Description

Technical Field

[0001] This utility model relates to the field of medical aesthetic device technology, and in particular to a therapeutic device component and a therapeutic device. Background Technology

[0002] Currently, some treatment devices require the treatment head to be placed against the patient's face before treatment. During this process, a fit test is necessary to ensure the treatment effect and the patient's safety.

[0003] Existing adhesion detection methods typically employ photoelectric sensors mounted on the surface of the treatment head. These sensors detect adhesion by receiving light signals. When the treatment head is in contact with the patient's skin, the photoelectric sensor stops receiving light signals, thus indicating that the treatment head has successfully adhered. However, this detection method is susceptible to external environmental influences. If the ambient light intensity is too high, even if the treatment head has adhered properly, the photoelectric sensor may still be affected by the external light, leading to detection errors and affecting the normal operation of the treatment device. Utility Model Content

[0004] The main purpose of this invention is to propose a therapeutic device component that addresses the problem that existing therapeutic devices are easily affected by the external environment during adhesion testing, thus affecting the normal operation of the therapeutic device.

[0005] To address the above problems, this utility model proposes a therapeutic device component, comprising: The housing includes a treatment head housing and a mounting housing connected to each other; A front cover assembly, one end of which is connected to the interior of the treatment head housing; A fixing component, wherein the fixing component is disposed inside the mounting housing, and the fixing component is movably connected to the other end of the front cover assembly, so that it and the front cover assembly can move closer to or further apart from each other; and A detection component, comprising a detection element and a trigger element, wherein either the detection element or the trigger element is mounted on the front cover component, and the other is mounted on the fixing component; the detection element is used to detect and sense the trigger element.

[0007] In one embodiment, the therapeutic device assembly further includes a guide mechanism comprising two guide rods spaced apart along a direction perpendicular to the relative movement of the front cover assembly and the fixing assembly, with each guide rod having its two ends connected to the first mounting plate and the drive mechanism, respectively.

[0008] In one embodiment, the first mounting plate includes a plate body and two guide posts. The two guide posts are connected at a distance to one end of the first mounting plate facing the fixing component. Each of the two guide posts has a guide hole along its own axial direction. The ends of the two guide rods in the same direction are respectively inserted into the two guide holes.

[0009] In one embodiment, the guiding mechanism further includes two first springs, which are respectively sleeved on the two guide rods, and the ends of the two first springs pointing in the same direction abut against and limit the driving mechanism.

[0010] In one embodiment, the guiding mechanism further includes two brackets, which are spaced apart and connected to one end of the driving mechanism facing the front cover assembly. Each bracket has a guide groove, and a limiting groove is formed on one end face of the guide groove.

The fixing assembly is located inside the mounting housing and movably connected to the other end of the front cover assembly, allowing them to move closer or further apart. The detection assembly includes a detection element and a trigger element, either mounted on the front cover assembly or the other on the fixing assembly, thus ensuring the entire detection assembly is located within the housing. When the therapeutic device is applied to the patient's skin with a certain force, the treatment head moves the front cover assembly towards the fixing assembly, causing the detection element and trigger element to move closer until the detection element senses the trigger element. At this point, the detection assembly detects that the therapeutic device is correctly attached to the patient's skin, completing the attachment detection. By embedding the detection assembly inside the therapeutic device, this invention is unaffected by the external environment, thereby improving the detection accuracy of the detection assembly and ensuring the normal operation of the therapeutic device.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without inventive effort are within the protection scope of the present utility model.

[0020] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure).

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] Currently, some therapeutic devices require the treatment head to be placed in close contact with the patient's face before treatment. During this process, contact detection is necessary to ensure treatment effectiveness and safety. Existing contact detection solutions typically use photoelectric sensors mounted on the surface of the treatment head. These sensors detect contact by receiving light signals; when the treatment head is in contact with the patient's skin, the photoelectric sensor stops receiving light signals, thus indicating successful contact. However, this detection method is susceptible to external environmental influences. If the ambient light intensity is too high, even if the treatment head is properly in contact, the photoelectric sensor may still malfunction due to the ambient light, leading to incorrect detection and affecting the normal operation of the therapeutic device.

[0023] To address the aforementioned issues, this invention proposes a therapeutic device component, aiming to resolve the problem that existing therapeutic devices are easily affected by the external environment during adhesion testing, thereby impacting the normal operation of the therapeutic device.

