Description

Portable bubble water bottle

Technical Field

The invention relates to a bubble water bottle, in particular to a portable bubble water bottle.

Background

With the advantages of drinking bubble water being proposed and more accepted by the public, people can directly purchase bubble water and manufacturers can also develop bubble water machines so that people can make bubble water at home to drink.

Referring to fig. 1, fig. 1 is a schematic cross-sectional view of a conventional bubbling water machine 40. As shown in fig. 1, a conventional bubbling water machine 40 mainly includes a machine table 41, an air cylinder 42, a cup 43, and an air duct 44. The gas cylinder 42 is filled with carbon dioxide and installed at one side of the machine table 41. A cup 43 can be placed on the other side of the machine 41, and the cup 43 is connected with the gas cylinder 42 through a gas tube 44. The gas-guide tube 44 extends into the cup body 43, and carbon dioxide gas in the gas bottle 42 is mixed with water in the cup body 43 to prepare bubble water. Finally, the cup body 43 is taken down from the machine table 41, and the bubble water in the cup body 43 can be directly drunk or poured into other containers for drinking.

Since the bubbling water machine 40 needs to occupy a fixed space, there are also manufacturers who push out more convenient bubbling water bottles. Referring to fig. 2, fig. 2 is a schematic cross-sectional view of a conventional bubble water bottle 50. As shown in fig. 2, a typical conventional bubble water bottle 50 mainly includes an upper cap 51, a cup body 52, an air duct 53, and an air bottle 54. The upper cover 51 is connected to the cup body 52, and the air duct 53 extends from the upper cover 51 into the cup body 52. The gas bottle 54 is connected to one end of the gas-guiding tube 53 exposed out of the upper cover 51, and the carbon dioxide gas in the gas bottle 54 is mixed with the water in the cup body 52 to prepare bubble water.

However, when the bubble water bottle 50 of the handy type is used, the gas bottle 54 is exposed for use. When a user inadvertently strikes the gas cylinder 54 while using the bubble water bottle 50, the connection between the gas cylinder 54 and the gas guide tube 53 may be disconnected. Since the gas cylinder 54 is filled with high-pressure gas, when the gas cylinder 54 is separated from the gas guide tube 53, the gas cylinder 54 may be injected to an indefinite place at a high speed, causing a danger.

In addition, the

air ducts

44 and 53 of the conventional bubbling water machine 40 and bubbling water bottle 50 are both inserted into the centers of the

cups

43 and 52. Since the bubbles are buoyant upward in the liquid, only the water above the outlets of the

gas ducts

44, 53 can be mixed with the carbon dioxide gas, resulting in poor gas dissolving effect.

Therefore, it is one of the important issues to provide a convenient, safe and efficient bubble water device.

As shown in fig. 3 to 7, the portable air bubble water bottle 100 according to the first embodiment of the present invention includes an outer bottle housing 110, a separating trough 130, an upper cover 102, a bottom cover 106 and an air supply device 150.

The outer bottle housing 110 is essentially a cylindrical housing. The outer bottle housing 110 defines a drinking portion 111, a bottle wall 112 and an assembling portion 113 from top to bottom. The drinking portion 111 of the outer bottle housing 110 has a drinking edge 114, which is formed by the edge of the outer bottle housing 110. The bottle wall 112 of the outer bottle shell 110 connects the assembling portion 113 and the drinking portion 111, and the assembling portion 113 has an opening 115. In the present embodiment, the assembling portion 113 extends along the periphery of the bottle wall 112 of the outer bottle housing 110.

The partition groove 130 is provided under the outer bottle housing 110. The partition body 130 defines an air valve groove 132 and an air bottle groove 134 from outside to inside, and the air valve groove 132 has a connecting hole 132 a. The cylinder groove 134 is recessed toward the drinking portion 111. The upper part of the partition groove 130 and the inner side of the outer bottle shell 110 jointly define a liquid storage space SP 1. The valve spool 132 abuts the bottom edge of the assembling portion 113 of the outer bottle housing 110.

