Description

Technical Field

[0001] The utility model relates to the technical field of beauty instruments, in particular to a liquid storage bin structure of a beauty instrument, an essence bottle and the beauty instrument. Background Art

[0002] At present, some beauty devices are equipped with a liquid storage tank, which has a liquid storage chamber. The liquid storage chamber is used to store the liquid required in the beauty process, such as water or essence, so that users can hydrate their skin or inject essence during beauty. There are roughly two designs of existing liquid storage tanks. One of them is a disposable design, that is, the liquid storage tank is filled with essence when it leaves the factory, and it can only be discarded after the essence is used up. On the one hand, the liquid storage tank cannot be reused, resulting in increased costs; on the other hand, users cannot freely choose essence according to their skin conditions, which reduces the user experience. The other liquid storage tank will be designed with an openable cover, and users can freely pour the required liquid into the liquid storage chamber. Specifically, the liquid storage chamber can be exposed by opening the cover to pour the required liquid into the liquid storage chamber. On the one hand, when the cover is opened, a larger liquid injection port will be exposed. When the liquid storage tank or the beauty device is not placed correctly, it will inevitably cause the liquid to spill, thereby reducing the user experience. Secondly, the structure of the cover plate will inevitably require the design of a structure for how the cover plate is sealed when closed, which has the disadvantage of a more complex structure, while also increasing the cost of the product and the difficulty of assembly, and the sealing reliability of the cover plate is not high.

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] See also Figure 1 The present embodiment provides a liquid storage tank structure of a beauty instrument. The liquid storage tank can be arranged in the beauty instrument, or can be designed to be detachably connected to the main body of the beauty instrument. The liquid storage tank structure mainly includes a main body 1 and a liquid injection valve 2, wherein a liquid storage chamber 11 is arranged in the main body 1, and the liquid storage chamber 11 is used to store liquid required for beauty treatment, such as water or essence, so that the user can absorb water or essence. A liquid inlet 12 and a liquid outlet 13 are also arranged on the main body 1, and the liquid inlet 12 and the liquid outlet 13 are respectively connected to the liquid storage chamber 11. The liquid needs to be added to the liquid storage chamber 11 from the liquid inlet 12, and the liquid in the liquid storage chamber 11 is discharged outward through the liquid outlet 13 for the user to absorb. Among them, the injection valve 2 is a plastic part with deformation characteristics as a whole. The injection valve 2 is preferably a duckbill valve. The injection valve 2 blocks the liquid inlet 12 to prevent the liquid in the liquid storage chamber 11 from leaking out from the liquid inlet 12. The injection valve 2 is provided with an injection port 21, which is in a normally closed state when not opened by external force.

[0041] See also Figure 3 Before the user needs to add liquid to the liquid storage chamber 11 of this solution, the pre-prepared freeze-dried powder and the solvent can be mixed evenly to obtain the essence, and the obtained essence can be extracted using the injection tool 3. When the user needs to add liquid to the liquid storage chamber 11 of this solution, the injection tool 3 needs to be inserted into the injection valve 2, and the injection tool 3 opens the injection port 21 of the injection valve 2 and adds liquid to the liquid storage chamber 11. When the liquid is added, the injection tool 3 is pulled out from the injection valve 2, and the injection port 21 will automatically close. With this solution, during the process of adding liquid, whether the liquid storage tank or the beauty instrument is placed horizontally or accidentally touched and tipped over, the liquid in the liquid storage chamber 11 will not leak out, thereby greatly improving the user's experience. Furthermore, since the injection port 21 of the injection valve 2 has the characteristic of automatic closure after the liquid is added, the structure of the liquid storage tank of this solution is simpler, which reduces the cost of the product and reduces the difficulty of assembly, and the structure of the injection valve 2 has higher sealing reliability.

[0042] Please also read Figure 1 and Figure 4 The injection valve 2 can be optionally entirely accommodated in the liquid storage chamber 11. In order to enable the injection tool 3 to be inserted into the injection valve 2, the main body 1 is provided with an opening 14 at a position adjacent to the injection valve 2. The opening 14 is designed to be directly opposite to the injection port 21 of the injection valve 2, so that the injection tool 3 can be inserted into the injection valve 2 by extending into the opening 14, that is, the injection port 21 can be opened by inserting the injection tool 3 into the opening 14. By adopting such a design, the injection valve 2 can be hidden in the liquid storage chamber 11 while realizing the function of the injection tool 3 being able to replenish liquid into the liquid storage chamber 11, thereby improving the appearance of the liquid storage tank.

