Description

Technical Field

[0001] The present invention relates to the field of daily necessities, and particularly to a rotatable and telescopic pressing discharging structure, a container, and a nozzle. Background Art

[0002] With the improvement of people's living standards, more and more attention is paid to health and safety issues. The materials in daily necessities containers are often prone to problems such as being air-dried, oxidized, and polluted. Especially in the field of cosmetics, some cosmetics are easily air-dried, oxidized, and polluted due to contact with the external environment, resulting in blockage, pollution, and oxidation of pump-pressed bottled cosmetics. As a result, the cosmetics cannot be pumped, pollute the outer epidermis of the human body, and lose their functions of beautifying and nourishing the skin. In severe cases, it even causes adverse phenomena such as epidermal irritation, allergy, and lesion to the user. Therefore, those skilled in the art urgently need to develop a safe and hygienic bottle body to ensure the hygiene, safety, smooth pumping, and excellent performance during the use of cosmetics. Summary of the Invention

[0003] To solve the problems of the prior art, the present invention provides a rotatable and telescopic pressing discharging structure, a container, and a nozzle, which ensure the hygiene, safety, smooth pumping, and excellent performance of the material inside the container during use.

[0004] The technical solution provided by the present invention is as follows:

[0005] A rotatable and telescopic pressing discharging structure includes: a nozzle, a pressing member, a rotating member, and a valve seat assembly installed on a bottle body; the nozzle is disposed between the pressing member and the valve seat assembly, and the nozzle, the valve seat assembly, and the bottle body are sequentially communicated; the pressing member is rotatably installed on the valve seat assembly to constrain the nozzle to perform linear motion in the radial direction perpendicular to the height direction of the bottle body; the pressing member is provided with an inlet and outlet passage corresponding to the nozzle; and the pressing member can actuated the valve seat assembly along the height direction of the bottle body to realize the conveyance of the material stored in the bottle body; the nozzle is provided with a straight tooth portion, and the valve seat assembly is provided with a gear portion, and the straight tooth portion is meshed and connected with the gear portion; the rotating member rotates and covers the outside of the pressing member, and the rotating member is provided with an inlet and outlet corresponding to the inlet and outlet passage; the end of the pressing member away from the valve seat assembly is exposed outside the rotating member; the rotating member and the pressing member rotate relative to each other or in the same direction to realize the switching of the nozzle between a hidden state and an exposed state.

[0006] In the above technical solution, the inlet and outlet channels are in a communicating state with the inlet and outlet. By the co-rotating of the rotating member and the pressing member, the pressing member can drive the straight tooth portion to rotate around the gear portion. Due to the restraining effect of the pressing member, the nozzle can be extended and retracted in the inlet and outlet channels and the inlet and outlet. When the nozzle is in the extended state, pressing the pressing member can pump out the material in the bottle body for the user to use; when the nozzle is in the retracted state, the rotating member and the pressing member rotate relatively, so that the inlet and outlet are in a misaligned state with the inlet and outlet channels. At this time, the side wall of the rotating member without the inlet and outlet blocks the nozzle, so that the nozzle is not exposed to the external environment, ensuring that the material filled in the bottle body does not contact the external environment; thus, the nozzle is exposed to the external environment during use. During the use process, since the nozzle extends, the material will not stay on the bottle body. The user can directly catch the pumped material without contacting the nozzle, which is convenient, healthy, safe and avoids waste; when not in use, the nozzle is hidden inside the rotating member and not exposed to the external environment, avoiding the direct contact of the material with the external environment and causing adverse phenomena such as air drying, oxidation, caking, etc., ensuring the fluidity of the material, and thus ensuring the smoothness of the material pumping; due to the shielding of the rotating member, the nozzle does not directly contact the external environment, ensuring the hygiene at the nozzle, improving the hygiene and health of the material use, and further ensuring the functions such as skin beautification and skin care of the material, making the performance of the material excellent, and also avoiding adverse phenomena such as epidermal irritation, allergy, and lesion caused by the user's unhygienic situation.

[0007] Further, a first limiting member protrudes outward in the radial direction on the outer side wall of the pressing member; a second limiting member protrudes inward in the radial direction on the inner side wall of the rotating member; the first limiting member and the second limiting member are circumferentially oppositely arranged; when the rotating member and the pressing member rotate relatively, the first limiting member and the second limiting member approach each other, and the inlet and outlet channels and the inlet and outlet switch between the misaligned state and the communicating state; when the rotating member and the pressing member rotate in the same direction, the first limiting member and the second limiting member abut against each other, the inlet and outlet channels and the inlet and outlet are in a communicating state, the rotating member drives the pressing member to rotate, so that the straight tooth portion rolls on the gear portion, and the nozzle makes a linear motion and extends or retracts at the inlet and outlet.

