Description

Technical Field

[0001] This utility model relates to the field of laser therapy equipment technology, and in particular to a treatment head, treatment handle and laser therapy instrument. Background Technology

[0002] The clinical application of laser therapy devices is increasing. These devices work by applying laser beams to the patient's skin to perform treatments such as hair removal, freckle removal, and skin whitening. A typical laser therapy device includes a main unit, a laser transmission device, and a treatment handpiece. The handpiece consists of a gripper and a treatment head that comes into contact with the patient's skin. During operation, the laser generates a significant amount of heat on the skin, causing a rise in skin temperature and resulting in pain.

[0003] In some handpieces, before the laser irradiates the skin, it passes through a transducer on the treatment head and then irradiates the patient's skin. The transducer can be a sapphire glass plate or a ruby ​​glass plate, depending on the treatment needs. The transducer contacts the patient's skin. In order to reduce the pain caused by laser irradiation, a semiconductor cooling plate is used to cool the transducer. The transducer cools the skin after contacting it, thus reducing the patient's pain.

[0004] However, when the transmission element is exposed to the air and cooled by the semiconductor cooling chip, it will produce a lot of condensation, which will seriously affect the laser transmittance and the treatment effect. Utility Model Content

[0039] This utility model proposes a treatment head 100.

[0040] Please see Figure 1 In one embodiment of this utility model, the treatment head 100 includes a support 1, a transmissive element 2, and a transmissive cover 3. The support 1 is provided with a laser emission port 1a. The transmissive element 2 is connected to the support 1 and is located on the light emission path of the laser emission port 1a. A cooling plate is provided around the periphery of the transmissive element 2. The transmissive cover 3 is provided on the support 1 and is located on the light emission path of the laser emission port 1a. The transmissive cover 3 seals and shields the transmissive element 2 to form a closed space between the transmissive cover 3 and the transmissive element 2. An air inlet 4b and an air outlet 5b are provided on the inner wall of the closed space to communicate with the outside. The air inlet 4b and the air outlet 5b are used to communicate with the drying device 200 to remove moisture in the closed space.

[0041] In this embodiment, the support 1 is the supporting structure of the treatment head 100. The support 1 is used to connect with the treatment handle, etc., and the treatment handle can be held by the operator. The treatment head 100 is provided with a laser emission port 1a for the laser to pass through. After the laser emitted during treatment passes through the laser emission port 1a, it passes through the transmission cover 3 and the transmission element 2 in sequence before irradiating the human skin. Please refer to [reference needed]. Figure 1 The laser beam shown is 100A.

[0042] The transmitting element 2 is the laser transmission medium, typically made of sapphire or ruby ​​glass, which can be selected according to treatment needs; this embodiment does not impose any limitations on this. A cooling plate is provided around the periphery of the transmitting element 2 to cool it and reduce pain caused by laser irradiation. The material selection for the transmitting element 2 can also consider light transmittance and thermal conductivity to reduce laser loss and facilitate rapid heat conduction during cooling. The cooling plate can be a semiconductor cooler that directly cools the element; alternatively, it can be cooled by a refrigerant circulation pipe that surrounds the transmitting element 2, with a refrigerant flowing inside to cool it.

[0043] The transmission cover 3 is mounted on the support 1 and located on the light emission path of the laser exit port 1a. Its main function is to seal and shield the transmission element 2, forming a closed space between them. The material of the transmission cover 3 must have good transparency to ensure normal laser transmission. Alternatively, it can be partially transparent, with only the portion of the transmission cover 3 located on the light transmission path being transparent. The transmission cover 3 can be mounted on the support 1 or directly on the transmission element 2 to form a closed space. An air inlet 4b and an air outlet 5b are provided on the inner wall of the closed space. The air outlet 5b and the air inlet 4b can be located on the support 1 or the transmission cover 3. The air inlet 4b and the air outlet 5b communicate with the drying device 200 to remove moisture from the closed space.

