Description

Technology Field

[0001] The present invention relates to a display mounting device for a water purifier, and more specifically, to a display mounting device for a water purifier that allows the display to be separated from the main body of the water purifier and rotated and angle-adjusted, thereby enabling the user to easily check water quality data and control screens not only from the front of the water purifier but also from the side and non-front positions. Background Technology

[0002] Laboratory pure and ultrapure water production units are essential equipment used in various research fields such as life sciences, chemistry, and pharmacy. They produce ultrapure water using reverse osmosis (RO) filters and provide information such as water quality data (resistivity, TOC, etc.) and filter replacement notifications via a display.

[0003] Most conventional laboratory water purifiers adopt a structure in which the display is embedded in the front of the main body or attached at a fixed angle.

[0004] While such fixed displays allow for easy information verification when the user is positioned in front of the water purifier, there is a problem where visibility is significantly reduced when the water purifier is placed in a corner, on an upper shelf, or in a lower space due to space constraints in the laboratory.

[0005] In particular, laboratory environments are often very cramped due to various analytical equipment and reagents, so users frequently perform dispensing tasks from the side of the water purifier or in a non-frontal position.

[0006] At this time, it is difficult to check water quality or water volume in real time with a fixed display, which reduces work efficiency and hinders the accurate conduct of experiments.

[0007] In addition, laboratory water purifiers are often used by moving the water collection gun away from the main body to collect water in beakers or large-capacity carboys; in this case, if the display, which serves as the control device, is fixed to the main body, a mismatch occurs between the collection location and the control location.

[0008] This causes inconvenience for users who must repeatedly move and check the main unit and the water collection location, and leads to a decrease in experimental accuracy due to missed real-time monitoring.

[0009] Therefore, there is a need to develop a display mounting device for water purifiers that allows users to adjust the display to the optimal angle and distance from any position, in response to various spatial layouts and working environments in laboratories. Prior art literature

[0010] Published Patent Application No. 10-2021-0085640 The problem to be solved

[0011] The objective of the present invention is to meet the technical challenges described above by providing a display mounting device for a water purifier that allows the user to easily check water quality data and control screens not only from the front of the water purifier but also from side and non-front positions by separating the display from the main body of the water purifier to enable rotation and angle adjustment.

[0012] Another objective of the present invention is to provide a display mounting device for a water purifier that can secure an optimal viewing angle even in confined spaces of a laboratory and various placement environments by implementing free angle adjustment in multiple axial directions through a three-stage rotation structure of a base module, a rotating module, and a tilting module. means of solving the problem

[0013] As a means to achieve the above objective, the configuration of the present invention may include: a base module that is fixed to the front of the water purifier body, is coupled to the base module, is positioned between a water purifier body equipped with a dispenser and a display separated from the water purifier body and controlling the operation of the water purifier body, and supports the display, and is configured to selectively vary the position of the front direction of the display through rotation and angle adjustment; a rotating module coupled to the base module and rotatably positioned along the circumferential direction on the front of the base module; and a pair of tilting modules, one part of which is coupled to the rear of the display and the other part of which is coupled to both sides of the rotating module, and rotatably positioned along the circumferential direction on the sides of the rotating module.

[0014] The configuration of the present invention may include: a base body coupled to the front of the water purifier body and having a central portion protruding forward; a rotating guide groove recessed in the center of the base body and supporting the outer surface of the rotating module inserted therein to guide the rotation of the rotating module; and a rotating guide projection protruding from the center of the rotating guide groove and inserted into the rotating module inserted into the rotating guide groove to support the inner surface of the rotating module.

[0015] The configuration of the present invention may include: a rotating module comprising: a rotating body in the shape of a flat plate; a rotating sleeve protruding from the rear surface of the rotating body and inserted into the rotating guide groove, wherein the outer surface is supported by the rotating guide groove and the inner surface is supported by the rotating guide projection, and is rotatably arranged along the circumferential direction; a pair of tilting guide sleeves disposed at both ends of the rotating body and supporting the outer surface of the pair of tilting modules inserted into them to guide the rotation of the pair of tilting modules; and a pair of tilting guide projections protruding from the center of the pair of tilting guide sleeves and inserted into the interior of the pair of tilting modules inserted into the pair of tilting guide sleeves to support the inner surface of the pair of tilting modules.

[0016] The configuration of the present invention may include, wherein each of the pair of tilting modules comprises: a flat-shaped fixing tab coupled to the rear surface of the display and fixed to the display; a tilting body extending from the fixing tab and arranged coaxially with the tilting guide sleeve; and a tilting sleeve protruding from the inner surface of the tilting body, inserted into the tilting guide sleeve, with its outer surface supported by the tilting guide sleeve and its inner surface supported by the tilting guide projection, and arranged to be rotatable along the circumferential direction.

[0017] The configuration of the present invention comprises: a first arm member extending from the rotating body and having a receiving space inside; a second arm member inserted into the interior of the first arm member and coupled to be slidably movable in the longitudinal direction; and a length adjustment locking unit provided between the first arm member and the second arm member to fix the extension length of the second arm member; wherein at least one of the first arm member and the second arm member may be configured to have a hinge joint formed at an intermediate point in the longitudinal direction to adjust the separation distance and bending angle of the display in multiple stages.

[0018] The configuration of the present invention is such that a guide rail is formed recessed along the longitudinal direction on the outer surface of the second arm member, and a guide rib corresponding to the guide rail is formed on the inner surface of the first arm member, so that when the second arm member is withdrawn, circumferential rotation is constrained by the combination of the guide rail and the guide rib, while only longitudinal movement is guided, and a friction coating layer may be formed on the surface of the guide rail.

[0019] The configuration of the present invention may further include a torsion spring disposed between the tilting sleeve and the tilting guide projection, having one end fixed to the side of the tilting sleeve and the other end fixed to the side of the tilting guide projection, which elastically deforms when the tilting sleeve is rotated and then returns to its original state by elastic force when the external force applied to the tilting sleeve is removed, thereby returning the tilting sleeve to its original angular position.

[0020] The configuration of the present invention may include: a base plate coupled to the rear of the display for the fixed tab; a support plate disposed at the end of the tilting body and positioned opposite the base plate; and an elastic cushioning member made of an elastic material disposed between the base plate and the support plate, which absorbs shock by causing elastic deformation in response to impact applied from the front and side directions of the base plate.

[0021] The configuration of the present invention may include: a fastening slot formed on the rear surface of the base body and slidably coupled from top to bottom to a hook-shaped mounting bracket formed on the front surface of the water purifier body; a locking lever, a portion of which is rotatably coupled to the base body and another portion of which is received in a storage groove formed inside the base body and communicating with the fastening slot; and a locking block received in the storage groove, which, when the locking lever is rotated, is pressed against the locking lever and protrudes toward the fastening slot side, thereby pressing and fixing the mounting bracket coupled to the fastening slot.

