Technical Field
[0001] This application belongs to the field of physiotherapy device technology, and in particular relates to a cold compress physiotherapy device. Background Technology
[0002] Existing cold compress therapy devices generate heat during the therapy process, while providing cooling. This heat needs to be dissipated through heat dissipation holes, i.e., hot air is expelled from the heat dissipation holes.
[0003] During the physiotherapy process, the user holds the casing of the cold compress physiotherapy device in their hand, which causes the hot air to blow onto their hand, causing discomfort and affecting the user experience. Utility Model Content
[0004] The purpose of this application is to provide a cold compress therapy device that aims to solve the problem that the hot air emitted by the cold compress therapy device blows onto the user's hands, causing discomfort.
[0005] To achieve the above objectives, the technical solution adopted in this application is: a cold compress therapy device, comprising a shell, a cooler, a flow guiding structure, and an airflow driver. One end of the shell has an installation port. The cooler is disposed at the installation port of the shell and has a cooling surface and a heating surface. The cooling surface is exposed at the installation port for applying cold compresses to the skin. The flow guiding structure is disposed inside the shell, dividing the interior of the shell into an air inlet duct and an air outlet duct. The heating surface is located within the air inlet duct. The airflow driver is disposed inside the shell and configured to drive airflow through the air inlet duct, past the heating surface, and into the air outlet duct. The shell is provided with a ventilation structure, which communicates with both the air inlet and air outlet ducts. The opening direction of the ventilation structure is configured to be offset from the intended gripping area of the shell.
[0006] In some embodiments, the intended gripping area includes two opposing main gripping surfaces, which are disposed on both sides of the housing along a first direction; a venting structure is disposed on both sides of the housing along a second direction, the first direction being perpendicular to the second direction, and the main gripping surfaces intersecting the side with the venting structure at an angle.
[0007] In some embodiments, the cooling surface and the heating surface are arranged sequentially along a third direction, and the third direction is set at an angle with the first direction and the second direction; the ventilation structure includes a plurality of ventilation holes, which are spaced apart on the housing along the third direction. Alternatively, the ventilation structure includes an elongated vent that extends along a third direction on the housing.
[0008] In some embodiments, the cold compress therapy device further includes a partition disposed within the housing. The partition is connected between the airflow guiding structure and the inner wall of the housing. The partition and the airflow guiding structure divide the interior of the housing into independent air inlet ducts and air outlet ducts. The partition also divides the ventilation structure into an air inlet structure communicating with the air inlet duct and an air outlet structure communicating with the air outlet duct. The air inlet structure and the air outlet structure are arranged at intervals along a first direction.
[0009] In some embodiments, the flow guide structure is connected to the inner wall of the housing, and the flow guide structure and the inner wall of the housing enclose a portion of the exhaust duct. The end of the flow guide structure away from the cooler is provided with two curved portions extending away from each other in a second direction. One side of the inner wall of the housing is provided with two protrusions corresponding to the curved portions. The protrusions are connected to the partition. The two protrusions abut against the two curved portions to block the airflow from flowing to the air intake structure. The two curved portions are spaced from the other side of the inner wall of the housing to allow the airflow to flow to the air outlet structure.
[0010] In some embodiments, the cold compress therapy device further includes a circuit board, which is fixedly disposed in the airflow guide structure and located in the exhaust duct. The circuit board is electrically connected to the airflow driver. The circuit board is provided with a button, which is disposed through the housing and exposed.
[0011] In some embodiments, the cold compress therapy device also includes a battery, which is electrically connected to a circuit board. The flow guiding structure includes a main body and a partition plate connected to the main body. The main body is connected to the inner wall of the housing, and the partition plate is located in the exhaust duct. The main body and the partition plate enclose an installation space for fixing the battery.
[0012] In some embodiments, the cold compress therapy device further includes a heat sink, and the housing further includes an end shell, which is installed at the mounting port. The cooler and the heat sink are both installed on the end shell, and one end of the heat sink is connected to the heating surface to transfer heat, while the other end of the heat sink is connected to the airflow driver.
[0013] In some embodiments, the cold compress therapy device further includes an LED light source and a light guide. The LED light source is disposed on the end shell and surrounds the cooling surface. The LED light source is electrically connected to the circuit board. The light guide is disposed on the end shell and covers the LED light source to guide the light emitted by the LED light source to the skin.
[0014] In some embodiments, the cold compress therapy device further includes a cooling conductor, which is attached to the cooling surface for contact with the skin.
[0015] This application has at least the following beneficial effects: When a user applies a cooling therapy device to a specific area, they hold the intended grip area and place the cooling surface on the area. The airflow actuator then drives airflow, carrying away the heat concentrated on the heating surface through the exhaust duct and out through the ventilation structure. Because the opening of the ventilation structure is configured to be offset from the intended grip area of the casing, the blown-out hot air avoids contact with the user's hands, thus solving the problem of discomfort caused by hot air blowing directly onto the user's hands.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0023] Combination such as Figures 8 to 10 , Figure 12 As shown in the figure, the X direction is the first direction, the Y direction is the second direction, and the Z direction is the third direction.
