Description

TECHNICAL FIELD

[0001] The present application relates to a kind of quantitative discharging device, in particular a kind of quantitative discharging device and storage container for quantitative output material. BACKGROUND

[0002] To solve the problem of over-dosing when using the container to sprinkle powder, the existing quantitative container uses spring type pressing structure to press the button connected with spring to control the amount of powder to be sprinkled each time, so that the amount of powder can be quantified and uniform each time. However, once the use time of the quantitative container is prolonged, the spring elasticity is easily fatigued, which may cause the material to be stuck, and eventually lead to the whole failure. In addition, the existing quantitative container is mostly a one-piece structure, and the only place that can be disassembled is the container body for powder installation. Therefore, when the material is stuck or fails, the pressing structure cannot be disassembled to remove the obstacle, and only the whole can be written off. Furthermore, the existing quantitative container is only suitable for fine powders such as pepper and salt, and cannot be used for large particle materials such as laundry granules.

[0046] Referring to Figures 1 to 3 , an embodiment of a storage container 100 is adapted for storing a plurality of particles (not shown) and enabling a metered amount of the particles to be removed from the storage container 100. The storage container 100 comprises a storage tank 1 and a dosing device 10.

[0047] Referring to Figure 5 , the storage tank 1 is cylindrical and has a storage space 11 for storing large particles such as laundry particles and fragrance particles, but in other embodiments, the storage space 11 can also be used to store small powders. The storage tank 1 has an outer circumferential surface 12 that is diamond-patterned and roughened to provide a non-slip effect when a user holds the storage tank 1.

[0048] Referring to Figures 1 to 3 , the dosing device 10 includes a guide frame 2, an inlet cover 3, and an outlet cover 4.

[0049] Referring to Figures 2 to 4 , Figure 6 and Figure 7 , the guide frame 2 includes a first barrier 22, a second barrier 23, a connecting pipe 24, a pivot assembly 25, a positioning hook 26, an annular protrusion 27, and a support rod 28.

[0050] The first barrier 22 has an end face 221 facing the storage tank 1, a back face 222 opposite the end face 221, a first limiting end face 223, and a second limiting end face 224. The first barrier 22 has an axis hole 225 and an arc-shaped guide groove 226. The axis hole 225 extends between the end face 221 and the back face 222. The arc-shaped guide groove 226 extends between the end face 221 and the back face 222, and the first limiting end face 223 and the second limiting end face 224 are located at opposite ends of the arc-shaped guide groove 226.

[0051] The second barrier 23 is spaced apart from the first barrier 22 and has an end face 231 facing away from the first barrier 22, a back face 232 opposite the end face 231, a first limiting end face 233, and a second limiting end face 234. The second barrier 23 has an axis hole 235 and an arc-shaped guide groove 236. The axis hole 235 extends between the end face 231 and the back face 232. The arc-shaped guide groove 236 extends between the end face 231 and the back face 232, and the first limiting end face 233 and the second limiting end face 234 are located at opposite ends of the arc-shaped guide groove 236.

[0052] The connecting pipe 24 is a hollow cylinder, and is connected between the first curtain 22 and the second curtain 23, and cooperates with the first curtain 22 and the second curtain 23 to define a certain amount of material guiding hole 21. The certain amount of material guiding hole 21 is a through hole with a single hole diameter. More specifically, the certain amount of material guiding hole 21 has an inlet 211 defined by the first curtain 22, and an outlet 212 opposite to the inlet 211 and defined by the second curtain 23. That is, the through hole has the inlet 211 at one end connected to the first curtain 22, and the outlet 212 at the other end connected to the second curtain 23. The connecting pipe 24 has two stop shoulder surfaces 241, one of which is adjacent to the back surface 222 of the first curtain 22, and the other of which is adjacent to the back surface 232 of the second curtain 23. The amount of particles that the connecting pipe 24 can accommodate is the amount of particles that is limited to be moved out each time the storage container 100 is used. In other words, the amount of particles that is moved out each time depends on the radius and height of the connecting pipe 24.

