Compared with the trouble of manually putting laundry detergent into the washing machine every time and the difficulty in controlling the amount of laundry, washing machines with "automatic dispensing" function are becoming more and more popular. However, the "automatic dispensing" function is expensive and is generally only available on high-end machines. Therefore, a hand-driven semi-automatic dispensing device has appeared, which saves the user the trouble of carrying the container to pour laundry detergent every time. By setting the amount of dispensing for each manual drive, the user can achieve the purpose of accurate dispensing by controlling the number of times the driving device is driven, making the user feel more at ease when washing, and can determine the total amount of dispensing according to the cleanliness and material of the laundry.

[0064] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0065] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0066] The following describes the dispensing device 10, dispensing assembly 100 and washing equipment 1000 according to an embodiment of the present invention with reference to the accompanying drawings. For example, the dispensing device 10 can be used in washing devices with water inlet systems such as washing machines, dishwashers, sinks or wash basins.

[0067] Reference Figure 1 and Figure 2 As shown, the dispensing device 10 according to an embodiment of the present invention is used for dispensing detergent and may include: a dispensing pump 1 and a driving component 2. The detergent may be liquid detergent such as laundry detergent and softener.

[0068] Reference Figure 1 Shown and Figure 2 As shown, the dosing pump 1 includes a pump housing 11 and a pump body 12. The pump body 12 is movably disposed in the pump housing 11. The pump housing 11 is formed with a liquid inlet 111 and a liquid outlet 112 (see Figure 8 ), the driving assembly 2 includes a driving mechanism 21 and a transmission mechanism 22, the transmission mechanism 22 is connected between the driving mechanism 21 and the pump body 12, and the driving mechanism 21 is in the first position (refer to Figure 3 as well as Figure 4 a position in the second position (refer to Figure 4 For example, the drive mechanism 21 can be movably connected to the pump housing 11. Figure 3 The driving mechanism 21 is movable between the first position and the second position. In the process of the driving mechanism 21 moving from the first position to the second position, the driving mechanism 21 drives the transmission mechanism 22 to move, so as to drive the pump body 12 to move, so as to suck the lotion from the liquid inlet 111 and discharge it from the liquid outlet 112; in the process of the driving mechanism 21 moving from the second position to the first position, the transmission mechanism 22 does not drive the pump body 12 to move, and in this process, the lotion is not put into the liquid outlet 112.

[0069] Specifically, the user can manually drive the driving mechanism 21 to move from the first position to the second position, and the driving mechanism 21 drives the transmission mechanism 22 to move, thereby driving the pump body 12 to move, so that the lotion is sucked from the liquid inlet 111 and discharged from the liquid outlet 112 (refer to Figure 8 and Fig.11 ), so as to realize semi-automatic delivery of the delivery device 10, that is, the lotion is delivered manually. When the user manually drives the driving mechanism 21 to move from the second position to the first position, the transmission mechanism 22 does not drive the pump body 12 to move, and the lotion is not delivered at the liquid outlet 112 during this process, which is beneficial to avoid the delivery pump 1 from reversely sucking the lotion through the liquid outlet 112 during the movement of the driving mechanism 21 from the second position to the first position. The accuracy of lotion delivery is high. At the same time, the transmission ratio of the transmission mechanism 22 can be reasonably set to control the movement stroke of the pump body 12, which is beneficial to increase the single delivery amount of the delivery device 10 and reduce the number of deliveries.

[0070] In view of this, according to the dispensing device 10 of the embodiment of the present invention, the driving component 2 includes a driving mechanism 21 and a transmission mechanism 22. During the process of the driving mechanism 21 moving from the first position to the second position, the driving mechanism 21 drives the transmission mechanism 22 to move, so as to drive the pump body 12 to move, so as to suck the lotion from the liquid inlet 111 and discharge it from the liquid outlet 112; during the process of the driving mechanism 21 moving from the second position to the first position, the transmission mechanism 22 does not drive the pump body 12 to move, thereby helping to avoid the dispensing pump 1 from reversely sucking the lotion through the liquid outlet 112, and the accuracy of lotion dispensing is high. At the same time, the transmission ratio of the transmission mechanism 22 can be reasonably set to control the movement stroke of the pump body 12, which is helpful to increase the single dispensing amount of the dispensing device 10 and reduce the number of dispensing times.

[0071] In some embodiments of the present invention, reference Figure 3 As shown, the drive assembly 2 further includes an elastic reset mechanism 223, which is used to drive the drive mechanism 21 to reset to the first position. It is understandable that when the user drives the drive mechanism 21 to move from the first position to the second position, the elastic reset mechanism 223 applies an elastic deformation force toward the first position to the drive mechanism 21 (refer to Figure 3 When the hand is released, the driving mechanism 21 is reset to the first position under the drive of the elastic reset mechanism 223. Figure 3 As shown, the elastic reset mechanism 223 may be a spring, and the elastic reset mechanism 223 is used to drive the driving mechanism 21 to move so as to reset to the first position.

[0072] In some embodiments of the present invention, reference Figure 2 and Figure 3As shown, the transmission mechanism 22 includes a first transmission member 221 and a second transmission member 222 that can be drivably connected. The first transmission member 221 is connected to the driving mechanism 21, and the second transmission member 222 is connected to the pump body 12. When the driving mechanism 21 moves from the first position to the second position, the first transmission member 221 and the second transmission member 222 are drivably connected. When the driving mechanism 21 moves from the second position to the first position, the first transmission member 221 and the second transmission member 222 are separated. The separation of the first transmission member 221 and the second transmission member 222 can be understood as the first transmission member 221 and the second transmission member 222 being disengaged from each other. In other words, the first transmission member 221 and the second transmission member 222 are not in contact.

[0073] It can be understood that, in the process of the driving mechanism 21 moving from the second position to the first position, by separating the first transmission member 221 from the second transmission member 222, the first transmission member 221 cannot drive the second transmission member 222 to rotate, which is beneficial to ensure that the pump body 12 does not move during this process, thereby helping to avoid the reverse suction of the lotion by the delivery pump 1 through the liquid outlet 112.

[0074] In some embodiments of the present invention, reference Figure 4 As shown, the driving mechanism 21 moves along a first path (refer to Figure 4 The drive mechanism 21 moves from the first position to the second position along a second path different from the first path (refer to Figure 4 In the embodiment of the invention, b→c→d→a) moves from the second position to the first position.

[0075] It can be understood that, in the process of the driving mechanism 21 moving from the first position to the second position, the driving mechanism 21 moves along the first path, at which time the driving mechanism 21 drives the transmission mechanism 22 to move, so as to drive the pump body 12 to move, and in the process of the driving mechanism 21 moving from the second position to the first position, the driving mechanism 21 moves along a second path different from the first path, so that the movement paths of the driving mechanism 21 when delivering the lotion and resetting are different, that is, it does not make reciprocating motion along the same path. The driving component 2 drives the pump body 12 to move in one direction, which is conducive to ensuring that the pump body 12 does not move in the process of the driving mechanism 21 moving from the second position to the first position, thereby achieving the purpose of one-way driving, and is conducive to further preventing the delivery pump 1 from reversely sucking in the lotion through the liquid outlet 112.

