DETAILED DESCRIPTION
[0032] The embodiments of the present application are described below with reference to the accompanying drawings.
[0033] Please refer to Figure 1 As shown, the dispenser of the present application can be used in household appliances such as dishwashers. It can be used to regularly dispense dishwashing powder or rinse aid for cleaning items.
[0034] Please refer to Figure 2 and Figure 5As shown, the dispenser of the present application includes a body 1, a cover 2, a rotating arm 31 and a first switch assembly 32. The body 1 includes a first connecting portion 11, a mounting portion and at least one accommodating cavity portion, the mounting portion includes a through hole 12 for mounting the first switch assembly 32, and the accommodating cavity portion has an accommodating cavity 13 that can be used to accommodate detergent. The first connecting portion 11 is located at the outer bottom of the body 1, the through hole 12 penetrates the body 1 in the vertical direction, the opening of the accommodating cavity 13 faces upward, and the accommodating cavity 13 can be suitable for accommodating dishwashing powder, etc. Please refer to Figure 3 and Figure 4 As shown, the cover 2 includes a first component 21. The cover 2 is mounted on the body 1 and can be used to close and open the opening of the accommodating chamber 13. When the cover 2 opens the accommodating chamber 13, dishwashing powder can be added to the washing chamber or replenished into the accommodating chamber 13. When the cover 2 closes the accommodating chamber 13, it can reduce the leakage of dishwashing powder in the accommodating chamber 13.
[0035] Please refer to Figure 6 As shown, the rotating arm 31 includes a second connecting portion 311, which is located at one end of the rotating arm 31. The rotating arm 31 is mounted on the body 1. The first connecting portion 11 and the second connecting portion 311 are adapted to each other, so that the rotating arm 31 and the body 1 are rotationally connected, and the rotating arm 31 can rotate around the first connecting portion 11. The rotating arm 31 is connected to the first switch assembly 32, and the rotating arm 31 can drive the first switch assembly 32 to rotate.
[0036] Please refer to Figure 5 and Figure 8 As shown, the first connecting portion 11 includes a sixth column 111, and the second connecting portion 311 includes a sixth hole 3111. The sixth hole 3111 is a through hole and is located at one end of the rotating arm 31. The sixth column 111 is at least partially located in the sixth hole 3111. The sixth column 111 and the sixth hole 3111 are clearance-fitted, allowing the sixth column 111 and the sixth hole 3111 to rotate relative to each other, and the rotating arm 31 can rotate around the sixth column 111.
[0037] Please refer to Figure 11 As shown, the first switch assembly 32 includes a first connecting member 321, a second connecting member 322, and a third connecting member 323. One end of the first connecting member 321 and the second connecting member 322 are fixedly connected, reducing the possibility of relative rotation between the first connecting member 321 and the second connecting member 322. When the first connecting member 321 rotates, the second connecting member 322 rotates with the rotation of the first connecting member 321. The other end of the second connecting member 322 is fixedly connected to the third connecting member 323, reducing the possibility of relative rotation between the second connecting member 322 and the third connecting member 323. When the second connecting member 322 rotates, the third connecting member 323 rotates with the rotation of the second connecting member 322.
[0038] The first connecting member 321 and the second connecting member 322 can be fixed by means of one-piece molding or clamping, and the second connecting member 322 and the third connecting member 323 can be fixed by means of one-piece molding or clamping. In order to achieve the purpose of assembly, there is at least one clamping fixation between the first connecting member 321 and the second connecting member 322 and the third connecting member 323. Figure 9 and Figure 10 As shown, the first column portion 3211 includes a fourth hole 3214 and a first engaging groove 3215. The first engaging groove 3215 is recessed into the inner wall corresponding to the fourth hole 3214. The second connecting member 322 includes a fourth column portion 3221 and a second engaging portion 3222. The second engaging portion 3222 protrudes from the sidewall of the fourth column portion 3221. The fourth column portion 3221 is at least partially located within the fourth hole 3214, and the second engaging portion 3222 is at least partially confined within the first engaging groove 3215. The first engaging groove 3215 and the second engaging portion 3222 cooperate with each other to reduce the possibility of relative rotation between the fourth column portion 3221 and the fourth hole 3214.