[0044] Specifically, such as Figure 1 As shown, the support 1 includes a cylindrical fixing part at the top, an annular mounting part at the bottom, and a connecting part connecting the fixing part and the mounting part. The fixing part is used to fix it to the treatment handle, and the annular mounting part is used to fix it to the circular transmissive element 2. A cooling element or the like can be installed inside the annular mounting part. A certain distance is maintained between the top of the transmissive cover 3 and the transmissive element 2 to ensure that the temperature of the transmissive cover 3 is close to room temperature and to avoid the generation of condensation. The transmissive cover 3 can be bonded to the support 1 or the transmissive element 2 with a sealing adhesive to ensure the airtightness of the enclosed space. The air inlet 4b and the air outlet 5b are connected to the drying device 200, and the operation of the drying device 200 absorbs the moisture in the enclosed space. The position and size of the air inlet 4b and the air outlet 5b need to be reasonably designed to ensure smooth airflow and achieve the effect of rapid moisture removal.

[0045] Considering that when the transmitting element 2 is cooled by the cooling plate, its surface temperature is lower than the temperature of the surrounding air, water vapor in the air will condense on the surface of the transmitting element 2. This invention avoids the formation of condensation by isolating the transmitting element 2 from the outside air and using the drying device 200 to remove moisture from the enclosed space, ensuring the dryness and cleanliness of the surface of the transmitting element 2, thereby guaranteeing efficient laser transmission. At the same time, the cooling effect of the transmitting element 2 is not affected, achieving the dual purpose of cooling and preventing condensation.

[0046] Before treatment, the air inlet and outlet are connected to the drying device, which then absorbs moisture from the enclosed space. Since the side of the transmissive element facing away from the laser emission port is in contact with the patient's skin, and the side facing the laser emission port is sealed by the transmissive cover to isolate it from the outside air, and the moisture in the enclosed space is eliminated by the drying device, no condensation occurs on the side of the transmissive element facing the laser emission port.

[0047] Furthermore, in one embodiment of the present invention, the treatment head 100 further includes a first connecting tube and a second connecting tube. The first connecting tube is connected to the air inlet 4b, and the second connecting tube is connected to the air outlet 5b. The first connecting tube and the second connecting tube are used to communicate with the drying device 200.

[0048] In this embodiment, the first and second connecting pipes are used to connect the drying device 200 to the enclosed space, allowing air circulation. The dried air is then returned to the enclosed space to prevent negative pressure in the enclosed space from causing the transmission element 2 to rupture. In practical applications, moisture in the enclosed space needs to be effectively removed to prevent condensation. One condition for condensation is the presence of water molecules in the air. However, if the air in the enclosed space is extracted, creating a vacuum, negative pressure will be generated, putting excessive pressure on the transmission element 2. The transmission element 2 is typically made of ruby ​​or sapphire glass, and a large pressure difference between its two sides may even cause it to rupture. Therefore, in this embodiment, the air in the enclosed space is dried to remove water molecules, preventing condensation.

[0049] Specifically, in this embodiment, the first connecting pipe introduces the dry air generated by the drying device 200 into the enclosed space through the air inlet 4b, and the second connecting pipe discharges the humid air in the enclosed space through the air outlet 5b and sends it back to the drying device 200 for drying. The dried air is then transported back into the enclosed space through the first connecting pipe and the air inlet 4b. Therefore, this embodiment ensures that the air can circulate and prevents negative pressure from being generated in the enclosed space.

[0050] Further, please refer to Figures 1 to 4 In one embodiment of the present invention, an air intake channel 4a is formed between the first connecting pipe and the air intake hole 4b, and a first partition 6 is provided in the air intake channel 4a; an air outlet channel 5a is also formed between the second connecting pipe and the air outlet hole 5b, and a second partition 7 is provided in the air outlet channel 5a.

[0051] In practical applications, besides preventing negative pressure and removing moisture from the enclosed space, the impact of dust on treatment effectiveness also needs to be considered. Dust entering the enclosed space can affect laser transmission. Furthermore, excessive moisture increases the burden on the drying device 200, prolongs extraction time, and affects the device's startup speed. Therefore, a structure is needed to reduce the entry of dust and moisture into the enclosed space.