[0053] The pivot assembly 25 is provided on the first curtain 22, and has a plurality of retaining hooks 251. The retaining hooks 251 are arranged in a ring shape on the outer periphery of the first curtain 22 and are spaced apart from each other. Each of the retaining hooks 251 has a first arc-shaped retaining hook portion 252. One of each two adjacent retaining hooks 251 has a second arc-shaped retaining hook portion 253. More specifically, in each of the retaining hooks 251 having the second arc-shaped retaining hook portion 253, the first arc-shaped retaining hook portion 252 is away from the first curtain 22, and the second arc-shaped retaining hook portion 253 is adjacent to the first curtain 22.

[0054] The positioning hook 26 is provided on the second curtain 23 and has elasticity, and has a slightly circular hook portion 261 adjacent to the end surface 231 of the second curtain 23.

[0055] The annular protrusion 27 protrudes from the end surface 231 of the second curtain 23 and has a circular ring shape.

[0057] The support rod 28 is connected between the first curtain 22 and the second curtain 23, and more specifically, both ends of the support rod 28 are connected to the back surface 222 of the first curtain 22 and the back surface 232 of the second curtain 23, respectively. The support rod 28 is used to support the first curtain 22 and the second curtain 23 together with the connecting pipe 24, so that the first curtain 22 can be kept balanced to avoid the first curtain 22 collapsing to the second curtain 23 due to gravity, which can damage the material guiding rack 2.

[0058] See Figure 2 and Figure 3 , Figure 8 and Figure 9 The feed cover 3 is rotatably pivotally connected to one end of the guide frame 2 near the first shield 22, and is detachably assembled to the storage tank 1 and the guide frame 2. The feed cover 3 has a guide wall 31, a peripheral wall 32, a protruding piece 33, and a shaft connection assembly 34. The feed cover 3 has a feed hole 35.

[0059] The guide wall 31 is inclined to the peripheral wall 32 and forms the feed hole 35. The guide wall 31 is inclined toward the feed hole 35 to guide the particles in the storage space 11 to move out of the feed hole 35.

[0060] The peripheral wall 32 is rotatably pivotally connected to the guide frame 2 and is used for rotational operation, and is formed around the outer periphery of the guide wall 31. The peripheral wall 32 has an outer peripheral surface 321. The peripheral wall 32 forms a first annular groove 322. The outer peripheral surface 321 is used for rotational operation, and is diamond-patterned and rough, so that when the user holds the feed cover 3, the rough outer peripheral surface 321 provides a non-slip effect. The first annular groove 322 is used for the first arc-shaped retaining hook 252 to engage, and the first annular groove 322 is rotatable relative to the first arc-shaped retaining hook 252.

[0061] The protruding piece 33 protrudes from the guide wall 31 and is arc-shaped corresponding to the arc-shaped guide groove 226 of the first shielding wall 22. The protruding piece 33 is embedded in the arc-shaped guide groove 226 and can move between the first limiting end face 223 and the second limiting end face 224 along the extension direction of the arc-shaped guide groove 226.

[0062] The shaft connection assembly 34 protrudes from the guide wall 31 toward the guide frame 2 and is shafted into the shaft hole 225 of the first shielding wall 22. The shaft connection assembly 34 has a plurality of hooks 341 and a stop block 342. The hooks 341 pass through the shaft hole 225 and are snapped onto the back surface 222. The stop block 342 passes through the shaft hole 225 to abut against the corresponding stop shoulder surface 241, and the stop block 342 is rotatable relative to the stop shoulder surface 241.

[0063] The diameter of the feed inlet 35 is equal to or greater than the diameter of the metering guide orifice 21, and it can be shielded by the first shielding wall 22. The feed inlet 35 is used to communicate with the feed inlet 211 of the metering guide orifice 21, and the feed cover 3 can be operated to rotate relative to the guide frame 2 so that the feed inlet 35 communicates with the feed inlet 211. The usage of the feed cover 3 will be further explained in subsequent paragraphs.

