  The present invention relates to a powder discharger.

  2. Description of the Related Art Conventionally, a powder discharger that discharges powder together with air as shown in Patent Document 1 below is known.

JP 2008-295686 A

  By the way, this type of powder discharger has room for improvement in terms of simplification of configuration and improvement in operability.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a powder discharger that can be easily operated with a simple configuration.

  In order to solve the above problems, the powder discharger of the present invention has an air supply / exhaust chamber into which air is supplied / exhausted, an outside air introduction hole for introducing outside air into the air supply / exhaust chamber, and the air supply / exhaust chamber An elastically deformable discharger body having an exhaust hole for discharging the air, and allowing the air to flow into the supply / exhaust chamber through the outside air introduction hole and the supply through the outside air introduction hole An outside air introduction valve that regulates the outflow of air from the exhaust chamber, and a bottomed cylindrical storage that stores powder inside and that forms a communication path that communicates with the exhaust hole between the discharge body and the outside. A body, an exhaust valve that allows outflow of air from the air supply / exhaust chamber through the exhaust hole and restricts inflow of air into the air supply / exhaust chamber through the exhaust hole, and communicates with the reservoir In such a state that it can be raised relative to the reservoir, and the upper end opening is A discharge cylinder member configured to be an outlet hole and blocking communication between the storage body and the communication path, and when the discharge cylinder member rises with respect to the storage body, the storage body and the communication path It is characterized by communicating.

According to the powder discharger of the present invention, when the discharge cylinder member moves upward relative to the storage body, the storage body and the communication path communicate with each other. In this state, when the volume of the supply / exhaust chamber decreases due to the elastic deformation of the discharger main body, the internal pressure of the supply / exhaust chamber increases, so that the outside air introduction hole is blocked by the outside air introduction valve, and the air in the supply / exhaust chamber is It flows into the reservoir through the exhaust hole and the communication passage. Thereby, the powder stored in the storage body is rolled up by the air flowing into the storage body and discharged together with the air from the discharge hole. Also, when the volume of the supply / exhaust chamber increases due to the deformation of the discharger body, negative pressure is generated in the supply / exhaust chamber, the exhaust hole is blocked by the exhaust valve, and outside air is introduced into the supply / exhaust chamber from the outside air introduction hole. Is done.
As described above, the powder can be discharged from the discharge hole together with the air by an easy operation of elastically deforming the discharger body. In addition, since the communication path is formed by the reservoir and the discharger main body, the configuration of the powder discharger can be simplified as compared with the case where the communication path is formed by another member, for example.

  Here, the discharge cylinder member is formed with an inner cylinder portion defining a connection passage communicating with the storage body between an inner peripheral surface of the storage body and the discharge cylinder member with respect to the storage body. When the member rises, the communication passage and the connection passage may communicate with each other across the upper end opening edge of the reservoir.

In this case, since the connection passage communicating with both the communication passage and the storage body is formed by the inner peripheral surface of the storage body and the inner cylinder portion, the air passing through the connection passage is along the inner peripheral surface of the storage body. Fluid. As a result, the air that has passed through this connection passage flows so that the powder is pulled away from the inner peripheral surface of the reservoir, and the powder is wound up in a more uniformly dispersed state in the air and discharged from the discharge hole together with the air. Can be made. Furthermore, since the connection passage and the communication passage communicate with each other across the upper end opening edge of the reservoir, for example, when the powder discharger is inclined, it is difficult for powder to enter the communication passage through the connection passage. It is possible to suppress the back flow of the powder.
Further, by forming the connection passage having such a function by the inner cylinder portion and the reservoir of the discharge cylinder member without using another member, the configuration of the powder discharger can be simplified. .

  Moreover, the inner surface of the bottom of the reservoir may be formed in a curved surface that is convex downward.

  In this case, the air flowing into the reservoir is sprayed on the inner surface of the bottom of the reservoir formed in a convex curved shape downward, so that the powder in the reservoir is rolled up along the curved surface. In the state where air flows and the powder is more uniformly dispersed in the air, it can be discharged from the discharge holes together with the air.

