[0050] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0051] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0052] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0053] The following is in conjunction with the appendix Figure 1-9 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0054] Please refer to Figure 1 as well as Figure 2 This utility model provides a liquid level detection system for use in a beauty device, comprising a liquid cartridge body 1, a piston 2, a sensor 3, and a feedback module 4. The liquid cartridge body 1 has a liquid storage chamber 5 inside, and a light-transmitting window 6 for exposing the interior of the liquid storage chamber 5. The piston 2 is movably disposed in the liquid storage chamber 5 to push the beauty liquid from the liquid storage chamber 5 to the outside. The sensor 3 is opposite to the light-transmitting window 6 and detects the position of the piston 2 through the light-transmitting window 6. The feedback module 4 is connected to the sensor 3 to read the position signal of the sensor 3 and provide a prompt.

[0055] In some embodiments, the liquid bullet body 1 is a long and straight shell 11 structure with a hollow interior to form a liquid storage cavity 5. Accordingly, the liquid storage cavity 5 extends along the length direction of the liquid bullet body 1 to obtain a larger volume, which facilitates the storage of more beauty liquid. The piston 2 moves from one end to the other end in the liquid storage cavity 5 along the extension direction of the liquid storage cavity 5, thereby pushing the beauty liquid out.

[0056] In some embodiments, to facilitate the addition of beauty serum, an injection port 115 is provided on one side of the liquid bullet body 1, through which the beauty serum enters the storage chamber 5. Additionally, in some embodiments, an outlet 116 is provided at one end of the liquid bullet body 1. Under the push of the piston 2, the beauty serum can flow out from the outlet 116, achieving a dispensing effect. Alternatively, in some embodiments, an atomizing element, such as an electronic atomizing device, can be provided at one end of the liquid bullet body 1. The beauty serum can be atomized and dispensed through the atomizing element. No specific restrictions are placed on the addition and dispensing methods of the liquid bullet body 1. It is understood that because the flow direction of the beauty serum is consistent with the movement direction of the piston 2, a stable dispensing effect can be achieved. For ease of description, the displacement direction of the piston 2 is defined as the dispensing direction.

[0057] In some embodiments, the light-transmitting window 6 is located at the other end of the liquid bullet body 1 away from the liquid outlet 116. Specifically, an assembly hole may be provided at the other end of the liquid bullet body 1. The light-transmitting window 6 is made of a transparent material, such as transparent plastic or transparent glass. The light-transmitting window 6 is snapped into the inner edge of the assembly hole to realize the setting of the light-transmitting window 6 on the liquid bullet body 1. The sensing signal of the sensor 3 can enter the liquid bullet body 1 through the light-transmitting window 6 and act on the piston 2, and can also bounce off the piston 2 and be fed back to the sensor 3 through the light-transmitting window 6 to realize distance detection.

[0058] The light-transmitting window 6 is made of a transparent material, providing a sealed space when the power source for piston 2 is selected as a fluid power source. Optionally, the light-transmitting window 6 can also be configured as a through hole (i.e., the aforementioned mounting hole can be directly used as the light-transmitting window 6). The sensor 3 detects the displacement of piston 2 through the through hole. In this case, the power source for piston 2 can also be an electric power source. No specific restrictions are placed on the specific configuration of the light-transmitting window 6. It is understood that when the light-transmitting window 6 is made of a transparent material, a material with a light transmittance of less than 100% can be selected, as long as it meets the distance measurement requirements of sensor 3. No limitations are placed on the material of the light-transmitting window 6.

[0059] The liquid level detection system provided in this application embodiment provides a light-transmitting window 6 as a basis for the alternating transmission of signals on the inner and outer sides of the liquid bullet body 1. By aligning the sensor 3 with the light-transmitting window 6, the position of the piston 2 can be accurately detected, thereby generating an accurate position signal. The position signal is read through the feedback module, allowing the user to more conveniently obtain the remaining amount of beauty liquid through the specific position of the piston 2. The detection data is accurate, reliable, and convenient, solving the problem of the inability to identify the remaining amount of beauty liquid inside the liquid bullet body 1.

[0060] In some embodiments, refer to Figure 2The feedback module 4 includes a main control chip 41 and a prompting element 42. The main control chip 41 is connected to the sensor 3 to acquire position signals and convert them into recognition signals. The prompting element 42 is connected to the main control chip 41 to acquire recognition signals and prompt the remaining liquid volume. The prompting element 42 can be a display screen, an indicator light, and / or a voice element.

