[0055] The holding type vacuum bottle provided by the utility model aims at solving the above technical problems of the prior art.

[0056] The technical solutions of the utility model and how the technical solutions of the utility model solve the above technical problems are described in detail below with specific examples.

[0057] The utility model embodiment provides a kind of holding type vacuum bottle product, and the structure schematic diagram of the holding type vacuum bottle product is as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 And Figure 9 It includes: including bottle body 10 and bottle nozzle component 20;Bottle body 10 one end is bottle mouth end, and bottle nozzle component 20 one end is connecting end, and one of bottle mouth end one end and connecting end is provided with clamping piece 40, and the other is provided with limiting piece 50, and limiting piece 50 at least includes circumferential limit part 53, upper limit part 51 and lower limit part 52 arranged in upper and lower;When bottle mouth end is connected with connecting end, clamping piece 40 enters between upper limit part 51 and lower limit part 52 from one end of upper limit part 51 or lower limit part 52, to limit the movement of bottle body 10 in the height direction of bottle nozzle component 20, and circumferential limit part 53 acts on clamping piece 40, to limit the rotation of bottle body 10 in the circumferential direction of bottle nozzle component 20.

[0058] Among them, it can be known that bottle body 10 is used to hold, and bottle nozzle component 20 is used to liquid outlet. The main structure of this embodiment is the connecting structure between bottle body 10 and bottle nozzle component 20. Preferably, the bottle mouth end of the top end of bottle body 10 is rotatably connected to the connecting end of the bottom end of bottle nozzle component 20.

[0059] For example, the limiting member 50 is arranged on the bottle mouth assembly 20, and the clamping member 40 is arranged on the bottle body 10. After the bottle body 10 is sleeved with the bottle mouth assembly 20, the clamping member 40 is located between the upper limiting portion 51 and the lower limiting portion 52 in the height direction of the vacuum bottle, then the bottle body 10 and the bottle mouth assembly 20 are rotated in opposite directions or one of them is rotated in a certain direction, and finally the clamping member 40 enters between the upper limiting portion 51 and the lower limiting portion 52 and interacts with the circumferential limiting portion 53. The upper limiting portion 51 and the lower limiting portion 52 limit the movement of the bottle body 10 in the axial direction of the vacuum bottle, and the circumferential limiting portion 53 limits the movement of the bottle body 10 in the circumferential direction of the vacuum bottle, so that the installation of the bottle body 10 and the bottle mouth assembly 20 is completed. For the convenience of description, the position of the bottle body 10 at this time is the locked position.

[0060] In other embodiments, the limiting member 50 is arranged on the bottle body 10, and the clamping member 40 is arranged on the bottle mouth assembly 20, which will not be repeated here.

[0061] The connection structure and mode of the bottle body 10 and the bottle mouth assembly 20 described above are simpler in structure and more convenient in connection operation than threaded connection.

[0062] Optionally, the upper limiting portion 51 includes an upper blocking strip, the lower limiting portion 52 includes a lower blocking strip, the circumferential limiting portion 53 includes a limiting protrusion 531, the limiting protrusion 531 is arranged on one side of the lower blocking strip close to the upper blocking strip, and the clamping member 40 is provided with a clamping interface 41 matched with the limiting protrusion 531 on the side close to the lower blocking strip. The clamping member 40 is inserted between the upper limiting portion 51 and the lower limiting portion 52, and the clamping interface 41 is clamped with the limiting protrusion 531.

[0063] For example, the upper blocking strip and the lower blocking strip are equal in length and arranged in parallel with each other. Alternatively, the upper blocking strip and the lower blocking strip are arranged in alignment at both ends. At this time, the limiting protrusion 531 is located at the top of the lower blocking strip, and the clamping interface 41 is located at the bottom of the clamping member 40. The limiting protrusion 531 is an arc-shaped strip, and its axis line passes through the axis line of the vacuum bottle in the height direction of the bottle mouth assembly 20. Correspondingly, the clamping interface 41 is matched with the limiting protrusion 531.

