DETAILED DESCRIPTION

[0026] The drawings in the present disclosure are not strictly drawn to scale, and the number of water inlet pipes 111, the number of air inlet pipes 113, and the number of air inlet one-way valves 3 are not limited to the number shown in the drawings. The specific size and number of each structure can be determined according to actual needs. The drawings described in the present disclosure are only structural schematic diagrams.

[0027] Referring to Figure 1 , the bottle cap assembly provided by at least one embodiment of the present application cooperates with a portable water dispenser. The bottle cap assembly includes a cap body 1 formed by one-piece injection molding. The cap body 1 includes a cap top 11 cooperating with the portable water dispenser, and a cap body 12 cooperating with a bottle body. The cap body 12 is provided with threads at a position thereof, so as to cooperate with the threads of the bottle mouth of a commercially available bottled water bottle body.

[0028] In some embodiments, as shown in Figures 2-4 , the cap body 12 has an installation cavity 121 with an open end. The cap top 11 is formed with a water inlet pipe 111 along an axial direction. The water inlet pipe 111 is formed with a water inlet passage 112 communicating with the installation cavity 121 at a side close to the installation cavity 121. The water inlet passage 112 is slidingly provided with a water inlet valve core 2. The water inlet valve core 2 is sleeved with a first sealing ring 21 at a side of the installation cavity 121. Therefore, the water inlet valve core 2 can block the water inlet passage 112 when the bottle body is inverted.

[0029] As shown in Figure 4 and Figure 5In some embodiments, the water inlet valve core 2 is located at one end of the water inlet pipe 111 and forms a water inlet plug 201 that slides with the wall of the water inlet pipe 111. Multiple water inlet holes 202 are formed along the axial direction at the water inlet plug 201. Multiple water inlet grooves 203 communicating with the water inlet holes 202 are formed on the side wall of the water inlet valve core 2. When the bottle cap assembly is installed on the portable water dispenser, the portable water dispenser has a connecting pipe. The connecting pipe can push the water inlet valve core 2 to move linearly, thereby separating the first sealing ring 21 from the cap body 1. At this time, the water in the bottle can flow through the water inlet groove 203 and the water inlet hole 202 in sequence and enter the connecting pipe, thereby being transported into the portable water dispenser.

[0030] Furthermore, in some embodiments, the diameter of the water inlet hole 202 is smaller than the inner wall diameter of the water inlet pipe 111, the water inlet channel 112 forms a first mating surface 1121 on the side near the water inlet pipe 111, and the water inlet valve core 2 is fitted with a first spring 22 on the side of the water inlet pipe 111. One end of the first spring 22 abuts against the water inlet plug 201, and the other end abuts against the first mating surface 1121.

[0031] Specifically, the first spring 22 can maintain the tendency of the first sealing ring 21 to block the water inlet channel 112, thereby blocking the water inlet channel 112 when the bottle is upright. This can prevent the water in the bottle from contacting the outside world and prevent the water in the bottle from deteriorating. Therefore, the user does not need to use up all the water in the bottle at once. When the water is not needed, the user can simply separate the bottle from the portable water dispenser. At this time, under the action of the first spring 22, the first sealing ring 21 can immediately block the water inlet channel 112.

[0032] The inlet valve core 2 has a first mounting groove 204 on its side wall. The first mounting groove 204 is used to cooperate with the first sealing ring 21, thereby restricting the axial degree of freedom of the first sealing ring 21.

[0033] In some embodiments, see Figure 5 The end of the water inlet valve core 2 located on one side of the mounting cavity 121 forms a first conical surface 205. The first conical surface 205 can reduce the resistance of water to the water inlet valve core 2 when water flows out of the bottle to the portable water dispenser, thereby avoiding the water in the bottle from being difficult to flow out due to high water pressure.

