Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, specifically to an electrolytic water device and a humidifier. Background Technology

[0002] Mist-free humidifiers use a fan to drive air through their internal humidification components to humidify the air. To ensure that the humidification components are adequately moistened, a circulating water supply is usually used to continuously supply water to the humidification components. However, the circulating water will wash away the dirt and impurities intercepted by the humidification screen into the water body. To prevent these impurities from causing odors and discoloration in the water over time, an electrolysis device is usually installed in the water body. However, there is a problem that the scale formed by electrolysis can easily block the water circulation path, thus failing to effectively wet the humidification components. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose an electrolytic water device, which has the advantages of good collection effect on scale formed by electrolysis and high reliability of humidification component of its humidifier.

[0005] An embodiment of this utility model also proposes a humidifier.

[0006] The electrolytic water device of this utility model embodiment includes an anode, a first cathode, and a scale collection box. The anode is used to be electrically connected to the positive terminal of the power supply, and the first cathode is used to be electrically connected to the negative terminal of the power supply. The scale collection box is provided with a scale collection cavity and a first water passage hole communicating with the scale collection cavity. The first cathode is at least partially disposed inside the scale collection cavity, and the anode is located outside the scale collection box.

[0007] According to the electrolytic water device of this utility model embodiment, by placing the first cathode inside the scale collection chamber of the scale collection box, when the first cathode and anode are connected to the circuit and located in the water body, the scale formed at the first cathode can be directly accumulated in the scale collection box, thereby achieving reliable scale collection. The scale collection box effectively reduces the probability of scale entering the circulating water circuit. Simultaneously, the scale collection box can be periodically removed for cleaning or replacement, effectively reducing the amount of scale flowing out of the scale collection box with the water flow through the first water passage, thereby further reducing the probability of scale clogging the circulating water circuit, and improving the reliability of the humidification component's immersion in the circulating water circuit.

[0008] In some embodiments, the water electrolysis device further includes an adapter for electrical connection to the negative terminal of the power source, the adapter being detachably electrically connected to the first cathode, the first cathode being electrically connected to the negative terminal of the power source via the adapter.

[0009] Therefore, the adapter can always maintain an electrical connection with the negative terminal of the power supply, and the electrical connection between the first cathode and the adapter ensures that the first cathode has the electrolysis function. Moreover, the adapter is also immersed in water during operation. When the scale collection box and the first cathode are removed and replaced with new scale collection box and first cathode, it is only necessary to electrically connect the first cathode to the adapter to integrate it into the circuit. The replacement efficiency of the scale collection box and the first cathode is high, and safety issues such as short circuits caused by integrating into the circuit are avoided.

[0010] In some embodiments, the outer wall of the scale collection box is provided with a first through hole communicating with the scale collection cavity. The first cathode includes a main body and a connecting part connected together. The main body is disposed in the scale collection cavity. A portion of the connecting part passes through the first through hole and is located outside the scale collection box. The portion of the connecting part located outside the scale collection box is detachably electrically connected to the adapter.

[0011] Therefore, by exposing the connection part of the first cathode outside the scale collection box, the electrical connection between the exposed connection part and the adapter is more intuitive when replacing the scale collection box and the first cathode, and the electrical connection between the two is convenient and reliable.

[0012] In some embodiments, the adapter is located outside the scale collection box, and the adapter includes a first spring and a second spring that abut against each other, with the portion of the connecting part outside the scale collection box inserted between the first spring and the second spring.

[0013] Therefore, the first cathode and the adapter are electrically connected by a plug-in connection, which makes disassembly and assembly simple and convenient, and the replacement efficiency of the scale collection box and the first cathode is high. Furthermore, when the connecting part is inserted between the first and second springs, at least one of the first and second springs undergoes elastic deformation to ensure that each of the first and second springs has a sufficiently large interaction force with the connecting part, thereby making the electrical connection between each of the first and second springs and the connecting part more reliable.

[0014] In some embodiments, the scale collection box includes a first lower shell and a first upper cover, the first upper cover being detachably connected to the first lower shell and forming the scale collection cavity, and the first water passage hole having a plurality of holes, all disposed on the first upper cover.