[0076] For example, refer to Figure 3 and Figure 4 As shown, during the process of the drive mechanism 21 moving from the first position to the second position, the drive mechanism 21 moves along the first path (refer to Figure 4In this case, the drive mechanism 21 drives the transmission mechanism 22 to move, thereby driving the pump body 12 to move. In the process of the drive mechanism 21 moving from the second position to the first position, the drive mechanism 21 moves along a second path different from the first path (refer to Figure 4 The pump body 12 moves along the path b→c→d→a) in the figure, thereby separating the first transmission member 221 and the second transmission member 222, and the driving assembly 2 cannot drive the pump body 12 to move.

[0077] In some optional embodiments of the present invention, referring to Figure 4 As shown, the first path and the second path are connected at the first position and the second position respectively to form a ring. Figure 4 As shown, the upper end of the first path is connected with the upper end of the second path at a, and the lower end of the first path is connected with the lower end of the second path at b, so that the first path and the second path form a ring. It can be understood that by connecting the first path and the second path at the first position and the second position respectively, the movement path of the driving mechanism 21 can be formed into a ring. After the driving mechanism 21 moves from the first position to the second position along the first path, the driving mechanism 21 can also return to the first position through the second path, and this reciprocation is conducive to ensuring the reliability of multiple delivery of the delivery device 10.

[0078] In some optional embodiments of the present invention, referring to Figure 4 As shown, the first path extends along a straight line, and the second path extends along a non-straight line. This is conducive to ensuring that the first path and the second path form a ring, and that the first path and the second path are connected only at the junction. It can be understood that, referring to Figure 3 and Figure 4 As shown, by making the first path a straight line, during the movement of the driving mechanism 21 from the first position to the second position, it is helpful to ensure that the first transmission member 221 and the second transmission member 222 are in a matched state, thereby ensuring that the transmission mechanism 22 can reliably drive the pump body 12 to move, thereby realizing the delivery of lotion. By extending the second path along a non-straight line, during the movement of the driving mechanism 21 from the second position to the first position, it is helpful to ensure that the first transmission member 221 and the second transmission member 222 are separated, thereby ensuring that the transmission mechanism 22 does not drive the pump body 12 to move, thereby achieving the purpose of one-way driving, which is helpful to further prevent the delivery pump 1 from reversely sucking in lotion through the liquid outlet 112.

[0079] In some optional embodiments of the present invention, referring to Figure 3 and Figure 4As shown, the delivery device 10 includes: a guide member 3, which is arranged on the driving mechanism 21, and a guide groove 113 is formed on the pump housing 11. When the driving mechanism 21 moves, the guide member 3 is driven to move along the extension direction of the guide groove 113. The guide groove 113 includes a first guide section 1131 and a second guide section 1132. The first guide section 1131 constitutes a first path, and the second guide section 1132 constitutes a second path.

[0080] It can be understood that, in the process of the driving mechanism 21 moving from the first position to the second position, the guide member 3 cooperates with the guide groove 113 and moves along the extension direction of the first guide section 1131, which can ensure that the driving mechanism 21 moves along the first path, which is beneficial to ensure that the driving mechanism 21 drives the transmission mechanism 22 to move, so as to drive the pump body 12 to move, thereby realizing the delivery of lotion; in the process of the driving mechanism 21 moving from the second position to the first position, the guide member 3 cooperates with the guide groove 113 and moves along the extension direction of the second guide section 1132, thereby ensuring that the driving mechanism 21 moves along the second path, which can ensure that the movement paths of the driving mechanism 21 are separated when delivering lotion and resetting, and no reciprocating motion is performed along the same path. The driving component 2 drives the pump body 12 to move in one direction, which is beneficial to further prevent the delivery pump 1 from reversely sucking in lotion through the liquid outlet 112. At the same time, the structure is simple and easy to implement.

[0081] For example, refer to Figure 3 As shown, for example, refer to Figure 7 As shown, the driving device 10 includes a driving shell 1184, the driving shell 1184 defines a driving cavity 1187, the driving mechanism 21 and the guide member 4 are both located in the driving cavity 1187, the guide groove 113 is formed on one side wall of the driving cavity 1187, the guide member 3 extends in the left and right directions, the guide member 3 is configured as a movable pin, and one axial end of the guide member 3 is connected to the lower end of the driving mechanism 21, and the other axial end of the guide member 3 is fitted in the guide groove 113. In the process of the driving mechanism 21 moving from the first position to the second position, the guide member 3 cooperates with the guide groove 113 and moves along the extension direction of the first guide section 1131 (refer to Figure 4 In the process of the driving mechanism 21 moving from the second position to the first position, the guide member 3 cooperates with the guide groove 113 and moves along the extension direction of the second guide section 1132 (refer to Figure 4 The first transmission member 221 and the second transmission member 222 are separated, and the driving assembly 2 cannot drive the pump body 12 to move.

[0082] In some optional embodiments of the present invention, referring to Figure 4 and Figure 7As shown, in the depth direction of the guide groove 113, the portion of the bottom wall surface of the second guide segment 1132 adjacent to the first position is higher than the portion of the bottom wall surface of the first guide segment 1131 adjacent to the first position (refer to Figure 7 ), the first guide section 1131 and the second guide section 1132 form a first step surface 1136 adjacent to the first position, a portion of the bottom wall surface of the first guide section 1131 adjacent to the second position is higher than a portion of the bottom wall surface of the second guide section 1132 adjacent to the second position, the first guide section 1131 and the second guide section 1132 form a second step surface 1137 adjacent to the second position, and the guide member 3 is disposed along the depth direction of the guide groove 113 (refer to Figure 5 and Figure 6 The driving mechanism 21 is movably arranged in the left and right directions.

[0083] Specifically, when the drive mechanism 21 is moved from the first position (refer to Figure 4 a position in the figure) towards the second position (reference Figure 4 When the guide member 3 moves toward the second guide segment 1132 (position a in the figure), at the first position, since the portion of the bottom wall surface of the second guide segment 1132 adjacent to the first position is higher than the portion of the bottom wall surface of the first guide segment 1131 adjacent to the first position in the depth direction of the guide groove 113, the first step surface 1136 will limit the movement of the guide member 3 toward the second guide segment 1132 (refer to Figure 7 ), the guide member 3 can only move along the extension direction of the first guide section 1131 (refer to Figure 4 When the guide member 3 moves to the second step surface 1137, the portion of the bottom wall surface of the first guide segment 1131 adjacent to the second position is higher than the portion of the bottom wall surface of the second guide segment 1132 adjacent to the second position in the depth direction of the guide groove 113, and the guide member 3 will "fall into" the second position (refer to Figure 4 b position in the figure), and in the process of the driving mechanism 21 moving from the first position to the second position, the driving mechanism 21 drives the transmission mechanism 22 to move, so as to drive the pump body 12 to move, thereby realizing the delivery of the lotion;

[0084] When the driving mechanism 21 moves from the second position to the first position, at the second position, the second step surface 1137 will limit the guide member 3 from returning along the first guide segment 1131, and the guide member 3 can only return along the extension direction of the second guide segment 1132 (refer to Figure 4The guide member 3 moves toward the first position along the path b→c→d→a in the figure, thereby ensuring that the driving mechanism 21 moves along the second path. When the guide member 3 passes through the second step surface 1137, the guide member 3 will "fall into" the first position, and in the process of the driving mechanism 21 moving from the second position to the first position, the transmission mechanism 22 does not drive the pump body 12 to move, and the dispensing device 10 does not dispense lotion, thereby achieving the purpose of unidirectional driving, and can reciprocate in this way, thereby ensuring that the guide member 3 moves along the first path and the second path respectively, which is beneficial to improving the reliability of the operation of the driving component 2.