[0064] In other embodiments, the limiting protrusion 531 can be arranged at the bottom of the upper blocking strip, and the clamping interface 41 is located at the top of the clamping member 40.

[0065] Optionally, the circumferential limiting portion 53 further includes an end blocking strip 532 arranged on one end of the upper blocking strip and the lower blocking strip close to each other. And / or, a rotation stopping blocking strip 80 is further included, which limits the clamping member 40 to enter the upper limiting portion 51 and the lower limiting portion 52. When the clamping member 40 is inserted between the upper limiting portion 51 and the lower limiting portion 52, one end of the clamping member 40 is the front end, and the other end is the rear end. The clamping member 40 is provided with the rotation stopping blocking strip 80, and the front end of the clamping member 40 is inserted between the upper limiting portion 51 and the lower limiting portion 52 until the rotation stopping blocking strip 80 abuts against one end of the upper blocking strip and / or the lower blocking strip.

[0066] Wherein, both ends of the upper and lower stop bars are open, in this state, the clamping member 40 (preferably a bar structure as long as the upper and lower stop bars) can enter the locking position from either end. In this embodiment, the ends of the end stop bar 532 are connected to the ends of the upper and lower stop bars that are close to each other, so that the upper and lower stop bars and the end stop bar 532 form a U-shaped structure, and the clamping member 40 enters from the open end, so that the end stop bar 532 prevents the clamping interface 41 and the limiting protrusion 531 from falling off from the other end due to excessive rotation when the clamping member 40 enters the locking position. Preferably, when the front end of the clamping member 40 abuts the inner side of the end stop bar 532, the clamping interface 41 and the limiting protrusion 531 are just engaged.

[0067] In addition, this embodiment also discloses a rotation stop bar 80, which is preferably connected to the rear end of the clamping member 40 and extends downward at the other end, and abuts one end of the lower stop bar when the clamping interface 41 and the limiting protrusion 531 are just engaged. In the above, if the other end of the rotation stop bar 80 extends upward, the rotation stop bar 80 abuts one end of the upper stop bar; further, the rotation stop bar 80 is connected to one end of the clamping member 40, that is, the rotation stop bar 80 and the clamping member 40 form a T-shaped structure, and the rotation stop bar 80 abuts one end of the upper and lower stop bars.

[0068] In addition, the end stop bar 532 and the rotation stop bar 80 can be used alone or in combination, which is not limited here.

[0069] Optionally, the limiting member 50 is arranged on the inner wall of the bottle mouth assembly 20, and the clamping member 40 is arranged on the outer wall of the bottle body 10; or, the limiting member 50 is arranged on the inner wall of the bottle mouth assembly 20, and the clamping member 40 is arranged on the outer wall of the bottle body 10; a window 210 is arranged on the side wall of the bottle mouth assembly 20, which communicates the inside and outside of the bottle mouth assembly 20 and is located between the upper and lower stop bars.

[0070] Wherein, the mouth end of the bottle body 10 is sleeved in the connecting end, and the limiting member 50 is arranged on the bottle mouth assembly 20 and the clamping member 40 is arranged on the bottle body 10 as described above. The window 210 can be used to observe the clamping member 40 clamped between the upper and lower stop bars, and to speed up the installation efficiency. Exemplarily, the size of the window 210 matches the locking position. In addition, the clamping member 40 is a protrusion.

[0071] Optionally, the number of limiting members 50 is at least two groups, and the number of clamping members 40 corresponds to the number of limiting members 50.

[0072] For example, taking two sets of limiting members 50 as an example, the two limiting members 50 are symmetrically arranged about the axis of the vacuum bottle. Alternatively, when there are more than two sets of limiting members 50, the multiple sets of limiting members 50 are evenly spaced along the circumference. Multiple limiting members 50 provide multiple connection points for the bottle body 10, making the connection of the bottle body more stable.