[0052] In this embodiment, an air intake channel 4a is formed between the first connecting pipe and the air inlet 4b, and a first partition 6 is provided inside the air intake channel 4a. The function of the first partition 6 is to reduce the entry of dust and moisture into the enclosed space. An air outlet channel 5a is formed between the second connecting pipe and the air outlet 5b, and a second partition 7 is provided inside the air outlet channel 5a. The function of the second partition 7 is to prevent dust and moisture from flowing back into the enclosed space. Specifically, the transmission cover 3 is connected to the bracket 1 and covers the transmission element 2 and part of the bracket. Therefore, the part of the bracket, the transmission element 2, and the transmission cover 3 enclose a closed space. The bracket 1 has an air inlet 4b and an air outlet 5b on the side facing the closed space. The bracket 1 has an air intake channel 4a that connects the air inlet 4b to the outside space. The first connecting pipe can be connected to the inner wall of the air intake channel 4a by means of insertion, snap-fit, etc., so that the first connecting pipe is connected to the air inlet 4b to deliver dry air to the enclosed space. The bracket 1 is also provided with an air outlet channel 5a that connects the air outlet 5b to the outside space. The second connecting pipe can be connected to the inner wall of the air outlet channel 5a by means of plugging or snapping, so that the second connecting pipe can be connected to the air outlet 5b to absorb water vapor in the enclosed space and realize air circulation.

[0053] For example, please refer to Figure 2 The first partition 6 is a baffle that matches the internal shape and size of the air intake channel 4a. For example, when the cross-section of the air intake channel 4a is circular, the first partition 6 can be a circular baffle that matches the inner wall of the air intake channel 4a, and one end of the first partition 6 is hinged to the inner wall of the air intake channel 4a. In this way, the first partition 6 can rotate relative to the inner wall of the air intake channel 4a to open or close the air intake channel 4a, thereby preventing dust or moisture from entering the enclosed space. It should be noted that when the first partition 6 rotates, it gradually moves closer to the air inlet, that is, it opens towards the air inlet. This allows the first connecting pipe to push the first partition 6 to open the air intake channel 4a when it is inserted into the air intake channel 4a, or the airflow to push the first partition 6 to open the first channel when the drying device 200 is activated. Furthermore, the top of the first partition 6 can be hinged to the inner wall of the air intake channel 4a. Thus, when the first connecting pipe is pulled out or the drying device 200 is turned off, the first partition 6 can automatically reset under its own weight to close the air intake channel 4a, preventing dust or moisture from entering the enclosed space. Alternatively, a spring or similar device can be used to automatically reset the first partition 6. Exemplarily, pivots can be provided at opposite ends of the first partition 6, allowing the first partition 6 to rotate around the pivots until it is parallel to the airflow direction, thereby opening the air intake channel 4a. Understandably, the second partition 7 can be configured with reference to the above exemplary description of the first partition 6, and will not be repeated here. Note that you should refer to... Figure 3 and Figure 4If the second connecting pipe is used to push the second partition 7 to open, the opening direction of the second partition 7 is towards the enclosed space (i.e., Figure 2 (as shown); if the second partition 7 is driven by airflow, the opening direction of the second partition 7 should be opposite to the enclosed space to adapt to the direction of airflow (i.e., Figure 4 (As shown).

[0054] This embodiment effectively reduces the entry of dust and moisture into the enclosed space by setting a first separator 6 and a second separator 7 in the air inlet channel 4a and the air outlet channel 5a, respectively, thereby improving the laser transmission effect. It also reduces the burden on the drying device 200 and shortens the equipment startup time. This design not only improves the treatment effect but also enhances the reliability and operating efficiency of the equipment.

[0055] Further, please refer to Figures 2 to 4 In one embodiment of the present invention, the first separator 6 has a first rebound portion 63 and a first blocking portion 61. The first separator 6 has an open state and a closed state. In the open state, the first blocking portion 61 compresses the first rebound portion 63 to make the air intake channel 4a unobstructed. In the closed state, the first rebound portion 63 pushes the first blocking portion 61 to block the air intake channel 4a. The second separator 7 has a second rebound portion 73 and a second blocking portion 71. The second separator 7 has an open state and a closed state. In the open state, the second blocking portion 71 compresses the second rebound portion 73 to make the air outlet channel 5a unobstructed. In the closed state, the second rebound portion 73 pushes the second blocking portion 71 to block the air outlet channel 5a.