[0085] Optionally, refer to Figure 7 As shown, the first step surface 1136 is perpendicular to the bottom wall surface of the first guide section 1131, so that when the driving mechanism 21 moves from the first position toward the second position, the effect of the first step surface 1136 in limiting the movement of the guide member 3 toward the second guide section 1132 can be improved, which is beneficial to ensure that the driving mechanism 21 moves from the first position toward the second position along the first guide section 1131, thereby improving the reliability of the operation of the driving component 2.

[0086] Optionally, refer to Figure 7 As shown, the second step surface 1137 is perpendicular to the bottom wall surface of the second guide section 1132, so that when the driving mechanism 21 moves from the second position toward the first position, the effect of the second step surface 1137 in limiting the movement of the guide member 3 toward the first guide section 1131 can be improved, which is beneficial to ensure that the driving mechanism 21 moves along the second guide section 1132 from the second position toward the first position, thereby improving the reliability of the operation of the driving component 2.

[0087] In some embodiments of the present invention, reference Fig. 9 and Fig.10 As shown, a mounting hole 2123 is formed on the driving mechanism 21, and the guide member 3 is movably arranged through the mounting hole 2123. Fig.10 As shown, the mounting hole 2123 penetrates the driving mechanism 21 in the left-right direction, and the guide member 3 is movably arranged in the mounting hole 2123 in the left-right direction. As a result, the structure is simple, and it is convenient to ensure that the guide member 3 is movably arranged on the driving mechanism 21 along the depth direction of the guide groove 113. Optionally, the guide member 3 is formed into a cylindrical shape, and the mounting hole 2123 is also formed into a circular hole, thereby increasing the matching area between the guide member 3 and the mounting hole 2123, which is conducive to ensuring the reliability of the guide member 3 moving along the depth direction of the guide groove 113.

[0088] In some optional embodiments of the present invention, the guide member 3 is kept in contact with the bottom wall surface of the guide groove 113. Fig. 9 and 10As shown, one axial end of the guide member 3 keeps in contact with the bottom wall surface of the guide groove 113. Therefore, when the guide member 3 moves in the guide groove 113, it is helpful to ensure the reliability of the cooperation between the guide member 3 and the guide groove 113.

[0089] Specifically, refer to Figure 3 and Figure 4 As shown, when the driving mechanism 21 moves from the first position to the second position, at the first position, since in the depth direction of the guide groove 113, the portion of the bottom wall surface of the second guide segment 1132 adjacent to the first position is higher than the portion of the bottom wall surface of the first guide segment 1131 adjacent to the first position, the first step surface 1136 will restrict the guide member 3 from moving toward the second guide segment 1132, and the guide member 3 can only move along the extension direction of the first guide segment 1131 (refer to Figure 4 During this process, the guide member 3 keeps in contact with the bottom wall of the first guide segment 1131, thereby improving the reliability of the cooperation between the guide member 3 and the first guide segment 1131. When the guide member 3 moves to the second step surface 1137, since in the depth direction of the guide groove 113, the portion of the bottom wall of the first guide segment 1131 adjacent to the second position is higher than the portion of the bottom wall of the second guide segment 1132 adjacent to the second position, the guide member 3 will "fall into" the second position, and in the process of the drive mechanism 21 moving from the first position to the second position, the drive mechanism 21 drives the transmission mechanism 22 to move, so as to drive the pump body 12 to move, thereby realizing the delivery of the lotion;

[0090] When the driving mechanism 21 moves from the second position to the first position, at the second position, the second step surface 1137 will limit the guide member 3 from returning along the first guide segment 1131, and the guide member 3 can only return along the extension direction of the second guide segment 1132 (refer to Figure 4 During this process, the guide member 3 maintains contact with the bottom wall surface of the second guide segment 1132, thereby improving the reliability of the cooperation between the guide member 3 and the second guide segment 1132, which is beneficial to ensure that the drive mechanism 21 moves along the second path. When the guide member 3 passes through the second step surface 1137, the guide member 3 will "fall into" the first position, and in the process of the drive mechanism 21 moving from the second position to the first position, the transmission mechanism 22 does not drive the pump body 12 to move, and the dispensing device 10 does not dispense lotion, thereby achieving the purpose of unidirectional drive, and can reciprocate in this way, thereby ensuring that the guide member 3 moves along the first path and the second path respectively, and improving the reliability of the operation of the drive component 2.

[0091] In some optional embodiments of the present invention, referring to Fig. 9As shown, the drive mechanism 21 is provided with an elastic retainer 34, which exerts elastic force on the guide member 3 so that the guide member 3 remains in contact with the bottom wall of the guide groove 113. Thus, when the drive mechanism 21 moves between the first position and the second position, it is beneficial to ensure that the guide member 3 is always in contact with the bottom wall of the guide groove 113.

[0092] For example, refer to Fig. 9 As shown, the drive mechanism 21 is provided with a mounting hole 2123, and the mounting hole 2123 includes a first hole section 2124 and a second hole section 2125 that are connected to each other. The cross-sectional area of ​​the first hole section 2124 is larger than the cross-sectional area of ​​the second hole section 2125. The guide member 3 includes an abutment portion 31, a stop portion 32 and a guide portion 33 that are connected in sequence. The cross-sectional area of ​​the stop portion 32 is larger than the cross-sectional area of ​​the guide portion 33. The elastic retaining member 34 is connected between the stop portion 32 and a side wall of the first hole section 2124 close to the second hole section 2125. The stop portion 32 is movably provided in the first hole section 2124, and the guide portion 33 is movably penetrated in the second hole section 2125. The elastic retaining member 34 has an elastic force on the stop portion 32, so that the abutment portion 31 remains in contact with the bottom wall surface of the guide groove 113.