[0039] The first connecting member 321 further includes a fourth clamping portion 3219, which is located at the top end of the first connecting member 321. The second connecting member 322 includes a third clamping portion 3223, which is located at an end of the second connecting member 322 away from the third connecting member 323. The third clamping portion 3223 and the fourth clamping portion 3219 cooperate with each other to reduce the possibility of axial movement of the first connecting member 321 and the second connecting member 322 along the second connecting member 322. Under the combined action of the first clamping groove 3215, the second clamping portion 3222, the third clamping portion 3223, and the fourth clamping portion 3219, the possibility of relative displacement and rotation between the first connecting member 321 and the second connecting member 322 is reduced, thereby ensuring relative fixation between the first connecting member 321 and the second connecting member 322.
[0040] Please refer to Figure 3 and Figure 11 As shown, the third connecting member 323 includes a second part 3231, and the third connecting member 323 extends radially outward from the end of the second connecting member 322 away from the first connecting member 321. The second part 3231 is located at the end of the third connecting member 323 away from the second connecting member 322. The second part 3231 is adapted to the first part 21, and the first part 21 and the second part 3231 cooperate to have a locked state and a disengaged state. When the first part 21 and the second part 3231 are in the locked state, the cover body 2 closes the accommodating cavity 13.
[0041] Please refer to Figure 3 and Figure 6As shown, the first connecting member 321 is connected to the rotating arm 31, and the lower ends of the first connecting member 321 and the second connecting member 322 are fixed in position. The second connecting member 322 at least partially passes through the through hole 12. The third connecting member 323 is located below the cover 2 and above the second connecting member 322. The rotating arm 31 can drive the first connecting member 321 to rotate, the first connecting member 321 drives the second connecting member 322 to rotate, and the second connecting member 322 drives the third connecting member 323 to rotate. Therefore, the rotating arm 31 can drive the third connecting member 323 to rotate.
[0042] Please refer to Figure 9 and Figure 11 As shown, the first connecting member 321 and the second connecting member 322 are detachably fixed. The first connecting member 321 includes a first column 3211, a third connecting member 3212, and a second column 3213. The first column 3211, the third connecting member 3212, and the second column 3213 can be integrally formed by injection molding. The third connection portion 3212 extends radially outward from the side wall of the first column portion 3211 away from one end of the third connection member 323. The third connection portion 3212 connects the first column portion 3211 and the second column portion 3213. The angle between the axis of the first column portion 3211 and the axis of the second column portion 3213 of the third connection portion is less than 15°, such as 0° or 5°. When the angle between the axis of the first column portion 3211 and the axis of the second column portion 3213 is 0°, the axis of the first column portion 3211 and the axis of the second column portion 3213 are roughly parallel, which can facilitate the installation of the first switch assembly 32 and the rotating arm 31 and reduce the error generated during rotation.
[0043] Please refer to Figure 11 As shown, the length of the third connecting member 323 is H1, that is, on a plane perpendicular to the axial direction of the second connecting member 322, the length of the second component 3231 from the second connecting member 322 is H1, and the length of the third connecting portion 3212 is H2, that is, on a plane perpendicular to the axial direction of the second connecting member 322, the length of the second column 3213 from the second connecting member 322 is H2, and the length H2 of the third connecting portion 3212 is less than the length H1 of the third connecting member 323, that is, the distance between the second component 3231 and the second connecting member 322 is greater than the distance between the second column 3213 and the second connecting member 322. When the first switch assembly 32 rotates, the displacement distance of the second component 3231 on the third connecting member 323 is greater, that is, the relative displacement between the first component 21 and the second component 3231 is greater, which improves the stability of the first component 21 and the second component 3231 from the locked state to the disengaged state, and improves the reliability of the cover body 2 opening the accommodating cavity 13. Please refer to the third connecting portion, the third connecting portion, the third connecting portion, and the third connecting portion for details. Figure 8As shown, the rotating arm 31 includes a first section 318, a first switch connecting portion 310 connected to the first section 318, and a second section 319 connected to the first switch connecting portion 310. The first switch connecting portion 310 is located between the first section 318 and the second section 319, and the sixth hole 3111 is located at the end of the first section 318 away from the first switch connecting portion 310. The angle between the first section 318 and the second section 319 is between 135° and 180°. This arrangement not only allows the rotating arm 31 to be properly positioned on the outer bottom of the body 1, but also appropriately extends the overall length of the rotating arm 31, so that at the same rotation angle, the end of the rotating arm 31 away from the sixth hole 3111 moves a longer distance.