[0022] The configuration of the present invention may include: a support block that supports the display by being formed in a tapered shape that protrudes from the front of the base plate and becomes narrower as it goes downward, and is coupled to a tapered coupling groove formed on the rear of the display; an elastic member coupled to the upper end of the support block; a locking member coupled to the upper end of the elastic member and supported by being caught in a locking groove formed on the upper part of the coupling groove; and detachable magnets installed on the front of the base plate, positioned on the upper and lower parts of the support block, and detachably coupled to fixed magnets embedded in the rear of the display through magnetic force. Effects of the invention

[0023] According to the present invention, by separating the display from the main body of the water purifier and providing rotation and angle adjustment functions, the user can clearly view the display screen from any direction, such as the front, side, or non-front position of the water purifier, thereby ensuring visibility of water quality data and control screens even in confined spaces of laboratories and various installation environments.

[0024] In addition, the present invention adopts a three-stage rotation structure composed of a base module, a rotating module, and a pair of tilting modules, thereby enabling free angle adjustment in multiple axes by combining the circumferential rotation (left-right rotation) of the rotating module and the circumferential rotation (up-down tilting) of the tilting module, and accordingly, the display can be positioned at an optimal angle to match the user's position and eye level.

[0025] In addition, the present invention can ensure stable rotational operation by preventing flow or shaking that may occur during rotational movement of the rotating module and improving the precision of the rotational trajectory by implementing a double support structure that simultaneously supports the outer surface and inner surface of the rotating module by forming a rotating guide groove and a rotating guide projection on the base module.

[0026] In addition, the present invention forms a pair of tilting guide sleeves and tilting guide protrusions on a rotating module to implement a double support structure that simultaneously supports the outer and inner surfaces of a pair of tilting modules, thereby minimizing eccentricity or instability that may occur during rotational movement of the tilting module and providing a balanced tilting operation that is symmetrical to the left and right.

[0027] In addition, the present invention securely connects the display and the rotating module through a structure comprising a fixed tab, a tilting body, and a tilting sleeve to which a pair of tilting modules are each coupled to the rear of the display, thereby enabling stable angle adjustment without the display separating or detaching from the tilting module even during tilting rotation.

[0028] In addition, the present invention provides a retractable arm structure composed of a first arm member and a second arm member in a rotating sleeve, fixes the extension length of the arm through a length-adjustable locking unit, and forms a hinge joint in the arm member so that the distance between the display and the water purifier body can be variably adjusted to the user's working position, and resolves the problem of mismatch between the water collection position and the control position by adjusting the bending angle of the display in multiple stages through the hinge joint, and enables the user to perform real-time monitoring and control through the display even from a distance from the main body.

[0029] In addition, the present invention forms a guide rail on the outer surface of the second arm member and a guide rib on the inner surface of the first arm member to restrict circumferential rotation during arm withdrawal and guide only longitudinal movement, thereby ensuring that the arm slides accurately only in a straight direction without twisting or rotating, so that the movement path of the arm is maintained consistently, and by forming a friction coating layer on the surface of the guide rail to increase frictional force, it is possible to prevent the arm from arbitrarily contracting due to its own weight or external vibration at a set position and to improve the stability of the display position.

[0030] In addition, the present invention improves user convenience by placing a torsion spring between the tilting sleeve and the tilting guide projection so that when the user removes the external force after tilting the display, the tilting sleeve automatically returns to its original angle position by the elastic restoring force of the torsion spring, thereby automatically restoring the display angle to its default position without the need to manually readjust it every time.

[0031] In addition, the present invention adopts a structure comprising a base plate, a support plate, and an elastic cushioning member in a fixed tab, so that the elastic cushioning member absorbs impacts applied from the front and side directions of the display through elastic deformation, thereby reducing the impact force transmitted to the display, preventing damage to the display, and improving the durability of the entire mounting device.

[0032] In addition, the present invention provides a locking mechanism comprising a fastening slot, a locking lever, and a locking block in the base body, so that after slidingly coupling the base module to the mounting bracket of the water purifier body, the locking lever is rotated to cause the locking block to press against the mounting bracket, thereby preventing the base module from being arbitrarily separated from or shaking the water purifier body and ensuring the structural stability of the entire mounting device.

[0033] In addition, the present invention provides a tapered support block, an elastic member, a locking member, and a detachable magnet on a base plate, so that when a display is mounted on a mounting device, a tapered mechanical coupling and a magnetic coupling are simultaneously formed, thereby stably supporting the display, and when detached, the locking member is released and the magnetic force of the magnet is overcome to easily separate it, so that tasks such as replacement, cleaning, and maintenance of the display can be easily performed.

[0038] In addition, when describing with reference to the attached drawings, identical components are assigned the same reference numeral regardless of drawing symbols, and redundant descriptions thereof are omitted. When describing embodiments, if it is determined that a detailed description of related prior art could unnecessarily obscure the essence of the embodiment, such detailed description is omitted.

[0039] FIG. 1 is a drawing showing the state in which a display mounting device according to an embodiment of the present invention is installed in a water purifier.

[0040] Referring to FIG. 1, a display mounting device (100) for a water purifier according to an embodiment of the present invention (hereinafter referred to as 'display mounting device (100)') is positioned between a water purifier body (P) equipped with a dispenser (P1) and a display (D) separated from the water purifier body (P) and controlling the operation of the water purifier body (P).

[0041] The display mounting device (100) supports the display (D) and is configured to selectively vary the position of the front direction of the display (D) through rotation and angle adjustment.

[0042] Here, the water purifier body (P) is an experimental pure and ultrapure water production device, and may be equipment that produces ultrapure water through a reverse osmosis (RO) filter and can supply purified water through a dispenser (P1).

[0043] The display (D) can display information such as the operating status of the water purifier body (P), water quality data (resistivity value, TOC, etc.), and filter replacement notifications, and can serve as an interface to control the amount of water collected, the speed of water collection, etc. through the user's touch input.

[0044] Conventionally, displays were embedded in the front of the water purifier body or attached at a fixed angle, which caused a problem where it was difficult to view the screen unless the user was positioned in front of the water purifier.

[0045] However, according to the present invention, the display (D) is separated from the water purifier body (P) and supported by a mounting device (100), and since it can rotate and adjust the angle, the user can clearly see the display screen from any direction, such as the side or non-front position, as well as the front of the water purifier, thereby ensuring visibility of water quality data and control screens even in the confined space of a laboratory and various installation environments.

[0046] FIG. 2 is a perspective view showing a display mounting device according to an embodiment of the present invention, and FIG. 3 is an exploded perspective view showing a display mounting device according to an embodiment of the present invention.

[0047] Referring to FIGS. 2 and FIGS. 3, the display mounting device (100) may include a base module (1), a rotating module (2), and a pair of tilting modules (3).

[0048] The base module (1) can be attached to and fixed to the front of the water purifier body (P).

[0049] The base module (1) is a foundation structure that supports the entire mounting device (100) on the water purifier body (P), and can perform the role of connecting the water purifier body (P) and the rotating module (2).

[0050] The base module (1) is firmly fixed to the water purifier body (P) so as to stably support the weight of the display (D) and the mounting device (100), and can transmit the load and moment generated when the user operates or moves the display (D) to the water purifier body (P).