[0093] Specifically, when the driving mechanism 21 moves from the first position to the second position, at the first position, since the portion of the bottom wall surface of the second guide segment 1132 adjacent to the first position is higher than the portion of the bottom wall surface of the first guide segment 1131 adjacent to the first position in the depth direction of the guide groove 113, the first step surface 1136 will restrict the guide member 3 from moving toward the second guide segment 1132, and the guide member 3 can only move along the extension direction of the first guide segment 1131 (refer to Figure 4 1131), during which the elastic retainer 34 is in a compressed state, and the elastic retainer 34 often pushes the stopper 32, so that the guide member 3 keeps in contact with the bottom wall surface of the first guide section 1131, thereby improving the reliability of the cooperation between the guide member 3 and the first guide section 1131. When the guide member 3 moves to the second step surface 1137, since in the depth direction of the guide groove 113, the portion of the bottom wall surface of the first guide section 1131 adjacent to the second position is higher than the portion of the bottom wall surface of the second guide section 1132 adjacent to the second position, the guide member 3 will "fall into" the second position, and in the process of the drive mechanism 21 moving from the first position to the second position, the drive mechanism 21 drives the transmission mechanism 22 to move, so as to drive the pump body 12 to move, thereby realizing the delivery of the lotion;

[0094] When the driving mechanism 21 moves from the second position to the first position, at the second position, the second step surface 1137 will limit the guide member 3 from returning along the first guide segment 1131, and the guide member 3 can only return along the extension direction of the second guide segment 1132 (refer to Figure 4The guide member 3 moves along the path of (b→c→d→a) in the middle toward the first position. During this process, the elastic retaining member 34 is in a compressed state. The elastic retaining member 34 often pushes the guide member 3 so that the guide member 3 maintains contact with the bottom wall surface of the second guide section 1132, thereby improving the reliability of the cooperation between the guide member 3 and the second guide section 1132, which is beneficial to ensure that the driving mechanism 21 moves along the second path. When the guide member 3 passes through the second step surface 1137, the guide member 3 will "fall into" the first position, and in the process of the driving mechanism 21 moving from the second position to the first position, the transmission mechanism 22 does not drive the pump body 12 to move, and the dispensing device 10 does not dispense lotion, thereby achieving the purpose of unidirectional driving, and can reciprocate in this way, thereby ensuring that the guide member 3 moves along the first path and the second path respectively, improving the reliability of the operation of the driving component 2.

[0095] In some embodiments of the present invention, reference Fig.10 As shown, a profile member 1191 is provided on the side of the pump housing 11 opposite to the bottom wall of the guide groove 113. For example, the profile member 1191 can be defined by a partial structure of the pump housing 11. The wall surface of the profile member 1191 facing the guide groove 113 is formed as a profile surface 1192 adapted to the bottom wall surface of the guide groove 113. The guide member 3 is in contact with the bottom wall surface of the guide groove 113 and the profile surface 1192. It can be understood that the guide member 3 can be kept in contact with the bottom wall surface of the guide groove 113 only by the constraints of the profiles of the guide groove 113 and the profile surface 1192, without the need to provide other elastic auxiliary structures, and the structure is simple and easy to implement.

[0096] In some embodiments of the present invention, reference Figure 5 and Figure 7 As shown, at least a portion of the bottom wall of the second guide section 1132 adjacent to the first position forms a first transition surface 1138, the first transition surface 1138 is connected to the first step surface 1136, and the first transition surface 1138 gradually increases in height in the direction from the second position to the first position (refer to Figure 5 ), whereby, in the process of the guide member 3 moving from the second position to the first position along the second guide section 1132, the guide member 3 can be guided to the first step surface 1136 through the first transition surface 1138, which is beneficial to prevent the guide member 3 from getting stuck and improve the reliability of the driving assembly 2.

[0097] Reference Figure 6 and Figure 7As shown, at least the portion of the bottom wall surface of the first guide section 1131 adjacent to the second position constitutes a second transition surface 1139, the second transition surface 1139 is connected to the second step surface 1137, and the second transition surface 1139 gradually increases in the direction from the first position to the second position. Therefore, when the guide member 3 moves from the first position to the second position along the first guide section 1131, the guide member 3 can be guided to the second step surface 1137 through the second transition section, which is conducive to preventing the guide member 3 from getting stuck and improving the reliability of the driving assembly 2.

[0098] For example, a portion of the bottom wall surface of the second guide section 1132 adjacent to the first position constitutes a first transition surface 1138, which is connected to the first step surface 1136, and the first transition surface 1138 gradually increases in height and smoothly transitions in the direction from the second position to the first position; a portion of the bottom wall surface of the first guide section 1131 adjacent to the second position constitutes a second transition surface 1139, which is connected to the second step surface 1137, and the second transition surface 1139 gradually increases in height and smoothly transitions in the direction from the first position to the second position.

[0099] Specifically, when the driving mechanism 21 moves from the first position to the second position, at the first position, since the portion of the bottom wall surface of the second guide segment 1132 adjacent to the first position is higher than the portion of the bottom wall surface of the first guide segment 1131 adjacent to the first position in the depth direction of the guide groove 113, the first step surface 1136 will restrict the guide member 3 from moving toward the second guide segment 1132, and the guide member 3 can only move along the extension direction of the first guide segment 1131 (refer to Figure 4 In the process, the second transition surface 1139 is connected to the second step surface 1137, and the second transition surface 1139 gradually increases in height in the direction from the first position to the second position. The second transition section can guide the guide member 3 to the second step surface 1137. When the guide member 3 moves to the second step surface 1137, since the bottom wall of the first guide section 1131 adjacent to the second position is higher than the bottom wall of the second guide section 1132 adjacent to the second position in the depth direction of the guide groove 113, the guide member 3 will "fall into" the second position, and in the process of the driving mechanism 21 moving from the first position to the second position, the driving mechanism 21 drives the transmission mechanism 22 to move, so as to drive the pump body 12 to move, thereby realizing the delivery of the lotion;

[0100] When the driving mechanism 21 moves from the second position to the first position, at the second position, the second step surface 1137 will limit the guide member 3 from returning along the first guide segment 1131, and the guide member 3 can only return along the extension direction of the second guide segment 1132 (refer to Figure 4The guide member 3 moves along the path b→c→d→a in the figure) toward the first position, during which the guide member 3 is connected with the first step surface 1136 through the first transition surface 1138, and the first transition surface 1138 gradually increases in the direction from the second position to the first position. The first transition section can guide the guide member 3 to the first step surface 1136, and when the guide member 3 passes through the first step surface 1136, the guide member 3 will "fall into" the first position, and in the process of the driving mechanism 21 moving from the second position to the first position, the transmission mechanism 22 does not drive the pump body 12 to move, and the dispensing device 10 does not dispense lotion, thereby achieving the purpose of unidirectional driving, and can reciprocate in this way, thereby ensuring that the guide member 3 moves along the first path and the second path respectively, which is beneficial to improving the reliability of the driving component 2.

[0101] In some embodiments of the present invention, reference Figure 3 , Figure 4 and Figure 7 As shown, a limiting protrusion 114 is also formed on the bottom wall of the second guide segment 1132, and the limiting protrusion 114 is located between the first guide segment 1131 and the second guide segment 1132. Both ends of the limiting protrusion 114 are spaced apart from the side wall of the guide groove 113 and define a first connecting gap 115 and a second connecting gap 116 connecting the first guide segment 1131 and the second guide segment 1132. For example, Figure 4 As shown, the limiting protrusion 114 extends in the up-down direction. In the front-back direction, the limiting protrusion 114 is located between the first guide section 1131 and the second guide section 1132. The upper end of the limiting protrusion 114 is spaced apart from the upper side wall of the guide groove 113 to define a first connecting gap 115. The lower end of the limiting protrusion 114 is spaced apart from the lower side wall of the guide groove 113 to define a second connecting gap 116. It can be understood that after the guide member 3 moves from the first position to the second position along the first guide section 1131, the guide member 3 can enter the second guide section 1132 through the second connecting gap 116, and after the guide member 3 moves from the first position to the second position along the second guide section 1132, the guide member 3 can enter the first guide section 1131 through the first connecting gap 115, and reciprocate in this way. Therefore, the limiting protrusion 114 can separate the unconnected parts of the first guide section 1131 and the second guide section 1132, which is conducive to ensuring the reliability of the guide member 3 moving in the first guide section 1131 and the second guide section 1132 respectively.