[0044] Please refer to Figure 8 、 Figure 12 and Figure 13 As shown, the first switch connecting portion 310 has a first hole 312 in the rotating arm. The first hole 312 is a through hole, and the maximum width of the first hole 312 is greater than the maximum width of the first connecting member 321, so that the first connecting member 321 can be at least partially accommodated in the first hole 312. The first switch connecting portion 310 includes an extension 313, which extends radially inward from the inner wall of the first hole 312. The extension 313 includes a second hole 314. The angle between the axis of the second hole 314 and the axis of the first hole 312 is less than 15°, such as 0° or 5°. When the angle between the axis of the second hole 314 and the axis of the first hole 312 is 0°, the axis of the second hole 314 is substantially parallel to the axis of the first hole 312, thereby improving the stability of the connection between the rotating arm 31 and the first connecting member 321. The inner diameter of the second hole 314 is larger than the outer diameter of the second column portion 3213, so that the second column portion 3213 is at least partially located in the second hole 314, and the clearance between the second column portion 3213 and the second hole 314 is matched, so that the second column portion 3213 can rotate in the second hole 314, reducing the possibility of jamming between the second column portion 3213 and the second hole 314, and improving the smoothness of the movement of the first connecting member 321 driven by the rotating arm 31.
[0045] Please refer to Figure 5 and Figure 6As shown, the dispenser also includes a second switch assembly 33, an elastic device 4, and a solenoid valve 5. A second switch connection portion 3193 is provided at one end of the second segment 319, distal from the first switch connection portion 310. The second switch connection portion 3193 is connected to the second switch assembly 33. The elastic device 4 may be a spring, etc. The body 1 includes a first support portion 14 and a fourth groove 15. The rotating arm 31 includes a second support portion 317, which is located between the connection between the second segment 319 and the solenoid valve 5 and the connection between the second segment 319 and the second switch assembly 33. The first support portion 14 and the second support portion 317 are disposed opposite each other. One end of the elastic device 4 abuts the bottom wall of the first support portion 14, and the other end abuts the bottom wall of the second support portion 317. The rotating arm 31 is at least partially located within the fourth groove 15, and the elastic device 4 is at least partially located within the fourth groove 15. A bent connection portion 3192 is provided between the connection between the second support portion 317, the second section 319, and the second switch assembly 33, so that the connection between the second support portion 317, the second section 319, and the second switch assembly 33 has a height difference in the elastic deformation direction of the elastic device 4. That is, the connection between the second section 319 and the solenoid valve 5, the second support portion 317, the bent connection portion 3192, and the connection between the second section 319 and the second switch assembly 33 are provided in this order. The provision of the bent connection portion 3192 can increase the relative distance between the first support portion 14 and the second support portion 317, increase the compressible displacement of the spring, and increase the diversity of elastic options.
[0046] Please refer to Figure 7 and Figure 8 As shown, the second section 319 also includes a seventh column portion 3191, which is located in the middle of the second section 319. The distance between the seventh column portion 3191 and the first switch connecting portion 310 accounts for 1 / 3 to 2 / 3 of the total length of the second section 319. The seventh column portion 3191 is connected to the solenoid valve 5, so that the solenoid valve 5 drives the rotating arm 31 to move, that is, the second supporting portion 317 is located between the seventh column portion 3191 and the second switch connecting portion 3193, and the bent connecting portion 3192 is located between the second supporting portion 317 and the second switch connecting portion 3193. When the stroke of the solenoid valve 5 is constant, the displacement of the first switch connecting part 310 at the connection between the first switch connecting part 310 and the second section 319 is the largest, and the extension part 313 is provided at the connection between the first switch connecting part 310 and the second section 319. The extension part 313 extends radially inward from the inner wall of the first hole 312 of the first switch connecting part 310, that is, the second hole 314 is also provided at the connection between the first switch connecting part 310 and the second section 319.
