Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically to an ultrasonic therapy component and an ultrasonic therapy instrument. Background Technology

[0002] Focused ultrasound (FUS) is a non-invasive treatment method that is now widely used in the field of skin treatment. It uses focused ultrasound energy output from a transducer to create an action area at a specific depth under the skin, producing one or more biological effects within the action area, thereby achieving the purpose of treating specific skin problems.

[0003] Currently, focused ultrasound treatment heads typically need to be connected to an external coolant system via a flow channel to prevent burns caused by excessive transducer energy when applied to the skin. However, in existing structures, coolant can easily leak from the gaps between the flow channel and the connector during the coolant introduction process, failing to achieve a reliable seal in the flow channel area. This sealing defect not only wastes coolant but can also affect the normal operation of the transducer due to coolant leakage, and even damage internal components of the treatment head. In severe cases, it can reduce the safety and stability of the ultrasound treatment head. Therefore, solving the overall sealing problem of the key flow channel of the treatment head has become an urgent direction for optimization in the design of existing ultrasound treatment heads. Utility Model Content

[0004] This invention provides an ultrasonic therapy component and an ultrasonic therapy device, the purpose of which is to solve the technical problem of poor overall sealing of existing ultrasonic therapy heads.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ultrasound therapy assembly includes an operating handle, a treatment head, a first connecting member, and a second connecting member;

[0007] The operating handle is provided with a piping assembly for connecting to an external coolant source. The piping assembly includes a first pipe and a second pipe.

[0008] The treatment head has a housing assembly and a transducer connected to the operating handle. The housing assembly has a receiving cavity, and the transducer is disposed in the receiving cavity. The wall of the housing assembly is provided with an inlet channel and an outlet channel, and the inlet channel and the outlet channel are both connected to the pipeline assembly and the receiving cavity.

[0009] The first connecting member and the liquid inlet channel are sealed together so that the coolant from the external coolant source enters the interior of the accommodating cavity through the first pipe and the first connecting member.

[0010] The second connecting member and the liquid outlet channel are sealed together so that the coolant in the accommodating cavity flows back to the external coolant source through the second connecting member and the second pipeline.

[0011] In one embodiment, the first connecting member includes a first connector and a second connector, the first connector being sealed to the liquid inlet channel, the second connector being sealed to the liquid outlet end of the first pipeline, and the second connector and the first connector being detachably connected.

[0012] The second connecting member includes a third connector and a fourth connector. The third connector is sealed to the liquid outlet channel, and the fourth connector is sealed to the liquid inlet end of the second pipeline. The fourth connector and the third connector are detachably connected.

[0013] In one embodiment, the outer peripheral wall of the first connector and the inner peripheral wall of the liquid inlet channel are sealed together, or the inner peripheral wall of the first connector and the outer peripheral wall of the liquid inlet channel are sealed together.

[0014] The outer peripheral wall of the third connector is sealed to the inner peripheral wall of the liquid outlet channel, or the inner peripheral wall of the third connector is sealed to the outer peripheral wall of the liquid outlet channel.

[0015] In one embodiment, the first connector is provided with a first valve body. When the first connector is connected to the second connector, the first valve body can be opened by the second connector and is in a connected state. When the first connector and the second connector are separated, the first valve body is in a closed state.

[0016] And / or, the third connector is provided with a second valve body, which, when the third connector is connected to the fourth connector, can be opened by the fourth connector to be in a connected state, and when the third connector is separated from the fourth connector, the second valve body is in a closed state.

[0017] In one embodiment, the second connector is provided with a third valve body. When the first connector is connected to the second connector, the first valve body and the third valve body press against each other so that both the first valve body and the third valve body are in a connected state. When the first connector and the second connector are separated, both the first valve body and the third valve body are in a closed state.

[0018] The fourth connector is provided with a fourth valve body. When the third connector is connected to the fourth connector, the second valve body and the fourth valve body squeeze each other so that the second valve body and the fourth valve body are both in a connected state. When the third connector and the fourth connector are separated, the second valve body and the fourth valve body are both in a closed state.

[0019] In one embodiment, the inner diameter of the liquid outlet channel gradually increases from the liquid inlet of the second connecting member to the accommodating cavity.

[0020] In one embodiment, the operating handle and the housing assembly are detachably connected.

[0021] An ultrasound therapy device includes the aforementioned ultrasound therapy components and a cooling system, the cooling system comprising:

[0022] The coolant supply assembly is connected to the inlet end of the first pipeline and the outlet end of the second pipeline. The coolant supply assembly is capable of supplying coolant to the accommodating cavity and receiving coolant flowing back from the accommodating cavity.

[0023] A refrigeration assembly for cooling the coolant within the coolant supply assembly;

[0024] A control component is used to control the operation of the coolant supply component and the refrigeration component.

[0025] In one embodiment, the cooling assembly includes a compression cooling assembly or a semiconductor cooling assembly;

[0026] The compression refrigeration assembly includes a compressor, a condenser, a heat exchanger, and an air-cooled unit. The compressor, the condenser, the heat exchanger, and the air-cooled unit are connected by connecting pipes to form a cooling circulation loop. The heat exchanger is capable of exchanging heat with the coolant in the coolant supply assembly.