[0102] In some embodiments of the present invention, reference Figure 4As shown, the first guide segment 1131 extends in a straight line, and in the direction from the second position to the first position, the second guide segment 1132 includes a first sub-guide segment 1133, a second sub-guide segment 1134 and a third sub-guide segment 1135 arranged in sequence, the second sub-guide segment 1134 is parallel to the first guide segment 1131, and the second sub-guide segment 1134 has an angle with the first sub-guide segment 1133 and the third sub-guide segment 1135, and the angle is an obtuse angle. It can be understood that, referring to Figure 3 and Figure 4 As shown, by making the first guide segment 1131 extend along a straight line, in the process of the driving mechanism 21 moving from the first position to the second position, it is beneficial to ensure that the first transmission member 221 and the second transmission member 222 are in a matched state, and it is beneficial to ensure that the transmission mechanism 22 can reliably drive the pump body 12 to move, thereby realizing the delivery of lotion. The second guide segment 1132 includes a first sub-guide segment 1133, a second sub-guide segment 1134 and a third sub-guide segment 1135 arranged in sequence, and the second sub-guide segment 1134 is parallel to the first guide segment 1131, and there is an angle between the second sub-guide segment 1134 and the first sub-guide segment 1133 and the third sub-guide segment 1135, and the angle is an obtuse angle. In the process of the driving mechanism 21 moving from the second position to the first position, it is beneficial to ensure that the first transmission member 221 and the second transmission member 222 are separated, thereby ensuring that the transmission mechanism 22 does not drive the pump body 12 to move, thereby achieving the purpose of unidirectional drive.

[0103] In some embodiments of the present invention, reference Figure 3 As shown, the driving mechanism 21 includes a first driving member 211 and a second driving member 212, the guide member 3 is arranged on the second driving member 212, the transmission mechanism 22 is connected between the second driving member 212 and the pump body 12, the first driving member 211 is movable between the first position and the second position, and in the process of the first driving member 211 moving from the first position to the second position, the first driving member 211 drives the second driving member 212 to move. It can be understood that by making the first driving member 211 movable between the first position and the second position, the movement trajectory of the first driving member 211 can be ensured to be a straight line, which is conducive to ensuring the reliability of the movement of the driving mechanism 21.

[0104] In some optional embodiments of the present invention, reference Figure 3As shown, the second driving member 212 is rotatably connected to the first driving member 211. For example, the second driving member 212 can be rotatably connected to the first driving member 211 via a rotating shaft 2121. Thus, during the movement of the first driving member 211 from the first position to the second position, the second driving member 212 can rotate relative to the first driving member 211, and the movement state of the second driving member 212 can be controlled by controlling the movement path of the guide member 3, so that the second driving member 212 can control whether the transmission mechanism 22 drives the pump body 12 to move, which is conducive to improving the reliability of the one-way drive.

[0105] In some embodiments of the present invention, reference Figure 3 As shown, the first driving member 211 is formed with a guide hole 2111 extending in an arc shape, and the second driving member 212 is formed with a guide column 2122 cooperating with the guide hole 2111. When the second driving member 212 rotates relative to the first driving member 211, the guide column 2122 moves along the extension direction of the guide hole 2111. For example, as shown in reference 3, the guide hole 2111 is formed as an arc hole, and through the cooperation between the guide column 2122 and the guide hole 2111, the maximum rotation angle of the second driving member 212 is α. It can be understood that by moving the guide column 2122 along the extension direction of the guide hole 2111, the maximum rotation angle of the first driving member 211 can be limited, which is conducive to ensuring the reliability of the rotation of the second driving member 212 and preventing the driving assembly 2 from working abnormally.

[0106] In some embodiments of the present invention, reference Figure 3 As shown, the drive assembly 2 also includes an elastic reset mechanism 223, and the elastic reset mechanism 223 includes a first elastic reset member 2231 for driving the first drive member 211 to reset to the first position. It can be understood that when the user drives the drive mechanism 21 to move from the first position to the second position, the first elastic reset member 2231 applies an elastic deformation force toward the first position to the first drive member 211, and when the hand is released, the first drive member 211 is reset to the first position under the drive of the first elastic reset member 2231. For example, the first elastic reset member 2231 can be a spring, and the first elastic reset member 2231 is used to drive the drive mechanism 21 to move to reset to the first position. Of course, the present invention is not limited to this, and the drive assembly 2 may also not include the first elastic reset member, and the first drive member 211 is driven manually to return to the first position.

[0107] Specifically, when the user drives the first driving member 211 to move from the first position to the second position, at the first position, since in the depth direction of the guide groove 113, the portion of the bottom wall surface of the second guide segment 1132 adjacent to the first position is higher than the portion of the bottom wall surface of the first guide segment 1131 adjacent to the first position, the first step surface 1136 will restrict the guide member 3 from moving toward the second guide segment 1132, and the guide member 3 can only move along the extension direction of the first guide segment 1131 (refer to Figure 4 The second driving member 212 moves along the path a→b in the drawing. At this time, the motion trajectory of the second driving member 212 is a straight line. The second driving member 212 drives the driving mechanism 21 to move, thereby driving the pump body 12 to move, thereby achieving the delivery of the lotion. When the guide member 3 moves to the second step surface 1137, since the bottom wall of the first guide segment 1131 adjacent to the second position is higher than the bottom wall of the second guide segment 1132 adjacent to the second position in the depth direction of the guide groove 113, the guide member 3 will "fall into" the second position. At the same time, during this process, the first elastic reset mechanism 2231 is compressed.

[0108] When the user's driving force is cancelled, the first driving member 211 moves from the second position to the first position under the drive of the first elastic reset mechanism 2231. At the second position, the second step surface 1137 restricts the guide member 3 from returning along the first guide segment 1131, and the guide member 3 can only return along the extension direction of the second guide segment 1132 (refer to Figure 4 The guide member 3 moves toward the first position (the path b→c→d→a in the figure), so as to ensure that the driving mechanism 21 moves along the second path. At this time, the guide member 3 drives the second driving member 212 to rotate, and the movement trajectory of the second driving member 212 is an arc. The transmission mechanism 22 does not drive the pump body 12 to move, and the dispensing device 10 does not dispense lotion, thereby achieving the purpose of unidirectional driving. When the guide member 3 passes through the second step surface 1137, the guide member 3 will "fall into" the first position.