[0073] In addition, to improve the sealing of the connection between the bottle mouth assembly 20 and the bottle body 10, a sealing ring is provided at the bottle mouth end.

[0074] Optional, combined Figure 5 The outer wall of the bottle body 10 is provided with anti-slip texture 11.

[0075] The anti-slip texture 11 can be set around the circumference of the bottle body 10, or it can be multiple short raised strips.

[0076] More preferably, the anti-slip texture 11 is a twisted texture, extending along the axial direction of the bottle body 10. The two ends of the twist extend towards the connecting segments of the bottle body 10, presenting a tendency to extend along the axial direction of the bottle body 10. Multiple twists are evenly distributed on the outer wall of the bottle body 10. More specifically, the plane formed after unfolding the bottle body 10 is the projection plane. On the projection plane, the minimum horizontal (X-axis) distance L1 between the midpoints of the two ends of a twist is 5mm-10mm, preferably 7mm, with other dimensions chosen as needed. The minimum horizontal (X-axis) distance L2 between the midpoints of the same end of two adjacent twists is 1.5mm-2.5mm, preferably 2.0mm, with other dimensions chosen as needed. Alternatively, L1 = 3*L2~4*L2, and the horizontal width of the twist itself is 1mm-2mm.

[0077] It should be noted that if the horizontal distance L1 between the two ends of a twist is too large, or the horizontal distance L2 between the same end of two adjacent twists is too large, it will be difficult for the hand to grip and apply force.

[0078] Optionally, the bottle nozzle assembly 20 includes an outer support body 21, a liquid outlet head 22, and a pump body 23. A circumferentially arranged through groove 2112 is provided on the side wall of the outer support body 21, with the two ends of the through groove 2112 being the liquid outlet position and the locking position position, respectively. A shielding wall 21120 is provided on the outer side of the locking position position. The liquid outlet head 22 includes a body 221 and an outlet 222 disposed on the side of the body 221. The body 221 is rotatably disposed in the outer support body 21. One end of the outlet 222 is the liquid outlet, which extends into the through groove 2112. The bottle body 10 is connected to the body 221 through the pump body 23, and one end of the bottle body 10 extends beyond one end of the outer support body 21. Rotating the body 221 switches the liquid outlet position between the liquid outlet position and the locking position.

[0079] In the embodiment, the liquid outlet head 22 is rotatably arranged in the outer support body 21. In addition, the liquid outlet is arranged at the liquid outlet position on the through slot 2112 and the clamping position. When needed, the liquid outlet can be rotated to the liquid outlet position. After use, the liquid outlet is rotated to the clamping position. At this time, the liquid outlet is shielded by the shielding wall 21120, thereby avoiding pollution of the liquid outlet.

[0080] For example, in combination with Figure 6 , Figure 7 and Figure 8 , the rotation connection mode of the liquid outlet head 22 and the outer support body 21 is as follows: the outer support body 21 comprises an upper support sleeve 211 and a lower support sleeve 212 arranged in an upper-lower connection mode. The upper support sleeve 211 is internally provided with a clamping protrusion 2111. The clamping protrusion 2111 and the top of the lower support sleeve 212 form a limiting position. The liquid outlet head 22 is externally provided with a flared protrusion 220. The flared protrusion 220 is arranged between the limiting positions. The through slot 2112 is arranged on the sidewall of the upper support sleeve 211 and above the clamping protrusion 2111.

