Description

Technical Field

[0001] This utility model relates to the field of skin treatment equipment technology, and in particular to a vacuum degree control system and skin treatment equipment. Background Technology

[0002] Existing skin treatment devices used in the medical aesthetics field require vacuum adsorption of the applicator onto the skin before applying high-frequency energy and / or injecting drugs. The high-frequency energy is radio frequency energy or ultrasound energy with a frequency of 1000Hz or higher. Since skin treatment devices are often used on different skin areas of the patient, and different skin areas have different requirements for the vacuum adsorption strength of the applicator.

[0003] Existing skin treatment equipment typically has an air inlet valve and a vacuum pump inside. The vacuum pump extracts the air entering from the air inlet valve to achieve a vacuum state. Since the opening degree of the air inlet valve is not adjustable, the vacuum degree of the skin treatment equipment is not adjustable, which makes it difficult for the applicator of the skin treatment equipment to meet the vacuum adsorption intensity of different skin areas. Utility Model Content

[0004] The main purpose of this invention is to propose a vacuum degree control system, which aims to solve the problem that the vacuum degree of existing skin treatment equipment is not adjustable, making it difficult for the applicator of the skin treatment equipment to meet the vacuum adsorption intensity of different skin areas.

[0005] To solve the above problems, this utility model proposes a vacuum degree control system, comprising:

[0006] A vacuum pump, one end of which is connected to the applicator via an airflow channel, and the other end of which is connected to the external space;

[0007] A pressure sensor, which is connected to the airflow channel, is used to detect the vacuum level of the airflow channel;

[0008] The valve body, one end of which is connected to the external space and the other end of which is connected to the airflow channel, and

[0009] The controller is electrically connected to the valve body, the pressure sensor, and the vacuum pump. The controller controls the opening of the valve body based on the monitoring value of the pressure sensor to control the amount of airflow entering the airflow channel.

[0010] In one embodiment, the valve body is a solenoid valve.

[0011] In one embodiment, the vacuum control system includes a filter element connected to the end of the valve body that communicates with the external space.

[0012] In one embodiment, the pressure sensor includes at least a first pressure sensor and a second pressure sensor, both electrically connected to the controller and both connected to the airflow channel.

[0013] In one embodiment, the vacuum pump includes a pump body and a silencer. One end of the pump body is connected to the airflow channel, and the other end is connected to one end of the silencer. The other end of the silencer is used to connect to the external space.

[0014] In one embodiment, the vacuum control system further includes a housing and a mounting plate disposed within the housing, wherein a first pad and a second pad are spaced apart on the mounting plate.

[0015] The controller is embedded in the opening of the housing, the valve body and the silencer are mounted on the first pad, and the pump body is mounted on the second pad.

[0016] In one embodiment, the vacuum pump further includes a shock absorber, one end of which is fixedly connected to the mounting plate, and the other end of which is connected to the side of the second pad away from the pump body.

[0017] In one embodiment, a plurality of shock absorbers are provided, and the plurality of shock absorbers are spaced apart between the mounting plate and the second pad.

[0018] This utility model also provides a skin treatment device, which includes an applicator and a vacuum control system. The applicator is used to deliver high-frequency energy and / or drugs to skin tissue. The vacuum control system is a vacuum control system as described above. The vacuum control system is connected to the applicator through the airflow channel and controls the vacuum level of the applicator by detecting the vacuum level of the airflow channel.

[0019] In one embodiment, the vacuum level of the applicator reaches a first preset value, and the applicator delivers the high-frequency energy and / or drug to the skin tissue;

[0020] When the vacuum level of the applicator is less than the second preset value, the vacuum control system issues an alarm.

[0021] The vacuum level of the applicator is reduced to 0, and the applicator is detached from the skin, completing the treatment;

[0022] Wherein, the first preset value is greater than the second preset value.

[0023] This invention proposes a vacuum control system, including a valve body, a vacuum pump, a pressure sensor, and a controller. One end of the valve body is connected to the external space, and the other end is connected to the applicator through an airflow channel. One end of the vacuum pump is connected to the applicator through an airflow channel, and the other end is connected to the external space. When it is necessary to adjust the vacuum level of the skin treatment device, the controller issues a command to start the vacuum pump and valve body, which are electrically connected to it. At this time, the pressure sensor, which is electrically connected to the controller, monitors the vacuum level in the airflow channel in real time and feeds back the monitoring value to the controller. The controller controls the opening of the valve body according to the magnitude of the feedback value to adjust the amount of airflow entering the airflow channel, thereby realizing the adjustment of the vacuum level to meet the vacuum level required by different skin areas.