[0024] like Figures 1 to 4 In one embodiment, the treatment device assembly includes a housing (not shown), a front cover assembly 10, a fixing assembly 20, and a detection assembly 30. The housing includes a treatment head housing and a mounting housing connected together. One end of the front cover assembly 10 is connected to the inside of the treatment head housing. The fixing assembly 20 is disposed inside the mounting housing and is movably connected to the other end of the front cover assembly 10 so that it and the front cover assembly 10 can move closer to or further away from each other. The detection assembly 30 includes a detection element 31 and a trigger element 32. Either the detection element 31 or the trigger element 32 is mounted on the front cover assembly 10, and the other is mounted on the fixing assembly 20. The detection element 31 is used to detect the trigger element 32.

[0025] In this embodiment, one end of the front cover assembly 10 is connected to the inside of the treatment head housing to meet the patient's treatment needs. The fixing assembly 20 is movably connected to the other end of the front cover assembly 10. The two can be connected by other means such as slide rails or guide rods 41 to achieve a sliding connection, thereby allowing them to move closer or further apart. The detection assembly 30 includes a detection element 31 and a trigger element 32. In this embodiment, the detection element 31 is installed on the fixing assembly 20, and the trigger element 32 is installed on the end of the front cover assembly 10 near the fixing assembly 20. In other embodiments, the detection element 31 can also be installed on the front cover assembly 10, and the trigger element 32 can be installed on the fixing assembly 20.

[0026] The therapeutic device assembly proposed in this utility model includes a front cover assembly 10, a fixing assembly 20, and a detection assembly 30. One end of the front cover assembly 10 is connected to the inside of the treatment head housing, and the fixing assembly 20 is movably connected to the other end of the front cover assembly 10 so that it and the front cover assembly 10 can move closer or further apart. The detection assembly 30 includes a detection element 31 and a trigger element 32. Either the detection element 31 or the trigger element 32 is installed on the front cover assembly 10, and the other is installed on the fixing assembly 20. When the therapeutic device is applied to the patient's skin with a certain force, the treatment head will drive the front cover assembly 10 to gradually move towards the fixing assembly 20, causing the detection element 31 and the trigger element 32 to move closer together until the detection element 31 detects and senses the trigger element 32. At this time, the detection assembly 30 detects that the therapeutic device is correctly applied to the patient's skin, completing the application detection. Meanwhile, the detection component 30 in this embodiment is built into the treatment device and is not exposed on the surface of the treatment head or outside the component, completely avoiding interference from external light (such as sunlight or shadowless lamps) and completely isolating external environmental interference. At the same time, the detection component 30 uses the detection element 31 and the trigger element 32 to perform contact detection, without relying on external lighting conditions, ensuring that the detection component 30 can be set inside the treatment device and can start and operate normally in various scenarios.

[0027] like Figures 1 to 4 and Figure 6 In one embodiment, the front cover assembly 10 includes a cover body 11 and a first mounting plate 12, and the fixing assembly 20 includes a drive mechanism 21 and a second mounting plate 22. One end of the cover body 11 is used to mount a treatment head. The first mounting plate 12 is detachably connected to the end of the cover body 11 facing the fixing assembly 20, and the second mounting plate 22 is detachably connected to the end of the drive mechanism 21 facing the front cover assembly 10. Either the detection element 31 or the trigger element 32 is mounted on the first mounting plate 12, and the other is mounted on the second mounting plate 22.

[0028] In this embodiment, the front cover assembly 10 includes a cover body 11 and a first mounting plate 12. One end of the cover body 11 is used to mount the treatment head, and the first mounting plate 12 is detachably mounted to the other end of the cover body 11 by means of a threaded connection or snap-fit. Similarly, the trigger element 32 is detachably connected to the first mounting plate 12 by means of a threaded connection or snap-fit. The second mounting plate 22 is mounted to the drive mechanism 21 by means of a threaded connection or snap-fit, and the detection element 31 is detachably connected to the second mounting plate 22 by means of a threaded connection or snap-fit. This embodiment, by adopting a separate design for the cover body 11 and the first mounting plate 12, and the drive mechanism 21 and the second mounting plate 22, makes the maintenance and replacement of the detection element 31 and the trigger element 32 more convenient, without the need to disassemble the entire front cover or the fixing assembly 20. On the other hand, the detachable connection method balances stability and operability, meeting the connection strength requirements of the treatment device while reducing the difficulty of later maintenance, thereby improving the practicality of the treatment device.

[0029] like Figures 1 to 5 In one embodiment, the therapeutic device assembly further includes a guide mechanism 40, which includes two guide rods 41. The two guide rods 41 are spaced apart along the direction of relative movement between the vertical front cover assembly 10 and the fixing assembly 20. Both ends of each guide rod 41 are respectively connected to the first mounting plate 12 and the drive mechanism 21.

