Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a water tank device and a treatment instrument. Background Technology

[0002] Therapeutic devices generate a lot of heat when they are in operation, and an effective cooling system is needed to maintain the normal operation and lifespan of the equipment. Therefore, therapeutic devices are usually equipped with water tanks and water circuit systems for cooling and heat dissipation.

[0003] The water tank on the treatment device is simple and has only one function: water storage. The water system has a filter, but when the water flows back to the tank, it does not undergo sufficient heat exchange before entering the water system again. At the same time, due to the space limitations of the water system and the treatment device, only a filter with low water resistance can be used. This means that only larger particles can be filtered, while smaller particles cannot be filtered, resulting in increased water resistance and increased pressure loss, which directly reduces the water pressure. As a result, the water in the entire water system will have multiple problems such as high temperature, many impurities, and low water pressure. Utility Model Content

[0004] The main purpose of this utility model is to provide a water tank device that aims to solve the problem of excessive impurities in the entire water system by setting a filter component inside the water tank device.

The guide section of each filter plate is aligned with the filter section of the adjacent filter plate. Any two adjacent flow spaces are interconnected through the filter sections, so that multiple flow spaces are connected to form a flow channel, the flow channel being able to connect the inlet and the outlet.

[0006] In one embodiment of the present invention, the filter assembly includes at least two filter units, and each filter unit is arranged in a direction from near the water inlet to away from the water inlet; The filtration efficiency of the filter plate of the filter unit located far from the water inlet is greater than that of the filter plate of the filter unit located close to the water inlet.

[0007] In one embodiment of this utility model, the guide section of the filter plate located near the water inlet is aligned with the water inlet, and the filter section and guide section of each filter plate are arranged along the height direction of the housing, and each filter plate is arranged along the length-height direction of the housing.

[0008] In one embodiment of this utility model, the filter plate located near the water inlet is inclined away from the water inlet, and the cross-section of the flow space formed by the filter plate and the side wall of the water tank gradually decreases from the direction near the water inlet to the direction away from the water inlet.

[0024] Please see Figure 1 and Figure 2 The water tank device includes a tank body 10, which has a receiving space with an inlet 10a and an outlet 10b. The water tank device also includes a filter assembly 20, which has multiple filter plates 21. Each filter plate 21 is disposed in the receiving space. Any two adjacent filter plates 21 are spaced apart to form a flow space 20a. Each filter plate 21 includes a guide section 211 and a filter section 212. The filter section 212 is disposed at the end of the guide section 211. The guide section 211 of each filter plate 21 is aligned with the filter section 212 of the adjacent filter plate 21. Any two adjacent flow spaces 20a are interconnected through the filter section 212 so that multiple flow spaces 20a are connected to form a flow channel. The flow channel can connect the inlet 10a and the outlet 10b.

[0025] In this utility model, the water tank device forms a continuous flow channel connecting the inlet 10a and the outlet 10b by alternately arranging multiple filter plates 21, each containing a guide section 211 and a filter section 212, within the tank body 10. This flow channel with multiple turns forces the water flow to change direction multiple times, significantly extending its flow path within the water tank. Multiple staggered filter sections are set along the flow path to better filter impurities in the water flow. Furthermore, it increases the contact time and contact area between the fluid medium and the tank body 10 or the heat dissipation structure, thereby improving heat transfer efficiency. Due to the increased residence time in the extended channel, heat is more fully transferred to the external environment, effectively solving the problem of insufficient heat exchange leading to excessively high water temperature in traditional water tanks.

[0026] Specifically, the housing 10 has an internal partition plate 11 for supporting the filter plate 21. The partition plate 11 and the cavity wall of the housing 10 form a channel for fluid flow. The two ends of this channel are connected to the outlet 10b of the housing 10 and the filter holes of the filter section 212, respectively. Thus, by setting up the partition plate 11, while allowing fluid flow, it also serves to fix the filter plate 21. It is understood that the filter plate 21 and the partition plate 11 can be connected by welding, plugging, or other methods. Welding allows the filter plate 21 to be connected to the partition plate 11. The strong connection between the isolation plates 11 prevents the filter plate 21 from becoming loose. The filter plate 21 and the isolation plate 11 can be detached by plugging them in, which is convenient for replacing damaged or filter plates 21 with different filtration efficiencies. Of course, when the filter plate 21 and the isolation plate 11 are connected by plugging, sealing rings or serrated sealing surfaces can be used to achieve a sealed connection. It is understood that when the water tank device is used in different therapeutic instruments, the fluid medium can be water, 0.9% sodium chloride solution, coolant, etc., and there is no limitation here.

