Description

Technical Field

[0001] The utility model relates to the technical field of red wine suction devices, and more specifically, to a two-in-one extraction device for extracting air and wine. Background Art

[0002] In order to facilitate the pouring of red wine, a wine extraction device is usually installed at the mouth of the wine bottle, which can be used to easily extract the red wine in the bottle; and when the red wine cannot be finished in one go after opening, the air in the wine bottle needs to be extracted to form a vacuum environment in the wine bottle, so as to extend the shelf life of the red wine and enable the red wine to maintain good taste and quality during storage. In order to meet both needs of users at the same time, it is necessary to combine the wine extraction device with the vacuum extraction device. Currently, there are two products on the market that have this combination of wine extraction and sealing: one is that the product is integrated, and the product is directly inserted into the wine bottle, and the switching mode is selected by pressing the button, or the vacuum extraction mode is directly entered after the red wine is extracted. When sealed and stored, the product must remain at the bottle mouth; due to the large size of this product, the red wine will occupy a large space during storage, causing inconvenience to the user; the other is that the product comes with an additional wine cork, but the wine cork is separately placed externally during the vacuum extraction process. During the vacuum extraction process, the wine cork and the product are separated. After the wine bottle is vacuumed, the wine cork is removed and directly inserted into the wine bottle for sealing. This product will cause air to re-enter the wine bottle during the switching process between the vacuum extraction component and the wine cork, and the vacuum state of the wine bottle cannot be truly achieved, which is not conducive to the sealed storage of red wine. Utility Model Content

[0003] The purpose of the utility model is to overcome the problem that an extraction device with both wine extraction and vacuum extraction functions cannot be removed after the wine bottle is vacuumed, so that too much storage space is occupied, or the extraction device replaces the wine cork and installs it in the bottle mouth after vacuuming, which affects the sealing effect during the component switching process. A two-in-one extraction device for air extraction and wine extraction is provided, which can overcome the above two problems, not only does it not occupy too much storage space during the storage process of red wine, but also ensures that the red wine has a better sealing and preservation effect.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A two-in-one extraction device for air extraction and wine extraction comprises a shell, a wine extraction mechanism, an air extraction mechanism, an extraction switch, a switching mechanism, a wine stopper, and a controller. The wine extraction mechanism, the air extraction mechanism, and the controller are all mounted in the shell. The extraction switch is also mounted in the shell and partially exposed from the shell. The switching mechanism is detachably mounted at the bottom of the shell. An extraction channel is provided in the shell. The wine stopper is provided at the bottom of the switching mechanism. The wine extraction mechanism, the air extraction mechanism, and the wine stopper are all connected to the extraction channel. The wine extraction mechanism, the air extraction mechanism, the switching mechanism, and the extraction switch are all electrically connected to the controller. When the switching mechanism and the wine stopper are not installed, the extraction device defaults to the wine extraction mode. When the switching mechanism and the wine stopper are installed, the extraction device switches to the air extraction mode.

[0006] The extraction device of the utility model is an electric product with a combination of wine extraction and wine bottle vacuuming functions, and a switching mechanism is used as a switch between two modes to achieve functional conversion. Remove the switching mechanism and the wine cork, the product defaults to the wine extraction mode, press the extraction switch, the wine extraction mechanism works, and the red wine is extracted; install the switching mechanism and the wine cork, the product switches to the air extraction mode, the consumer first inserts the wine cork into the mouth of the wine bottle, and then aligns the switching mechanism with the wine cork interface, presses the extraction switch, the air extraction mechanism works, and the gas in the wine bottle is extracted to achieve a vacuum state in the bottle and then achieve sealing. After the air extraction is completed, the shell is removed, and the wine cork is retained on the wine bottle to seal. The inventive point of the utility model lies in this structure that realizes the combination of wine extraction and vacuum extraction functions by replacing parts. Within the scope of cognition of those skilled in the art, the extraction device of the utility model can be applied to the extraction and sealing of red wine, and can also be applied to the extraction and vacuum extraction of other alcoholic or non-alcoholic bottled liquids.