[0056] In this embodiment, to ensure that the first partition 6 and the second partition 7 can be reset in a timely manner and to prevent dust and moisture from entering the enclosed space, the first partition 6 has a first spring-loaded portion 63, and the second partition 7 has a second spring-loaded portion 73. Taking the first partition 6 as an example, please refer to... Figure 2 The first separator 6 includes a first rebound portion 63 and a first blocking portion 61. The first rebound portion 63 can be made of an elastic material (such as rubber or silicone), possessing good elasticity and resilience. The first blocking portion 61 can be a partition made of materials such as plastic. Both the first separator 6 and the second separator 7 have an open state and a closed state. In the open state, the first blocking portion 61 is pushed, causing it to rotate relative to the inner wall of the air intake passage 4a and compress the first rebound portion 63, thus unblocking the passage. In the closed state, the first rebound portion 63 pushes the first blocking portion 61 to block the passage.

[0057] For details, please refer to Figure 2The first separator 6 also includes a first mounting ring 62. An annular groove extending circumferentially along the air intake channel 4a is provided within the air intake channel 4a, and the first mounting ring 62 is confined within the annular groove. A first blocking part 61 is located on one side of the first mounting ring 62 and is connected to the first mounting ring 62 via a first spring-loaded part 63. It should be noted that the mounting ring, in addition to enabling the first separator 6 to be installed within the air intake channel 4a, also serves to limit the position of the first blocking part 61. In the closed state, the first blocking part 61 abuts against the side of the first mounting ring 62 facing the enclosed space. Through the cooperation of the first spring-loaded part 63 and the first blocking part 61, the first blocking part 61 automatically resets. When dry air enters, the first blocking part 61 is compressed, clearing the passage; when the airflow stops or reverses, the first spring-loaded part 63 pushes the first blocking part 61 to block the air intake channel 4a, preventing dust and moisture from flowing back. Understandably, the second separator 7 includes a second mounting ring 72, a second spring-loaded part 73, and a second blocking part 71. Its installation method can be referred to the first separator 6 and the above embodiment, and will not be described again.

[0058] This embodiment incorporates a rebound section and a blocking section, allowing the separator to automatically switch between open and closed states based on changes in airflow direction and pressure. During normal airflow, the blocking section is compressed, ensuring unobstructed passage; when airflow stops or reverses, the rebound section pushes the blocking section, blocking the passage. This design effectively prevents dust and moisture from entering the enclosed space, while reducing the load on the drying device 200 and improving the equipment's start-up speed.

[0059] Furthermore, in one embodiment of this utility model, both the first connecting pipe and the second connecting pipe are at least partially flexible pipes.

[0060] In this embodiment, both the first and second connecting tubes are at least partially flexible tubes. This means that flexible tubes can be used in areas requiring movement or as a whole. The flexible tubes are connected to the inner wall of the air inlet channel 4a or the air outlet channel 5a via connectors or similar means. This design allows the connecting tubes to have a greater range of motion during use, thus providing greater convenience for medical personnel or operators in actual operation. For example, when treating a patient, the operator can flexibly adjust the direction and angle of the connecting tube as needed, ensuring that the treatment head 100 can be accurately aligned with the treatment area, while avoiding restrictions on operation due to the rigidity of the connecting tube. Furthermore, the flexible tube design reduces the pulling between the connecting tube and the treatment head 100 or the drying device 200 caused by equipment movement or changes in patient position, further improving the stability of the equipment and the safety of operation.

[0061] Further, please refer to Figure 1In one embodiment of the present invention, the transmission cover 3 includes a transmission part 31 and a cylindrical heat insulation part 32. The two ends of the heat insulation part 32 are respectively connected to the transmission part 31 and the transmission element 2 to form a closed space.

[0062] In this embodiment, the heat insulation part 32 can be made of low thermal conductivity materials such as heat-insulating plastic, heat-insulating rubber, or composite heat-insulating materials. These materials can form an effective heat insulation layer between the transmission part 31 and the transmission element 2, reducing heat transfer. The heat insulation part 32 has a cylindrical structure and fits tightly against the periphery of the transmission part 31. The connection between the heat insulation part 32 and the transmission part 31 can be achieved by bonding or other methods. By providing the heat insulation part 32, heat transfer between the transmission part 31 and the transmission element 2 is effectively reduced, thereby ensuring that the temperature of the transmission part 31 is maintained at a level close to room temperature. This design not only avoids condensation in the transmission part 31 due to excessively low temperature, but also further improves the stability and reliability of the treatment head 100. At the same time, the cylindrical structure of the heat insulation part 32 can better connect with the transmission part 31 and the transmission element 2, forming a stable closed space, ensuring efficient laser transmission and stable treatment effect during treatment.

