Description

Technical Field

[0001] The utility model relates to a self-priming quantitative liquid adding bottle. Background Art

[0002] In many production and life scenarios, we often need to add liquid in a quantitative manner, such as accurately adding a certain amount of liquid seasoning when cooking. However, the commonly used liquid adding bottles are relatively simple in structure and cannot accurately add liquid. When adding liquid, operators usually rely solely on feeling to estimate, which may result in large errors.

[0003] Take the common addition of liquid seasonings in the kitchen as an example. Assume that it has been verified in practice that the best ratio of liquid seasonings required to cook a delicious dish is: 5ml soy sauce, 20ml rapeseed oil, 4ml cooking wine, 5ml light soy sauce, and 3ml sesame oil. However, many seasoning bottles currently used in the kitchen cannot add these seasonings quantitatively according to the required ratio. Chefs can often only add them based on their feelings, resulting in large changes in the taste of the dishes. Utility Model Content

A pressure rod is provided in the adjustment area, one end of the pressure rod is connected to the piston, and the other end extends from the top of the shell body. A top cover is fixed on the top of the shell body, and a limiting hole matching the outer diameter of the pressure rod is provided in the middle of the top cover. The pressure rod extends out of the shell from the limiting hole, and the pressure rod is slidably connected to the inner wall of the limiting hole. A positioning device for controlling the upper limit of the upward movement of the pressure rod is also provided in the adjustment area.

[0006] In this embodiment, a pressing plate is fixed to one end of the pressing rod extending out of the housing, and the pressing plate is used to control the maximum distance the pressing rod moves downward.

[0007] In this embodiment, the liquid bottle is also provided with a handle for conveniently lifting the liquid bottle.

[0008] In this embodiment, the bottle cap is provided with an air hole connecting the solution cavity with the outside.

[0009] In this embodiment, the positioning device includes a screw, a dial, a second stopper and a retaining ring. The dial is arranged horizontally and rotatably installed in the adjustment area. One side of the dial extends out from the front of the shell. A screw hole matching the size of the screw is provided in the middle of the dial. The screw is arranged vertically and threadedly installed in the screw hole. A limiting guide device for limiting the rotation of the screw is also provided in the adjustment area, so that when the dial is rotated, the screw can move up and down. A second stopper is fixed to the lower end of the screw. A retaining ring matching the second stopper is fixed to the middle part of the pressure rod and located below the second stopper. When the pressure rod moves upward to the set position, the retaining ring is blocked by the second stopper to realize the control of the upper limit position of the pressure rod. By controlling the upper limit of the upward movement of the pressure rod, the distance the piston moves upward can be controlled, thereby controlling the volume of the solution sucked into the quantitative chamber and realizing the quantitative pouring of the solution.

[0010] In this embodiment, the position limiting guide device includes a guide rail arranged in the adjustment area and arranged parallel to the screw rod. Slide blocks are arranged at the upper and lower ends of the screw rod. The slide blocks at both ends of the screw rod are slidably installed in the guide rail.

[0011] In this embodiment, a scale is provided on the side of the screw facing the shell along the length direction, and a transparent display window is provided on the shell at a position corresponding to the screw, and the display window matches the size of a scale on the screw. Here, the downward movement of the screw is matched with the suction volume of the quantitative chamber to form a scale, and the scale on the screw can be seen through the display window, thereby accurately realizing the control of pouring out the solution.

[0012] In this embodiment, a tension spring is also sleeved on the pressure rod between the retaining ring and the top cover, one end of the tension spring is fixed to the top cover, and the other end is fixed to the retaining ring.

The lock tongue is arranged in the adjustment area of ​​the shell, and a through hole matching the outer diameter of the pull pin is provided on the shell at a position corresponding to the lock tongue. The pull pin is slidably installed in the through hole, one end of the pull pin is fixedly connected to the lock tongue, and the other end extends out of the shell. The pull pin is arranged on one side of the shell and is provided with a spring, one end of the spring is fixed to the lock tongue, and the other end is fixed to the inner wall of the shell. A plug is fixed on the end of the pull pin extending out of the shell, and a first stopper matching the lock tongue is fixed on the pressure rod below the retaining ring. When the first stop is limited by the lock tongue again, the downward pressure is stopped, thus completing the process of quantitatively absorbing solution and discharging the quantitative solution again, and finally pouring the solution out of the bottle mouth, so that quantitative liquid discharge is achieved by utilizing the cooperation of the positioning device and the locking device.

[0014] Due to the above structure, the device has the following advantages:

[0015] 1. The device can quantitatively absorb the solution in the solution cavity of the liquid bottle by using a quantitative suction and discharge device, and then discharge the absorbed solution into the liquid storage flow channel of the bottle mouth, so as to be convenient for pouring out in subsequent use. The quantitative suction and discharge device uses a piston mechanism and the first and second one-way valves to realize the one-way suction and discharge of the solution in the liquid bottle. It has a simple structure and is easy to use.

