Description

Technical Field

[0001] This application belongs to the field of ultrasound therapy technology, and more specifically, relates to an ultrasound therapy device and its cooling system. Background Technology

[0002] Ultrasound is a high-frequency mechanical wave with focusable properties, tissue penetration, and energy deposition. Ultrasound therapy equipment utilizes a focused ultrasound transducer to focus ultrasound waves onto a living organism. The interaction between the ultrasound waves and biological tissue generates thermal, cavitation, and mechanical effects, thus exerting corresponding biological effects. Ultrasound therapy equipment consists of a main unit and a handpiece. The transducer in the handpiece emits ultrasound waves to act on the skin.

[0003] The utility model patent with application number CN201520088495.8 discloses a focused ultrasound beauty device, which has a motor inside the handpiece. Under the control of the motor, the precise distribution of focused energy points of the focused piezoelectric ceramic sheet on the skin surface can be precisely controlled.

[0004] However, the motor inside the handpiece generates a lot of heat when it is working, causing the handpiece's temperature to rise rapidly in a short period of time. This can easily burn the operator and cause malfunctions in the electrical components inside the handpiece. Utility Model Content

[0005] This application provides an ultrasound therapy device and its cooling system to solve the technical problem of the handpiece of the ultrasound therapy device easily overheating in the prior art.

[0006] Therefore, according to one aspect of this application, a cooling system for an ultrasound therapy device is provided, the ultrasound therapy device including a main unit and a handpiece, the handpiece having a transducer assembly and a motor for driving the transducer assembly, the cooling system comprising:

[0007] The air pump is located inside the main unit;

[0008] The air intake pipe connects to the air pump's air inlet at one end and to the outside of the main unit at the other end; and

[0009] The air outlet pipe is connected at one end to the air outlet of the air pump, and at the other end to the inside of the hand tool.

[0010] Optionally, the cooling system also includes a finned radiator, which is attached to the outer surface of the motor, with the outlet of the exhaust pipe pointing towards the finned radiator.

[0011] Alternatively, the exhaust pipe is fixed to the finned heat sink.

[0012] Alternatively, the exhaust pipe is attached to the finned heatsink.

[0013] Optionally, both the intake and exhaust pipes can be made of polyurethane.

[0014] Optionally, a protective sleeve connects the main unit and the handpiece, with the air outlet pipe inserted inside the protective sleeve.

[0015] Optionally, the cooling system also includes a threaded straight connector, which is screwed onto the housing of the main unit, and the intake pipe is fitted onto the threaded straight connector.

[0016] Optionally, the cooling system may also include a bladder filter disposed on the intake manifold.

[0017] Optionally, the main unit is equipped with a mounting plate, and the air pump is fixed to the mounting plate by a bolt and nut structure. The bolt and nut structure is equipped with a shock-absorbing pad, and the pad is squeezed and clamped between the air pump and the mounting plate.

[0018] The beneficial effects of the cooling system provided in this application are as follows:

[0019] On the one hand, compared with the prior art, the cooling system of this application is applied to an ultrasound therapy device. The cooling system includes an air pump, an air inlet pipe and an air outlet pipe. Cold air from the outside enters the inside of the handpiece in sequence through the air inlet pipe, the air pump and the air outlet pipe, thereby reducing the temperature of the handpiece, improving the operator's grip experience and reducing the failure rate of electrical components inside the handpiece.

[0020] On the other hand, compared with cooling systems that use liquid cooling media, the cooling system of this application uses gas cooling media, so there is no problem of liquid cooling media leakage, and the electrical components inside the hand will not be short-circuited due to liquid cooling media leakage, thus ensuring high safety performance.

[0021] On the other hand, the air pump of the cooling system of this application is located inside the main unit of the ultrasound therapy device, with only the end of the air outlet pipe extending into the handpiece. Therefore, it does not occupy too much space in the handpiece, allowing the handpiece to still maintain a small size.

[0022] According to another aspect of this application, an ultrasound therapy device is provided, which includes a main unit and a handpiece, the handpiece having a transducer assembly and a motor for driving the transducer assembly, and the ultrasound therapy device also includes a cooling system as described above.