[0043] Please refer again Figure 1 The main body 1 is provided with an air hole 15, which connects the liquid storage chamber 11 with the outside world, so that the air pressure inside the liquid storage chamber 11 can be balanced with the outside air pressure. Specifically, when the liquid inside the liquid storage chamber 11 is gradually consumed, the air pressure inside the liquid storage chamber 11 will become smaller, and at this time, the outside air will enter the liquid storage chamber 11 along the air hole 15, ensuring that the air pressure inside the liquid storage chamber 11 can be increased to balance with the outside air pressure, avoiding the phenomenon that the liquid cannot be discharged outward due to the air pressure inside the liquid storage chamber 11 being too small, that is, ensuring the stability and reliability of the liquid discharge outward. When the liquid is replenished into the liquid storage chamber 11, the gas in the liquid storage chamber 11 will be discharged outward along the air hole 15, avoiding the phenomenon that the liquid discharge is abnormal due to the excessive air pressure inside the liquid storage chamber 11 after the liquid is replenished. Optionally, the aperture of the pore 15 is 0.5 mm-1.5 mm. If the aperture of the pore 15 is too small, the air pressure in the liquid storage chamber 11 and the external air pressure will reach equilibrium more slowly. If the aperture of the pore 15 is too large, the risk of leakage will increase.

[0044] In this embodiment, in order to reduce the risk of the liquid in the liquid storage chamber 11 leaking outward along the air hole 15, the air hole 15 can be as follows: Figure 1 The design shown is in the top area, because the liquid in the liquid storage chamber 11 is located below the liquid storage chamber 11 due to its own gravity, as long as the height of the air hole 15 is higher than the liquid surface, the risk of liquid leaking out from the air hole 15 can be reduced. In addition, when injecting liquid, since a large number of bubbles will be formed at the liquid inlet 12, in order to prevent the bubbles from spreading into the air hole 15 and blocking the air hole 15, and also to prevent the liquid from splashing into the air hole 15 and leaking out along the air hole 15 due to the bursting of bubbles, the air hole 15 can be as Figure 1 The design shown is arranged away from the liquid inlet 12, or the air hole 15 can also be as Figure 5As shown, it is arranged close to the liquid inlet 12. However, when the air hole 15 is arranged close to the liquid inlet 12, a blocking rib 16 needs to be arranged in the liquid storage chamber 11. The blocking rib 16 is used to separate the air hole 15 and the liquid inlet 12 to prevent the bubbles at the liquid inlet 12 from spreading to the air hole 15 and to prevent the liquid from splashing into the air hole 15 when the bubbles burst.

[0045] Please also refer to Figure 3 and Figure 5 The liquid storage chamber 11 is provided with a convex column 17, and a gas channel 171 is provided in the convex column 17. The gas channel 171 connects the liquid storage chamber 11 with the outside, and the above-mentioned air hole 15 is formed at one end of the gas channel 171. The convex column 17 extends in a direction close to the liquid inlet 12, so that the air hole 15 is close to the liquid inlet 12, and the above-mentioned blocking rib 16 separates the convex column 17 and the liquid inlet 12. Through such a design, the outer wall of the convex column 17 can block the liquid in the liquid storage chamber 11, solve the problem of liquid leaking outward along the air hole 15 when the liquid storage tank is placed tilted, and further reduce the risk of leakage.

[0046] Please refer again Figure 3 The liquid storage tank structure also includes a liquid absorbing member 4 connected to the main body 1. The liquid absorbing member 4 has liquid absorbing properties and air permeability properties. For example, the liquid absorbing member 4 is a sponge. The liquid absorbing member 4 is arranged on the path where the air hole 15 is connected to the outside. The liquid absorbing property of the liquid absorbing member 4 can absorb the liquid leaked from the air hole 15 to the outside, and prevent the liquid from leaking to the outside or leaking to other parts of the beauty instrument and causing damage to the beauty instrument. That is, by setting the liquid absorbing member 4, the risk of liquid leakage can be further reduced. The air permeability of the liquid absorbing member 4 allows the air pressure inside the liquid storage chamber 11 to be consistent with that of the outside, thereby ensuring the high stability and high reliability of the liquid discharge in the liquid storage chamber 11.

