[0003] In order to solve the deficiencies of the prior art, the present application provides a bottled drinking water heating cap, comprising: The bottle cap body has a partition inside, the upper part of the partition is a water storage chamber, and the lower part of the partition is threadedly connected to the bottle mouth; A connecting tube, arranged below the partition and extending into the drinking water bottle, with a gap formed between the connecting tube and the bottle cap body; A heating tube is connected to the bottom end of the connecting tube and is arranged inside the drinking water bottle, and a heating bag is placed inside the heating tube; A sealing member, wherein a water inlet is provided on the interlayer, and the sealing member is arranged at the water inlet for sealing the water inlet; An extrusion piece, one end of which can abut against the sealing piece, and the other end of which passes through the water storage chamber and extends to the outside of the bottle cap body; The top cover is used to seal the portion of the extrusion piece extending out of the bottle cap body.

[0004] Furthermore, the water inlet on the partition is a circular hole, and the sealing member is constructed as a sphere. At least a portion of the upper end of the sphere passes through the partition and enters the water storage chamber. The sealing method of the sphere and the circular hole facilitates opening the water inlet while having a better sealing effect.

[0005] Furthermore, the bottom of the connecting pipe has a through installation groove, a supporting boss is arranged in the installation groove, a spring is arranged on the supporting boss, the top of the spring abuts against the sealing member, and the ball is pressed down by the extrusion member, so that the water in the water storage chamber flows into the heating pipe, and then the extrusion member is released, and the spring is reset, so that the sealing member seals the interlayer to prevent heat from flowing out.

[0006] Furthermore, the extrusion member is an extrusion rod, and the bottom end of the extrusion rod is connected to the sealing member via a connecting member.

[0007] Furthermore, the sealing member is constructed as an aluminum film, and the bottom end of the extruded member includes a puncturing portion and a sealing portion, and the sealing portion is arranged above the puncturing portion and can be threadedly connected to the water inlet.

[0008] Furthermore, a protective cover is arranged on the top end surface of the bottle cap body, the top end of the extrusion piece is not arranged higher than the protective cover, and the top cover is threadedly connected with the protective cover to protect the protruding part of the extrusion rod to prevent the water inlet on the partition from being opened by mistake under normal circumstances.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0022] See also Figure 1-Figure 4 The present embodiment provides a bottled drinking water heating bottle cap, including a bottle cap body 10, wherein the bottle cap body 10 has a layer of interlayer 101 therein to divide the interior thereof into two areas, the upper portion of the interlayer 101 is a water storage chamber 102, the water storage chamber 102 is used to store hot water for reacting with a heating pack, a connecting pipe 11 is provided at the lower portion of the interlayer 101, the connecting pipe 11 and the bottle cap body are an integrally formed structure, and a gap is formed between the connecting pipe 11 and the bottle cap body so that a thread can be provided on the bottle cap body and connected to the bottle mouth, a water inlet 103 connected to the connecting pipe 11 is provided at the middle position of the interlayer, a heating pipe 12 is provided below the connecting pipe 11, the upper portion of the heating pipe 12 is open, the bottom is sealed and a heating pack is placed thereon.

[0023] In the non-heating state, the water inlet 103 needs to be sealed. The water inlet 103 is opened as a circular hole, and a spherical structure is set at the circular hole as a seal. In this embodiment, the seal is a glass ball 13. At least a part of the upper part of the glass ball 13 extends out of the partition and is located in the water storage chamber 102, and the lower part is in the connecting pipe to complete the sealing of the water inlet.

[0024] In order to facilitate the opening and closing of the glass ball 13, a mounting groove 111 is provided at the bottom of the connecting rod 11. The bottom of the mounting groove 111 is a through structure to serve as a water outlet to connect the heating tube 12 below. A supporting boss 112 is circumferentially provided in the mounting groove 111. The supporting boss 112 is provided close to the bottom end of the mounting groove. A spring 14 is provided in the mounting groove 111. The bottom end of the spring 14 abuts against the supporting boss 112, and the top end abuts against the glass ball 13.

[0025] Preferably, the diameter of the spring 14 is sufficient to support the glass ball 13 , and in the initial state, the spring is in a squeezed state to ensure that the glass ball 13 can seal the water inlet 103 .

[0026] A squeezing rod 15 is arranged above the glass ball 13 as a squeezing member, and a connecting member 151 is arranged at the bottom end of the squeezing rod 15. The connecting member 151 can be in contact with or fixedly connected to the glass ball. The purpose of the connecting member 151 is to increase the contact area with the glass ball. Either an arc-shaped cover structure or a hollow columnar structure can be adopted, as long as the glass ball can be stably pressed downward when the squeezing rod 15 is pressed down. Therefore, the bottom end of the squeezing rod 15 should extend out of the upper end of the bottle cap body.

[0027] In addition, a conical structure, such as a truncated cone structure, can be used for sealing at the water inlet, and it can be practical to use a sealing ring. A glass ball can also be used in combination with a sealing ring. This can ensure that under normal circumstances, the water in the water storage chamber will not flow into the heating tube. At the top of the extrusion rod 15, an arc-shaped surface suitable for pressing with fingers can be set, so that the fingers will not be damaged during the downward pressing process.