[0015] Therefore, by placing the first water passage hole on the first upper cover, the exchange of water inside the scale collection chamber with water outside the scale collection chamber is ensured, while also ensuring that the scale collection chamber is only open at the top. This results in a better scale collection effect, a lower probability of scale flowing out of the scale collection box through the first water passage hole, and a lower probability of scale clogging the humidifier's circulating water path.

[0016] In some embodiments, the edge of the main body is connected to the scale collection box, and the middle of the main body is suspended and provided with a plurality of first through holes.

[0017] Therefore, after the scale collection box is submerged in the water, the upper and lower surfaces of the main body, as well as the inner wall of the first through hole, are in contact with the water, effectively increasing the contact area between the water and the main body, thereby effectively improving the sterilization and disinfection efficiency of the water electrolysis device.

[0018] In some embodiments, the water electrolysis device further includes a second cathode and a voltage detection device. The second cathode is electrically connected to the negative terminal of the power supply, and the voltage detection device is connected in parallel with the second cathode to detect the voltage of the second cathode.

[0019] Therefore, as the TDS value of the water changes, the voltage of the second cathode also changes. By detecting the voltage of the second cathode through a voltage detection device, the TDS value of the water can be obtained. When the obtained TDS value reaches the preset value or preset range, it means that the water does not meet the usage requirements. In this case, the user will be reminded to change the water by means of light or sound to further reduce the chance of scale clogging the circulating water circuit.

[0020] In some embodiments, the water electrolysis device further includes a fixed box, the fixed box having a receiving cavity, the outer wall of the fixed box having a second water passage hole communicating with the receiving cavity, and the anode, the second cathode and the voltage detection device being disposed inside the receiving cavity.

[0021] Therefore, by concealing the anode, the second cathode, and the voltage detection device within the housing of the fixed box, the three components are effectively prevented from being exposed to the water storage space of the humidifier. When cleaning the water storage space, the probability of these three components being damaged by external impacts is effectively reduced, making the water electrolysis device more reliable.

[0022] In some embodiments, the water electrolysis device further includes a fixing box, the fixing box having a receiving cavity, the outer wall of the fixing box having a second water passage hole communicating with the receiving cavity, and the anode and the adapter being disposed within the receiving cavity; The outer wall of the fixing box is provided with a second through hole communicating with the receiving cavity. One of the adapter and the first cathode passes through the second through hole and is detachably electrically connected to the other of the adapter and the first cathode.

[0023] Therefore, by concealing the anode and adapter within the housing of the fixed box, both are effectively prevented from being exposed to the water storage space of the humidifier. This effectively reduces the chance of damage to both from external impacts when cleaning the water storage space, resulting in higher reliability of the water electrolysis device.

[0024] In some embodiments, the edge of the anode is connected to the fixing box, and the center of the anode is suspended and provided with a plurality of second through holes.

[0025] Therefore, after the fixed box is immersed in the water, the upper and lower surfaces of the anode, as well as the inner wall of the second through hole, are in contact with the water, effectively increasing the contact area between the water and the anode, and thus effectively improving the sterilization and disinfection efficiency of the water electrolysis device.

[0026] In some embodiments, the fixing box includes a second lower shell and a second upper cover, the second upper cover being detachably connected to the second lower shell and forming the receiving cavity, and the second water passage having a plurality of holes and being provided on at least one of the second upper cover and the second lower shell.

[0027] Therefore, by setting multiple second water passages, the contact area between the water inside and outside the receiving cavity is effectively increased, resulting in higher water exchange efficiency and thus higher sterilization and disinfection efficiency for the water in the storage cavity. The detachable connection between the second upper cover and the second lower shell facilitates the cleaning, maintenance, and replacement of the anode, adapter, second cathode, and voltage detection device within the receiving cavity.

[0028] The humidifier according to an embodiment of the present invention includes a water storage space and an electrolysis device as described in any of the above embodiments, wherein the anode is fixedly installed in the water storage space and the scale collection box is detachably disposed in the water storage space.

[0029] The technical advantages of the humidifier according to the present invention are the same as those of the electrolytic water device in the above embodiments, and will not be repeated here.

[0030] In some embodiments, the water electrolysis device further includes an adapter for electrical connection to the negative terminal of the power source, the adapter being fixedly installed within the water storage space, and the first cathode being detachably connected to the adapter.

