Description

Technical Field

[0001] This invention belongs to the field of cryogenic weight loss technology, and particularly relates to a split-type cryogenic handle and cryogenic device. Background Technology

[0002] With the continuous improvement of people's living standards and changes in lifestyle and work patterns, obesity has become a new social problem. Obesity refers to a certain degree of significant overweight and excessive fat layer. Fat easily accumulates in areas such as the abdomen, buttocks, thighs, waist, back, and upper arms, affecting both physical health and appearance.

[0003] There are many methods for weight loss, such as medication, exercise, and diet. Recently emerging methods include cryolipolysis, which utilizes the property that triglycerides in fat solidify at 5°C. A non-invasive device delivers freezing waves to the desired area, converting the triglycerides into solids. These solidified triglycerides age prematurely and are then gently eliminated and excreted through normal metabolism, gradually reducing the fat layer and achieving localized weight loss.

[0004] However, existing cryolipolysis devices use a handle to freeze specific areas of the body. Since fat accumulation occurs in different locations, the shape of the handle's working end also varies. Since existing handles are all one-piece structures, the shape of the working end cannot be changed. Consequently, different handles are required to freeze different areas, increasing costs and reducing work efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a split-type freezer handle to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides a split-type freezing handle, comprising a freezing cup and a handle body. The freezing cup is provided with a negative pressure chamber with an opening on one side. A semiconductor cooler is disposed on the side of the freezing cup opposite to the opening. The cooling end of the semiconductor cooler is in contact with the freezing cup, and the heating end of the semiconductor cooler is in contact with a liquid cooling element. The handle body is provided with a cooling pipe and a negative pressure pipe. The negative pressure chamber and the negative pressure pipe, as well as the liquid cooling element and the cooling pipe, are detachably connected and interconnected. A connecting rod is rotatably connected to the handle body, and the side of the connecting rod near the freezing cup is detachably connected to the freezing cup.

[0009] Optionally, the liquid cooling element is a liquid cooling box, one side of which is in contact with the heating end of the semiconductor cooler. The side of the cooling box away from the heating end is provided with two sets of first pipes, and the cooling pipes are provided with two sets of second pipes that are arranged opposite to the two sets of first pipes. The opposite first pipes and second pipes are detachably connected and connected.

[0010] Optionally, an anti-overflow assembly is provided between the first pipeline and the second pipeline, which are arranged opposite to each other. The anti-overflow assembly includes a spring and a first anti-overflow element. The first anti-overflow element is slidably disposed in the first pipeline, and the spring is disposed between the first anti-overflow element and the liquid cooling tank. Under the elastic force of the spring, the first anti-overflow element blocks the outer port of the first pipeline. The first pipeline and the second pipeline are engaged. Under the squeezing action of the second pipeline, the first anti-overflow element overcomes the elastic force of the spring and moves away from the outer port of the first pipeline. The first pipeline and the second pipeline are in a conductive state.

[0011] Optionally, the first anti-overflow element is a blind tube with its open end located on the side near the outer port of the first pipeline, and the closed end of the first anti-overflow element abuts against the spring; a first conductive port is provided on the side wall of the first anti-overflow element near the closed end, and the first conductive port is connected to the inner cavity of the first anti-overflow element; when the first anti-overflow element blocks the outer port of the first pipeline under the elastic force of the spring, the first conductive port abuts against the inner wall of the first pipeline; when the first pipeline and the second pipeline are in a conductive state, the first conductive port is connected to the inside of the liquid cooling box.

[0012] Optionally, a second anti-overflow element is slidably disposed inside the second pipeline. The second anti-overflow element is a blind pipe with its open end located near the external port of the second pipeline, and its closed end located inside the second pipeline. A second through-hole is provided on the side wall of the second anti-overflow element, and the second through-hole is connected to the inner cavity of the second anti-overflow element. The second anti-overflow element blocks the external port of the second pipeline under its own weight, and the second through-hole abuts against the inner wall of the second pipeline. The first pipeline and the second pipeline are engaged, and the second anti-overflow element moves away from the external port of the second pipeline under the squeezing action of the first anti-overflow element.