[0027] In one embodiment, a first temperature sensor is provided at one end of the liquid outlet channel that connects to the accommodating cavity. The first temperature sensor is electrically connected to the control component and is used to collect the temperature of the coolant entering the liquid outlet channel and transmit it to the control component so that the control component can control the cooling power of the refrigeration component.

[0028] In one embodiment, a second temperature sensor is provided at the liquid outlet end of the first pipeline. The second temperature sensor is electrically connected to the control component and is used to collect the temperature of the coolant entering the liquid inlet channel and transmit it to the control component so that the control component can control the cooling power of the refrigeration component.

[0029] As can be seen from the above technical solutions, this utility model has the following advantages:

[0030] By incorporating inlet and outlet channels on the housing assembly of the treatment head, and sealing the first and second connecting members to these channels respectively, a tight-fitting structure is formed between the inlet channel and the first connecting member, and between the outlet channel and the second connecting member. This fit directly blocks the leakage path of the coolant during flow within the channels, preventing coolant from seeping out through the gaps between the channels and the connectors, thus sealing the critical channels within the treatment head. Simultaneously, the accommodating cavity provides space for the transducer and, in conjunction with the channel sealing structure, ensures overall sealing, guaranteeing that coolant supplied from an external coolant source can stably enter the accommodating cavity through the sealed channels. This improves the sealing performance of the flow channels in the ultrasonic treatment assembly and effectively solves the sealing problem of the treatment head.

[0031] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model, it can be implemented according to the contents of the specification.

Detailed Implementation

[0040] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0041] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "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 utility model 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 utility model.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] This invention proposes an ultrasonic therapy component.

[0044] See Figure 1As shown, the ultrasound therapy assembly includes an operating handle 1, a treatment head 2, a first connecting member 3, and a second connecting member 4. The operating handle 1 has a piping assembly for connecting to an external coolant source, which consists of a first pipe 5 and a second pipe 6. The treatment head 2 has a housing assembly 21 and a transducer 22. The housing assembly 21 is connected to the operating handle 1, and a receiving cavity 211 is formed inside the housing assembly 21. The transducer 22 is installed inside the receiving cavity 211. The shell assembly 21 has an inlet channel 212 and an outlet channel 213 machined on its wall. The two ends of the inlet channel 212 and the outlet channel 213 are respectively connected to the pipeline assembly and the accommodating cavity 211. One end of the first connecting member 3 is sealed to the inlet channel 212 and the other end is sealed to the first pipeline 5, so that the coolant from the external coolant source can enter the accommodating cavity 211 through the first pipeline 5, the first connecting member 3 and the inlet channel 212 in sequence. One end of the second connecting member 4 is sealed to the outlet channel 213 and the other end is sealed to the second pipeline 6, so that the coolant that has completed heat exchange in the accommodating cavity 211 can flow back to the external coolant source through the outlet channel 213, the second connecting member 4 and the second pipeline 6 in sequence.

[0045] It is understandable that a receiving cavity 211 is provided in the housing assembly 21 of the treatment head 2 and a transducer 22 is installed. During ultrasound treatment, the transducer 22 will generate a large amount of heat. If the heat accumulates, it will burn the skin. On the other hand, long-term overheating will affect the working performance and service life of the transducer 22, and even affect the treatment effect. Therefore, in this embodiment, a pipeline assembly is provided in the operating handle 1 to connect to an external coolant source. The inlet channel 212 and the outlet channel 213, together with the first connecting member 3 and the second connecting member 4, form a complete coolant flow channel. This allows the coolant to flow through the receiving cavity 211 and exchange heat with the transducer 22, thus removing the heat generated by the transducer 22 in a timely manner. At the same time, the sealed connection between the first connecting member 3 and the housing assembly 21, and between the second connecting member 4 and the housing assembly 21, ensures that the coolant will not leak during the flow, thus ensuring the cooling effect and the safety of the equipment.

[0046] When the ultrasound therapy component starts working, the external coolant source is activated and coolant is supplied to the first pipe 5 inside the operating handle 1. The coolant flows through the first pipe 5 to the first connecting member 3. Since the first connecting member 3 is sealed to the inlet channel 212, the coolant enters the inlet channel 212 through the first connecting member 3, and then flows into the receiving cavity 211 inside the treatment head 2 housing assembly 21 from the inlet channel 212. The transducer 22 inside the receiving cavity 211 generates heat during operation. The coolant fully contacts the transducer 22 in the receiving cavity 211 to exchange heat. After absorbing heat, the coolant flows into the outlet channel 213. The outlet channel 213 is sealed to the second pipe 6 through the second connecting member 4. The coolant enters the second pipe 6 through the second connecting member 4 and finally flows back to the external coolant source through the second pipe 6, forming a circulating flow of coolant.

