Description

Technical Field

[0001] The utility model relates to a packaging bottle cap, in particular to a laundry detergent liquid discharge device with controllable liquid discharge amount. Background Art

[0002] In the daily use of laundry detergent, quantitative liquid extraction is an important requirement. This is not only related to the washing effect, but also involves resource conservation and environmental protection. However, the traditional laundry detergent bottle cap design often cannot meet this demand. Users usually can only rely on their own subjective judgment when taking liquid, which is neither accurate nor convenient.

[0003] In order to solve this problem, the industry has conducted a series of technical explorations and innovations. Among them, a common technical solution is to achieve quantitative liquid extraction by setting a scale or measuring cup on the bottle cap of the laundry detergent. For example, some laundry detergent bottles are designed with a transparent measuring cup on the top, and users can judge the amount of laundry detergent taken by observing the liquid level in the measuring cup. However, although this solution can achieve quantitative liquid extraction to a certain extent, it still has problems such as inconvenient operation.

[0004] In order to further improve the accuracy and convenience of quantitative liquid dispensing, a new type of laundry detergent bottle cap design has emerged in recent years, namely the quantitative liquid dispensing laundry detergent bottle cap. This bottle cap can automatically complete the quantitative liquid dispensing operation of laundry detergent through the built-in measuring mechanism and control system. The user only needs to press a button or rotate the bottle cap to obtain the preset amount of laundry detergent, without the need for tedious manual operations. For example, a laundry detergent bottle with quantitative liquid discharge is disclosed in Chinese patent publication number CN113060388A, which includes a bottle body and a bottle cap. The bottle body has a bottle mouth on the upper part, and a liquid outlet is provided at the upper end of the bottle mouth. A quantitative structure is provided in the bottle mouth, and the quantitative structure includes a quantitative cavity and a floating structure. The quantitative cavity is used to store and pour out a certain amount of laundry detergent. The liquid outlet is connected to the quantitative cavity. A liquid inlet is provided on the left wall of the quantitative cavity near the top of the quantitative cavity. A sliding tube is vertically provided in the quantitative cavity, and the sliding tube is located directly below the liquid outlet. The diameter of the sliding tube is smaller than the diameter of the liquid outlet. The floating structure includes a sealing cover, a sliding rod and a floating block arranged from top to bottom. The sealing cover is located on the upper side of the liquid outlet, the sliding rod moves up and down in the sliding tube, and the floating block is located on the lower side of the sliding tube and is used to close the liquid inlet. An adjusting structure is provided on the bottle mouth to pour out the laundry detergent in a quantitative manner. This type of quantitative liquid discharge structure is not convenient to use, the liquid discharge volume is small, it is necessary to wait for the floating block to move, and the liquid discharge volume needs to be adjusted through the adjustment structure, which is inconvenient to use and cannot control the liquid discharge and the liquid discharge volume in time.

Since liquids such as laundry detergent are liquids with high viscosity, the residual liquid remaining on the inner wall of the channel is relatively large. In order to make these refluxed residual liquids available for use without causing pollution, a first reflux hole 11c1 connected to the liquid return port 11f is provided at the bottom of the channel of the liquid outlet 11c, and a second reflux hole 11f1 connected to the measuring inner cavity 11e is provided at the bottom of the channel of the liquid return port 11f. The calibers of the first reflux hole 11c1 and the second reflux hole 11f1 are both no more than 1 mm, so as to prevent the liquid in the measuring inner cavity 11e from flowing out during the measuring process.

[0045] A more preferred embodiment is, referring to Figure 3 As shown, the liquid return port 11f does not exceed the position of the liquid outlet 11c on the vertical plane, so as to prevent the liquid from flowing to the liquid return port 11f when pouring and measuring the liquid in the inner cavity 11e, causing the liquid to flow out.

[0046] In a more preferred embodiment, a reflux hole may be provided at the bottom of the extension portion 11 b of the swing rod 12 so that the liquid therein can flow back into the bottle body in a static state.

[0047] like Fig.10 As shown, due to the bumps in the transportation of the goods including the present invention and the periodicity of the sales of the goods, in order to avoid the problem of accidental slight leakage caused by the first reflux hole and the second reflux hole, the present embodiment also has a sealing plug 11g sealed and inserted in the liquid outlet 11c and the liquid return port 11f. The sealing plug 11g has a plug body and can be inserted into the liquid outlet 11c and the liquid return port 11f at the same time. The front end of the sealing plug 11g has a handle portion 11h, which is used for convenient removal of the utility model when it is opened for use.

