Description

Technical Field

[0001] The present invention relates to a chemical supply device, and more particularly to a chemical supply device for supplying fluid. Background Art

[0002] Generally speaking, companies that manufacture semiconductors, semiconductor devices, LCDs, OLEDs, and all companies that use hazardous chemicals, such as pharmaceutical companies and paint companies, use a variety of chemicals. In particular, in the semiconductor device manufacturing process, etc., a very large number of processes are performed, and each process uses a variety of chemical substances. However, these chemicals must have very correct conditions, such as the correct concentration, mixing ratio, temperature, acidity, etc.

[0003] For example, a titrator used in semiconductor equipment to measure the concentration of a chemical substance is equipped with a titrator reagent reservoir. The titrator is a device that always prepares several reagents and supplies the required reagents according to the appropriate object. The titration operation itself usually requires a very precise supply of reagents. If the amount or type of the reagent is wrong, very big problems will occur. Therefore, it is crucial to supply the correct type of reagent in the correct amount.

[0004] As such, in order to always satisfy the titration conditions of various types of chemical substances and smoothly supply the substances to the required processes or devices under the correct conditions and at the right time, a supply device is required that prepares the corresponding various chemicals in the process equipment or device and supplies them whenever needed. For example, in a chemical concentration monitoring device associated with a specific chemical tank, the concentration of the corresponding chemical can be monitored by a sensor, and several component chemicals for adjusting the chemical conditions can be supplied as needed, and test chemicals for chemical titration can also be supplied to the monitoring device.

[0005] However, in a chemical supply device loaded with multiple chemicals, not all chemicals need to be supplied, used, replenished, or replaced at the same time. For example, the usage of each chemical may vary, so the supply device needs to keep track of the types of chemicals that are prone to shortages and be prepared to supply them in a timely manner. Unless the usage is extremely large, the method used in most cases is to prepare a chemical container of a certain capacity and replace the chemical container itself to replenish the insufficient amount of chemicals.

[0006] The methods of safely supplying these chemicals are also diversifying. For this reason, the existing chemical supply system is composed of a structure for supplying chemicals from multiple chemical containers, wherein a discharge pipe is connected by opening and closing a cover of the chemical container inlet, and a discharge pump is connected to the discharge pipe, so that the operation of the discharge pump sucks the chemicals inside the chemical container and supplies them to the use site through the discharge pipe.

[0007] However, in this type of chemical supply system, when the chemical in one container is exhausted, a container of the same shape filled with the chemical is prepared and replaced with the empty container at the corresponding position and used.

[0008] To this end, the following operations are usually completed: first, the lid of a new container filled with chemicals is opened, and on the other hand, the lid of an exhausted container at the corresponding position is opened, the exhausted container is taken out from the corresponding position, a new container is placed at the corresponding position, and the lid with a discharge pipe is combined with the new container.

[0009] However, in the existing chemical supply system, since the containers have the same shape and size, there may be a problem that the type of chemical to be replaced is confused and a container containing a different chemical is replaced or substituted at an inappropriate location.

[0010] Although chemicals are marked by type on containers to prevent this, there is still the possibility that errors may be made due to carelessness of operators.

[0011] In particular, in semiconductor device manufacturing processes or titration equipment that require precise processes, such chemical mix-ups may have fatal consequences for the process or the chemical supply equipment.

[0012] Therefore, the operator must concentrate on preventing such erroneous replacement from occurring. However, since mistakes can always occur in human operations, a plurality of chemical supply devices having a structure that can eliminate such erroneous replacement problems from the source are required.

[0013] On the one hand, the existing chemical supply system is set up in a way that the end of the discharge pipe inserted into the container is lowered to the bottom of the container, but this will cause a slight gap, making it difficult to use up all the chemicals covering the bottom of the container, and chemical residues will repeatedly occur during replacement. On the other hand, if there is no residue, it is in a state where chemicals cannot be supplied, so replacement is usually accompanied by process interruption.

[0014] Furthermore, when replacing the container, the discharge pipe is separated from the container together with the cover, so that the chemical cannot be supplied. In cases where a process needs to be performed continuously, the process is interrupted when the chemical is replenished or replaced. This may cause many problems. In order to prevent this, there is a problem that the connection of the supply pipeline becomes complicated and the equipment cost increases.