[0034] Seen in Figure 1 In some embodiments, in order to solve the problem of pressure difference between the inside and outside of the bottle, an air inlet pipe 113 is also provided at the top of the cap 11. An air inlet one-way valve 3 is provided in the air inlet pipe 113. The air inlet one-way valve 3 is used to restrict the one-way flow of air from the outside to the mounting cavity 121. Therefore, when water flows out of the bottle into the portable water dispenser, the pressure inside the bottle decreases. By setting the one-way air inlet one-way valve 3, external air can enter the bottle, thereby balancing the pressure difference between the inside and outside of the bottle, and thus avoiding the bottle being flattened by atmospheric pressure, which would cause difficulty in dispensing water.

[0035] Specifically, see Figure 6 , the air inlet pipe 113 is formed with an air inlet channel 114 communicated with the mounting cavity 121 near one end of the mounting cavity 121, the air inlet one-way valve 3 comprises a detachable air inlet valve body 31 and an air inlet valve core 32, the air inlet valve body 31 is formed with an open-ended containing cavity 311 near one end of the air inlet channel 114, the containing cavity 311 is provided with an end cover 33 at the open end, a plurality of first air inlet holes 331 are formed at the end cover 33, the containing cavity 311 is contracted to form a limiting channel 312 at the end away from the end cover 33, the air inlet valve body 31 is provided with a second air inlet hole 313 corresponding to the side away from the end cover 33, the end cover 33 is provided with a second spring 34 near the second air inlet hole 313, and the second spring 34 is used to keep the air inlet valve core 32 close to the second air inlet hole 313.

[0036] Therefore, when the water in the bottle body flows out, the pressure in the bottle body decreases, and under the action of the external atmospheric pressure, the air inlet valve core 32 overcomes the elastic force of the second spring 34 and the pressure of the water in the bottle acting on the air inlet valve core 32, so that the second air inlet hole 313 is communicated with the first air inlet hole 331, at this time, the external pressure is greater than the internal pressure, so that the external gas flows into the bottle body through the second air inlet hole 313 and the first air inlet hole 331, and the pressure in the bottle body gradually increases until it is balanced with the external atmospheric pressure, under the action of the elastic force of the second spring 34 and the pressure of the water in the bottle acting on the air inlet valve core 32, the air inlet valve core 32 moves to the second air inlet hole 313, so that the first air inlet hole 331 and the second air inlet hole 313 are in a non-communicating state.

[0037] In some embodiments, see Figure 7 , the air inlet valve core 32 comprises a guide rod 321, and the end cover 33 is correspondingly formed with a guide hole 332 for sliding fit of the guide rod 321, the guide rod 321 is formed with a first limiting plate 322 away from the guide hole 332, and the first limiting plate 322 can block the second air inlet hole 313, so as to realize isolation between the first air inlet hole 331 and the second air inlet hole 313.

[0038] In some embodiments, see Figure 6 and Figure 7 , the limiting channel 312 is sequentially formed with a second taper surface 3121 and a straight cylindrical surface 3122 away from the end cover 33, the guide rod 321 is formed with a second limiting plate 323 spaced apart from the first limiting plate 322, a second mounting groove 324 is formed between the first limiting plate 322 and the second limiting plate 323, and the second mounting groove 324 is provided with a second sealing ring 35, so that the air inlet valve core 32 has better sealing performance by abutting fit of the second sealing ring 35 and the second taper surface 3121.

[0039] In some embodiments, see Figure 6 and Figure 7The first boss 3231 is arranged on the side of the second limiting plate 323 close to the end cover 33, and the second boss 333 is arranged at the end cover 33 in correspondence, and the first boss 3231 and the second boss 333 are matched with the inner side of the second spring 34, so as to facilitate the installation of the second spring 34.

[0040] In some embodiments, the method comprises Figure 6 and Figure 7 The outer wall of the intake valve body 31 is provided with a third installation groove 314, and the third installation groove 314 is provided with a third sealing ring 36, and the third sealing ring 36 is in interference fit with the inner wall of the air inlet pipe 113, so as to realize the installation of the air inlet check valve 3, that is, the fixed fit of the air inlet check valve 3 and the air inlet pipe 113 is realized through the friction force between the third sealing ring 36 and the air inlet pipe 113.

[0041] It is easy to understand that the skilled in the art can combine, split, recombine and the like on the basis of one or more embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.
