Description

Drinking device Technical Field

[0001] The present invention relates to the field of daily necessities, in particular to a drinking device. Background Art

[0002] Currently, when people use cups or bottles to drink water, they generally only pour in plain water. If they need to drink flavored water, they often add corresponding flavorings to the plain water. Once these flavorings are mixed with the plain water and enter the digestive system, not only can the chemical components such as aromatic substances or stabilizers in the drink be absorbed by the body, causing potential harm, but the sugar content can also cause the body to consume excessive calories, which is not good for health. Chinese invention patent No. CN 113301832 A discloses a drinking device that eliminates the need to add flavorings to the water. Instead, it utilizes the retronasal sense of smell to perceive odors. The odor in the air and the odor of the water after entering the mouth trigger the olfactory tissue to create the illusion that the water is drinking a certain flavor, thereby enhancing the pleasure of drinking water. The following structure is disclosed in the revised text of the claims in response to the examination opinion:

[0003] A drinking device comprises: a storage container for drinking liquid; a head that can be fastened to the storage container and has a mouth end and a stopper; a replaceable fragrance container, air can flow through the fragrance container, and the fragrance container can be fastened to the head, when the fragrance container is pushed upward into an operating position, the stopper limits the axial movement of the fragrance container; and a drinking straw, which is fixed in the head, the drinking straw comprising: a delivery channel for drinking liquid, the delivery channel extending from the storage container toward the mouth end of the head; and an air channel for delivering scented air, the air channel extending from the fragrance container toward the mouth end of the head, wherein the stopper has an inwardly flexible structure through a circumferential cavity for replacing the fragrance container.

[0004] However, in this structure, to reach the operating position, the fragrance container must be moved upward toward the mouth end so that the top side of the fragrance container abuts the stopper. Furthermore, to allow replacement of the fragrance container, the stopper must be configured with an inwardly flexible structure through the circumferential cavity to ensure that the fragrance can easily pass over the stopper and be disengaged while being continuously forced upward. Similarly, the reverse operation must be performed to replace the fragrance container. Consequently, this structure is not only complex and inconvenient to use, but also cumbersome to produce, resulting in high manufacturing costs. Furthermore, the fact that the fragrance container is mounted on the drinking straw necessitates a hollowed-out portion in the middle of the fragrance container, which not only limits the capacity of the fragrance container but also its overall shape.

[0035] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings:

[0037] A drinking device, as shown in Figures 1 to 15, includes a cover body 1 and a bottle body 2, the bottle body 2 is used to hold drinking water, the cover body 1 can be covered on the bottle body 2, and the covering method of the two is preferably screwed together, the cover body 1 is provided with a base cover 11, and also includes a spice box 111, the spice box 111 is provided with an air inlet 1111 and an air outlet 1112, a spice cavity 113 and a suction nozzle 112 are adjacently provided on the base cover 11, the spice cavity 113 is used to accommodate the spice box 111, since there is no need to consider the shape of the suction nozzle 112 The spice chamber 113 can be set to a variety of shapes, such as the middle part is completely hollowed out, the main body is hollowed out or fully enclosed. For ease of understanding, the hollowing here refers to the circular space in the middle of the annular spice box mentioned in the comparative document in the background technology. In order to increase the spice accommodating space and reduce production materials and production difficulty, the spice chamber 113 is preferably set to a groove with only one side wall and a bottom wall. The spice box 111 is set to have a through cavity inside and a closed box body with only one side wall, a bottom wall and a top wall, that is, a fully enclosed shape.

[0038] The main body of the suction nozzle piece 112 is provided with a water flow channel 1121 in the longitudinal direction and an air flow channel 1122 in the transverse direction. The air flow channel 1122 is connected to the front side wall of the fragrance chamber 113. The relative position of the fragrance box 111 changes to connect or close the air outlet 1112 to the air flow channel 1122. The relative position here refers to the relative position of the spice box 111 and the suction nozzle piece 112. Either the spice box 111 or the suction nozzle piece 112 can be moved, or both can be moved. The movement of the relative position is limited by the mutual limitation of the first ridge 1113 provided on the spice box 111 and the second ridge 1131 provided on the fragrance chamber 113. When the first ridge 1113 and the second ridge 1131 are against the limit, the air outlet 1112 is connected to the air flow channel 1122.

[0039] In this embodiment, the fragrance box 111 is preferably moved to change the relative position. The fragrance box 111 can be moved in a variety of ways such as up and down, left and right, front and back, or rotation to change the relative position.

