Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a handle and a photoelectric therapeutic apparatus. Background Art

[0002] At present, the circuit mainboards of most photoelectric therapy devices are usually set inside the handheld part, that is, inside the handle. Since the circuit mainboard generates heat when working, in order to prevent the heat generated by the circuit mainboard from causing the temperature of the handle to be too high, a heat dissipation device needs to be set at the handle. The currently commonly used fan heat dissipation method requires a large space and needs to open heat dissipation holes. In order to meet the heat dissipation requirements, the size of the handle is relatively large, and the power of the fan is also set relatively large. The operation of the fan consumes more electric energy of the photoelectric therapy device, which leads to a lower battery life of the photoelectric therapy device. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] The temperature of the handheld part of the photoelectric therapy device cannot exceed the maximum set value. In order to take away the heat generated inside the handle 100, the current common practice is to set heat dissipation holes on the handle 100 and install fans, heat dissipation blocks and other structures. However, this method brings about the problem that the operation of the fan occupies more electric energy of the photoelectric therapy device, which in turn leads to a lower battery life of the photoelectric therapy device. The utility model chooses not to set fans and heat dissipation holes, and can also meet the temperature requirements of the handle 100 of the photoelectric therapy device.

[0036] The utility model provides a handle 100, which aims to improve the battery life of a photoelectric therapeutic device.

[0037] See also Figure 1 In one embodiment of the utility model, the handle 100 includes a heating component 10, a shielding cover 20 and a heat absorbing member 30. The heating component 10 has a heating surface 121. The shielding cover 20 is connected to the heating component 10. The shielding cover 20 is arranged on the heating surface 121 of the heating component 10. The heat absorbing member 30 is arranged on a side of the shielding cover 20 close to and / or away from the heating component 10. The heat absorbing member 30 absorbs the heat generated by the heating component 10.

[0038] It can be understood that the handle 100 serves as the handheld part of the photoelectric therapy device. A cavity is provided inside the shielding cover 20, and an opening is provided on one side of the shielding cover 20. The heat absorbing element 30 enters the cavity of the shielding cover 20 through the opening. The opening cover of the shielding cover 20 is provided on the heating surface 121 of the heating component 10, so that the heat absorbing element 30 can always absorb the heat of the heating component 10. The heat absorbing element 30 has the characteristic that its temperature does not change significantly even after absorbing a large amount of heat, so that the heat absorbing element 30 can absorb the heat generated by the heating component 10, thereby reducing the temperature change outside the handle 100.

[0039] The heat absorbing element 30 may include but is not limited to phase change materials or materials with large specific heat capacity. Phase change materials (such as paraffin, etc.) can change their own form (such as solid to liquid) after absorbing heat, so that even after absorbing a large amount of heat, their own temperature changes little. After absorbing heat, materials with large specific heat capacity (such as water, etc.), due to their large specific heat capacity, can absorb more heat for each same temperature rise compared to materials with low specific heat capacity. Therefore, through the above two embodiments, the heat dissipation requirements inside the handle can be met, and heat can be prevented from being transferred to the outer surface of the handle.

[0040] It should be noted that the handle 100 of the present invention can be combined with conventional heat dissipation methods to achieve better heat dissipation effects, such as combining a fan and heat dissipation holes with the handle 100 of the present invention; or combining a heat dissipation block with the handle 100 of the present invention.

[0041] In an embodiment of the utility model, the heat absorption element 30 can be made of magnesium oxide (MgO) powder, silica gel with high specific heat capacity, and moldable insulating material with high specific heat capacity. In this way, the heat generated by the heating component 10 is absorbed by utilizing the high heat storage density of magnesium oxide (MgO), and the magnesium oxide (MgO) powder will not have obvious temperature changes at this time.

[0042] In an embodiment of the utility model, the heat absorbing element 30 can be made of phase change material, and the characteristic of the phase change material changing its shape after absorbing heat is utilized, so that the heat generated by the heating component 10 becomes energy of the changed shape of the heat absorbing material after being absorbed by the heat absorbing element 30, thereby reducing the heat reaching the outside of the handle 100.

[0043] In an embodiment of the utility model, a plurality of heat absorbing components 30 can be provided. The plurality of heat absorbing components 30 can not only be all provided on the side of the shielding cover 20 close to the heating component 10, but also can be all provided on the side of the shielding cover 20 away from the heating component 10, and a plurality of heat absorbing components 30 can also be provided on both sides of the shielding cover 20.