[0109] In some optional embodiments of the present invention, referring to Fig.12 As shown, the pump housing 11 is also formed with a moving direction of the first driving member 211 (refer to Figure 1 The slide groove 1193 ( Fig.12 The dashed line in the middle indicates the slide groove extending in the up-down direction), the second driving member 212 is provided with a sliding member 2126, the sliding member 2126 is rotatably arranged in the slide groove 1193 and can move along the extension direction of the slide groove 1193, and the first driving member 211 and the second driving member 212 are in the moving direction of the first driving member 211. Therefore, the first driving member 211 and the second driving member 212 can be set as separate members, and the first driving member 211 and the second driving member 212 do not need to be connected by a rotating shaft structure, which is conducive to simplifying the structure of the driving mechanism 21. For example, referring to Fig.12As shown, the sliding member 2126 is formed into a cylindrical shape, one axial end of the sliding member 2126 is fixed to the upper end of the second driving member 212, and the other axial end of the sliding member 2126 is matched to the slide groove 1193, the slide groove 1193 is formed as a strip groove and extends in the up and down directions, and the sliding member 2126 is rotatably and movably connected to the slide groove 1193.

[0110] In some embodiments of the present invention, the driving assembly 2 further includes an elastic reset mechanism 223, and the elastic reset mechanism 223 includes a second elastic reset member 2232, and the second elastic reset member 2232 is used to drive the second driving member 212 to reset. It can be understood that when the user drives the driving mechanism 21 to move from the first position to the second position, the second elastic reset member 2232 applies an elastic deformation force toward the first position to the second driving member 212. When the user releases the hand, the second driving member 212 drives the first driving member 211 to reset to the first position under the drive of the second elastic reset member 2232. For example, referring to Fig.12 As shown, the second elastic reset member 2232 can be a spring. The second elastic reset member 2232 is connected between the bottom wall of the slide groove 1193 and the sliding member 2126. The second elastic reset member 2232 is used to drive the second driving member 212 to move to reset to the first position.

[0111] Specifically, when the user drives the first driving member 211 to move from the first position to the second position, at the first position, since in the depth direction of the guide groove 113, the portion of the bottom wall surface of the second guide segment 1132 adjacent to the first position is higher than the portion of the bottom wall surface of the first guide segment 1131 adjacent to the first position, the first step surface 1136 will restrict the guide member 3 from moving toward the second guide segment 1132, and the guide member 3 can only move along the extension direction of the first guide segment 1131 (refer to Figure 4 At the same time, since the sliding member 2126 moves along the slide groove 1193, the movement trajectory of the second driving member 212 is a straight line, and the first transmission member 221 and the second transmission member 222 remain in meshing to drive the pump body 12 to move, thereby realizing the delivery of the lotion. When the guide member 3 moves to the second step surface 1137, since in the depth direction of the guide groove 113, the bottom wall surface of the first guide section 1131 adjacent to the second position is higher than the bottom wall surface of the second guide section 1132 adjacent to the second position, the guide member 3 will "fall into" the second position. At the same time, in this process, the second elastic reset mechanism 2232 is compressed;

[0112] When the user's driving force F is canceled, under the drive of the second elastic reset mechanism 2232, the second driving member 212 pushes the first driving member 211 to move from the second position to the first position. At the second position, the second step surface 1137 restricts the guide member 3 from returning along the first guide segment 1131, and the guide member 3 can only return along the extension direction of the second guide segment 1132 (refer to Figure 4 The guide member 3 drives the second driving member 212 to rotate relative to the slide groove 1193, and the movement trajectory of the first driving member 211 is an arc. The transmission mechanism 22 does not drive the pump body 12 to move, and the dispensing device 10 does not dispense lotion, thereby achieving the purpose of one-way driving, and when the guide member 3 passes through the second step surface 1137, the guide member 3 will "fall into" the first position.

[0113] In some specific embodiments of the present invention, referring to Figure 3 As shown, the transmission mechanism 22 includes a first transmission member 221 and a second transmission member 222 that can be connected in a transmission manner. The first transmission member 221 is connected to the second driving member 212, and the second transmission member 222 is connected to the pump body 12. In the process of the first driving member 211 moving from the first position to the second position, the first transmission member 221 and the second transmission member 222 are connected in a transmission manner. In the process of the first driving member 211 moving from the second position to the first position, the first transmission member 221 is separated from the second transmission member 222. It can be understood that in the process of the driving mechanism 21 moving from the second position to the first position, by separating the first transmission member 221 from the second transmission member 222, the first transmission member 221 cannot drive the second transmission member 222 to rotate, which is conducive to ensuring that the pump body 12 does not move during this process, thereby helping to prevent the delivery pump 1 from reversely sucking in lotion through the liquid outlet 112.

[0114] In some embodiments of the present invention, reference Figure 3 As shown, the first transmission member 221 is a rack extending in the direction from the first position to the second position, and the second transmission member 222 is a gear. Figure 4 As shown, the first transmission member 221 includes a plurality of matching teeth, and the plurality of matching teeth are arranged on the second driving member 212 at intervals in the vertical direction. The second transmission member 222 is suitable for meshing with the plurality of matching teeth. Figure 8 As shown, the pump body 12 includes two sub-pump bodies 121 meshing with each other, wherein a portion of the sub-pump body 121 passes through the pump housing 11 and is fixedly connected to the second transmission member 222, and the rotation axis of the sub-pump body 121 and the rotation axis of the second transmission member 222 are on the same straight line. It can be understood that since the motion trajectory of the first driving member 221 is a straight line, and the first transmission member 221 is a rack extending in the direction from the first position to the second position, it is helpful to improve the reliability of the cooperation between the first transmission member 221 and the second transmission member 222 during the movement of the first driving member 221 from the first position to the second position, thereby extending the service life of the delivery device 10.

[0115] Specifically, refer to Figure 4As shown, when the user drives the first driving member 211 to move from the first position toward the second position, at the first position, since in the depth direction of the guide groove 113, the portion of the bottom wall surface of the second guide segment 1132 adjacent to the first position is higher than the portion of the bottom wall surface of the first guide segment 1131 adjacent to the first position, the first step surface 1136 will restrict the guide member 3 from moving toward the second guide segment 1132, and the guide member 3 can only move along the extension direction of the first guide segment 1131 (refer to Figure 4 113a and 113b), at this time, the motion trajectory of the second driving member 212 is a straight line, the first transmission member 221 and the second transmission member 222 are kept in meshing, so as to drive the pump body 12 to move, thereby realizing the delivery of lotion, when the guide member 3 moves to the second step surface 1137, because in the depth direction of the guide groove 113, the bottom wall surface of the first guide section 1131 adjacent to the second position is higher than the bottom wall surface of the second guide section 1132 adjacent to the second position, the guide member 3 will "fall into" the second position, and at the same time, in this process, the first elastic reset mechanism 2231 is compressed;

[0116] When the user's driving force F is withdrawn, the first driving member 211 moves from the second position toward the first position under the drive of the first elastic reset mechanism 2231. At the second position, the second step surface 1137 restricts the guide member 3 from returning along the first guide segment 1131, and the guide member 3 can only return along the extension direction of the second guide segment 1132 (refer to Figure 4 The guide member 3 moves toward the first position (the path of b→c→d→a in the figure). When the guide member 3 passes the second step surface 1137, the guide member 3 will "fall into" the first position. Thus, the driving mechanism 21 can be ensured to move along the second path. At this time, the guide member 3 drives the second driving member 212 to rotate. The movement trajectory of the second driving member 212 is an arc, and the first transmission member 221 and the second transmission member 222 are disengaged. The transmission mechanism 22 does not drive the pump body 12 to move, and the dispensing device 10 does not dispense lotion, thereby achieving the purpose of unidirectional driving.