[0051] The rotating module (2) is coupled to the base module (1) and can be rotatably positioned along the circumferential direction on the front surface of the base module (1).

[0052] The rotating module (2) can be rotated in the left and right directions (circumferential direction) relative to the base module (1), thereby adjusting the direction in which the front of the display (D) faces to the left or right.

[0053] This left and right rotation function allows the screen of the display (D) to always face the user when the user is positioned on the side of the water purifier or working while moving around in the laboratory.

[0054] For example, when a water purifier is placed in the corner of an experiment table, if a user approaches from the left, the rotating module (2) can be rotated to the left so that the display (D) faces the user.

[0055] A pair of tilting modules (3) may have a portion attached to the rear of the display (D) and the other portion attached to both sides of the rotating module (2).

[0056] A pair of tilting modules (3) can be rotatably positioned along the circumferential direction on the side of the rotating module (2).

[0057] The tilting module (3) can adjust the angle of the display (D) upward or downward by rotating it in the up-and-down direction (circumferential direction) relative to the rotating module (2).

[0058] This vertical tilting function allows for optimal visibility by adjusting the angle of the screen when the user's eye level is higher or lower than the display (D).

[0059] For example, when the water purifier is placed in the lower space and the position of the display (D) is low, the tilting module (3) can be rotated upward to adjust the screen of the display (D) so that it faces upward.

[0060] A pair of tilting modules (3) are symmetrically positioned on both sides of the rotating module (2) so that the weight of the display (D) is evenly supported and the moment generated during tilting rotation can be evenly distributed to the left and right.

[0061] That is, the present invention adopts a three-stage rotation structure composed of a base module (1), a rotating module (2), and a pair of tilting modules (3), thereby enabling free angle adjustment in multiple axes by combining the circumferential rotation (left and right rotation) of the rotating module (2) and the circumferential rotation (up and down tilting) of the tilting module (3), and accordingly, the display (D) can be positioned at an optimal angle to match the user's position and eye level.

[0062] In particular, since users use the water purifier in various locations in a laboratory environment, the screen orientation of the display (D) can be freely adjusted within a 360-degree range by combining left-right rotation and up-down tilting, thereby ensuring optimal visibility from any position.

[0063] The base module (1) may include a base body (11), a rotating guide groove (12), and a rotating guide projection (13).

[0064] The base body (11) is attached to the front of the water purifier body (P), and the center may protrude forward.

[0065] The base body (11) is a flat-shaped base member fixed to the water purifier body (P), and may have a structure in which the rear side is in close contact with the front side of the water purifier body (P) and the front side supports the rotating module (2).

[0066] By protruding the center of the base body (11) forward, a space is secured for the rotating module (2) to rotate, and a three-dimensional structure is provided that can form a rotating guide groove (12) and a rotating guide projection (13).

[0067] The base body (11) may be made of a metal material (e.g., aluminum alloy, stainless steel) or a high-strength plastic material (e.g., ABS, PC / ABS alloy) and must have sufficient rigidity and durability to withstand the weight of the entire mounting device (100) and external forces.

[0068] The rotating guide groove (12) is recessed in the center of the base body (11) and supports the outer surface of the rotating module (2) inserted inside to guide the rotation of the rotating module (2).

[0069] The rotating guide groove (12) is a groove structure formed by being recessed in a circular or ring shape at the front center of the base body (11), and can provide a space into which the rotating sleeve (22) of the rotating module (2) can be inserted.

[0070] The inner surface of the rotating guide groove (12) contacts the outer surface of the rotating sleeve (22), thereby guiding the rotational trajectory when the rotating sleeve (22) rotates in the circumferential direction and preventing deviation in the radial direction.

[0071] The depth of the rotating guide groove (12) can be set so that the rotating sleeve (22) can be sufficiently inserted and stably supported, and can generally be formed to be at least 50%, preferably at least 70%, of the height of the rotating sleeve (22).

[0072] A bearing member or a low-friction coating layer (e.g., Teflon coating, lubricant coating) may be applied to the inner surface of the rotating guide groove (12), thereby reducing the rotational resistance of the rotating module (2) and enabling smooth rotational movement.

[0073] The rotating guide projection (13) protrudes from the center of the rotating guide groove (12) and is inserted into the interior of the rotating module (2) inserted into the rotating guide groove (12) to support the inner surface of the rotating module (2).

[0074] The rotating guide projection (13) is a cylindrical or truncated cone-shaped projection structure protruding forward from the center of the bottom surface of the rotating guide groove (12), and can be inserted into the internal space of the rotating sleeve (22).

[0075] The outer surface of the rotating guide projection (13) contacts the inner surface of the rotating sleeve (22), and guides the rotational trajectory from the inside when the rotating sleeve (22) rotates in the circumferential direction, and can prevent the rotating sleeve (22) from becoming eccentric or shaking from the central axis.

[0076] The height of the rotating guide projection (13) can be set so that the rotating sleeve (22) is sufficiently supported, and can generally be formed to be at least 30%, preferably at least 50%, of the height of the rotating sleeve (22).

[0077] A bearing member or a low-friction coating layer may also be applied to the outer surface of the rotating guide projection (13), thereby further reducing the rotational resistance of the rotating module (2).

[0078] That is, the present invention forms a rotating guide groove (12) and a rotating guide projection (13) on the base module (1) to implement a double support structure that simultaneously supports the outer surface and the inner surface of the rotating module (2), thereby preventing flow or shaking that may occur during the rotational movement of the rotating module (2) and improving the precision of the rotational trajectory, thereby ensuring stable rotational operation.

[0079] In particular, when the weight of the display (D) acts as an eccentric load on the rotating module (2), the rotating guide groove (12) and the rotating guide projection (13) support it simultaneously from the outside and the inside, thereby preventing the rotating module (2) from tilting or the rotation axis from shaking, and maintaining smooth and precise rotational movement.

[0080] In addition, the double support structure can increase the contact area between the rotating module (2) and the base module (1), thereby providing a load distribution effect and preventing stress from concentrating in specific areas, which can improve structural durability.

[0081] The rotating module (2) may include a rotating body (21), a rotating sleeve (22), a pair of tilting guide sleeves (23), and a pair of tilting guide projections (24).

[0082] The rotating body (21) can be formed in a flat plate shape.

[0083] The rotating body (21) is the main structure of the rotating module (2), and a rotating sleeve (22) is connected to the rear side, and a pair of tilting guide sleeves (23) and a pair of tilting guide protrusions (24) may be formed on both sides.

[0084] The rotating body (21) can be formed in a circular, elliptical, or polygonal flat shape and can have a left-right symmetrical structure centered on the rotating sleeve (22).

[0085] The thickness of the rotating body (21) must have sufficient rigidity to withstand the moment generated when the tilting module (3) rotates, and can generally be formed to be 5 mm or more, preferably 10 mm or more.

[0086] The rotating body (21) can be made of a metal material (e.g., aluminum alloy, stainless steel) or a high-strength plastic material (e.g., ABS, PC / ABS alloy).

[0087] The rotating sleeve (22) can be inserted into the rotating guide groove (12) by protruding from the rear of the rotating body (21).

