Description

Negative pressure extraction portable bottle

The invention is a portable bottle, especially a portable bottle that can contain tea and tea leaves.

There are generally two ways to brew tea. The first and most common way is to brew with hot water, which is mainly to use hot water to quickly release the ingredients in the tea into the water, usually in tens of seconds to 2 minutes. To get delicious tea, the second common way to make tea is to put the tea leaves in cold water or room temperature water for 8-10 hours and then pick up the tea to get delicious tea. Compared with hot water brewing, tea brewed with room temperature water or cold water has a lower content of caffeine and tannins, so you can get a sweeter tea flavor, and it is less likely to affect sleep and stomach.

However, cold brewing of tea is usually quite time-consuming, and it is also necessary to pay attention to the tea steeping time. If the tea is not taken out of the water at the correct time, the flavor of the tea will still deteriorate. Therefore, the mainstream way of brewing tea is still brewing with hot water.

The negative pressure extraction portable bottle 10 also includes a manual suction pump 39 installed on the bottle cap 26. The suction pump 39 includes an outer body 60 fixed in the recess 28 of the bottle cap 26. The outer body 60 includes a groove 62. The outer body 60 further includes an assembly hole 64 extending from the outer peripheral surface to the groove 62 and a plurality of exhaust holes 66 formed around the assembly hole 64. Each exhaust hole 66 extends from the outer peripheral surface to and The tank chamber 62 is connected. The top end of the outer body 60 can be combined with the bottle cap 26 by bonding, and the groove 62 of the outer body 60 is in communication with the perforation 32 and a plurality of exhaust holes 36 (as shown in Figures 4 and 5).

The assembly hole 64 of the outer body 60 is air-tightly provided with a valve body 82. One end of the valve body 82 located inside the groove 62 forms an elastic flange 84. The elastic flange 84 is in a natural state (without external force). Air-tightly seal each suction hole 66 from the inside of the tank 62 (as shown in Figure 5), so that the tank 62 and the chamber 24 are not connected (as shown in Figure 4), so that the negative pressure extraction portable bottle The air outside 10 cannot enter the chamber 24 of the bottle 20.

The grip portion 44 can push the piston 52 to reciprocate in the piston chamber 56 (as shown in Figures 4 and 6). According to the diagram in Figure 4, the piston 52 is preferably a separate design from the rod body 42. That is to say, when the piston member 41 is installed on the bottle cap 26, the piston 52 and the rod body 42 are separated first, so that The rod 42 can pass through the through hole 32. After the end 46 of the rod 42 is located in the recess 28, the piston 52 is further screwed to the end 46 of the rod 42.

According to the diagram, the negative pressure extraction portable bottle 10 further includes a soaking container 72. The soaking container 72 includes a bottle 74. The bottle 74 is provided with a space 76 and a plurality of penetrating small holes 77 are provided at the bottom of the space 76 for soaking. The container 72 further includes a lid 78 that is detachably combined with the bottle 74. A second magnetic element 80 (as shown in Fig. 4) is incorporated in the lid 78. In addition, the second magnetic element 80 is preferably a magnet, In addition, the magnetic pole direction of the second magnetic element 80 is opposite to that of the first magnetic element 70, so that the first and second magnetic elements 70 and 80 can attract each other.

For the convenience of explanation, suppose the negative pressure extraction portable bottle 10 of the present invention is used to make cold brewed tea. As shown in Figure 6, first add room temperature water or cold water into the chamber 24 of the bottle body 20, and then mix the granular tea 86 Place it in the space 76 of the infusion container 72, and further put the infusion container 72 containing the tea 86 into the chamber 24 of the bottle body 20. The water 88 in the chamber 24 enters the space through the small holes 77 of the bottle 74. The tea leaves 86 are contacted inside 76, so that the tea leaves 86 are soaked in normal temperature water or cold water. The piston member 41 is further operated to make the piston 52 reciprocately move closer to and away from the perforation 32, and the air in the chamber 24 is drawn out to make the chamber 24 Compared with the atmospheric pressure, it produces a negative pressure state.

In detail, when the piston 52 moves toward the direction of the perforation 32, the air in the chamber 24 is pumped and pushes the elastic flange 84 of the valve body 82 through the air extraction holes 66 to further enter the groove 62 (as shown in Figure 6). As shown), and the air in the groove 62 further enters the piston chamber 56 through the through holes 58, and then when the piston 52 moves away from the perforation 32, the air in the piston chamber 56 and the groove 62 is squeezed. Increase the pressure so that the pressure generated by the air in the groove 62 resists the elastic flange 84 and more closely abuts against the inner ring wall of the groove 62, so that the air suction holes 66 are more tightly sealed by the elastic flange 84, so that when the piston The displacement of 52 away from the perforation 32 cannot squeeze the air into the chamber 24, and further pushing the piston 52 of the piston member 41 away from and close to the perforation 32 can gradually draw out part of the air in the chamber 24, making the chamber 24 Form a negative pressure state.

