Description

Technical Field

[0001] This utility model relates to the field of shampoo bottle technology, specifically a shampoo bottle capable of dispensing a measured amount of liquid. Background Technology

[0002] Shampoo is an indispensable cleaning product in daily life and hair care. As people's demands for quality of life continue to rise, they also have higher expectations for the shampoo user experience, with precise control of shampoo dispensing volume becoming a key concern.

[0003] Traditional shampoo bottles mostly use a standard pump dispenser design. While this design is convenient, it has significant shortcomings in terms of dispensing volume control. Each pump press often results in an unpredictable dispensing volume, easily leading to too much or too little shampoo. Too much dispensing not only wastes shampoo and increases operating costs but also requires more water and time for rinsing; while too little dispensing may not provide enough for a single wash, requiring multiple presses, increasing cumbersome operation, and reducing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a shampoo bottle that can dispense a measured amount of liquid, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shampoo bottle capable of dispensing a quantitative amount of liquid, comprising a bottle body, a dispensing mechanism at the top of the bottle body, and a metering mechanism at the top of the bottle body;

[0006] The metering mechanism includes a first fixing ring fixedly connected to the top of the bottle. A T-shaped groove is formed at the top of the first fixing ring. A T-shaped ring block is slidably connected in the T-shaped groove. A first fixing plate is fixedly connected to the inner wall of the T-shaped groove. Circles are fixedly connected to the front and rear sides of the first fixing plate. A second fixing plate is fixedly connected to the top of the T-shaped ring block. A fixing cylinder is fixedly connected to the top of the second fixing plate. A slider is slidably connected to the inner wall of the fixing cylinder.

A fixing rod is fixedly connected to the top of the slider. A second fixing ring is fixedly connected to the top of the fixing rod.

[0007] Preferably, the T-shaped ring block has holes on both the front and rear sides that match the circle, and the T-shaped ring block is slidably connected to the surface of the circle through the holes, so that the circle can make the T-shaped ring block slide more stably in the T-shaped ring groove.

[0008] Preferably, the bottom end of the spring is fixedly connected to the bottom of the inner wall of the fixed cylinder, and the fixed cylinder has four grooves on its front and rear sides that match the limiting block. The limiting block is slidably connected to the groove through the surface of the limiting block and slides up and down. The limiting block limits the slider, the fixing rod and the second fixing ring, so that the limiting block, the fixing rod and the second fixing ring have a fixed stroke.

[0009] Preferably, the dispensing mechanism includes an externally threaded cylinder, which is fixedly connected to the top of the bottle body. A press pump head is threadedly connected to the surface of the externally threaded cylinder. An inlet pipe is fixedly connected to the bottom end of the press pump head, and a press head is fixedly connected to the top end of the press pump head. A dispensing pipe is fixedly connected to the outlet of the press head.

[0010] Preferably, the top of the bottle body has a hole so that the liquid inlet tube can be inserted into the bottle body.

[0011] Preferably, the bottom end of the inlet tube is close to the bottom of the inner wall of the bottle, which facilitates the extraction of shampoo from the bottom of the inner wall of the bottle.

[0013] Compared with the prior art, this utility model provides a shampoo bottle that can dispense a measured amount of liquid, which has the following beneficial effects:

[0014] 1. This shampoo bottle features a unique dispensing mechanism that enables precise dispensing. The mechanism comprises a fixed cylinder, a slider, a spring, and a limiting block. When the bottle is pressed, the slider slides within the fixed cylinder, compressing the spring. The spring's elasticity and the limiting block's restriction on the slider's stroke precisely control the amount of shampoo dispensed with each press, preventing waste or inconvenience caused by dispensing too much or too little shampoo. This meets the user's need for precise control over the amount of shampoo used.

[0015] 2. This metered-dispensing shampoo bottle features a pump head dispensing mechanism. An external threaded cylinder connects to the pump head via a threaded connection, facilitating easy installation and removal. The inlet tube at the bottom of the pump head is located close to the bottom of the bottle's inner wall, ensuring ample shampoo intake and minimizing residue and waste. The dispensing tube, fixed inside the pump head's outlet, connects to the inner wall of the second retaining ring in the metering mechanism. During dispensing, the dispensing tube stably dispenses shampoo, making the dispensing operation more convenient and efficient. Attached Figure Description

[0024] This utility model provides the following technical solution:

[0025] Example 1

[0026] Please see Figure 1-3 This utility model provides a technical solution: a shampoo bottle that can dispense a quantitative amount of liquid, including a bottle body 1, a dispensing mechanism 2 and a metering mechanism 3 at the top of the bottle body 1.