[0033] Existing skin treatment devices require a vacuum attachment of the applicator to the skin to assist in treatment. Skin treatment includes, but is not limited to, delivering high-frequency energy and / or medications to skin tissue. High-frequency energy includes radiofrequency energy, laser energy, or ultrasound energy with frequencies of 1000Hz and above. Medications include active ingredients and nutrients such as hyaluronic acid, collagen, whitening agents, and botulinum toxin. Because skin treatment devices are frequently used on different skin areas, and these areas have varying requirements for the vacuum attachment intensity of the applicator, existing devices typically have an air inlet valve and a vacuum pump. The vacuum pump extracts air from the inlet valve to achieve a vacuum. Since the opening of the air inlet valve is not adjustable, the vacuum level of the skin treatment device is also not adjustable, making it difficult for the applicator to meet the required vacuum attachment intensity for different skin areas.

[0034] To address the aforementioned issues, this invention proposes a vacuum control system, aiming to resolve the problem that the vacuum degree of existing skin treatment equipment is not adjustable, making it difficult for the applicator of the skin treatment equipment to meet the vacuum adsorption intensity requirements of different skin areas.

[0035] like Figure 1 and Figure 2In one embodiment, the vacuum control system includes a vacuum pump 10, a pressure sensor 20, a valve body 30, and a controller 40. One end of the vacuum pump 10 is connected to an applicator via an airflow channel, and the other end is connected to the external space. The pressure sensor 20 is connected to the airflow channel to detect the vacuum level of the airflow channel. One end of the valve body 30 is connected to the external space, and the other end is connected to the airflow channel. The controller 40 is electrically connected to the valve body 30, the pressure sensor 20, and the vacuum pump 10. The controller 40 controls the opening of the valve body 30 based on the monitoring value of the pressure sensor 20 to control the amount of airflow entering the airflow channel from the outside.

[0036] In this embodiment, the vacuum control system mainly includes a vacuum pump 10, a pressure sensor 20, a valve body 30, and a controller 40. These structures are connected by multiple flexible hoses, and tee ports are installed at specific connection points on the hoses to ensure a complete airflow channel is formed within the vacuum control system. The vacuum pump 10 is connected to one end of the airflow channel to extract air from inside the channel, and the other end, connected to the external space, extracts air into the external environment, thereby creating and maintaining a stable negative pressure environment inside the applicator. The pressure sensor 20 includes at least a first pressure sensor and a second pressure sensor, both connected to the airflow channel and monitoring the vacuum level in the airflow channel in real time. In one embodiment, one of the first and second pressure sensors participates in the pressure detection of the airflow channel, while the other is always in a candidate state. For example, when the first pressure sensor is working, the second pressure sensor is in a candidate state to prevent damage to the first pressure sensor. In another embodiment, both the first and second pressure sensors are working, and their pressure values ​​are processed with various precision methods, such as averaging, to obtain more accurate pressure data within the applicator, ensuring accurate pressure acquisition. The vacuum state inside the applicator provides reliable data support for subsequent control steps. One end of the valve body 30 is connected to the external space, and the other end is connected to the airflow channel. The valve body 30 can adjust its opening according to the control signal to control the amount of external air entering the airflow channel, thereby achieving precise adjustment of the vacuum level. The controller 40 forms a closed-loop control system with the valve body 30, pressure sensor 20, and vacuum pump 10 through electrical connection. Based on the vacuum monitoring value provided by pressure sensor 20, the controller 40 automatically adjusts the opening of the valve body 30 through its own algorithm and processing logic. When the vacuum level inside the applicator is lower than the set value, the controller 40 will instruct the valve body 30 to reduce the opening to restrict the entry of external air, thereby increasing the vacuum level. Conversely, when the vacuum level is too high, the controller 40 will instruct the valve body 30 to increase the opening to allow more external air to enter, thereby reducing the vacuum level and achieving vacuum level adjustment.

