[0023] Embodiment 1: As shown in FIG. 1 to FIG. 4, this embodiment provides a bottle with a retractable straw, comprising a bottle body 1, a bottle cap 2 and a straw 3, wherein the bottle cap 2 comprises a bottom cap 21, a rotating sleeve 22 and a top cap 23, the bottom cap 21 covers a mouth of the bottle body 1 and is provided with a first sleeve tube 24, one opening of the first sleeve tube 24 is arranged at the bottom of the bottom cap 21, the other opening of the first sleeve tube 24 extends beyond a top surface of the bottom cap 21, a spiral slideway 25 is arranged on an inner wall of the first sleeve tube 24, the rotating sleeve 22 is arranged on an upper surface of the bottom cap 21, a second sleeve tube 26 is arranged on the rotating sleeve 22, one opening of the second sleeve tube 26 is arranged on an upper surface of the rotating sleeve 22, the other opening of the second sleeve tube 26 extends beyond the bottom of the rotating sleeve 22 and is inserted into the first sleeve tube 24, a vertical sliding groove 27 is formed in a tube wall of the second sleeve tube 26, limiting grooves 28 in opposite directions are formed in upper and lower ends of the sliding groove 27 respectively and connected with the sliding groove 27, a bump 31 is arranged on an outer wall of the straw 3, the straw 3 penetrates into the second sleeve tube 26, the bump 31 penetrates through the sliding groove 27 to be arranged on the spiral slideway 25 of the first sleeve tube 24, and the top cap 23 covers the rotating sleeve 22.

[0024] In this embodiment, the rotating sleeve 22 can be rotated to allow the bump 31 on the straw 3 to slide upwards or downwards along the spiral slideway 25 to realize ascending or descending of the straw 3, such that the straw 3 is retractable. In this way, the straw 3 can stretch out by rotation when used and can retract by reverse rotation when not used. The straw 3 and the bottle body I can be carried as a whole, and the straw 3 can be stored and protected.

[0025] In specific use, the bottle cap 2 is opened directly, then liquid such as water or a drink is poured into the bottle body 1, and next, the bottle cap 2 is closed, that is, the bottom cap 21 covers the bottle body 1. In a default state, the straw 3 is in a retracted state. When a user needs to drink water in the bottle body 1, the top cap 23 of the bottle cap 2 is removed first to uncover the upper opening of the second sleeve tube 26; then, the rotating sleeve 22 is rotated, and in the rotation process of the rotating sleeve 22, the straw 3 is driven to rotate synchronously under the action of the sliding groove 27 and the bump 31; after the straw 3 is rotated, the bump 31 is still located on the spiral slideway 25; if the straw 3 tends to rotate upwards along the spiral slideway 25, the bump 31 is prevented from moving leftward or rightwards by means of the sliding groove 27 and is gradually pushed to slide upwards along the sliding groove 27, the straw 3 is driven to stretch out gradually until the bump 31 enters the limiting groove 28 in the upper end of the sliding groove 27, the straw 3 will not further stretch out anymore after the bump 31 enters the limiting groove 28, and the operation of stretching out the straw 3 is completed. Under the action of the limiting groove 28, the straw 3 will be kept in this state as long as the rotating sleeve 22 is not rotated reversely, that is, the straw 3 will neither further stretch out nor retract, such that customers can use the straw 3 smoothly. When the straw 3 is not used, the rotating sleeve 22 is rotated reversely to allow the bump 31 to disengage from the limiting groove 28 in the upper end of the sliding groove 27, then the bump 31 is prevented to moving leftward or rightwards by means of the sliding groove and slides along the spiral slideway 25 until the bump enters the limiting groove 28, in the opposite direction, in the lower end of the sliding groove 2, at this moment, the straw 3 completely retracts, the top cap 23 is then closed, and the straw 3 is stored.

[0026] Further, to allow the straw 3 to stretch and retract more stably, in this embodiment, two spiral slideways 25 are arranged symmetrically. Similarly, two bumps 31 are arranged symmetrically. In this way, the force during movement can be balanced by means of two symmetrical force application points to allow the straw 3 to move more stably. Moreover, the bumps 31 are cylindrical, such that the bump 31 will not get stuck during the movement process.