[0027] The dispensing mechanism 3 includes a first fixing ring 31, which is fixedly connected to the top of the bottle body 1. A T-shaped ring groove 32 is provided on the top of the first fixing ring 31. A T-shaped ring block 33 is slidably connected in the T-shaped ring groove 32. A first fixing plate 34 is fixedly connected to the inner wall of the T-shaped ring groove 32. Circles 35 are fixedly connected to the front and rear sides of the first fixing plate 34. A second fixing plate 36 is fixedly connected to the top of the T-shaped ring block 33. A fixing cylinder 37 is fixedly connected to the top of the second fixing plate 36. A slider 38 is slidably connected to the inner wall of the fixing cylinder 37. A spring 311 is fixedly connected to the bottom of the slider 38. Limit blocks 39 are fixedly connected to the front, rear, left, and right sides of the slider 38. A fixing rod 312 is fixedly connected to the top of the slider 38. A second fixing ring 313 is fixedly connected to the top of the fixing rod 312.

[0028] The T-shaped ring block 33 has holes on both the front and rear sides that match the circle 35. The T-shaped ring block 33 is slidably connected to the surface of the circle 35 through the holes. The circle 35 can make the T-shaped ring block 33 slide more stably in the T-shaped ring groove 32.

[0029] The bottom end of the spring 311 is fixedly connected to the bottom of the inner wall of the fixed cylinder 37. The fixed cylinder 37 has four slots on its front and rear sides that match the limiting block 39. The limiting block 39 is connected to the slot through the surface and slides up and down. The limiting block 39 limits the slider 38, the fixed rod 312 and the second fixed ring 313, so that the limiting block 39, the fixed rod 312 and the second fixed ring 313 have a fixed stroke.

[0030] Example 2

[0031] Please see Figure 1-4 Furthermore, based on Example 1, liquid dispensing mechanism 2 was obtained.

[0032] The liquid dispensing mechanism 2 includes an external threaded cylinder 21, which is fixedly connected to the top of the bottle body 1. A press pump head 22 is threadedly connected to the surface of the external threaded cylinder 21. An inlet pipe 23 is fixedly connected to the bottom end of the press pump head 22. A press head 24 is fixedly connected to the top end of the press pump head 22. An outlet pipe 25 is fixedly connected to the outlet of the press head 24.

[0033] A hole is provided at the top of the bottle body 1 so that the liquid inlet tube 23 can be inserted into the bottle body 1.

[0034] The bottom of the inlet tube 23 is close to the bottom of the inner wall of the bottle 1, which makes it easy to extract the shampoo from the bottom of the inner wall of the bottle 1.

[0035] The surface of the liquid outlet pipe 25 is fixedly connected to the inner wall of the second fixing ring 313.

[0036] In actual operation, when this device is in use, the dispensing mechanism 2 is responsible for extracting and dispensing the shampoo from the bottle 1. The pump head 22 in the dispensing mechanism 2 is threadedly connected to the external threaded cylinder 21, which is fixed to the top of the bottle 1. A hole is provided at the top of the bottle 1, through which the inlet pipe 23 at the bottom of the pump head 22 is inserted into the bottle 1, with the bottom end of the inlet pipe 23 close to the bottom of the inner wall of the bottle 1. This allows for sufficient absorption of the shampoo in the bottle, reducing residue. When the user presses the pump head 24, it causes the pump head 22 to move downwards, changing the piston structure inside the pump head 22 and creating a negative pressure inside the bottle 1. This draws the shampoo into the pump head 22 through the inlet pipe 23. When the user stops pressing, the spring 311 pushes the slider 38 and the pump head 22 to reset. The piston structure inside the pump head 22 changes again, squeezing out the sucked shampoo through the outlet tube 25 in the outlet of the pump head 24, thus dispensing the shampoo.

[0037] The dispensing mechanism 3 is the key component for controlling the dispensing volume. When the user prepares to press to dispense the liquid, they first come into contact with the dispensing tube 25 connected to the dispensing mechanism 3. The second fixing ring 313 in the dispensing mechanism 3 fixes the dispensing tube 25, and the second fixing ring 313 is connected to the slider 38 via the fixing rod 312. In the initial state, the spring 311 is in a naturally extended state, and the slider 38 is located at a certain position inside the fixed cylinder 37. When the user presses the dispensing tube 25, it will cause the second fixing ring 313, the fixing rod 312, and the slider 38 to move downward. The slider 38 slides up and down on the inner wall of the fixed cylinder 37, and the limiting blocks 39 fixedly connected to it slide synchronously in the grooves opened on the side wall of the fixed cylinder 37. The limiting blocks 39 limit the movement of the slider 38, ensuring that the slider 38 can only move within the set range, thereby ensuring a fixed dispensing volume each time it is pressed. During the downward movement of the slider 38, the spring 311 at the bottom of the inner wall of the fixed cylinder 37 is compressed. When compressed, spring 311 generates an upward elastic force, which increases as the depth of the slider 38 increases. When the user feels that the elastic force of spring 311 has reached a certain level, or when the liquid output reaches the required amount, the user stops pressing. At this time, the elastic force of spring 311 will push slider 38 upward, and slider 38 will drive the fixing rod 312, the second fixing ring 313, and the liquid outlet tube 25 to reset, preparing for the next press.