The split-type refrigeration handle is as described above. The water-cooling assembly includes a water tank, inside which a water pump is installed. The outlet of the water pump is connected to the cooling pipeline. The negative pressure pump is connected to the negative pressure pipeline. A temperature sensor for monitoring the temperature of the refrigerated cup is detachably connected inside the refrigeration cup. The temperature sensor, the thermoelectric cooler, the water pump, and the negative pressure pump are all electrically connected to the main controller.

[0016] Compared with the prior art, the present invention has the following advantages and technical effects:

[0017] In operation, the opening side of the negative pressure chamber of the freezing cup is brought into contact with the part to be frozen, making the negative pressure chamber a sealed structure. Air is then extracted from the inside of the negative pressure chamber through a negative pressure pipeline, creating negative pressure inside. Under the action of negative pressure, human skin and fat enter the negative pressure chamber and come into contact with the inner wall of the freezing cup. The semiconductor refrigerator starts working, and the temperature of the cooling end of the semiconductor refrigerator decreases, exchanging heat with the contact surface of the freezing cup, thus lowering the temperature of the freezing cup. This cools the human skin and fat to a specified temperature, converting the triglycerides in the fat into solids. The solidified triglycerides age prematurely and are then gently eliminated and excreted from the body through normal metabolic processes. The heating end of the semiconductor refrigerator is cooled and dissipated through liquid cooling elements and cooling pipelines, ensuring the normal operation of the semiconductor refrigerator. This invention features a split-type freezing handle, consisting of a freezing cup and a handle body. The freezing cup and handle body are detachably connected by a connecting rod, enabling communication between the negative pressure chamber and negative pressure pipeline, as well as between the liquid cooling element and the cooling pipeline. By selecting a freezing cup of appropriate shape as needed, it can adapt to the needs of different parts of the human body. Different parts can be frozen without using different handles, reducing costs and improving work efficiency. Attached Figure Description

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other. The described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Referring to the accompanying drawings, the present invention provides a split-type freezing handle, including a freezing cup 1 and a handle body 5. The freezing cup 1 is provided with a negative pressure chamber 2 with an opening on one side. A semiconductor cooler 3 is provided on the side of the freezing cup 1 away from the opening. The cooling end of the semiconductor cooler 3 is in contact with the freezing cup 1, and the heating end of the semiconductor cooler 3 is in contact with a liquid cooling element 4. The handle body 5 is provided with a cooling pipe and a negative pressure pipe. The negative pressure chamber 2 and the negative pressure pipe, and the liquid cooling element 4 and the cooling pipe are detachably connected and conductive. The handle body 5 is rotatably connected to a connecting rod 6, and the side of the connecting rod 6 near the freezing cup 1 is detachably connected to the freezing cup 1.

[0034] When the handle of this embodiment is in operation, the opening side of the negative pressure chamber 2 of the freezing cup 1 is brought into contact with the part to be frozen, making the negative pressure chamber 2 a sealed structure. The air inside the negative pressure chamber 2 is extracted through the negative pressure pipeline, creating a negative pressure inside the negative pressure chamber 2. Under the action of negative pressure, human skin and fat enter the negative pressure chamber 2 and come into contact with the inner wall of the freezing cup 1. The semiconductor cooler 3 starts to work, and the temperature of the cooling end of the semiconductor cooler 3 decreases, and heat exchange occurs with the contact surface of the freezing cup 1, causing the temperature of the freezing cup 1 to decrease. This cools the human skin and fat to the specified temperature, converting the triglycerides in the fat into solids. The solidified triglycerides will age prematurely and are then gently eliminated and excreted from the body through normal metabolic processes. The heating end of the semiconductor cooler 3 is cooled and dissipated through the liquid cooling element 4 and cooling pipeline, ensuring that the semiconductor cooler 3 can work normally. This invention features a split-type freezing handle, consisting of a freezing cup 1 and a handle body 5. The freezing cup 1 and the handle body 5 are detachably connected by a connecting rod 6, enabling communication between the negative pressure chamber and the negative pressure pipeline, as well as between the liquid cooling element and the cooling pipeline. By selecting a freezing cup 1 of a suitable shape as needed, it can adapt to the needs of different parts of the human body. Different parts can be frozen without using different handles, reducing costs and improving work efficiency.