[0015] Furthermore, when performing operations, it may not be possible to ensure sufficient working space due to the surrounding environment, and depending on the specific shape of the replacement structure, the possibility of chemicals leaking out and contaminating the surroundings or substances harmful to the health of the workers sticking to or splashing on the workers, thereby destroying the working environment and damaging the health of the workers, will increase.

[0016] That is, since the process of separating the cap from the container and connecting the connector to the fluid line is performed manually by the operator, there is a high risk that the operator is exposed to harmful chemicals during the operation and a safety accident may occur.

[0017] Also, in the process of replacing an exhausted container with a new container, when the discharge pipe attached to the cap is exposed to the outside of the container, there is a possibility that the chemical filled in or adhered to the discharge pipe may fall or splash around.

[0018] Therefore, not only the chemical in the discharge pipe leaks, but also air enters the discharge pipe, and even after the container is replaced, this air continues to remain and generates bubbles in the chemical supply line, and the chemical may be supplied in the process with these bubbles, causing process problems. That is, it may cause data stability problems. Summary of the invention

[0023] Furthermore, an object of the present invention is to provide a chemical supply device which can replace a chemical supply container without interrupting the chemical supply.

[0025] The chemical supply device of the present invention for achieving the above-mentioned purpose includes: a bottle body, which stores the supply fluid inside and is formed with a discharge port on the lower side; a liquid reservoir, which is formed with an inlet on the upper side that is fluidly connected to the discharge port to receive the supply fluid and is formed with an outlet on one side to provide the supply fluid to the outside; a joint assembly, which is arranged between the bottle body and the liquid reservoir and has a mutual identification structure for controlling the physical combination of the bottle body and the liquid reservoir; and a guide shell, which can detachably store the bottle body and is used to support the bottle body and the liquid reservoir connected by the joint assembly in a connected state.

The guide housing holds the liquid reservoir and the bottle stored in each mounting portion at a certain interval.

[0027] According to this embodiment, the shell body includes: a bottom plate, which is set on the ground; and a plurality of vertical plates, which are uprightly arranged on both sides of the bottom plate and opposite to each other, so as to limit the lateral movement of the bottle body and the liquid reservoir.

[0029] According to this embodiment, the shell body part further includes an auxiliary support member, which is formed to protrude and be spaced apart from the support plate on the other side of the vertical plate and is used to support the lower side of the bottle body.

[0030] The support plate and the auxiliary support member are characterized in that their upper sides are formed in a downwardly inclined manner toward each other, that is, the support plate and the auxiliary support member are arranged in a downwardly inclined manner toward the discharge port formed at the lower part of the bottle body.

[0031] According to this embodiment, the bottle body includes a protruding block, which is protrudingly arranged on at least one side of the bottle body supported by the vertical plate. Correspondingly, the vertical plate includes an insertion groove, which is formed in a manner of opening the upper side so that the protruding block can be inserted therein.

[0032] According to this embodiment, the vertical plate is characterized in that its upper side has a path with a specified curvature so as to provide a sliding guide surface, which enables the protruding block provided on the bottle body to move to the position of the insertion groove while being placed on the upper side of the vertical plate adjacent to the other side end.

[0033] According to this embodiment, the shell body part further includes a stopper, which is protrudingly arranged on the inner side surface of the vertical plate, so as to prevent the liquid reservoir inserted from the other side of the second mounting part from being disengaged from one side.

Therefore, the present invention can provide convenience for replacement work by simplifying the replacement work.

[0041] Furthermore, the present invention can prevent problems such as process interruption due to the continuous supply of multiple chemicals when the upper container and the lower container are connected for replenishment or replacement operations, and by placing them respectively at the upper and lower parts, all residual amounts can be reused during replacement, thereby having the advantage of reducing production costs.

[0052] Advantages and features of the present invention and methods of achieving them will become clear with reference to the following embodiments described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various forms different from each other.

[0053] Hereinafter, the technical features of the present invention will be described in detail with reference to the accompanying drawings.

[0054] Reference Figures 1 to 4 According to an embodiment of the present invention, a chemical supply device may include a bottle body 110 , a liquid reservoir 120 , a joint assembly 130 and a guide housing 140 .