[0047] In one embodiment, the first connecting member 3 is composed of a first connector 31 and a second connector 32. One end of the first connector 31 is sealed to the inlet channel 212 on the housing assembly 21 of the treatment head 2, and one end of the second connector 32 is sealed to the outlet end of the first pipe 5 inside the operating handle 1. The first connector 31 and the second connector 32 are detachably connected. The second connecting member 4 is composed of a third connector 41 and a fourth connector 42. One end of the third connector 41 is sealed to the outlet channel 213 on the housing assembly 21 of the treatment head 2, and one end of the fourth connector 42 is sealed to the inlet end of the second pipe 6 inside the operating handle 1. The third connector 41 and the fourth connector 42 are detachably connected.

[0048] Specifically, both the first connecting member 3 and the second connecting member 4 are designed as detachable two-connector structures, allowing for easy separation and connection between the treatment head 2 and the operating handle 1. During use of the ultrasound therapy assembly, the treatment head 2 may need to be replaced according to the treatment site or treatment requirements. In this case, there is no need to separately disassemble the inlet channel 212 with the first pipe 5, or the outlet channel 213 with the second pipe 6. Instead, the first connector 31 and the second connector 32, and the third connector 41 and the fourth connector 42 can be directly separated. This ensures the sealing of each connection while facilitating disassembly, preventing damage to the seal between the treatment head 2 and the first and second connecting members 3 and 4 during disassembly and installation, thus improving the ease of maintenance and service life of the equipment.

[0049] In one embodiment, the inlet channel 212 is designed as an inner hole structure in the wall of the treatment head 2. In this case, the outer peripheral wall of the first connector 31 and the inner peripheral wall of the inlet channel 212 cooperate to achieve a sealed connection. By fitting the outer peripheral wall of the first connector 31 and the inner peripheral wall of the inlet channel 212 together, the positioning function of the inner hole can be fully utilized to ensure the coaxiality of the connection. Specifically, in this embodiment, the end of the first connector 31 is inserted into the inner hole of the inlet channel 212, and the seal is achieved through the interference fit between the two, so that the coolant can flow smoothly from the first connector 31 into the inlet channel 212 without leakage.

[0050] Furthermore, in this embodiment, the outer periphery of the insertion end of the first connector 31 is machined with several annular sealing grooves, and a sealing ring 311 is installed in each annular sealing groove. The inner hole size of the liquid inlet channel 212 matches the outer diameter of the insertion end of the first connector 31. During assembly, the first connector 31 is inserted into the inner hole of the liquid inlet channel 212. After the sealing ring 311 is compressed, it undergoes elastic deformation and is interference-fitted with the inner peripheral wall of the liquid inlet channel 212 to further improve the sealing performance.

[0051] In another embodiment, the inlet channel 212 is designed as an outwardly protruding tube section (not shown) extending outward from the wall of the treatment head 2. In this case, the inner peripheral wall of the first connector 31 and the outer peripheral wall of the inlet channel 212 cooperate to achieve a sealed connection. Reliable positioning and sealing can also be achieved by fitting the inner peripheral wall of the first connector 31 with the outer peripheral wall of the inlet channel 212. Specifically, in this embodiment, the outwardly protruding tube section of the inlet channel 212 is inserted into the inner hole of the first connector 31, and a seal is achieved through the interference fit between the two, ensuring the sealed flow of coolant and avoiding the risk of leakage.

[0052] Furthermore, in this embodiment, an annular sealing groove is machined on the outer periphery of the protruding pipe section of the liquid inlet channel 212, or an annular sealing groove is machined on the inner peripheral wall of the first connector 31. A sealing ring 311 is installed in each annular sealing groove. The inner hole size of the first connector 31 matches the outer diameter of the protruding pipe section of the liquid inlet channel 212. During assembly, the protruding pipe section is inserted into the inner hole of the first connector 31. The sealing ring 311 is squeezed and undergoes elastic deformation, forming an interference fit with the mating surface to further improve the sealing performance.

[0053] It should be noted that the two mating connection methods between the liquid inlet channel 212 and the first connector 31 can be flexibly selected according to the structural design, processing difficulty and sealing performance requirements of the treatment head 2 housing assembly 21, to ensure the applicability and reliability of the sealing connection.

[0054] It is understood that the connection method between the third connector 41 and the outlet channel 213 is the same as the connection method between the inlet channel 212 and the first connector 31, including two mating connection methods: the outer peripheral wall of the third connector 41 mates with the inner peripheral wall of the outlet channel 213 to achieve a sealed connection, or the inner peripheral wall of the third connector 41 mates with the outer peripheral wall of the outlet channel 213 to achieve a sealed connection. Meanwhile, the sealing connection process between the third connector 41 and the outlet channel 213 is consistent with the connection process between the first connector 31 and the inlet channel 212. Reliable sealing can be achieved by assembling according to the selected connection method. The specific connection structure can be referred to the connection structure between the inlet channel 212 and the first connector 31, and will not be repeated here.

[0055] When the treatment head 2 and the operating handle 1 need to be disassembled, the coolant remaining in the pipeline assembly will leak through the first connecting part 3 and the second connecting part 4, which will not only waste the coolant resources, but may also affect the internal circuit of the equipment and cause damage to the equipment.