[0031] Therefore, by fixing the anode and adapter to the water storage space, the electrical connection between the two and the circuit is guaranteed to be stable and reliable. When cleaning the water storage space, the anode and adapter are not easy to fall off, and the water electrolysis device is not easy to be damaged or fail.

[0032] In some embodiments, the water electrolysis device further includes a fixing box, which is fixedly installed in the water storage space, and the anode and the adapter are disposed in the fixing box.

[0033] This makes it easy to fix the anode and adapter in the water storage space, and the fixing box provides good protection for the anode and adapter, further reducing the chance of the anode 1 and adapter 7 being damaged by external impacts.

[0034] In some embodiments, the inner wall of the water storage space is provided with one of a guide groove and a guide rail, and the scale collection box is provided with the other of the guide groove and the guide rail. The scale collection box is slidably disposed in the water storage space through the cooperation of the guide groove and the guide rail.

[0035] Therefore, through the sliding fit of the guide groove and the guide rail, the first cathode can be moved accurately to the set position to achieve a more reliable electrical connection with the adapter.

[0036] In some embodiments, the guide groove is a dovetail groove or a T-groove; Alternatively, the guide groove is a U-shaped groove, and a limiting groove is provided on the side of the guide groove. The extending direction of the limiting groove is consistent with the extending direction of the guide groove. The guide rail has a protrusion on the opposite side along its width direction, and the protrusion slides in the limiting groove.

[0037] All of the above settings ensure that the scale collection box is relatively fixed in the vertical direction relative to the water storage space, making it less likely for the scale collection box to move relative to the fixed box, and ensuring high reliability of the electrical connection between the first cathode and the adapter.

[0038] In some embodiments, the humidifier includes a water tray and a water tank, at least one of which forms the water storage space. This achieves purification of the water in at least one of the water tray and the water tank and effective collection of limescale.

[0046] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] The following is combined Figures 1-7 Describes an electrolytic water apparatus 100 according to an embodiment of the present invention.

[0048] The electrolytic water device 100 of this embodiment includes an anode 1, a first cathode 2, and a scale collection box 3. The anode 1 is electrically connected to the positive terminal of a power supply, and the first cathode 2 is electrically connected to the negative terminal of the power supply. The scale collection box 3 has a scale collection cavity and a first water passage 321 communicating with the scale collection cavity. The first cathode 2 is at least partially disposed inside the scale collection cavity, and the anode 1 is located outside the scale collection box 3.

[0049] According to the electrolytic water device 100 of this utility model embodiment, by placing the first cathode 2 inside the scale collection chamber of the scale collection box 3, when the first cathode 2 and anode 1 are connected to the circuit and located in the water body, the scale formed at the first cathode 2 can be directly accumulated in the scale collection box 3, thereby achieving reliable scale collection. The scale collection box 3 effectively reduces the probability of scale entering the circulating water circuit. Simultaneously, the scale collection box 3 can be periodically removed for cleaning or replacement, effectively reducing the amount of scale flowing out of the scale collection box 3 through the first water passage 321 with the water flow, thereby further reducing the probability of scale clogging the circulating water circuit, and improving the reliability of the humidification component's immersion in the circulating water circuit.

[0050] It should be noted that the power source can be the battery inside the humidifier 200, or a power supply device electrically connected to the humidifier 200.

[0051] In some embodiments, such as Figure 3 and Figure 4 As shown, the water electrolysis device 100 also includes an adapter 7 for electrical connection to the negative terminal of the power supply. The adapter 7 is detachably electrically connected to the first cathode 2, and the first cathode 2 is electrically connected to the negative terminal of the power supply through the adapter 7.

[0052] At this time, the adapter 7 can always maintain an electrical connection with the negative terminal of the power supply. The electrical connection between the first cathode 2 and the adapter 7 ensures that the first cathode 2 has the function of electrolysis. Moreover, the adapter 7 is also immersed in the water during operation. When the scale collection box 3 and the first cathode 2 are removed and replaced with new scale collection box 3 and first cathode 2, it is only necessary to electrically connect the first cathode 2 to the adapter 7 to integrate it into the circuit. The replacement efficiency of scale collection box 3 and first cathode 2 is high, and safety problems such as short circuits caused by integrating into the circuit are avoided.