The upper cap 102 is connected to the drinking portion 111 of the outer bottle case 110, and in the present embodiment, the upper cap 102 is detachably connected to the drinking portion 111 of the outer bottle case 110 by screw-fastening to seal the liquid storage space SP 1. Specifically, the cap 102 of the present embodiment has an externally threaded surface 103 (fig. 4), while the drinking portion 111 of the outer bottle housing 110 has a corresponding internally threaded surface 105 (fig. 3). The user can screw or unscrew the upper cap 102 into or out of the drinking portion 111 of the outer bottle case 110 by fitting the male screw surface 103 and the female screw surface 105 in a rotating manner. Wherein, the external thread surface 103 of the upper cover 102 forms an external diameter smaller than the internal diameter of the internal thread surface 105 of the drinking part 111.

The bottom cover 106 covers the assembly portion 113 (fig. 5) of the partition chute 130 and the outer bottle case 110 from below, and the upper side of the bottom cover 106 and the lower side of the partition chute 130 together define an air supply space SP 2. The bottom cap 106 is detachably connected to the assembling portion 113 of the outer bottle case 110. The bottom cover 106 and the partition groove body 130 can close the air supply space SP2 by the combination of the bottom cover 106 and the outer bottle housing 110. In the present embodiment, the volume of the gas supply space SP2 is smaller than the volume of the liquid storage space SP 1. The bottom cap 106 of the present embodiment is also screwed to the assembly portion 113 of the outer bottle shell 110. The bottom cap 106 and the outer bottle shell 110 can be tightly combined by using a material with a large friction force, such as rubber (not shown). The user can rotate the bottom cap 106 into or out of the assembly portion 113 of the outer bottle shell 110.

When the bottom cap 106 is coupled to the outer bottle case 110, the separation groove 130 is clamped therein, and the separation groove 130 can fix the position of the air supply device 150 in the air supply space SP2, preventing the air supply device 150 from being displaced in the air supply space SP 2.

The air supply device 150 is disposed in the air supply space SP2 and includes an air bottle 152 and a control air valve 154. The gas cylinder 152 includes a gas cylinder outlet 152b, and the gas cylinder 152 is placed in the gas cylinder groove 134 with the gas cylinder outlet 152b facing downward. Here, the downward direction means a direction in which the gas cylinder gas outlet port 152b faces away from the drinking portion 111 toward the bottom cover 106. In this embodiment, the gas cylinder 152 is filled with compressed liquid carbon dioxide.

When the bottom cap 106 is coupled to the outer cylinder housing 110, the separation housing 130 is clamped therein, the cylinder groove 134 fixes the position of the cylinder 152, and the valve groove 132 fixes the position of the control valve 154, thereby preventing the displacement of the cylinder 152 and the control valve 154 in the gas supply space SP 2.

The control valve 154 is disposed in the valve slot 132 for releasing the gas in the gas cylinder 152, for example, only a certain flow of gas is passed in each operation.

As shown in fig. 3, 6 and 7, the control valve 154 includes a one-way valve 156 and a valve body 160. The one-way gas valve 156 is disposed on the connection hole 132a (fig. 3) of the gas valve groove 132 to selectively allow the gas in the gas cylinder 152 to flow to the liquid storage space SP1 through the control gas valve 154. The one-way air valve 156 is disposed at the bottom of the liquid storage space SP1 and is connected to the liquid storage space SP1 and the air supply space SP2 (fig. 3). In the present embodiment, the one-way air valve 156 is, for example, a check valve, and is connected to the air outlet of the control air valve 154 so as to allow the air from the air supply space SP2 to flow to the liquid storage space SP1, and so that the liquid in the liquid storage space SP1 does not flow to the air supply space SP 2.

The valve body 160 is disposed in the valve groove 132, and the control valve 154 is fixed in the valve groove 132 by the shape of the valve body 160 matching the shape of the valve groove 132 (fig. 3, 6, and 7). In the valve body 160, the valve body 160 is shaped to define an inlet conduit 161, an outlet conduit 162, and a component chamber 163 (fig. 7). The inlet of the inlet line 161 is defined as a gas valve inlet 161a connected to a gas cylinder outlet 152 b. The outlet of the outlet pipe 162 is defined as an air valve outlet 162b, which is connected to the connecting hole 132a of the air valve groove 132 and the one-way air valve 156, and further connected to the liquid storage space SP1 (fig. 3).