[0063] This utility model also proposes a treatment handle, which includes a gripping hand and a treatment head 100 as described in any of the above embodiments. The gripping hand is connected to the end of the support 1 away from the transmission element 2. The specific structure of the treatment head 100 is as described in the above embodiments. Since this treatment handle 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.

[0064] In this embodiment, to facilitate the operator's grip and operation, the grip is connected to the end of the support 1 away from the transmission element 2. The operator can rotate or tilt the handle to align the treatment head 100 with the target area, thereby achieving precise and efficient treatment.

[0065] Furthermore, the connection between the handpiece and the support 1 can be detachable, facilitating the replacement and maintenance of the treatment head 100. For example, different types of treatment heads 100 can be used to meet different treatment functions, such as hair removal, freckle removal, or skin whitening. At the same time, the detachable design also facilitates the separate cleaning and disinfection of the treatment head 100 and the handpiece, further improving the hygiene and safety of the equipment.

[0066] This utility model also proposes a laser therapy device, which includes a drying device 200 and a treatment handle as described in the above embodiments. The drying device 200 includes an air pump 210 and a drying chamber 240. The air pump 210 has an exhaust pipe 220 and an intake pipe 230. The drying chamber 240 is disposed on the intake pipe 230. The intake pipe 230 and the exhaust pipe 220 are respectively connected to the air outlet 5b and the air inlet 4b. The drying device 200 is disposed on the grip or the main unit.

[0067] The specific structure of the treatment handle is as described in the above embodiments. Since this laser 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.

[0068] In this embodiment, the air pump 210 provides airflow power. The exhaust pipe 220 of the air pump 210 is connected to the air inlet 4b of the treatment head 100 to deliver dried air into the enclosed space. The suction pipe 230 is connected to the air outlet 5b of the treatment head 100 to extract humid air from the enclosed space. A drying chamber 240 is installed on the suction pipe 230 to remove moisture from the air. It is filled with a desiccant, such as silica gel or activated alumina, which effectively adsorbs moisture from the air, ensuring that the air entering the enclosed space remains dry.

[0069] Specifically, the exhaust pipe 220 is connected to the air intake channel 4a and air intake port 4b of the treatment head 100 via a first connecting pipe. Dried air enters the first connecting pipe through the exhaust pipe 220 and then enters the enclosed space through the air intake port 4b. The suction pipe 230 is connected to the air outlet channel 5a and air outlet 5b of the treatment head 100 via a second connecting pipe. Humid air in the enclosed space enters the second connecting pipe through the air outlet 5b, and is then drawn out by the air pump 210 through the suction pipe 230 and sent to the drying chamber 240 for drying. This connection method ensures that humid air can be discharged and dried in a timely manner, preventing moisture accumulation in the enclosed space.

[0070] Through the coordinated operation of the air pump 210 and the drying chamber 240, the drying device 200 can continuously deliver dry air into the enclosed space and extract humid air for drying. This efficient drying cycle ensures that the enclosed space remains dry at all times, preventing the formation of condensation and thus improving the laser transmission efficiency and treatment effect. Simultaneously, through the design of the first and second connecting pipes, a stable airflow circulation system is formed between the drying device 200 and the treatment head 100, preventing negative pressure from forming in the enclosed space and protecting the transmission element 2 from damage. The drying device 200 can be mounted on the handgrip; it can also be mounted on the main unit; the air pump can be mounted on the main unit and the drying chamber on the handgrip; or the drying chamber can be mounted on the main unit and the air pump on the handgrip. In some embodiments, when the treatment handle has a negative pressure function, its negative pressure module can be the aforementioned air pump.

[0071] Furthermore, in one embodiment of this utility model, the drying chamber 240 and the suction pipe 230 are detachably connected. Please refer to [link / reference]. Figures 5 to 6The drying device 200 also includes a quick connector 250, which includes a male connector 251 and a female connector 252 that can be plugged into each other. One of the male connector 251 and the female connector 252 is located in the drying chamber 240, and the other is located in the suction pipe 230; or, the drying chamber 240 is screwed to the suction pipe 230.