[0008] In the above technical solution, through the circumferentially arranged and oppositely arranged limiting members (the first limiting member, the second limiting member), the relative rotation and co-rotation of the pressing member and the rotating member can be realized. The structure is simple, reliable and easy to implement. More preferably, since the limiting members are all arranged inside the rotating member, the appearance aesthetic feeling and the overall sense of the bottle body are ensured, and the artistic sense of the bottle body is improved.

[0009] Further, one limiting member one is correspondingly provided with two limiting members two; the two limiting members two include a first limiting member two and a second limiting member two; the first limiting member two and the second limiting member two are circumferentially spaced apart, and the limiting member one can freely rotate in the spaced space between the first limiting member two and the second limiting member two; when the inlet / outlet is in a misaligned state with the inlet / outlet passage, the limiting member one abuts against the first limiting member two; when the inlet / outlet is in a communicating state with the inlet / outlet passage, the limiting member one abuts against the second limiting member two.

[0010] Further, one limiting member two is correspondingly provided with two limiting members one; the two limiting members one include a first limiting member one and a second limiting member one; the first limiting member one and the second limiting member one are circumferentially spaced apart, and the limiting member two can freely rotate in the spaced space between the first limiting member one and the second limiting member one; when the inlet / outlet is in a misaligned state with the inlet / outlet passage, the limiting member two abuts against the first limiting member one; when the inlet / outlet is in a communicating state with the inlet / outlet passage, the limiting member two abuts against the second limiting member one.

[0011] In the above technical solution, the setting of the limiting members (limiting member one and limiting member two) realizes the same-direction rotation or relative rotation of the rotating member and the pressing member at the same time, simplifies the structure of the bottle body, enables a wider range of volume changes of the bottle body, is applicable to materials with different capacities, and improves the application range of the bottle body.

[0013] In the above technical solution, the valve seat is used to install and limit the valve member, ensuring the fastening and firmness of the valve member installation and the smoothness of the pressing action.

[0014] Further, the pressing member is provided with a third limiting member; the valve seat is provided with a fourth limiting member; the third limiting member and the fourth limiting member are circumferentially arranged opposite to each other; two fourth limiting members are correspondingly provided for one third limiting member, and the two fourth limiting members include a first fourth limiting member and a second fourth limiting member; the first fourth limiting member and the second fourth limiting member are circumferentially spaced apart, and the third limiting member can freely rotate in the spaced space between the first fourth limiting member and the second fourth limiting member; when the inlet and outlet are in a misaligned state with the inlet and outlet passage, the first fourth limiting member abuts against the third limiting member to limit the further rotation of the pressing member; when the nozzle is in an exposed state, the second fourth limiting member abuts against the third limiting member to limit the further rotation of the pressing member.

[0015] In the above technical solution, the limit positions of the user rotating the rotating member (pressing member) are defined by the circumferentially arranged limiting members (the third limiting member and the fourth limiting member), so as to realize the switching of the nozzle between the hidden state and the exposed state at a relatively small rotation angle (less than 180°), saving the user's time, and prompting the user that the action is in place for the pumping of the material or the nozzle has been hidden in place, improving the convenience and humanization of the use of this bottle body.

[0016] Further, the pressing member is provided with a fifth limiting member; the valve seat is provided with a sixth limiting member; when the nozzle is in a hidden state, the fifth limiting member and the sixth limiting member are arranged opposite to each other in the height direction to limit the movement of the pressing member towards the valve member side; when the nozzle is in an exposed state, the fifth limiting member and the sixth limiting member are misaligned in the height direction, and the pressing member can actuated the valve member in the height direction to realize the conveying of the material.

[0017] In the above technical solution, the limiting members arranged in the height direction (the fifth limiting member and the sixth limiting member) prevent the nozzle in the hidden state from discharging the material due to accidental pressing, thus wasting the material and polluting the bottle body, and improving the safety, convenience and portability of the use of this bottle body.

[0020] Further, a first flap protrudes inward in the radial direction on the inner side wall of the rotating member; a first lever is provided on the valve seat corresponding to the first flap; when the inlet / outlet and the inlet / outlet passage are switched between the misaligned state and the communicating state, the first flap and the first lever move circumferentially towards each other and pass by each other; a second flap protrudes inward in the radial direction on the inner side wall of the rotating member; a second lever is provided on the valve seat corresponding to the second flap; when the nozzle is switched between the hidden state and the exposed state, the second flap and the second lever move circumferentially towards each other and pass by each other.

[0021] In the above technical solution, the touch feeling (jamming feeling) and / or the sound generated when the flap and the lever pass by each other remind the user that the action is in place. For example, whether the inlet / outlet passage and the inlet / outlet are in the hidden state or the communicating state, the user can directly identify it by sound; whether the nozzle is in the extended state or the retracted state, the user can directly identify it through the five senses; this greatly improves the convenience of using this bottle body; more preferably, the correspondingly arranged flap and lever also have a certain limiting effect, preventing the nozzle of this bottle body from being exposed to the external environment due to friction with other items during the carrying process, and improving the hygiene, safety and health of using this bottle body.