[0061] Among them, sensor 3 has an output terminal, main control chip 41 has an output terminal and a receiving terminal, prompting element 42 has a receiving terminal, the output terminal of sensor 3 is electrically connected to the receiving terminal of main control chip 41, and the output terminal of main control chip 41 is electrically connected to the receiving terminal of prompting element 42.

[0062] At this time, sensor 3 obtains a position signal by detecting the position of piston 2. The position signal is sent from the output of sensor 3 to the receiving end of main control chip 41. Based on the position signal, main control chip 41 calculates and processes it to generate an identification signal. The identification signal is then sent from the output of main control chip 41 to the receiving end of prompting element 42. Prompting element 42 responds to the identification signal, thereby enabling the user to know the remaining liquid volume information.

[0063] When the prompting element 42 is a display screen, the display screen can show the percentage of the remaining liquid, thereby indicating the amount of remaining liquid.

[0064] When the indicator element 42 is a signal light, for example, multiple signal lights can be set up in an arrangement. The main control chip 41 controls the number of lights that are lit to remind the user of the current liquid level. Alternatively, the signal lights can be set to light elements of different colors, emitting red or green light to remind the user of the remaining liquid level.

[0065] When the prompt element 42 is a voice element, the voice element can be a speaker element. At this time, a storage module can be set inside the main control chip 41. The storage module records the corresponding voice information for different liquid volume levels. When the liquid volume reaches the threshold of the corresponding liquid volume, the main control chip 41 controls the voice element to broadcast the corresponding voice information, so that the user can know the remaining liquid volume.

[0066] Based on the above settings, in practical applications, the prompting element 42 can be any of the above prompting methods, or a combination of any two of the above prompting methods, or a combination of the above three prompting methods, which can meet different usage needs. The specific setting of the prompting element 42 is not specifically limited here. In the end, a solution is obtained that allows users to intuitively know the remaining liquid volume. The setting is flexible and the information is accurately transmitted, and the user experience is significantly optimized and improved.

[0067] In some embodiments, the sensor 3 includes at least one of the following: a laser sensor 3, an infrared sensor 3, or an ultrasonic sensor 3. The laser sensor 3 can obtain a distance value by emitting a laser and acquiring the time of laser reflection through a photosensitive element, thereby obtaining an accurate position signal.

[0068] The infrared sensor 3 can obtain distance values ​​by emitting infrared light and acquiring the time of laser reflection through a photosensitive element, and can also obtain accurate position signals.

[0069] In addition, the ultrasonic sensor 3 can also obtain an accurate position signal by emitting ultrasonic signals and inferring the distance by judging the time difference when the receiver receives the ultrasonic waves.

[0070] Based on the above settings, the laser sensor 3, infrared sensor 3, or ultrasonic sensor 3 all have accurate displacement detection functions, can obtain accurate position signals, and meet the requirements of actual working conditions.

[0071] In some other embodiments, the sensor 3 can also be a Hall sensor 3. In this case, a magnet needs to be installed on the piston 2. When the piston 2 is displaced, the Hall sensor 3 can sense the magnitude of the magnetic field of the magnet, thereby knowing the displacement distance of the piston 2, and thus also obtaining the position signal.

[0072] It is understood that regardless of the structure of sensor 3, as long as it adopts the principle of detection using physical properties, it should be included in the scope of interpretation of this application.

[0073] Reference Figure 3 and Figure 4 To improve the liquid dispensing effect, in some embodiments, an atomizing head 7 is also included. The atomizing head 7 is disposed at one end of the liquid bullet body 1. One end of the liquid bullet body 1 is also provided with a liquid outlet 116. The liquid outlet 116 is connected to the atomizing head 7. The atomizing head 7 is used to atomize the beauty liquid into atomized particles.

[0074] Based on the above settings, the outlet 116 can connect the atomizing head 7 to the liquid storage chamber 5. At this time, by setting the atomizing head 7, the beauty essence can be atomized into fine atomized particles, so that the beauty essence can be evenly applied to the user's skin, and the beauty effect is optimized and improved.

[0075] In some embodiments, the liquid storage cavity 5 extends along the length of the liquid bullet body 1, the piston 2 slides along the length of the liquid storage cavity 5, and the light-transmitting window 6 is located at the other end of the liquid bullet body 1.