  Moreover, the cap which interrupts | blocks the communication with the said discharge hole and the said storage body so that opening is possible may be attached to the said discharge cylinder member so that attachment or detachment is possible.

  In this case, the communication between the discharge hole and the communication path is doubly blocked by the cap that blocks the communication between the discharge hole and the storage body, and the discharge cylinder member that blocks the communication between the storage body and the communication path. Therefore, for example, when the powder discharger is transported or not used, it is possible to reliably prevent the discharge hole from communicating with the supply / exhaust chamber to prevent the powder from being discharged from the discharge hole.

The external fitting cylinder part 24 surrounds the fitting cylinder part 23 and the mouth part 11. On the inner peripheral surface of the outer fitting cylinder portion 24, a fitting portion 24 a that fits with the fitted portion 11 a formed on the outer peripheral surface of the mouth portion 11 is formed. The fitting part 24a is undercut fitted to the fitted part 11a. Thereby, when the discharge cylinder member 30 or the cap 40 is rotated, the connecting portion 20 is prevented from being detached from the main body portion 10. In addition, the relative rotation around the central axis O between the connecting portion 20 and the main body portion 10 may be restricted by a rotation stopper (not shown).

  The outer peripheral surface of the regulation cylinder part 25 contacts the inner peripheral surface of the main body 10 when the main body 10 is squeezed. Thereby, the regulation cylinder part 25 regulates the deformation amount of the main-body part 10 within a predetermined range. The lower cylinder portion 26 is disposed so as to penetrate the closing portion 21 in the vertical direction. The inner diameter of the lower cylinder portion 26 is smaller than the outer diameter of the reservoir 5. An exhaust hole 26a penetrating the bottom wall in the vertical direction is formed at a central portion in the radial direction of the bottom wall of the lower cylindrical portion 26.

The curved portion 27d is formed in a curved surface shape that protrudes outward in the radial direction. The lower end portion of the curved portion 27d is connected to the upper end portion of the lower cylinder portion 26.

The outside air introduction valve 3 is disposed in the supply / exhaust chamber S. The outside air introduction valve 3 is disposed below the closing portion 21 of the connecting portion 20 in the mouth portion 11 of the main body portion 10. The outside air introduction valve 3 allows air to flow into the supply / exhaust chamber S through the outside air introduction hole 22 and restricts the outflow of air from the supply / exhaust chamber S through the outside air introduction hole 22.
The outside air introduction valve 3 includes an attachment tube portion 3a that is fitted on the lower tube portion 26, and an introduction valve body 3b that extends from the upper portion of the attachment tube portion 3a toward the outside in the radial direction. The upper end portion of the attachment tube portion 3a is sandwiched in the radial direction by the lower tube portion 26 and the connection tube portion 27c of the connecting portion 20. The introduction valve main body 3b is formed in a plate shape that can be elastically deformed downward with respect to the mounting cylinder portion 3a. A thick part thicker than other parts of the introduction valve main body 3b is formed at the radially outer end of the introduction valve main body 3b, and this thick part comes into contact with the lower surface of the closing part 21. Yes. The introduction valve main body 3b is convexly curved downward. The length of the introduction valve main body 3b in the radial direction is larger than the inner diameter of the outside air introduction hole 22. The introduction valve main body 3 b closes the outside air introduction hole 22 from below the outside air introduction hole 22.

The exhaust valve 4 is disposed outside the supply / exhaust chamber S. The exhaust valve 4 is disposed at the bottom in the lower cylinder portion 26 of the connecting portion 20. The exhaust valve 4 allows the outflow of air from the supply / exhaust chamber S through the exhaust hole 26a and restricts the inflow of air into the supply / exhaust chamber S through the exhaust hole 26a.