[0117] In some embodiments of the present invention, reference Figure 2 and Figure 3The pump body 12 shown is rotatably disposed in the pump housing 11 so that a liquid suction area 1111 and a liquid discharge area 1112 are formed in the pump housing 1111, and a liquid inlet 111 corresponding to the liquid suction area 1111 and a liquid outlet 112 corresponding to the liquid discharge area 1112 are formed on the pump housing 11. It can be understood that when the dispensing device 10 is in the initial state, there is no lotion in the discharge area 1112. When the mobile driving member drives the pump body 12 to rotate, negative pressure can be generated in the liquid suction area 1111 and positive pressure can be generated in the liquid discharge area 1112. The lotion at the liquid inlet 111 flows to the liquid discharge area 1112 under the action of the pressure difference. During this process, the liquid suction at the liquid inlet 111 and the liquid discharge at the liquid outlet 112 of the dispensing pump 1 are not synchronized in time until the lotion can be discharged from the liquid outlet 112. After that, that is, when the dispensing device 10 is working normally, when the driving mechanism 21 moves from the first position to the second position to dispense the lotion, the liquid suction at the liquid inlet 111 and the liquid discharge at the liquid outlet 112 of the dispensing pump 1 are synchronized in time.

[0118] The inventor found in actual research that the principle of the manual dispensing device in the related art is to use a reciprocating motion device similar to a plunger pump to change the volume ratio of the extraction and discharge device cavities to achieve liquid suction and discharge, and the liquid suction action and liquid discharge action are performed alternately. In other words, the liquid suction and liquid discharge of the manual dispensing device in the related art are located in the same area and are not synchronized in time. The liquid discharge force is provided by manual pressure, and the power required for liquid extraction is provided by spring reset, which is similar to the pressing dispensing device of shampoo or hand sanitizer in daily life. However, due to the large capacity of washing equipment such as washing machines and dishwashers, the amount of detergent required for each washing is much greater than the single use of hand sanitizer or shampoo in daily life. This requires making the pump cavity larger, or asking the user to press more times, which will lead to a worse user experience.

[0119] The dispensing device according to the embodiment of the present invention can achieve quantitative control of the amount of detergent dispensed by controlling the movement stroke of the driving component 2, and because the suction area 1111 and the discharge area 1112 of the dispensing pump 1 are located in different areas, when the dispensing device 10 works normally, the suction at the liquid inlet 111 and the discharge at the liquid outlet 112 of the dispensing pump 1 are synchronized in time, so that the dispensing amount of the dispensing pump 1 is not limited by the volume of the dispensing pump 1, which is beneficial to increase the amount of detergent dispensed by the dispensing device 10 at a time, and then on the basis of a certain volume of the dispensing device 10, the single dispensing amount of the dispensing device 10 can be increased and the dispensing accuracy of the single dispensing can be guaranteed, which is beneficial to reducing the number of dispensing times and ensuring the accuracy requirements, and can adapt to the requirements of large-capacity washing equipment 1000 such as washing machines and dishwashers for detergent dispensing, and is beneficial to improving the user experience.

[0120] Optionally, in some examples, reference Figure 1 and Figure 2As shown, the pump housing 11 includes a housing portion 1181 and an end cover 1182. The end cover 1182 is detachably disposed at the open end of the housing portion 1181. A relatively sealed pump chamber 1183 is defined between the housing portion 1181 and the end cover 1182 (see Figure 3 ), the pump body 12 is rotatably disposed in the pump chamber 1183. It is understood that by making the end cover 1182 detachably disposed at the open end of the housing portion 1181, it is convenient to install and replace the pump body 12. For example, the end cover 1182 can be connected to the housing portion 1181 by means of snap connection, riveting or threaded fastener connection.

[0121] In some embodiments of the present invention, reference Figure 8 As shown, the pump body 12 includes two rotatable and mutually meshing sub-pump bodies 121, for example, the rotation axes of the two sub-pump bodies 121 extend in the horizontal direction. It can be understood that by making the pump body 12 include two rotatable and mutually meshing sub-pump bodies 121, it is helpful to improve the working reliability of the delivery pump 1, and when the delivery pump 1 is not working, it is helpful to avoid leakage of the delivery pump 1.

[0122] Or, refer to Fig.13 As shown, the pump body 12 is an impeller pump 14. It is understood that the impeller pump 14 can drive the liquid to rotate at a high speed, transfer mechanical energy to the liquid, and thus achieve the purpose of conveying the liquid. For example, the impeller pump 14 can be a centrifugal or axial flow impeller pump.

[0123] In some optional embodiments of the present invention, referring to Figure 3 and Fig.13 As shown, the pump body 12 includes two rotatable and externally meshed sub-pump bodies 121, and the sub-pump bodies 121 are gears (refer to Figure 3 ) or screw (refer to Fig.13 ). Thus, the structure is simple, which is conducive to further improving the reliability of the pump body 12 and ensuring the accuracy of single delivery. Of course, the present invention is not limited to this. The pump body 12 can also be replaced by two rotatable and internally meshing gear pump bodies. For example, the pump body 12 can include an internal gear and an external gear. The external gear is located inside the internal gear and is eccentrically arranged relative to the internal gear. The drive assembly 2 can be connected to the external gear, and the movement of the drive mechanism 21 drives the transmission mechanism 22 to drive the external gear to rotate. The external gear drives the internal gear to rotate, thereby driving the lotion in the pump housing 11 to flow, so as to generate negative pressure at the liquid inlet 111 and positive pressure at the liquid outlet 112. The lotion in the liquid suction area 1111 flows to the liquid discharge area 1112 under the action of the pressure difference and is discharged through the liquid outlet 112 to achieve the delivery of the lotion.

[0124] In some optional embodiments of the present invention, referring to Fig.14As shown, the pump body 12 is an impeller pump 14, and a mounting cavity 13 with a circular cross section is defined in the pump housing 11. The impeller pump 14 includes: a wheel disc 141 and a plurality of blades 142. The wheel disc 141 is rotatably disposed in the mounting cavity 13. The wheel disc 141 is eccentrically disposed relative to the mounting cavity 13. A suction and discharge cavity 131 is defined between the outer peripheral wall of the wheel disc 141 and the inner peripheral wall of the mounting cavity 13. The suction and discharge cavity 131 includes a liquid suction area 1111 and a liquid discharge area 1112. A plurality of blades 142 are spaced apart in the circumferential direction of the wheel disc 141. One end of each blade 142 is connected to the wheel disc 141 and the other end is elastically stopped against the inner peripheral wall of the mounting cavity 13. For example, Fig.12 As shown, one end of each blade 142 is connected to the wheel disc 141 through a spring member 143, so that the other end of each blade 142 elastically stops against the inner circumferential wall of the installation cavity 13. When the driving component 2 drives the impeller pump 14 to rotate clockwise, the blade 142 drives the rotation of the liquid in the installation cavity 13. Due to the eccentric setting of the wheel disc 141, a negative pressure is generated at the liquid inlet 111, which has the effect of sucking liquid, and a positive pressure is generated at the liquid outlet 112, so that the liquid is squeezed out at the liquid outlet 112, which has the effect of discharging liquid.