[0076] Specifically, the front end of the liquid bullet body 1 is provided with a mounting hole 101, which is connected to the liquid storage chamber 5. The outer edge contour of the atomizing head 7 is adapted to the opening contour of the mounting hole 101. At this time, the atomizing head 7 can be pressed into the mounting hole 101, and the atomizing head 7 can be fixedly installed by using the transition fit or interference fit between the mounting hole 101 and the atomizing head 7.

[0077] It is understandable that the mounting hole 101 at this time is equivalent to the liquid outlet 116. The mounting hole 101 provides a mounting position for the atomizing head 7 so as to connect the atomizing head 7 to the liquid storage chamber 5.

[0078] Based on the above configuration, the liquid storage cavity 5 extending along the length of the liquid bullet body 1 has a larger volume ratio, which can make full use of the internal space of the liquid bullet body 1. At this time, by sliding the piston 2 along the length of the liquid storage cavity 5, the beauty liquid can be smoothly delivered in a straight direction. The light-transmitting window 6 located at the other end of the liquid bullet body 1 can also conveniently observe the piston, thereby obtaining accurate distance detection data. The structural design is reasonable.

[0079] In some embodiments, refer to Figure 3 The atomizing head 7 has an atomizing port 71, an air outlet channel 72, and a liquid outlet channel 73.

[0080] The atomizing port 71 is connected to the air outlet channel 72, and the air outlet channel 72 is used to access the external airflow. The liquid outlet channel 73 is connected to the liquid storage chamber 5 through the liquid outlet 116, and the liquid outlet channel 73 is used to guide the beauty liquid into the air outlet channel 72 for atomization.

[0081] Specifically, Figure 3 The dashed arrow in the middle indicates the direction of liquid discharge. The atomizing port 71 is located in front of the gas outlet channel 72 in the direction of liquid discharge. At least part of the gas outlet channel 72 is located in front of the liquid outlet channel 73 in the direction of liquid discharge. The liquid outlet channel 73 is located in front of the liquid storage chamber 5 in the direction of liquid discharge.

[0082] Based on the above configuration, piston 2 pushes the beauty liquid from the reservoir 5 to the outlet channel 73. The beauty liquid enters the air outlet channel 72 through the outlet channel 73. The outlet channel 73 can cut the beauty device into fine atomized particles and finally spray them out from the atomization port 71. During this process, the beauty liquid flows out in a straight line, the liquid outlet is smooth and not easily obstructed by the structure, which can effectively improve the stability of the liquid outlet and the atomization effect.

[0083] In one embodiment, reference continues Figure 3 The air outlet passage 72 includes an annular constriction section 721 and a straight section 722.

[0084] The annular constriction section 721 is connected to an external gas source, and the straight section 722 is connected to the annular constriction section 721. The straight section 722 is located in front of the annular constriction section 721 in the liquid outlet direction. The annular constriction section 721 is arranged around the periphery of the liquid outlet channel 73, and the liquid outlet channel 73 extends into the straight section 722.

[0085] Specifically, the annular constriction section 721 gradually narrows in width along the liquid outlet direction. When the airflow enters the annular constriction section 721, its speed gradually increases and it enters the straight section 722. In addition, the high-speed airflow reaches the straight section 722 and forms a negative pressure area near the outlet of the liquid outlet channel 73, thereby drawing the beauty essence from the liquid outlet channel 73 into the straight section 722.

[0086] Based on the above settings, the beauty liquid is fully cut by the airflow in the straight section 722 to form multiple fine atomized particles, achieving a fine and uniform atomization function.

[0087] In some embodiments, refer to Figure 4 The liquid bullet body 1 also includes an airflow channel 102, a vent 103, and an air inlet 104.

[0088] An airflow channel 102 is formed inside the liquid bullet body 1. One end of the airflow channel 102 is connected to the atomizing head 7. A vent 103 is provided on the inner wall of the airflow channel 102. The vent 103 is connected to the rear side of the liquid storage chamber 5. The vent 103 is used to guide the airflow from the airflow channel 102 into the liquid storage chamber 5. An air inlet 104 is connected to the other end of the airflow channel 102. The air inlet 104 is used to access the external airflow.

[0089] Based on the above configuration, the air inlet 104 facilitates connection to an external air source, allowing airflow to smoothly enter the airflow channel 102. Furthermore, by connecting the airflow channel 102 to the atomizing head 7 and the liquid storage chamber 5 respectively, airflow is directed into both the atomizing head 7 and the liquid storage chamber 5 during the atomization of the beauty serum. This allows for both accelerated airflow atomization of the beauty serum and simultaneous increase in liquid output pressure, achieving a reasonable balance between liquid and gas output, which is beneficial for achieving a fine atomization effect.

