Description

Technical Field

[0001] This application belongs to the field of electronic atomization equipment technology, and in particular relates to an electronic atomization device, an atomizer and its suction resistance adjustment mechanism. Background Technology

[0002] The variety of electronic atomization devices on the market is constantly increasing, and consumers' expectations for product performance are also continuously rising. In practical usage scenarios, due to individual differences in consumers' preferences for inhalation resistance, and the need to match different output powers with corresponding airflow volumes, mainstream electronic atomization devices are generally equipped with inhalation resistance adjustment mechanisms to meet users' personalized needs.

[0003] Currently, suction resistance adjustment mechanisms in the industry mainly fall into two categories: one uses a linear slide rail mechanism, which adjusts airflow by pushing a slider to make linear displacement movements; the other uses a rotary adjustment mechanism, which changes the intake volume by rotating a knob. However, existing suction resistance adjustment mechanisms generally suffer from problems such as simple structure, lack of gear positioning, and lack of operational feedback, which to some extent affects the user's operating experience. Utility Model Content

[0004] The purpose of this application is to provide an electronic atomizing device, an atomizer, and its draw resistance adjustment mechanism to solve the technical problem that the draw resistance adjustment mechanism on existing atomizers lacks gear positioning and operation feedback.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, embodiments of this application provide a suction resistance adjustment mechanism for an atomizer, wherein the atomizer is provided with an air passage communicating with the outside world, and the air passage has a flow-limiting hole; The suction resistance adjustment mechanism includes a knob and a ring body that are nested together. The ring body has a plurality of gear slots. The knob has a turntable and a protrusion for engaging with the gear slots. The turntable has an air passage hole for aligning with the flow-limiting hole. The knob is operated by a person to drive the turntable to rotate, and simultaneously causes the protrusion to stop in the corresponding gear slot.

[0006] Therefore, when a person operates the knob, it drives the turntable to rotate, aligning the air vent on the turntable with the flow-limiting orifice in the air passage. This adjusts the opening size of the flow-limiting orifice, thereby regulating the suction resistance. Simultaneously, the protrusion on the knob will lock into the corresponding position slot as the turntable rotates, locking the intersecting position of the air vent and the flow-limiting orifice, thus achieving gear positioning and providing the user with clear tactile feedback.

[0007] The structure of the knob is improved by adding a pair of symmetrically arranged protrusions that synchronously engage with symmetrically positioned gear slots on the ring body. This enhances the stability of the gear setting, prevents accidental triggering, and effectively ensures the stability of the resistance gear adjustment.

[0008] In one embodiment, the knob has a spring plate, and the protrusion is disposed on the end face of the spring plate facing the ring body. The spring plate elastically deforms to engage the protrusion with the gear slot. Thus, the spring plate with the protrusion on the knob and the gear slot on the ring body form an elastic engagement structure, utilizing the natural rebound force of the spring plate to press the protrusion firmly into the gear slot. When rotating the knob, the spring force must be overcome to change gears, making the tactile feedback more pronounced.

[0009] In one embodiment, both the flow-limiting orifice in the air passage and the air passage on the turntable are oblong orifices. This facilitates adaptation to the rotational movement of the knob and effectively ensures the accuracy of suction resistance adjustment.

[0010] In one embodiment, the knob is further provided with a slider, and the ring body is provided with a limiting groove for the slider to be inserted and slid. The limiting groove is used to limit the movement range of the knob. In this way, the rotation range of the knob is limited, preventing excessive rotation from causing misalignment and failure of the internal vent hole and the limiting hole.

[0011] Secondly, this application also provides an atomizer, including the aforementioned draw resistance adjustment mechanism. The atomizer contains an atomizing core and a support, with the atomizing core mounted on the support. The atomizer has an air vent communicating with the outside. Both ends of the air passage are connected to the air vent and the inner cavity of the support, respectively, and communicate with the atomizing core through the inner cavity of the support. The bottom of the atomizer also has a mounting hole for mounting the knob. A ring is formed in the mounting hole, and a protrusion on the knob can move on the ring or be engaged in a slot on the ring. This allows the user to operate the knob to rotate a turntable, causing the air passage on the turntable to align with the flow-limiting orifice in the air passage, thereby changing the conduction range of the flow-limiting orifice and achieving flexible adjustment of the draw resistance. The knob is set in the mounting hole of the base and cooperates with the ring. As the knob is operated and rotated, the protrusion on the knob can move along the inner wall of the ring and stop in the gear slot of the ring, thereby realizing gear positioning and providing tactile feedback to the user.