[0044] Further, see Figure 1 In one embodiment, the heat absorption member 30 includes a first heat absorption material 31, the shielding cover 20 is sealed and connected to the heating surface 121 of the heating component 10, and the first heat absorption material 31 is filled in the internal space formed by the shielding cover 20 and the heating component 10, wherein the first heat absorption material 31 is an insulating material.

[0045] Optionally, AB glue is used to seal the seam between the shielding cover 20 and the heating component 10 .

[0046] It can be understood that the first heat absorbing material 31 is filled inside the shielding cover 20, and the first heat absorbing material 31 absorbs heat and changes its shape inside the shielding cover 20, and then slowly dissipates the heat to restore its original shape. At the same time, the first heat absorbing material 31 is an insulating material, so that even if the first heat absorbing material 31 contacts the heating surface 121 of the heating component 10, it will not cause a short circuit between the components on the heating component 10, thereby improving the safety of the heating component 10.

[0047] In an embodiment of the utility model, the first heat-absorbing material 31 can be a solid-solid phase change material, such as polyols (pentaerythritol, neopentyl glycol, trimethylolethane, etc.) and organic polymers (high-density polyethylene, etc.); or a solid-liquid phase change material, mainly including higher aliphatic hydrocarbons (n-hexadecane, n-octadecane, paraffin, etc.), fatty acids and their esters (stearic acid, palmitic acid, etc.) and polymers (polyethylene glycol, etc.).

[0048] Furthermore, the first heat absorbing material 31 is any one or more combinations of paraffin, distilled water, silica gel, and magnesium oxide powder.

[0049] In this way, the first heat absorbing material 31 can be a combination of multiple materials, so that the first heat absorbing material 31 can have the advantages of various materials and work together on the heating component 10. The first heat absorbing material 31 can be configured according to actual usage to improve the applicability of the first heat absorbing material 31.

[0050] Further, see Figure 1 In one embodiment, the heat absorption member 30 further includes an insulating container 33, which is filled with a second heat absorption material 32. The insulating container 33 is disposed on the shielding cover 20 close to and / or away from the heating component 10; wherein the first heat absorption material 31 and the second heat absorption material 32 are the same or different.

[0051] In this way, the second heat absorbing material 32 is first filled into the insulating container 33 , and the insulating container 33 filled with the second heat absorbing material 32 can be more conveniently arranged inside the shielding cover 20 , and the shape of the second heat absorbing material 32 can be regularized.

[0052] The second heat absorbing material 32 may be a solid-solid phase change material, such as polyols (pentaerythritol, neopentyl glycol, trimethylolethane, etc.), inorganic salts (Li2SO4, KHF2, etc.) and organic polymers (high-density polyethylene, etc.); or a solid-liquid phase change material, mainly including higher aliphatic hydrocarbons (n-hexadecane, n-octadecane, paraffin, etc.), fatty acids and their esters (stearic acid, palmitic acid, etc.), crystalline hydrated salts (Na2SO4·10H2O, Mn(NO3)2·6H2O, etc.), molten salts (LiF, NaF, CaF2, etc.), and polymers (polyethylene glycol, etc.). Of course, the second heat absorbing material 32 may also be a combination of any one or more of paraffin, distilled water, silica gel, and magnesium oxide powder.

[0053] In an embodiment of the utility model, the insulating container 33 can be made of a PE bag, that is, a polyethylene bag. The polyethylene bag has the physical properties of being light and soft, so that it can be stretched to a certain extent, so that the polyethylene bag can adapt to the internal space of a shielding cover 20 of various shapes for easy installation; at the same time, the polyethylene bag also has good electrical insulation, so that when the polyethylene bag contacts the heating component 10, it will not short-circuit the components on the heating component 10.

[0054] Further, see Figure 1 In one embodiment, when the insulating container 33 is disposed between the shielding cover 20 and the heating component 10 , the insulating container 33 contacts the heating surface 121 and absorbs the heat generated by the heating component 10 through the second heat absorbing material 32 .

[0055] It can be understood that the insulating container 33 containing the second heat absorbing material 32 absorbs the heat generated by the heating component 10 in two ways. The first way is that the insulating container 33 is not in contact with the heating component 10, and the heating component 10 transfers heat to the air through the air inside the shielding cover 20 as a medium, and the second heat absorbing material 32 absorbs the heat in the air; the second way is that the insulating container 33 is in contact with the heating surface 121, and the second heat absorbing material 32 directly absorbs heat from the heating component 10. However, no matter which heat absorption method is used, the insulating container 33 containing the second heat absorbing material 32 saves more space than traditional heat dissipation methods (such as fan heat dissipation), and also eliminates the need for the setting of ventilation holes, so that the handle can be designed to be more compact and have better waterproof performance.

