Description

Technical Field

[0001] This utility model relates to the field of liquid detection technology, specifically a measuring spoon that can measure liquids by color. Background Technology

[0002] A spoon is a small dipper shaped like a crank handle. Over a long period of development, it has evolved into the various types of spoons that people use widely today. Its main uses are for holding seasonings or scooping liquid foods such as soup and rice, as well as for testing some liquids.

[0003] For example, the utility model patent with publication number CN214539263U discloses a measuring spoon that can measure by color, which relates to the field of liquid detection technology. Specifically, it is a measuring spoon that can measure by color, including a spoon head. The lower part of the spoon head has a first through hole with a thread inside. The spoon head is connected to a screw through the thread of the first through hole. A sealing rubber base plate is fixedly connected to the upper surface of the screw. A fixing plate is fixedly connected to the outer surface of the spoon head. This color-measuring measuring spoon, through the cooperation of a screw and a sealing rubber base plate, allows for adjustment of the spoon head's volume by rotating the rotating column, which in turn moves the sealing rubber base plate up and down. When the sealing rubber base plate reaches the top of the spoon head, it seals the spoon head, protecting its internal cleanliness. However, when using test strips to measure the pH value of the liquid inside the measuring spoon, it presents a problem: reading the pH value is inconvenient, requiring manual removal of the test strip from the spoon, ultimately reducing the color resolution of the test strip. Therefore, we propose a color-measuring measuring spoon. Utility Model Content

When the rotating block is rotated counterclockwise by the operating handle, the rotating block drives the rotating plate to rotate counterclockwise. This, in turn, causes the first follower shaft to rotate, which in turn drives the first pinion to rotate. The first pinion then drives the large gear to rotate in the opposite direction, which in turn drives the second follower shaft to rotate. The second follower shaft then drives the second pinion to rotate, which in turn drives the moving rack to move forward. This, in turn, causes the moving plate to move forward, thus moving the test paper forward. This invention achieves the effect that when the rotating block is rotated, the test paper placed in the moving groove moves closer to the measuring spoon body, improving the pH detection efficiency of the liquid inside the measuring spoon and enhancing convenience.

Equipped with a spring, test strip clamping plate, guide post, guide rail, and guide groove, the device allows the guide post to slide within the guide groove during the forward movement of the moving plate. Due to the shape of the guide rail, the sliding of the guide post within the guide groove further drives the test strip clamping plate downward. The test strip clamping plate continuously clamps the test strip. Throughout this process, the spring remains compressed, facilitating the clamping and removal of the test strip.

A rotating block 24 is fixedly connected to the rear end of the rotating plates 23.

[0024] In this embodiment, a guide rail 218 is fixedly connected to the upper side of the inner end of the movable groove 25, and a guide groove 219 is opened at the lower end of the guide rail 218. A spring 215 is fixedly connected to the inner wall of the top end of the test paper clamping groove 214, and a test paper clamping plate 216 is fixedly connected to the lower end of the spring 215. A guide post 217 is fixedly connected to the middle of the upper end of the test paper clamping plate 216, and the spring 215 is sleeved on the guide post 217. The upper end of the guide post 217 is slidably connected to the guide groove 219.

[0025] Specifically, the device is equipped with a spring 215, a test paper clamping plate 216, a guide post 217, a guide rail 218, and a guide groove 219. During the forward movement of the moving plate 213, the guide post 217 slides within the guide groove 219. Due to the shape of the guide rail 218, the guide post 217 slides within the guide groove 219, thereby driving the test paper clamping plate 216 to move downward. The test paper clamping plate 216 continuously clamps the test paper. During this process, the spring 215 remains compressed, facilitating the clamping and removal of the test paper.

[0026] In this embodiment, a slot 26 is provided on the rear side of the rotating block 24, and the slot 26 is connected to the moving slot 25.

[0027] Specifically, ensure that the test strip can enter the moving slot 25 through the slot 26.

[0028] In this embodiment, the right end of the second follower shaft 29 passes through the rotating block 24, and the outer end of the second follower shaft 29 is rotatably connected to the rotating block 24 through a bearing.

[0029] Specifically, it ensures that the second follower shaft 29 does not interfere with the rotating block 24 during rotation.

[0030] In this embodiment, the guide post 217 passes through the upper end of the movable plate 213, and the outer end of the guide post 217 is slidably connected to the movable plate 213.

[0031] Specifically, ensure that the guide post 217 does not interfere with the moving plate 213 during the movement process.

[0032] In this embodiment, the upper end of the guide post 217 is rounded, and the outer diameter of the guide post 217 is matched with the inner width of the guide groove 219.

[0033] Specifically, ensure that the guide post 217 does not interfere with the guide groove 219.

[0034] In this embodiment, the guide rail 218 is set with its front end horizontal and its rear end horizontal. The height of the rear end of the guide rail 218 is higher than the height of its front end, and the front end and the rear end of the guide rail 218 are connected by an arc.

[0035] Specifically, ensuring that the guide post 217 moves within the guide groove 219 enables the vertical movement of the guide post 217.

[0036] In this embodiment, a bottom limiting plate 211 is fixedly connected to the lower end of the fixed base 21, and the upper end of the bottom limiting plate 211 abuts against the rotating block 24.

[0037] Specifically, the bottom limiting plate 211 can limit the movement of the rotating block 24.

[0038] In this embodiment, two symmetrically arranged operating handles 220 are fixedly connected to the rear side of the lower end of the rotating block 24, and the outer ends of the operating handles 220 are treated with anti-slip treatment.

[0039] Specifically, the rotating block 24 can be directly operated by operating the handle 220.

[0040] Working principle: When the handle 220 drives the rotating block 24 to rotate counterclockwise, the rotating block 24 drives the rotating plate 23 to rotate counterclockwise. This causes the first follower shaft 22 to rotate, which in turn drives the first pinion 27 to rotate. The pinion 27 then drives the large gear 28 to rotate in the opposite direction. The large gear 28 then drives the second follower shaft 29 to rotate, which in turn drives the second pinion 210 to rotate. The second pinion 210 then drives the moving rack 212 to move forward, which in turn drives the moving plate 213 to move forward, thus moving the test strip forward. During the forward movement of the moving plate 213, the guide post 217 slides within the guide groove 219. Due to the shape of the guide rail 218, the guide post 217 slides within the guide groove 219, thereby driving the test paper clamping plate 216 to move downward. The test paper clamping plate 216 continuously clamps the test paper. During this process, the spring 215 remains compressed, facilitating the clamping and removal of the test paper. This invention enables the test paper placed in the moving groove 25 to move closer to the measuring spoon body 1 when the rotating block 24 is rotated, improving the pH detection efficiency of the liquid in the measuring spoon body 1 and enhancing convenience.