[0030] In this embodiment, the guide mechanism 40 is a structure that ensures the relative motion stability between the front cover assembly 10 and the fixed assembly 20. It mainly includes two guide rods 41, which are smooth cylindrical metal rods to ensure high structural strength and reduce friction between themselves and the front cover assembly 10 and the fixed assembly 20, thus improving smoothness of movement. The two guide rods 41 are spaced apart along the direction perpendicular to the relative motion of the front cover assembly 10 and the fixed assembly 20, ensuring uniform distribution of guiding force. One end of each guide rod 41 is inserted into the first mounting plate 12, and the other end is installed in the fixed assembly 20 via a threaded connection or snap-fit, ensuring the installation stability of the guide rod 41 itself. This embodiment, by spaced two guide rods 41 between the front cover assembly 10 and the fixed assembly 20, restricts their relative motion path, effectively preventing lateral displacement of the front cover assembly 10 and the fixed assembly 20 due to external forces, ensuring that the detection element 31 and the trigger element 32 remain aligned, and improving the detection accuracy of the detection element 30.

[0031] like Figures 1 to 4 In one embodiment, the first mounting plate 12 includes a plate body 121 and two guide posts 122. The two guide posts 122 are connected at intervals to one end of the first mounting plate 12 facing the fixing component 20, and one end of two guide rods 41 is respectively inserted into the two guide posts 122.

[0032] In this embodiment, the plate 121 and the two guide posts 122 are integrated into a single design to ensure the structural stability of the first mounting plate 12. The guide posts 122 have axially formed guide holes, which are through holes. The size of the through holes matches the radial dimension of the guide rod 41 to achieve a clearance fit between the guide rod 41 and the through holes. This design of the guide posts 122 further defines the installation position of the guide rod 41, preventing axial displacement of the guide rod 41 due to long-term use or external forces. This improves the movement accuracy between the front cover assembly 10 and the fixing assembly 20, thereby improving the detection accuracy of the detection assembly 30.

[0033] like Figures 1 to 4 In one embodiment, the guide mechanism 40 further includes two first springs 42, which are respectively sleeved on the two guide rods 41, and the concentric ends of the two first springs abut against the drive mechanism 21.

[0034] In this embodiment, the first spring 42 is a buffer reset component of the guide mechanism 40. The first spring 42 is sleeved on the guide rod 41, with one end engaged with the drive mechanism 21 to ensure its installation stability. The first spring 42 allows the front cover assembly 10 and the treatment head to elastically contact the patient's face, ensuring the treatment head always fits tightly against the patient's skin. Simultaneously, when the treatment device is not in operation, the spring is in a naturally straight state. When the treatment head contacts the face and applies pressure, the front cover assembly 10 overcomes the spring's elastic force and moves towards the fixing assembly 20, compressing the spring itself. After treatment, the applied pressure on the treatment head disappears, the elastic potential energy stored in the spring is released, and the linear elastic force pushes the first mounting plate 12 to move in the opposite direction along the guide rod 41, achieving reset. No manual reset is required, improving the operator's efficiency.

[0035] like Figures 1 to 5 In one embodiment, the guide mechanism 40 further includes a second spring 43, and the drive mechanism 21 includes a drive motor 211, a motor mounting plate 212, a motor adapter 213, and an output shaft 214. The motor mounting plate 212 is mounted on one end of the drive motor 211, the motor adapter 213 is mounted on the end of the motor mounting plate 212 away from the drive motor 211, one end of the output shaft 214 is movably connected to the motor adapter 213, and the other end of the output shaft 214 passes through the first mounting plate 12 and abuts against the cover 11. The second spring 43 is sleeved on the output shaft 214 and one end is connected to the motor adapter 213.

[0036] In this embodiment, the drive motor 211 can be a stepper motor. The motor mounting plate 212 and the housing of the drive motor 211 are connected by threads to achieve stable installation, ensuring the installation stability of the drive motor 211. One end of the motor adapter 213 is connected to the output shaft of the drive motor 211 by a threaded or keyed connection and abuts against the motor mounting plate 212. The motor adapter 213 has an oblong hole, and one end of the output shaft 214 has a through hole. The output shaft 214 is inserted into the motor adapter 213 so that the through hole and the oblong hole overlap. Bolts are then passed through the through hole and the oblong hole in sequence so that the inserted part of the output shaft 214 can move relative to the motor adapter 213. When the bolts move to both ends of the oblong hole, it is the relative limit position of the output shaft 214 and the motor adapter 213. The other end of the output shaft 214 is connected to the first mounting plate 12. The second spring 43 is sleeved on the output shaft 214, which plays the role of buffering and resetting as described above by the first spring 42, further improving the working stability of the therapeutic instrument.