[0088] The outer surface of the rotating sleeve (22) is supported by the rotating guide groove (12), and the inner surface is supported by the rotating guide projection (13), so that it can be rotatably positioned along the circumferential direction.

[0089] The rotating sleeve (22) is an annular sleeve structure protruding backward from the rear center of the rotating body (21), and its outer surface contacts the inner surface of the rotating guide groove (12), and its inner surface contacts the outer surface of the rotating guide projection (13).

[0090] The rotating sleeve (22) can rotate circumferentially relative to the base module (1), and the rotation angle can generally be ±180 degrees, i.e., freely rotated over a full 360-degree range.

[0091] However, if necessary, a stopper that limits the rotation angle of the rotating sleeve (22) may be provided, and, for example, the rotation may be limited to a range of ±90 degrees or ±120 degrees.

[0092] The rotational resistance of the rotating sleeve (22) can be adjusted so that the user can rotate it with appropriate force, and it can be set so that it is not too light so that it does not rotate arbitrarily due to its own weight, but not too heavy so that the user can rotate it easily.

[0093] To this end, a friction member (e.g., O-ring, friction pad) or a damping member (e.g., viscous fluid, magnetic damper) that generates appropriate frictional force between the rotating sleeve (22) and the rotating guide groove (12) and between the rotating sleeve (22) and the rotating guide projection (13) may be provided.

[0094] A pair of tilting guide sleeves (23) are positioned at both ends of the rotating body (21) and can guide the rotation of a pair of tilting modules (3) by supporting the outer surface of a pair of tilting modules (3) inserted into it.

[0095] A pair of tilting guide sleeves (23) are annular sleeve structures formed on the left and right sides of the rotating body (21), respectively, and can provide a space into which the tilting sleeve (33) of the tilting module (3) can be inserted.

[0096] A pair of tilting guide sleeves (23) are symmetrically arranged on the same axis so that a pair of tilting modules (3) can rotate around the same axis of rotation.

[0097] The inner surface of the tilting guide sleeve (23) contacts the outer surface of the tilting sleeve (33), thereby guiding the rotational trajectory when the tilting sleeve (33) rotates in the circumferential direction and preventing deviation in the radial direction.

[0098] The depth of the tilting guide sleeve (23) can be set so that the tilting sleeve (33) can be sufficiently inserted and stably supported, and can generally be formed to be at least 50%, preferably at least 70%, of the height of the tilting sleeve (33).

[0099] A bearing member or a low-friction coating layer (e.g., Teflon coating, lubricant coating) may be applied to the inner surface of the tilting guide sleeve (23), thereby reducing the rotational resistance of the tilting module (3) and enabling smooth rotational movement.

[0100] A pair of tilting guide protrusions (24) protrude from the center of a pair of tilting guide sleeves (23) and are inserted into the interior of a pair of tilting modules (3) inserted into the pair of tilting guide sleeves (23) to support the inner surface of the pair of tilting modules (3).

[0101] A pair of tilting guide projections (24) are cylindrical or truncated cone-shaped projection structures protruding outward from the center of a pair of tilting guide sleeves (23) and can be inserted into the internal space of the tilting sleeve (33).

[0102] A pair of tilting guide projections (24) are symmetrically arranged on the same axis so that a pair of tilting modules (3) can rotate around the same axis of rotation.

[0103] The outer surface of the tilting guide projection (24) contacts the inner surface of the tilting sleeve (33), and guides the rotational trajectory from the inside when the tilting sleeve (33) rotates in the circumferential direction, thereby preventing the tilting sleeve (33) from becoming eccentric or shaking away from the central axis.

[0104] The height of the tilting guide projection (24) can be set so that the tilting sleeve (33) is sufficiently supported, and can generally be formed to be at least 30%, preferably at least 50%, of the height of the tilting sleeve (33).

[0105] A bearing member or a low-friction coating layer may also be applied to the outer surface of the tilting guide projection (24), thereby further reducing the rotational resistance of the tilting module (3).

[0106] That is, the present invention forms a pair of tilting guide sleeves (23) and tilting guide protrusions (24) on a rotating module (2) to implement a double support structure that simultaneously supports the outer surface and inner surface of a pair of tilting modules (3), thereby minimizing eccentricity or instability that may occur during rotational movement of the tilting module (3) and providing a balanced tilting operation that is symmetrical to the left and right.

[0107] In particular, when the weight of the display (D) acts on a pair of tilting modules (3), the tilting guide sleeve (23) and the tilting guide projection (24) support it simultaneously from the outside and the inside, thereby preventing the tilting module (3) from tilting or the rotation axis from shaking, and maintaining smooth and precise rotational movement.

[0108] In addition, a pair of tilting modules (3) are symmetrically arranged on the same axis and each is supported by a double support structure, so that the weight of the display (D) is evenly distributed to the left and right, preventing excessive load from being concentrated on one of the tilting modules (3) and improving structural stability and durability.

[0109] A pair of tilting modules (3) may each include a fixed tab (31), a tilting body (32), and a tilting sleeve (33).

[0110] The fixing tab (31) can be attached to the back of the display (D) and fixed to the display (D).

[0111] The fixing tab (31) can be formed in a flat shape and can be firmly fixed to the back of the display (D) by means such as screw fastening, adhesive, or magnetic coupling.

[0112] The fixed tab (31) serves as an interface connecting the display (D) and the tilting module (3), transmits the weight of the display (D) to the tilting body (32), and can support the moment generated during tilting rotation.

[0113] The fixing tabs (31) of a pair of tilting modules (3) can be symmetrically positioned on the rear left and right sides of the display (D), thereby evenly supporting the weight of the display (D).

[0114] The tilting body (32) can be extended from the fixed tab (31) and positioned coaxially in the tilting guide sleeve (23).

[0115] The tilting body (32) is an intermediate structure connecting the fixed tab (31) and the tilting sleeve (33), and can be positioned on the side of the rotating module (2) by extending laterally from the fixed tab (31).

[0116] The tilting body (32) can be formed in a cylindrical shape, a truncated cone shape, or a prismatic shape, and can be arranged to be coaxial with the tilting guide sleeve (23) and the tilting guide projection (24).

[0117] The tilting body (32) must have sufficient rigidity to withstand the moment generated during tilting rotation and can be made of a metal material (e.g., aluminum alloy, stainless steel) or a high-strength plastic material (e.g., ABS, PC / ABS alloy).

[0118] The tilting sleeve (33) can be inserted into the tilting guide sleeve (23) by protruding from the inner surface of the tilting body (32).

[0119] The outer surface of the tilting sleeve (33) is supported by the tilting guide sleeve (23), and the inner surface is supported by the tilting guide projection (24), so that it can be rotatably positioned along the circumferential direction.

[0120] The tilting sleeve (33) is an annular sleeve structure protruding inward from the inner surface of the tilting body (32), and its outer surface contacts the inner surface of the tilting guide sleeve (23), and its inner surface contacts the outer surface of the tilting guide projection (24).