[0055] like Figure 1 As shown, the chemical supply device of the present invention can be configured as a single structure for supplying one type of chemical, but can also be configured as a plurality of structures. Figure 3 As shown, the chemical supply device can be respectively provided as a plurality of structures that are distinguished into a first supply part 100 and a second supply part 200, and the first supply part 100 and the second supply part 200 can be respectively provided on a base. When the chemical supply device composed of a plurality of structures is provided by two or more structures, it can be used to supply one type of chemical from each supply part 100, 200 to increase the total capacity stored in the liquid reservoir, or to accommodate different types of chemicals in each supply part 100, 200 to supply multiple chemicals. These supply parts 100, 200 are respectively composed of respective bottles, liquid reservoirs, joint components and guide shells.

[0056] According to the present embodiment, the bottle 110 can be provided as a first container 111, which is configured to store a supply fluid therein. The supply fluid refers to a fluid such as a reagent or a chemical, and a certain amount is stored in the bottle 110. The bottle 110 is formed with an open hole-shaped discharge port 111a on the lower side, and the fluid stored inside can be discharged to the outside through the discharge port 111a. The discharge port 111a is provided with a discharge adapter 113 to ensure smooth fluid supply. This will be described later.

[0057] According to the present embodiment, the liquid reservoir 120 may be provided as a second container 121, which is formed in a manner that a certain amount of fluid can be contained. The liquid reservoir 120 may be disposed at the lower portion of the bottle body 110 and connected to the bottle body 110. Therefore, the liquid reservoir 120 may receive the fluid contained in the bottle body 110. To this end, the liquid reservoir 120 may form an inlet 121a fluidly connected to the discharge port 111a on the upper side of the second container 121 and may receive the supply fluid.

[0058] The inlet 121a may be provided in the shape of a hole opened in the liquid reservoir 120 so as to be directly or indirectly connected to the discharge port 111a. The inlet 121a is provided with an inlet adapter 123 that can be combined with the discharge adapter 113, thereby ensuring smooth fluid supply. Therefore, the fluid contained in the bottle body 110 falls by gravity and flows into the liquid reservoir 120.

[0059] The connection structure of the discharge adapter 113 and the inflow adapter 123 for direct fluid transfer between the bottle body 110 and the reservoir 120 can be set in an open and close manner.

[0060] For example, each adapter is provided in a socket and plug combination structure. The discharge adapter 113 may be in the form of a connection plug, and the inflow adapter 123 may be in the form of a connection socket into which the discharge adapter 113 can be inserted.

[0061] The discharge adapter 113 includes a first housing 113 a , a first moving member 113 b , and a first body 113 c , and the first moving member 113 b contacts the moving member of the inflow adapter 123 and forms a flow path that can communicate with each other in the body portion.

[0062] Similarly, the inflow adapter 123 includes a second housing 123a, a second moving member 123b and a second body 123c, and forms a flow path for fluid flow as the second moving member 123b moves. That is, the channels forming each flow path are opened and closed by the movement of the moving member.

[0063] Due to the valve-type coupling structure of the adapter, the fluid in the bottle 110 can move to the liquid reservoir 120 .

[0064] In addition, the liquid reservoir 120 may be provided in a manner that an outlet 122 is formed on one side of the second container 121 to provide the supply fluid to the outside. The outside refers to a device that receives the fluid from the chemical supply device of the present invention. At least one connecting pipe may be connected to the outlet 122. That is, the liquid reservoir 120 may discharge the fluid to a device or pipeline that uses the fluid through the outlet 122 connected to the outside.

[0065] In addition, the reservoir 120 may be provided with a reservoir cover 126 that performs an exhaust function at the upper portion, and the reservoir cover 126 may control the smooth flow of the fluid through the exhaust function. For example, the reservoir cover 126 may be coupled to an exhaust port 125 protruding from the upper portion of the reservoir 120, and an exhaust cover 127 that allows air to pass while preventing the fluid from being discharged to the outside may be provided therebetween. Furthermore, an exhaust assembly 128 is provided on the exhaust cover 127, and an exhaust pipe 129 is connected to the end of the exhaust assembly 128, so that the exhaust line can be supplied. Even if more than a certain amount of fluid is stored inside the reservoir 120, the exhaust structure can prevent overflow, and the internal air pressure difference of the reservoir 120 is maintained by allowing air to pass, so that the fluidity of the fluid flowing into the reservoir 120 can be smoothly induced.