[0024] like Figures 1 to 10 As shown, the purpose of this application is to provide a cold compress therapy device, which aims to solve the problem that the hot air emitted by the cold compress therapy device blows onto the hands, causing discomfort to the user.
[0025] To achieve the above objectives, such as Figures 1 to 6 , Figure 8 and Figure 9 As shown, the cold compress therapy device provided in the embodiments of this application includes a housing 10, a cooler 20, a flow guiding structure 30, and an airflow driver 40. One end of the housing 10 has a mounting port 101. The cooler 20 is disposed at the mounting port 101 of the housing 10. The cooler 20 has a cooling surface 21 and a heating surface 22. When the cooler 20 is powered on, it performs cooling operation, concentrating the cooling energy on the cooling surface 21, while the heat generated during cooling is concentrated on the heating surface 22. The cooling surface 21 is exposed at the mounting port 101 for applying cold compresses to the skin. Furthermore, the flow guiding structure 30 is disposed inside the housing 10, dividing the interior of the housing 10 into an air inlet duct 301 and an air outlet duct 302. The heating surface 22 is located inside the air inlet duct 301. The airflow driver 40 is disposed inside the housing 10 and is configured to drive airflow through the air inlet duct 301, past the heating surface 22, and into the air outlet duct 302. The housing 10 is provided with a ventilation structure 102, which is connected to both the air inlet duct 301 and the air outlet duct 302. The opening direction of the ventilation structure 102 is configured to be offset from the intended gripping area 103 of the housing 10.
[0026] like Figure 7 As shown, when a user applies the cold compress therapy device to a specific area, the user removes the protective cover 90, exposing the cooling surface 21. The user then applies the cooling surface 21 to the affected area for cold compress therapy. When the device is not in use, the user replaces the protective cover 90 on the housing 10, covering the cooling surface 21 to prevent it from being contaminated by dust or debris, thus keeping the cooling surface 21 clean.
[0027] When a user applies a cold compress therapy device to a specific area, the user holds the intended gripping area 103 and applies the cooling surface 21 to the area. At this time, the airflow driver 40 drives the airflow, carrying away the heat concentrated on the heating surface 22 through the exhaust duct 302 and blowing it out through the ventilation structure 102. Because the opening direction of the ventilation structure 102 is configured to be offset from the intended gripping area 103 of the housing 10, the blown hot air avoids the user's hand, thus solving the problem of discomfort caused by hot air blowing onto the user's hand.
[0028] The intended gripping area 103 includes two main gripping surfaces arranged opposite to each other, located on both sides of the housing 10 along a first direction X; the ventilation structure 102 is located on both sides of the housing 10 along a second direction Y, with the first direction X perpendicular to the second direction Y, and the main gripping surfaces intersecting the sides with the ventilation structure 102 at an angle. Specifically, as shown... Figures 1 to 3 As shown, in this cold compress therapy device, the housing 10 includes a first half-shell 11 and a second half-shell 12. The first half-shell 11 and the second half-shell 12 overlap each other to form an installation port 101. Assembly is performed by overlapping, and the first half-shell 11 and the second half-shell 12 are locked together by a snap-fit mechanism, reducing the need for screws and making assembly convenient and efficient. Furthermore, the plane containing the seam between the first half-shell 11 and the second half-shell 12 is the plane of symmetry of their outlines. The other end of the housing 10 opposite to the installation port 101 is the bottom end 104. The direction perpendicular to the installation port 101 and parallel to the plane of symmetry is the width direction of the housing 10, and the direction perpendicular to the plane of symmetry is the thickness direction of the housing 10. The thickness of the housing 10 is less than its width. The first direction X can be the thickness direction. Correspondingly, the opposite sides of the first half-shell 11 and the second half-shell 12 are both provided with the main grip surface, which makes it convenient for users to grip the shell. When gripping, the thumb abuts against one of the main grip surfaces, and the other four fingers abut against the other main grip surface. In other words, the overall shape of the cold compress therapy device is flat, which is a shape structure suitable for users' palms and fingers to hold (pinch), conforms to ergonomic design, and improves the user's grip comfort when using the cold compress therapy device.
[0029] The second direction Y can be the width direction, and the ventilation structure 102 is located on both sides of the width direction of the shell 10. Specifically, the shell surfaces of the first half-shell 11 and the second half-shell 12 are curved, and the seam line between the first half-shell 11 and the second half-shell 12 is curved. The user grips the shell 10 through the bottom end 104, and the ventilation structure 102 is located in the direction of the web between the thumb and index finger and the hypothenar eminence of the palm. Thus, the user's palm and fingers avoid the ventilation structures 102 on both sides, and the blown hot air will not come into contact with the user's palm and fingers, avoiding the burning discomfort caused by the hot air.