[0016] 2. The device is also provided with a positioning device and a locking device. The positioning device controls the upper limit of the upward movement of the pressure rod, that is, the distance that the piston moves upward, thereby controlling the volume of the solution sucked into the quantitative chamber, and realizing the quantitative pouring out of the solution. The locking device is used to lock the lower limit position of the pressure rod. When in use, when the pressure rod is pressed down and moves downward to the first stopper, and after passing the lock tongue, the pressure rod is released. At this time, the pressure rod rebounds under the action of the tension spring, so that the first stopper abuts against the bottom of the lock tongue, thereby locking the pressure rod in this position. When it is necessary to pour out the solution in the bottle, the pull pin is pulled outward, the lock tongue retracts, and the first stopper is released. When the stopper is locked, the pressure rod continues to rebound under the action of the tension spring until the stop ring hits the second stopper and stops rebounding. At the same time, the piston moves upward in the quantitative chamber to absorb the solution from the solution chamber. When the pressure rod rebounds into place, the pressure rod is pressed downward again, and the piston pushes the solution in the quantitative chamber into the liquid storage channel. When the first stopper is limited by the lock tongue again, the downward pressure stops. In this way, the process of quantitatively absorbing the solution and discharging the quantitative solution is completed. Finally, the solution can be poured out from the bottle mouth. In this way, quantitative liquid discharge is achieved by utilizing the cooperation of the positioning device and the locking device.

[0017] 3. The screw of the positioning device of the device is provided with a scale, and the shell is provided with a transparent display window for displaying the scale. In this way, the scale is formed by matching the downward movement of the screw with the suction volume of the quantitative chamber. The scale on the screw can be seen through the display window, thereby accurately realizing the control of pouring out the solution.

[0018] In summary, the utility model has a simple structure, is easy to use, and can ensure the accuracy of the amount of added solution, thereby improving the stability of cooking and the quality of dishes. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The positioning device includes a screw 26, a dial 27, a second stopper 262 and a retaining ring 235. The dial 27 is arranged horizontally and rotatably installed in the adjustment area 21. One side of the dial 27 extends from the front of the shell. A screw hole matching the size of the screw 26 is provided at the central axis of the dial 27. The screw 26 is arranged vertically and threadedly installed in the screw hole of the dial 27. A limiting guide device for limiting the rotation of the screw 26 is also provided in the adjustment area 21. The limiting guide device includes a guide rail fixed on the inner wall of the adjustment area 21 and arranged parallel to the screw 26. Slide blocks are provided at the upper and lower ends of the screw 26. The screw 26 is slidably installed in the guide rail through the slide blocks at both ends. The limiting guide device ensures that when the dial 27 is rotated, the screw 26 does not rotate, so as to realize the rotation of the screw The rod 26 moves up and down, and a second stopper 262 is fixed at the lower end of the screw rod 26. A retaining ring 235 matching the second stopper 262 is fixed at the middle part of the pressure rod 23 and located below the second stopper 262. When the pressure rod 23 moves upward to the set position, the retaining ring 235 is blocked by the second stopper 262 to achieve control of the upper limit position of the pressure rod 23. A tension spring 234 is also provided on the pressure rod 23 between the retaining ring 235 and the top cover.

[0030] The locking device includes a first stopper 231, a lock tongue 233 and a pull pin 232. The lock tongue 233 is arranged in the adjustment area 21 of the shell. A through hole matching the outer diameter of the pull pin 232 is arranged on the shell at a position corresponding to the lock tongue 233. The pull pin 232 is slidably installed in the through hole. One end of the pull pin 232 is fixedly connected to the lock tongue 233, and the other end extends out of the shell.

On the pressure rod 23, below the retaining ring 235, a first stopper 231 cooperating with the lock tongue 233 is fixed. When in use, the pressure rod 23 is pressed down, so that the first stopper 231 moves downward and passes over the locking tongue 233 (because the upward side of the locking tongue 233 is an inclined surface, and the downward side of the first stopper 231 is also an inclined surface, so that when the first stopper 231 moves downward and contacts the locking tongue 233, due to the effect of the inclined surface, the first stopper 231 pushes the locking tongue 233 to compress the spring and retract, thereby passing over the locking tongue 233), and the pressure rod 23 is released. At this time, the pressure rod 23 rebounds under the action of the tension spring 234, so that the first stopper 231 abuts under the locking tongue 233, thereby locking the pressure rod 23 in this position. When it is necessary to pour out the solution in the bottle, the pull pin 232 is pulled outward, the locking tongue 233 retracts, and the first stopper 23 is released. 1 is locked, at this time, the pressure rod 23 continues to rebound under the action of the tension spring 234 until the retaining ring 235 hits the second stopper 262 and stops rebounding. At the same time as the pressure rod 23 is mentioned above, the piston 24 moves upward in the quantitative chamber 22 to achieve the action of sucking the solution from the solution chamber 14. When the pressure rod 23 rebounds to the right position, the pressure rod 23 is pressed downward again, and the piston 24 pushes the solution in the quantitative chamber 22 into the liquid storage channel 111. When the first stopper 231 is limited by the locking tongue 233 again, the downward pressure stops, thus completing a quantitative solution absorption and quantitative solution discharge process, and finally the solution can be poured out from the bottle mouth 11. In this way, the quantitative liquid discharge is achieved by the cooperation of the positioning device and the locking device.
