Description

Technical Field

[0001] The invention belongs to the technical field of containers, in particular to a device with natural air intake, arc-shaped pipe flow diversion and a pointed mouth to prevent liquid pouring, spraying and dripping. Background Art

[0002] There are many common liquids in life, such as: Water: including tap water, mineral water, purified water. Edible oil: such as peanut oil, soybean oil, olive oil, etc. Alcohol: including medical alcohol, industrial alcohol, etc.

[0003] Beverages: such as cola, Sprite, juice, tea, etc. Milk, soy sauce, vinegar, liquid medicine: such as cough syrup, eye drops, etc., as well as gasoline, diesel, etc. Pouring liquids is a common action in life, but you may also encounter some problems, such as: 1. Liquid splashing: Pouring too quickly or with an inappropriate container opening may cause liquid to splash out and stain the table or clothing.

[0004] 2. Inaccurate pouring: The liquid cannot be poured accurately into the target container, resulting in waste or the need for re-operation.

[0005] 3. Bubble generation: Some liquids are prone to generate bubbles during the pouring process, affecting usage.

[0006] 4. Liquid flows out unevenly: Unreasonable container design or improper pouring method will cause the original container to flow out unevenly, causing dripping, wall hanging and other problems.

[0007] Take the most common traditional 2.5L vinegar pot on the market as an example. It often makes users "laugh and cry" during use. This best-selling vinegar type packaging actually has the following problems: 1. The lack of a separate air inlet causes vinegar to overflow, spill, and leak easily: The traditional 2.5L vinegar kettle is not designed with a separate air inlet, so the balance between the three forces of user pouring force, liquid flow force, and air intake force is not fully considered. When pouring vinegar, the user tilts the bottle, which is the pouring force (manpower), the force when the liquid flows out through the spout is the liquid flow force (gravity), and the air enters the bottle when the liquid flows out, which is the air intake force (air pressure). When the liquid flows out and fills the bottle mouth, there will be a short sealed vacuum effect in the bottle. At this time, the air intake pressure will increase and can only enter from the pouring port and be quickly squeezed into the bottle. The air intake force will counteract the liquid flow force, causing the liquid to be squeezed, shake, and out of control, resulting in overflow, spillage, leakage, etc., while forming bubbles and making gurgling sounds. In this process, users will reduce the pouring force because they do not want the liquid to spill. At this time, the pressure generated by the imbalance between the liquid flow force, the user's pouring force, and the air intake force will intensify and become frequent, causing secondary or even multiple spillages.

[0008] 2. The unreasonable design of the mouth of the pot leads to more serious leakage: the mouth of the traditional 2.5L vinegar pot is extremely unreasonable, and is basically designed on one side of the pot body (in contrast, the mouth of the traditional oil pot is designed in the center of the pot body, and the leakage problem is relatively mild). When pouring vinegar, this kind of mouth position is easy to block the bottle mouth when the liquid flows out, and due to the dual effects of pouring force and gravity, the liquid will flow quickly to the mouth of the pot. At this time, all the liquid force is concentrated on one side of the pot body. When the liquid flows out quickly, it will make it more difficult for air to enter the pot body. The mutual force between liquid and air will cause more serious liquid squeezing, shaking, and loss of control, so the 2.5L vinegar pot has the most serious leakage. 3. The mouth of the pot is too large, resulting in more serious leakage: The diameter of the mouth of the pot is too large, generally more than 3 cm. The overly large mouth design can easily cause a large amount of liquid to flow out of the bottle mouth quickly in a short period of time, causing a large amount of vacuum in the pot body. At this time, the interaction force between the liquid and the air will increase rapidly, causing more serious liquid squeezing, shaking, and loss of control. Therefore, the leakage of the 2.5L vinegar pot is relatively the most serious. 4. The unreasonable design of the shape of the diversion port at the mouth of the pot leads to more serious spillage: The mouth design of the traditional 2.5L vinegar pot is relatively unreasonable. There is no extended diversion tube or diversion groove, and the only diversion ports are common designs on the market, including water drop type, straight type, triangle type, irregular type, round hole type, etc. These irregular diversion ports will cause the liquid to have a more irregular shape when flowing out, and the interaction between the liquids themselves will also cause more serious loss of control, resulting in more serious spillage.