[0012] In one embodiment, the bracket has a protrusion extending towards the knob, and the back of the protrusion has a slot on the bracket. The air passage is inserted into the slot, and the flow-limiting hole is formed on the protrusion and communicates with the air passage. The knob also has a rotating shaft, and a turntable is mounted on the rotating shaft and abuts against the protrusion, so that the air passage on the turntable is parallel and aligned with the flow-limiting hole on the protrusion. This facilitates, on the one hand, that when the upper shell and base are assembled, the air passage can automatically insert into the slot of the bracket and accurately align with the flow-limiting hole on the protrusion, allowing for rapid air passage connection and improving assembly efficiency. On the other hand, when the knob is manually rotated, the air passage on the turntable and the flow-limiting hole on the protrusion will always remain parallel and aligned, which is beneficial for adjusting the opening size of the flow-limiting hole and ensures smooth knob rotation.

[0013] In one embodiment, an air passage gap is formed between the turntable and the ring. This allows external air to enter through the air vent, flow into the inner cavity of the support through the air passage and flow restriction hole, and then flow to the atomizing core through the air passage gap between the turntable and the ring, effectively ensuring the unobstructed flow of the air exchange channel.

[0014] In one embodiment, the outer periphery of the knob is further provided with a sealing ring and a groove for mounting the sealing ring, the outer periphery of the sealing ring abutting against the inner wall of the ring body. This creates a dynamic sealing interface between the sealing ring and the inner wall of the ring body, preventing external air from entering the atomizer through the mounting hole, thus improving airtightness and effectively ensuring that the airflow entering the atomizer is regulated through the flow-limiting orifice, thereby improving the reliability of the draw resistance adjustment.

[0015] Thirdly, embodiments of this application also provide an electronic atomizing device, including a body, a power supply component, and an atomizer, wherein the atomizer is detachably connected to the body; the power supply component is disposed within the body, and includes a circuit board and a battery for supplying power to the atomizer; the atomizing core in the atomizer includes at least a heating element, which is electrically connected to the circuit board. This allows the atomizer to be used as a replaceable part; when the liquid in the reservoir is depleted, the atomizer can be removed from the body and replaced with a new one, effectively achieving rapid battery life.

[0016] The beneficial effects of the electronic atomizing device, atomizer, and its draw resistance adjustment mechanism provided in this application are as follows: Compared with the prior art, the draw resistance adjustment mechanism of this application utilizes the alignment and cooperation between the air passage hole on the knob's turntable and the flow-limiting hole in the airway to achieve linear adjustment of the airflow channel area, thereby precisely controlling the draw resistance and facilitating adaptation to different power levels or user preferences. Simultaneously, the protrusion on the knob engages with the various position slots on the ring, discretizing the rotation angle into fixed positions. This ensures that the relative positions of the air passage hole and the flow-limiting hole are fixed after each adjustment, providing a clear "position feel" when the knob is rotated, thus offering precise adjustment feedback. Furthermore, because there is an angular gap between adjacent position slots, a certain torque is required to push the knob, which helps prevent accidental rotation during daily carrying or holding, avoiding unexpected changes in airflow due to accidental touch or vibration, and effectively ensuring the stability of the draw resistance adjustment.