The exhaust valve 4 includes an attachment tube portion 4a that fits in the lower tube portion 26, and an exhaust valve body 4b that extends radially inward from the lower end opening edge of the attachment tube portion 4a. The exhaust valve body 4b is formed in a disc shape that can be elastically displaced upward with respect to the mounting cylinder portion 4a. A part of the outer peripheral edge of the exhaust valve main body 4b is connected to the lower end opening edge of the mounting cylinder portion 4a. The outer diameter of the exhaust valve body 4b is larger than the inner diameter of the exhaust hole 26a. The exhaust valve body 4b closes the exhaust hole 26a from above the exhaust hole 26a. Of the exhaust valve body 4b, the central portion in the radial direction is thicker than the other portions.

The storage body 5 is disposed inside the storage cylinder portion 27. The storage body 5 is disposed at a position equivalent to the storage cylinder portion 27 in the vertical direction. In addition, the outer diameter of the reservoir 5 is smaller than the inner diameter of the accommodating cylinder portion 27. As a result, a communication passage S <b> 1 communicating with the exhaust hole 26 a is formed between the storage body 5 and the accommodating cylinder portion 27. The inner surface and the outer surface at the bottom of the reservoir 5 are each formed in a curved surface shape that protrudes downward. The outer surface at the bottom of the reservoir 5 and the inner surface of the curved portion 27d of the housing cylinder 27 are arranged concentrically in a longitudinal sectional view. Thereby, the lower part of communication path S1 is extended toward the inner side of radial direction as it goes below, maintaining the same flow path width in the longitudinal cross-sectional view along the central axis O.
The storage body 5 includes ribs 5 a extending from the peripheral wall portion and the bottom wall portion of the storage body 5 toward the outside of the storage body 5. The ribs 5a are formed in a cross shape extending outward in the radial direction with the central axis O as the center in a cross sectional view. The end surface on the outer side in the radial direction of the cross-shaped rib 5a comes into contact with the inner peripheral surfaces of the receiving cylinder part 27 and the lower cylinder part 26, so that the rib 5a is fitted in the receiving cylinder part 27 and the lower cylinder part 26. doing. Thereby, the storage body 5 is supported by the connection part 20. Further, when the discharge cylinder member 30 rises, the rise of the storage body 5 is restricted by a frictional force that acts between the inner cylinder portion 34 and the storage body 5 described later.

  The discharge cylinder member 30 includes a disk-shaped closing part 31 that closes the upper end opening of the housing cylinder part 27, an operation cylinder part 32 that extends downward from the outer peripheral edge of the closing part 31, and a lower side from the lower surface of the closing part 31. A sliding cylinder portion 33 and an inner cylinder portion 34 that extend toward the top, and a discharge cylinder portion 36 that extends upward from the closing portion 31. The central axes of the operation cylinder part 32, the sliding cylinder part 33, the inner cylinder part 34, and the discharge cylinder part 36 are arranged coaxially with the central axis O, respectively. The inner cylinder part 34 is disposed on the radially inner side of the sliding cylinder part 33, and the operation cylinder part 32 is disposed on the radially outer side of the sliding cylinder part 33.

  The blocking part 31 is in contact with or close to the upper end opening edge of the reservoir 5. On the inner peripheral surface of the operation tube portion 32, a female screw portion 32 a that is screwed with the male screw portion 27 a formed on the outer peripheral surface of the housing tube portion 27 is formed. The discharge cylinder member 30 is screwed to the connecting portion 20 by the male screw portion 27a and the female screw portion 32a being screwed together. Thereby, the discharge cylinder member 30 is disposed so as to be raised with respect to the storage body 5 in a state where the inside of the discharge cylinder portion 36 communicates with the storage body 5. Note that a knurled shape extending in the vertical direction may be formed on the outer peripheral surface of the operation cylinder portion 32 to prevent slipping.

  The lower end portion of the sliding cylinder portion 33 is located above the lower end portion of the inner cylinder portion 34 in the vertical direction. The outer diameter of the sliding cylinder portion 33 is formed to be equal to the inner diameter of the enlarged diameter portion 27 b of the accommodation cylinder portion 27. The outer peripheral surface of the sliding cylinder part 33 is in airtight contact with the inner peripheral surface of the enlarged diameter part 27 b of the accommodation cylinder part 27. When the discharge cylinder member 30 is rotated around the central axis O with respect to the connecting portion 20, the discharge cylinder member 30 is connected to the connecting portion while the sliding cylinder portion 33 and the enlarged diameter portion 27b of the accommodating cylinder portion 27 slide relative to each other. Rise to 20. Thereby, even after the discharge cylinder member 30 is raised, the occurrence of a gap between the sliding cylinder part 33 and the accommodating cylinder part 27 is suppressed, and the leakage of air from this gap is suppressed.