[0121] The tilting sleeve (33) can rotate circumferentially relative to the rotating module (2), and the rotation angle can generally be ±45 degrees, i.e., rotated over a full 90-degree range.

[0122] However, if necessary, a stopper that limits the rotation angle of the tilting sleeve (33) may be provided, and the rotation may be limited to, for example, ±30 degrees or ±60 degrees.

[0123] The rotational resistance of the tilting sleeve (33) can be adjusted so that the user can rotate it with appropriate force, and it can be set so that it is not too light so that it does not rotate arbitrarily due to its own weight, but not too heavy so that the user can rotate it easily.

[0124] To this end, a friction member (e.g., O-ring, friction pad) or a damping member (e.g., viscous fluid, magnetic damper) that generates appropriate frictional force between the tilting sleeve (33) and the tilting guide sleeve (23), and between the tilting sleeve (33) and the tilting guide projection (24) may be provided.

[0125] That is, the present invention securely connects the display (D) and the rotating module (2) through a structure comprising a fixed tab (31) to which a pair of tilting modules (3) are each coupled to the rear of the display (D), a tilting body (32), and a tilting sleeve (33), thereby allowing the display (D) to be stably adjusted in angle without being separated or detached from the tilting module (3) even during tilting rotation.

[0126] In particular, through a structure in which a fixed tab (31) is attached to the rear of the display (D) over a large area and a tilting sleeve (33) is double-supported by a tilting guide sleeve (23) and a tilting guide projection (24), the weight of the display (D) and the moment generated during tilting rotation are distributed throughout the structure, thereby preventing stress from concentrating in specific areas and maintaining structural stability and durability even during long-term use.

[0127] FIG. 4 is a drawing showing a rotating sleeve according to an embodiment of the present invention, and FIG. 5 is a drawing showing a combined structure of a first arm member and a second arm member according to an embodiment of the present invention.

[0128] Referring to FIG. 4, the rotating sleeve (22) may include a first arm member (221), a second arm member (222), and a length adjustment locking unit (223).

[0129] The first arm member (221) extends from the rotating body (21) and may have a receiving space inside.

[0130] The first arm member (221) is a hollow member that is connected to the front part of the rotating sleeve (22) and extends forward, and may have a receiving space inside into which the second arm member (222) can be inserted.

[0131] The first arm member (221) may have a cross-sectional shape such as a circle, ellipse, square, or hexagon, and preferably has a circular cross-section to facilitate the sliding movement of the second arm member (222).

[0132] The length of the first arm member (221) can be set differently depending on the usage environment.

[0133] The wall thickness of the first arm member (221) can have sufficient rigidity to support the second arm member (222) and withstand the weight of the arm itself and the weight of the display (D).

[0134] The first arm member (221) can be made of a metal material (e.g., aluminum alloy, stainless steel) or a high-strength plastic material (e.g., ABS, PC / ABS alloy).

[0135] The second arm member (222) can be inserted into the interior of the first arm member (221) and coupled so as to be slidably moved in the longitudinal direction.

[0136] The second arm member (222) is a solid or hollow member inserted into the receiving space of the first arm member (221) and can slide forward and backward relative to the first arm member (221).

[0137] The cross-sectional shape of the second arm member (222) can be formed to correspond to the internal cross-sectional shape of the first arm member (221), and can have an appropriate clearance so as to allow smooth sliding movement inside the first arm member (221).

[0138] The length of the second arm member (222) may be formed to be similar to or slightly longer than the length of the first arm member (221).

[0139] When the second arm member (222) is completely withdrawn from the first arm member (221), the total length of the arm may be the sum of the lengths of the first arm member (221) and the second arm member (222), excluding the overlapping portion.

[0140] The second arm member (222) can be made of a metal material (e.g., aluminum alloy, stainless steel) or a high-strength plastic material (e.g., ABS, PC / ABS alloy).

[0141] The length adjustment locking unit (223) is provided between the first arm member (221) and the second arm member (222) to fix the extension length of the second arm member (222).

[0142] The length adjustment locking unit (223) may be a device that fixes the second arm member (222) so that it does not move further at that position after the user has withdrawn the second arm member (222) to a desired length.

[0143] The length adjustment locking unit (223) can be implemented in various forms.

[0144] For example, the length adjustment locking unit (223) may place a friction member (e.g., rubber pad, silicone pad) on the inner surface of the first arm member (221) and operate a lever or screw so that the friction member presses against the outer surface of the second arm member (222), thereby restricting the movement of the second arm member (222) by frictional force.

[0145] As another example, the length adjustment locking unit (223) may form a plurality of holes along the length direction on the outer surface of the second arm member (222) and provide a pin on the first arm member (221) so that the movement of the second arm member (222) may be restricted by inserting the pin into the hole.

[0146] As another example, the length adjustment locking unit (223) forms a clamp structure at the end of the first arm member (221), and by operating a lever, the clamp can tighten the second arm member (222), thereby restricting the movement of the second arm member (222).

[0147] Additionally, the length adjustment locking unit (223) is not necessarily limited to this and may have an operating member in the form of a lever, button, or dial so that the user can easily operate it, and may provide visual or tactile feedback that can clearly distinguish between the locked and unlocked states.

[0148] Meanwhile, at least one of the first arm member (221) and the second arm member (222) may be configured to have a hinge joint (H) formed at an intermediate point in the longitudinal direction to adjust the separation distance and bending angle of the display (D) in multiple stages.

[0149] The hinge joint (H) may be a joint structure that divides the arm member into two segments and rotatably connects the two segments.

[0150] The arm member having a hinge joint (H) can be bent around the hinge joint (H), for example, from a straight state (180 degrees) to an angle such as 90 degrees, 120 degrees, or 150 degrees, thereby allowing the position and direction of the display (D) to be adjusted in various ways.

[0151] The hinge joint (H) may be formed at the midpoint of the first arm member (221), the midpoint of the second arm member (222), or the midpoint of both arm members.

[0152] Through this, the position of the display (D) can be adjusted more precisely.

[0153] That is, the present invention provides a retractable arm structure composed of a first arm member (221) and a second arm member (222) in a rotating sleeve (22), fixes the extension length of the arm through a length adjustment locking unit (223), and forms a hinge joint (H) in the arm member so that the distance between the display (D) and the water purifier body (P) can be variably adjusted to the user's working position, and resolves the problem of mismatch between the water collection position and the control position by adjusting the bending angle of the display (D) in multiple stages through the hinge joint (H), and allows the user to perform real-time monitoring and control through the display (D) even from a distance from the main body.

[0154] In particular, laboratory water purifiers are often used by moving the water collection gun to a location away from the main body to collect water in beakers or large-capacity carboys. Since the display (D) can be moved to the water collection location through the telescopic arm structure, the user can check and control the water quality status and water collection amount in real time without repeatedly moving between the main body and the water collection location, thereby greatly improving work efficiency.

[0155] In addition, since the arm can be bent through the hinge joint (H), the display (D) can be moved not only in a straight direction but also upward, downward, or sideways, allowing the optimal position to be set according to the user's eye level and work environment.