[0035] In this embodiment, the detachable connection between the connecting rod 6 and the freezing cup 1 can be achieved in various ways, such as threaded connection, plug-in connection, and snap-fit ​​connection. When the connecting rod 6 and the freezing cup 1 are connected by threads, a first thread is provided on the outer side of the connecting rod 6 near the freezing cup 1, and an installation groove is provided at the position corresponding to the freezing cup and the connecting rod 6. A second thread is provided inside the installation groove. The first thread and the second thread are matched to achieve the threaded connection between the connecting rod 6 and the freezing cup 1.

[0036] Preferably, a spiral groove 7 is provided on the outer side of the connecting rod 6 near the end of the freezing cup 1, and the spiral groove 7 is spirally arranged along the extension direction of the connecting rod 6; a snap-fit ​​groove 8 for accommodating the end of the connecting rod 6 is provided on the end of the freezing cup 1 near the connecting rod 6, and a limiting rod 9 is provided on the side wall of the snap-fit ​​groove 8, which is located on the rotation path of the spiral groove 7, with the end of the limiting rod 9 away from the snap-fit ​​groove 8 snapped into the spiral groove 7. In this application, when the connecting rod 6 and the freezing cup 1 are detachably connected using this structure, the connecting rod 6 is aligned with the snap-fit ​​groove 8, and the handle body 5 is moved closer to the freezing cup 1. During the movement, the connecting rod 6 is rotated, causing the inlet of the spiral groove 7 and the end of the limiting rod 9 away from the snap-fit ​​groove 8 to snap together. Then, the connecting rod 6 continues to rotate. Since the end of the limiting rod 9 away from the snap-fit ​​groove 8 is snapped into the spiral groove 7, the limiting rod 9 and the spiral groove 7 work together to decompose the force acting on the connecting rod 6 into a force perpendicular to the tangent of the contact point between the limiting rod 9 and the spiral groove 7, thus allowing the connecting rod 6 to rotate simultaneously. When the connecting rod 6 moves downward along its axis until its end reaches the designated position of the locking groove 8, the limiting rod 9 engages with the end of the spiral groove 7, thus connecting the connecting rod 6 to the handle body 5. When the freezing cup 1 needs to be removed from the handle body 5, the connecting rod 6 is rotated in the opposite direction (with the rotation direction of the connecting rod 6 during installation as the positive direction), causing the connecting rod 6 to rotate in the opposite direction until the limiting rod 9 separates from the spiral groove 7, thus separating the connecting rod 6 from the handle body 5. The operation is convenient and allows for quick installation and removal of the freezing cup 1 and the handle body 5.

[0037] In some embodiments, the thread helix angle of the spiral groove 7 is controlled to be less than or equal to the equivalent friction angle. The friction between the spiral groove 7 and the limiting rod 9 is sufficient to resist the loosening tendency caused by the axial load and realize thread self-locking. At this time, the limiting rod 9 can stay and be locked at any position of the spiral groove 7. It is not necessary to lock the limiting rod 9 at the end of the spiral groove 7 to ensure the connection strength between the connecting rod 6 and the freezing cup 1.

[0038] In a further optimized design, the section of the spiral groove 7 furthest from the freezing cup 1 is a smooth section. This smooth section of the spiral groove 7 is arranged circumferentially on the outer side of the connecting rod 6, and it is positioned on the cross-section of the connecting rod 6. Specifically, the surface of the smooth section of the spiral groove 7 is a plane, perpendicular to the axis of the connecting rod 6. When the end of the limiting rod 9 reaches the designated position of the locking groove 8, the connecting rod 6 continues to rotate, causing the end of the limiting rod 9 furthest from the locking groove 8 to engage with the smooth section of the spiral groove 7. This improves the tensile strength of the connecting rod 6, thereby enhancing the connection strength between the freezing cup 1 and the handle body 5. In some embodiments, two sets of limiting rods 9 are provided, symmetrically arranged about the central axis of the locking groove 8. Both sets of limiting rods 9 engage with and slide within the spiral groove 7, further improving the tensile strength of the connecting rod 6 and ensuring the connection strength between the freezing cup 1 and the handle body 5.