[0064] See Figures 10 to 13 The feed cover 3 can be located at a non-feeding position (e.g., where the feed hole 35 is covered by the first shielding wall 22) of the feed hole 35. Figure 10 and Figure 11 As shown), and the feed hole 35 is connected to a feed position of the feed inlet 211 (e.g. Figure 12 and Figure 13 The feed cover 3 rotates between the indicated positions. When the feed cover 3 is in the non-feeding position, the first limiting end face 223 of the first shield 22 is used to block the protruding piece 33, thereby limiting the feed cover 3 to the non-feeding position. When the feed cover 3 is in the feeding position, the second limiting end face 224 of the first shield 22 is used to block the protruding piece 33, thereby limiting the feed cover 3 to the feeding position.

[0065] See Figure 2 and Figure 3 , Figure 14 and Figure 15 The discharge cover 4 is rotatably pivotally connected to the other end of the guide frame 2 opposite to the inlet cover 3, and is detachably assembled to the guide frame 2 and the inlet cover 3. It has an end wall 41, a surrounding wall 42, a protruding piece 43, and a shaft connection assembly 44. The discharge cover 4 has a discharge hole 45.

[0066] The end wall 41 rotatably abuts against the annular protrusion 27 to avoid direct contact and friction between the surface of the end wall 41 and the surface of the second shielding wall 23, thereby preventing any obstruction when rotating the discharge cover 4. The end wall 41 has a first positioning groove 411 with its opening facing the guide frame 2 and slightly circular, and a second positioning groove 412 spaced apart from the first positioning groove 411. The first positioning groove 411 and the second positioning groove 412 are respectively used to allow the hook portion 261 of the positioning hook 26 to be disengaged and latched.

[0067] The surrounding wall 42 is rotatably pivotally connected to the guide frame 2 and is used for rotational operation, and is formed around the outer periphery of the end wall 41. The surrounding wall 42 has an outer surrounding surface 421 and a second annular groove 422. The outer surrounding surface 421 is used for rotational operation, has a diamond pattern, and is a rough surface, so that when the user holds the discharge cover 4, the rough outer surrounding surface 421 provides a non-slip effect. The second annular groove 422 is used for the second arc-shaped retaining hook 253 to engage, and the second annular groove 422 is rotatable relative to the second arc-shaped retaining hook 253. The surrounding wall 42 and the peripheral wall 32 are used for pivoting the pivot assembly 25 of the guide frame 2. That is, the guide frame 2 allows the peripheral wall 32 and the surrounding wall 42 to share the pivot assembly 25, thereby enabling the guide frame 2 to achieve a material-saving effect. In addition, the surrounding wall 42 is adjacent to the peripheral wall 32, and the inlet cover 3 and the outlet cover 4 together cover the guide frame 2 without exposing the guide frame 2, so that the storage tank 1, the inlet cover 3 and the outlet cover 4 form a cylinder in appearance, thereby improving the overall appearance and consistency of the storage container 100.

[0068] The protruding piece 43 protrudes from the end wall 41 and is arc-shaped corresponding to the arc-shaped guide groove 236 of the second shielding wall 23. The protruding piece 43 is embedded in the arc-shaped guide groove 236 and can move between the first limiting end face 233 and the second limiting end face 234 along the extension direction of the arc-shaped guide groove 236.

[0069] The shaft connection assembly 44 protrudes from the end wall 41 toward the guide frame 2 and is shafted to the shaft hole 235 of the second shielding wall 23. It has multiple hooks 441 and a stop block 442. The hooks 441 pass through the shaft hole 235 and are engaged with the back surface 232. The stop block 442 passes through the shaft hole 235 and abuts against the corresponding stop shoulder surface 241, and the stop block 442 is rotatable relative to the stop shoulder surface 241.