[0022] Further, the valve seat is provided with a first annular wall, and the first annular wall is provided with a first valve member passage for inserting the valve member; the outer side wall of the valve member is sealingly connected to the inner side wall of the first valve member passage.

[0062] In the following description, specific details such as specific system architectures, technologies, etc. are presented for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0063] It should be understood that when used in this specification and the appended claims, the term "comprising" indicates the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups.

[0064] To simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product. Additionally, to simplify the drawings for easy understanding, for components with the same structure or function in some figures, only one of them is schematically illustrated, or only one of them is labeled. In this document, "one" not only means "only this one" but also can mean "more than one" situation. In this document, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In this document, for the sake of convenience of description, the depth direction of the bottle body (i.e., the depth direction of the accommodation space) is defined as the height direction, and the direction along the height direction is called the up-down direction; the direction perpendicular to the height direction is defined as the radial direction (when the bottle body has a left-right symmetric structure, the radial direction does not necessarily intersect the symmetry axis), and the direction perpendicular to both the height direction and the radial direction is defined as the left-right direction, but it does not fully represent the actual situation. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0065] In one embodiment of the present invention, as Figure 1-17As shown in the figure, a rotatable, telescopic and pressing discharging structure includes: a nozzle 13, a pressing member 12, a rotating member 11 and a valve seat assembly installed on a bottle body 17; the nozzle 13 is arranged between the pressing member 12 and the valve seat assembly, and the nozzle 13, the valve seat assembly and the bottle body 17 are communicated in sequence; the pressing member 12 is rotatably installed on the valve seat assembly to restrict the nozzle 13 to perform linear motion along the radial direction perpendicular to the height direction of the bottle body 17; the pressing member 12 is provided with an inlet and outlet channel 1220 corresponding to the nozzle 13; and the pressing member 12 can actuate the valve seat assembly along the height direction of the bottle body 17 to realize the conveying of the material stored in the bottle body 17; the nozzle 13 is provided with a straight tooth portion 1321, and the valve seat assembly is provided with a gear portion 1421, and the straight tooth portion 1321 is meshed and connected with the gear portion 1421; the rotating member 11 rotates and covers the outside of the pressing member 12, and the rotating member 11 is provided with an inlet and outlet 1111 corresponding to the inlet and outlet channel 1220; the end of the pressing member 12 on the side away from the valve seat assembly is exposed outside the rotating member 11; the rotating member 11 and the pressing member 12 rotate relatively or in the same direction to realize the switching of the nozzle 13 between the hidden state and the exposed state.

[0066] Specifically, when not in use by the user, the inlet / outlet 1111 and the access channel 1220 are in a misaligned state at this time. The side wall of the rotating member 11 blocks the access channel 1220, thereby achieving the blocking of the nozzle 13 retracted into the access channel 1220, so that the nozzle 13 is in a hidden state, avoiding adverse phenomena such as contamination, air drying, and oxidation of the nozzle 13 due to exposure to the external environment; when the user uses it, the user rotates the rotating member 11, so that the rotating member 11 and the pressing member 12 rotate relative to each other, making the inlet / outlet 1111 communicate with the access channel 1220. At this time, the retracted nozzle 13 can be seen through the inlet / outlet 1111. Continuing to rotate the rotating member 11 (or the pressing member 12) in the same direction, so that the rotating member 11 and the pressing member 12 rotate in the same direction. Due to the constraint of the pressing member 12 on the nozzle 13, while the pressing member 12 drives the nozzle 13 to rotate, the straight tooth portion 1321 rolls around the gear portion 1421, making the nozzle 13 perform a linear motion in the radial direction, thereby realizing the extension of the nozzle 13 in the access channel 1220 and the inlet / outlet 1111. When the nozzle 13 is in the extended state, the user can press the pressing member 12 in the height direction to actuate the valve seat assembly to pump the material in the bottle 17, and the material flows out from the nozzle 13; after the user finishes using it, rotate the rotating member 11 (or the pressing member 12) in the reverse direction, so that the rotating member 11 and the pressing member 12 rotate in the reverse same direction. Due to the constraint of the pressing member 12 on the nozzle 13, while the pressing member 12 drives the nozzle 13 to rotate, the straight tooth portion 1321 rolls around the gear portion 1421, making the nozzle 13 perform a linear motion in the radial direction, thereby realizing the retraction of the nozzle 13 in the inlet / outlet 1111 and hiding it in the access channel 1220.