[0048] In this embodiment, the second component 2 is a button-type structure, which is used to act on the pressure-bearing portion 122 of the swing rod 12 to swing the swing rod 12 to close the second movable door 15 and link the double-end connecting rod 13 to close the first movable door 14.

[0049] like Fig.11 , Fig.12 As shown, the second component 2 includes a button 21, a button seat 22, a spring 23, a sealing ring 24, a sealing cover 25, a mounting ring 26, and a push rod 27. A screw rod 221 is provided on one side of the button seat 22. The screw rod 221 is a hollow structure, and the push rod 27 is slidably arranged therein. The screw rod 221 cooperates with the nut 222 to fix the button seat 22 on the upper part of the handle. The push rod 27 is sleeved with a sealing ring 24, and a sealing seat 223 is provided in the button seat 22. The sealing ring 24 is fitted in the sealing seat 223, and the sealing ring 24 is limited therein by the sealing cover 25. Of course, the sealing cover 25 has a hole to allow the push rod 27 to pass through. A spring 23 is provided between the sealing cover 25 and the push rod insertion position 211 inside the button to reset the button.

[0050] A card body 212 is provided on both sides of the button 21, and a card slot 224 is provided at a position of the button seat 22 corresponding to the card body 212. During assembly, the card body 212 is engaged with the card slot 224 so that the button is installed in the button seat 22, and the mounting ring 26 is used to tightly install the mounting seat 22 in the mounting position corresponding to the handle.

[0051] In this embodiment, in order to avoid the problem that the liquid in the bottle directly flows out from the liquid inlet to the liquid outlet when switching the switching states of the first movable door 14 and the second movable door 15, resulting in the problem that the liquid outlet is difficult to control, it is necessary to close the second movable door first and then open the first movable door. When the swing rod 12 swings, the pushing portion 125 at its front end pushes the second movable door 15 to close the liquid inlet 11d. In this closing process, the first linkage shaft 131 of the double-end connecting rod 13 is not in contact with the linkage groove 144 of the first movable door 14. In the above process, the arc surface 123a in the upper part of the rear end of the linkage hole 123 acts on the second linkage shaft 132, so that the double-end connecting rod 13 swings, and the linkage groove 144 of the first movable door 14 leaves a movable space to meet the requirement that the pushing portion 12 After the second movable door 15 is pushed to close, the first linkage shaft 131 is brought into contact with the rear portion of the linkage groove 144 of the first movable door 14. After the second movable door 15 is closed, the pushing portion 125 continues to slide forward along the sliding space 152 of the linkage seat 151, and the first linkage shaft 131 is brought into contact with the rear portion of the linkage groove 144 of the first movable door 14, so that the first movable door is opened in linkage. In the resetting process, due to the action of the torsion spring 13a, the double-end connecting rod 13 rotates and resets, and acts on the second linkage shaft 132 through the arc surface 123a in the hole, so that the swing rod 12 is reset, and the third linkage shaft 124 at the front end drives the linkage seat 151 to link the second movable door 15 to open, and the first linkage shaft 131 acts on the back of the first movable door 14, so that the first movable door 14 is closed.

[0052] In other further embodiments, the rocker arm 12 may be provided with a reset spring (not shown in the figure) to ensure rapid reset when the key is released and to close the first movable door 14 and the second movable door 15 synchronously.

[0053] The working principle and working process of the utility model are as follows:

[0054] When the laundry detergent bottle is at rest, under the action of the torsion spring or the tension spring, the double-end connecting rod 13 keeps the first movable door 14 at the liquid outlet 11c in a closed state and the second movable door 15 at the liquid inlet 11d in an open state, so that the liquid in the bottle will not overflow from the liquid outlet whether it is during transportation or accidentally dumped.

[0055] When it is necessary to pour out the laundry detergent, the user turns the bottle mouth of the laundry detergent downwards according to his / her habit, and presses the button 21 of the second component 2 with his / her finger, so that the end of the top rod 27 acts on the pressure-bearing portion 122 of the swing rod 12, causing the swing rod 12 to swing. After the second movable door 15 is pushed closed by the pushing portion 125, the double-end connecting rod 13 is continuously linked to overcome the elastic force of the torsion spring to rotate, so that the first movable door 14 at the liquid outlet 11c is opened, and the laundry detergent therein can be poured out.

[0056] When the button is released, the double-end connecting rod 13 is reset under the elastic force of the torsion spring, and the swing rod 12 is also reset, and the whole returns to the static state.

[0057] In the above process, the clothes can also be poured out according to the amount, and the amount poured out can be controlled by the speed of releasing the button.

[0058] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