[0056] In the embodiment of the utility model, the insulating container 33 containing the second heat absorbing material 32 can occupy the entire space inside the shielding cover 20, that is, the inside of the shielding cover 20 is filled with the second heat absorbing material 32, so that the maximum upper limit of heat absorption inside the shielding cover 20 can be increased, and the temperature outside the handle 100 can be further reduced.

[0057] Further, see Figure 1In one embodiment, there are a plurality of insulating containers 33 , and the insulating containers 33 are respectively disposed on the inner and outer surfaces of the shielding cover 20 .

[0058] In this configuration, a plurality of insulating containers 33 are filled with the second heat absorbing material 32, and the plurality of insulating containers 33 are respectively arranged on the inner and outer surfaces of the shielding cover 20, which not only optimizes the arrangement position of the second heat absorbing material 32, but also can achieve a greater heat absorption efficiency with less second heat absorbing material 32, thereby improving the heat absorption efficiency of the second heat absorbing material 32.

[0059] In an embodiment of the utility model, two insulating containers 33 are provided on the outer surface of the shielding cover 20. The two insulating containers 33 are respectively located at the top of the shielding cover 20 and one end of the shielding cover 20 close to the battery 13. In this way, relatively more insulating containers 33 can be arranged in the limited space inside the shell, thereby improving the heat absorption effect as much as possible.

[0060] Further, see Figure 1 In one embodiment, the first heat absorbing material 31 and the second heat absorbing material 32 are both phase change materials or high specific heat capacity materials.

[0061] It should be noted that since the second heat absorbing material 32 has an insulating container 33 as its outer shell, the second heat absorbing material 32 is in indirect contact with the heating component 10 through the insulating container 33, and the insulating container 33 is in direct contact with the heating component 10. The insulating container 33 avoids short-circuiting of various components on the heating component 10, so the second heat absorbing material 32 does not need to be made of insulating material.

[0062] Further, see Figure 1 In one embodiment, the handle 100 includes a shell, the heating component 10 is installed in the shell, and the heat absorption member 30 is located between the heating component 10 and the shell to prevent the heat generated by the heating component 10 from being transferred to the shell.

[0063] In order to make the shielding cover 20 meet the limitations of the internal space of the shell and avoid interference between the shielding cover 20 and the shell during actual use, the width of the shielding cover 20 can be gradually reduced from the end close to the heating component 10 to the end away from the heating component 10. In this way, there are more heat absorbers 30 inside the shielding cover 20 at the end close to the heating component 10, avoiding the heat absorber 30 being too far away from the heating component 10 and resulting in lower heat absorption efficiency. At the same time, the volume of the shell can be set smaller accordingly.

[0064] Further, see Figure 1In one embodiment, the heating component 10 includes a main control circuit board 11, a radio frequency circuit board 12 and a battery 13. The main control circuit board 11 is installed close to the inner wall of the shell. The shielding cover 20 is arranged on the heating surface 121 of the radio frequency circuit board 12. The radio frequency circuit board 12 is located between the shielding cover 20 and the main control circuit board 11. The radio frequency circuit board 12 is electrically connected to the main control circuit board 11. The battery 13 is electrically connected to the main control circuit board 11 and is used to supply power to the radio frequency circuit board 12 and the main control circuit board 11.

[0065] It can be understood that the RF circuit board 12 is the main heat-generating circuit board, while the main control circuit board 11 generates almost no heat. Various heating elements are concentrated on one side of the RF circuit board 12, namely the heating surface 121. The shielding cover 20 is covered on the heating surface 121 of the RF circuit board 12 to concentrate on absorbing the heat generated by the heating component 10.

[0066] In an embodiment of the present invention, the RF circuit board 12 is inserted into the main control circuit board 11 through an adapter, and the RF circuit board 12 and the main control circuit board 11 are spaced apart so that the tiny heat generated by the main control circuit board 11 can be quickly dissipated through the gap.

[0067] In an embodiment of the utility model, the RF circuit board 12 and the main control circuit board 11 are arranged at the central position inside the shell, so that the installation of the shielding cover 20 can make full use of the limited internal space of the shell and reduce the design volume of the shell. At the same time, the heat generated by the RF circuit board 12 located in the center needs to pass through a longer path to reach the outside of the shell, further reducing the temperature change of the handle 100.

[0068] The present utility model also proposes a photoelectric therapy device, which includes a handle 100. The specific structure of the handle 100 refers to the above embodiment. Since the photoelectric therapy device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0069] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
