[0023] The following will disclose multiple embodiments of the present utility model in the form of diagrams. For the sake of clarity, many practical details will be described together in the following narrative. However, it should be understood that these practical details are not used to limit the present utility model. That is to say, in some embodiments of the present utility model, these practical details are not necessary. In addition, for the purpose of simplifying the diagrams, some well-known and commonly used structures and components will be illustrated in a simple schematic manner in the diagrams.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0025] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes, and do not particularly refer to the order or sequence. Nor are they used to limit the present utility model. They are merely used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0026] To further understand the content, features, and effects of the present utility model, the following embodiments are cited and described in detail in conjunction with the accompanying drawings as follows:

[0027] Such as Figures 1 to 7As shown in the figure, a liquid bottle cap of the present utility model includes a cap body 1, a top cap 2 and a nozzle 3. The nozzle 3 is detachably installed on the cap body 1. The nozzle 3 is made of silica gel material. The top cap 2 is pivotally connected to the cap body 1. A concave cavity 11 is provided on one side of the cap body 1. An elastic member 4 and a button 5 slidable relative to the concave cavity 11 are provided in the concave cavity 11. The elastic member 4 is a spring; one end of the elastic member 4 elastically presses on the bottom of the concave cavity 11, and the other end elastically presses on the button 5; a first through hole 12 is provided at the bottom of the concave cavity 11. The nozzle 3 is provided with an elastic wall 31 and a laterally extending sealing gasket 32. The elastic wall 31 and the laterally extending sealing gasket 32 are integrally formed on the nozzle 3. A normally closed slit 33 is provided at the connection between the elastic wall 31 and the sealing gasket 32; one end of the button 5 is provided with a pressing portion 51, and the other end is provided with a push rod 52 that can pass through the first through hole 12 and contact the elastic wall 31 of the nozzle 3 and can elastically deform the elastic wall 31 to open the slit 33 to release pressure. Compared with the prior art, the liquid bottle cap of the present utility model has a normally closed slit 33 at the connection between the elastic wall 31 and the sealing gasket 32. When the button 5 is pressed, the push rod 52 overcomes the elastic force of the elastic member 4 to push the elastic wall 31 to elastically deform to open the slit 33 to form an exhaust hole to release the pressure in the bottle. The normally closed slit 33 is directly opposite to the first through hole 12 at the bottom of the concave cavity 11. The high-pressure and high-temperature water vapor enters the first through hole 12 through the opened slit 33 and then enters the concave cavity 11, and then is discharged from the second through hole 15 of the concave cavity 11. The first through hole 12 is horizontally arranged, and the second through hole 15 is vertically arranged. When the top cap 2 is fully opened (as shown in Figure 3 ), dust can only enter the concave cavity 11 from the second through hole 15. The horizontally arranged first through hole 12 effectively prevents the dust entering the concave cavity 11 from entering the slit 33 through the first through hole 12. After the button 5 is released, the button 5 resets under the action of the elastic member 4. The push rod 52 no longer presses the elastic wall 31, and the elastic wall 31 returns to its original state, and the slit 33 closes. When the flip cover 2 is not closed and the liquid bottle is inverted, the liquid in the liquid bottle will not flow out from the slit. Only one set of molds is required to produce the nozzle, and only one process is required when assembling the nozzle to the liquid bottle, which has the advantages of simple structure, high production efficiency and low cost.

[0028] Further, a sliding arm 53 with a first hook 54 is provided on each side of the button 5. Sliding grooves 13 capable of accommodating the sliding arms 53 are provided on both sides of the concave cavity 11. A first locking hole 14 is provided at the bottom of the sliding groove 13. The first hook 54 of the sliding arm 53 is snapped into the first locking hole 14. The snap connection of the hook 54 to the first locking hole 14 can ensure that the button 5 remains in the concave cavity 11 under the action of the elastic member 4 and will not fall off from the concave cavity 11.

[0029] Wherein, a concave portion 34 capable of accommodating the elastic wall 31 when the elastic wall 31 deforms is provided at the rear side of the elastic wall 31. The provision of the concave portion 34 can ensure that the elastic wall 31 can deform under the thrust of the push rod 52.

[0030] Specifically, the gap 33 is inclined, and its inclination angle is 45 degrees. The elastic wall 31 is longitudinally arranged. When the liquid bottle is turned over, the longitudinally arranged elastic wall 31 is subjected to a substantially horizontal pressure from the liquid in the liquid bottle, and the sealing gasket 32 extending horizontally is subjected to a substantially longitudinal pressure from the liquid in the liquid bottle. The pressures of the liquid in the liquid bottle in two directions cause the elastic wall 31 and the sealing gasket 32 to abut against each other, so that the two surfaces of the gap 33 are closely attached to each other and are not easily leaky, effectively preventing the liquid in the liquid bottle from flowing out through the gap 33.

[0031] In addition, a second through hole 15 is provided in the upper part of the cavity 11. The button 5 is provided with a third through hole 55. A first bump 56 and a second bump 57 are respectively provided on both sides of the third through hole 55. The top cover 2 is provided with a connecting arm 21 that can extend into the second through hole 15 and then into the third through hole 55. The connecting arm 21 is provided with a second latching hole 22 latched by the first bump 56 or the second bump 57. When the first bump 56 is latched in the second latching hole 22, the top cover 2 is completely closed on the cover body 1 (as Figure 1 shown), the suction nozzle 3 is bent, and the internal liquid outlet channel is closed due to the bending deformation. When the liquid bottle is turned over, the liquid in the bottle will not flow out; when the second bump 57 is latched in the second latching hole 22, the top cover 2 is opened at a certain small angle under the elastic force of the suction nozzle 3 (as Figure 2 shown), so that the pressure in the liquid bottle is fully released. When releasing, since there is the top cover 2 blocking, the high-pressure and high-temperature water vapor will not directly spray towards people. It effectively realizes the function of preventing the high-pressure and high-temperature water vapor from spraying directly towards people, making it safer to use.

[0032] More specifically, the connection part between the elastic wall 31 and the sealing gasket 32 is an arc part, and the gap 33 is located on the arc part. The arrangement of the gap 33 on the arc part is beneficial to the production and processing of the suction nozzle 3.

[0033] Optionally, a channel 35 is further provided on the sealing gasket 32. Two elastic sheets 36 that are closely attached are provided at the lower end of the channel 35 to seal the lower opening of the channel 35. When sucking the liquid in the liquid bottle, the two closely attached elastic sheets 36 will separate, so that the inside of the liquid bottle is connected to the outside, facilitating the sucking of the liquid in the liquid bottle; when not sucking the liquid, even if the liquid bottle is inverted, the liquid will not flow out through the channel 35.

[0034] In addition, the cover body 1 is provided with a fourth through hole 16, and the suction nozzle 3 is provided with a connecting seat 37 sleeved on the fourth through hole 16 of the cover body 1. During assembly, only the suction nozzle 3 needs to be installed in the fourth through hole 16 of the cover body 1, which has the advantages of simple and convenient installation.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