[0040] In the first embodiment, the fragrance box 111 is movable up and down, and the first ridge 1113 is provided on the side wall of the fragrance box 111, and the second ridge 1131 is provided on the side wall of the fragrance chamber 113. The shapes of the fragrance chamber 113 and the fragrance box 111 within the range of the base cover 11 can be customized to various geometric shapes such as square and rectangle. In this embodiment, the fragrance chamber 113 and the fragrance box 111 are preferably both elliptical cylinders. When in use, the fragrance box 111 is moved upward until the first ridge 1113 and the second ridge 1131 abut against each other. At this time, the air outlet 1112 is connected with the air flow channel 1122, and the smell in the fragrance box 111 can enter the water flow channel 1121 and enter the mouth together with the inhaled water. After the smell reaches the olfactory cells behind the nose, the drinker feels that the water he drinks has a drink with this smell. When the fragrance box 111 moves downward, the air outlet 1112 is no longer connected with the air flow channel 1122, and the water the drinker drinks does not have the smell in the fragrance box 111.

[0041] In the second embodiment, the spice box 111 is rotated and moved. To facilitate rotation, the spice chamber 113 and the spice box 111 are both configured as cylindrical shapes. The first ridge 1113 is provided on the bottom wall of the spice box 111, and the second ridge 1131 is provided on the bottom wall of the spice chamber 113. The spice box 111 can be rotated horizontally so that the first ridge 1113 abuts against or moves away from the second ridge 1131. When in use, the spice box 111 is rotated horizontally until the first ridge 1113 and the second ridge 1131 abut against each other. At this time, the air outlet 1112 is connected to the air flow channel 1122, and the smell in the spice box 111 can enter the water flow channel 1121 and enter the mouth together with the inhaled water. After the smell reaches the olfactory cells behind the nose, the drinker feels that the drinking water has this kind of drink. When the spice box 111 rotates in the opposite direction, the air outlet 1112 is no longer connected to the air flow channel 1122, and the water the drinker drinks does not have the taste of the spice box 111.

[0042] In this embodiment, the upper part of the suction nozzle 112 is arranged on the upper side of the base cover 11 for mouth contact, and the lower part is arranged on the lower side of the base cover 11 for connecting to the straw 21 in the bottle body 2. The outer surface of the upper part of the suction nozzle 112 is smooth. Compared with the straw in the background technology, the smooth outer surface can provide the user with a longer mouth contact space and a better sucking experience.

[0043] In this embodiment, a drinking device further includes a top cover 12 , which is provided with an upwardly protruding suction nozzle cavity 121 , the suction nozzle cavity 121 is used to accommodate the suction nozzle member 112 , and the top cover 12 is axially connected to the base cover 11 and can be opened and closed. The opening and closing method adopted in this embodiment is that a protruding connecting piece 116 is provided at the rear end of the base cover 11, and the connecting piece 116 is provided with a first torsion spring cavity 1161, and a second torsion spring cavity 124 is provided at the rear end of the top cover 12. The second pin shaft 106 connects the connecting piece 116 and the rear end of the top cover 12, and a torsion spring 107 is sleeved on the second pin shaft 106. One end of the torsion spring 107 is fixed in the first torsion spring cavity 1161 and the other end is fixed in the second torsion spring cavity 124. In the default state, the elasticity of the torsion spring 107 makes the top cover 12 move away from the base cover 11. Preferably, the angle between the top cover 12 and the base cover 11 is 90 degrees to 180 degrees, which is convenient for the user to use the straw 21 with his mouth. The top cover 12 is pressed by external force, causing the torsion spring 107 to deform and finally buckle on the base cover 11.