[0056] See Figure 1As shown, in one embodiment, a first valve body 33 is installed inside the first connector 31. When the first connector 31 is connected to the second connector 32, the second connector 32 will push the first valve body 33, causing the first valve body 33 to switch from the closed state to the open state, allowing coolant to pass through. When the first connector 31 and the second connector 32 are separated, the first valve body 33 loses the pushing effect of the second connector 32 and automatically returns to the closed state, preventing coolant leakage.

[0057] Specifically, in this embodiment, the first valve body 33 includes a first sliding rod (not shown), a first reset member (not shown), and a first valve core (not shown). The first sliding rod is located inside the first connector 31 near the end of the second connector 32, and the first sliding rod can slide relative to the first connector 31. The first valve core is located at the end of the first sliding rod extending towards the accommodating cavity 211, and is used to block the liquid outlet of the first connector 31. The first reset member can be a reset spring, which is used to reset the first sliding rod. The reset spring, the first sliding rod, and the first valve core are coaxially arranged. The second connector 32 is provided with a first crimping post (not shown). When the second connector 32 is connected to the first connector 31, one end of the first crimping post passes through the liquid inlet of the first connector 31 and presses down the first sliding rod, thereby driving the first valve core to disengage from the liquid outlet of the first connector 31, so that the first connector 31 is in a connected state. At this time, the coolant can flow from the first pipe 5 through the first connecting member 3 into the liquid inlet channel 212. When the second connector 32 separates from the first connector 31, the first crimping post separates from the first sliding rod. The return spring drives the first sliding rod to reset, thereby driving the first valve core to reset and block the liquid outlet of the first connector 31, so that the first connector 31 is in the closed state.

[0058] In another embodiment, a second valve body 43 is installed inside the third connector 41. When the third connector 41 is connected to the fourth connector 42, the fourth connector 42 pushes the second valve body 43, causing the second valve body 43 to switch from a closed state to an open state, allowing coolant to pass through. When the third connector 41 is separated from the fourth connector 42, the second valve body 43 loses the pushing action of the fourth connector 42 and automatically returns to the closed state, preventing coolant leakage.

[0059] Specifically, in this embodiment, the structure of the second valve body 43 is the same as that of the first valve body 33. The second valve body 43 includes a second sliding rod (not shown), a second reset member (not shown), and a second valve core (not shown). The second sliding rod is located inside the third connector 41 near the end of the fourth connector 42. The second sliding rod can slide relative to the third connector 41. The second valve core is located at the end of the second sliding rod extending towards the accommodating cavity 211 and is used to block the liquid outlet of the third connector 41. The second reset member can be a reset spring, which is used to reset the second sliding rod. The reset spring, the second sliding rod, and the second valve core are coaxially arranged. The fourth connector 42 is provided with a second crimping post (not shown). When the fourth connector 42 is connected to the third connector 41, one end of the second crimping post passes through the liquid inlet of the third connector 41 and presses down the second sliding rod, thereby driving the second valve core to disengage from the liquid outlet of the third connector 41, so that the third connector 41 is in a connected state. At this time, the coolant can flow from the second pipe 6 through the second connecting member 4 into the liquid inlet channel 212. When the fourth connector 42 separates from the third connector 41, the second crimping post separates from the second sliding rod. The reset spring drives the second sliding rod to reset, thereby driving the second valve core to reset and block the liquid outlet of the third connector 41, so that the third connector 41 is in the closed state.

[0060] It is understandable that in the above two embodiments, providing a first valve body 33 only on the first connector 31 or a second valve body 43 only on the third connector 41 can reduce the cost and structural complexity of the ultrasound therapy device while meeting basic leak prevention requirements. When the first valve body 33 is provided only on the first connector 31, after disassembling the treatment head 2, the first valve body 33 can prevent the residual coolant in the first pipe 5 from leaking into the receiving cavity 211. However, since the second valve body 43 is not provided on the third connector 41, a small amount of coolant that has not been completely drained from the second pipe 6 may flow back and remain in the receiving cavity 211. However, after disassembling the operating handle 1, the small amount of liquid remaining in the receiving cavity 211 can be drained from the third connector 41. When the second valve body 43 is provided only on the third connector 41, after disassembly, it can prevent the coolant in the receiving cavity 211 from leaking, avoiding it from flowing to the outside of the treatment head 2 and contaminating the treatment environment. The residual liquid in the first pipe 5 is small, and even if a small amount leaks into the receiving cavity 211, it can be easily drained from the first connector 31. This single-sided valve design is suitable for scenarios where leakage control requirements are not high and cost control is more important, such as small home-use ultrasound therapy equipment. In this scenario, it is generally not possible to connect a larger pump structure, and it is impossible to ensure that the coolant in the accommodating cavity 211 is completely drained. The single-sided valve design makes it easier for users to clean the residual liquid in the accommodating cavity 211. At the same time, the single-sided valve design can simplify the manufacturing process, reduce the number of parts, and lower the overall manufacturing cost.

[0061] In another embodiment, a first valve body 33 is installed in the first connector 31 and a second valve body 43 is installed in the third connector 41.