[0156] Referring to FIG. 5, a guide rail (222A) may be formed indented along the longitudinal direction on the outer surface of the second arm member (222), and a guide rib (221A) corresponding to the guide rail (222A) may be formed on the inner surface of the first arm member (221).

[0157] The guide rail (222A) may be a groove structure formed by being recessed along the longitudinal direction on the outer surface of the second arm member (222).

[0158] The guide rib (221A) is a projection structure formed along the longitudinal direction on the inner circumference of the first arm member (221) and can be inserted into the guide rail (222A).

[0159] When the second arm member (222) is withdrawn, circumferential rotation is constrained by the combination of the guide rail (222A) and the guide rib (221A), but only longitudinal movement can be guided.

[0160] The guide rail (222A) and guide rib (221A) can serve to restrain the second arm member (222) so that it moves only in a straight direction without rotating when the second arm member (222) slides relative to the first arm member (221).

[0161] One or more guide rails (222A) may be formed on the outer surface of the second arm member (222), and when multiple guide rails (222A) are formed, they may be evenly distributed in the circumferential direction to improve the rotational restraint effect of the second arm member (222).

[0162] For example, when two guide rails (222A) are formed, they can be arranged at 180-degree intervals; when three guide rails (222A) are formed, they can be arranged at 120-degree intervals; and when four guide rails (222A) are formed, they can be arranged at 90-degree intervals.

[0163] A suitable clearance is maintained between the guide rail (222A) and the guide rib (221A) so that the second arm member (222) can slide smoothly relative to the first arm member (221).

[0164] A friction coating layer (222B) can be formed on the surface of the guide rail (222A).

[0165] The friction coating layer (222B) is a coating layer that increases the frictional force between the guide rail (222A) and the guide rib (221A), and provides appropriate resistance when the second arm member (222) moves, and can prevent the second arm member (222) from moving arbitrarily at a set position.

[0166] The friction coating layer (222B) can be formed from a high-friction material, for example, rubber, silicone, urethane, or a high-friction coating agent (e.g., sandblasting treatment, grip coating).

[0167] The thickness of the friction coating layer (222B) can be formed to be 10% to 50%, preferably 20% to 40%, of the depth of the guide rail (222A), and can generate frictional force by contacting the guide rib (221A) with appropriate pressure.

[0168] The friction coating layer (222B) may be formed on the entire surface of the guide rail (222A), or may be selectively formed only on some sections.

[0169] For example, a friction coating layer (222B) can be formed thinly in the initial withdrawal section of the second arm member (222) to facilitate movement, and a friction coating layer (222B) can be formed thickly in the final withdrawal section to increase friction.

[0170] Additionally, a friction coating layer may be formed on the surface of the guide rib (221A), in which case the friction coating layer is formed on both the guide rail (222A) and the guide rib (221A) to further increase the frictional force.

[0171] That is, the present invention forms a guide rail (222A) on the outer surface of the second arm member (222) and a guide rib (221A) on the inner surface of the first arm member (221) to restrict circumferential rotation when the arm is withdrawn and to guide only longitudinal movement, thereby ensuring that the arm slides accurately only in a straight direction without twisting or rotating, so that the movement path of the arm is maintained consistently, and by forming a friction coating layer (222B) on the surface of the guide rail (222A) to increase frictional force, the arm is prevented from arbitrarily contracting due to its own weight or external vibration at a set position and the stability of the display (D) position can be improved.

[0172] In particular, when the weight of the display (D) acts on the tip of the arm and a moment is generated in which the arm tends to sag downward, the combination of the guide rail (222A) and the guide rib (221A) restrains the rotation of the arm, and the friction coating layer (222B) provides frictional force to prevent the arm from contracting, thereby allowing the display (D) to be stably maintained in a set position.

[0173] Additionally, the guide rail (222A) and the guide rib (221A) perform an alignment function during the sliding movement of the second arm member (222), guiding the second arm member (222) to move accurately along the central axis of the first arm member (221), and preventing the second arm member (222) from coming into uneven contact with the inner wall of the first arm member (221) and becoming worn or damaged.

[0174] FIG. 6 is a diagram showing the combined structure of a tilting sleeve and a tilting guide projection according to an embodiment of the present invention.

[0175] Referring to FIG. 6, the display mounting device (100) may further include a torsion spring (4) positioned between the tilting sleeve (33) and the tilting guide projection (24).

[0176] The torsion spring (4) is positioned between the tilting sleeve (33) and the tilting guide projection (24), so that one end is fixed to the side of the tilting sleeve (33) and the other end is fixed to the side of the tilting guide projection (24).

[0177] The torsion spring (4) is a type of coil spring and may have a structure in which a coil is wound along a central axis and both ends extend radially from the central axis.

[0178] The central axis of the torsion spring (4) can be positioned to coincide with the rotation axis of the tilting sleeve (33) and the tilting guide projection (24), and one end of the torsion spring (4) can be coupled to a fixing groove or fixing pin formed on the inner circumference of the tilting sleeve (33), and the other end can be coupled to a fixing groove or fixing pin formed on the outer circumference of the tilting guide projection (24).

[0179] The spring constant of the torsion spring (4) can be appropriately set according to the weight and tilting angle of the display (D), and generally, it can be set so that the display (D) is stably maintained in a horizontal position (0 degrees) and the user can tilt it with appropriate force.

[0180] The torsion spring (4) can be made of a metal material such as stainless steel, carbon steel, or titanium alloy, and must have durability against repeated torsional deformation.

[0181] Therefore, when the tilting sleeve (33) is rotated, the torsion spring (4) is elastically deformed, and when the external force applied to the tilting sleeve (33) is removed, it is restored to its original state by the elastic force, thereby returning the tilting sleeve (33) to its original angle position.

[0182] That is, the present invention improves user convenience by placing a torsion spring (4) between the tilting sleeve (33) and the tilting guide projection (24), so that when the user removes the external force after tilting the display (D), the tilting sleeve (33) automatically returns to its original angle position by the elastic restoring force of the torsion spring (4), thereby automatically restoring the display (D) to its basic position without the need to manually readjust the angle every time.

[0183] In particular, in a laboratory environment, users often use the water purifier repeatedly while conducting multiple experiments. Since the display (D) always returns to its default position (e.g., horizontal position) through the automatic restoration function of the torsion spring (4), the user can check and control the display (D) immediately without any separate operation during the next use.

[0184] Additionally, the torsion spring (4) provides appropriate resistance when the tilting sleeve (33) rotates, preventing the display (D) from suddenly falling downward due to its own weight and allowing the user to adjust the tilting angle in a smooth and controllable manner.

[0185] FIG. 7 is a drawing showing the internal structure of a fixing tab according to an embodiment of the present invention.

[0186] Referring to FIG. 7, the fixed tab (31) may include a base plate (311), a support plate (312), and an elastic cushioning member (313).

[0187] The base plate (311) can be attached to the rear of the display (D).

[0188] The base plate (311) can be formed in a flat shape and can be firmly fixed to the back of the display (D) by means such as screw fastening, adhesive, or magnetic coupling.

[0189] The base plate (311) can be formed to a size sufficient to support the weight of the display (D).