[0044] In order to lock the buckling of the top cover 12 and the base cover 11, in this embodiment, a locking assembly 114 is provided between the two to lock their opening and closing. The locking assembly 114 includes a button groove 1142 provided on the base cover 11. The button groove 1142 is used to place a button 1141. The button groove 1142 and the button 1141 are preferably set to a square shape. The front side of the button 1141 is set to a pressing surface 101, the left and right sides are provided with a through strip groove 102, and the upper side is provided with a first limit member 103. The bottom wall of 1142 is provided with a mounting groove 11421, and the rear side of the button 1141 is provided with a mounting column 104. The mounting groove 11421 and the mounting column 104 are arranged relative to each other and are installed with an elastic member 109. The elastic member 109 is preferably a spring or a silicone elastic member. The button 1141 is fixed in the button groove 1142 through the first pin shaft 1010 through the strip groove 102. The elastic member 109 pushes the button 1141 so that the first pin shaft 1010 is relatively located at the rear end of the strip groove 102 and can produce elastic deformation after being subjected to external force. The relative position moves toward the front end, that is, after pressing the pressing surface 101, the button 1141 overcomes the tension of the elastic member 109 and moves backward, and the strip groove 102 moves backward relatively. The locking assembly 114 also includes a second limiting member 123 provided on the top cover 12, the first limiting member 103 is provided with a first inclined surface 1031 and a first plane 1032, and the second limiting member 123 is provided with a second inclined surface 1231 and a second plane 1232. After the second inclined surface 1231 contacts the first inclined surface 1031 and moves, the second plane 1232 32 and the first plane 1032 form a locking limit; the locking assembly 114 also includes a fastener 1143 installed on both sides of the first pin shaft 1010 and a pressure-bearing surface 122 set on the front of the top cover 12, the inner edge shape of the fastener 1143 is the same as the outer surface shape of the pressure-bearing surface 122, and a limiting protrusion 1221 is set on the top surface of the fastener 1143. The fastener 1143 is axially connected to both ends of the first pin shaft 1010 and can be rotatably sleeved and engaged with the limiting protrusion 1221 on the pressure-bearing surface 122 to fasten the base cover 11 and the top cover 12. As shown in Figures 13 and 14, when working, the top cover 12 is pressed downward, and the second limit member 123 and the first limit member 103 begin to contact. Under the interaction force, the second inclined surface 1231 drives the first inclined surface 1031 to move, so that the button 1141 moves backward and compresses the elastic member 109 to produce elastic deformation until the second inclined surface 1231 is out of contact with the first inclined surface 1031. At this time, the first inclined surface 1031 loses pressure, and the elastic member 109 restores the tension to push the button 1141 forward so that the second plane 1232 and the first plane 1032 contact to form a limit, thereby achieving locking. When the top cover 12 needs to be opened, press the button 1141 to disengage the second plane 1232 and the first plane 1032. Then, under the action of the torsion spring 107, the top cover 12 bounces open and drinking can be done.

[0045] In the locked state, to further ensure the locking effect, the fastener 1143 can be rotated upward to the position of the limiting protrusion 1221 to achieve contact with the pressure-bearing surface 122. In this embodiment, as shown in Figure 1, handles 108 can be further provided at both ends of the second pin 106 for easy carrying.

[0046] On the basis that the top cover 12 can be buckled with the base cover 11, the air inlet 1111 can be opened on the top wall of the spice box 111, and a top plug 125 is set at the position of the top cover 12 corresponding to the air inlet 1111. When the top cover 12 is buckled on the base cover 11, the top plug 125 blocks the air inlet 1111, which can further ensure that the spices in the spice box 111 are in a sealed state when not in use and will not evaporate.

[0047] To make drinking more convenient, as shown in Figures 1, 2 and 7, the bottle body 2 includes a bending portion 22 and a main body 23. The bending portion 22 is configured to be bent at an acute angle, and the main body 23 is configured to be straight. The upper portion of the bending portion 22 is movably connected to the cover body 1, and the lower portion is connected to the main body 23. The bending portion 22 can tilt the upper connected cover body 1 towards the drinker. The bending portion 22 and the main body 23 can be integrally formed or connected separately, and the bending portion 22 and / or the main body 23 are made of plastic or metal. The integral formation of the bending portion 22 and the main body 23 can save processing costs, but the processing technology of the bending portion 22 is relatively complicated compared to the traditional straight-cylinder bottle body. Therefore, the bending portion 22 and the main body 23 can also be connected separately, thereby reducing the requirements for the processing technology of the bending portion 22. To accommodate different needs, the bottle body 2 can be made of different materials. If processing technology is not an issue, the bottle body 2 can be made of plastic to meet the needs of drinking water at room temperature, or metal to meet the needs of drinking water at insulated temperatures. If processing technology does not allow for one-piece molding, the bent portion 22 and main body 23 can be made of plastic or metal, respectively, and then connected separately, depending on the needs of drinking water at room temperature or insulated temperatures. In this embodiment, when a separate connection is used, the bent portion 22 and main body 23 can be threaded together and sealed with a sealing ring 24 in the middle to prevent leakage.

[0048] From the above description, it can be seen that the above embodiment achieves the following technical effects: the spice box and the suction mouthpiece are not connected and limited by a sleeve and a sleeve, not only the processing technology of the spice box and the suction mouthpiece is simple, but also the shape of the spice box can be customized and the capacity is larger, the surface of the suction mouthpiece is smooth and easier to use, easy to operate and low cost.

[0049] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention. The scope of protection of the present invention is determined by the appended claims.