[0062] Specifically, in this embodiment, a first valve body 33 is installed inside the first connector 31. When the first connector 31 and the second connector 32 are connected and communicate through the first valve body 33, the second connector 32 pushes against the first valve body 33, causing the first valve body 33 to switch from a closed state to a connected state, allowing coolant to pass through. When the first connector 31 and the second connector 32 are separated, the first valve body 33 loses the pushing action of the second connector 32 and automatically returns to the closed state, preventing coolant leakage. A second valve body 43 is installed inside the third connector 41. When the third connector 41 and the fourth connector 42 are connected through the second valve body 43, the fourth connector 42 pushes against the second valve body 43, causing the second valve body 43 to switch from a closed state to a connected state, allowing coolant to pass through. Furthermore, when the operating handle 1 is connected to the treatment head 2, the first connector 31 and the third connector 41 are simultaneously in a connected state; when the operating handle 1 is separated from the treatment head 2, the first connector 31 and the third connector 41 are simultaneously in a closed state. It should be noted that this embodiment is a combination of the aforementioned first connector 31 and third connector 41. The specific structure and operation of the first connector 31 and third connector 41 in this embodiment can be referred to the aforementioned related content, and will not be repeated here.

[0063] In this embodiment, a first valve body 33 is provided at the first connector 31 and a second valve body 43 is provided at the third connector 41 to achieve double-sided backflow prevention, maximizing the safety of equipment use and environmental cleanliness. When the treatment head 2 is disassembled from the operating handle 1, the first valve body 33 and the second valve body 43 close to prevent the coolant in the first pipe 5 and the second pipe 6 from flowing out into the receiving cavity 211, ensuring that the treatment head 2 is sealed and no coolant backflow occurs. This effectively protects the internal circuits and mechanical components of the equipment from liquid immersion damage and extends the service life of the equipment. This configuration is suitable for scenarios with extremely high requirements for safety and sealing, such as high-precision medical ultrasound treatment equipment. After the coolant in the receiving cavity 211 is discharged, the operating handle 1 is separated from the treatment head 2. The valve body seals on both flow channels of the treatment head 2 prevent the residual coolant in the first pipe 5 and the second pipe 6 from flowing back into the receiving cavity 211 during the separation process. At the same time, the double-sided seal can effectively prevent liquid ingress or contamination of the treatment head 2 during storage, further improving the reliability of the equipment.

[0064] It is understood that in the above embodiments, the fluid flow is achieved by utilizing the opening effect of the pipeline on the valve body when connected, and the valve body automatically closes to achieve sealing when disconnected. This effectively prevents coolant backflow and leakage during disassembly while not affecting coolant circulation during normal operation, thus improving the convenience and safety of equipment use. It should be noted that the number and arrangement of valve bodies can be flexibly selected according to the actual application scenario and sealing performance requirements, and no further limitations are made here.

[0065] In other embodiments, the first valve body 33 and / or the second valve body 43 may adopt a one-way valve core structure to further prevent coolant backflow and ensure that the coolant circulates only along the flow direction of the external coolant source, the first pipe 5, the inlet channel 212, the accommodating cavity 211, the outlet channel 213, the second pipe 6, and the external coolant source, thereby further ensuring the reliability of the ultrasonic therapy device. It is understood that the one-way valve structure mentioned in this embodiment is a common valve body structure on the market, and the model and specifications can be specifically selected according to the specifications of the treatment head 2; this application does not further limit this.

[0066] See Figures 1 to 4 As shown, in one embodiment, a first valve body 33 is installed on the first connector 31, and a third valve body 34 is installed on the second connector 32. The structures of the first valve body 33 and the third valve body 34 are adapted to each other. When the first connector 31 and the second connector 32 are connected, the ends of the first valve body 33 and the third valve body 34 come into contact with each other and generate a squeezing force, causing them to switch from a closed state to a connected state, forming a connected water flow channel. When the first connector 31 and the second connector 32 are separated, the first valve body 33 and the third valve body 34 return to the closed state under the action of their own reset structure, blocking their respective water flow paths.

[0067] Specifically, in this embodiment, the first valve body 33 is provided with a first valve sleeve 331, a first valve core 332, and a first reset member 333 sequentially from the liquid inlet of the first connector 31 to the liquid outlet of the first connector 31. The first valve sleeve 331, the first reset member 333, and the first valve core 332 are coaxially arranged, and the first valve core 332 and the first reset member 333 are disposed inside the first valve sleeve 331. The liquid outlet of the first valve sleeve 331 is fitted at the liquid inlet position of the first connector 31. The first valve core 332 can slide relative to the inner wall of the first valve sleeve 331. The first reset member 333 can be a reset spring, with one end connected to the first valve core 332 and the other end abutting against the first connector 31. When the first valve body 33 is in the closed state, the elastic restoring force of the return spring in the first valve sleeve 331 causes the first valve core 332 to abut against and block the liquid inlet of the first valve sleeve 331, so that the coolant cannot enter the first valve sleeve 331 from the liquid inlet and flow to the liquid inlet of the first connector 31; when the first valve body 33 is in the connected state, the first valve core 332 is forced to slide towards the first connector 31 to leave the liquid inlet of the first valve sleeve 331, so that the liquid inlet of the first valve sleeve 331 is opened, and the coolant enters the first valve sleeve 331 through the liquid inlet and enters the liquid inlet of the first connector 31.

