[0029] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] like Figure 1-3 As shown, in this embodiment, the water replenishing device includes a water replenishing liquid bottle 1 and a main body 3. A buckling structure along the circumferential direction is provided at the joint between the water replenishing liquid bottle 1 and the main body 3 (the buckling element 10 on the water replenishing liquid bottle is as shown in FIG. Figure 3 As shown, the snap-fit ​​elements on the main body are not shown), and the two can be installed and removed by rotation.

[0031] like Figure 4 , 5 As shown, in this embodiment, the water replenishment liquid bottle 1 is used to provide water, and mainly includes a bottle body 11, a piston 12, a spring 13, and a piston seal 14. The bottle body 11 is used to store liquid, and includes a bottle shell 111 and a bottle seat 112. The bottle shell 111 and the bottle seat 112 are fixed to each other, and a bottle body sealing ring 15 is used to form a sealing fit. A vent hole 113 is provided on the upper part of the bottle shell 111, and a waterproof and breathable membrane 114 is attached to the vent hole 113.

[0032] The bottle seat 112 is provided with a water injection port 115 in the center, and a cylindrical protrusion 116 is provided around the water injection port 115 in the lower center. The inside of the cylindrical protrusion 116 is connected to the water injection port 115 for accommodating the piston 12 and the spring 13. The outer wall of the cylindrical protrusion 116 is provided with a water replenishing liquid bottle sealing ring 16.

[0033] The piston 12 is provided with a stopper larger than the rod body at both the upper and lower ends. The piston seal 14 is installed at the upper end of the piston 12 and is limited by the upper stopper. The piston seal 14 is located above the water injection port 115. The spring 13 is located between the piston seal 14 and the stopper at the lower end of the piston 12. In a natural state, the spring 13 pulls the piston seal 14 against the top to close the water injection port 115, and the piston 12 can overcome the elastic force of the spring 13 and move upward after receiving an upward force, so that a gap is generated between the piston seal 14 and the water injection port 115 for the water stored in the bottle to pass through.

[0034] like Figure 6-11 As shown, in this embodiment, the main body 3 mainly includes a shell 31, a cover 32, a base 33, a converter 34, a nozzle 35, a bottom cover 36, a bracket 37, and an air supply mechanism 38.

[0035] The housing 31 is in the shape of a handle, so that the water replenishing device is portable and handheld, which is convenient to carry and use. The housing 31 includes a receiving portion 311 located at the upper part and a hand-held portion 312 located at the lower part. The housing 31 is open at both ends, and the interior is separated by a partition 313. The middle of the partition 313 is provided with a through hole 314 (such as Fig. 9 shown).

[0036] The cover 32 covers the opening of the receiving portion 311, so that an upper receiving space is formed between the cover 32 and the partition 313. The base 33, the nozzle 34, and the converter 35 are received in the upper receiving space. A through hole is provided in the center of the cover 32, and a circular protrusion 321 is provided around the through hole at the bottom.

[0037] The upper end of the base 33 is open, the side is provided with a docking hole 331, the lower end is provided with an air inlet 332, and the other wall parts are closed structures. The upper end of the base 33 is sealed with the cover 32 through the cover sealing ring 39. The wall part with the docking hole 331 on the side is in the shape of a vertical flat plate to cooperate with the nozzle 34. The outer side of the vertical flat plate wall is also equipped with a bell mouth 40 for sticking to the user's face when replenishing water. The front part of the docking hole 331 is in the shape of a truncated cone, and the rear part is in the shape of a spherical segment.

[0038] The converter 34 includes a vertical portion 341 arranged vertically in a cylindrical shape and a horizontal portion 342 arranged horizontally in a circular tube shape. The vertical portion 341 is connected to the inside of the horizontal portion 342 so that the liquid can flow from the vertical portion 341 to the horizontal portion 342. A disc-shaped nozzle connection portion 343 is also provided at the end of the horizontal portion 342. After assembly, the vertical portion 341 is inserted into the annular protrusion 321 of the cover body 32, and the two are sealed together through the converter sealing ring 41. The cylindrical protrusion 116 at the bottom of the water replenishing liquid bottle 1 is inserted into the vertical portion 341, and the two are sealed together through the water replenishing liquid bottle sealing ring 16.

[0039] In this embodiment, there are five nozzles 35 fixed on the fixing plate 42, and the nozzles 35 are connected. The five nozzles 35 are installed on the nozzle connecting portion 343 through the fixing plate 42. In other embodiments, the nozzles 35 can also be provided with different numbers, such as one (such as Fig.12 shown), or other quantities.