[0075] Specifically, as Figure 2 、 12As shown in FIGS. 12 and 13, the rotating member 11 includes a cylinder 111 that communicates in the height direction. The cylinder 111 is provided with an inlet / outlet 1111. The lower end of the cylinder 111 in the height direction is rotatably installed on the valve seat assembly. The pressing member 12 is sleeved inside the cylinder 111. On the inner side wall of the upper end of the cylinder 111 in the height direction, two limiting posts extending in the height direction protrude. Among them, the limiting post on the left forms a first second limiting member 11121, and the limiting post on the right forms a second second limiting member 11122. The central angle corresponding to the interval space between the first second limiting member 11121 and the second second limiting member 11122 is set to be not less than twice the central angle corresponding to the access channel 1220, that is, only the exposure and occlusion of the access channel 1220 need to be realized. Preferably, the central angle corresponding to the interval space between the first second limiting member 11121 and the second second limiting member 11122 is 12 - 40°. Preferably, a plurality (not less than two) of seventh limiting members 1113 are sequentially arranged at intervals along the height direction on the inner side wall of the cylinder 111. The central angles of different seventh limiting members 1113 can be the same or different, and at least one seventh limiting member 1113 is located above the pressing member 12 in the height direction at the upper end of the cylinder 111. The seventh limiting member 1113 can be flush with the upper end of the cylinder 111. At least one seventh limiting member 1113 is sleeved on the outer side wall of the upper end of the pressing member 12 to ensure the concentric installation of the pressing member 12 and the rotating member 11. At least one seventh limiting member 1113 abuts against the eighth limiting member 1416 in the height direction.

[0076] Preferably, there are four seventh limiting members 1113 that abut against the eighth limiting member 1416, two of which are on the left, two are on the right, the two on the left are arranged at intervals in the height direction and are located below the first second limiting member 11121, and the two on the right are arranged at intervals in the height direction and are located below the second second limiting member 11122. To facilitate the pressing of the pressing member 12, a pressing notch 1116 is provided at the upper end of the cylinder 111, which is convenient for the user to press the pressing member 12 on the outer peripheral side of the rotating member 11. Of course, the pressing notch 1116 may not be provided, and the user can also press the pressing member 12 above the rotating member 11. On the inner side wall of the upper end of the rotating member 11, a first dial 1114 and a second dial 1115 protrude. The first dial 1114 is arranged on the same side as the first second limiting member 11121, the second dial 1115 is arranged on the same side as the second second limiting member 11122, and the upper ends of the first dial 1114 and the second dial 1115 are integrally provided with the seventh limiting member 1113 at the upper end, but the lower ends of the first dial 1114 and the second dial 1115 are located below the seventh limiting member 1113. The integral setting of the first dial 1114 and the second dial 1115 with the limiting member can improve their mechanical strength and extend their service life. Similarly, the abutment of the plurality of seventh limiting members 1113 and the plurality of eighth limiting members 1416 can improve the connection strength between the rotating member 11 and the valve seat assembly and prevent the rotating member 11 from falling off the valve seat assembly.

[0077] As Figure 3 and 4 shown, the pressing member 12 includes a pressing portion 121 and an annular wall 122 extending from the outer peripheral wall of the pressing portion 121 toward the valve seat 14; the pressing portion 121 is exposed on the rotating member 11; on the side of the pressing portion 121 facing the annular wall 122, a first rib plate 1211 and a second rib plate 1212 are oppositely provided and protruded; the first rib plate 1211, the second rib plate 1212, and the pressing portion 121 together enclose a guiding channel 1213 for accommodating the nozzle 13; at a position corresponding to the guiding channel 1213 on the annular wall 122, an inlet and outlet channel 1220 is provided; the inlet and outlet channel 1220 is communicated with the guiding channel 1213. Preferably, a part of the structure of the nozzle 13 is accommodated in the guiding channel 1213, so as to realize the concave-convex fit between the guiding channel 1213 and the nozzle 13, and further realize that when the straight tooth portion 1321 makes a relative rolling around the gear portion 1421, the reciprocating motion of the straight tooth portion 1321 is a linear motion. Preferably, on the side of the pressing portion 121 facing the nozzle 13, a contact rib plate 1214 is protruded, and more than one contact rib plate 1214 contacts the end surface of the nozzle 13 on the side close to the pressing portion 121, so as to realize the limit of the nozzle 13 in the height direction. At the same time, since the guiding channel 1213 has a limit on the nozzle 13 in the left and right directions, the phenomenon that the nozzle 13 moves up and down or left and right is avoided, and the stability and linearity of the movement of the nozzle 13 are ensured.