As shown in fig. 7, the control valve 154 further includes a spring 155, a movable member 157, and a control button 158 in the assembly chamber 163 from top to bottom in the axial direction. In the present embodiment, the control button 158 is exemplified by a direct-press type. The control button 158 extends axially downward from the valve groove 132 to the outside of the control valve 154, and the movable member 157 is disposed in the valve body 160 to move linearly in the axial direction. An air duct 159 is defined inside the movable element 157, and the air duct 159 radially penetrates the movable element 157 to connect the air inlet duct 161 and the air outlet duct 162 when the control button 158 is pressed.

In addition, the control valve 154 further includes an upper ring 164, a movable ring 165 and a lower ring 166, all of which are sleeved outside the movable member 157 and located between the movable member 157 and the valve body 160 for gas sealing, for example, to prevent the gas in the gas cylinder 152 from leaking out from the periphery of the control button 158. Axially from top to bottom are a spring 155, an air inlet duct 161, an upper ring 164, an air outlet duct 162, a movable ring 165, an air outlet duct 159, a lower ring 166 and a control button 158, respectively, depending on the relative positions of the components of the control valve 154.

When the control button 158 is not activated, the gas in the gas cylinder 152 is connected to the gas valve inlet 161a and the gas inlet pipe 161 through the gas cylinder outlet 152b, and the movable member 157 seals the gas in the gas cylinder 152 and the gas inlet pipe 161. When the control button 158 is actuated, for example, when the control button 158 is pressed, the high-pressure gas in the gas cylinder 152 passes through the gas cylinder outlet 152b, the gas valve inlet 161a, the gas inlet pipe 161, the gas guide pipe 159 of the movable member 157, the gas outlet pipe 162, the gas valve outlet 162b and the one-way gas valve 156, and reaches the liquid storage space SP 1.

When assembling or replacing the gas cylinder 152, the user can first remove the bottom cap 106 from the outer cylinder housing 110, remove the components such as the control valve 154 and the gas cylinder 152 from the outer cylinder housing 110, and install a new gas cylinder 152 and control valve 154. In this embodiment, the outer bottle shell 110, the partition trough 130, the upper cover 102, the bottom cover 106, the air supply device 150, and other components can be detached for cleaning or replacement. In other embodiments, the outer bottle housing 110 and the partition groove 130 may be fixed to each other.

In actual use, the liquid storage space SP1 is generally used to store liquid such as water, fruit juice, tea or alcoholic beverage. After the upper cover 102 is connected with the outer bottle shell 110 to seal the liquid storage space SP1, when carbon dioxide in the gas bottle 152 enters the liquid storage space SP1 through the one-way gas valve 156, the carbon dioxide can be mixed with liquid in the liquid storage space SP1 to be dissolved to produce bubble drink.

The portable bubble water bottle 100 of the present invention may also have other structures, for example, the assembly of the upper cover 102, the bottom cover 106 and the outer bottle shell 110 may be by a combination of pivot, snap or lock. Referring to fig. 8 to 11 together, fig. 8 is a side view of a portable bubble water bottle 200 according to a second embodiment of the present invention, fig. 9 is a front view of the portable bubble water bottle 200 according to the second embodiment of the present invention, fig. 10 is a bottom view of an inner portion of a top cover 202 of the portable bubble water bottle 200 according to the second embodiment of the present invention, and fig. 11 is a bottom view of the portable bubble water bottle 200 according to the second embodiment of the present invention. The main difference between the second embodiment and the first embodiment is that the upper cap 202, the bottom cap 206 and the outer bottle shell 210 of the second embodiment are assembled and combined by pin joint and snap joint.

As shown in fig. 8 to 11, the upper lid 202 and the outer bottle shell 210 according to the second embodiment of the present invention are coupled by a first pivot component 271, and are engaged and closed by a first engaging component 273, so as to open the elastic lid. On the other hand, the bottom lid 206 and the assembling portion 213 of the outer bottle housing 210 are coupled by the second pivot joint 272, and are engaged and closed and the elastic lid is opened by the second engaging member 274 (fig. 9 and 11). The top lid 202 can rotate relative to the outer bottle housing 210 with the first pivot element 271 as the axis, and the bottom lid 206 can rotate relative to the outer bottle housing 210 with the second pivot element 272 as the axis. Thus, the top cover 202 and the bottom cover 206 can be opened and closed easily without losing.