[0072] The drying chamber 240 and the suction pipe 230 are detachably connected, facilitating the replacement and maintenance of the drying chamber 240. Specifically, the drying device 200 also includes a quick connector 250, which comprises a male connector 251 and a female connector 252 that can be plugged into each other. The male connector 251 and the female connector 252 can be respectively installed on the drying chamber 240 and the suction pipe 230, or vice versa. This design allows the drying chamber 240 to be quickly connected or disconnected from the suction pipe 230, facilitating user replacement or cleaning as needed. Alternatively, the drying chamber 240 and the suction pipe 230 can also be connected by a screw thread. The screw thread connection provides good sealing and stability, ensuring that the drying chamber 240 will not loosen due to airflow impact during use. Simultaneously, the screw thread connection allows users to easily disassemble and install the equipment without the need for special tools, further improving the ease of maintenance. By employing a quick-connector 250 or a screw-in detachable connection, the drying chamber 240 of this invention can be easily connected to or separated from the suction pipe 230. This design not only facilitates users to regularly replace or clean the drying chamber 240 to maintain the drying effect of the desiccant, but also allows for quick replacement by directly using a pre-filled desiccant drying chamber 240 to replace the old drying chamber 240, improving replacement efficiency and making it suitable for situations with urgent usage needs.

[0073] Furthermore, in one embodiment of the present invention, the drying chamber 240 is provided with filter holes at both ends that are connected to the suction pipe 230.

[0074] In this embodiment, the drying chamber 240 is provided with filter holes at both ends that communicate with the air intake pipe 230. The main function of the filter holes is to confine the desiccant within the drying chamber 240 without obstructing airflow. This design ensures that the desiccant can effectively absorb moisture from the air without affecting the normal operation of the equipment due to desiccant particles leaking into the air intake pipe 230.

[0075] Specifically, multiple filter holes can be installed and arranged in a circular or rectangular array at both ends of the drying chamber 240. The hole size should be appropriate to prevent desiccant particle leakage while ensuring smooth air passage. Alternatively, metal mesh, plastic mesh, or other structures can be installed at both ends of the drying chamber 240 to effectively prevent desiccant particles from entering the intake pipe 230.

[0076] Further, please refer to Figure 6In one embodiment of the present invention, the drying chamber 240 is provided with a chamber door 241 and a feeding port 240a. The chamber door 241 is movably connected to the drying chamber 240 and closes the feeding port 240a.

[0077] In this embodiment, one side of the door 241 is movably connected to the drying chamber 240 via a hinged connection, sliding connection, or other connection methods. The other side of the door 241 is detachably connected to the drying chamber 240 via clips, screws, etc., and can be temporarily locked. This allows the door 241 to open and close flexibly, facilitating user operation. The feeding port 240a is an opening for adding or replacing desiccant. Its size and shape design must ensure that the desiccant can smoothly enter the drying chamber 240, while the door 241 can tightly seal the feeding port 240a when closed to prevent air leakage. Regularly replacing the desiccant ensures that the drying device 200 maintains a good drying effect, because the desiccant gradually loses its drying ability after absorbing moisture; timely replacement of the desiccant is key to ensuring equipment performance. The sealing design of the door 241 and the feeding port 240a prevents air leakage and ensures the normal operation of the drying device 200. A sealing ring can be installed around the periphery of the silo door 241 or the periphery of the feeding port 240a. When the silo door 241 is closed, the silo door 241 presses against the sealing ring to achieve a seal.

[0078] Furthermore, in one embodiment of the present invention, a moisture-absorbing element is provided inside the drying chamber 240; the moisture-absorbing element includes a plurality of spaced sheet-shaped desiccants; or, the moisture-absorbing element includes a plurality of granular desiccants, with gaps formed between the plurality of granular desiccants.

[0079] In this embodiment, the sheet desiccant can be made of silica gel sheets, molecular sieve sheets, or other materials with hygroscopic properties. The sheet desiccant is spaced apart to allow air to pass through smoothly, thereby improving drying efficiency. The granular desiccant can be silica gel granules, activated carbon granules, or other materials with hygroscopic properties. The gaps between the granular desiccant particles allow air to flow freely while providing a large specific surface area for moisture absorption. Both types of desiccants are easy to replace and refill; users can easily add or replace desiccants as needed without complicated procedures, further improving the ease of equipment maintenance. Using either sheet or granular desiccants effectively improves drying efficiency, facilitates replacement and maintenance, and adapts to different usage requirements.