[0068] The third valve body 34 is located at the outlet of the second connector 32. The third valve body 34 includes a second valve sleeve 341, a second valve core 342, a second reset member 343, and a crimping post 344. The second valve core 342, the second reset member 343, and the crimping post 344 are all located inside the second valve sleeve 341 and are coaxially arranged. The second valve core 342 can slide relative to the inner wall of the second valve sleeve 341 and the outer wall of the crimping post 344. The second reset member 343 can be a reset spring, which is sleeved on the outer wall of the crimping post 344, with one end abutting against the outlet of the second connector 32 and the other end connected to the second valve core 342. When the third valve body 34 is in the closed state, the elastic restoring force of the return spring inside the third valve body 34 causes the second valve core 342 to abut against and block the outlet of the second valve sleeve 341; when the third valve body 34 is in the connected state, the second valve core 342 is forced to slide towards the second connector 32 to leave the outlet of the second valve sleeve 341, thereby opening the outlet of the second valve sleeve 341, and the coolant flows through the inlet of the second connector 32 into the second valve sleeve 341 and through the outlet of the second valve sleeve 341 into the first connector 31.

[0069] When the first connector 31 and the second connector 32 are connected, the first valve sleeve 331 is inserted into the second valve sleeve 341. The first valve sleeve 331 presses the second valve core 342 to slide towards the second connector 32. At the same time, the pressing post 344 presses the first valve core 332 to slide towards the first connector 31. At this time, the liquid outlet of the second valve sleeve 341 is connected to the liquid inlet of the first valve sleeve 331, and the first connector 31 and the second connector 32 are connected.

[0070] Furthermore, in this embodiment, a second valve body 43 is installed on the third connector 41, and a fourth valve body 44 is installed on the fourth connector 42. The structures of the second valve body 43 and the fourth valve body 44 are compatible. When the third connector 41 and the fourth connector 42 are connected, the ends of the second valve body 43 and the fourth valve body 44 come into contact with each other and generate a squeezing force, causing them to switch from a closed state to a connected state, forming a connected water flow channel. When the third connector 41 and the fourth connector 42 are separated, the second valve body 43 and the fourth valve body 44 return to the closed state under the action of their own reset structure, blocking their respective water flow paths. It should be noted that in this embodiment, the third connector 41 has the same structure as the first connector 31, and the second valve body 43 has the same structure as the first valve body 33; the fourth connector 42 has the same structure as the second connector 32, and the fourth valve body 44 has the same structure as the third valve body 34. However, the inlet and outlet directions of the second valve body 43 are opposite to those of the first valve body 33, and the inlet and outlet directions of the fourth valve body 44 are opposite to those of the third valve body. The specific structures of the second valve body 43 and the fourth valve body 44 can be referred to the above description of the first valve body 33 and the third valve body 34, and will not be repeated here.

[0071] It is understandable that when the first connector 31 is separated from the second connector 32, and the third connector 41 is separated from the fourth connector 42, relying solely on a single valve body may pose a risk of insufficient sealing reliability. In this embodiment, by setting valve bodies in the two connectors that are connected, the valves can be opened synchronously by mutual compression during connection and closed independently when separated, forming a double sealing structure. This further enhances the anti-leakage effect and avoids leakage problems caused by the failure of a single valve body. It ensures that when the treatment head 2 is disassembled, the ports of the first pipeline 5, the inlet channel, the outlet channel, and the second pipeline 6 are all in a sealed state, improving the safety and reliability of the equipment.

[0072] See Figure 1 As shown, in one embodiment, the liquid outlet channel 213 of the wall of the treatment head 2 housing assembly 21 adopts a variable diameter structure, and its inner diameter gradually increases from the end near the liquid inlet of the second connecting member 4 to the end near the accommodating cavity 211, that is, the inner diameter of the end of the liquid outlet channel 213 near the accommodating cavity 211 is greater than the inner diameter of the end near the second connecting member 4.

[0073] Specifically, by designing the outlet flow channel 213 with a gradually increasing inner diameter, the flow velocity of the coolant flowing from the accommodating cavity 211 into the outlet flow channel 213 can be reduced, thereby reducing flow resistance and pressure loss, avoiding the generation of eddies at the inlet of the outlet flow channel 213, and allowing the coolant in the accommodating cavity 211 to flow more smoothly into the outlet flow channel 213, thus improving the circulation speed and heat exchange efficiency of the coolant.

[0074] In another embodiment, the inlet edge of the outlet channel 213 is connected by a rounded transition (not shown), so that the coolant in the accommodating cavity 211 can flow more smoothly into the outlet channel 213.

[0075] In another embodiment, the liquid outlet channel 213 adopts a stepped variable diameter structure (not shown). Two orifice sections with different inner diameters are arranged sequentially from the accommodating cavity 211 to the second connecting member 4. The orifice section closer to the accommodating cavity 211 has a larger inner diameter, and the orifice section closer to the second connecting member 4 has a smaller inner diameter. The two orifice sections are connected by a circular arc transition. The difference in inner diameter of the orifice sections is determined according to the coolant flow rate requirements to ensure that the liquid flow can be smoothly transitioned.