[0066] At this time, the bottle body 110 and the liquid storage container 120 of the present invention are respectively arranged at the upper part and the lower part by the guide housing 140 described later, so that the fluid can be transported in the vertical direction.

[0067] In this configuration, the reservoir 120 is located at the lower portion, and the bottle body 110 connected to the reservoir 120 is located at the upper portion, so that the fluid can naturally move from the bottle body 110 to the reservoir 120 by gravity. The discharge port 111a is provided at the lower portion of the bottle body 110, so that virtually all of the fluid can be delivered to the reservoir 120 without a residual amount, and the reservoir 120 can hold a certain amount of fluid, so that even when the bottle body 110 is in an empty state and the bottle body 110 is separated from the reservoir 120, the fluid in the reservoir 120 can be continuously supplied to a desired location for a considerable period of time through the discharge pipe connected to the outlet 122.

[0068] According to the present embodiment, the joint assembly 130 is disposed between the bottle body 110 and the liquid reservoir 120 , so that a mutual recognition structure for controlling the physical connection between the bottle body 110 and the liquid reservoir 120 can be provided.

[0069] Among them, according to this embodiment, the bottle body 110 and the liquid reservoir 120 are respectively arranged at the upper part and the lower part, so that the discharge port 111a and the inlet 121a are directly connected in the up-down direction, and a separate pipeline-type connecting pipe is not used, so there is a limitation in preventing the operator from mistakenly connecting the bottle body containing different types of fluids to the liquid reservoir. Therefore, the joint assembly 130 of the present invention controls the physical connection through a mutual recognition structure.

[0070] That is, the present invention allows physical connection only in the case of the same fluid by the joint assembly 130, and prevents the combination of bottles containing different types of fluids in advance by limiting the physical connection in the case of different types of fluids, thereby minimizing mixing accidents caused by incorrect combination.

[0071] In addition, according to this embodiment, the joint assembly 130 may include a first identification portion 130a disposed on the bottle body 110 and a second identification portion 130b disposed on the liquid reservoir 120. Figures 5 to 8 The structure of the joint assembly 130 will be described in more detail.

[0072] The first identification part 130a located on the bottle body 110 side may be provided at the lower portion of the first container 111 and may be disposed at a position spaced apart from the discharge port 111a. A hole-shaped identification coupling groove 131a is formed on the first identification part 130a.

[0073] The identification and coupling groove 131a may be formed in a manner having a preset position according to the type of the supply fluid stored in the bottle 110. That is, the identification and coupling groove 131a is set in a manner that can be selectively changed to different positions according to the type of the fluid, and the preset position information may be included in the production process of the bottle 110 storing the supply fluid or may be set in advance when the fluid is provided to the device that uses the fluid. That is, when the supply fluid is supplied to the inside of the bottle 110 in a stored state, the selected position of the identification and coupling groove 131a is fixed.

[0074] To this end, the first identification portion 130 a may include: a first dial 131 having an identification coupling groove 131 a formed thereon; and a first body 114 which is a portion coupled to the first dial 131 and is formed on the first container 111 .

[0075] The first dial 131 may be formed of a substantially disc-shaped component, and may be arranged in a manner that is concentrically rotatable relative to the first body 114 by forming a protrusion-shaped rotating shaft (not shown) at the center portion. The first dial 131 changes the position of the identification coupling groove 131a as the first dial 131 is rotated. At this time, the first dial 131 may be fixedly arranged on the first body 114 by pin coupling or thread coupling. As shown in the figure, the first dial 131 includes a first pin coupling groove 131b, which is formed at a position opposite to the identification coupling groove 131a. A first fixing component B is inserted through the first pin coupling groove 131b, and the first fixing component B is provided in the form of an insertion pin or a screw, and the first fixing component B is coupled to the first body 114 while fixing the first dial 131.

[0076] The first body 114 can be integrally formed at the lower part of the first container 111, and a first rotating shaft groove 114a is formed in the center thereof, the rotating shaft of the first dial 131 is coupled to the first rotating shaft groove 114a, and a plurality of first fastening grooves 114b are arranged in a circle with the center as the axis, and the plurality of first fastening grooves 114b are used to couple with a first fixing component B set on the first dial 131.