[0190] The base plate (311) can be made of a metal material (e.g., aluminum alloy, stainless steel) or a high-strength plastic material (e.g., ABS, PC / ABS alloy).

[0191] The support plate (312) can be positioned at the end of the tilting body (32) and positioned opposite the base plate (311).

[0192] The support plate (312) can be formed in a flat shape and can be fixed to the end of the tilting body (32) and positioned to face the base plate (311).

[0193] The area of ​​the support plate (312) may be formed to be similar to or slightly smaller than the area of ​​the base plate (311), and may be formed to a size capable of supporting the elastic cushioning member (313).

[0194] The support plate (312) can be made of a metal material (e.g., aluminum alloy, stainless steel) or a high-strength plastic material (e.g., ABS, PC / ABS alloy).

[0195] The elastic cushioning member (313) is positioned between the base plate (311) and the support plate (312) and can absorb impact by causing elastic deformation in response to impact applied from the front and side directions of the base plate (311).

[0196] The elastic cushioning member (313) can be made of an elastic material, for example, rubber, silicone, urethane, or a spring.

[0197] A plurality of elastic cushioning members (313) may be placed between the base plate (311) and the support plate (312), and when a plurality of elastic cushioning members (313) are placed, they may be evenly distributed at the corners or center of the base plate (311) to improve the shock absorption effect.

[0198] The elastic cushioning member (313) can absorb shocks applied from the front direction (a direction perpendicular to the screen of the display (D)) as well as from the side direction (a direction parallel to the screen of the display (D)).

[0199] For example, when a user touches the screen of the display (D) to operate it, the elastic cushioning member (313) can absorb the pressure applied in the front direction, and when the display (D) is moved left and right or up and down, the elastic cushioning member (313) can absorb the inertial force applied in the side direction.

[0200] That is, the present invention adopts a structure including a base plate (311), a support plate (312), and an elastic cushioning member (313) in a fixed tab (31), so that the elastic cushioning member (313) absorbs impacts applied from the front and side directions of the display (D) through elastic deformation, thereby reducing the impact force transmitted to the display (D), preventing damage to the display (D), and improving the overall durability of the mounting device (100).

[0201] In particular, in a laboratory environment, users often work quickly and repeatedly touch or move the display (D). By absorbing such shocks, the elastic cushioning member (313) prevents damage to the liquid crystal panel, touch sensor, or internal circuit of the display (D) and maintains stable performance even during long-term use.

[0202] Additionally, the elastic cushioning member (313) can also perform the role of blocking vibration transmission between the display (D) and the tilting body (32), and prevents vibrations generated from the pump, valve, or motor of the water purifier body (P) from being transmitted to the display (D) through the mounting device (100), thereby allowing the screen display of the display (D) to remain clear without shaking.

[0203] FIG. 8 is a drawing showing the combined structure of a base body and a water purifier body according to an embodiment of the present invention.

[0204] Referring to FIG. 8, the base body (11) may include a fastening slot (111), a locking lever (113), and a locking block (114).

[0205] The connection slot (111) is formed on the rear side of the base body (11) and can be slidably connected from top to bottom to a hook-shaped mounting bracket (P2) formed on the front side of the water purifier body (P).

[0206] The fastening slot (111) is a groove structure extending in the vertical direction on the rear of the base body (11), and can provide a space into which a mounting bracket (P2) can be inserted.

[0207] The mounting bracket (P2) is a hook-shaped member fixed to the front of the water purifier body (P), and may have a shape in which the tip is bent forward and downward.

[0208] When installing the base body (11) on the water purifier body (P), the user can position the fastening slot (111) of the base body (11) above the mounting bracket (P2) and slide the base body (11) downward so that the fastening slot (111) is coupled to the mounting bracket (P2).

[0209] The width of the fastening slot (111) is formed to be slightly larger than the thickness of the mounting bracket (P2), so that the mounting bracket (P2) can be smoothly inserted into and slid into the fastening slot (111).

[0210] The length of the fastening slot (111) can be formed to be 30% to 70%, preferably 40% to 60%, of the height of the base body (11), so that the mounting bracket (P2) can be sufficiently inserted and stably supported.

[0211] A part of the locking lever (113) is rotatably coupled to the base body (11), and another part can be received in a storage groove (112) formed inside the base body (11) and communicating with the fastening slot (111).

[0212] The locking lever (113) is a lever member hinged to the base body (11) and may have a handle portion that can be rotated by a user and a cam portion that can press the locking block (114).

[0213] The hinge axis of the locking lever (113) can be positioned on the side of the base body (11), and the locking lever (113) can rotate in the forward and backward directions around the hinge axis.

[0214] The storage groove (112) is a space formed inside the base body (11) and is connected to the fastening slot (111) to provide a space in which the locking block (114) can be received and moved.

[0215] The size of the storage groove (112) can provide sufficient space for the locking block (114) to move in the forward and backward directions.

[0216] The locking block (114) is received in the storage groove (112), and when the locking lever (113) is rotated, it is pressed against the locking lever (113) and protrudes toward the fastening slot (111), thereby pressing and fixing the mounting bracket (P2) coupled to the fastening slot (111).

[0217] The locking block (114) is a block-shaped member received in the storage groove (112) and may have a rear surface that contacts the cam portion of the locking lever (113) and a front surface that presses the mounting bracket (P2).

[0218] When the locking lever (113) is in the unlocked position, the cam portion of the locking lever (113) is separated from the rear of the locking block (114), so that the locking block (114) is positioned at the rear of the storage groove (112) and does not press the mounting bracket (P2).

[0219] In this state, the base body (11) can freely slide up and down relative to the mounting bracket (P2).

[0220] When the user rotates the locking lever (113) to the lock position, the cam portion of the locking lever (113) presses against the rear of the locking block (114), causing the locking block (114) to move forward toward the storage groove (112) and protrude toward the fastening slot (111), and the front of the locking block (114) presses against the rear of the mounting bracket (P2).

[0221] At this time, the mounting bracket (P2) is strongly fixed between the front wall of the fastening slot (111) and the locking block (114), so that the base body (11) is prevented from moving up and down or shaking in the front and back directions relative to the mounting bracket (P2).

[0222] The front surface of the locking block (114) can be formed to correspond to the rear surface shape of the mounting bracket (P2), for example, by being formed as a flat, curved, or protruding shape to increase the contact area with the mounting bracket (P2) and improve the fixing force.

[0223] A high-friction material (e.g., rubber, silicone) or a sawtooth grip pattern may be formed on the front surface of the locking block (114), thereby increasing the frictional force with the mounting bracket (P2) and further improving the fixing force.

[0224] That is, the present invention provides a locking mechanism comprising a fastening slot (111), a locking lever (113), and a locking block (114) in the base body (11), so that after slidingly coupling the base module (1) to the mounting bracket (P2) of the water purifier body (P), the locking lever (113) is rotated to cause the locking block (114) to press against the mounting bracket (P2), thereby preventing the base module (1) from being arbitrarily separated from or shaken by the water purifier body (P) and ensuring the structural stability of the entire mounting device (100).