[0037] like Figures 4 to 7In one embodiment, the guide mechanism 40 further includes two brackets 44, which are connected to the motor mounting plate 212 at intervals. Each bracket 44 has a guide groove 441. A limit groove 441 is formed on one end face of the guide groove 441. The two ends of the guide rod 41 are respectively inserted into the limit groove 4411 and the drive mechanism 21.

[0038] In this embodiment, the bracket 44 has a U-shaped structure, so that a guide groove 441 is formed in the hollow position of the bracket 44. The bracket 44 includes a frame body along the relative movement direction of the front cover assembly 10 and the rear cover assembly 20 and a plate-shaped structure perpendicular to the relative movement direction of the front cover assembly 10 and the rear cover assembly 20. The frame body and the plate-shaped structure, together with the motor mounting plate 212, form the guide groove 441. A limiting groove 4411 is formed on the groove end face of the guide groove 441 away from the drive mechanism 21. The motor mounting plate 212 of the drive mechanism 21 also has a groove structure at the corresponding position. Specifically, when the guide... One end of rod 41 is inserted into the slot structure of motor mounting plate 212, and the other end is inserted into guide post 122. Bracket 44 gradually moves radially outward from guide rod 41 towards guide rod 41, so that the limiting groove 4411 near drive mechanism 21 abuts against guide rod 41. Then, bracket 44 gradually moves towards motor mounting plate 212 until the end face of guide rod 41 inserted into guide post 122 abuts against the bottom of the limiting groove 4411 away from drive mechanism 21. Simultaneously, bracket 44 is threaded onto motor mounting plate 212, completing the installation of bracket 44. This bracket 44 design further provides support for guide rod 41 and simultaneously achieves dual limiting of guide rod 41 in both axial and radial directions, ensuring that guide rod 41 always remains horizontal, thereby ensuring the relative movement stability of front cover assembly 10 and fixed assembly 20.

[0039] like Figures 1 to 4 and Figure 6 In one embodiment, the first mounting plate 12 has two clearance grooves 123 spaced apart along the direction of relative movement between the vertical front cover assembly 10 and the fixing assembly 20, and one end of a bracket 44 facing away from the motor mounting plate 212 is disposed in one clearance groove 123.

[0040] The first mounting plate 12 has two clearance grooves 123 to prevent the bracket 44 from interfering with the first mounting plate 12 after installation, thereby improving the structural compactness of the treatment device assembly.

[0041] like Figure 1 In one embodiment, the trigger 32 is a photoelectric trigger block and the detection element 31 is an infrared photoelectric sensor.

[0042] In this embodiment, a circuit board 13 is provided on the first mounting plate 12, and the infrared photoelectric sensor is electrically connected to the circuit board 13 to ensure its normal operation. The infrared photoelectric sensor is a slot-type infrared photoelectric sensor, with an infrared emitting tube built into one side of the slot wall and an infrared receiving tube built into the other side of the slot wall. The photoelectric trigger block is a plate-shaped structure. Specifically, when it is not blocked, the receiving tube continuously receives infrared light and outputs a low level; when it is blocked by the trigger block, the receiving tube loses light and outputs a high level, indicating that the trigger 32 has been detected, thereby realizing the switching of the working state of the therapeutic device.

[0043] In another embodiment, the detection element 31 is a Hall sensor and the trigger element 32 is a magnet. Specifically, the treatment head drives the front cover assembly 10 to gradually move towards the fixed assembly 20 until the magnet enters the sensing range of the Hall sensor. The sensor immediately outputs a signal to the control board. If the treatment head does not fully adhere to the patient's skin, the front cover assembly 10 is not displaced enough, the magnet does not enter the sensing range, the sensor has no signal output, and the treatment device is in a locked state, thereby realizing closed-loop control of the treatment device.

[0044] Neither of the above two methods relies on external lighting conditions for testing, ensuring that the detection component 30, located inside the treatment handle, allows the treatment device to start and operate normally in various scenarios.

[0045] This utility model also proposes a therapeutic device (not shown), which includes the therapeutic device components described above. The specific structure of the therapeutic device components is as described in the above embodiments. Since the therapeutic device components adopt all the technical solutions of all the above embodiments, they have at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0046] 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.
