[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Other technical solutions obtained by technical personnel in the field without making creative work belong to the protection scope of the utility model. In addition, it should be understood that the following "upper", "lower", "left", "right", "longitudinal", "lateral", "inside", "outside", "vertical", "horizontal", "top", "bottom" and other words indicating orientation or position relationship are only based on the orientation or position relationship shown in the drawings, only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the utility model.

[0029] like Figure 1-Figure 14 As shown, a dispenser of an embodiment includes a main body 1 and a first cover body 2, the main body 1 has a first cavity 100 that is recessed downward, the first cover body 2 is mounted on the main body 1 and at least a portion of the first cover body 2 is located above the first cavity 100 in the vertical direction, and the first cover body 2 can be displaced relative to the main body 1 to open or close the first cavity 100; the dispenser includes a button 3 and an abutment shaft 4, the button 3 is rotatably mounted on the first cover body 2, the abutment shaft 4 is mounted on the main body 1, the button 3 has a first position and a second position, when the button 3 is located at the first position, the button 3 contacts the abutment shaft 4, and the first cover body 2 closes the first cavity 100; when the button 3 is located at the second position, the button 3 is disengaged from the abutment shaft 4, and the first cover body 2 can open the first cavity 100.

[0030] The first cover body 2 has a through mounting hole 200, and the button 3 includes a pressing portion 301 and a rotating portion 302. At least a part of the pressing portion 301 is located in the mounting hole 200, and the rotating portion 302 is located on the side of the first cover body 2 facing the main body 1. A limiting column 202 is provided on the side wall of the first cover body 2 facing the main body 1. The limiting column 202 is located on one side of the rotating portion 302. The rotating portion 302 has a first limiting portion 310 facing the limiting column 202. The first limiting portion 310 contacts the limiting column 202 and is limited in the horizontal direction by the limiting column 202, or there may be a certain gap between the first limiting portion 310 and the limiting column 202. Under the limitation of the limiting column 202, the rotating portion 302 can only be slightly displaced in the horizontal direction, and the slight displacement does not affect the cooperation between the button and the abutment shaft 4.

[0031] The rotating portion 302 has a first inclined portion 304 , which extends from the side of the rotating portion 302 facing the first cover 2 toward the limiting column 202 . In the vertical direction, the first inclined portion 304 is located above at least part of the first limiting portion 310 .

[0032] The first cavity 100 is used for placing detergent. When the button 3 is in the first position, the first cover body 2 closes the first cavity 100, and the rotating portion 302 of the button 3 contacts the abutting portion to limit the displacement of the first cover body 2. At this time, the detergent is located in the first cavity 100 and does not flow out. When the button 3 is slid to the second position, the rotating portion 302 of the button 3 is disengaged from the abutting portion. At this time, the first cover body 2 can be displaced, so that the first cover body 2 can open the first cavity 100, and the detergent in the first cavity 100 can flow out, thereby washing the laundry.

[0033] Since the rotating part 302 has a certain length, a limiting column 202 is used to limit the rotating part 302 to prevent the rotating part 302 from shifting in its length direction, thereby ensuring the accurate fit between the rotating part 302 and the abutment shaft 4, and further ensuring that the moving button 3 can enable the rotating part 302 to be limitedly fit or disengaged from the abutment shaft 4, thereby ensuring that the first cover body 2 is accurately controlled by the button 3 to close or open the first cavity 100.

[0034] like Fig.11As shown, during the installation process of the button 3 and the first cover body 2, the rotating portion 302 is first passed through the installation hole 200 and extended to the bottom of the first cover body 2. At this time, the position height of the part of the rotating portion 302 away from the pressing portion 301 is generally lower than the lowest position height of the limiting column 202. Then, during the process of installing the pressing portion 301 into the installation hole 200, the part of the rotating portion 302 away from the pressing portion 301 will be lifted upward. During this process, the rotating portion 302 is prone to get stuck with the upper end surface of the limiting column 202; the setting of the first inclined portion 304 solves this problem well. The first inclined portion 304 allows a certain amount of clearance for the rotating portion 302 and can guide the rotating portion 302 to be installed in a suitable position along the limiting column 202. The setting of the first inclined portion 304 is highly practical, which greatly improves the installation efficiency of the button 3 and the first cover body 2, and has great benefits in the process of mass manufacturing of dispensers.