[0039] In this embodiment, the liquid cooling element 4 needs to exchange heat with the heating end of the thermoelectric cooler 3 to reduce the temperature of the heating end of the thermoelectric cooler 3 and ensure that the thermoelectric cooler 3 can work normally. The liquid cooling element 4 can adopt a tube structure, that is, a liquid cooling tube is arranged in contact with the heating end of the thermoelectric cooler 3. By continuously injecting coolant into the liquid cooling tube, the flowing coolant carries away the heat generated by the heating end of the thermoelectric cooler 3. Preferably, the liquid cooling element 4 is a liquid cooling box. One side of the liquid cooling box is in contact with the heating end of the thermoelectric cooler 3. Two sets of first pipes 10 are arranged on the side of the cooling box away from the heating end. The cooling pipes are provided with two sets of second pipes 11 arranged opposite to the two sets of first pipes 10. The opposite first pipes 10 and second pipes 11 are detachably connected and conductive. Compared with the liquid cooling tube, the liquid cooling box has a larger contact area with the heating end of the thermoelectric cooler 3, and the heat exchange efficiency is faster, which can quickly realize the cooling of the heating end of the thermoelectric cooler 3. Meanwhile, since the freezing cup 1 and the handle body 5 in this application are separate structures, when connecting them, the cooling tank and cooling pipes need to be connected and circulated. That is, the first pipe 10 and the second pipe 11, which are arranged opposite to each other, are detachably connected and circulated to continuously supply coolant to the liquid cooling tank and recover the heated coolant, thereby reducing the temperature of the coolant, ensuring the cooling effect of the liquid cooling element 4, and ensuring that the semiconductor refrigerator 3 can work normally. In this embodiment, the coolant can be water, which is green and pollution-free.

[0040] In a further optimized design, an anti-overflow assembly is provided between the first pipe 10 and the second pipe 11, which are positioned opposite each other. The anti-overflow assembly includes a spring 12 and a first anti-overflow element 13. The first anti-overflow element 13 is slidably disposed within the first pipe 10, and the spring 12 is disposed between the first anti-overflow element 13 and the liquid cooling tank. Under the elastic force of the spring 12, the first anti-overflow element 13 blocks the outer port of the first pipe 10. The first pipe 10 and the second pipe 11 are engaged. Under the squeezing action of the second pipe 11, the first anti-overflow element 13 overcomes the elastic force of the spring 12 and moves away from the outer port of the first pipe 10, thus maintaining the continuity between the first pipe 10 and the second pipe 11. In this embodiment, the anti-overflow assembly includes a spring 12 and a first anti-overflow element 13. The first anti-overflow element 13 is slidably disposed within the first pipe 10. Under the elastic force of the spring 12, the first anti-overflow element 13 blocks the outer port of the first pipe 10, keeping the first pipe 10 in a closed state and preventing the coolant inside the liquid cooling tank from overflowing. When the freezing cup 1 is connected to the handle body 5, the second pipe 11 is correspondingly arranged and abuttingly connected to the first anti-overflow element 13. Under the squeezing action of the second pipe 11, the first anti-overflow element 13 overcomes the elastic force of the spring 12 and moves away from the outer port of the first pipe 10. The first pipe 10 and the second pipe 11 are in a conductive state, so that the second pipe, the first pipe 10 and the liquid cooling box are in a conductive state. The cooling pipe supplies coolant to the liquid cooling box through the first pipe 10 and the second pipe 11, while recovering the heated coolant through another set of the first pipe 10 and the second pipe 11. When the freezing cup 1 is separated from the handle body 5, the squeezing force of the second pipe 11 on the first anti-overflow element 13 continues to decrease, and the elastic force of the spring 12 begins to dominate until the first anti-overflow element 13 blocks the outer port of the first pipe 10 under the elastic force of the spring 12, completing the disassembly of the freezing cup 1 and preventing coolant from overflowing through the anti-overflow component.