Detailed Implementation

[0020] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0021] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0022] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] Traditional atomizers employ two main types of draw resistance adjustment mechanisms: a linear guide mechanism, which adjusts airflow by pushing a slider in a linear motion; and a rotary adjustment mechanism, which changes the airflow volume through the circular motion of a knob. Rotary adjustment mechanisms, in particular, fall into two main categories: one where the knob is located at the bottom of the atomizer, directly adjusting the opening of the bottom airflow port when rotated. This design requires removing the atomizer or inverting the device for adjustment, making it slightly inconvenient. The other type places the knob on the side of the atomizer, controlling the airflow volume by rotating a side adjustment ring. This design is slightly more complex and may increase the atomizer diameter. As can be seen, both of these draw resistance adjustment mechanisms generally suffer from simplistic structures, lack of feedback on the adjustment levels, and vague tactile feedback, which negatively impact the user experience.

[0025] Therefore, this application provides a novel draw resistance adjustment mechanism, atomizer, and electronic atomizing device. The draw resistance adjustment mechanism on the atomizer is improved, featuring multiple levels and tactile feedback, enhancing the user's operating experience and effectively solving the problem of traditional draw resistance adjustment mechanisms on atomizers lacking level positioning and operational feedback. A detailed description is now provided.

[0026] Please refer to the following: Figure 1 and Figure 2 An atomizer is provided with an air passage 1 that communicates with the outside world, and the air passage has a flow restrictor 10.

[0027] The atomizer has a draw resistance adjustment mechanism provided in the embodiments of this application, the draw resistance adjustment mechanism including a knob 2 and a ring 3 for mounting the knob 2.

[0028] The ring body 3 is provided with a plurality of stop grooves 31. In this embodiment, a plurality of stop grooves 31 are provided on the inner wall of the ring body 3, and adjacent stop grooves 31 are spaced apart.

[0029] The knob 2 has a handle 20 and is fitted onto the ring 3. In this embodiment, the knob 2 is preferably fitted inside the ring 3. The knob 2 is provided with a turntable 21 and protrusions 22 for engaging with each gear slot 31 respectively.

[0030] The turntable 21 has an air passage 211 that matches the shape of the flow-limiting hole 10 in the air passage 1. The air passage 211 is used to align with the flow-limiting hole 10. In this embodiment, the turntable 21 is integrally formed on the knob 2. When the knob 2 is operated by hand, it will simultaneously drive the turntable 21 to rotate and cause the protrusion 22 to stop in the corresponding position slot 31.

[0031] In other embodiments (not shown in the figure), the turntable 21 can also be detachably mounted on the knob 2, which facilitates the replacement of the turntable 21 with different shaped air passages 211 (single hole or multi-hole array), thereby improving the adaptability to more airflow characteristic requirements.

[0032] In actual operation, when the knob 2 is rotated by hand, it drives the turntable 21 to rotate, causing the air passage 211 on the turntable 21 to align with the flow-limiting hole 10 of the air passage 1, thereby adjusting the opening size of the flow-limiting hole 10 and adjusting the suction resistance. For example, when the air passage 211 and the flow-limiting hole 10 are fully aligned, the air passage 1 is completely unobstructed, which helps to reduce suction resistance. When the air passage 211 and the flow-limiting hole 10 are misaligned, the air passage area in the air passage 1 will be reduced with the degree of misalignment, thereby increasing the suction resistance. During this process, the protrusion 22 on the knob 2 will stop in the corresponding position of the gear slot 31 as the turntable 21 rotates. When the protrusion 22 stops in the gear slot 31, it can lock the misalignment position of the air passage 211 and the limit hole, realize gear positioning, and provide the user with clear tactile feedback.

[0033] Compared with the prior art, the suction resistance adjustment mechanism on the atomizer provided in this application embodiment utilizes the air passage 211 on the turntable 21 of the knob 2 to align with the flow limiting hole 10 in the air passage 1 to achieve linear adjustment of the airflow passage area, thereby precisely controlling the suction resistance and facilitating adaptation to different power levels or user preferences.

[0034] Meanwhile, the protrusion 22 on the knob 2 engages with the various position slots 31 on the ring 3, discretizing the rotation angle into fixed positions. This ensures that the relative positions of the air passage 211 and the flow restriction hole 10 are fixed after each adjustment, giving the knob 2 a clear "position feel" when rotating, thus providing clear adjustment feedback. Furthermore, because there is an angular gap between adjacent position slots 31, a certain torque is required to push the knob 2. This helps prevent accidental rotation during daily carrying or holding, avoiding unexpected changes in airflow due to accidental touch or vibration, and effectively ensuring the stability of the suction resistance adjustment.