[0047] Please also read Figure 1 and Figure 2The liquid storage tank of the present scheme also includes an atomizing nozzle 5, which specifically includes a liquid outlet part 51 and a sleeve part 52. The liquid outlet part 51 is provided with a mist outlet hole 511, and the mist outlet hole 511 is connected to the liquid outlet port 13 of the main body 1. The sleeve part 52 is sleeved on the outer periphery of the liquid outlet part 51 and forms an air outlet 53 between the liquid outlet part 51 and the liquid outlet part 51. The air outlet 53 and the mist outlet hole 511 are arranged adjacent to each other. An air supply channel 18 connected to the air outlet 53 is also provided in the main body 1. When gas is pumped into the air supply channel 18, the gas will flow out from the air outlet 53. Since the air outlet 53 and the mist outlet hole 511 are arranged adjacent to each other, and the airflow output by the air outlet 53 forms a negative pressure near the mist outlet hole 511, and since the air pressure at the mist outlet hole 511 is lower than the air pressure in the liquid storage chamber 11, the essence in the liquid storage chamber 11 is discharged from the mist outlet hole 511 in the form of mist along the mist outlet hole 511, and finally penetrates into the human skin to achieve the absorption of the essence. Through such a design, the liquid storage tank can realize the function of atomizing and discharging the essence. The use of pneumatic misting can greatly reduce the particle size of the spray liquid, improve the spray efficiency, improve the atomization uniformity of the essence, and improve the absorption effect of the essence. Optionally, the liquid outlet 51 is sealed and connected to the main body 1, and the sleeve 52 is also sealed and connected to the main body 1, so that the gas in the air supply channel 18 can only be discharged from the air outlet 53, and the gas in the air supply channel 18 cannot be discharged from the gap between the liquid outlet 51 and the main body 1 and the gap between the sleeve 52 and the main body 1. Optionally, the air outlet 53 is annularly arranged around the outer periphery of the mist outlet hole 511. Through such a design, there is gas with a relatively high flow rate in the entire periphery of the mist outlet hole 511, so that a uniform and stable low-pressure state is formed around the outer periphery of the mist outlet hole 511, ensuring that the essence in the liquid storage chamber 11 can be sprayed outward from the mist outlet hole 511 in the form of mist, reducing the possibility of both mist essence and liquid essence being sprayed outward at the mist outlet hole 511, and also solving the problem of intermittent spraying of the essence at the mist outlet hole 511, thereby improving the stability of the essence being sprayed at the mist outlet hole 511.

[0048] See also Figure 1 The liquid storage chamber 11 includes a liquid storage cavity 111 and a liquid outlet channel 112 which are connected. The liquid storage cavity 111 is preferably annularly surrounding the outer periphery of the liquid outlet channel 112. The above-mentioned liquid outlet port 13 is formed at the end of the liquid outlet channel 112. The aperture of the liquid outlet channel 112 is 0.5mm-2mm. If the aperture of the liquid outlet channel 112 is too small, it is not conducive to the outward mist. If the aperture of the liquid outlet channel 112 is too large, the risk of leakage is increased, and it also has a certain impact on the spray effect.

[0049] The present application also provides a beauty instrument, which includes a main body 6 and an essence bottle 7 detachable from the main body 6. The essence bottle 7 includes the above-mentioned liquid storage structure. When the essence bottle 7 only has the function of storing liquid and allowing the liquid to be discharged outward, the liquid storage structure is the essence bottle 7. By designing a detachable essence bottle 7, the user can take out the essence bottle 7 and then add liquid to the liquid storage chamber 11. That is, the user does not need to hold the entire beauty instrument with a large volume when adding liquid to the liquid storage chamber 11, so that it is more convenient for the user to perform the operation of adding liquid, thereby improving the user's experience. In this embodiment, in addition to having the function of storing liquid and allowing the liquid to be discharged outward, the essence bottle 7 also integrates a microneedle device 8, which is connected to the main body 1. The microneedle device 8 can be a microneedle wafer or other forms of microneedles. The microneedle wafer can be understood as a plurality of nano-level microneedles arranged on a wafer. Each microneedle can stimulate the skin of the human body to open the internal channel of the skin, so that the user can better absorb the essence. By integrating the microneedle device 8 on the essence bottle 7, the overall size of the beauty instrument is made smaller, which is more convenient for users to hold or store. It is additionally explained here that the connection between the microneedle device 8 and the main body 1 can be either a fixed connection or a sliding connection. When the microneedle device 8 and the main body 1 are fixedly connected, the user needs to manually apply force to make the microneedle device 8 stimulate the skin. When the microneedle device 8 and the main body 1 are slidingly connected, a driving device can be set in the host 6, and the driving device drives the microneedle device 8 to automatically reciprocate and vibrate so that the microneedle device 8 stimulates the human skin. In addition, when the above-mentioned atomizing nozzle 5 is provided in the essence bottle 7, an air pump is also required in the host 6. The air pump is used to pump gas into the above-mentioned air supply channel 18. At this time, the liquid in the essence bottle 7 realizes the function of atomization and spraying.

[0050] For more details, see Figure 4 The essence bottle 7 is provided with a first foolproof structure 71, see Figure 7 and Figure 8 The host 6 is provided with a second foolproof structure 61. When the essence bottle 7 and the host 6 of the beauty instrument are connected to each other, the first foolproof structure 71 and the second foolproof structure 61 are connected in cooperation, and the air hole 15 is as Figure 1 Shown or Figure 5 As shown, the air hole 15 is located at the top, and the air hole 15 is connected to the top area of ​​the liquid storage chamber 11. At this time, the liquid in the liquid storage chamber 11 is located below the liquid storage chamber 11 due to its own gravity, and the height of the air hole 15 is higher than the liquid surface, thereby reducing the risk of liquid leaking out of the air hole 15. Preferably, the first fool-proof structure 71 is designed as a rib structure, and the second fool-proof structure 61 is designed as a slot structure that cooperates with the rib.

[0051] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