[0032] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0034] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] According to one aspect of this application, please refer to the following: Figures 1 to 3 The embodiments of this application provide a cooling system for an ultrasound therapy device 1000, which includes a main unit 100 and a handpiece 200. The handpiece 200 has a transducer assembly 220 and a motor 210 for driving the transducer assembly 220. The cooling system includes an air pump 1, an air inlet pipe 2, and an air outlet pipe 3. The air pump 1 is disposed inside the main unit 100. One end of the air inlet pipe 2 is connected to the air inlet of the air pump 1, and the other end of the air inlet pipe 2 is connected to the outside of the main unit 100. One end of the air outlet pipe 3 is connected to the air outlet of the air pump 1, and the other end of the air outlet pipe 3 is connected to the inside of the handpiece 200.

[0037] Understandably, the handpiece 200 typically consists of a handle and a treatment head. A transducer assembly 220 is housed within the treatment head, and a motor 210 is housed within the handle. The motor 210 drives the transducer assembly 220 to move linearly or rotate. The treatment head is mounted at the head of the handle, and the motor 210 is located at the tail of the handle. The air outlet 3 is inserted into the handle from the tail. Outside cold air exchanges heat with the handle, becoming hot air. This hot air then flows out through the gap between the handle and the treatment head, and / or the gap in the handle's housing, thus carrying away heat from the handpiece 200 and achieving a cooling effect.

[0038] On the one hand, compared with the prior art, the cooling system of this application is applied to the ultrasound therapy device 1000. The cooling system includes an air pump 1, an air inlet pipe 2 and an air outlet pipe 3. Cold air from the outside enters the inside of the handpiece 200 through the air inlet pipe 2, the air pump 1 and the air outlet pipe 3 in sequence, thereby reducing the temperature of the handpiece 200, improving the operator's grip experience and reducing the failure rate of electrical components (such as motor 210, transducer assembly 220, circuit board, etc.) inside the handpiece 200.

[0039] On the other hand, compared with cooling systems that use liquid cooling media, the cooling system of this application uses gas cooling media, so there is no problem of liquid cooling media leakage, and the electrical components inside the handpiece 200 will not be short-circuited due to liquid cooling media leakage, thus ensuring high safety performance.

[0040] On the other hand, the air pump 1 of the cooling system of this application is located inside the main unit 100 of the ultrasound therapy device 1000, and only the end of the air outlet pipe 3 extends into the handpiece 200. Therefore, it will not occupy too much space in the handpiece 200, so that the handpiece 200 can still maintain a small size.

[0041] In one embodiment, see Figure 3 The cooling system also includes a finned radiator 4, which is attached to the outer surface of the motor 210, and the port of the exhaust pipe 3 points to the finned radiator 4.

[0042] Specifically, the finned heat sink 4 significantly increases the surface area through densely arranged thin metal fins, thereby improving heat dissipation efficiency. This design utilizes both air convection and thermal radiation mechanisms to accelerate heat dissipation. In particular, the port of the exhaust pipe 3 in this application points to the fins of the finned heat sink 4, thereby improving the convective heat dissipation effect of the finned heat sink 4 and accelerating the cooling speed of the motor 210.

[0043] Optionally, this embodiment provides various fixing methods for the finned heat sink 4 and the motor 210. For example, the finned heat sink 4 can be directly attached to the surface of the motor 210 with high-temperature adhesive; or, the motor 210 can be provided with threaded holes, and the heat sink fins can be fastened to the motor 210 with screws.

[0044] In one specific embodiment, please refer to Figure 3 The exhaust pipe 3 is fixed on the finned heat sink 4, which reduces the distance between the exhaust port of the exhaust pipe 3 and the finned heat sink 4, further improving the convection heat dissipation effect of the finned heat sink 4.

[0045] Optionally, this embodiment provides multiple fixing methods for the exhaust pipe 3 and the finned radiator 4. For example, the exhaust pipe 3 can be fixed by binding it to the finned radiator 4 with straps; or, a sleeve can be installed on the finned radiator 4, and the exhaust pipe 3 can be pressed into the sleeve for fixing; or, adjustable-pitch clamps can be installed on the finned radiator 4 with screws, and the exhaust pipe 3 can be fixed to the finned radiator 4 by the clamps.

[0046] Optionally, when the exhaust pipe 3 is tied to the finned radiator 4 with a strap, the strap can be a cotton strap, nylon strap, plastic strap or rubber strap, etc., and is not limited to one type.

[0047] Preferably, please refer to Figure 3 The exhaust pipe 3 is tied to the finned heat sink 4 by a self-locking cable tie 5. The self-locking cable tie 5 is a mature product on the market, with low cost and economic benefits. Its head is designed with ratchet teeth and buckles, tightening in one direction and unable to loosen in the opposite direction. This design ensures that it will not easily loosen when subjected to vibration or tension, and has high reliability.