[0053] For example, the surface area of ​​the first cathode 2 is much larger than the surface area of ​​the adapter 7, and the first cathode 2 mainly functions as a water electrolyzer. The anode 1 is always electrically connected to the positive terminal of the power supply, and the adapter 7 is always electrically connected to the negative terminal of the power supply. The anode 1 and the adapter 7 are exposed in the water storage space 61 of the humidifier 200.

[0054] In some embodiments, the outer wall of the scale collection box 3 is provided with a first through hole communicating with the scale collection cavity. The first cathode 2 includes a main body 21 and a connecting part 22 connected together. The main body 21 is disposed in the scale collection cavity, and a part of the connecting part 22 passes through the first through hole and is located outside the scale collection box 3. The part of the connecting part 22 located outside the scale collection box 3 is detachably electrically connected to the adapter 7.

[0055] By exposing the connection part 22 of the first cathode 2 outside the scale collection box 3, the electrical connection between the exposed connection part 22 and the adapter 7 is more intuitive when replacing the scale collection box 3 and the first cathode 2, and the electrical connection between the two is convenient and reliable.

[0056] For example, such as Figure 5 As shown, the first cathode 2 is a metal sheet, the surface area of ​​its main body 21 is larger than the surface area of ​​the connecting part 22, the main body 21 is generally a square sheet, and the connecting part 22 is generally a strip sheet.

[0057] In some embodiments, the adapter 7 is located outside the scale collection box 3. The adapter 7 includes a first spring and a second spring that abut against each other, and the connecting part 22 is inserted between the first spring and the second spring.

[0058] That is, the first cathode 2 and the adapter 7 are electrically connected by a plug-in connection, which makes disassembly and assembly simple and convenient, and the replacement efficiency of the scale collection box 3 and the first cathode 2 is high. Moreover, when the connecting part 22 is inserted between the first spring and the second spring, at least one of the first spring and the second spring undergoes elastic deformation to ensure that there is a sufficiently large interaction force between each of the first spring and the second spring and the connecting part 22, thereby making the electrical connection between each of the first spring and the second spring and the connecting part 22 more reliable.

[0059] For example, the first and second springs are arranged in the vertical direction, and the ends of the first and second springs facing the scale collection box 3 are bent in opposite directions to form a V-shaped groove with the opening facing the scale collection box 3. The connecting part 22 moves in the horizontal direction and is inserted between the first and second springs through the V-shaped groove.

[0060] In some embodiments, such as Figure 3 and Figure 4 As shown, the scale collection box 3 includes a first lower shell 31 and a first upper cover 32. The first upper cover 32 is detachably connected to the first lower shell 31 and forms a scale collection cavity. There are multiple first water passage holes 321, all of which are provided on the first upper cover 32.

[0061] By placing the first water passage 321 on the first upper cover 32, the exchange of water in the scale collection chamber with water outside the scale collection chamber is ensured, while also ensuring that the scale collection chamber is only open at the top. This results in better scale collection, a lower probability of scale flowing out of the scale collection box 3 through the first water passage 321, and a lower probability of scale clogging the circulating water path of the humidifier 200.

[0062] For example, the first lower shell 31 forms a scale collection cavity with an open upper end, and the first upper cover 32 is detachably connected to the first lower shell 31 and seals the upper opening of the scale collection cavity. The first through hole can be provided on the side wall of the first lower shell 31, or it can be formed between the first lower shell 31 and the first upper cover 32.

[0063] For example, the first upper cover 32 is snapped into the first lower shell 31, or the first upper cover 32 and the first lower shell 31 are connected by a threaded part.

[0064] In some embodiments, such as Figure 3 and Figure 4 As shown, the edge of the main body 21 is connected to the scale collection box 3, and the middle part of the main body 21 is suspended and provided with a plurality of first through holes 211.

[0065] Therefore, after the scale collection box 3 is submerged in the water, the upper and lower surfaces of the main body 21, as well as the inner wall of the first through hole 211, are in contact with the water, effectively increasing the contact area between the water and the main body 21, thereby effectively improving the sterilization and disinfection efficiency of the water electrolysis device 100.