[0035] In one embodiment, in the vertical direction, the lowest height of the first inclined surface 304 is higher than the lowest height of the limiting column 202, and the rotating part 302 has a first limiting portion 310 facing the limiting column 202, and in the vertical direction, the first inclined surface 304 is located at least partially above the first limiting portion 310. The first limiting portion 310 enables the first limiting portion 310 to be matched with the limiting column 202, and when the rotating part 302 is about to deviate or deviates to a certain extent, the first limiting portion 310 and the limiting column 202 are matched to limit the deviation of the rotating part 302, so as to avoid the first inclined surface 304 contacting the limiting column 202, causing the rotating part 302 to be subjected to uneven force and causing the rotating part 302 to deviate, thereby failing to achieve a good limiting effect.

[0036] like Fig.15 As shown, in another embodiment, the limiting column 202 has a second inclined surface 2021, and the second inclined surface 2021 extends from the side of the limiting column 202 facing the body 1 to the direction close to the rotating part 302. The second inclined surface 2021 is located at the end of the limiting column 202. The function and principle of the second inclined surface 2021 are similar to the first inclined surface 304, so that the limiting column 202 has a certain clearance space relative to the rotating part 302, and can guide the rotating part 302 to be installed in a suitable position along the limiting column 202. The second inclined surface 2021 and the first inclined surface can be selected or both. As a preferred embodiment, only the first inclined surface 304 exists, and the side of the limiting column 202 facing the rotating part 202 is a plane, and the first limiting part 310 is limited corresponding to the plane, and the displacement of the rotating part 302 in a certain vertical direction can still be limited by the limiting column 202, so as to avoid the second inclined surface 2021 limiting the position of the rotating part 302 within the position range.

[0037] In one embodiment, along the length direction of the first cover body 2, the length of the first inclined portion 304 is defined as L1, and the length of the limiting column 202 is defined as L2, L1 ≥ 1.2 × L2; the length of the first inclined portion 304 is at least 1.2 times the length of the limiting column 202, so that when the rotating portion 302 passes through the mounting hole 200 and extends under the first cover body 2, the rotating portion 302 has sufficient position offset margin to allow the rotating portion 302 to be installed on the side of the limiting column 202 by giving way to the first inclined portion 304.

[0038] like Figure 7 As shown, in one embodiment, the first cover body 2 has a mounting ear 201 on the side facing the main body 1, and the mounting ear 201 is provided with a mounting groove 2011, and the mounting groove 2011 includes a mounting channel 20112 and a card slot 20111 connected to the mounting channel 20112, and the rotating part 302 has a rotating shaft 306 corresponding to the card slot 20111, at least part of the pressing part 301 and at least part of the rotating part 302 are respectively located on both sides of the rotating shaft 306, and the mounting channel 20112 is trumpet-shaped, and the channel of the small diameter end of the mounting channel 20112 is connected to the card slot 20111, and the inner diameter of the small diameter end of the mounting channel 20112 is smaller than the inner diameter of the card slot 20111.

[0039] Specifically, the mounting ears 201 are a pair, respectively located on both sides of the mounting hole 200, and the rotating shaft 306 of the rotating part 302 is installed in the mounting grooves 2011 of the two mounting ears 201 and rotated to match, thereby realizing the rotational match between the button 3 and the first cover 2. When the first cover 2 needs to be moved, the pressing part 301 of the button 3 is pressed, and the button 3 rotates along the rotating shaft 306, so that the rotating part 302 rotates and moves, so that the rotating part 302 is separated from the limiting column 202, that is, the two are released from the limit, so that the first cover 2 can be displaced, and the first cavity 100 is opened.

[0040] The trumpet-shaped installation channel 20112 plays a guiding role. When the rotating shaft 306 is installed into the installation groove 2011, it is first installed relatively easily into the large diameter end of the trumpet-shaped installation channel 20112, and then, with the guiding effect of its inner wall, it passes through the small diameter end of the installation channel 20112 and is clamped into the slot 20111 and received by the small diameter end limit of the installation channel 20112.

[0041] like Fig.14 As shown, in another implementation, the inner wall portion of the rotating portion 302 facing the mounting hole 200 has a first groove 309 , and the inner wall portion corresponding to the mounting hole 200 is provided with a first shaft 204 matching the first groove 309 .