[0035] In addition, when the protrusion 22 on the knob 2 engages with the gear slot 31 of the ring 3, it produces a sound similar to "click" and a tactile feedback, allowing the user to perceive the gear shift without visual inspection, thereby improving the intuitiveness of operation and enhancing the user experience.

[0036] For the structure of knob 2, please refer to one embodiment of this application. Figure 3 and Figure 4 The knob 2 is provided with a pair of symmetrically arranged protrusions 22, which are synchronously locked on the gear slots 31 on the ring body 3.

[0037] In this embodiment, as Figure 4 As shown, the inner wall of the ring 3 has five pairs of symmetrically arranged gear slots 31 relative to the center, and each pair of gear slots 31 is set to one gear position. As an example, the five pairs of gear slots 31 can be configured to include one off position and four working positions. When the knob 2 is rotated to adjust the air pressure, each time it is rotated to a gear position, a pair of protrusions 22 will engage with the corresponding pair of gear slots 31, producing a noticeable damping sensation.

[0038] In this way, the pair of protrusions 22 on the knob 2 respectively engage with the symmetrically arranged gear slots 31 on the ring 3 to achieve gear positioning, which helps to improve the fixing strength of the gear, prevent false triggering, and effectively ensure the stability of the suction resistance gear adjustment.

[0039] In one embodiment of this application, please refer to Figure 3 The knob 2 has a spring piece 23, and a protrusion 22 is provided on the end face of the spring piece 23 facing the ring body 3. The spring piece 23 undergoes elastic deformation to make the protrusion 22 engage with the gear slot 31.

[0040] In this embodiment, the knob 2 has a pair of symmetrically arranged spring pieces 23, and each spring piece 23 has the aforementioned protrusion 22 on its outer surface. As the knob 2 is operated and rotated, the protrusions 22 on the pair of spring pieces 23 can be synchronously locked in a pair of corresponding gear slots 31 to achieve gear positioning.

[0041] Therefore, a spring piece 23 with a protrusion 22 is provided on the knob 2 to form an elastic engagement structure with the gear slot 31 on the ring body 3. The natural rebound force of the spring piece 23 can press the protrusion 22 into the gear slot 31. When the knob 2 is rotated, the spring force needs to be overcome to switch gears, which helps to produce a clear "step" and "click" sound, making the feedback of operation more obvious.

[0042] Furthermore, the continuous clamping force of the spring piece 23 prevents the knob 2 from rotating due to equipment vibration or accidental collision, effectively avoiding unexpected changes in suction resistance and thus improving the reliability of gear positioning. Compared with the structure of a rigid protrusion 22 on a conventional knob 2, the elastic contact of the spring piece 23 in this embodiment can buffer mechanical impact, reduce hard friction between the gear slot 31 and the protrusion 22, and help extend service life.

[0043] Preferably, such as Figure 3 As shown, the two sides of the protrusion 22 can preferably have chamfers. The chamfered part on the protrusion 22 forms a guide surface 221. Combined with the elastic deformation capability of the spring piece 23, the protrusion 22 can slide slightly in the gear slot 31. This helps to ensure that even if there are manufacturing tolerances or wear, it can still maintain a stable engagement and further ensure the reliability of gear positioning.

[0044] Please refer to the embodiments in this application as well. Figure 2 and Figure 3 The flow-limiting hole 10 in the airway 1 and the air passage hole 211 on the turntable 21 are both waist-shaped holes.

[0045] In this embodiment, the intake area varies depending on the state of the five gear positions, such as... Figure 5 , Figure 6 and Figure 7 As shown, there are three working positions with different suction resistance levels, and the overlap between the flow restrictor 10 and the air passage 211 changes accordingly; Figure 8 As shown, this is the working position where the flow-limiting orifice 10 and the air passage 211 completely overlap, and the flow-limiting orifice 10 is fully open; as Figure 9 As shown, this is the closed position where the flow restrictor 10 is completely blocked by the turntable 21.