[0009] 5. The splashing problem when collecting the vinegar after pouring: After pouring the vinegar into a traditional 2.5L vinegar kettle, when the bottle body is parallel, the poured liquid will quickly flow back into the kettle body due to the dual forces of gravity and the collection of hands. At this time, the air in the kettle is quickly squeezed to form a large pressure, which will form a reaction force and quickly react to the liquid, quickly squeezing the liquid out of the mouth of the kettle, causing splashing.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] A device with natural air intake, arc-shaped pipe diversion and pointed mouth to prevent liquid pouring, spraying and dripping, comprising: A container 1, wherein the container 1 is used to contain a liquid; A flow guide port 2, wherein the flow guide port 2 is disposed at the upper portion of the container 1, and a flow guide port seal 3 for sealing the flow guide port 2 is disposed on the flow guide port 2, and the flow guide port 2 is used to guide the liquid in the container out; The air inlet 4 is arranged at the upper part of the container, and an air inlet seal for sealing the air inlet 4 is arranged on the air inlet 4.

[0025] Furthermore, the present application takes a vinegar kettle as an example and designs different flow guide ports 2 and air inlets 4 differently, as shown in the following specific embodiments.

[0026] Embodiment 1: like Figure 1 As shown, in this embodiment, the air inlet seal is a bottle cap connected to the air inlet 4 by threads.

[0027] This embodiment is an opening method. As the name suggests, the opening is at the tail of the bottle body. The opening is designed at the tail of the handle of the pot body and is closed by the lid. In this way, air can enter from this opening during the pouring process of the liquid. When the air enters from this opening, it will neutralize the pressure in the bottle during the pouring process of the liquid, so that there will be no short-term vacuum effect in the bottle, which will prevent the liquid from splashing.

[0028] like Figure 6-9 As shown, the guide port seal 3 includes: a cover body 3.1, which is detachably mounted on the guide port 2; a guide pipe 3.2, which is arranged on the cover body 3.1 and connects the two sides of the cover body 3.1; and a plug 3.3, which is arranged in the guide pipe 3.2 and is used to seal the guide pipe 3.2.

[0029] Specifically, a connecting arm 5 is provided between the plug 3.3 and the cover 3.1, and the diversion port plug is designed to be integrally formed. The plug 3.3, the connecting arm 5 and the cover 3.1 are integrally formed by a mold. Such an integrated design is relatively strong and makes the plug 3.3 and the cover 3.1 not easy to be lost.

[0030] The air intake method of this embodiment is relatively simple, that is, an opening is opened at the rear of the handle at the rear of the bottle body, and the opening is sealed and fixed by combining the cover and the thread. The air intake and the arc-shaped flow guide device cooperate with each other. During the pouring process, the arc-shaped flow guide port is used to control the liquid flow rate and liquid fluid flow rate. The air intake neutralizes the pressure in the bottle and does not cause a vacuum effect in the bottle, so the liquid will not flow out intermittently. The liquid is guided by the arc-shaped flow guide device and buffered in the flow guide tube. This cooperation makes the process of pouring liquid very pleasant, and there will be no problems such as spraying, spilling, dripping, and hanging on the wall.

[0031] Embodiment 2: like Figure 2 As shown, in this embodiment, the air inlet seal is a filter that only allows air to enter and prevents liquid from overflowing.

[0032] The filter can be a medical check valve. After the medical check valve is combined with the bottle body, when the user pours the liquid, because the internal interlayer of the medical check valve has a filter formed by high-precision molecules, this filter will only allow air to pass through, while the liquid will be blocked. Therefore, after the medical check valve is combined with the bottle body, during the process of pouring the liquid, air will enter through it, so that the liquid will not leak out. This method is light and beautiful.

[0033] like Figure 6-9 As shown, the guide port seal 3 includes: a cover body 3.1, which is detachably mounted on the guide port 2; a guide pipe 3.2, which is arranged on the cover body 3.1 and connects the two sides of the cover body 3.1; and a plug 3.3, which is arranged in the guide pipe 3.2 and is used to seal the guide pipe 3.2.

[0034] A connecting arm 5 is provided between the plug 3.3 and the cover 3.1. The diversion port plug is designed to be integrally formed by using a mold to integrally form the plug 3.3, the connecting arm 5 and the cover 3.1. Such an integrated design is relatively strong and makes the plug 3.3 and the cover 3.1 not easy to be lost.