[0076] In one embodiment, the operating handle 1 and the housing assembly 21 of the treatment head 2 are detachably connected. This detachable connection structure enables the fixing and separation of the two, while ensuring the structural stability after connection.

[0077] Understandably, different treatment scenarios require different specifications or types of treatment heads 2. For example, treatment of different body parts may require treatment heads 2 of different shapes, and treatment depths may require transducers 22 of different power. Designing the operating handle 1 and the housing assembly 21 as detachable connections facilitates quick replacement of the treatment head 2 according to actual needs, without having to replace the entire ultrasound treatment assembly, thus reducing usage costs. When the treatment head 2 malfunctions, it can also be disassembled separately for repair or replacement, improving maintenance convenience.

[0078] Furthermore, when the treatment head 2 needs to be installed, align the connecting structure on the housing assembly 21 of the treatment head 2 with the connecting structure on the operating handle 1, and fix the two together by rotating, inserting, or snapping to complete the detachable connection assembly. At this time, the pipeline assembly and the inlet channel 212 and outlet channel 213 are sealed and connected through the first connecting member 3 and the second connecting member 4. When the treatment head 2 needs to be replaced or maintained, follow the reverse operation steps of the assembly to release the detachable connection between the operating handle 1 and the housing assembly 21, so that the treatment head 2 can be separated from the operating handle 1, a new treatment head 2 can be replaced, or the disassembled treatment head 2 can be maintained. After maintenance, it can be reassembled.

[0079] In this embodiment, a snap-fit ​​connection can be used to achieve a detachable connection between the operating handle 1 and the treatment head 2. The inner peripheral wall of the operating handle 1 near the treatment head 2 has a snap-fit ​​groove, and the outer peripheral wall of the treatment head 2 near the operating handle 1 has a snap-fit ​​component, which snaps into the snap-fit ​​groove. It should be noted that this embodiment only illustrates a preferred connection method. In practical applications, the detachable structure of the operating handle 1 and the housing assembly 21 can be flexibly designed and selected according to requirements, including but not limited to the connection method used in this embodiment.

[0080] See Figures 1 to 5 As shown, this utility model also proposes an ultrasonic therapy device, which includes an ultrasonic therapy component. The specific structure of the ultrasonic therapy component is as described in the above embodiments. Since this ultrasonic therapy device 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.

[0081] Further, see Figure 5 As shown, in one embodiment, the ultrasound therapy device further includes a cooling system 7, which consists of a coolant supply component 71, a cooling component 72, and a control component (not shown). The output end of the coolant supply component 71 is connected to the inlet end of the first pipe 5 in the ultrasound therapy component, and the input end of the coolant supply component 71 is connected to the outlet end of the second pipe 6. The coolant supply component 71 can deliver coolant to the receiving cavity 211 and simultaneously receive coolant flowing back from the receiving cavity 211. The cooling component 72 is connected to the coolant supply component 71 and is used to cool and reduce the temperature of the coolant stored or flowing in the coolant supply component 71, so that the coolant is maintained within a set temperature range. The control component is used to control the operation of the coolant supply component 71 and the cooling component 72.

[0082] Understandably, when the ultrasound therapy component is working, a continuous and stable low-temperature coolant is required to cool the transducer 22. Relying solely on an external natural cooling source cannot guarantee the stability of the coolant temperature. After multiple circulations, the coolant temperature will rise, and the cooling effect will decrease. In this embodiment, a cooling system 7 is provided, with the coolant supply component 71 providing stable coolant circulation power to ensure a continuous flow of coolant through the accommodating cavity 211. Simultaneously, the cooling component 72 cools the returning coolant in real time, ensuring that the coolant temperature always meets the cooling requirements of the transducer 22, guaranteeing stable transducer 22 performance, and improving the effectiveness and safety of ultrasound therapy. The control component is electrically connected to the coolant supply component 71 and the cooling component 72. It can receive detection signals from different sensors in the coolant supply component 71 and the cooling component 72, and send control signals to the coolant supply component 71 and the cooling component 72 according to a preset program or operator instructions to adjust the coolant circulation flow rate, pressure, and cooling power of the cooling component 72.

[0083] Furthermore, the coolant supply assembly 71 includes a reservoir 711 and a circulation pump 712. The reservoir 711 is used to store coolant, and the circulation pump 712 is installed on the output pipeline of the reservoir 711, with its output end connected to the inlet end of the first pipeline 5. The refrigeration assembly 72 is connected to the reservoir 711 through a connecting pipeline. After the circulation pump 712 is started, it pumps the coolant in the reservoir 711 into the first pipeline 5, and the coolant returning from the second pipeline 6 flows into the reservoir 711. The refrigeration assembly 72 cools the coolant in the reservoir 711.