[0007] Furthermore, the wine extraction mechanism includes a wine extraction pump, a wine nozzle, and a wine extraction tube. One end of the wine nozzle is connected to the shell, and the other end protrudes from the shell. The wine extraction pump is installed in the shell, and the wine extraction tube is detachably connected to the bottom of the shell. The wine extraction pump, the wine extraction tube, and the wine nozzle are all connected to the extraction channel. In the wine extraction mode, the consumer plugs in the wine extraction tube, inserts the shell into the wine bottle, presses the extraction switch, and the wine extraction pump works, and the red wine in the wine bottle is extracted through the wine extraction tube and the wine nozzle. The wine extraction tube is detachably connected to the bottom of the shell, which can facilitate the separation of the wine extraction tube and the shell, so that when the wine extraction mode is switched to the air extraction mode, the vacuum extraction function of the wine bottle can be realized.

[0008] Furthermore, the end of the wine spout away from the housing is tilted downward, so that it is convenient to pour the red wine from the wine spout.

[0009] Furthermore, the wine extraction tube is a retractable structure. The wine extraction tube with a retractable structure can expand the application scope of the extraction device of the utility model, especially for wine bottles of different depths, the length of the wine extraction tube can be adaptively adjusted to facilitate the wine extraction function. Within the scope of knowledge of those skilled in the art, the wine extraction tube can also be a conventional non-retractable structure. Preferably, the wine extraction tube is made of silicone material.

[0010] Furthermore, the air extraction mechanism is an air pump, which is used to extract air from the wine bottle to ensure that the wine bottle is in a vacuum state, which is convenient for sealed storage of red wine.

[0011] Furthermore, the switching mechanism includes a support frame, a passive touch part and an active touch part. The passive touch part is installed at the bottom of the shell and electrically connected to the controller. The active touch part is installed on the support frame. One end of the support frame is detachably connected to the shell, and the other end is detachably connected to the wine stopper. When the support frame is connected to the shell, the active touch part can trigger the passive touch part to send a signal. The support frame is used to install the active touch part, and at the same time, the switching mechanism is convenient for detachable connection with the shell or the wine stopper. The active touch part is actively triggered, so that the passive touch part receives the trigger signal and then transmits the signal to the controller, so that the controller can switch between the wine extraction mode and the air extraction mode.

[0012] Furthermore, the active touch part is a magnet, and the passive touch part is a Hall sensor; or the active touch part is a convex column, and the passive touch part is a touch switch; or the active touch part is a pin, and the passive touch part is a conductive pin shaft. The Hall sensor can be triggered to send a signal to the controller to switch the mode by the magnet touching it; similarly, the active touch part can be other structures for triggering, and the passive touch part is a structure that can send a signal after being triggered by the active touch part. The triggering principle can be various, including but not limited to the several methods listed above.

[0013] Furthermore, the wine stopper includes a stopper sleeve and a stopper, an airway is provided inside the stopper sleeve, and the stopper sleeve is detachably connected to the bottom of the switching mechanism; the stopper is movably installed in the stopper sleeve and can open the airway to make it communicate with the extraction channel or close the airway. The inside of the stopper sleeve cooperates with the stopper, and the stopper is used at different positions of the stopper sleeve to control the opening or closing of the airway; the outside of the stopper sleeve is used to cooperate with the wine bottle to achieve the sealing between the outer wall of the stopper sleeve and the inner wall of the wine bottle mouth.

[0014] Furthermore, the circumferential outer wall of the stopper sleeve is provided with a plurality of protrusions, which can increase the friction between the stopper sleeve and the mouth of the wine bottle and improve the sealing effect of the stopper.

[0015] Furthermore, the wine pump is a suction pump or an air injection pump. When the wine pump is a suction pump, the red wine in the wine bottle can be extracted by the principle of suction; when the wine pump is an air injection pump, air can be injected into the wine bottle to press the red wine out of the wine pipe and then out of the wine spout.

[0016] The beneficial effects of the utility model are:

[0017] (1) It has the functions of extracting wine and vacuuming the wine bottle at the same time. After the vacuuming is completed, the main part of the extraction device can be removed, leaving only the wine cork sealed on the wine bottle, which greatly saves the storage space of the wine.

[0018] (2) The switching between the wine extraction mode and the gas extraction mode can be realized by using the switching mechanism in coordination with the controller. In the wine extraction mode, there is no need to install the switching mechanism; in the gas extraction mode, the switching mechanism and the wine cork need to be installed, and the switching between the two modes is very convenient; moreover, during the gas extraction process, the wine cork is always kept at the mouth of the wine bottle. During the gas extraction process, the airway in the wine cork is opened, and after the gas extraction is completed, the airway in the wine cork is closed. The whole process keeps the wine bottle in a vacuum state, which has a good sealing effect.