[0225] In particular, in a laboratory environment, external forces of various directions may be applied to the mounting device (100) while the user repeatedly manipulates or moves the display (D). However, by firmly fixing the base module (1) to the water purifier body (P) through the locking mechanism, it is possible to prevent the mounting device (100) from detaching from or shaking the water purifier body (P) and thus preventing the screen display of the display (D) from becoming unstable.

[0226] In addition, the locking mechanism can be released by operating the locking lever (113), so that the base module (1) can be easily detached from the water purifier body (P) when necessary to perform maintenance, cleaning, or replacement work on the mounting device (100).

[0227] FIG. 9 is a diagram showing the combined structure of a base plate and a display according to an embodiment of the present invention.

[0228] Referring to FIG. 9, the base plate (311) may include a support block (311A), an elastic member (311B), a locking member (311C), and detachable magnets (311D).

[0229] The support block (311A) is formed in a tapered shape that protrudes from the front of the base plate (311) and becomes narrower as it goes downward, and can be coupled to a tapered coupling groove (D1) formed on the rear of the display (D) to support the display (D).

[0230] The support block (311A) is a protruding structure that protrudes forward from the front center of the base plate (311), and the lower part may be formed in a tapered shape (a trapezoidal or triangular shape with a wide upper part and a narrow lower part).

[0231] A tapered coupling groove (D1) corresponding to a support block (311A) is formed on the rear surface of the display (D), so that the support block (311A) can be inserted into the coupling groove (D1).

[0232] The tapered shape of the support block (311A) and the coupling groove (D1) facilitates coupling in the vertical direction and enables self-centering during coupling, and can perform a mechanical restraint function to prevent deviation in the front-back and left-right directions after coupling.

[0233] The elastic member (311B) can be attached to the upper part of the support block (311A).

[0234] The elastic member (311B) can be made of an elastic material such as a spring, rubber, or silicone, and is positioned between the upper part of the support block (311A) and the catch member (311C) to elastically support the catch member (311C) upward.

[0235] The catch member (311C) is coupled to the upper part of the elastic member (311B) and can be supported by being caught in the catch groove (D2) formed on the upper part of the coupling groove (D1).

[0236] The catch member (311C) is a hook-shaped, protruding, or ball-shaped member that can be caught in the catch groove (D2) while being elastically supported upward by the elastic member (311B).

[0237] That is, when mounting the display (D) on the base plate (311), the user can position the coupling groove (D1) of the display (D) above the support block (311A) and move the display (D) downward so that the coupling groove (D1) is coupled to the support block (311A).

[0238] At this time, since the locking member (311C) is pushed upward by the elastic member (311B), when the display (D) moves downward, the locking member (311C) comes into contact with the rear surface of the display (D) and can be temporarily pressed downward by the elastic force of the elastic member (311B).

[0239] When the display (D) is completely moved downward and the coupling groove (D1) is completely coupled to the support block (311A), the locking member (311C) reaches the position of the locking groove (D2), and is restored upward by the elastic force of the elastic member (311B) and gets caught in the locking groove (D2).

[0240] In this state, the display (D) is fixed in the vertical direction by the support block (311A) and the locking member (311C), so that it can be prevented from moving upward.

[0241] When separating the display (D) from the base plate (311), the user can press the locking member (311C) downward to release it from the locking groove (D2) and lift the display (D) upward so that the coupling groove (D1) is separated from the support block (311A).

[0242] The detachable magnets (311D) are installed on the front of the base plate (311) and positioned on the upper and lower parts of the support block (311A), and can be detachably coupled to fixed magnets (D3) embedded in the rear of the display (D) through magnetic force.

[0243] Detachable magnets (311D) are symmetrically distributed on the upper and lower parts of the support block (311A) to provide magnetic force coupling with the display (D).

[0244] The fixed magnets (D3) are magnets embedded in the back of the display (D) and can be placed at positions corresponding to the detachable magnets (311D).

[0245] The detachable magnets (311D) and the fixed magnets (D3) are arranged to have opposite polarities (N and S poles) so that an attractive force can be exerted by magnetic force.

[0246] When mounting the display (D) on the base plate (311), the magnetic force between the detachable magnets (311D) and the fixed magnets (D3) acts so that the display (D) can be attached to the base plate (311) and stably supported.

[0247] The magnetic force of the detachable magnets (311D) and the fixed magnets (D3) can be strong enough to support the weight of the display (D) and prevent it from moving in the forward, backward, left, and right directions.

[0248] Accordingly, when separating the display (D) from the base plate (311), the user can release the locking member (311C) and lift the display (D) upward to overcome the magnetic force between the detachable magnets (311D) and the fixed magnets (D3) and separate the display (D).

[0249] The detachable magnets (311D) and fixed magnets (D3) can be implemented with various types of permanent magnets, such as neodymium (Nd-Fe-B) magnets, ferrite magnets, or Alnico magnets, and neodymium magnets can be preferably used as they provide high magnetic force.

[0250] That is, the present invention provides a base plate (311) with a tapered support block (311A), an elastic member (311B), a locking member (311C), and detachable magnets (311D), so that when the display (D) is mounted on the mounting device (100), the tapered mechanical coupling and magnetic force coupling are simultaneously formed, thereby stably supporting the display (D), and when detaching, the locking member (311C) is released and the magnetic force of the magnet is overcome to easily detach it, so that tasks such as replacement, cleaning, and maintenance of the display (D) can be easily performed.

[0251] In particular, the tapered mechanical coupling prevents the display (D) from moving in the front-back and left-right directions, the locking member (311C) prevents it from moving in the up-down direction, and the detachable magnets (311D) provide overall adhesion and stability, so that the three fixing methods are combined to provide an optimal detachable structure in which the display (D) is firmly fixed to the mounting device (100) while being easily detachable when necessary.

[0252] In addition, since the display (D) can be easily attached and detached, tasks such as charging the battery of the display (D), updating the software, or replacing it in case of failure can be performed quickly, thereby minimizing the downtime of the water purifier and greatly improving the convenience of maintenance.

[0253] According to an embodiment of the present invention, by separating the display (D) from the water purifier body (P) and providing rotation and angle adjustment functions, the user can clearly view the display screen from any direction, such as the front of the water purifier, as well as from the side and non-front positions, thereby ensuring visibility of water quality data and control screens even in confined spaces of laboratories and various installation environments.

[0254] In addition, by adopting a three-stage rotation structure consisting of a base module (1), a rotating module (2), and a pair of tilting modules (3), the circumferential rotation (left and right rotation) of the rotating module (2) and the circumferential rotation (up and down tilting) of the tilting module (3) can be combined to enable free angle adjustment in multiple axes, and accordingly, the display (D) can be positioned at an optimal angle to match the user's position and eye level.

[0255] In addition, by applying a double support structure (guide groove / sleeve and guide projection) to the base module (1) and the rotating module (2), the stability and durability of the rotational movement can be improved, and flow, shaking, eccentricity, and instability that may occur during rotation of the rotating module (2) and the tilting module (3) can be minimized to provide precise and balanced rotational movement.