[0027] To address the issue of numerous impurities in the entire water system, a filter assembly 20 is installed within the housing 10. In one embodiment, the filter assembly 20 comprises N filter plates 21, where N is an odd number. The filter plates 21 are spaced apart to form (N-1) flow spaces 20a. Simultaneously, the filter plates 21 at both ends form a flow space 20a with the cavity wall of the housing 10. Each filter plate 21 includes a guide section 211 and a filter section 212. The guide section 211 is a plate-like structure used to guide water flow to the filter section 212. The filter section 212 has filter holes, which are coated with filter cotton made of polymer material to ensure the filtration efficiency of the water tank device. Filtration efficiency represents the filter's ability to capture target particles and is an important indicator of filter performance. For example, if the filter section 212 has a filtration efficiency of 99.5% for 1-micron particles, it means that 99.5% of micron-sized particles in the water flow are filtered out. This filter captures impurities by setting filter sections 212 on the filter plate 21, which connect all the flow spaces 20a to form a complete flow channel. The flow channel connects the inlet 10a and the outlet 10b. When the fluid medium of the water system in the therapeutic device flows into the housing 10 through the inlet 10a, impurities in the fluid medium can be filtered out by the filtration action of multiple filter sections 212, improving the purity of the fluid medium. At the same time, the housing 10 has a larger capacity than the water system, so converting the filter in the water system into a filter assembly 20 in the housing 10 can reduce the pressure of the water flow, thereby increasing the water pressure of the entire water system. Furthermore, the filter sections 212 are located at the ends of the guide sections 211, and the guide sections 211 of each filter plate 21 are aligned with the filter sections 212 of the adjacent filter plate 21. In this way, the flow channel formed in the housing 10 can form multiple turning parts under the conduction action of the filter plates 21. Please refer to [link to relevant documentation]. Figure 1When the filter section 212 and the guide section 211 of each filter plate 21 are arranged along the first direction, and multiple filter plates 21 are arranged along the second direction, the fluid medium flowing into the inlet 10a first passes through the guide section 211 and flows downward along the first direction into the first flow space 20a to the filter section 212. Then, it is filtered in the filter section 212 and flows into the second flow space 20a. In the second flow space 20a, the fluid medium passes through the guide section 211 and flows upward along the first direction to the filter section 212 for filtration and then flows into the second flow space 20a after multiple changes in direction. During this process, by changing the flow direction of the water multiple times and increasing the channel length, the flow time of the fluid medium in the tank 10 is effectively extended. The residence time of the fluid medium in the tank 10 is increased, and impurities in the fluid medium are filtered better. In addition, more time can be spent on heat exchange to achieve the purpose of lowering the water temperature; at the same time, when the fluid medium flows through the flow channel that can change direction multiple times, it forms turbulence through repeated circulation, which ensures uniform heat exchange of the fluid medium and reduces turbulence resistance during the flow process, thus helping to reduce water resistance and stabilize water pressure.

[0028] In the above embodiments, each filter plate 21 has the same structure, with its two ends fixed to the top and bottom of the receiving space, respectively. If the filter section 212 is placed upright at the top and inverted at the bottom, then the arrangement order of the multiple filter plates 21 in the above embodiments is upright and inverted in sequence. In some embodiments, if multiple (two or more) adjacent filter plates 21 are placed upright / inverted at the same time, and then multiple (two or more) adjacent filter plates 21 are placed inverted / upright, then according to the flow path of the flow channel, the corresponding part of the flow space in the adjacent guide section of the filter plates that are placed upright / inverted is almost not part of the flow channel. The flow efficiency of water in this part of the flow space is very low. Therefore, multiple adjacent upright / inverted filter plates 21 are regarded as one filter plate 21.