The inner cylinder part 34 has an inner peripheral surface continuous with an inner peripheral surface of the discharge cylinder part 36, and is disposed below the outer closed cylinder part 34a and an outer closed cylinder part 34a extending downward from the closed part 31. A reduced diameter portion 34b having an inner diameter and an outer diameter smaller than that of the closed cylinder portion 34a. The outer diameter of the reduced diameter portion 34 b is smaller than the inner diameter of the reservoir 5. Thereby, a connection passage S <b> 2 is defined between the outer peripheral surface of the reduced diameter portion 34 b and the inner peripheral surface of the reservoir 5. The outer peripheral surface of the outer closed cylinder 34 a is in close contact with the inner peripheral surface at the upper end of the reservoir 5. As a result, the outer closed cylinder portion 34a closes the upper portion of the connection passage S2.
The upper end opening of the discharge cylinder portion 36 is the discharge hole 30a described above. The inside of the discharge cylinder portion 36 communicates with the inside of the storage body 5 through the inside of the inner cylinder portion 34.

  The cap 40 is screwed (attached) to the upper portion of the discharge cylinder member 30 so as to be raised. The cap 40 closes the discharge hole 30a so as to be openable. The cap 40 has an inner closed cylindrical portion 43 that fits into and closes the reduced diameter portion 34 b of the inner cylindrical portion 34, and a bottomed cylindrical shape that extends upward from the upper end portion of the inner closed cylindrical portion 43. The connecting cylinder part 42, an annular flange part 41 extending radially outward from the upper end opening edge of the connecting cylinder part 42, and a cap cylinder part 44 extending upward and downward from the outer peripheral edge of the flange part 41. And are formed.

  The inner closed cylinder part 43 is formed radially inward from the outer closed cylinder part 34a. The inner closing cylinder part 43 and the outer closing cylinder part 34a doubly block communication between the discharge hole 30a and the communication path S1. The outer peripheral surface at the lower end portion of the inner closing cylinder portion 43 is gradually reduced in diameter as it goes downward. The connecting cylinder part 42 connects the inner closing cylinder part 43 and the flange part 41. The outer diameter of the connecting cylinder part 42 is larger than the outer diameter of the inner closing cylinder part 43 and smaller than the inner diameter of the discharge cylinder part 36. The lower surface of the flange portion 41 is in contact with the upper end opening edge of the discharge cylinder portion 36 and closes the discharge hole 30a. The inner diameter and outer diameter of the cap cylinder portion 44 are larger than the inner diameter and outer diameter of the connecting cylinder portion 42. The cap cylinder part 44 and the connecting cylinder part 42 sandwich the discharge cylinder part 36 in the radial direction. On the inner peripheral surface of the cap cylinder portion 44, a female screw portion 44a that is screwed with a male screw portion 36a formed on the outer peripheral surface of the discharge cylinder portion 36 is formed. The cap 40 is screwed to the discharge cylinder member 30 by screwing the female thread part 44 a of the cap cylinder part 44 and the male thread part 36 a of the discharge cylinder part 36. A knurled shape extending in the vertical direction may be formed on the outer peripheral surface of the cap cylinder portion 44 to prevent slipping.

  Next, the operation of the powder discharger 1 configured as described above will be described.