[0077] As such, when the first dial 131 is rotatably arranged relative to the first body 114, the first identification portion 130a can adjust the position of the identification coupling groove 131a according to the type of the supply fluid. That is, the identification coupling groove 131a can change the preset position according to the type of the supply fluid stored inside the container. However, when the fluid stored or stored in the bottle body 110 is determined, the position of the identification coupling groove 131a can only be set at the preset position in a fixed state, and in order to perform initial setting, it is used with a structure that can change the position.

[0078] On the other hand, the second identification part 130b located on the side of the reservoir 120 may be provided at the upper portion of the second container 121. The second identification part 130b may be provided at a position spaced apart from the inlet 121a, and may include an identification combination key 135 protrudingly provided so as to be inserted into the identification engagement groove 131a.

[0079] The identification key 135 can be configured to be positionally changeable so as to correspond to the set position of the identification groove 131a of the first identification portion 130a. That is, the identification key 135 can be selectively changed to different positions according to the type of supply fluid provided by the bottle 110.

[0080] To this end, the second identification portion 130b may include: a second dial 133, on which an identification combination key 135 is provided; and a second body 124, which is a portion to which the second dial 133 is combined and is formed on the second container 121. Except that the second body 124 is integrally formed with the liquid reservoir 120, the second identification portion 130b may be formed similarly to the overall structure of the first identification portion 130a.

[0081] The second dial 133 may be a disc-shaped component having a shape corresponding to the first dial 131, and a rotation axis is formed protruding from the center so as to be rotatable relative to the second body 124. The second dial 133 may change the setting position of the identification combination key 135 by a rotation operation, and is formed with a key slot 133a for setting the identification combination key 135, and a second pin coupling slot 135b is provided at a position opposite to the key slot 133a, wherein the second fixing component B is inserted through the second pin coupling slot 135b. Therefore, the second dial 133 may be fixedly provided to the second body 124 through the second fixing component B.

[0082] The second body 124 can be integrally formed at the lower portion of the second container 121, and a second rotation axis groove 124a is formed at its center, the rotation axis of the second dial 133 is coupled to the second rotation axis groove 124a, and a plurality of second fastening grooves 124b are arranged in a circle with the second rotation axis groove 124a as the center axis.

[0083] As such, the second identification portion 130b has a structure capable of changing the position of the identification binding key 135 to a position corresponding to the identification binding groove 131a by the rotation of the second dial 133 relative to the second body 124, thereby providing a structure capable of setting the position of the identification binding key 135 to a preset position according to the fluid used. Therefore, the second identification portion 130b allows the bottle body 110 and the liquid reservoir 120 to be combined by enabling the identification binding key 135 to be inserted into the identification binding groove 131a.

[0084] On the contrary, when the bottle body stores a fluid different from the fluid used by the chemical supply device of this embodiment and has a different set position, the joint assembly 130 of the mutual recognition structure will be restricted from physical combination due to the different positions of the first identification part 130a and the second identification part 130b, thereby preventing erroneous combination and blocking the supply of different fluids in advance.

[0085] As such, the joint assembly 130 according to the present embodiment is provided as a structure of a first dial 131 arranged on the bottle body 110 and a second dial 133 arranged on the liquid reservoir 120, and the physical combination of the bottle body 110 and the liquid reservoir 120 can be controlled by the corresponding structures of the identification combination groove 131a and the identification combination key 135 arranged on each dial.

[0086] That is, the joint assembly 130 can normally connect the bottle body 110 to the liquid reservoir 120 according to whether the positions of the identification coupling groove 131a and the identification coupling key 135 match. Therefore, in the case where the position of the identification coupling groove 131a and the position of the identification coupling key 135 are different from each other, the bottle body 110 and the liquid reservoir 120 can be prevented from being physically coupled.

[0087] Finally, in the chemical supply device of the present invention, when the fluid type provided for injection does not match, the key connection positions of the joint assembly 130 provided in the bottle body 110 and the liquid reservoir 120 are different, so that the bottle body 110 cannot be connected to the liquid reservoir 120 by restricting the physical connection, and only when the fluid type matches, the key connection positions of the provided joint assembly 130 will correspond, so that the bottle body 110 can be smoothly connected to the liquid reservoir 120.

