Description

Technical Field

[0001] This utility model belongs to the field of medical technology, and in particular relates to a squeeze-type liquid medicine nozzle and sprayer. Background Technology

[0002] Before using a medical sprayer, the powder needs to be manually added to the medicine bottle and stirred to accelerate the mixing of the medicine. However, during this process, the powder tends to float on the surface of the water in the medicine bottle and cannot be fully mixed. A structure that can accelerate the mixing of the powder is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a squeeze-type liquid spray nozzle and sprayer, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a squeeze-type liquid sprayer and sprayer, including a barrel body, and further including: a stirring assembly for accelerating the dissolution of powder; the stirring assembly includes a main shaft, a base frame, a top frame and a mesh cylinder, the main shaft is rotatably connected to the barrel body, the base frame and the top frame are respectively fixedly connected to the upper and lower sides of the main shaft, the top frame has through holes on both sides, and the base frame and the top frame have grooves at the corresponding positions of the through holes.

[0005] Beneficial effects

[0006] This utility model provides a squeeze-type liquid spray nozzle and sprayer, which has the following advantages compared with the prior art:

[0007] The procedure involves medical personnel pressing a mesh tube filled with medicinal powder into the barrel through the through-hole at the top, and connecting the spray bar to the ring. The mesh tube then passes through the through-hole on the top frame. When the top opening of the mesh tube contacts the top frame, the bottom of the mesh tube is pressed into the groove on the base frame. When the top and base frames are in their initial positions, their through-holes align with the through-hole at the top of the barrel. At this point, the medical personnel press two plugs into the through-hole at the top of the barrel to seal it. Then, the medical personnel start motor A, which drives the main shaft fixedly connected to its output shaft. This, in turn, drives the base and top frames, which are fixedly connected to it, to rotate synchronously. During this rotation, water inside the barrel flows more rapidly through the mesh holes on the mesh tube, thus accelerating the flow of the mesh tube. The powdered medicine inside dissolves in water, achieving a uniform mixing effect. Medical staff then activate the motor, causing it to drive a lead screw fixed to its output shaft. This causes the threaded push plate on the lead screw to move linearly along its connection to the barrel, pushing the piston. During piston sliding, the pressure pushes the pressure plate, separating it from the barrel and causing the spring fixed to it to extend. This injects gas from the barrel into the barrel, pressurizing it so that the medicine can be sprayed out through the spray bar. When the piston stops sliding, the spring returns to its original position, causing the pressure plate to move synchronously, ensuring it adheres tightly to the barrel and preventing the medicine from flowing into the barrel.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] Please see Figures 1-4 According to one embodiment of the present invention, a squeeze-type liquid sprayer and sprayer include a barrel body 101, and further include:

[0016] Stirring component 2 is used to accelerate the dissolution of the medicine powder;

[0017] The stirring assembly 2 includes a main shaft 201, a base frame 202, a top frame 203, and a mesh cylinder 204. The main shaft 201 is rotatably connected to the barrel body 101. The base frame 202 and the top frame 203 are respectively fixedly connected to the upper and lower sides of the main shaft 201. The top frame 203 has through holes on both sides, and the base frame 202 and the top frame 203 have grooves at the corresponding positions of the through holes.

[0018] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific base frame 202 described in the above embodiments. For example, the base frame 202 is provided with a damping rubber ring in the groove. The purpose of this setting is to facilitate the increase of the limiting effect on the mesh cylinder 204.

[0019] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific barrel 101 described in the above embodiments. For example, the barrel 101 is provided with a shoulder strap, which can be used to carry the barrel 101 on the body, thereby preventing the medical staff from being unable to lift the barrel 101 due to the excessive weight of the medicine liquid inside.

[0020] Specifically, the mesh tube 204 is sleeved on the top frame 203, and the diameter of the top opening of the top frame 203 is larger than the diameter of the through holes on both sides of the top frame 203.

[0021] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific mesh cylinder 204 described in the above embodiments. For example, the mesh cylinder 204 is provided with multiple rows of mesh holes of the same size. The purpose of this arrangement is to facilitate increasing the mixing speed of the powder.