When the powder discharger 1 is used, first, the cap cylinder portion 44 of the cap 40 is picked and rotated with respect to the discharge cylinder member 30 around the central axis O. As a result, the cap 40 rises with respect to the discharge cylinder member 30, the flange portion 41 is separated from the upper end opening edge of the discharge cylinder portion 36, and the inner closing cylinder portion 43 is from the inside of the reduced diameter portion 34 b of the inner cylinder portion 34. Withdrawn, the discharge hole 30a and the inside of the reservoir 5 communicate with each other. When the cap 40 is further rotated, the cap 40 is removed from the discharge cylinder member 30.
Next, the operation cylinder part 32 of the discharge cylinder member 30 is picked, and the discharge cylinder member 30 is rotated around the central axis O with respect to the connection part 20 of the discharger body 2. Thereby, the discharge cylinder member 30 rises with respect to the connecting part 20, the closing part 31 is separated upward from the upper end opening edge of the reservoir 5 and the upper end opening edge of the connecting part 20, and the outer closing cylinder part 34 a is stored. It is extracted from the body 5 and the communication passage S1 and the connection passage S2 communicate with each other across the upper end opening edge of the storage body 5 (see FIG. 2).

  In this state, when the volume of the air supply / exhaust chamber S is decreased by elastically deforming (squeezing) the main body 10 of the discharger main body 2 to reduce the volume of the air supply / exhaust chamber S, the outside air introduction hole 22 is increased. Is closed by the outside air introduction valve 3, the exhaust valve body 4b of the exhaust valve 4 is elastically deformed or elastically displaced upward to release the exhaust hole 26a. The air in the supply / exhaust chamber S passes through the regulation cylinder 25, the exhaust hole 26a, the lower cylinder 26, the communication path S1, the upper opening edge of the reservoir 5 and the closing part 31, and the connection path S2. And sprayed toward the powder P in the reservoir 5. Thereby, the powder P is wound up by the blown air, moves up in the inner cylinder part 34 and the discharge cylinder part 36, and is discharged from the discharge hole 30a together with the air.

  Moreover, when the squeeze of the main body 10 is released, the main body 10 is restored and deformed, and the volume in the supply / exhaust chamber S is increased. As a result, a negative pressure is generated in the supply / exhaust chamber S, and the exhaust valve body 4b is elastically deformed or elastically displaced downward by this negative pressure to close the exhaust hole 26a. In addition, due to this negative pressure, the introduction valve body 3 b of the outside air introduction valve 3 is elastically deformed or elastically displaced downward to open the outside air introduction hole 22, and outside air is introduced into the supply / exhaust chamber S through the outside air introduction hole 22. .

As described above, the powder P can be discharged together with the air from the discharge hole 30a until the powder P in the storage body 5 disappears by an easy operation of repeatedly squeezing and opening the main body 10.
Further, since the communication path S1 is formed by the storage body 5 and the discharger body 2, for example, the configuration of the powder discharger 1 is simplified compared to the case where the communication path S1 is formed by another member. Can do.

In addition, since the connection passage S <b> 2 communicating with the inside of the storage body 5 is formed by the inner peripheral surface of the storage body 5 and the outer peripheral surface of the inner cylinder portion 34, the air passing through the connection passage S <b> 2 It flows along the inner peripheral surface. Thereby, the air that has passed through the connection passage S2 flows so as to separate the powder P from the inner peripheral surface of the storage body 5, and the powder P is wound up in a state of being more uniformly dispersed in the air, together with the air. It can be discharged from the discharge hole. Furthermore, since the connection passage S2 and the communication passage S1 communicate with each other across the upper end opening edge of the reservoir 5, for example, when the powder discharger 1 is tilted, the powder P communicates through the connection passage S2. It becomes possible to make it difficult to enter the passage S1, and the back flow of the powder can be suppressed.
Moreover, the connection passage S2 having such a function is formed by the inner cylinder portion 34 and the reservoir 5 of the discharge cylinder member 30 without using another member, thereby simplifying the configuration of the powder discharger 1. Can be achieved.

  Moreover, since the inner surface in the bottom part of the storage body 5 is formed in the convex curved surface shape toward the downward direction, the air which flows in the storage body 5 through the connection channel | path S2 is sprayed on this curved surface. The air flows so that the powder in the storage body 5 is rolled up along the curved surface, and the powder P can be discharged from the discharge holes 30a together with the air in a state of being more uniformly dispersed in the air. .