[0035] A section of the flow guide tube 3.2 extending out of the cover body 3.1 is provided with an arc, and the front end of the flow guide tube 3.2 is a pointed tip.

[0036] The length of the guide tube 3.2 is controlled at 3 cm to 5 cm, so that the liquid flow path is short, and the pointed arc guide tube is designed to be curved downward, and the outlet of the guide port adopts a pointed design. This design will not block the user's sight when the user is looking for a container to pour into, and will not block the user's sight during the pouring process. Therefore, this pointed design and downward arc design make it easier for users to pour liquid when choosing a smaller storage bottle mouth.

[0037] The pointed nozzle design of the guide pipe better controls the liquid flow state: the front end of the guide port uses a pointed nozzle design. When the liquid flows out, the liquid will first gather in the direction of the pointed nozzle and flow out, resulting in a more comfortable cylindrical flow. The pointed nozzle design has a good gathering effect and will not cause liquid splashing.

[0038] The curved bend design of the flow pipe can further buffer and help control the pouring of vinegar: Since the flow pipe has a curved bend design, the liquid will be buffered in the flow pipe when it flows out, causing the liquid flow rate to slow down. The slower the flow rate, the smaller the flow rate will be, which will make the flow rate of the liquid more controllable. Therefore, the curved flow pipe with a curved tip will make the vinegar flow more controllable when the user pours vinegar.

[0039] The guide tube will buffer twice during backflow to reduce splashing: (the guide tube has an arc-shaped design) after the user has finished pouring the vinegar, when the bottle body is parallel, after pouring the liquid back, the liquid will quickly flow back into the pot body. At this time, due to the arc-shaped design, the liquid will also be buffered during the backflow process. After the buffering, the force of the liquid returning to the bottle is reduced, and the reaction force of the air pressure will also be reduced at the same time. A small amount of buffering will also splash onto the arc-shaped guide wall, which will not cause the liquid to splash out.

[0040] When the flow rate of the guide tube is small, the splashing problem is reduced when it is collected: the pointed mouth design will better cut off the liquid when it is collected after pouring the vinegar. At this time, the splashing and spraying problems during collection will be reduced, and because the guide tube is an arc-shaped design, when the smaller liquid is in the air, it will first fall into the bottle, and the liquid in the guide tube will be refluxed into the bottle (it will be buffered when refluxed), so there will be no splashing, etc.

[0041] The pointed arc-shaped flow guide tube is closed when the flow rate is large to prevent liquid spraying: When the user pours the vinegar pot with too much force, the flow rate of the liquid will be fast, so the flow rate of the liquid will be greater. The outflow rate is too large, and when pouring vinegar with a large flow rate, a full and curved liquid flow shape will appear due to the flow guide tube. At this time, if the user quickly straightens the bottle body, because the flow guide port is an arc-shaped design, the liquid will be buffered in the arc-shaped flow guide tube and then reflux. Because the mouth of the flow guide port is a downward pointed design, it will also wrap the liquid and cut off a part of it when closing, so that the poured liquid is cut off, and the liquid in the flow guide tube will be buffered and flow back into the bottle. The liquid flowing in the air will fall down into the storage bottle. Therefore, when the flow rate is large, when the user finishes pouring the vinegar and closes it, the pointed arc-shaped flow guide tube can reduce the splashing of the liquid due to reflux and the spraying of vinegar liquid when closing.

[0042] The direction of the pointed arc-shaped guide tube is tilted on the side of pouring liquid, and the tilt angle range is 55°- 65° (arc range is 0.94 rad ~ 13π / 36rad). When it is above 20° and below 55° (arc range is above 20π / 180red and below 0.94 rad), the tilt angle of the arc-shaped guide tube is too large, and the diversion route is small during the liquid diversion process. In this way, when the liquid is poured and collected, the refluxed liquid cannot flow back into the bottle in the first time, so there will be problems of liquid hanging on the wall and dripping. When the tilt angle range is above 65° and below 90° (arc is above 13π / 36rad and below π / 2rad), the tilt angle of the arc-shaped guide tube is too small, and there is no opportunity to buffer the liquid during the liquid diversion process, so it is uncontrollable when pouring the liquid, and there is no opportunity to buffer when the liquid is collected after it is completed, so it will be sprayed out at the moment the user collects it. Therefore, it is best to control the inclination angle of the guide tube at 55°- 65° (radian range is 0.94 rad ~ 13π / 36rad). Such an angle will have a secondary buffer, which is more controllable when pouring and collecting, and can prevent wall hanging and dripping when collecting.