[0029] Further, the filter assembly 20 includes at least two filter units, each filter unit arranged along a direction from near the inlet 10a to away from the inlet 10a. The filter plate 21 of the filter unit located away from the inlet 10a has a higher filtration efficiency than the filter plate 21 of the filter unit located near the inlet 10a. In one embodiment, the filter assembly 20 includes a primary filter unit 2a, a secondary filter unit 2b, and a tertiary filter unit 2c. The primary filter unit 2a is located near the inlet 10a, and the tertiary filter unit 2c is located away from the inlet 10a. The secondary filter unit 2b is located between the primary filter unit 2a and the tertiary filter unit 2c. The filtration efficiency of the filter plate 21 of the tertiary filter unit 2c is higher than that of the filter plate 21 of the secondary filter unit 2b, and the filtration efficiency of the filter plate 21 of the secondary filter unit 2b is higher than that of the filter plate 21 of the primary filter unit 2a. For more details, please refer to [link to relevant documentation]. Figure 1 and Figure 3The primary filtration unit 2a, secondary filtration unit 2b, and tertiary filtration unit 2c are arranged along the second direction. Each filtration unit has multiple filter plates 21. The primary filtration unit 2a is the coarse filtration layer of the filtration assembly 20, and its filtration section 212 has a relatively low filtration efficiency. It is mainly used to intercept larger particles in the fluid medium. In one embodiment, the filter plate 21 of the primary filtration unit 2a is usually made of a coarser filter material, such as stainless steel wire mesh or nylon filter mesh, with a larger pore size to allow a larger fluid flow rate to pass through, while effectively blocking large particulate impurities. This ensures that larger particulate impurities are removed before the fluid medium enters the subsequent filtration units, effectively protecting the subsequent filtration units from the impact of large particles. The secondary filtration unit 2b is the fine filtration layer of the filtration assembly 20, and its filtration section 212 has a higher filtration efficiency than the primary filtration unit 2a. Finer filter materials, such as microporous membranes or activated carbon filters, are used to further remove smaller particles and some dissolved impurities from the fluid medium. The filter plate 21 of the secondary filter unit 2b has a smaller pore size, which can intercept tiny particles that the primary filter unit 2a failed to capture, further improving the purity of the fluid medium. The tertiary filter unit 2c is the fine filtration layer of the filter assembly 20, with the highest filtration efficiency. Its filter section 212 usually uses high-precision filter materials, such as ultrafiltration membranes or reverse osmosis membranes, which can effectively remove tiny particles, bacteria and other harmful substances from the fluid medium. The pore size of the tertiary filter unit 2c is the smallest, ensuring that the fluid medium reaches an extremely high purity standard after three stages of filtration. The primary filter unit 2a, the secondary filter unit 2b and the tertiary filter unit 2c are arranged in order of increasing filtration efficiency to form a complete filtration system. When the fluid medium enters the water tank through inlet 10a, it first passes through the primary filtration unit 2a to remove large particles; then it flows into the secondary filtration unit 2b to further remove smaller particles and some dissolved impurities; finally, it passes through the tertiary filtration unit 2c to remove tiny particles and harmful substances. This multi-stage filtration design not only improves filtration efficiency but also reduces the burden on individual filtration units by progressively decreasing the pore size, extending the service life of the filter plates 21. Simultaneously, the coordination of the multi-stage filtration units ensures that the fluid medium maintains stable pressure during filtration, reducing water pressure loss. In this embodiment, the filter assembly 2020 includes a first filter unit and a second filter unit. The first filter unit is located near the inlet 10a, and the second filter unit is located away from the inlet 10a relative to the first filter unit. The filtration efficiency of the filter plate 21 of the second filter unit is greater than that of the filter plate 21 of the first filter unit. The flow medium passes through the first filter unit and the second filter unit sequentially along the flow channel. Impurities in the flow medium are adsorbed and filtered by the filter plates 2121 of the first filter unit and the second filter unit, thereby achieving graded filtration of the flow medium and improving the purity of the flow medium.It is understood that in these two embodiments, the number of filter plates 21 in each filter unit is not limited according to the volume of the housing 10, the spacing between any two adjacent filter plates 21, and other requirements. Furthermore, it is understood that, based on the technical concept of achieving graded filtration, depending on the type of impurities, particle size, and other requirements, there can be a two-stage filtration method, a three-stage filtration method, or a filtration method with more than three stages. The number of filter units with different filtration efficiencies in the filter assembly 20 is not limited.