[0037] This invention proposes a vacuum control system, including a valve body 30, a vacuum pump 10, a pressure sensor 20, and a controller 40. One end of the valve body 30 is connected to the external space, and the other end is connected to the applicator through an airflow channel. One end of the vacuum pump 10 is connected to the applicator through an airflow channel, and the other end is connected to the external space. When it is necessary to adjust the vacuum level of the skin treatment device, the controller 40 issues a command to start the vacuum pump 10 and the valve body 30, which are electrically connected to it. At this time, the pressure sensor, which is electrically connected to the controller 40, monitors the vacuum level in the airflow channel in real time and feeds back the monitoring value to the controller 40. The controller 40 controls the opening of the valve body 30 according to the magnitude of the feedback value to adjust the amount of airflow entering the airflow channel, thereby realizing the adjustment of the vacuum level to meet the vacuum level required by different skin areas.

[0038] like Figure 1 and Figure 2 In one embodiment, the valve body 30 is a solenoid valve. The valve body 30 has an air inlet with a variable diameter. The valve body 30 controls the size of the air inlet according to its own current to control the amount of airflow entering the airflow channel.

[0039] In this embodiment, the valve body 30 is a solenoid valve. When the solenoid valve receives a current signal from the controller 40, the electromagnetic coil generates a magnetic field. This magnetic field attracts or pushes the valve core, thereby changing the size of the air inlet orifice. If the controller 40 detects a vacuum signal from the pressure sensor 20 indicating that the vacuum inside the applicator is too high, the controller 40 increases the current flowing to the solenoid valve. As the current increases, the attraction of the solenoid valve strengthens, and the valve core is pulled further to the open position, thereby increasing the diameter of the air inlet orifice, allowing more external air to enter the airflow channel and reducing the vacuum level. Conversely, if the vacuum signal detected by the pressure sensor 20 indicates that the vacuum inside the applicator is insufficient, the controller 40 reduces the current flowing to the solenoid valve. The reduction in current weakens the attraction of the solenoid valve, and the valve core moves to the closed position, reducing the diameter of the air inlet orifice, restricting the entry of external air, and thus increasing the vacuum level. Simultaneously, the solenoid valve has a fast response speed and high adjustment precision, enabling the vacuum control system to adapt more flexibly and effectively to different working environments and requirements.

[0040] In other embodiments, the valve body 30 may also be an electric valve, driven by an electric motor, and the flow rate of the valve is controlled by adjusting the speed of the electric motor.

[0041] like Figure 1 and Figure 2 In one embodiment, the vacuum control system includes a filter element 50, which is connected to the end of the valve body 30 that communicates with the external space.

[0042] In this embodiment, the filter element 50 is typically made of a porous material, such as a metal mesh or fiber material. The filter element 50 is connected to the valve body 30 via a threaded connection, ensuring a secure connection while maintaining good sealing to prevent air leakage and thus affecting the vacuum level. The filter element 50 can capture and prevent dust and other particulate matter from passing through, while allowing gas flow. This ensures that the valve body 30 can maintain the required vacuum level while effectively protecting the system from external contaminants, thereby ensuring stable system operation and production efficiency.

[0043] like Figure 1 and Figure 2 In one embodiment, at least one pressure sensor 20 is provided, and at least one pressure sensor 20 is electrically connected to the controller 40 and at least one pressure sensor 20 is connected to the airflow channel.

[0044] In this embodiment, at least one pressure sensor 20 is provided, and the specific number is not limited. When there are multiple pressure sensors 20, they can be arranged side by side or separately upstream and downstream of the airflow channel to facilitate data comparison and verification. By providing multiple pressure sensors 20 in this embodiment, the vacuum control system can achieve redundant monitoring. When one pressure sensor 20 fails, the other pressure sensors 20 can still operate normally, thereby improving the reliability and safety of the system. At the same time, the data provided by multiple pressure sensors 20 can be mutually verified, enabling the controller 40 to more accurately regulate the gas flow.

[0045] like Figure 1 and Figure 2 In one embodiment, the vacuum pump 10 includes a pump body 11 and a silencer 12. One end of the pump body 11 is connected to an airflow channel, and the other end is connected to one end of the silencer 12. The other end of the silencer 12 is used to connect to the external space.