[0043] The pointed mouth design of the arc-shaped guide tube will reduce the problem of liquid dripping when it is collected: the pointed mouth design will reduce the problem of vinegar liquid dripping when it is collected after pouring the vinegar. Due to the pointed mouth design, when the flow rate is small, the tension between the liquid and the guide tube is small. The small surface tension will not cause the liquid to flow into the outer wall of the guide port, so it can only flow into the storage bottle or flow back into the vinegar bottle. When liquid in a dripping state appears during the backflow, since the guide tube is an arc-shaped design, there is no force to push the dripping liquid into the guide port. Therefore, when the flow rate decreases and liquid in a dripping state appears, the arc-shaped guide tube and the pointed mouth of the guide port will cause the dripping liquid to flow back into the bottle or drip into the storage bottle.

[0044] The pointed arc-shaped flow guide tube design will reduce the problem of liquid hanging on the wall when the vinegar is poured: due to the pointed design, when the flow rate is small, the liquid will be controlled in the flow guide tube due to tension and will not flow down the outer wall. When there is no flow, the flow guide tube is designed in an arc shape, so there is no force to push the liquid out of the flow guide port in small amounts. Therefore, when the flow rate decreases, the arc design will cause the liquid to flow back into the bottle. Therefore, when users pour vinegar, there will be no problem of liquid hanging on the wall.

[0045] Embodiment 3: like Figure 3 As shown, in this embodiment, the air inlet seal is a check valve type that only allows air to enter and prevents liquid from overflowing.

[0046] The check valve is also called the air intake valve, which prevents the backflow of liquid in the water area. The inside of this check valve is composed of fan petals. When there is pressure, the air intake fan petals will open to allow air to enter, and the check fan petals will close to prevent the liquid from flowing back out. After this check valve is combined with the bottle body, during the process of pouring liquid, air will enter the bottle from the air intake fan petals, and the liquid in the bottle will not flow out. The advantage of this method is that it is simple. You only need to fix the check valve to the bottle body, and no other operations are required. When there is no pressure on the bottle body, the air intake fan petals are closed, and the liquid will not be spilled after accidental contact, nor will the liquid be exposed to the air for a long time. Deterioration. When the user pours the liquid, after the vacuum effect appears in the bottle, this pressure will open the air intake fan petals, so air will be taken in through the air intake valve. Therefore, there will be no problems such as dripping, spraying, and intermittent liquid discharge due to unstable air pressure. When combined with the arc-shaped guide device, it will have a buffering effect on the liquid, and the effect will not be affected by dripping and wall hanging.

[0047] like Figure 6-9 As shown, the guide port seal 3 includes: a cover body 3.1, which is detachably mounted on the guide port 2; a guide pipe 3.2, which is arranged on the cover body 3.1 and connects the two sides of the cover body 3.1; and a plug 3.3, which is arranged in the guide pipe 3.2 and is used to seal the guide pipe 3.2.

[0048] A connecting arm 5 is provided between the plug 3.3 and the cover 3.1. The diversion port plug is designed to be integrally formed by using a mold to integrally form the plug 3.3, the connecting arm 5 and the cover 3.1. Such an integrated design is relatively strong and makes the plug 3.3 and the cover 3.1 not easy to be lost.

[0049] Specifically, the guide tube 3.2 is a tapered tube or a straight tube, the front end of the guide tube 3.2 extends 3-5 cm beyond the surface of the cover body 3.1, and a circular buffer port is built into the rear end of the guide port.

[0050] The guide tube 3.2 (silicone) adopts a conical form (conical tube or straight tube). Many experiments have shown that the length of the guide tube is controlled at 3 cm-5 cm. If it is too long, it will make it difficult to pour into other containers. If it is too short, it will not play a diversion role. Moreover, if it is too short, the splash height will be higher than the guide tube when the vinegar pot is placed flat, which will still cause overflow. In addition, the guide port should not be too large or too small. Many experiments have shown that the diameter of the guide port is best at about 1 cm. If it is too large, the liquid flow rate will be too fast and out of control. If it is too small, it will cause the vinegar to be poured too slowly, and the user will feel tired and impatient.

