw 15 to rotate it inside the spray head 5, the sealing plate 9 can slide better inside its second sliding groove 52.

[0025] In a preferred embodiment, a second screw 13 is threaded into the inner side of the second fixing member 4. An adjusting cylinder 14 is fixedly sleeved on the outer side of the second screw 13 and inside the second fixing member 4. The second screw 13 is located at an eccentric position on the adjusting cylinder 14, which is directly below the spray head 5. One end of the second screw 13, away from the second fixing member 4, extends to the outside of the second fixing member 4. By turning the second screw 13 to rotate it inside the second fixing member 4, the adjusting cylinder 14 can be better driven to rotate eccentrically. This changes the distance between the top of the adjusting cylinder 14 and the bottom of the spray head 5, thereby changing the lowest point of the spray head 5 each time it descends. This allows for adjustment of the amount of anesthetic spray sprayed each time, improving the precise control of the amount of anesthetic spray used.

[0026] In a preferred embodiment, a recessed rectangular slot 31 is formed at the top of the first fixing member 3 and to the left of the second fixing member 4. Symmetrically distributed first sliding grooves 32 are formed on the inner side of the slot 31. A first clamping block 10 is installed inside the slot 31, and the left and right ends of the first clamping block 10 are slidably connected to the inner side of the first sliding groove 32. A second clamping block 11 is installed on the top of the first clamping block 10, and a first screw 12 is threadedly inserted into the top of the second clamping block 11. The bottom end of the first screw 12 is rotatably connected to the inner side of the second clamping block 11. By pushing and pulling the first clamping block 10 to make it slide back and forth inside the first sliding groove 32, and simultaneously turning the first screw 12 to make it rotate inside the first clamping block 10 and the second clamping block 11, the first clamping block 10 and the second clamping block 11 can be well separated and fitted. After rotating the second screw 13 to a suitable position, by adjusting the position and fit of the first clamping block 10 and the second clamping block 11, the second screw 13 is locked in the first clamping block 10 and the second clamping block 11, thereby limiting the position of the second screw 13 and ensuring that the amount of anesthetic spray sprayed each time is the same after adjustment, thus improving the stability of the device.

[0027] In a preferred embodiment, one end of an inlet pipe 21 is fixedly connected to the bottom of the hydraulic device 2, located inside the bottle body 1, and the other end of the inlet pipe 21 is completely immersed in the anesthetic fluid 16. When the hydraulic device 2 is in operation, the fixedly connected inlet pipe 21 can better pump the anesthetic fluid 16 from inside the bottle body 1 into the hydraulic device 2.

[0028] In a preferred embodiment, the left and right ends of the hydraulic device 2 are connected to the top of the bottle body 1, and the inner side of the first fixing member 3 is tightly fitted to the left and right ends of the hydraulic device 2. The tight fit between the inner side of the first fixing member 3 and the left and right ends of the hydraulic device 2 ensures that it is securely fixed to the top of the bottle body 1.

[0029] In a preferred embodiment, the bottom end of the spray head 5 is in contact with the outer surface of the adjusting body 14. When the top end of the spray head 5 is pressed down to move it downward, the bottom end of the spray head 5 is in contact with the surface of the adjusting body 14 to limit the spray head 5.

[0030] The working principle and usage process of this utility model are as follows: When the operator presses the top of the spray head 5, it moves downwards, causing the hydraulic device 2 connected to the bottom end of the connecting pipe 6 to operate. This causes the inlet pipe 21, which is fixedly connected to the bottom end of the hydraulic device 2, to draw the anesthetic liquid 16 from inside the bottle 1 into the hydraulic device 2. The liquid then flows through the connecting pipe 6 into the flow groove 7 inside the spray head 5, and is sprayed through the spray head 8 connected to the flow groove 7. Simultaneously, the first screw 12 inside the second fixing member 4 is adjusted to drive the adjusting cylinder 14 to rotate eccentrically. This changes the distance between the top of the adjusting cylinder 14 and the bottom of the spray head 5, thus altering the lowest point of the spray head 5's descent each time. This allows for adjustment of the anesthetic spray volume per spray, improving the precision control of the anesthetic spray usage. After rotating the second screw 13 to the appropriate position, adjusting the position and fit of the first clamping block 10 and the second clamping block 11 secures the second screw 13 within them, limiting its position and ensuring that the amount of anesthetic sprayed each time is consistent, thus improving the stability of the device. After use, turning the adjusting screw 15 inside the spray head 5 allows the sealing plate 9 to slide better inside its second sliding groove 52, causing the other end of the sealing plate 9 to slide into the inner side of the sealing groove 51, completely blocking the flow groove 7 and preventing accidental spraying and waste.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