[0078] On the outer side wall of the annular wall 122, a first limiting block 1223 protrudes. The first limiting block 1223 is located between the first second limiting member 11121 and the second second limiting member 11122. The first limiting block 1223 is a stepped structure, including a first sub-limiting block and a second sub-limiting block. The first sub-limiting block is arranged above the second sub-limiting block in the height direction. The first sub-limiting block and the second sub-limiting block are not flush on the side close to the first second limiting member 11121, and the first sub-limiting block and the second sub-limiting block are flush on the side close to the second second limiting member 11122; The first sub-limiting block forms a first limiting member. The left side wall of the first sub-limiting block on the side close to the first second limiting member 11121 forms a first abutting portion 12231, and the first abutting portion 12231 is circumferentially opposite to the first second limiting member 11121; The right side wall of the first sub-limiting block on the side close to the second second limiting member 11122 forms a fourth abutting portion 12234, and the fourth abutting portion 12234 is circumferentially opposite to the second second limiting member 11122; The second sub-limiting block forms a first limiting member. The left side wall of the second sub-limiting block on the side close to the first second limiting member 11121 forms a second abutting portion 12232, and the second abutting portion 12232 is circumferentially opposite to the first second limiting member 11121; The lower side wall of the second sub-limiting block on the side close to the valve seat 14 forms a third abutting portion 12233, and the third abutting portion 12233 forms a fifth limiting member 1225; Since the first abutting portion 12231 and the second abutting portion 12232 are not flush, but the first abutting portion 12231 and the second abutting portion 12232 are both opposite to the first second limiting member 11121, therefore, the first second limiting member 11121 is also arranged in a stepped shape. Of course, it can also be that the first abutting portion 12231 and the second abutting portion 12232 are respectively circumferentially opposite to a second limiting member. Preferably, the first limiting block 1223 is arranged below the pressing notch 1116.

[0079] On the outer sidewall of the annular wall 122, a plurality of first limiting members extending along the circumferential direction of the annular wall 122 protrude, including a first first limiting member 1221 and a second first limiting member 1222. The first flap 1114 is disposed between a set of correspondingly arranged first first limiting member 1221 and second first limiting member 1222, and the second flap 1115 is disposed between a set of correspondingly arranged first first limiting member 1221 and second first limiting member 1222; at this time, the first flap 1114 and the second flap 1115 respectively form a second limiting member, and the limiting member seven 1113 connected to the first flap 1114 and the second flap 1115 abuts against the upper sides of the first first limiting member 1221 and the second second limiting member 11122 in the height direction to prevent the pressing member 12 from slipping off the upper end of the cylinder 111. Preferably, in order to facilitate the first flap 1114 to cross the first lever 1411 and the second flap 1115 to cross the second lever 1412, the first flap 1114 and the second flap 1115 can be in a sheet structure, or the lower ends of the first flap 1114 and the second flap 1115 and the upper ends of the first lever 1411 and the second lever 1412 are made into tips, or the upper ends of the first lever 1411 and the second lever 1412 are in a sheet structure.

[0080] On the outer sidewall of the annular wall 122, a second limiting block protrudes. The second limiting block is disposed at the access channel 1220, and the access channel 1220 penetrates through the second limiting block. The upper end of the second limiting block is flush with the upper ends of the first first limiting member 1221 and the second first limiting member 1222. The second limiting block forms a third limiting member 1224. To be precise, the left sidewall and the right sidewall of the second limiting block form the third limiting member 1224, and the lower end surface of the second limiting block forms a fifth limiting member 1225. That is, the second limiting block simultaneously functions as the third limiting member 1224 and the fifth limiting member 1225. Preferably, more than one limiting member seven 1113 is circumferentially opposite to the second limiting block. At this time, the second limiting block also functions as a first limiting member, and the limiting member seven 1113 functions as a second limiting member. Preferably, the second limiting block is disposed between two limiting members seven 1113 that are on the same circumference and spaced apart. Both the first limiting block 1223 and the second limiting block have the functions of multiple limiting members, thereby simplifying the structure of the pressing member 12, reducing the processing difficulty of the pressing member 12, and at the same time improving the structural compactness and structural strength of the present bottle cap; similarly, the limiting member seven 1113 also has multiple functions to achieve the circumferential limit between the rotating member 11 and the pressing member 12, and at the same time achieve the height direction limit between the rotating member 11 and the valve seat 14, reducing the processing difficulty of the rotating member 11, and at the same time improving the structural compactness and structural strength of the present bottle cap.

[0081] When the inlet / outlet 1111 and the access channel 1220 are in a misaligned state, the fourth abutting portion 12234 abuts circumferentially against the second limiting member II 11122, and the first flap 1114 abuts against the first limiting member I 1222; the second flap 1115 is clamped between the second lever 1412 and the first limiting member I 1221, that is, after the second flap 1115 passes over the second lever 1412, it abuts circumferentially against the first limiting member I 1221; one or more seventh limiting members 1113 circumferentially opposite to the second limiting block abut circumferentially against the third limiting member 1224 (i.e., the left side wall of the second limiting block).