[0041] In this embodiment, the first overflow prevention element 13 can be either a spherical or tubular structure to achieve the overflow prevention function. When the first overflow prevention element 13 is a spherical structure, the inside of the first pipe 10 has a frustum-shaped cavity. The diameter of the outer port of the first pipe 10 is smaller than the diameter of the connection between the first pipe 10 and the liquid cooling box. The diameter of the first overflow prevention element 13 is larger than the diameter of the outer port of the first pipe 10, ensuring that the first overflow prevention element 13 can block the outer port of the first pipe 10. At the same time, the frustum-shaped cavity inside the first pipe ensures that when the first overflow prevention element 13 is away from the outer port of the first pipe 10, the first pipe 10 and the second pipe 11 can be connected. Meanwhile, the outer diameter of the second pipe 11 is less than or equal to the diameter of the outer port of the first pipe 10, which facilitates the second pipe 11 to apply compressive force to the first overflow prevention element 13.

[0042] Preferably, the first anti-overflow element 13 is a blind tube with its open end located near the outer port of the first pipe 10, and the closed end of the first anti-overflow element 13 abuts against the spring 12; a first conductive port 14 is provided on the side wall of the first anti-overflow element 13 near the closed end, and the first conductive port 14 is in communication with the inner cavity of the first anti-overflow element 13; when the first anti-overflow element 13 blocks the outer port of the first pipe 10 under the elastic force of the spring 12, the first conductive port 14 abuts against the inner wall of the first pipe 10; when the first pipe 10 and the second pipe 11 are in a conductive state, the first conductive port 14 is in communication with the inside of the liquid cooling box. In this embodiment, the first anti-overflow element 13 is a blind tube with its open end located near the outer port of the first pipe 10. Under the elastic force of the spring 12, the first conductive port 14 of the first anti-overflow element 13 abuts against the inner wall of the first pipe 10, thereby blocking the first conductive port 14 and achieving the sealing operation of the first pipe 10 to prevent coolant overflow. When the first anti-overflow element 13 moves away from the outer port of the first pipe 10 under the squeezing action of the second pipe 11, overcoming the elastic force of the spring 12, the first conduction port 14 and the interior of the liquid cooling tank become connected. Simultaneously, the cooling pipes supply coolant to the liquid cooling tank through the first pipe 10 and the second pipe 11, and recover the heated coolant through another set of first pipes 10 and second pipes 11. Compared to the spherical first anti-overflow element 13, the blind-tube-shaped first anti-overflow element 13 scheme adopted in this embodiment does not require additional limitation on the shape of the first pipe 10; it only needs to ensure that the first anti-overflow element 13 and the first pipe 10 are slidably connected while being in contact.

[0043] In this embodiment, a second anti-overflow element 15 is slidably disposed inside the second pipeline 11. The second anti-overflow element 15 is a blind pipe with its open end located on the side near the external port of the second pipeline 11, and its closed end located inside the second pipeline 11. A second through port 16 is provided on the side wall of the second anti-overflow element 15, and the second through port 16 is connected to the inner cavity of the second anti-overflow element 15. The second anti-overflow element 15 blocks the external port of the second pipeline 11 under its own weight, and the second through port 16 abuts against the inner wall of the second pipeline 11. The first pipeline 10 and the second pipeline 11 are engaged. The second anti-overflow element 15 moves away from the external port of the second pipeline 11 under the squeezing action of the first anti-overflow element 13, and the liquid cooling box, the inner cavity of the first anti-overflow element 13, the inner cavity of the second anti-overflow element 15, and the second pipeline 11 are connected. In this embodiment, the second anti-overflow element 15 is slidably disposed inside the second pipe 11. When the second pipe 11 is inclined downward, the second anti-overflow element 15 blocks the external port of the second pipe 11 under its own weight, and the second through port 16 abuts against the inner wall of the second pipe 11 to prevent coolant from flowing out from the external port of the second pipe 11. When the second pipe 11 is inclined upward, the coolant is retained in the cooling pipe under its own weight. When the first pipe 10 and the second pipe 11 are engaged, the second anti-overflow element 15 moves away from the external port of the second pipe 11 under the squeezing action of the first anti-overflow element 13. The liquid cooling tank, the inner cavity of the first anti-overflow element 13, the inner cavity of the second anti-overflow element 15, and the second pipe 11 are connected. The cooling pipe supplies coolant to the liquid cooling tank through the first pipe 10 and the second pipe 11, while the heated coolant is recovered through another set of first pipe 10 and second pipe 11.