[0088] Therefore, according to the chemical supply device of an embodiment of the present invention, for the bottle 110 storing a fluid different from the fluid to be injected into the reservoir 120 provided in the guide housing 140, erroneous injection of the fluid can be prevented by limiting the physical combination through the joint assembly 130.

[0089] On the other hand, in the connector assembly 130 of the present invention, at the position corresponding to each key code indicating each reagent code, the code marking part 114c, 124c for identification is formed on each body or dial. For example, the code marking part 114c, 124c can be in the code of the form of color or symbol (word or number) in the part adjacent to each hole of the setting position of the identification combination groove 131a and the identification combination key 135. For example, a colored sticker representing each key code can be pasted or can be marked in the form of engraved letters or numbers. With reference to the accompanying drawings, it can be confirmed that each key code is marked at the position spaced apart from the concentric outer side of the circular arrangement of the identification combination groove 131a and the identification combination key 135 on the surface of the first body 114 and the second body 124. Therefore, the code marking part 114c, 124c can confirm the color or symbol matching or mismatching state by the naked eye, so the key code can be easily identified before physical combination, and then the type of reagent can be easily grasped.

[0090] Furthermore, the joint assembly 130 may further include position marking portions 131c and 133c. The position marking portions 131c and 133c are provided as arrow marks indicating the positions of the identification coupling groove 131a and the identification coupling key 135, thereby improving the understanding of the corresponding key code by naked eyes.

[0091] According to the present embodiment, the guide housing 140 serves to detachably store the bottle body 110 and the liquid reservoir 120 , and to support the bottle 110 and the liquid reservoir 120 connected by the joint assembly 130 in a connected state.

[0092] The guide housing 140 may include a housing body 140 , a first mounting portion 140 a , and a second mounting portion 140 b .

[0093] The case body portion 140 provides a frame structure for stably supporting the bottle body 110 and the liquid reservoir 120 .

[0094] The first mounting portion 140 a is formed in an open manner on the upper side of the case body 140 to define and form a mounting space for the bottle body 110 .

[0095] The second mounting portion 140b may be located at the lower side of the housing body 140, and the other side may be formed open to define and form a mounting space for the liquid reservoir 120. The second mounting portion 140b is spaced apart from the lower portion of the first mounting portion 140a, so that the bottle body 110 and the liquid reservoir 120 can maintain a vertical combination structure (upper and lower combination).

[0096] The guide housing 140 holds the bottle 110 and the liquid reservoir 120 stored in the respective mounting portions 140 a and 140 b at a predetermined interval.

[0097] The detailed configuration of the guide housing 140 will be described later.

[0098] The chemical supply device 100 of the present invention constructed as described above places the bottle 110 and the liquid reservoir 120 on the guide housing 140 , respectively, and connects them in a communicable manner, so that the reagent in the bottle 110 can be poured into the liquid reservoir 120 .

[0099] As such, in the chemical supply device 100 according to an embodiment of the present invention, the bottle body 110 is located at the upper part, and the liquid reservoir 120 connected to the bottle body 110 is located at the lower part, so that the internal fluid can be moved from the upper side to the lower side by gravity.

[0100] At this time, the chemical supply device 100 of the present invention has the following advantages: a discharge port 111a is provided on the lower side of the bottle body 110, so that the fluid stored in the bottle body 110 can be transported to the liquid reservoir 120 without any residual amount, and the liquid reservoir 120 contains a certain amount of fluid, so even when the bottle body 110 is in an empty state and the bottle body 110 needs to be separated from the liquid reservoir 120 and the guide shell 140, the remaining fluid contained in the liquid reservoir 120 can be continuously supplied to the desired place.

[0101] Fig. 9 and Fig.10 FIG. 1 schematically shows a perspective view and a cross-sectional view of a guide housing 140 according to an embodiment of the present invention. Fig. 9 and Fig.10 The structure of the guide housing 140 will be described in detail.

[0102] According to the present embodiment, the shell body 140 includes: a bottom plate 141 disposed on the ground; and a plurality of vertical plates 142 , 143 , which are uprightly disposed on both sides of the bottom plate 141 and are opposite to each other.