[0082] When the inlet / outlet 1111 and the access channel 1220 are in a communicating state, the first abutting portion and the second abutting portion respectively abut circumferentially against the second limiting member I 11121, and the first flap 1114 abuts circumferentially against the first limiting member I 1221; the second flap 1115 abuts circumferentially against the first limiting member I 1222 after passing over the second lever 1412; one or more seventh limiting members 1113 circumferentially opposite to the second limiting block abut circumferentially against the third limiting member 1224 (i.e., the right side wall of the second limiting block).

Preferably, a ring groove 13231 is provided at the contact portion between the hard pipe section 1323 and the hose section 131, so that a hook portion is formed between the end portion of the hard pipe section 1323 close to the hose section 131 and the ring groove 13231, so as to improve the fastening property of the connection between the hard pipe section 1323 and the hose section 131. In practical applications, the hard pipe section 1323 and the hose section 131 can be directly formed into a finished product by injection molding; it can be directly installed. Of course, the hose section 131 and the hard pipe section 1323 can also be processed and formed separately, and then the hard pipe section 1323 is inserted into the hose section 131 to achieve their connection. At this time, the hard pipe section 1323 and the hose section 131 are hermetically connected, such as by interference fit or adhesion with an adhesive. Preferably, a convex block 1311 is provided on the outer side wall of the hose section 131; a limiting groove 13223 is provided on the side wall of the channel 13221; the convex block 1311 is received in the limiting groove 13223. Preferably, the limiting groove 13223 is provided on the side wall of the channel 13221 (i.e., the body 1322) along the height direction of the hard pipe section 1323. The limiting groove 13223 and the convex block 1311 realize the limitation of the hose section 131 in the left and right directions, the height direction, and the radial direction, thereby ensuring the stability of the docking between the hose section 131 and the valve member 15. When the nozzle 13 makes a linear reciprocating motion, the deformation performance of the hose section 131 is utilized to adapt to the characteristics that one end of the hose section 131 is fixed (the lower end connected to the valve member 15 needs to be fixed), and the other end is movable (the upper end connected to the hard pipe section 1323 needs to move linearly with the hard pipe section 1323).

[0084] It should be noted that the hose section 131 can achieve the characteristics of fixing one end and moving the other end by deforming itself or by changing its structural shape while keeping its length unchanged. The specific implementation methods will not be elaborated here. Preferably, the bump 1311 is a stepped structure, so that the bump 1311 forms a lower stepped portion with a first abutting surface 13111 and an upper stepped portion with a second abutting surface 13112. The second abutting surface 13112 radially abuts against the inner side wall of the channel 13221. When the limiting groove 13223 does not penetrate the side wall of the channel 13221, the first abutting surface 13111 radially abuts against the inner side wall of the limiting groove 13223. Of course, when the limiting groove 13223 penetrates the side wall of the channel 13221, the first abutting surface 13111 does not radially abut against the inner side wall of the limiting groove 13223. Preferably, the arc-shaped avoidance groove 13222 is arranged on the side wall of the channel 13221, so that the arc-shaped avoidance groove 13222 communicates with the channel 13221.

At this time, the feeding of the material can be realized by pressing the pressing member 12. And when the third abutting portion 12233 of the first limiting block 1223 abuts against the sixth abutting portion 14175 in the height direction, the continuous downward pressing of the pressing member 12 is restricted. At the same time, the second abutting portion 12232 of the first limiting block 1223 abuts against the fourth first limiting member 14171 in the circumferential direction, so that the rotating member 11 and the pressing member 12 cannot rotate continuously to the right; when the nozzle 13 is in the retracted state, the first limiting block 1223 is located in the second sub-notch. At this time, the sixth limiting member 14173 abuts against the third abutting portion 12233 of the first limiting block 1223 in the height direction to restrict the pressing of the pressing member 12, avoiding the phenomenon of feeding the material due to accidentally pressing the pressing member 12 and avoiding the waste of the material; when the inlet and outlet 1111 and the access channel 1220 are in the misaligned state, the sixth limiting member 14173 abuts against the third abutting portion 12233 of the first limiting block 1223 in the height direction, and the pressing member 12 cannot be pressed down either. At the same time, the fourth second limiting member 14172 abuts against the fourth abutting portion 12234 of the first limiting block 1223 in the circumferential direction, so that the rotating member 11 cannot rotate continuously to the left.

The upper end surface of the upper cylinder wall at the first sub-notch forms a fifth abutting portion 14174. The upper end surface of the upper cylinder wall at the fourth sub-notch forms a sixth limiting member 14173. The right side wall of the upper cylinder wall near the fourth sub-notch forms a fourth first limiting member 14171; when the nozzle 13 is in the extended state, the second limiting block is located in the third sub-notch.