[0030] In one embodiment, the guide section 211 of the filter plate 21 located near the inlet 10a is aligned with the inlet 10a. The filter section 212 and guide section 211 of each filter plate 21 are arranged along the height direction of the housing 10, and the filter plates 21 are arranged along the length direction of the housing 10. Please refer to [link to relevant documentation]. Figure 1 Along the height direction of the box body 10 (e.g. Figure 1 The filter section 212 and the guide section 211 are arranged in the first direction of the chamber 10, and along the length direction of the chamber 10 (e.g., the first direction of the chamber 10). Figure 1 The filter plates 21 arranged in the second direction (in the middle) allow the entire filter assembly 20 to form a large filtration area and flow channels within a limited space. This further enhances the filtration capacity and extends the residence time of the fluid medium within the housing 10. Furthermore, the guide section 211 of the filter plate 21 positioned near the inlet 10a is aligned with the inlet 10a to prevent the fluid medium flowing in from the inlet 10a from directly impacting the filter section 212, thus avoiding damage to the filter section 212. Please refer to... Figure 4 Furthermore, the filter assembly 20 includes N filter plates 21, where N is an even number. The filter plates 21 are spaced apart to form (N-1) flow spaces 20a. Meanwhile, the outlet 10b and inlet 10a of the housing 10 are located on the same side of the housing 10. Thus, when the fluid medium flowing in the housing 10 passes the last filter plate 21, the fluid medium can flow downward along the height direction to the channel formed by the partition plate 11 and the inner wall of the housing 10. This channel extends along the length of the housing 10 to the outlet 10b of the housing 10. In this way, the length of the flow channel can be further extended, the contact area between the fluid medium and the housing 10 can be increased, thereby improving the heat exchange efficiency.

[0031] Please refer to one embodiment of this utility model. Figure 4The filter plate 21, positioned near the inlet 10a, is inclined and offset from the inlet 10a. The cross-section of the flow space 20a formed by the filter plate 21 and the side wall of the water tank gradually decreases from near the inlet 10a to away from the inlet 10a. Specifically, the inclined arrangement of the filter plate 21 allows the fluid medium to converge more quickly towards the filter section 212 under the action of gravity, accelerating the flow speed of the fluid medium near the inlet 10a. This allows the fluid medium at the inlet 10a to be guided to the filter section 212 in a short time. 2. To avoid the accumulation and retention of fluid medium at the inlet 10a, and to prevent excessive deposition of impurities near the inlet 10a, thereby ensuring the efficient start-up of the filtration process. At the same time, as the cross-section of the flow space 20a gradually decreases, the flow velocity of the fluid medium gradually increases as it moves away from the inlet 10a. This gives the impurity particles in the fluid medium higher kinetic energy before the filter section 212, which is more conducive to the collision and interception of impurity particles with the filter section 212, thereby improving the filtration efficiency and ensuring that more impurities can be effectively filtered out.

[0032] Furthermore, the water tank device also includes a pressurization chamber 20b. One end of the pressurization chamber 20b is connected to the filter holes of the filter plate 21 located away from the inlet 10a, and the other end of the pressurization chamber 20b is connected to the outlet 10b. For details, please refer to [link to relevant documentation]. Figure 4 The filter plate 21, which is located away from the inlet 10a, is inclined towards the inlet 10a. The bottom of the partition plate 11 is provided with a fixing plate extending along the height direction of the tank 10. The cross-section of the flow space 20a formed by the filter plate 21 and the side wall of the water tank gradually decreases from the direction near the inlet 10a to the direction away from the inlet 10a, so that the filter plate 21 and the inner side wall of the tank 10 form a converging flow space 20a. The fixing plate and the side wall of the water tank form a throat channel. The fixing plate, the partition plate 11, and the bottom wall of the tank 10 enclose and form an expanding flow space 20a. In this way, a pressurizing chamber 20b equivalent to a Venturi cavity can be formed in the tank 10, thereby realizing the pressurization of the fluid medium. Furthermore, a reinforcing rib is provided on the back of the fixing plate to effectively prevent the fixing plate from bending and deforming, thereby ensuring the pressurization effect.