After the air in the chamber 24 is drawn out to generate a negative pressure state, the piston 52 is pushed to move away from the perforation 32 until the bottom surface of the holding portion 44 abuts against the surface of the bottle cap 26 and the convex portion 50 is accommodated in the lock groove In 34, the piston member 41 is further rotated at a small angle around the axis of the perforation 32, so that the convex portion 50 fits into the lock groove 34, so that the piston 41 cannot move along the axis of the perforation 32, and the sealing ring 48 is further airtight. Each vent hole 36 is pressed against the ground, and each vent hole 36 and the perforation 32 located inside each vent hole 36 are airtightly closed, so that the negative pressure extracts the air outside the portable bottle 10 cannot pass through the perforation 32 or each exhaust The hole 36 enters the chamber 24.

It is worth mentioning that, assuming that due to operational problems, the airtightness of the sealing ring 48 to the exhaust holes 36 and the perforations 32 is not good. Part of the air enters the groove 62 and will still be blocked by the valve body 82 and cannot pass through each. The exhaust hole 66 or the assembly hole 64 enters the recess 28 and the chamber 24.

When the chamber 24 is under negative pressure (less than 1 atmospheric pressure), the tea leaves 86 in the steeping container 72 soaked in water 88 are easier to unfold and release the ingredients of the tea leaves 86 in the water, thus shortening the completion of cold brewing. The time required (approximately 2~2.5 hours).

Assuming that the soaking container 72 has been soaked in water for 2 hours, the negative pressure extraction portable bottle 10 can be reversed so that the cap 26 faces downwards (not shown), so that the second magnetic element 80 of the soaking container 72 can be installed in The first magnetic element 70 on the bottle cap 26 attracts each other. After the negative pressure is restored to extract the portable bottle 10 (the cap 26 faces upward), the first and second magnetic elements 70 and 80 attract each other so that the soaking container 72 is attracted. Keep in the recess 28 of the bottle cap 26 and separate from the water 88 in the chamber 24, so as to avoid the problem that the tea 86 is soaked in water for too long.

In the present invention, an air extraction pump 39 is provided on the bottle cap 26 to extract the air in the chamber 24 (which will also draw out the air in the recess 28) to generate a negative pressure in the chamber 24, so that the water immersed in the water 88 Tea 86 can quickly unfold and release the substances in the tea 86, which can reduce the time to obtain tea (2~2.5 hours) when the tea 86 is soaked in room temperature or cold water.

Through the valve body 82 installed on the outer body 60 of the air extraction pump 39, it can be ensured that the air extraction process of the air extraction pump 39 is operated without opening the cap 26, and the negative pressure extracts the air outside the portable bottle 10. Will enter the chamber 24 and the alcove 28.

The valve body 82 airtightly closes the assembly hole 64 and the air extraction holes 66 and the sealing ring 48 on the piston member 41 airtightly seals the perforations 32 and the exhaust holes 36, so that the chamber 24 can be kept in the negative direction for a long time. The pressure state further shortens the time required to make tea with room temperature water or cold water.

The first magnetic element 70 arranged on the bottle cap 26 cooperates with the infusion container 72 and the second magnetic element 80, which can easily and quickly separate the tea 86 and the water 88 (it has become tea) within an appropriate time (for example, after 2.5 hours of soaking). The tea with better flavor is obtained, so the negative pressure extraction portable bottle 10 of the present invention is suitable for being carried around.

The basic teaching of the present invention has been explained, and many extensions and changes will be obvious to those with ordinary skills in the field. For example, the exhaust pump 39 is not limited to the technical features disclosed in the figure. For example, the bottle cap 26 can be combined with an electric exhaust pump, whether it is a manual exhaust pump or an electric exhaust pump. The pump can be used to extract the air in the chamber 24, so that the chamber 24 generates a negative pressure state, shortening the completion time of cold brewing tea. Alternatively, the negative pressure extraction portable bottle 10 of the present invention may not include the soaking container 72 and the first and second magnetic elements 70 and 80. In this state, the tea leaves 86 can be directly poured into the water 88, and the coldness can still be shortened. The time to make the tea.

Since the invention disclosed in the specification can be implemented in other specific forms that do not depart from the spirit or general characteristics of the invention, and some of these specific forms have been pointed out, the embodiments disclosed in the specification should be regarded as illustrative rather than restrictive. The scope of the present invention is defined by the scope of the attached patent application, rather than the above description.