At the same time, the third limiting member 1224 of the second limiting block abuts against the fourth second limiting member 14172 circumferentially, so that the rotating member 11 and the pressing member 12 cannot rotate continuously to the left; when the nozzle 13 is in the retracted state, the second limiting block is located in the fourth sub-notch. At this time, the sixth limiting member 14173 abuts against the fifth limiting member 1225 in the height direction to limit the pressing of the pressing member 12, avoiding the phenomenon of material conveying caused by accidentally pressing the pressing member 12 and avoiding the waste of the material; when the inlet / outlet 1111 and the inlet / outlet channel 1220 are in the misaligned state, the sixth limiting member 14173 abuts against the fifth limiting member 1225 in the height direction, and the pressing member 12 cannot be pressed down either. At the same time, the third limiting member 1224 abuts against the fourth first limiting member 14171 circumferentially, so that the rotating member 11 cannot rotate continuously to the right.

[0087] On the outer wall of the upper cylinder wall where notch one 1414 and notch two 1415 are not provided, a limiting member eight 1416 protrudes radially outward. On the outer wall of the upper cylinder wall where notch one 1414 and notch two 1415 are provided, a limiting member eight 1416 protrudes radially outward, so that two groups of limiting members seven 1113 and limiting member eight 1416 that are in contact with each other along the height direction are provided on the upper cylinder wall and the rotating member 11 along the height direction. The long slot 1413 can penetrate the upper end of the upper cylinder wall along the height direction, but the long slot 1413 does not penetrate the lower end of the upper cylinder wall. Preferably, both the first lever 1411 and the second lever 1412 protrude from the upper end surface of the upper cylinder wall, and a first limiting member four 14171 is formed on the right side wall of the first lever 1411, and a second limiting member four 14172 is formed on the left side wall of the second lever 1412.

The gear portion 1421 is provided on the right side of the first valve member passage 1422 and is arranged around the first valve member passage 1422. Preferably, the gear portion 1421 is provided on the upper end surface of the first annular wall 142. The central angle of the gear portion 1421 can be set according to the length dimension of the hard pipe section 1323. Preferably, the central angle of the gear portion 1421 is 45 - 70°. As can be seen from the above, the present invention realizes the switching between the hidden state and the exposed state of the nozzle 13 without rotating the rotating member 11 to 180°, reducing the rotation angle of the user and improving the user's use efficiency. Preferably, the relative rotation angle between the rotating member 11 and the pressing member 12 is 18°, and the same-direction rotation angle between the rotating member 11 and the pressing member 12 is 52°. Preferably, the pressure seat 16, the valve seat 14, the valve member 15, the pressing member 12, the rotating member 11, and the gear portion 1421 are all concentrically arranged. Preferably, the outer wall of the pressure seat 16 is hermetically connected and fixed to the bottle body 17, so that the user can rotate the rotating member 11 with one hand and hold the bottle body 17 with the other hand to realize the switching between the hidden state and the exposed state of the nozzle 13. The user can also rotate the bottle body 17 with one hand and hold the rotating member 11 with the other hand to realize the switching between the hidden state and the exposed state of the nozzle 13. At this time, the rotating member 11 can be sleeved on the outside of the valve seat assembly.

The upper section valve body is arranged close to the pressing member 12. A limiting boss 151 is arranged at the end of the lower section valve body close to the upper section valve body.

[0089] It should be noted that in this embodiment, the rotation member 11 is rotated rightward (i.e., counterclockwise) to make the inlet / outlet 1111 communicate with the inlet / outlet passage 1220, and the rotation member 11 is continuously rotated rightward to make the rigid pipe section 1323 extend out of the inlet / outlet 1111 (during this process, since the first limiting member and the second limiting member are circumferentially abutted, the rotation member 11 and the pressing member 12 can rotate in the same direction); when the rigid pipe section 1323 is in the extended state, the rotation member 11 is rotated leftward (i.e., clockwise) to make the rigid pipe section 1323 retract into the inlet / outlet passage 1220 (during this process, since the rigid pipe section 1323 penetrates through the inlet / outlet 1111, the rotation member 11 and the pressing member 12 can rotate in the same direction), and when the nozzle rigid pipe section 1323 is in the retracted state, at this time the rigid pipe section 1323 is separated from the inlet / outlet 1111, and the rotation member 11 is continuously rotated leftward to make the inlet / outlet 111 and the inlet / outlet passage 1220 be arranged in a dislocation manner (during this process, since the third limiting member and the fourth limiting member are circumferentially abutted, the pressing member 12 no longer rotates in the same direction as the rotation member 11, and at this time, the rotation member 11 and the pressing member 12 rotate relatively). Of course, by swapping the positions of each component left and right, it is also possible to rotate the rotation member 11 rightward (i.e., counterclockwise) to make the rigid pipe section 1213 extend and the inlet / outlet 1111 and the inlet / outlet passage 1220 be in a dislocation state, and rotate the rotation member 11 leftward (i.e., clockwise) to make the rigid pipe section 1213 retract and the inlet / outlet 1111 and the inlet / outlet passage 1220 communicate with each other.