[0033] In one embodiment of this utility model, at least a portion of the flow guiding section 211 and the filter section 212 are corrugated. The corrugated sections provide a larger surface area, significantly increasing the contact area between the fluid medium and the filter section 212 and the flow guiding section 211 during flow. This allows more heat from the fluid medium to be transferred to the surfaces of the filter section 212 and the flow guiding section 211, and then dissipated through the housing 10, effectively enhancing heat dissipation efficiency and reducing the temperature of the fluid medium. Simultaneously, as the fluid medium flows through the corrugated sections, its flow direction continuously changes, generating fluctuations. This change in flow state helps break the laminar boundary layer of the fluid medium, making it easier for heat to be transferred from the fluid interior to the surface in contact with the corrugated sections, accelerating heat dissipation and further improving the heat dissipation effect.

[0034] In one embodiment of this utility model, the flow guide section 211 and the filter section 212 of each filter plate 21 are detachably connected. In one embodiment, bolt holes are pre-drilled at corresponding positions on the two plates, and then bolts and nuts are used to connect the two plates. This connection method is simple to operate; simply pass the bolts through the bolt holes on the two plates and tighten the nuts to complete the connection. The detachable method facilitates the replacement of filter sections 212 that have accumulated a large amount of impurities due to long-term use, allowing for separate cleaning. At the same time, when the filter section 212 or the flow guide section 211 is damaged, it is not necessary to replace the entire filter plate 21; only the damaged or malfunctioning structure needs to be disassembled and replaced, effectively reducing replacement costs. In addition, the detachable connection method allows for flexible replacement of filter sections 212 with different filtration efficiencies according to actual usage needs. For example, when the size of impurity particles in the fluid medium changes, a filter section 212 suitable for that particle size can be quickly replaced to achieve the best filtration effect and meet the requirements of the therapeutic device for different water purity levels.

[0035] In another embodiment, please participate Figure 5 One of the flow guiding section 211 or the filter section 212 is provided with a fastening groove 21a, and the other of the flow guiding section 211 or the filter section 212 is provided with a fastening protrusion 213. The fastening protrusion 213 is inserted into the fastening groove 21a. Specifically, the end face of the filter plate 21 is provided with a fastening groove 21a extending in a third direction, and the end face of the flow guiding section 211 is provided with a fastening groove 21a and a fastening protrusion 213 extending in a third direction, which is the width direction of the housing 10. In this way, the flow guiding section 211 can be inserted into the filter section 212 by sliding and plugging, so that the two can be tightly connected and quickly disassembled.

[0036] Further, please refer to Figure 5The wall of the fastening groove 21a is provided with a first serrated protrusion 214, and the outer wall of the fastening protrusion 213 is provided with a second serrated protrusion 215 adapted to the first serrated protrusion 214. The first serrated protrusion 214 is staggered and inserted into the second serrated protrusion 215. After the flow guiding section 211 and the filter section 212 are connected, multiple sealing contact points will be formed between the fastening groove 21a and the fastening protrusion 213. These contact points can fit tightly and effectively block the leakage path of the fluid medium, thereby improving the sealing performance of the connection. At the same time, when the fastening protrusion 213 is inserted into the fastening groove 21a, the interaction force between the first serrated protrusion 214 and the second serrated protrusion 215 makes the contact pressure distribution between the two more uniform and forms a "biting and locking" effect at the connection, so that the filter plate 21 can maintain a stable sealing state when subjected to fluid medium pressure or other external forces, and is not prone to sealing failure due to vibration, pressure changes and other factors.

[0037] This utility model also proposes a therapeutic device, which includes a water system and a water tank device. The water system connects the inlet 10a and outlet 10b of the tank body 10. The therapeutic device can be an ultrasonic therapeutic device, a radiofrequency therapeutic device, a phototherapy device, an electrotherapy device, a magnetic therapy device, a microwave therapeutic device, etc. The specific type of the therapeutic device is not limited.