[0081] Optionally, in combination with Figure 9 , Figure 10 and Figure 11 , the pump body 23 comprises a sealing member 231 and a pump core 232. One end of the pump core 232 is connected to the body 221, and the other end is connected to the sealing member 231. The pump core 232 communicates the liquid outlet head 22 and the bottle body 10. The sealing member 231 is sleeved in the outer support body 21. The bottle body 10 is connected with the sealing member 231. The inner wall of the outer support body 21 is provided with a circumferential groove 2121 and an axial groove 2122 which are in communication with each other. The sidewall of the sealing member 231 is provided with a locking protrusion 2311. The locking protrusion 2311 is movably arranged in the circumferential groove 2121 and the axial groove 2122. When the liquid outlet is located at the clamping position, the locking protrusion 2311 is located in the circumferential groove 2121. The circumferential groove 2121 limits the movement of the bottle body 10 towards the pump core 232 in the axial direction of the outer support body 21. When the liquid outlet is rotated from the clamping position to the liquid outlet position, the locking protrusion 2311 located in the circumferential groove 2121 enters the axial groove 2122. The bottle body 10 can move towards the pump core 232 in the axial direction of the outer support body 21.

[0082] The circumferential groove 2121 is arranged at the lower edge of the lower support sleeve 212 and extends along the axial direction of the lower support sleeve 212. The lower part of the circumferential groove 2121 is of an open structure to facilitate the assembly of the locking protrusion 2311. The axial groove 2122 is connected to one end of the circumferential groove 2121 and extends upward. The circumferential groove 2121 and the axial groove 2122 form an L-shaped structure to be arranged on the inner wall of the lower support sleeve 212.

[0083] In the embodiment, when the liquid outlet is in the clamping position, the lock protrusion 2311 is located in the circumferential groove 2121, and the top of the circumferential groove 2121 blocks the upward movement of the lock protrusion 2311 in the axial direction of the vacuum bottle, so that the bottle body 10 cannot press the pump core 232 upward at this time, and the one end of the outlet nozzle 222 is limited in the through groove 2112, and the bottle body 10 and the body 221 cannot press the pump core 232 to pump the liquid. When the liquid outlet is turned to the liquid outlet position, the lock protrusion 2311 is located in the axial groove 2122, and the bottle body 10 can be pushed upward to press the pump core 232 to pump the liquid at this time. Therefore, the circumferential groove 2121 and the axial groove 2122 are used to lock and unlock the movement of the bottle body 10 to the pump core 232, to prevent the liquid from being pumped due to misoperation.

[0084] In addition, one circumferential groove 2121 and one axial groove 2122 form a group, and two groups of circumferential grooves 2121 and axial grooves 2122 are preferably arranged symmetrically on the inner wall of the lower support sleeve 212. Correspondingly, the number of lock protrusions 2311 is also two. In addition, in order to better confirm whether the lock protrusion 2311 enters the circumferential groove 2121 and the axial groove 2122 and is completely in place during operation, vertical ribs are arranged in the circumferential groove 2121 and the axial groove 2122 along the axial direction of the vacuum bottle. The lock protrusion 2311 is provided with a vertical groove matched with the vertical rib, and the lock protrusion 2311 and the corresponding vertical rib can be used to confirm whether the lock protrusion 2311 is in place in the circumferential groove 2121 and the axial groove 2122.

[0085] Furthermore, the above-mentioned rotation of the body 221 changes the position of the liquid outlet. In the above-mentioned embodiment, the body 221 is arranged in the outer support 21, and the top of the body 221 can directly protrude from the top of the upper support sleeve 211 in order to facilitate the rotation of the body 221. In the embodiment, in order to prevent dust and the like from entering the upper support sleeve 211, the body 221 is arranged in the upper support sleeve 211, and a cover 25 is arranged on the bottle nozzle assembly. The cover 25 is connected to the top of the body 221 and partially protrudes from the top of the upper support sleeve 211. The cover 25 is matched with the inner edge of the top of the upper support sleeve 211, thereby covering the top of the upper support sleeve 211. In addition, the top edge of the part of the cover 25 protruding from the top of the upper support sleeve 211 is provided with an inclined surface, and a plurality of force applying concave surfaces 251 are arranged on the inclined surface.