Further, the communication between the discharge hole 30a and the communication path S1 is a cap 40 that blocks communication between the discharge hole 30a and the inside of the storage body 5, and the discharge cylinder member 30 that blocks communication between the inside of the storage body 5 and the communication path S1. Therefore, for example, when the powder discharger 1 is transported or not in use, the discharge hole 30a and the supply / exhaust chamber S are unexpectedly communicated and the powder P is discharged from the discharge hole 30a. Can be surely prevented.
Further, since the closing portion 31 is in contact with or close to the upper end opening edge of the reservoir 5, the flow passage cross-sectional area of the connection portion between the communication passage S1 and the connection passage S2 is increased when the discharge cylinder member 30 is raised. It is possible to stabilize the flow velocity of the air sprayed onto the powder P while suppressing an excessive increase.

Further, when the main body portion 10 is elastically deformed, the inner peripheral surface of the main body portion 10 and the outer peripheral surface of the regulating cylinder portion 25 come into contact with each other, so that deformation of the main body portion 10 beyond a predetermined amount is suppressed. The discharge of the powder P from the hole 30a can be stabilized.
Moreover, since the inside of the storage body 5 and the exhaust hole 26a are obstruct | occluded by the exhaust valve 4, it can suppress that the powder P in the storage body 5 flows into the supply / exhaust chamber S unexpectedly.

Further, since the powder P is stored in the storage body 5 in which no hole or the like is formed in the bottom portion, for example, compared with a case where an air hole or the like is formed in the bottom portion of the storage body 5, for example, a cap When 40 or the like is removed, the powder P can be prevented from unexpectedly falling from the air hole at the bottom of the reservoir 5.
In addition, since the lower part of the communication passage S1 gradually extends toward the center in the radial direction as it goes downward while maintaining the same flow path width in a longitudinal sectional view, the air flowing out from the exhaust hole 26a is smoothly smoothed. Can be introduced into the communication path S1 and directed toward the powder P in the reservoir 5.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, when the cap 40 is rotated around the central axis O with respect to the connecting portion 20, the discharge cylinder member 30 rotates together with the cap 40 by a predetermined amount with respect to the connecting portion 20, and then the discharge cylinder member 30 is connected to the connecting portion 20. You may comprise so that rotation is controlled and only the cap 40 rotates with respect to the connection part 20. FIG. According to this configuration, the operation of rotating the cap 40 around the central axis O with respect to the connecting portion 20 makes it possible to raise the discharge cylinder member 30 while removing the cap 40, thereby improving operability. . As an example of such a configuration, while providing a first locking portion between the cap 40 and the discharge cylinder member 30 to prevent relative rotation of a predetermined amount or more around the central axis O of both members, Between the discharge cylinder member 30 and the connection part 20, you may provide the 2nd latching | locking part which controls relative rotation more than the predetermined amount around the center axis line O of both members. In this case, the first locking portion can be released by the relative rotation of the cap 40 and the discharge cylinder member 30 around the central axis O, and the second locking portion is the discharge cylinder member 30. The engagement may be unreleasable by relative rotation around the central axis O with the connecting portion 20.

Moreover, in the said embodiment, although the discharger main body 2 was comprised by the main-body part 10 and the connection part 20, it is not restricted to this, The discharger main body 2 with which the main-body part 10 and the connection part 20 were formed integrally. May be adopted.
Moreover, you may employ | adopt the discharger main body 2 which only a part of main-body part 10 can elastically deform. Alternatively, an elastically deformable member may be attached to the main body unit 10.

  Alternatively, the discharge cylinder member 30 may be formed so as to be detachable with respect to the connecting portion 20 so that the storage body 5 can be replaced after the discharge cylinder member 30 is detached from the connecting portion 20. Accordingly, for example, by using the storage body 5 as a refill part and replacing the empty storage body 5 with the storage body 5 filled with the powder P, the powder discharger 1 can be used repeatedly. it can.

Moreover, in the said embodiment, although the connection channel | path S2 was formed of the inner cylinder part 34 and the storage body 5, you may employ | adopt the powder discharger 1 which is not provided with such a connection channel | path S2.