[0019] (3) The switching mechanism triggers a signal when the active touch part contacts the passive touch part, thereby transmitting the mode switching signal to the controller. The structure and triggering principle of the active touch part and the passive touch part can be various, including but not limited to being implemented in the form of sensors or mechanical buttons.

[0037] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0038] Example 1

[0039] like Figures 1 to 9 The figure shows an embodiment 1 of a two-in-one extraction device for air extraction and wine extraction of the utility model, comprising a shell 1, a wine extraction mechanism 2, an air extraction mechanism 3, an extraction switch 4, a switching mechanism 5, a wine cork 6, and a controller 7. The wine extraction mechanism 2, the air extraction mechanism 3, and the controller 7 are all installed in the shell 1, the extraction switch 4 is also installed in the shell 1 and is partially exposed from the shell 1, the switching mechanism 5 is detachably installed at the bottom of the shell 1, an extraction channel 11 is provided in the shell 1, the wine cork 6 is arranged at the bottom of the switching mechanism 5, the wine extraction mechanism 2, the air extraction mechanism 3, and the wine cork 6 are all connected with the extraction channel 11, and the wine extraction mechanism 2, the air extraction mechanism 3, the switching mechanism 5, and the extraction switch 4 are all electrically connected with the controller 7; when the switching mechanism 5 and the wine cork 6 are not installed, the extraction device defaults to the wine extraction mode; when the switching mechanism 5 and the wine cork 6 are installed, the extraction device switches to the air extraction mode.

[0040] The housing 1 is used to provide installation space for the wine extraction mechanism 2 and the air extraction mechanism 3, and integrate various components therein; the wine extraction mechanism 2 is used to extract red wine for easy pouring out; the air extraction mechanism 3 is used to extract air from the wine bottle 8, so that the wine bottle 8 reaches a vacuum state, which is conducive to short-term storage of red wine when it cannot be drunk all at once after opening, so that the red wine can always maintain good taste and quality during storage. The extraction switch 4 is used to control the opening or closing of the wine extraction mechanism 2 or the air extraction mechanism 3; the switching mechanism 5 is used to switch between the wine extraction mode and the air extraction mode. In fact, the switching mechanism 5 can realize the triggering of the signal, and the controller 7 is used to switch the control mode. When the controller 7 receives the switching signal of the switching mechanism 5, it switches between the wine extraction mode and the air extraction mode, and controls the wine extraction mechanism 2 or the air extraction mechanism 3 to be connected with the extraction channel 11.

[0041] Specifically, the air extraction mechanism 3 is an air extraction pump. The wine extraction mechanism 2 includes a wine extraction pump 21, a wine spout 22, and a wine extraction pipe 23. One end of the wine spout 22 is connected to the housing 1, and the other end protrudes from the housing 1. The wine extraction pump 21 is installed in the housing 1, and the wine extraction pipe 23 is detachably connected to the bottom of the housing 1. The wine extraction pump 21, the wine extraction pipe 23, and the wine spout 22 are all connected to the extraction channel 11. Further, the wine extraction pump 21 is provided with a wine pump inlet 211 and a wine pump outlet 212. After the red wine enters the wine pump inlet 211 from the wine extraction pipe 23, it passes through the wine pump outlet 212 and flows out from the wine spout 22. The end of the wine spout 22 away from the housing 1 is tilted downward. Preferably, the wine extraction pipe 23 is a retractable structure. In the wine extraction mode, the consumer plugs in the wine extraction pipe 23, inserts the housing 1 into the wine bottle 8, presses the extraction switch 4, and the wine extraction pump 21 works, and the red wine in the wine bottle 8 is extracted through the wine extraction pipe 23 and the wine spout 22. The wine extraction pipe 23 is detachably connected to the bottom of the housing 1, which can facilitate the separation of the wine extraction pipe 23 from the housing 1, so that when the wine extraction mode is switched to the air extraction mode, the wine bottle 8 can be easily vacuumed. The wine extraction pipe 23 with a retractable structure can expand the scope of application of the extraction device of the utility model, especially for wine bottles 8 of different depths, the length of the wine extraction pipe 23 can be adaptively adjusted to facilitate the wine extraction function. Specifically, the wine extraction pipe 23 includes at least a first section and a second section that are mutually sleeved. By inserting the first section into the second section, the length of the wine extraction pipe 23 can be shortened as a whole, and the first section is pulled out of the second section and fixed at the connected end, so that the length of the wine extraction pipe 23 is the superposition of the length of the first section and the second section, which can greatly expand the length of the wine extraction pipe 23; within the scope of knowledge of those skilled in the art, the wine extraction pipe 23 can also have more sleeved section structures, which are sleeved in sequence, and the wine extraction pipe 23 is extended or shortened according to the length of the wine bottle 8 to adapt to the length of the wine bottle 8, so as to facilitate the extraction of wine.