[0046] In other embodiments (not shown in the figure), multiple waist-shaped air passages 211 can be opened on the turntable 21. Each air passage 211 is matched with the position of the gear slot 31 and is aligned with the waist-shaped limiting hole. As the number of air passages 211 is opened, the opening becomes larger, or the air passage 1 is closed when each air passage 211 is blocked.

[0047] In this way, the waist-shaped limiting hole and the air passage 211 work together to adapt to the rotational movement of the knob 2, effectively ensuring the adjustment accuracy of the suction resistance, thereby improving the reliability of gear positioning and user experience.

[0048] For the mating structure between the knob 2 and the ring 3, please refer to one embodiment of this application. Figure 3 and Figure 10 The knob 2 is also equipped with a slider 24, and the ring 3 is equipped with a limiting groove 32 for the slider 24 to be inserted and slide, thereby limiting the movement of the knob 2.

[0049] In this embodiment, as Figure 10 As shown, a semi-circular groove 32 is provided on the inner wall of the ring 3, and both ends of the groove 32 have protruding stop portions 321. Correspondingly, a slider 24 is provided on the knob 2 to engage with the groove 32, and the slider 24 can be embedded in the groove 32. As the knob 2 rotates in the ring 3, the slider 24 slides along the groove 32 until it abuts against the stop portion 321 at either end of the groove 32.

[0050] This limits the rotation range of knob 2, preventing excessive rotation from causing misalignment and failure of the internal vent 211 and the limiting hole. It also helps to precisely control the movement between the maximum suction resistance position and the off position, extending the lifespan of knob 2. In actual operation, when knob 2 reaches its limit position, the collision between slider 24 and the stop parts 321 at both ends of the limiting groove 32 produces a noticeable jolt, coupled with the "click" sound produced when the protrusion 22 engages with the gear slot 31. This helps to indicate to the user that the adjustment boundary has been reached, thus preventing the user from blindly rotating the knob to find the gear and effectively improving operational efficiency.

[0051] In one embodiment of this application, please refer to the following: Figure 1 and Figure 11 The atomizer 100 in this embodiment of the application also includes an upper shell 4, a base 5, a mouthpiece 6, an atomizing core 7, and a bracket 8. The upper shell 4 and the base 5 are connected to form the atomizer 100.

[0052] The support 8 is mounted on the base 5, and the support 8 encloses the upper shell 4 to form a liquid storage chamber 101. This can be understood as having an internal space between the inner cavity of the upper shell 4 and the support 8, surrounding the atomizing core 7, which can be used as a liquid storage chamber 101 for loading the aerosol matrix.

[0053] The atomizing core 7 is mounted on the support 8, and the nozzle 6 is mounted on the upper shell 4 and extends into the upper shell 4 to communicate with the atomizing core 7. The atomizing core 7 is used to heat the aerosol matrix in the liquid storage tank 101 to generate aerosol that is output from the nozzle 6.

[0054] The air passage 1 on the atomizer 100 is formed inside the upper shell 4. The upper shell 4 has an air exchange port 41 that communicates with the outside. One end of the air passage 1 is connected to the air exchange port 41, and the other end of the air passage 1 is connected to the bracket 8, so as to communicate with the inner cavity of the bracket 8 through the flow-limiting hole 10, and with the atomizing core 7 through the inner cavity of the bracket 8. In this embodiment, as... Figure 11 As shown (the arrows in the figure indicate the ventilation path), the air exchange port 41, the airway 1, the inner cavity of the bracket 8, the atomizing core 7, and the mouthpiece 6 are connected in sequence to form an air exchange channel.

[0055] The base 5 has a mounting hole 51 located at the bottom of the atomizer 100 for mounting the knob 2. The ring body 3 is preferably integrally formed on the mounting hole 51 of the base 5. The protrusion 22 on the knob 2 can move on the ring body 3 or be locked in the gear slot 31 on the ring body 3.