[0090] In some embodiments, the atomizing head 7 can also be an electronic atomizing device, such as an ultrasonic atomizing device, which is equipped with an atomizing plate and a beauty essence guide rod. More specifically, one end of the beauty essence guide rod is connected to the atomizing plate, and the other end extends into the liquid outlet 116 to guide the beauty essence to the atomizing plate. When the atomizing plate is energized, high-frequency resonance can be achieved, thereby atomizing the beauty essence, thus realizing the atomized liquid dispensing function of the beauty essence.

[0091] In some embodiments, refer to Figure 4 and Figure 5The liquid bullet body 1 includes a shell 11, a rear end cover 12 and a front end cover 13. A partition 14 is integrally connected inside the shell 11. The partition 14 divides the interior of the shell 11 into a liquid storage chamber 5 and a front chamber 105. The front chamber 105 is close to one end of the liquid bullet body 1, and the liquid storage chamber 5 is close to the other end of the liquid bullet body 1. The rear end cover 12 is located at the other end of the shell 11. A light-transmitting window 6 is located on the rear end cover 12. The rear end cover 12 closes the opening of the shell 11, thus forming a sealed liquid storage chamber 5.

[0092] In addition, the mounting hole 101 is provided on the partition 14. When the atomizing head 7 is installed in the mounting hole 101, the atomizing head 7 is also located in the front chamber 105. At this time, the front cover 13 is located at the end of the housing 11 away from the rear cover 12. The front cover 13 is located in front of the atomizing head 7 in the liquid outlet direction, and the front cover 13 is provided with a clearance hole 131, which is used to expose the atomizing port 71.

[0093] Based on this, the airflow channel 102 is embedded in the side wall of the housing 11 and is adjacent to the liquid storage chamber 5. The partition 14 has an air outlet 141. One end of the airflow channel 102 is connected to the front chamber 105 through the air outlet 141. At this time, the airflow channel 102 can guide the airflow into the front chamber 105. At the same time, combined with Figure 6 An air inlet 74 is provided on the side wall of the atomizing head 7, which is connected to the air outlet channel 72 and the front chamber 105 respectively.

[0094] Based on the above configuration, the airflow channel 102 can be arranged using the thickness of the housing 11, resulting in a compact structure. Under the joint guidance of the airflow channel 102, the front chamber 105, and the air inlet 74, external airflow can be introduced into the airflow channel. The airflow channel accelerates the airflow and mixes it with the beauty liquid, thereby cutting the beauty liquid to form atomized particles, which are finally sprayed out from the atomization port 71. This achieves excellent atomization effect while realizing a compact structure.

[0095] It should be added that, since the airflow channel 102 is located inside the side wall of the housing 11, it is also convenient for the vent 103 to communicate with the liquid storage chamber 5, thereby guiding the airflow to the rear side of the liquid storage chamber 5, generating a pushing force on the piston 2, which is beneficial to push the beauty device out of the liquid outlet channel, thereby improving the stability of the beauty liquid when it flows out.

[0096] It is understandable that the direction in which the beauty liquid flows out of the atomizing head 7 after atomization is defined as the front, and the opposite direction is defined as the rear. Based on this, the rear side of the liquid storage chamber 5 can be understood as the side of the liquid storage chamber 5 that is away from the liquid outlet direction.

[0097] In some embodiments, the air inlet 104 is disposed through the rear end cover 12 and is connected to the airflow channel 102. In this way, an external air source is connected to the air inlet 104, and airflow is introduced into the airflow channel 102 through the air inlet 104, thereby realizing the functions of liquid discharge and atomization.

[0098] Optionally, to facilitate the connection between the air inlet 104 and the air source, the rear cover 12 is also provided with an adapter. The adapter has a cylindrical structure, and the air inlet 104 is located on the adapter. This allows the adapter to be inserted into components such as air pipes, so that the air source can be connected to the air inlet 104, thereby achieving a connection effect. The connection is convenient and conducive to stabilizing the input airflow.

[0099] In some embodiments, refer to Figure 7 It also includes a mounting sleeve 8, which has a plug-in cavity 81. The plug-in cavity 81 is open at one end of the mounting sleeve 8. The liquid bullet body 1 is plugged into the plug-in cavity 81. The sensor 3 is disposed on the mounting sleeve 8.