[0042] In addition, the switching mechanism 5 includes a support frame 51, a passive touch part 53 and an active touch part 52. The passive touch part 53 is installed at the bottom of the housing 1 and is electrically connected to the controller 7. The active touch part 52 is installed on the support frame 51. One end of the support frame 51 is detachably connected to the housing 1, and the other end is detachably connected to the wine stopper 6. When the support frame 51 is connected to the housing 1, the active touch part 52 can trigger the passive touch part 53 to send a signal. The support frame 51 is used to install the active touch part 52, and at the same time, the switching mechanism 5 is convenient for detachable connection with the housing 1 or the wine stopper 6. The active touch part 52 is actively triggered, so that the passive touch part 53 receives the trigger signal and then transmits the signal to the controller 7, so that the controller 7 can switch between the wine extraction mode and the air extraction mode.

[0043] As an improved solution of this embodiment, the active touch part 52 is a magnet 521, and the passive touch part 53 is a Hall sensor 531. The Hall sensor 531 can be triggered to send a signal to the controller 7 to switch the mode by the magnet 521 touching the Hall sensor 531.

[0044] Furthermore, the wine stopper 6 includes a stopper sleeve 61 and a stopper 62. An air passage 63 is provided inside the stopper sleeve 61. The stopper sleeve 61 is detachably connected to the bottom of the switching mechanism 5. The stopper 62 is movably installed inside the stopper sleeve 61 and can open the air passage 63 to make it communicate with the extraction channel 11 or close the air passage 63. The stopper sleeve 61 is matched with the stopper 62 inside, and the stopper 62 is used to control the opening or closing of the air passage 63 at different positions of the stopper sleeve 61. The outside of the stopper sleeve 61 is used to cooperate with the wine bottle 8 to achieve the sealing between the outer wall of the stopper sleeve 61 and the inner wall of the mouth of the wine bottle 8. Preferably, a plurality of protrusions 64 are provided on the circumferential outer wall of the stopper sleeve 61. The setting of the protrusions 64 can increase the friction between the stopper sleeve 61 and the mouth of the wine bottle 8, and improve the sealing effect of the stopper 62.

[0045] As an improved solution of the present embodiment, the wine pump 21 is a suction pump. When the wine pump 21 adopts a suction pump, the red wine in the wine bottle 8 can be extracted by the principle of suction.

[0046] Example 2

[0047] like Fig.10 The second embodiment of the utility model is a two-in-one extraction device for extracting gas and wine. This embodiment is similar to the first embodiment, except that the active touch part 52 is a convex column 522, and the passive touch part 53 is a touch switch 532. The convex column 522 touches the touch switch 532 to transmit a mode switching signal to the controller 7, thereby realizing the switching between the wine extraction mode and the gas extraction mode.

[0048] Example 3

[0049] like Fig.11 The third embodiment of the utility model is a two-in-one extraction device for extracting gas and wine. This embodiment is similar to the first embodiment, except that the active touch part 52 is a pin 523, and the passive touch part 53 is a conductive pin shaft 533. The pin 523 touches the conductive pin shaft 533 to generate and transmit a mode switching signal to the controller 7, thereby realizing the switching between the wine extraction mode and the gas extraction mode.

[0050] Example 4

[0051] like Fig.12 and Fig.13 The fourth embodiment of a two-in-one extraction device for extracting air and wine is shown. This embodiment is similar to the first embodiment, except that the wine extraction pump 21 is an air injection pump. In this embodiment, an air inlet 12 needs to be added to the bottom of the housing 1 to achieve the air injection function; when the wine extraction pump 21 is an air injection pump, by injecting air into the wine bottle 8, the red wine can be pressed through the wine extraction pipe 23 and then flow out from the wine spout 22.

[0052] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here.