[0040] The nozzle 35 is a retractable hollow structure, and a liquid flow channel 351 is provided in the center. In this embodiment, the nozzle 35 is made of silicone material, and includes an integrally formed fixed portion 352, an elastic portion 353, and a movable portion 354. The fixed portion 352 is fixed to the fixed plate 42 to fix the nozzle 35, and the elastic portion 353 connects the fixed portion 352 and the movable portion 354 and has elasticity, so that the movable portion 354 forms a retractable structure, and the movable portion 354 is located at the front end of the nozzle 35. The front end of the movable portion 354 is in a truncated cone shape with a small front and a large rear, and matches the truncated cone shape of the docking hole 331.

[0041] The bottom cover 36 is installed at the bottom of the housing 31. The bottom cover 36, the hand-held part 312, and the partition plate 313 form a lower receiving space. The bracket 37 and the air supply mechanism 38 are received in the lower receiving space.

[0042] The bracket 37 is fixed on the housing 31 to support other components. The air supply mechanism 38 includes a power supply 381 (a battery is used in this embodiment) and an air pump 382. The power supply 381 is connected to the air pump 382 to supply power to the air pump 382. The power supply 381 and the air pump 382 are fixed on the bracket 37 respectively. A notch 3121 is provided on one side of the handheld portion 312. Inside the notch 3121, a main board 43 is installed on the bracket 37 and electrically connected to the air pump 382. A button 44 is located in the notch 3121 and is installed on the main board 43 to operate the main board 43 and control the air pump 382 through the main board 43.

[0043] The air pump 382 is provided with an air outlet nozzle 3821 at the upper end, which is inserted into the air inlet hole 332 of the base 33 and is sealed with the wall of the air inlet hole 332 through the air pump sealing ring 45. In this way, a gas chamber is formed between the base 33, the cover 32, the air pump air outlet nozzle 3821, and the converter 34. The gas generated by the air pump 382 fills the gas chamber and is ejected toward the gap between the front end of the nozzle 35 and the docking hole 331 of the base 33. Because the nozzle 35 is a retractable hollow structure, after assembly, the front end of the nozzle 35 abuts against the docking hole 331, so that the gap between the front end of the nozzle 35 and the base 33 forms a gas injection channel.

[0044] The prior art forms a gas injection channel through a gap between the front end of the nozzle and the external hole. Since there are inevitably manufacturing tolerances and assembly tolerances in the production of the gap, in order to ensure smooth passage of the gas, the gap needs to be designed to be relatively large. In addition, due to the manufacturing tolerances and assembly tolerances, the gaps in the final product will vary in size, resulting in small and unstable injection pressure and speed.

[0045] Therefore, the front end of the nozzle 35 of this embodiment abuts against the docking hole 331 so that the gap between the front end of the nozzle 35 and the base 33 forms a gas injection channel. Compared with the gap between the front end of the nozzle and the external hole in the prior art, a smaller gas injection channel can be obtained, providing a larger gas injection pressure and speed, and then providing a larger and more stable liquid injection pressure and speed, significantly improving the spray effect. In addition, because the gap between the front end of the nozzle and the base can be set very small, when multiple nozzles are set, each nozzle can obtain a larger gas injection pressure and speed, ensuring a better spray effect.

[0046] At the same time, the setting of the retractable hollow structure can also make the front end of the nozzle 35 slightly displaced backward by the air pressure under extreme conditions of excessive air pressure, thereby releasing the air pressure and playing a role in overpressure protection.

[0047] The front part of the docking hole 331 of the base 33 is in the shape of a truncated cone with a smaller front part and a larger rear part, and the rear part is in the shape of a spherical segment, while the front end of the nozzle movable part 354 is in the shape of a truncated cone with a smaller front part and a larger rear part, and matches the truncated cone shape of the docking hole 331 of the base 33, so that a gap is formed between the front end of the nozzle 35 and the base 33 at the contact point, and a gap is formed behind the gap, so that the thrust generated by the gas on the nozzle movable part 354 is mainly concentrated in the spherical segment-shaped area behind the docking hole 331, which is conducive to controlling and adjusting the thrust of the gas pressure on the front end of the nozzle 35.

[0048] In this embodiment, the front end of the nozzle 35 and the external hole 331 are provided with a plurality of radial grooves (not shown) on the mating surface to form a gap as a gas injection channel. The radial grooves can be provided at the front end of the nozzle 35, or at the wall of the docking hole 331, or at both. The use of radial grooves to form a gas injection channel can obtain a smaller gas injection channel and is easy to process.

[0049] In the above-described embodiment of the water replenishing device, the base is used as an external component to form a liquid spraying structure with the nozzle. Of course, in other embodiments of the water replenishing device, the liquid spraying structure can also use other components as external components to form a liquid spraying structure with the nozzle. In addition, the liquid spraying structure of the present invention can also be applied to other products besides the water replenishing device, including various humidification and dust removal products.