[0066] For example, the edge of the main body 21 is bonded or snapped to the scale collection box 3, and the main body 21 is located in the middle or lower part of the scale collection cavity in the vertical direction.

[0067] In some embodiments, the water electrolysis device 100 further includes a second cathode 4 and a voltage detection device. The second cathode 4 is electrically connected to the negative terminal of the power supply, and the voltage detection device is connected in parallel with the second cathode 4 to detect the voltage of the second cathode 4.

[0068] As the TDS (Total Dissolved Solids) value of the water changes, the voltage of the second cathode 4 also changes. By detecting the voltage of the second cathode 4 through a voltage detection device, the TDS value of the water can be obtained. When the obtained TDS value reaches the preset value or preset range, it means that the water does not meet the usage requirements. In this case, the user will be reminded to change the water by means of light or sound to further reduce the chance of scale clogging the circulating water circuit.

[0069] For example, the second cathode 4 is located outside the scale collection box 3, so its voltage corresponds to the TDS value of the water outside the scale collection box 3. This part of the water mainly supplies the circulating water circuit of the humidifier 200. If its TDS value is too high, it means that there is too much scale in this part of the water, which will make it easier to block the circulating water circuit.

[0070] It should be noted that the second cathode 4 is connected in parallel with the adapter 7, that is, the second cathode 4 and the adapter 7 are electrically connected to the negative terminal of the power supply through different wires.

[0071] In some embodiments, the water electrolysis device 100 further includes a fixing box 5, the fixing box 5 having a receiving cavity, the outer wall surface of the fixing box 5 having a second water passage hole 521 communicating with the receiving cavity, the anode 1 and the adapter 7 being disposed in the receiving cavity, the outer wall surface of the fixing box 5 having a second through hole communicating with the receiving cavity, one of the adapter 7 and the first cathode 2 passing through the second through hole and being detachably electrically connected to the other of the adapter 7 and the first cathode 2.

[0072] By concealing the anode 1 and the adapter 7 within the housing cavity of the fixed box 5, both are effectively prevented from being exposed to the water storage space 61 of the humidifier 200. When cleaning the water storage space 61, the probability of damage to both due to external impact is effectively reduced, making the water electrolysis device 100 more reliable.

[0073] For example, such as Figures 1-4 As shown, the fixing box 5 is fixedly installed in the water storage space 61 of the humidifier 200, thereby fixing the anode 1 and the adapter 7 in the set position of the water storage space 61 to ensure reliable electrical connection between the two and the positive and negative terminals of the power supply outside the water storage space 61. In addition, the receiving cavity of the fixing box 5 is divided into an outer cavity and an inner cavity. The anode 1 is located in the inner cavity, which communicates with the second water passage 521. The adapter 7 is located in the outer cavity, which communicates with the second water passage. The part of the connecting part 22 located outside the scale collection box 3 passes through the second water passage to be electrically connected to the adapter 7.

[0074] It should be noted that the second cathode 4 and the voltage detection device are also fixed in the receiving cavity of the fixed box 5, thereby reducing the probability of the second cathode 4 and the voltage detection device being damaged by external impacts, and making the water electrolysis device 100 more reliable.

[0075] In some embodiments, such as Figure 3 and Figure 4 As shown, the edge of the anode 1 is connected to the fixed box 5, and the middle part of the anode 1 is suspended and provided with multiple second through holes 11.

[0076] Therefore, after the fixed box 5 is immersed in the water, the upper and lower surfaces of the anode 1, as well as the inner wall of the second through hole 11, are in contact with the water, effectively increasing the contact area between the water and the anode 1, thereby effectively improving the sterilization and disinfection efficiency of the water electrolysis device 100.

[0077] For example, the anode 1 is a metal sheet structure, and the edge of the anode 1 is bonded or snapped to the fixing box 5. The anode 1 is located in the middle or lower part of the receiving cavity in the vertical direction.

[0078] In some embodiments, the fixing box 5 includes a second lower shell 51 and a second upper cover 52. The second upper cover 52 is detachably connected to the second lower shell 51 and forms a receiving cavity. There are multiple second water passage holes 521 and they are provided on at least one of the second upper cover 52 and the second lower shell 51.