[0070] The discharge hole 45 is formed by the end wall 41. The diameter of the discharge hole 45 is equal to or greater than the diameter of the metering guide hole 21, and it can be shielded by the second shielding wall 23. The discharge hole 45 is used to communicate with the discharge port 212 of the metering guide hole 21, and the discharge cover 4 can be operated to rotate relative to the guide frame 2 so that the discharge hole 45 communicates with the discharge port 212. The usage of the discharge cover 4 will be further explained in subsequent paragraphs.

[0071] See Figures 16 to 19The discharge cover 4 can be located at a non-discharge position (e.g., where the discharge hole 45 is covered by the second shielding wall 23) of the discharge hole 45. Figure 16 and Figure 17 As shown), and the discharge hole 45 is connected to a discharge position of the discharge port 212 (e.g. Figure 18 and Figure 19 The material discharge cover 4 rotates between the two positions shown. When the discharge cover 4 is in the non-discharge position, the first limiting end face 233 of the second shield 23 is used to stop the protruding piece 43, thereby limiting the discharge cover 4 to the non-discharge position. Furthermore, the hook portion 261 of the positioning hook 26 engages with the first positioning groove 411 to reinforce the positioning of the discharge cover 4 in the non-discharge position. When the discharge cover 4 is in the discharge position, the second limiting end face 234 of the second shield 23 is used to stop the protruding piece 43, thereby limiting the discharge cover 4 to the discharge position. Furthermore, the hook portion 261 of the positioning hook 26 engages with the second positioning groove 412 to further reinforce the positioning of the discharge cover 4 in the discharge position.

[0072] See Figures 10 to 13 , Figures 16 to 19 The following describes how the storage container 100 is used.

[0073] When the particles are stored in the storage space 11 and the discharge cover 4 is in the non-discharge position, firstly, the inlet cover 3 is rotated to the inlet position so that some of the particles in the storage space 11 slide from the inlet hole 35 to the metering guide hole 21 due to gravity and the inclined surface of the guide wall 31.

[0074] Next, the feed cover 3 is rotated from the feed position to the non-feed position, and the discharge cover 4 is rotated from the non-discharge position to the discharge position. In this case, when the feed cover 3 is in the non-feed position, the feed hole 35 is blocked by the first shielding wall 22 to restrict the particles in the storage space 11 from entering the metering guide hole 21. In addition, when the discharge cover 4 is in the discharge position, the discharge hole 45 is connected to the discharge port 212 to allow the particles in the metering guide hole 21 to be removed from the storage container 100.

[0075] In this way, the capacity limitation of the metering guide hole 21 can control the amount of particles discharged each time. Furthermore, by rotating the feed cover 3 to switch between the feed position and the non-feed position, and by rotating the discharge cover 4 to switch between the discharge position and the non-discharge position, the timing of particle feeding and discharging can be effectively controlled. Moreover, in the event of a jam, the guide frame 2, the feed cover 3, and the discharge cover 4 can be disassembled individually, thus overcoming the limitation of existing one-piece metering containers that are rendered unusable upon failure.

[0076] In summary, by rotating the inlet cover 3 and the outlet cover 4, the storage container 100 allows the contents of the storage tank 1 to quantitatively enter the quantitative guide hole 21 through the inlet hole 35 when the inlet 211 of the guide frame 2 is connected to the inlet hole 35. Furthermore, when the inlet hole 35 is closed and the outlet 212 is connected to the outlet hole 45, the contents of the quantitative guide hole 21 can be discharged through the outlet hole 45. In this way, the storage container 100 can be quantitatively discharged each time it is used. Moreover, the detachable guide frame 2, inlet cover 3, and outlet cover 4 allow the storage container 100 to be disassembled to remove obstacles when it jams. Therefore, the purpose of this invention is indeed achieved.

[0077] The above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