[0030] The cooling surface 21 and the heating surface 22 are arranged sequentially along a third direction Z, which forms an angle with the first direction X and the second direction Y. The ventilation structure 102 includes a plurality of ventilation holes, which are spaced apart on the housing 10 along the third direction Z; or, the ventilation structure 102 includes an elongated ventilation opening extending on the housing 10 along the third direction Z. The angle between the third direction Z and the first direction X and the second direction Y can be approximately perpendicular, for example, 80°, 90°, or 100°. Specifically, the third direction Z is the length direction. In some embodiments, such as... Figures 1 to 9 As shown, the ventilation structure 102 includes multiple ventilation holes, which are spaced apart along the extension direction of the seam line between the first half-shell 11 and the second half-shell 12. The direction of the seam line is the third direction Z. In this embodiment, the ventilation structure 102 composed of multiple ventilation holes not only allows for smooth airflow, but also the small aperture of any single ventilation hole prevents some fine debris from entering the interior of the housing 10, thus improving the internal cleanliness of the cold compress therapy device.
[0031] In some embodiments, the ventilation structure 102 includes an elongated vent, the extension direction of which is consistent with the extension direction of the seam line between the first half-shell 11 and the second half-shell 12, i.e., the third direction Z. In other words, the ventilation structure 102 is a slender slit opening, which not only allows for smooth airflow, but also prevents small debris from entering the housing 10, thus improving the internal cleanliness of the cold compress therapy device.
[0032] In the embodiments of this application, the ventilation structure 102 includes an air inlet structure 1021 and an air outlet structure 1022, which are arranged side by side.
[0033] like Figures 4 to 6 , Figure 8 and Figure 10As shown, in some embodiments, the flow guiding structure 30 can be connected to the inner wall of the housing 10 (i.e., the inner wall of the second half-shell 12), and the flow guiding structure 30 and the inner wall of the first half-shell 11 enclose a portion of the exhaust duct 302. Alternatively, in other embodiments, the flow guiding structure 30 can be connected to the inner wall of the first half-shell 11, and the flow guiding structure 30 and the inner wall of the second half-shell 12 enclose a portion of the exhaust duct 302. After the flow guiding structure 30 is installed on the housing 10, the flow guiding structure 30 forms a relatively connected inlet end 311 and outlet end 312. The inlet end 311 is connected to the air intake structure 1021, and the outlet end 312 is connected to the air outlet structure 1022. That is, the duct enclosed by the flow guiding structure 30 and the inner wall of the housing 10 serves as part of the exhaust duct 302. Furthermore, as... Figure 4 and Figure 9 As shown, the end of the flow guiding structure 30 away from the cooler 20 is provided with two curved portions 33 extending away from each other in the width direction. Two protrusions 14 are provided on one side of the inner wall of the housing 10 (e.g., the inner wall of the first half-shell 11). The protrusions 14 are connected to the partition 13. The two protrusions 14 abut against the two curved portions 33 to block the airflow from flowing to the air intake structure 1021. The two curved portions 33 are spaced from the inner wall of the other side of the housing (e.g., the inner wall of the second half-shell 12) to allow the airflow to flow to the air outlet structure 1022. In this embodiment, under the driving action of the airflow driver 40, the airflow enters the air intake duct 301 from the air intake structure 1021. The airflow flows along the air intake duct 301 and absorbs heat through the heating surface 22. The airflow that has absorbed heat flows from the inlet end 311 into the exhaust duct 302. The hot airflow flows along the exhaust duct 302 and is finally discharged from the air outlet structure 1022. The airflow circulates in this way, enabling the cooler 20 to operate stably and ensuring that the cooling surface 21 always maintains sufficient cooling capacity for applying cold compresses to the corresponding areas.
[0034] like Figures 4 to 6 , Figure 9 and Figure 10 As shown, the cold compress therapy device also includes a circuit board 50, which is fixedly mounted on the airflow guide structure 30 and located within the exhaust duct 302. This allows the airflow to absorb the resistance heat generated by the circuit board 50 during operation, preventing heat buildup on the electronic components and potential burnout. Furthermore, the circuit board 50 is electrically connected to the airflow driver 40, and it includes a button 51 that is protruding from and exposed within the housing 10. This allows the user to directly operate the button 51 with their thumb or forefinger while holding the intended grip area 103, controlling the cold compress therapy device to start, stop, or adjust the cooling level of the cooler 20, making operation convenient.