[0046] In this embodiment, the vacuum pump 10 mainly includes a pump body 11 and a silencer 12. One port of the pump body 11 is connected to an airflow channel, allowing the pump body 11 to draw gas from the airflow channel. The other port of the pump body 11 is connected to one end of the silencer 12, so that the noise generated by the pump body 11 when drawing gas can be absorbed or reduced by the silencer 12. The other end of the silencer 12 is open and connected to the external space to facilitate the discharge of gas and noise drawn by the pump. The combination of the pump body 11 and the silencer 12 in this embodiment enables the vacuum pump 10 to not only effectively draw gas but also reduce noise pollution during operation, thereby improving the practicality of the vacuum control system.

[0047] like Figure 1 and Figure 2In one embodiment, the vacuum control system further includes a housing 60, a mounting plate 61 is disposed inside the housing 60, and a first pad 62 and a second pad 63 are mounted on the mounting plate 61 at intervals.

[0048] The controller 40 is embedded in the housing 60, the valve body 30 and the silencer 12 are mounted on the first pad 62, and the pump body 11 is mounted on the second pad 63.

[0049] In this embodiment, the housing 60 is made of metal or a robust plastic material to provide sufficient strength and durability; the mounting plate 61 is located inside the housing 60 and is used to fix and support other components; the first pad 62 and the second pad 63 are spaced apart from the mounting plate 61.

[0050] In this embodiment, the controller 40 is embedded in the housing 60, the valve body 30 and the silencer 12 are installed on the first pad 62, and the pump body 11 is installed on the second pad 63. This design provides suitable positions and spaces for different components to facilitate their disassembly, assembly and maintenance. On the other hand, it isolates the pump body 11 to prevent the vibration generated during its operation from affecting other components, thereby improving the working stability of the vacuum control system.

[0051] like Figure 1 and Figure 2 In one embodiment, the vacuum pump 10 further includes a shock absorber 13, one end of which is fixedly connected to the mounting plate 61, and the other end is connected to the side of the second pad 63 away from the pump body 11.

[0052] In this embodiment, a shock absorber 13 is provided between the mounting plate 61 and the second pad 63. The shock absorber 13 can effectively reduce the vibration of the pump body during operation, protect the pump body and extend its service life, thereby increasing the stability of the entire vacuum pump 10 system and making it more reliable during operation.

[0053] like Figure 1 and Figure 2 In one embodiment, multiple shock absorbers 13 are provided, and the multiple shock absorbers 13 are spaced apart between the mounting plate 61 and the second pad 63.

[0054] In this embodiment, multiple shock absorbers 13 are evenly distributed between the mounting plate 61 and the second pad 63. By absorbing vibration at multiple points, the vibration of the pump body is evenly dispersed, reducing the dependence on a single shock absorber 13 and improving the overall shock absorption effect. At the same time, multi-point support can increase the stability between the pump body and the foundation structure, reducing the movement and tilting of the pump body during operation.

[0055] This utility model also proposes a skin treatment device (not shown), which includes an applicator 70 and a vacuum control system. The applicator 70 is used to deliver high-frequency energy and / or drugs to skin tissue. The vacuum control system is connected to the applicator 70 via an airflow channel and controls the vacuum level of the applicator 70 by detecting the vacuum level of the airflow channel. The specific structure of the vacuum control system is as described in the above embodiments. Since the vacuum control system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0056] like Figure 1 and Figure 2 In a specific embodiment, when the vacuum degree of the applicator 70 reaches a first preset value, the vacuum degree of the applicator 70 is just enough to allow it to adhere to the human skin. At this time, the applicator 70 delivers high-frequency energy and / or drugs to the skin tissue for treatment. When the vacuum degree of the applicator 70 is less than a second preset value, the vacuum degree of the applicator 70 is too low, causing the applicator 70 to be unable to adhere to the human skin. At this time, the vacuum degree control system issues an alarm, and the vacuum degree needs to be readjusted. When the vacuum degree of the applicator 70 is 0, the applicator 70 completes the treatment and detaches from the skin.

[0057] The skin treatment device also includes a water filter 80, which is installed outside the vacuum control system and connected to the airflow channel near the applicator 70 to prevent water-based liquid from leaking out and being sucked into the vacuum airflow system, thus preventing blockage of the airflow.

[0058] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