[0047] Please refer to Figure 12 and Figure 13As shown, the second column 3213 is connected to the second hole 314, so that the rotating arm 31 drives the first connecting member 321 to rotate. When the stroke of the solenoid valve 5 is constant, the displacement of the second hole 314 on the extension portion 313 is the largest, so the rotation angle of the first connecting member 321 is the largest, so that the stroke of the second component 3231 on the third connecting member 323 is the largest, thereby improving the reliability of opening the cover body 2.
[0048] Please refer to Figure 2 and Figure 12 As shown, once the position of the first component 21 is determined, the first component 21 and the second component 3231 engage in a snap-fit arrangement. Therefore, the position of the second component 3231 is determined by the determination of the first component 21, and the position of the third connecting portion 3212 is determined by the determination of the position of the second column 3213. The position of the first component 21 can be adjusted according to production needs. The angle between the third connecting portion 3212 and the third connecting member 323 is between 135° and 160°. For example, when the first component 21 is located in the middle of the lid body 2, the angle between the third connecting portion 3212 and the third connecting member 323 is 145°. The diverse position of the first component 21 allows the angle between the third connecting portion 3212 and the third connecting member 323 to be adjusted according to the first component 21, thereby improving the reliability of lid opening.
[0049] Please refer to Figure 6 and Figure 7 As shown, please refer to Figure 6 and Figure 7As shown, the rotating arm 31 can move between the first position L1 and the second position L2. When the rotating arm 31 is in the first position L1, the first component 21 and the second component 3231 are locked, and the cover body 2 closes the accommodating cavity 13; when the rotating arm 31 moves from the first position L1 to the second position L2, the first component 21 and the second component 3231 are disengaged, and the cover body 2 opens the accommodating cavity 13, that is, when the rotating arm 31 rotates from the first position L1 to the second position L2, the extension portion 313 drives the second column portion 3213 on the first connecting member 321 to move, so that the rotating arm 31 drives the first connecting member 321 to rotate, and the first connecting member 321 drives the third connecting member 323, and the second component 3231 on the third connecting member 323 is relatively displaced from the first component 21, so that the first component 21 and the second component 3231 are changed from a locked state to a disengaged state. When the stroke of the solenoid valve 5 is constant, the rotation angle of the third connecting part 3212 on the first connecting part 321 is greater than the rotation angle of the rotating arm 31 when it moves from the first position L1 to the second position L2, so that the rotation angle of the first connecting part 321 is greater than the rotation angle of the rotating arm 31, which increases the rotation angle of the third connecting part 323, and then increases the relative displacement between the first component 21 and the second component 3231, thereby improving the reliability of opening the cover body 2 and reducing the occurrence of poor opening of the cover; when the rotation angle of the rotating arm 31 is constant, the displacement of the end of the rotating arm 31 away from the second connecting part 311 becomes larger, thereby improving the stability of opening the cleaner.
[0050] In other embodiments, see Figure 14As shown, the first connecting member 321 includes a third column portion 3218, and the third connecting portion 3212 connects the first column portion 3211 and the third column portion 3218. The included angle between the axis of the first column portion 3211 and the axis of the third column portion 3218 is less than 15°, such as 0° or 5°. When the included angle between the axis of the first column portion 3211 and the axis of the third column portion 3218 is 0°, the axis of the first column portion 3211 and the axis of the third column portion 3218 are substantially parallel to the rotating arm. When the first connecting member 321 is assembled, one end of the third column portion 3218 is connected to the third connecting portion 3212, and the other end of the third column portion 3218 is away from the third connecting member 323. The first column portion 3211, the third connecting portion 3212, and the third column portion 3218 can be integrally formed by injection molding. The pivot arm 31 includes a third hole 315. The included angle between the axis of the third hole 315 and the axis of the first hole 312 is less than 15°, such as 0° or 5°. When the included angle between the axis of the third hole 315 and the axis of the first hole 312 is 0°, the axis of the third hole 315 is substantially parallel to the axis of the first hole 312. When the first column 3211 is engaged with the first hole 312 and the third column 3218 is engaged with the third column 315, this facilitates the installation of the first switch assembly 32 and the pivot arm 31 and reduces errors during rotation. The inner diameter of the third hole 315 is larger than the outer diameter of the third column 3218, resulting in a clearance fit between the third column 3218 and the third hole 315. The rotational connection between the third column 3218 and the third hole 315 reduces the possibility of the third column 3218 and the third hole 315 becoming stuck, thereby improving the smoothness of the movement of the pivot arm 31 driving the first connecting member 321. The third hole 315 may be a through hole or may be replaced by a groove.