[0035] like Figure 10As shown, the cold compress therapy device also includes a battery 60, which is electrically connected to the circuit board 50 and provides power. Furthermore, the battery 60 is a rechargeable battery capable of repeated charging and discharging, making it convenient to use. Thus, after the battery 60 is fully charged, the user can carry the cold compress therapy device with them, making it easy to use.
[0036] To improve the heat dissipation efficiency of the heat-generating surface 22, such as Figures 4 to 6 , Figures 8 to 10 As shown, the cold compress therapy device also includes a heat sink 71, and the housing 10 includes an end shell 15, which is installed at the mounting port 101. Both the cooler 20 and the heat sink 71 are installed on the end shell 15. In other words, the end shell 15 acts as a connecting component, installing the cooler 20 and the heat sink 71 to the mounting port 101 of the housing 10. One end of the heat sink 71 is connected to the heating surface 22 to transfer heat, and the other end is connected to the airflow driver 40. Thus, when the airflow flows along the inlet duct 301 and passes through the heat sink 71, the airflow absorbs the heat transferred from the heating surface 22 to the heat sink 71. Then, the heat-absorbed airflow flows from the inlet end 311 into the exhaust duct 302. The heat sink 71 allows for faster absorption of heat from the heating surface 22, and the fin structure on the heat sink 71 increases the airflow contact area, allowing the airflow to absorb more heat and carry it away, thereby improving heat dissipation efficiency.
[0037] Furthermore, in order to ensure that the cooling energy from the cooling surface 21 can be applied more evenly to the corresponding area, such as... Figures 4 to 6 , Figures 8 to 10 As shown, the cold compress therapy device also includes a cooling conductor 72, which is attached to the cooling surface 21 for contact with the skin. In this way, the cooling conductor 72 evenly transfers the cold energy from the cooling surface 21 to the corresponding area to achieve cold compress therapy. Furthermore, the surface area of the cooling conductor 72 in contact with the skin is larger than that of the cooling surface 21 directly contacting the skin, thereby expanding the cold compress area for the corresponding area and improving the effect of the cold compress therapy.
[0038] To further enhance the therapeutic effect on the corresponding areas of the user's body, such as Figures 4 to 6 , Figures 8 to 10 As shown, the cold compress therapy device also includes an LED light source 81 and a light guide 82. The LED light source 81 is located on the end shell and surrounds the cooling surface 21. The LED light source 81 is electrically connected to the circuit board 50. The light guide 82 is located on the end shell and covers the LED light source 81, guiding the light emitted by the LED light source 81 to the skin. In other words, while applying cold compress therapy to the corresponding area of the user, the therapeutic light emitted by the LED light source 81 irradiates the corresponding area, thereby achieving the phototherapy function. The phototherapy stimulates blood circulation in the area, improving the therapeutic effect.
[0039] The cold compress therapy device also includes a partition 13 disposed within the housing 10. The partition 13 is connected between the airflow guiding structure 30 and the inner wall of the housing 10. The partition 13 and the airflow guiding structure 30 divide the interior of the housing 10 into independent air inlet ducts 301 and air outlet ducts 302. The partition 13 also divides the ventilation structure 102 into an air inlet structure 1021 communicating with the air inlet duct 301 and an air outlet structure 1022 communicating with the air outlet duct 302. The air inlet structure 1021 and the air outlet structure 1022 are arranged at intervals along a first direction X. In some embodiments, such as Figure 11 As shown, the first half-shell 11 or the second half-shell 12 is provided with a partition 13, which abuts against the outer wall of the airflow guiding structure 30. The partition 13 and the airflow guiding structure 30 divide the interior of the shell 10 into independent air inlet ducts 301 and air outlet ducts 302. A portion of the ventilation structure 102 provided in the first half-shell 11 is an air inlet structure 1021 connected to the air inlet duct 301, and another portion of the ventilation structure 102 provided in the second half-shell 12 is an air outlet structure 1022 connected to the air outlet duct 302. In this way, the partition 13 separates the parallel air inlet structure 1021 and air outlet structure 1022, so that the cold air flowing into the air inlet duct 301 is separated from the hot air flowing out of the air outlet duct 302, avoiding the mixing of hot and cold airflows, thereby improving the airflow to carry away the heat of the heat sink 71 and improving the heat dissipation effect.
[0040] In some embodiments, such as Figure 12 As shown, the airflow guiding structure 30 includes a main body 31 and a partition plate 32 connected to the main body 31. The main body 31 is connected to the inner wall of the first half-shell 11 or the second half-shell 12. The partition plate 32 is located within the exhaust duct 302. The main body 31 and the partition plate 32 enclose an installation space 34 for fixing the battery 60. This embodiment fully utilizes the assembly space formed by the cooperation between the housing 10 and the airflow guiding structure 30 to install the battery 60. Furthermore, the partition plate 32 isolates the flowing hot airflow, preventing the hot airflow from directly blowing on the battery 60, thereby extending the service life of the battery 60.
[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