[0022] Specifically, the barrel 101 is provided with two symmetrical through holes, and a plug 205 is threaded into the through hole. The diameter of the through hole at the top of the barrel 101 is larger than the diameter of the top opening of the mesh tube 204.

[0023] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific barrel 101 described in the above embodiments. For example, a sealing ring is provided at the connection between the barrel 101 and the plug 205. The purpose of this setting is to increase the airtightness of the connection.

[0024] Specifically, the top end of the main shaft 201 is fixedly connected to the output shaft of the motor A206. The motor A206 is fixedly connected to the barrel 101. A ring 307 is fixedly connected to the barrel 101, and the ring 307 is used to connect the spray bar.

[0025] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific motors A206 and 306 described in the above embodiments. For example, motors A206 and 306 should have the function of multi-speed adjustment. The purpose of this setting is to facilitate the adjustment of their output speed through this setting.

[0026] Specifically, a cylinder 207 is fixedly connected to one side of the barrel 101, a piston 303 is slidably connected in the cylinder 207, a push plate 304 is fixedly connected to the top of the piston 303, and the push plate 304 is slidably connected to the barrel 101.

[0027] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific push plate 304 described in the above embodiments. For example, the push plate 304 is provided with a damping rubber strip at the connection between it and the barrel 101. The purpose of this setting is to increase the damping of the sliding of the push plate 304 and make it slide smoothly.

[0028] Specifically, a mesh plate 208 is fixedly connected to the bottom of the cylinder 207, a connecting rod 301 is fixedly connected to the mesh plate 208, and a pressure plate 302 is slidably connected to the connecting rod 301.

[0029] Specifically, a spring 209 is sleeved on the connecting rod 301. One end of the spring 209 is fixedly connected to the mesh plate 208, and the other end of the spring 209 is fixedly connected to the pressure plate 302.

[0030] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific pressure plate 302 described in the above embodiments. For example, the pressure plate 302 is wrapped with a sealing ring. The purpose of this arrangement is to increase its sealing effect.

[0031] Specifically, the push plate 304 is threadedly connected to the lead screw 305. One end of the lead screw 305 is rotatably connected to the barrel 101, and the other end of the lead screw 305 is fixedly connected to the output shaft of the motor 306. The motor 306 is fixedly connected to the barrel 101.

[0032] In this embodiment of the invention, medical personnel press a mesh tube 204 containing medicinal powder into the barrel 101 through a through hole at the top of the barrel 101, and connect the spray bar to the ring 307, so that the mesh tube 204 passes through the through hole on the top frame 203. When the tube opening at the top of the mesh tube 204 contacts the top frame 203, the bottom of the mesh tube 204 is pressed into the groove on the base frame 202. When the top frame 203 and the base frame 202 are in their initial positions, the through holes on them are aligned with the top of the barrel 101. With the through holes aligned, medical staff then press the two plugs 205 into the through holes at the top of the barrel 101 to seal it. Next, the medical staff starts the motor A206, causing the main shaft 201, which is fixedly connected to its output shaft, to rotate. This, in turn, causes the base frame 202 and top frame 203, which are fixedly connected to the main shaft, to rotate synchronously. During this rotation, water inside the barrel 101 flows more rapidly into the mesh of the mesh cylinder 204. The process accelerates the dissolution of the powder in the mesh cylinder 204 in the water, achieving a uniform mixing effect. At this point, medical personnel activate the motor 306, causing the lead screw 305, fixedly connected to its output shaft, to rotate synchronously. This causes the push plate 304, threaded onto the lead screw 305, to begin linear movement along its connection to the barrel 101, thus pushing the piston 303. During the sliding process of the piston 303, under pressure, it pushes the pressure plate 302, separating it from the cylinder 207 and causing the spring 209, fixedly connected to it, to extend. This allows gas from the cylinder 207 to be injected into the barrel 101, pressurizing it so that the liquid medicine inside can be sprayed out through the spray bar. When the piston 303 stops sliding, the spring 209 returns to its original position, causing the pressure plate 302 to move synchronously, thus ensuring it is tightly pressed against the cylinder 207, preventing the liquid medicine from flowing into the cylinder 207.