[0028] An annular protective cover 171 is arranged on the upper end surface of the bottle cap body 10, and the protective cover 171 is used to enclose the part of the extrusion rod 15 extending out of the bottle cap body 10. A top cover 17 is arranged on the outer side of the protective cover 171, and the top cover 17 is threadedly connected to the protective cover 171 to protect the extrusion rod, and the top end of the extrusion rod does not contact the top cover 17.

[0029] After the hot water reacts with the heating bag, a large amount of hot air will rush up, which will cause damage to the connecting tube 11 and the bottle cap body 10. Therefore, a heat-insulating reflux pipe 16 is provided in the heating tube 12. One end of the heat-insulating reflux pipe 16 is an air inlet end 161, which is arranged close to the top of the heating tube 12 and is not aligned with the installation groove position as much as possible. The other end is an air outlet end 162, which passes through the connecting tube 11 and the water storage chamber and extends out of the bottle cap body. The air outlet end 162 can be flush with the upper end surface of the bottle cap body.

[0030] Preferably, a portion of the heat-insulating reflux pipe 16 close to the air inlet end 161 is constructed as a spiral structure, the spiral structure portion is arranged in the heating pipe, and the other portion is a vertical through pipe. When the upward hot air passes through the spiral portion, the travel of the upward hot air is increased. At the same time, the spiral structure is arranged to ensure that the contact area between the hot air and the aluminum tube is larger, which can make the hot air reflux and ensure the heating effect.

[0031] In addition, since the outlet end 162 of the thermal insulation reflux pipe is exposed to the outside, dust or solid particles may enter the pipe over a long period of time, causing blockage of the thermal insulation reflux pipe and affecting the air outlet effect. Therefore, a layer of aluminum film can be set on the outlet end of the thermal insulation reflux pipe or the bottle cap body as a protection, which can be torn off when in use.

[0032] In this embodiment, the heating tube 12 adopts an aluminum tube with a wall thickness of 1-2 mm, which can enhance the heat conduction effect. A 5-10 gram heating pack is installed at the bottom of the aluminum tube. The heating pack can be a common food heating pack on the market. The length of the aluminum tube is determined by the height of the drinking water bottle. The bottom end is 1-3 cm away from the bottom end of the drinking water bottle. Its diameter is in the range of 10-20 mm and is smaller than the diameter of the connecting tube. The material of the thermal insulation reflux tube is aluminum or tube, and its own size is determined according to the size of the bottle.

[0033] The heating bottle cap of the present application is suitable for heating bottled water below 5°. When the water temperature is lower than 5°, the heating pack will not react. When in use, first unscrew the top cover 17, then press the squeezing rod 15, and drive the glass ball 13 downward through the squeezing rod 15, thereby opening the water inlet 103, so that all the water in the water storage chamber 102 is injected into the bottom end of the heating tube 12, and chemically reacts with the heating pack to continuously generate a large amount of hot steam. After all the water in the water storage chamber 102 has flowed out, release the squeezing rod 15, and the spring 14 rebounds to hold the glass ball 13, blocking the inlet. The water inlet forces the upward rushing hot steam to pass through the thermal insulation reflux pipe 16. At this time, most of the heat is absorbed by the aluminum tube, the aluminum tube becomes hot, and heat exchange occurs with the drinking water in the drinking water bottle. The drinking water in the drinking water bottle then becomes hot and warms up. Within 5-15 minutes, the temperature is raised to a comfortable drinking temperature zone. Unscrew and remove the integrated bottle cap, and you can drink the heated drinking water. When a part of the hot air entering the thermal insulation reflux pipe 16 passes through the spiral part, the travel of the upward rushing hot air is increased, so that the hot air can reflux, and a part of it is discharged through the air outlet end 162 to prevent damage to the bottle cap. Example

[0034] like Figure 5 As shown, this embodiment provides a bottled drinking water heating bottle cap, whose main structure is roughly the same as that in Embodiment 1, except that the structures of the sealing member and the extrusion member are different. In this embodiment, the sealing member adopts an aluminum film, and the water inlet 103 is also a circular hole, in which an aluminum film is encapsulated, and the structure of the glass ball and the spring in Embodiment 1 is discarded. The extrusion member also adopts an extrusion rod. Different from Embodiment 1, the bottom end of the extrusion rod 15 has a needle-shaped puncturing portion 152, and a sealing portion 153 of a cylindrical structure is arranged above the puncturing portion, and the sealing portion 153 has an external thread, and the water inlet 103 has a thread, so that the sealing portion can be threadedly connected to the water inlet.

[0035] When in use, unscrew the top cover 17, then press the squeezing rod 15, move the squeezing rod 15 downward to puncture the aluminum film, open the water inlet 103, and allow all the water in the water storage chamber 102 to be injected into the bottom end of the heating tube 12 to react chemically with the heating bag. After all the water in the water storage chamber 102 has flowed out, the squeezing rod is rotated to tighten the sealing part and the water inlet to complete the sealing of the water inlet.

[0036] Of course, the sealing part 153 and the water inlet 103 may also not be connected by threads. For example, the sealing part may adopt a truncated cone structure with a certain taper and made of rubber. After piercing the aluminum film, continue to press the extrusion rod downward to complete the sealing of the water inlet through the sealing part made of rubber.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