[0100] Specifically, the opening contour of the insertion cavity 81 is adapted to the outer periphery contour of the liquid bullet body 1. When the liquid bullet body 1 is inserted into the insertion cavity 81, the inner wall of the mounting sleeve 8 abuts against the mounting sleeve 8. At this time, the liquid bullet body 1 can be positioned, making it less likely to loosen during installation and the structure more stable.

[0101] In addition, an interface is provided on the cavity wall opposite the opening of the insertion and extraction cavity 81. The interface is connected to the air source and is inserted into the adapter. When the liquid bullet body 1 is inserted into the mounting sleeve 8, the adapter is simultaneously inserted into the interface and communicates with the air source through the interface.

[0102] Furthermore, the sensor 3 is installed on the cavity wall opposite the opening of the insertion cavity 81, and the mounting sleeve 8 provides a fixed support for the sensor 3, so that the sensor 3 is installed firmly and can work stably.

[0103] In some embodiments, a vibration motor 9 is also included, the output end of which is connected to the mounting sleeve 8, and the vibration motor 9 drives the liquid bullet body 1 to reciprocate via the mounting sleeve 8.

[0104] Based on the above settings, the installation sleeve 8 can be driven to vibrate, which in turn drives the liquid bullet body 1 to vibrate synchronously. This allows the liquid bullet body 1 to pat the user's skin during use, thereby promoting the absorption of the beauty serum and optimizing and improving the skincare effect.

[0105] In some embodiments, refer to Figure 8This application also provides a water-light device, including the liquid level detection system described above, and a beauty device body 111. The sensor 3 and the feedback module 4 are disposed on the beauty device body 111, and the liquid bullet body 1 is fixedly disposed on the beauty device body 111, or the liquid bullet body 1 is detachably disposed on the beauty device body 111.

[0106] The beauty device body 111 is mainly used to provide installation positions for various mechanisms and components. For example, the beauty device body 111 can be equipped with circuit boards, main control chip 41, batteries, air sources and other components. Depending on the different functions of the beauty device, different components can be installed. Here, we do not limit the specific composition of the beauty device body 111, nor do we limit the specific functions of the beauty device body 111.

[0107] Based on this, the liquid bullet body 1 has multiple installation methods. When the liquid bullet body 1 is installed on the beauty device body 111 in a fixed setting manner, the liquid bullet body 1 can be directly fixed to the mounting sleeve 8, such as by threaded connection or welding. At this time, the installation of the liquid bullet body 1 can be realized, and the structure is relatively stable.

[0108] In addition, when the liquid bullet body 1 is detachably installed in the beauty device body 111, the liquid bullet body 1 can be inserted and removed into the installation sleeve 8, and an elastic fastening component for locking the liquid bullet body 1 is provided on the beauty device body 111. At this time, the liquid bullet body 1 can be replaced regularly by operating the elastic fastening component, making it more hygienic to use.

[0109] Based on the above settings, a beauty device that can accurately identify the amount of remaining liquid was obtained, providing users with a good user experience.

[0110] In some embodiments, following reference Figure 8 and Figure 9 One end of the liquid ball body 1 has microneedles, and the front end of the beauty device body 111 has an interface 113. The liquid ball body 1 is inserted into the interface 113. Several electrode elements 114 are around the interface 113. When the liquid ball body 1 is inserted into the interface 113, the electrode elements 114 and the microneedles combine to form a care surface.

[0111] In some specific embodiments, a microneedle chip 112 can be installed at the front end of the liquid bullet body 1. The microneedle chip 112 has microneedles, which can vibrate under the drive of the vibration motor 9, thereby opening the skin absorption channel and optimizing the promotion effect.

[0112] In addition, the connector 113 is located at the front end of the beauty device body 111, and the connector 113 is connected to the opening on the mounting sleeve 8. The liquid bullet body 1 is installed into the beauty device through the connector 113 to improve the compactness of the structure. On this basis, by setting electrode elements 114 around the connector 113, the electrode elements 114 can be electrically connected to the circuit board inside the beauty device body 111 to obtain power, and the discharge action is controlled by the main control chip 41. At this time, microcurrent can be output during care, thereby further opening the skin absorption channel and further optimizing and improving the penetration effect of beauty essence.

[0113] It is understandable that the treatment surface formed by the electrode element 114 and the microneedles can be a flat surface or an uneven curved surface. The function of the treatment surface is to fit into the skin so that the electrode element 114 and the microneedles can treat the skin at the same time. The specific outline of the treatment surface is not limited here.

[0114] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