[0051] In other embodiments, see Figure 15 As shown, the rotating arm 31 includes a fifth hole 316 and a first groove 3161. The first groove 3161 is formed on the inner wall of the fifth hole 316. The first connecting member 321 includes a fifth column 3216 and a fourth connecting portion 3217. The fourth connecting portion 3217 extends radially outward from the sidewall of the fifth column 3216. The diameter of the fifth column 3216 is smaller than that of the fifth hole 316, allowing the fifth column 3216 to be accommodated in the fifth hole 316. The fourth connecting portion 3217 mates with the first groove 3161. The fourth connecting portion 3217 is at least partially located in the first groove 3161, allowing the first groove 3161 to guide the rotation of the fourth connecting portion 3217. During rotation, the rotating arm 31 utilizes the first groove 3161 to drive the fourth connecting portion 3217 to rotate, thereby driving the first connecting member 321 to rotate. This simple structure is easy to install and manufacture.
[0052] Please refer to Figure 10 and Figure 11As shown, the second connecting member 322 is connected to one end of the third connecting member 323 at the end away from the first connecting member 321. The second connecting member 322 and the third connecting member 323 are integrally formed through an injection molding process. The angle between the second connecting member 322 and the third connecting member 323 is between 80° and 100°, such as 90°. That is, the second connecting member 322 and the third connecting member 323 are arranged vertically, so that when the second connecting member 322 is installed vertically, the third connecting member 323 is in a horizontal state, thereby optimizing the space of the distributor. The second component 3231 is located at the end of the third connecting member 323 away from the second connecting member 322. The second connecting member 322 and the second component 3231 are respectively located at opposite ends of the third connecting member. When the stroke of the solenoid valve 5 is constant, the angle of rotation of the second connecting portion 311 is constant. At this time, the stroke of the second component 3231 is large, the cover opening margin is large, and the reliability of the opening of the cover body 2 is improved.
[0053] Please refer to Figure 6 and Figure 7 As shown, when the solenoid valve 5 is de-energized, the rotating arm 31 is in the first position L1, one end of the elastic device 4 abuts against the bottom wall of the first support portion 14, and the other end of the elastic device 4 abuts against the bottom wall of the second support portion 317. At this time, the elastic device 4 is subjected to less force; when the solenoid valve 5 is energized, the valve core of the solenoid valve 5 drives the rotating arm 31 to move from the first position L1 to the second position L2. At this time, the elastic device 4 is subjected to greater force; when the solenoid valve 5 is closed, under the action of the elastic device 4, the rotating arm 31 moves from the second position L2 to the first position L1.
[0054] Please continue to participate Figure 6 and Figure 7 As shown, the second switch assembly 33 also includes a first limiting portion 331 and a second limiting portion 332. The first limiting portion 331 and the second limiting portion 332 are spaced apart. When the solenoid valve 5 is in the power-off state, under the action of the spring force, the second switch connecting portion 3193 abuts against the first limiting portion 331, and the second switch connecting portion 3193 maintains a certain distance from the second limiting portion 332. The rotating arm 31 is in the first position L1. At this time, the second switch assembly 33 restricts the outflow of the cleaning agent. When the solenoid valve 5 is switched from the power-off state to the power-on state, the second switch connecting portion 3193 gradually abuts against the first limiting portion 331. The second limiting portion 332 approaches until it abuts against the second limiting portion 332, and then the second switch connecting portion 3193 drives the second switch component 33 to operate, so that the second switch component 33 opens the detergent delivery chamber to deliver the detergent; when the solenoid valve 5 switches from the energized state to the de-energized state, under the action of the spring force, the second switch connecting portion 3193 gradually approaches the first limiting portion 331 until it abuts against the first limiting portion 331, and then the second switch connecting portion 3193 drives the second switch component 33 to operate, so that the second switch component 33 closes the detergent delivery chamber.