[0044] In a further optimized design, a negative pressure hole 17 is provided on the side of the freezing cup 1 furthest from the opening. The negative pressure hole 17 is connected to a negative pressure pipeline, and a filter element 18 is detachably connected inside the negative pressure hole 17. In this embodiment, air is extracted from the negative pressure chamber 2 through the connection between the negative pressure hole 17 and the negative pressure pipeline, creating a negative pressure inside the chamber 2. Under this negative pressure, human skin and fat enter the negative pressure chamber 2 and come into contact with the inner wall of the freezing cup 1. Since the temperature of the inner wall of the freezing cup 1 can reach below zero degrees Celsius, to prevent frostbite and to lubricate the contact surface between the freezing cup 1 and the human body, a freezing film is often applied to the human skin and / or the inner wall of the freezing cup 1. The negative pressure environment causes the freezing film to be drawn into the negative pressure pipeline. In this application, a filter element 18 is detachably connected inside the negative pressure hole 17. The filter element 18 adsorbs the freezing film, preventing it from entering the negative pressure channel. In this embodiment, the filter element 18 contains a filter layer such as filter cotton or polyester fiber.

[0045] Further optimizing the design, the freezing cup 1 includes a metal cup body, with a silicone layer 19 detachably connected to both the cup opening and the inner wall of the metal cup body. In this embodiment, the freezing cup 1 has a silicone layer 19 detachably connected to both the cup opening and the inner wall of the metal cup body. The silicone layer 19 provides elastic protection for human skin while reducing energy transfer efficiency, preventing the temperature of the freezing cup 1 from becoming too low when in contact with the human body, and also provides good lubrication when used in conjunction with the antifreeze film.

[0046] A refrigeration device includes a split-type refrigeration handle, a water-cooling assembly, a negative pressure pump, and a main controller. The split-type refrigeration handle is as described above. The water-cooling assembly includes a water tank, inside which a water pump is installed, with the pump's outlet connected to a cooling pipe. The negative pressure pump is connected to a negative pressure pipe. A temperature sensor for monitoring the temperature of the refrigeration cup 1 is detachably connected inside the refrigeration cup 1. The temperature sensor, the semiconductor cooler 3, the water pump, and the negative pressure pump are all electrically connected to the main controller. The main controller controls the cooling efficiency of the semiconductor cooler 3, the power of the water pump, and the power of the negative pressure pump based on the data received from the temperature sensor. The refrigeration weight loss device disclosed in this invention includes a main body and a split-type refrigeration handle. The water-cooling assembly and the negative pressure pump are both located inside the main body. The water-cooling assembly continuously supplies coolant to the liquid cooling tank and recovers the heated coolant, reducing the coolant temperature and ensuring the cooling effect of the liquid cooling element 4, thus ensuring the normal operation of the semiconductor cooler 3. The negative pressure pump and the negative pressure pipe create a negative pressure in the negative pressure chamber 2. The main controller is located inside the main body of the device or inside the split-type freezing handle. Based on the data received from the temperature sensor, the main controller controls the cooling efficiency of the semiconductor cooler 3, the power of the water pump, and the power of the negative pressure pump, thereby precisely controlling the temperature of the freezing cup 1.

[0047] In some embodiments, the cryogenic weight loss device further includes an information input module. The information input module includes information such as freezing time, the set temperature of the freezing cup 1, the negative pressure time and power, and the flow rate and temperature of the coolant in the cooling pipe. The main controller controls the cooling efficiency and duration of the semiconductor refrigerator 3, the power and duration of the water pump, and the power and duration of the negative pressure pump based on the information input by the information input module and the data from the temperature sensor, thereby precisely controlling the freezing temperature and freezing time of the freezing cup 1.

[0048] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this application; at the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this application.