[0048] Understandably, please refer to Figure 3 Since the finned heat sink 4 is fixedly attached to the surface of the motor 210, when binding the exhaust pipe 3, in order to facilitate the wrapping of the self-locking cable tie 5, the motor 210, the finned heat sink 4 and the exhaust pipe 3 are bound together.

[0049] In some embodiments, both the air inlet pipe 2 and the air outlet pipe 3 are made of polyurethane.

[0050] Specifically, PU hoses are industrial hoses made of polyurethane (PU) material. Positioned as multi-functional pipeline products, they are mainly used in compressed air transportation, liquid transmission, and powder and granular material handling. They have advantages such as chemical corrosion resistance, light weight, and high wear resistance.

[0051] In other embodiments, please refer to [the relevant documentation]. Figures 1 to 3 A protective sleeve 6 connects the main unit 100 and the hand tool 200, and the air outlet pipe 3 is inserted into the protective sleeve 6 to prevent the air outlet pipe 3 from being worn.

[0052] Understandably, the main unit 100 contains a power supply and controller, and the electrical components (such as motor 210, transducer assembly 220, circuit board, etc.) in the handpiece 200 are connected to the power supply and / or controller by wires. These wires are also inserted into the protective sleeve 6 to prevent the wires from being worn.

[0053] Further, please refer to Figure 3 A sealing plug 230 is provided at the connection between the protective sleeve 6 and the hand tool 200. The sealing plug 230 has a through hole, and the wall surface of the through hole is sealed to the outer surface of the protective sleeve 6. The outer peripheral surface of the sealing plug 230 is sealed to the opening edge of the hand tool 200, thereby sealing the connection gap between the protective sleeve 6 and the hand tool 200. The sealing plug 230 has both elasticity and a certain thickness, which can prevent the protective sleeve 6 from bending and deforming, and also prevent the connection between the protective sleeve 6 and the hand tool 200 from being worn.

[0054] In other embodiments, please refer to [the relevant documentation]. Figure 1 and Figure 2 The cooling system also includes a threaded straight connector 7, which is screwed onto the housing of the main unit 100, and the intake pipe 2 is sleeved on the threaded straight connector 7.

[0055] Preferably, the threaded straight connector 7 is a tracheal PC (Physical Contact) connector, with the external thread end of the tracheal PC connector screwed into the threaded hole of the outer shell, and the other end of the tracheal PC connector allowing for quick insertion of the air inlet pipe 2.

[0056] In other embodiments, please refer to Figure 2 The cooling system also includes a bladder filter 8 installed on the intake pipe 2.

[0057] The capsule filter 8 is an integrated filtration device that uses a pleated filter membrane design to increase the filtration surface area. It is suitable for filtering large volumes of solutions and gases in laboratory and industrial applications. The air inlet pipe 2 filters dust from the outside air through the capsule filter 8, preventing dust from accumulating inside the handpiece 200.

[0058] Furthermore, in order to reduce noise, a capsule filter 8 with a noise reduction function can be used, which has both noise reduction and filtration functions.

[0059] In other embodiments, please refer to Figure 2 The main unit 100 is equipped with a mounting plate 110. The air pump 1 is fixed to the mounting plate 110 by a bolt and nut structure 9. The bolt and nut structure 9 is equipped with a shock-absorbing pad 10. The pad 10 is squeezed and clamped between the air pump 1 and the mounting plate 110.

[0060] Thus, the mounting plate 110 inside the main unit 100 provides a mounting position for the air pump 1. The air pump 1 does not need to be installed on the outer casing of the main unit 100. That is, the bolt and nut structure 9 is completely hidden inside the main unit 100 and does not need to penetrate the outer casing of the main unit 100, which improves the aesthetics of the main unit 100. The gasket 10 can play a role in shock absorption and cushioning, reducing the noise of the air pump 1 during operation.

[0061] According to another aspect of this application, please refer to [the relevant document / reference]. Figures 1 to 3 Embodiments of this application also provide an ultrasound therapy device 1000, which includes a main unit 100 and a handpiece 200. The handpiece 200 has a transducer assembly 220 and a motor 210 for driving the transducer assembly 220. The ultrasound therapy device 1000 also includes the cooling system described above. Therefore, the ultrasound therapy device 1000 also has the advantages and benefits brought by the cooling system described above, which will not be repeated here.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