[0079] By providing multiple second water passages 521, the contact area between the water inside and outside the containment cavity is effectively increased, resulting in higher water exchange efficiency and thus higher sterilization and disinfection efficiency for the water inside the containment cavity. The second upper cover 52 and the second lower shell 51 are detachably connected, facilitating the cleaning, maintenance, and replacement of the anode 1, adapter 7, second cathode 4, and voltage detection device inside the containment cavity.

[0080] For example, such as Figures 1-3 As shown, the second lower shell 51 is fixedly installed in the water storage space 61 of the humidifier 200. The second upper cover 52 is snapped onto the second lower shell 51 or connected by a threaded part. The second water passage hole 521 is provided on the second upper cover 52, or the second water passage hole 521 is provided on the side wall of the second upper cover 52 and the second lower shell 51.

[0081] like Figure 1 and Figure 2 As shown, the humidifier 200 according to an embodiment of the present invention includes a water storage space 61 and an electrolytic water device 100 as described in any of the above embodiments. The anode 1 is fixedly installed in the water storage space 61, and the scale collection box 3 is detachably disposed in the water storage space 61.

[0082] The technical advantages of the humidifier 200 according to the present utility model embodiment are the same as those of the electrolytic water device 100 in the above embodiment, and will not be repeated here.

[0083] It should be noted that the humidifier 200 includes a water tray 6 and a water tank, at least one of which forms a water storage space 61. Optionally, as Figure 2As shown, the water electrolysis device 100 is installed in the water storage space 61 enclosed by the water receiving tray 6.

[0084] In some embodiments, the water electrolysis device 100 further includes an adapter 7 for electrical connection to the negative terminal of a power source. The adapter 7 is fixedly installed in the water storage space 61, and the first cathode 2 is detachably connected to the adapter 7.

[0085] By fixing the anode 1 and the adapter 7 to the water storage space 61, the electrical connection between the two and the circuit is ensured to be stable and reliable. When cleaning the water storage space 61, the anode 1 and the adapter 7 are not easy to fall off, and the water electrolysis device 100 is not easy to be damaged or fail.

[0086] For example, the water electrolysis device 100 also includes a fixing box 5, which is fixedly installed in the water storage space 61, and the anode 1 and the adapter 7 are disposed in the fixing box 5.

[0087] This makes it easy to fix the anode 1 and the adapter 7 in the water storage space 61, and the fixing box 5 provides good protection for the anode 1 and the adapter 7, further reducing the probability of the anode 1 and the adapter 7 being damaged by external objects.

[0088] In some embodiments, the inner wall of the water storage space 61 is provided with one of a guide groove and a guide rail, and the scale collection box 3 is provided with the other of a guide groove and a guide rail. The scale collection box 3 is slidably disposed in the water storage space 61 through the cooperation of the guide groove and the guide rail.

[0089] The sliding fit between the guide groove and the guide rail facilitates the accurate movement of the first cathode 2 to the set position, so as to achieve a more reliable electrical connection with the adapter 7.

[0090] For example, the first cathode 2 and the adapter 7 are electrically connected by a plug-in fit. The insertion direction of the first cathode 2 is consistent with the extension direction of the guide rail. When the scale collection box 3 slides along the extension direction of the guide rail and abuts against the fixed box 5, the first cathode 2 and the adapter 7 are plugged into place, and the two are electrically connected.

[0091] In some embodiments, the guide groove is a dovetail groove or a T-groove. The outer contour of the guide rail matches the outer contour of the guide groove. The cooperation between the two ensures that the scale collection box 3 is relatively fixed in the vertical direction relative to the water storage space 61, making it less likely for the scale collection box 3 to move relative to the fixed box 5, and ensuring high reliability of the electrical connection between the first cathode 2 and the adapter 7.

[0092] Optionally, the guide groove is a U-shaped groove, and a limiting groove is provided on the side of the guide groove. The extension direction of the limiting groove is consistent with the extension direction of the guide groove. The guide rail has a protrusion on the opposite side along its width direction, and the protrusion slides in the limiting groove.

[0093] The cooperation between the protrusion and the limiting groove also achieves the relative fixation of the scale collection box 3 relative to the water storage space 61 in the vertical direction, making it less likely for the scale collection box 3 to move relative to the fixed box 5, and ensuring high reliability of the electrical connection between the first cathode 2 and the adapter 7.