[0042] like Figure 8-Figure 10As shown, in one embodiment, a first snap-fit ​​portion 307 is provided on the side of the pressing portion 301 facing the main body 1, and a corresponding first snap-fit ​​portion 203 is provided on the side of the first cover body 2 facing the main body 1. The first snap-fit ​​portion 307 includes a main body portion 3071 extending from the pressing portion 301 toward the main body 1, and a convex portion 3072 protruding from the main body portion 3071. At least part of the first snap-fit ​​portion 203 is located between the convex portion 3072 and the first cover body 2, and the width of the main body portion 3071 from the end connected to the pressing portion 301 is greater than the width of the end away from the pressing portion 301.

[0043] The cooperation between the first buckle part 307 and the first clamping part 203 enables the button 3 to be firmly installed in the installation hole 200 of the first cover body 2, reducing the probability of the button 3 being disengaged. It can be understood that when the rotating shaft 306 of the rotating part 302 is installed in the clamping slot 20111, in order to facilitate installation, the amount of the rotating shaft 306 extending into the clamping slot 20111 should not be too large, but this amount of extension affects the installation stability of the button 3 and the first cover body 2. Therefore, the cooperation structure of the first buckle part 307 and the first clamping part 203 is provided to take into account the convenience and stability of the installation of the button 3. Specifically, at least part of the first clamping part 203 is located between the protrusion 3072 and the first cover body 2, so that the second buckle part 205 can limit the vertical upward displacement of the second clamping part 308, which is consistent with the displacement direction of the rotating shaft 306 disengaging from the clamping slot 20111, thereby preventing the rotating shaft 306 from disengaging from the clamping slot 20111. On the other hand, the cooperation between the first buckle portion 307 and the first clamping portion 203 can also prevent the pressing portion 301 from excessively protruding from the first cover body 2 and affecting its normal use.

[0044] The width of the main body 3071 from the end connected to the pressing portion 301 is greater than the width of the end away from the pressing portion 301, thereby increasing the connection area between the main body 3071 and the pressing portion 301 and thus increasing the connection stability between the main body 3071 and the pressing portion 301.

[0045] like Fig.14 As shown, in another embodiment, a second snap-fitting portion 308 is provided on the side of the pressing portion 301 facing away from the main body 1, and a corresponding second snap-fitting portion 205 is provided on the side of the first cover body 2 facing away from the main body 1. The second snap-fitting portion 205 can limit the vertical upward displacement of the second snap-fitting portion 308. The structure of the second snap-fitting portion 308 and the second snap-fitting portion 205 can refer to the first snap-fitting portion 203 and the first snap-fitting portion 307, and will not be repeated here.

[0046] like Figure 4 , Figure 5As shown, in one embodiment, the abutment shaft 4 is rotatably mounted on the main body 1, the abutment shaft 4 has a first abutment portion 401, the rotating portion 302 has a second abutment portion 303, the first abutment portion 401 can contact with the second abutment portion 303, the abutment shaft 4 has a first rotation position and a second rotation position, when the abutment shaft 4 is located at the first rotation position, the first abutment portion 401 can contact with the second abutment portion 303, when the abutment shaft 4 is located at the second rotation position, the first abutment portion 401 is disengaged from the second abutment portion 303.

[0047] like Fig.12 As shown, by rotating the abutment shaft 4, the first abutment portion 401 is disengaged from the second abutment portion 303, thereby releasing the limit of the abutment shaft 4 on the rotating portion 302, and then the first cover body 2 can be displaced to open the first cavity 100. Furthermore, the rotation connection structure between the abutment shaft 4 and the main body 1 can be realized by an electromagnetic valve, and a protrusion fixed or limited to the abutment shaft is rotatably provided in the main body 1, and the protrusion can follow the displacement of the magnetic suction member of the electromagnetic valve. When the electromagnetic valve is powered on and the magnetic suction member is adsorbed and displaced, the protrusion is driven to displace, so that the protrusion rotates together with the shaft relative to the main body 1. The technology of driving the abutment shaft 4 to rotate by the electromagnetic valve is relatively common in the art and will not be described in detail. Of course, in other embodiments, the abutment shaft 4 can also be driven to rotate by a motor.

[0048] Therefore, in one embodiment, there are two ways to release the limitation of the first cover body 2 and the main body 1. The user can choose to press the button 3 or rotate the abutment shaft 4 to release the limitation of the first cover body 2 according to the specific situation, thereby opening the first cavity 100 by moving the first cover body 2 to allow the detergent in the first cavity 100 to flow out.