[0056] In this way, the user operates the knob 2 to drive the turntable 21 on the knob 2 to rotate, so that the air passage 211 on the turntable 21 aligns with the flow restriction hole 10 in the air passage 1, thereby changing the conduction range of the flow restriction hole 10, realizing flexible adjustment of suction resistance, and improving user experience. The knob 2 is set in the mounting hole 51 of the base 5 and cooperates with the ring 3. As the knob 2 is operated and rotated, the protrusion 22 on the knob 2 can move along the inner wall of the ring 3 and stop on the gear slot 31 of the ring 3, thereby realizing gear positioning and providing tactile feedback to the user.

[0057] For the structure on bracket 8, please refer to one embodiment of this application. Figure 11 , Figure 12 and Figure 13 The bracket 8 has a protrusion 81 that protrudes towards the knob 2, and the back of the protrusion 81 has a slot 82 located on the bracket 8. The air passage 1 is inserted into the slot 82 of the bracket 8, and the flow-limiting hole 10 is opened on the protrusion 81 and communicates with the air passage 1.

[0058] In this embodiment, the protrusion 81 on the bracket 8 protrudes towards the knob 2, so that the end face of the bracket 8 connected to the air passage 1 has a slot 82 located on the back of the protrusion 81, allowing one end of the air passage 1 to be inserted into the slot 82, and the other end to be connected to the air exchange port 41 on the upper shell 4. This facilitates the automatic insertion of the air passage 1 into the slot 82 of the bracket 8 and accurate alignment with the flow-limiting hole 10 on the protrusion 81 when the upper shell 4 and the base 5 are assembled together, enabling the air passage to quickly complete the docking and improving assembly efficiency.

[0059] Please refer to the following: Figure 11 , Figure 12 and Figure 13The convex bulge 81 is provided with a shaft hole 811, which is preferably disposed to avoid the flow-limiting hole 10 on the convex bulge 81. The knob 2 is also provided with a rotating shaft 25, which is inserted into the shaft hole 811 of the convex bulge 81. The turntable 21 is disposed on the rotating shaft 25 and abuts against the convex bulge 81, so that the air passage 211 on the turntable 21 can be aligned parallel to the flow-limiting hole 10 on the convex bulge 81.

[0060] When the knob 2 is rotated manually, the air passage 211 on the turntable 21 and the flow restriction hole 10 on the protrusion 81 will always remain parallel and aligned. This is beneficial for adjusting the opening size of the flow restriction hole 10 and also ensures the smooth rotation of the knob 2, thus improving the user experience.

[0061] Preferably, in one embodiment of this application, please refer to Figure 11 The rotating shaft 25 on knob 2 raises the turntable 21 until it rests against the protrusion 81. The turntable 21 is raised higher than the ring 3, creating an air passage gap M between the turntable 21 and the ring 3. This allows external air to enter through the air vent 41, flow through the air passage 1 and the flow restrictor 10 into the inner cavity of the bracket 8, and then flow through the air passage gap M between the turntable 21 and the ring 3 to the atomizing core 7, effectively ensuring the unobstructed flow of air.

[0062] Regarding the mounting hole 51 of the knob 2 on the base 5, and the mating structure between the knob 2 and the ring 3, please refer to one embodiment of this application. Figure 11 and Figure 14 The knob 2 is also provided with a sealing ring 26 and a groove 261 for installing the sealing ring 26 on its outer periphery. The sealing ring 26 can preferably be made of silicone material, and the outer periphery of the sealing ring 26 abuts against the inner wall of the ring body 3.

[0063] In this way, the sealing ring 26 and the inner wall of the ring body 3 form a dynamic sealing interface, preventing external air from entering the atomizer through the mounting hole 51. This helps to improve air tightness and effectively ensures that the airflow entering the atomizer is regulated through the flow limiting hole 10, thereby improving the reliability of the suction resistance adjustment.

[0064] Please refer to the following: Figure 15 and Figure 16 This application also provides an electronic atomizing device, including a body 200 of the electronic atomizing device, a power supply component 9, and the atomizer 100 provided in the above-mentioned embodiment of this application. The atomizer 100 can be used as a replacement part and can be detachably connected to the body 200.