[0103] The bottom plate 141 may be formed of a substantially rectangular plate having a length extending to one side and the other side, and the reservoir 120 is disposed on an upper surface thereof.

[0104] A plurality of vertical plates 142 , 143 are respectively disposed on both sides of the bottom plate 141 in a width direction intersecting the length direction, thereby limiting lateral movement of the bottle body 110 and the liquid reservoir 120 .

[0105] The shell body 140 according to this embodiment further includes a support plate 144 , which is arranged on one side of the vertical plates 142 , 143 in a manner of spanning between the vertical plates 142 , 143 , so as to support the lower side of the bottle body 110 .

[0106] The support plate 144 may be provided as a plate-shaped member and disposed in a manner corresponding to a portion of a lower side surface of the first container 111 , thereby stably supporting the first container 111 .

[0107] In addition, the case body 140 according to the present embodiment further includes an auxiliary support member 145 protrudingly formed at the other side of the vertical plates 142 , 143 at a position spaced apart from the support plate 144 , so as to support the lower side of the bottle body 110 .

[0108] The auxiliary support member 145 is disposed at a position opposite to the support plate 144 in a manner corresponding to the other side portion of the lower side of the first container 111 , thereby stably supporting the first container 111 together with the support plate 144 .

[0109] The support plate 144 and the auxiliary support member 145 are characterized in that their upper sides are formed in a downwardly inclined manner toward each other. That is, the support plate 144 and the auxiliary support member 145 can be configured in a downwardly inclined manner toward the discharge port 111a formed at the lower part of the bottle body 110.

[0110] In addition, their tilted structures are related to the shape characteristics of the bottle body 110. As shown in the figure, the bottle body 110 according to this embodiment has a shape in which the lower part of the first container 111 tilts downward from both sides toward the discharge port 111a. Therefore, the bottle body 110 can discharge all the supply fluid stored inside.

[0111] Due to the shape of the bottle body 110 , the support plate 144 and the auxiliary support member 145 of the present embodiment have a structure in which they are arranged tilted in accordance with the shape of the lower portion of the bottle body 110 .

[0112] Therefore, the support plate 144 and the auxiliary support member 145 are formed in a shape corresponding to the bottle body 110, so that not only the bottle body 110 can be firmly supported, but also a stable supporting force for the bottle body 110 can be ensured due to the V-shaped configuration structure.

[0113] Furthermore, according to the present embodiment, the bottle body 110 may include a protruding block 115 .

[0114] The protruding block 115 may be protrudingly disposed on at least one side of the first container 111 supported by the vertical plates 142 and 143. For example, the protruding block 115 is protrudingly disposed on both sides of the first container 111 in a square shape.

[0115] At this time, correspondingly, the vertical plates 142 and 143 include insertion grooves 142 a and 143 a formed in such a manner that the upper sides thereof are opened so that the protruding blocks 115 can be inserted therein.

[0116] The insertion grooves 142a and 143a may be recessed grooves corresponding to the shape of the protruding block 115 so that the protruding block 115 can be inserted therein. That is, the insertion grooves 142a and 143a are formed inwardly at positions corresponding to the protruding blocks 115 on the upper sides of the vertical plates 142 and 143.

[0117] When the bottle body 110 is coupled to the guide housing 140, the insertion grooves 142a and 143a allow the protruding block 115 to be inserted therein, thereby maintaining a stable coupled state. In particular, the protruding block 115 and the insertion grooves 142a and 143a have a structure supported on at least three sides due to their square shape, thereby limiting the bottle body 110 from moving to one side and the other side and from moving downward excessively. As such, the present invention provides a stable coupled structure.

[0118] In addition, according to the present embodiment, the vertical plates 142 and 143 may include sliding guide surfaces 142b and 143b. The sliding guide surfaces 142b and 143b are provided as guide surfaces that enable the protruding block 115 provided on the bottle body 110 to move to the position of the insertion grooves 142a and 143a in a state where the protruding block 115 is arranged on the upper side adjacent to the other side end. For this purpose, the vertical plates 142 and 143 may be provided in the shape of a path having a prescribed curvature on the upper side.

[0119] like Fig.11 As shown, the sliding guide surfaces 142b and 143b can perform a guiding function in the operation of combining the bottle body 110 and the liquid reservoir 120, thereby ensuring the convenience of use of the combination structure using the protruding block 115.