[0084] Further, see Figure 5 As shown, in one embodiment, the refrigeration assembly 72 is a compression refrigeration assembly, which consists of a compressor 721, a condenser 722, a heat exchanger 723, and an air-cooled unit 724. The compressor 721, condenser 722, heat exchanger 723, and air-cooled unit 724 are connected sequentially through connecting pipes to form a closed cooling loop. The heat exchanger 723, as the refrigeration end, directly or indirectly contacts the coolant in the coolant supply assembly 71 to achieve heat exchange. It can be understood that the compression refrigeration assembly achieves refrigeration through the phase change of the refrigerant, and has the characteristics of large refrigeration capacity and high refrigeration efficiency, making it suitable for scenarios requiring continuous high-intensity refrigeration. Specifically, compressor 721 compresses the refrigerant into a high-temperature, high-pressure gas and sends it into condenser 722. Air-cooled unit 724 starts to blow air into condenser 722 to dissipate heat. The refrigerant condenses into a high-pressure liquid in condenser 722 and then flows into heat exchanger 723. In heat exchanger 723, the refrigerant evaporates and absorbs heat, thereby cooling the coolant in coolant supply component 71. The evaporated refrigerant returns to compressor 721, completing the refrigeration cycle.

[0085] In another embodiment, the cooling component is a semiconductor cooling component (not shown). Cooling is achieved through a semiconductor thermoelectric generator, with its cooling end in contact with the coolant supply component 71 for heat exchange. It is understood that semiconductor cooling components are simple in structure, small in size, have no moving mechanical parts, and low in noise, making them suitable for scenarios with high requirements for size and noise reduction. Specifically, one end of the semiconductor thermoelectric generator forms the cooling end, and the other end forms the heating end. The cooling end is in contact with the heat exchange component of the coolant supply component, absorbing heat from the coolant through heat conduction. The heating end is equipped with a heat sink and a cooling fan for heat dissipation, thereby cooling the coolant.

[0086] It is understandable that different usage scenarios have different requirements for cooling capacity and equipment size, and therefore different cooling methods. For example, compression cooling components are more suitable for large ultrasound therapy equipment, while semiconductor cooling components are more suitable for small home-use ultrasound therapy equipment. However, it should be noted that the two cooling methods mentioned in the above embodiments are only illustrative examples. In practical applications, the cooling methods of the ultrasound therapy device of this utility model include, but are not limited to, the two cooling methods mentioned in the above embodiments, in order to improve the applicability of the device.

[0087] See Figures 1 to 5 As shown, in one embodiment, a first temperature sensor 8 is installed at the end of the liquid outlet channel 213 of the treatment head 2 housing assembly 21 that communicates with the accommodating cavity 211. The detection end of the first temperature sensor 8 extends into the liquid outlet channel 213 or is close to the inner wall of the liquid outlet channel 213, and is used to detect the temperature of the coolant flowing out of the accommodating cavity 211 and into the liquid outlet channel 213 in real time. The first temperature sensor 8 is electrically connected to the control component of the ultrasonic therapy instrument and transmits the detected temperature signal to the control component.

[0088] Specifically, the coolant temperature at the end of the outlet channel 213 near the receiving cavity 211 directly reflects the heat dissipation and cooling effect of the transducer 22. If the temperature is too high, it indicates that the heat generated by the transducer 22 has not been sufficiently dissipated, which may affect the performance of the transducer 22. By setting a first temperature sensor 8 at this location, the actual operating temperature environment of the transducer 22 can be monitored in real time, and the control component can adjust the working state of the cooling component 72 according to the detected temperature signal. When the temperature is higher than the set threshold, the cooling power of the cooling component 72 is increased or the coolant circulation flow rate is increased; when the temperature is lower than the set threshold, the cooling power is reduced or the flow rate is decreased, realizing intelligent adjustment of the cooling component 72, ensuring stable cooling effect, and avoiding energy waste.

[0089] Furthermore, a second temperature sensor is installed near the outlet end of the first pipe 5 of the ultrasonic therapy component. That is, the second temperature sensor is located near the end of the first pipe 5 connected to the first connecting member 3. The detection end of the second temperature sensor is in contact with the coolant in the first pipe 5 to detect the temperature of the coolant about to enter the inlet channel 212 in real time. The second temperature sensor is electrically connected to the control component and transmits the detected temperature signal to the control component.

[0090] It is understandable that if the temperature of the coolant flowing into the inlet channel 212 is too high, even if the coolant undergoes sufficient heat exchange within the accommodating cavity 211, it will not effectively reduce the temperature of the transducer 22. Specifically, in this embodiment, by setting a second temperature sensor at the outlet end of the first pipe 5, the initial temperature of the coolant entering the accommodating cavity 211 can be monitored in real time. Combined with the outlet temperature detected by the first temperature sensor 8, the heat generation of the transducer 22 and the heat exchange efficiency of the cooling component 72 can be calculated. The control component adjusts the working state of the cooling component 72 according to the inlet temperature to ensure that the temperature of the coolant entering the accommodating cavity 211 is always at the optimal cooling temperature. At the same time, the temperature difference between the inlet and outlet can be used to determine whether the cooling component 72 is working properly, thereby improving the fault diagnosis capability of the ultrasound therapy device.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the 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 or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