[0027] Further, to realize rotary installation of the rotating sleeve 22, in this embodiment, a socket 29 is arranged at the bottom of the rotating sleeve 22, the rotating sleeve 22 is disposed around an upper end of the bottom cap 21 by means of the socket 29 and is able to rotate with respect to the bottom cap 21.

[0028] Further, to allow the top cap 23 to cover the rotating sleeve 22 stably, in this embodiment, an annular projection 101 is arranged on an upper surface of the rotating sleeve 22, and the rotating sleeve 22 is in interference fit with the top cap 23 by means of the annular projection 101.

[0029] Further, to allow customers to know how to rotate the rotating sleeve 22 more easily, in this embodiment, a rotation direction sign 103 for indicating a rotation direction is arranged on an outer wall of the rotating sleeve 22.

[0030] Further, in this embodiment, the bottle body 1 may be made from various materials such as glass, stainless steel, ceramic, silica gel and plastic. In order to improve the anti-skid effect of the bottle body 1, in this embodiment, patterns 102 are arranged on the bottle body 1

[0031] Embodiment 2: As shown in FIG. 5 and FIG. 6, with respect to Embodiment 1, this embodiment adopts another structural design, that is, the positions of the top cap 23, the rotating sleeve 22 and the bottom cap 21 of the bottle cap 2 are changed by arranging structures on the rotating sleeve 22 and the bottom cap 21 at the mouth of the bottle body 1. Specifically, in this embodiment, the bottle with a retractable straw comprises a bottle body 1, a bottle cap 2 and a straw 3, wherein the rotating sleeve 22 is rotatably mounted at a mouth of the bottle body 1, a bottom cap 21 is integrally arranged at the mouth of the bottom body 1, the bottom cap 2 comprises a top cap 23, a first sleeve tube 24 is arranged on the bottom cap 21, one opening of the first sleeve tube 24 is arranged at the bottom of the bottom cap 21, the other opening of the first sleeve tube 24 extends beyond a top surface of the bottom cap 21, a spiral slideway 25 is arranged on an inner wall of the first sleeve tube 24, the rotating sleeve 22 is arranged below the bottom cap 21, a second sleeve tube 26 is arranged on the rotating sleeve 22, one opening of the second sleeve tube 26 is arranged on a lower surface of the rotating sleeve 22, the other opening of the second sleeve tube 26 extends beyond an upper end of the rotating sleeve 22 and is inserted into the first sleeve tube 24, a vertical sliding groove 27 is formed in a tube wall of the second sleeve tube 26, limiting grooves 28 in opposite directions are formed in upper and lower ends of the sliding groove 27 respectively and connected with the sliding groove 27, a bump 31 is arranged on an outer wall of the straw 3, the straw 3 penetrates into the second sleeve tube 26, and the bump 31 penetrates through the sliding groove 27 to be arranged on the spiral slideway 26 of the first sleeve tube 24. In specific use, the principle of the bottle in this embodiment is the same as the principle of the bottle in Embodiment 1, that is, the straw 3 can stretch and retract by means of the sliding groove 27, the bump 31, the limiting grooves 28 and the spiral slideway 25. The operation method of the bottle in this embodiment is the same as the operation method of the bottle in Embodiment 1 and thus will not be repeated anymore here.

[0032] Further, in this embodiment, an opening 104 is formed in an upper end of the bottom cap 21, and users can drink water directly by means of the opening 104.

[0033] Further, to prevent the opening 104 from being exposed when users do not drink water, in this embodiment, a top end of the straw 3 remains exposed when the straw 3 retracts to the bottom, a rotating plate 105 is disposed around an upper end of the straw 3, the size of the rotating plate 105 corresponds to the size of the opening 104, and the rotating plate 105 can be manually shifted to cover the opening 104.

[0034] The above embodiments are merely preferred ones of the invention, and are not intended to limit the patent scope of the invention. All equivalent structures or flow transformations made based on the contents in the specification and drawings of the invention, or direct or indirect applications to other related technical fields should also fall within the patent protection scope of the invention.