[0120] Further, according to this embodiment, the shell body 140 also includes a stopper 146, which is protrudingly arranged on the inner side of the vertical plates 142 and 143, so as to prevent the liquid reservoir 120 inserted from the other side of the second mounting portion 140b from detaching from one side.

[0121] The stopper 146 is provided on the inner side of the vertical plates 142 and 143 in the form of a block-shaped protrusion, thereby limiting the movement of the second container 121 in a lateral direction.

[0122] The vertical plates 142 and 143 may be provided with an insertion hole 148, which is provided at a position opposite to the stopper 146 and is used to fasten the coupling protrusion 121b protruding from the other end of the second container 121, and may be extended to form a guide groove 149, which guides the coupling protrusion 121b to enter the insertion hole 148. Thus, the liquid reservoir 120 can be kept in a stable fixed state.

[0123] On the other hand, according to this embodiment, the shell body 140 also includes a first pressing member 147, which is protruding from the inner side surface of the vertical plates 142 and 143 at a position spaced apart from the stop member 146, so as to support the upper side surface of the liquid reservoir 120.

[0124] The first pressing member 147 is arranged at a predetermined height from the bottom plate 141 and limits the height direction interval to a certain distance, so that when the second container 121 is slidably inserted into the second mounting portion 140b, a space is provided in the form of being pressed by the first pressing member 147. That is, the first pressing member 147 allows the second container 121 to be installed in the guide housing 140 in an insertion manner, thereby being stably supported by the guide housing 140.

[0125] The housing body 140 further includes a second pressing member 146a extending horizontally from the stopper 146 to support the upper side of the reservoir 120. The second pressing member 146a is spaced apart from the first pressing member 147 to support the reservoir 120 more stably.

[0126] As such, the guide housing 140 may place the bottle body 110 and the liquid reservoir 120 in a spaced-apart state.

[0127] As such, the chemical supply device 100 according to an embodiment of the present invention can provide a structure that restricts or allows physical coupling by the joint assembly 130 that provides a mutual recognition structure, thereby preventing erroneous injection of fluid due to accidental coupling.

[0128] Also, the chemical supply device according to an embodiment of the present invention can simply perform mounting and detaching operations of the bottle body 110 by the guide housing 140 .

[0129] In particular, the chemical supply device of the present invention has a vertically coupled docking structure, so that the bottle body 110 and the liquid reservoir 120 can maintain a stable coupled state.

[0130] Further, the present invention can smoothly move the fluid by guiding the housing 140 through the stably fixed and pressurized structure of the container.

[0131] Furthermore, the present invention has a structure for preventing bubbles from being generated during a replacement operation or a charging operation, thereby improving data stability.

[0132] To this end, a tube (not shown) having an I-shaped or L-shaped pipe may be connected to the inflow adapter 123 so that the fluid can be discharged from the bottom side of the reservoir 120. That is, the tube can also minimize bubbles generated by dripping at the end of the inflow adapter 123.

[0133] At this time, the tube may be formed into an L-shaped pipe, and by discharging the fluid to the side opposite to the outlet, even if bubbles are generated, the discharge through the outlet can be minimized.

[0134] Furthermore, the present invention can detect the residual amount through the sensor and identify the replacement time, thereby preventing the interruption of reagent supply due to insufficient reagent.

[0135] To this end, preferably, a plurality of sensors (not shown) are attached to the chemical supply device according to the present embodiment so that it can be controlled by an externally connected monitoring system (not shown). The sensors may include a water level measuring sensor for measuring the liquid level of the reagent, a bubble sensing sensor for sensing the generation of bubbles, and an outflow sensing sensor for sensing the outflow site.

[0136] Furthermore, the chemical supply device 100 according to an embodiment of the present invention can easily connect the bottle 110 to the liquid reservoir 120 through an adapter formed by a valve structure, and prevent the chemicals from being discharged arbitrarily through the valve structure, thereby minimizing the problem of chemical leakage during replacement.

Therefore, the embodiments disclosed in the present invention are for illustration rather than for limiting the technical idea of ​​the present invention, and the scope of the technical idea of ​​the present invention is not limited by these embodiments.