[0051] The plug on one side of the guide tube will prevent accidental vinegar spillage and other problems: the guide tube has a duckbill-shaped built-in plug on one side, and the plug is designed opposite the sharp mouth. With this design, the plug connection arm will not block the user when pouring vinegar, and the user can also see the storage bottle when pouring vinegar. The plug is fixed in an embedded manner. After it is fixed, there is a buckle inside. Even if the user accidentally knocks over the bottle, the buckle will not break, so the liquid will not splash out due to squeezing. The embedded design can also be covered after the user finishes pouring the vinegar to prevent the vinegar from volatilizing, and it can also prevent foreign objects from falling into the vinegar.

[0052] Embodiment 4: like Figure 4 As shown, in this embodiment, the guide port seal 3 includes: a cover body 3.1, which is detachably mounted on the guide port 2; a guide pipe 3.2, which is disposed on the cover body 3.1 and connects the two sides of the cover body 3.1; and a plug 3.3, which is disposed in the guide pipe 3.2 and is used to seal the guide pipe 3.2.

[0053] The air inlet 4 is a ventilation pipe 3.4 arranged in the guide pipe 3.2. The lower end of the ventilation pipe 3.4 extends to the handle position in the container 1. The air inlet 4 and the ventilation pipe 3.4 are of the same structure.

[0054] In this embodiment, a tube is connected to the ventilation tube from the arc-shaped guide bottle cap, and then the other end of the ventilation tube is inserted into the position of the bottle handle. This ventilation combination method is a relatively optimal method, because when the user pours the liquid, it is still the way he is used to pouring the liquid. No additional operations are required, and the operation can be performed by just opening the plug.

[0055] like Fig.10 , 11 As shown, the air inlet seal 5 is a plug 3.3, and the two have the same structure. The plug 3.3 can block the outlet of the ventilation pipe 3.4 and the outlet of the guide pipe 3.2.

[0056] A connecting arm 5 is provided between the plug 3.3 and the cover 3.1. The diversion port plug is designed to be integrally formed by using a mold to integrally form the plug 3.3, the connecting arm 5 and the cover 3.1. Such an integrated design is relatively strong and makes the plug 3.3 and the cover 3.1 not easy to be lost.

[0057] like Fig.11 As shown, a silicone gasket or an annular groove 3.6 is built into the cover body 3.1 to prevent leakage at the joint.

[0058] A silicone gasket or annular groove is built into the cover body 3.1 to prevent leakage at the joint: a silicone gasket is filled inside the diversion port bottle cap or an annular groove is added to the inner wall of the diversion port ice cover. This design can make the diversion port and the bottle body tighter after the user fixes the diversion port to the bottle body, preventing leakage due to looseness when the user pours vinegar and falling off due to accidental touch during storage.

[0059] Adding a ventilation tube to the vinegar kettle guide tube (the best ventilation tube length is 7cm to 10cm) has the following advantages: Balanced air pressure: When pouring vinegar, the liquid inside the vinegar pot will flow out from the bottle mouth due to the pouring, so a short vacuum change will occur in the bottle. This is because the liquid force and the air intake force squeeze each other, making the liquid spraying difficult to control. Adding an air exchange pipe to the vinegar pot diversion port can allow air to enter the vinegar pot when pouring, balance the air intake force and the liquid flow force, balance the air pressure inside and outside the bottle, make the vinegar flow out more easily, and avoid the situation where the vinegar cannot be poured out or flows out unsmoothly. It can also avoid liquid spraying caused by the imbalance between the liquid circulation force and the air intake force.

[0060] Control the flow rate: When pouring liquid, the pouring force will increase, causing the liquid to flow too fast, which is easy to cause liquid squeezing in a single guide tube, resulting in uncontrollable liquid flow route. After adding a ventilation tube, when the flow rate is too high and the flow rate increases, part of the liquid will flow out of the ventilation tube to achieve the role of diversion and buffering. Therefore, the ventilation tube has the function of controlling the outflow speed of vinegar, facilitating accurate pouring, and avoiding vinegar overflow.