[0090] In another embodiment of the present invention, different from the above embodiment, the rotation member 11 is only sleeved on the upper end of the pressing member 12 and the valve seat assembly, while the lower end of the valve seat assembly is exposed to the external environment. At this time, the valve seat assembly can be fixedly connected to the bottle body 17 or rotatably installed on the bottle body 17. Then, when realizing the switching between the hidden state and the exposed state of the nozzle 13, the user rotates the rotation member 11 with one hand and holds the valve seat assembly with the other hand, or the user can also rotate the valve seat assembly with one hand and hold the rotation member 11 with the other hand.

The supporting boss 1621 is arranged around the second valve member channel 1622, and the second valve member channel 1622 penetrates through the supporting boss 1621. Therefore, the limiting boss 151 is clamped between the supporting boss 1621 and the first annular wall 142.

A limiting strip protrudes radially outward from the outer side wall of the inner liner 172 near the opening 175. The outer bottle body 171 is provided with a mounting groove corresponding to the limiting strip.

The lower end surface of the rotating member 11 abuts against the upper end surface of the inner liner 172 in the height direction, thus ensuring the integrity of the entire pressing, rotating, telescopic vacuum bottle of the present invention, without pores on the appearance, and improving the artistic beauty of the pressing, rotating, telescopic vacuum bottle. In practical applications, the cross-section of the bottle body 17 can be circular, regular polygon or irregular polygon, and the cross-sectional shape of the opening 175 can also be circular, regular polygon or irregular polygon, as long as the rotating member 11, the pressing member 12, the valve member 15 and the gear portion 1421 are coaxially arranged.

[0102] In another embodiment of the present invention, different from the above embodiment, the end of the inner liner near the opening 175 is connected to the valve seat assembly. The upper end surface of the outer bottle body 171 is arranged lower than the upper end surface of the inner liner. The lower end surface of the rotating member 11 abuts against the outer bottle body 171 in the height direction. The outer bottle body 171 communicates with the hollow channel 174 through a hole provided on the side wall of the outer bottle body 171. In practical applications, the hole is provided on the peripheral wall or the lower side wall of the outer bottle body 171.

[0103] In another embodiment of the present invention, based on any of the above embodiments, the piston 173 includes an outer cylinder wall 1731, a first inner cylinder wall 1732, a second inner cylinder wall 1733, and a third inner cylinder wall 1734. The cross-sectional dimension of the outer cylinder wall 1731 is larger than the cross-sectional dimensions of the first inner cylinder wall 1732, the second inner cylinder wall 1733, and the third inner cylinder wall 1734. The outer cylinder wall 1731 is sleeved on the outer sides of the first inner cylinder wall 1732, the second inner cylinder wall 1733, and the third inner cylinder wall 1734. The cross-sectional dimension of the first inner cylinder wall 1732 is larger than the cross-sectional dimension of the second inner cylinder wall 1733.

The first annular space 1738 is located above the second annular space 1739. The annular space communicates with the inner space of the inner container 172, and the second annular space 1739 communicates with the hollow channel 174. The outer cylinder wall 1731 is hermetically connected to the inner container 172, and the piston 173 can move upward along the height direction on the inner side wall of the inner container 172 under the pressure difference (the pressure difference between the accommodation space 19 and the external environment). Preferably, the outer cylinder wall 1731 is a quasi-I-shaped member, so that the upper side wall of the first annular space 1738 forms a first sealing member, and the lower side wall of the second annular space 1739 forms a second sealing member.

In practical applications, the hard pipe section 1323 and the hose section 131 can be directly formed into a finished product by injection molding; it can be directly installed. Of course, the hose section 131 and the hard pipe section 1323 can also be processed and formed separately, and then the hard pipe section 1323 is inserted into the hose section 131 to achieve their connection. At this time, the hard pipe section 1323 and the hose section 131 are hermetically connected, such as by interference fit or adhesion with an adhesive.

When the nozzle 13 makes a linear reciprocating motion, the deformation performance of the hose section 131 is utilized to adapt to the characteristics that one end of the hose section 131 is fixed (the lower end connected to the valve member 15 needs to be fixed), and the other end is movable (the upper end connected to the hard pipe section 1323 needs to move linearly with the hard pipe section 1323).

[0105] It should be noted that the hose section 131 can achieve the characteristic that one end is fixed and the other end is movable by deforming itself or by changing its structural shape while keeping its length unchanged.

When the limiting groove 13223 does not penetrate the side wall of the channel 13221, the first abutting surface 13111 radially abuts against the inner side wall of the limiting groove 13223. Of course, when the limiting groove 13223 penetrates the side wall of the channel 13221, the first abutting surface 13111 does not radially abut against the inner side wall of the limiting groove 13223. Preferably, the arc-shaped avoidance groove 13222 is arranged on the side wall of the channel 13221, so that the arc-shaped avoidance groove 13222 communicates with the channel 13221.