In addition, the control valve 154 of the present invention may have other configurations. Referring to fig. 12, fig. 12 is a schematic cross-sectional view of a portable bubble water bottle 300 according to a third embodiment of the present invention. The main difference between the third embodiment and the previous two embodiments is that the control valve 354 of the third embodiment has a different design and the control button 358 extends radially outward from the valve groove 132 to the outside of the outer bottle housing 310.

As shown in fig. 12, the control air valve 354 includes an air valve inlet 361a, an air valve outlet 362b, an air inlet duct 361, an air outlet duct 362, a one-way air valve 156, a control button 358, a valve body 360, a movable member 357 and a ring 367. The gas cylinder outlet port 152b is connected to the gas valve inlet port 361a, and the gas valve outlet port 362b is connected to the liquid storage space SP1 through the connection hole 132a of the gas valve groove 132.

The control button 358 extends radially outward from the air valve slot 132 to the outside of the outer bottle housing 310. The valve body 360 is disposed in the valve spool 132, and the movable member 357 is disposed in the valve body 360 to radially linearly move. The ring 367 is disposed between the movable member 357 and the valve body 360 for sealing the gas therein, so as to prevent the gas in the gas cylinder 152 from leaking out of the periphery of the control button 358.

When the control button 358 is not actuated, the gas in the gas cylinder 152 is connected to the gas valve inlet 361a and the gas inlet conduit 361 through the gas cylinder outlet 152b, and the movable member 357 seals the gas in the gas cylinder 152 and the gas inlet conduit 361. When the control button 358 is actuated, for example, when the control button 358 is pressed, the high-pressure gas in the gas cylinder 152 reaches the liquid storage space SP1 through the gas cylinder outlet 152b, the gas valve inlet 361a, the gas inlet conduit 361, the movable member 357, the gas outlet conduit 362, the gas valve outlet 362b and the one-way gas valve 156.

The present invention has the following advantages. Firstly, the air valve air outlets of the portable bubble water bottle are connected to the connecting hole at the bottom of the liquid storage space, so that gas and liquid can be mixed from the bottom of the liquid storage space. By utilizing the upward buoyancy force applied to the bubbles, the liquid in the whole liquid storage space is fully mixed and contacted with the gas, and the gas dissolving effect is greatly improved. Secondly, because the portable bubble water bottle is placed in the gas bottle groove in a mode that the gas outlet of the gas bottle faces downwards, the whole portable bubble water bottle can be utilized to strengthen the gas supply space for covering and containing the gas bottle, and the safety of the bubble water bottle in use can be improved. In addition, the upper cover and the bottom cover can be detachably connected with the outer bottle shell in a screwing, pivoting, clamping and other modes, so that the bottle opener can be easily opened and closed and is not easy to lose.

In addition, the invention utilizes the design of the control gas valve to mix gas and liquid in batches without exhausting all the gas in the gas cylinder at one time. Therefore, the single air bottle can be used for multiple times by one portable bubble water bottle. Taking a portable bubble water bottle with the water capacity of 600 milliliters as an example, one gas bottle can provide 1800 milliliters of liquid to achieve a sufficient gas dissolving effect, so that one gas bottle can be filled with water and mixed for 3 times. Therefore, the water intake required by an adult in one day can be provided by only carrying one portable bubble water bottle, and the problems that 1800 ml of bubble water needs to be mixed for carrying out once, bubbles in water continuously dissipate and disappear along with uncovering during drinking and the load weight is overlarge are solved. In addition, the gas release condition can be manually controlled by a user, and the user can also automatically adjust the gas-liquid mixing amount according to the self needs or preferences, so that the customized effect is achieved.

In conclusion, the invention can greatly improve the air dissolving effect, increase the safety of the bubble water bottle in use, easily operate, dissolve air in sections, be easy to carry, reduce the air dissipation speed and achieve the customized effect.

The foregoing is by way of example only, and not limiting. Any equivalent modifications or variations without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