[0061] In this embodiment, the air intake method has the simplest structure. The arc-shaped flow guide device is combined with the traditional bottle body through threads and buckles. After the combination, the liquid can be buffered by the arc-shaped flow guide tube, so the buffered liquid will not form large dripping and spraying. However, when the tilting force of pouring the liquid is too large, the liquid will flow out slowly or stop due to the squeeze with the air. This intermittent liquid outflow will affect the user experience, so it is necessary to embed an air intake pipe in the flow guide tube of the arc-shaped flow guide device. The length of the air intake pipe should not be too long. If it is too long, it will extend to the bottom of the bottle. When the liquid is poured in a small amount, it will not play the role of air intake. Therefore, the length of the air intake pipe is controlled to be 10-15cm for the best. After the arc-shaped flow guide device is built with an air intake pipe, the air will be smoothly inlet when pouring the liquid, neutralizing the pressure in the bottle. In addition, the buffering effect of the arc-shaped flow guide tube, there will be no problems of liquid dripping, spraying, and intermittent liquid discharge.

[0062] Embodiment 5: like Figure 5As shown, in this embodiment, the guide port seal 3 includes: a cover body 3.1, which is detachably mounted on the guide port 2; a guide pipe 3.2, which is disposed on the cover body 3.1 and connects the two sides of the cover body 3.1; and a plug 3.3, which is disposed in the guide pipe 3.2 and is used to seal the guide pipe 3.2.

[0063] like Fig.10 , 11 As shown, the air inlet 4 is a ventilation pipe 3.4 arranged in the guide pipe 3.2, and the lower end of the ventilation pipe 3.4 does not need to extend into the container 1. The air inlet 4 and the ventilation pipe 3.4 are the same structure.

[0064] In this embodiment, a ventilation tube is added on the arc-shaped guide bottle cap. This method fixes the ventilation tube to the bottle cap by opening a mold, which is relatively the most convenient for users. Liquid can be poured by only opening the plug.

[0065] The plug 3.3 is arranged inside the tip of the guide tube 3.2, and the plug is fixed in the guide tube 3.2 by embedding, and there is a buckle inside. A connecting arm 5 is arranged between the plug 3.3 and the cover 3.1, and the guide port plug is designed to be integrally formed, and the plug 3.3, the connecting arm 5, and the cover 3.1 are integrally formed by using a mold, and such an integrated design is relatively firm, so that the plug 3.3 and the cover 3.1 are not easy to be lost.

[0066] A silicone gasket or an annular groove 3.6 is built into the cover body 3.1 to prevent leakage at the joint.

[0067] A buffer interlayer plate 3.5 is provided at the connection between the guide tube 3.2 and the cover body 3.1, and a circular hole is provided in the middle of the buffer interlayer plate 3.5 for the ventilation tube 3.4 to pass through.

[0068] The section of the guide tube 3.2 extending out of the cover body 3.1 is provided with an arc. The front end of the guide tube 3.2 is a pointed mouth.

[0069] The built-in buffer port of the pointed arc-shaped guide tube can better control the liquid flow problem: after the 5mm circular buffer port is built into the rear end of the guide port, when the user pours the flowing liquid in the bottle, when the liquid passes through the mouth of the vinegar bottle itself, the liquid flow rate is large, so the liquid flow is large. The buffer port is smaller than the mouth of the vinegar pot, and the liquid will be buffered at the buffer port, resulting in a decrease in the flow rate of the fluid and the flow rate will be reduced. At this time, a smaller flow will flow from the buffer port to the guide tube, so adding a buffer port can make the liquid buffer for the first time, making the liquid more controllable.

[0070] The air intake method of this embodiment is to connect the air intake pipe in the arc-shaped guide bottle cap through one end of the hose inside the bottle, and then raise the other end of the air intake pipe to the position of the bottle handle. This air exchange combination method is a better air intake combination method, because this method guides the flow through the arc-shaped guide device, buffers and neutralizes the pressure in the bottle through the air intake device when pouring liquid, so the flow of the liquid flowing out is very controllable, without spilling or dripping. In the process of pouring liquid by the user, this combination device does not require other operations, and the user can still pour liquid according to the original method of pouring liquid. It only needs to open the plug (dust cover) of the arc-shaped guide device to pour liquid.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