[0049] like Figure 8 As shown, in one embodiment, the rotating portion 302 includes a connecting portion 3021 connected to the pressing portion 301, a distal portion 3023 away from the pressing portion 301, and a middle portion 3022 located between the connecting portion 3021 and the distal portion 3023, and the second abutting portion 303 is located in the middle portion 3022.

[0050] The second abutting portion 303 is located in the middle portion 3022. On the one hand, there is a certain distance between the second abutting portion 303 and the distal end portion 3023 of the pressing portion 301, which reduces the deformation of the rotating portion 302 caused by the force of the first abutting portion 401. On the other hand, there is a certain distance between the second abutting portion 303 and the connecting portion 3021, which ensures the displacement of the second abutting portion 303 when the rotating portion 302 rotates, thereby ensuring that the second abutting portion 303 can be separated from the limit of the first abutting portion 401. That is, the second abutting portion 303 is located in the middle portion 3022, which takes into account both the structural stability of the rotating portion 302 and the release of the limit between the button 3 and the first cover 2.

[0051] In one embodiment, a clearance gap 3045 is provided on one side of the rotating portion 302 facing the main body 1, and at least a portion of the clearance gap 3045 is located on the side of the second abutting portion 303 facing the distal end portion 3023, and the lowest height of the clearance gap 3045 in the vertical direction is higher than the highest height of the first abutting portion 401.

[0052] When the abutment shaft 4 rotates to release the limit between the first abutment portion 401 and the second abutment portion 303, since the second abutment portion 303 is located in the middle portion 3022, the distal end portion 3023 of the rotating portion 302 may still limit the displacement of the first abutment portion 401. The setting of the clearance notch 3045 allows the first abutment portion 401 to release the limit of the distal end portion 3023 on the second abutment portion 303 after rotating with the abutment shaft 4, thereby ensuring that the limit between the button 3 and the first cover body 2 is released.

[0053] In one embodiment, the abutment shaft 4 includes a shaft body 402, a first abutment portion 401 connected to or integrated with the shaft body 402, the first abutment portion 401 includes an extension shaft 4011 and an abutment head portion 4012, the extension shaft 4012 extends obliquely from the shaft body 402 toward the second abutment portion 303, and the abutment head portion 4012 is located at the end of the extension shaft 4011.

[0054] like Figure 4 As shown, in one embodiment, the dispenser includes a first spring 5, one end of the first spring 5 abuts against one end of the rotating part 302 away from the pressing part 301, and the other end of the first spring 5 abuts against the first cover body 2, and the first spring 5 drives the rotating part 302 to rotate away from the first cover body 2. The pressing part 301 is pressed, and the rotating part 302 moves toward the first cover body 2, compressing the first spring 5, canceling the pressing external force of the pressing part 301, and under the action of the first spring 5, the rotating part 302 and the pressing part 301 are reset. Specifically, a first protrusion or a first groove is provided on the side of the rotating part 302 facing the first cover body 2, and one end of the first spring 5 is sleeved on the first protrusion or located in the first groove; a second protrusion or a second groove is provided at a corresponding position of the first cover body, and the other end of the first spring is sleeved on the second protrusion or located in the second groove.

[0055] like Fig.13As shown, in one embodiment, the dispenser includes a second spring 6, one end of the second spring 6 is connected to the first cover body, and the other end of the second spring 6 is connected to the body 1. Specifically, the second spring 6 can be a torsion spring, and the second spring 6 drives the first cover body to open the first cavity 100. When the button 3 is in the first position, the first cover body 2 closes the first cavity 100, and the second spring 6 is in a deformed state; when the button 3 is in the second position, that is, after the limit between the button 3 and the first cover body 2 is released, the first cover body 2 automatically displaces under the elastic deformation recovery force of the first spring 5 to open the first cavity 100. Similarly, in another embodiment, when the abutting shaft 4 is in the first rotation position, the first cover body 2 closes the first cavity 100, and the second spring 6 is in a deformed state; when the abutting shaft 4 is in the second rotation position, the first cover body 2 automatically displaces under the elastic deformation recovery force of the first spring 5 to open the first cavity 100.

[0056] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technical solution, conception, and design obtained by equivalent replacement or change based on the technical solution and utility model concept of the utility model within the technical scope disclosed by any technician familiar with the technical field should be included in the protection scope of the utility model.