[0125] It can be understood that the amount of lotion dosed can be controlled by controlling the movement stroke of the driving mechanism 21, and since the suction and discharge of the dosing pump 1 are synchronized in time, the amount of the dosing pump 1 is not limited by the volume of the dosing pump 1, the single dosing amount of the dosing device 10 can be increased and the dosing accuracy of the single dosing can be guaranteed. At the same time, since one end of each blade 142 is connected to the wheel disc 141 and the other end is elastically stopped against the inner circumferential wall of the installation cavity 13, reliable liquid intake and discharge of the dosing pump 1 can be guaranteed, and when the impeller pump 14 stops working, the other end of each blade 142 is elastically stopped against the inner circumferential wall of the installation cavity 13 to achieve closure, which is beneficial to avoid leakage of the dosing device 10.

[0126] In some embodiments of the present invention, reference Fig.12 As shown, the delivery device 10 further includes a cylindrical mounting seat 15, which is disposed in the pump housing 11 and fixed relative to the pump housing 11, and a mounting cavity 13 is formed in the mounting seat 15, and the mounting cavity 13 is eccentrically disposed relative to the mounting seat 15. It can be understood that by making the mounting seat 15 and the pump housing 11 separate, it is helpful to reduce the difficulty of processing the mounting seat 15 and the pump housing 11 respectively, and reduce the mold opening cost.

[0127] Reference Figure 1 and Figure 2 As shown, the delivery assembly 100 according to the embodiment of the present invention comprises: a delivery device 10 and a storage box 20 for storing lotion, the delivery device 10 is the delivery device 10 according to the above embodiment of the present invention, and the storage box 20 defines a storage cavity 201, and the storage cavity 201 is connected to the liquid inlet 111. For example, referring to Figure 1As shown, the storage box 20 is located above the dispensing device 10, and the lotion in the storage box 20 can flow toward the liquid inlet 111 under the action of gravity.

[0128] According to the dispensing component 100 of the embodiment of the present invention, by setting the dispensing device 10 according to the above-mentioned embodiment of the present invention, it is beneficial to avoid the dispensing pump 1 from reversely sucking in the lotion through the liquid outlet 112, and the accuracy of lotion dispensing can be improved. At the same time, the transmission ratio of the transmission mechanism 22 can be reasonably set to control the movement stroke of the pump body 12, which is beneficial to increase the single dispensing amount of the dispensing device 10 and reduce the number of dispensing times.

[0129] In some embodiments of the present invention, reference Figure 1 and Figure 2 As shown, the storage box 20 is arranged on the pump housing 11. This is conducive to reducing the overall space occupied by the storage box 20 and the pump housing 11, and is conducive to miniaturization of the delivery assembly 100; or, in other embodiments, the storage box 20 is connected to the pump housing 11 through a connecting pipe, thereby facilitating the connection, and the storage box 20 and the pump housing 11 can be arranged separately, which can improve the flexibility of the installation of the delivery assembly 100.

[0130] In some embodiments of the present invention, the storage box 20 is disposed on the pump housing 11, and the storage box 20 is detachably connected to the pump housing 11. It is understandable that the storage box 20 and the pump housing 11 are detachably connected, which facilitates the replacement or maintenance of the storage box 20 and the pump housing 11, which helps to reduce maintenance costs. Figure 1 and Figure 2 As shown, the storage box 20 and the end cover 1182 are an integrally formed part. The integral part formed by the storage box 20 and the end cover 1182 is arranged at the right end of the shell part 1181 and is detachably connected to the shell part 1181.

[0131] Optionally, in some examples, reference Figure 2 As shown, the integrated piece formed by the storage box 20 and the end cap 1182 is connected to the housing portion 1181 through a threaded fastener. It can be understood that the threaded fastener has the advantages of simple structure and easy assembly. The threaded fastener can achieve a tight connection between the integrated piece formed by the storage box 20 and the end cap 1182 and the housing portion 1181. In addition, the cost can be reduced while ensuring the connection strength between the integrated piece formed by the storage box 20 and the end cap 1182 and the housing portion 1181. Optionally, the threaded fastener can be a screw, a bolt, or a stud.

[0132] Alternatively, in other embodiments, the storage box 20 is integrally formed with the pump housing 11. It is understandable that the integrally formed structure can not only ensure the structural and performance stability of the storage box 20 and the pump housing 11, but also facilitate molding and simple manufacturing, and eliminate unnecessary assembly parts and connection processes, greatly improving the assembly efficiency of the storage box 20 and the pump housing 11, and ensuring the reliability of the connection between the storage box 20 and the pump housing 11. Furthermore, the overall strength and stability of the integrally formed structure are higher, the assembly is more convenient, and the service life is longer. Further, in one example, the storage box 20, the pump housing 11 and the drive housing 1184 are integrally formed.

[0133] The washing device 1000 according to the embodiment of the present invention comprises: the placing component 100 according to the above embodiment of the present invention. The washing device 1000 may be a washing machine, a dishwasher, a sink or the like.

The washing tank 400 is located below the outlet of the mixing chamber 300. The detergent and the water flow can be mixed in the mixing chamber 300 and then flow to the washing tank 400 for washing clothes. It can be understood that when the water flow flows through the detergent in the mixing chamber 300, the purpose of dilution and mixing can be achieved, which is more conducive to washing. Of course, the present invention is not limited to this, and the delivery assembly 100 can also directly deliver the detergent into the washing tank 400.

[0135] According to the washing device 1000 of the embodiment of the present invention, by setting the dispensing component 100 according to the above-mentioned embodiment of the present invention, it is beneficial to avoid the dispensing pump 1 from reversely sucking in the detergent through the liquid outlet 112, and the accuracy of the detergent dispensing can be improved. At the same time, by reasonably setting the transmission ratio of the transmission mechanism 22 to control the movement stroke of the pump body 12, it is beneficial to increase the single dispensing amount of the dispensing device 10, reduce the number of dispensing times, and improve the overall performance of the washing device 1000.

[0145] Specifically, refer to Fig. 9 As shown, the mounting hole 2123 includes a first hole section 2124 and a second hole section 2125 that are connected to each other, the cross-sectional area of ​​the first hole section 2124 is larger than the cross-sectional area of ​​the second hole section 2125, the guide member 3 includes an abutment portion 31, a stop portion 32 and a guide portion 33 that are connected in sequence, the cross-sectional area of ​​the stop portion 32 is larger than the cross-sectional area of ​​the guide portion 33, and an elastic retaining member 34 is provided between the stop portion 32 and a side wall of the first hole section 2124 close to the second hole section 2125, the elastic retaining member 34 has an elastic force on the stop portion 32 so that the abutment portion 31 contacts the bottom wall surface of the guide groove 113.

[0146] Reference Figure 7As shown, a limiting protrusion 114 is also formed on the bottom wall surface of the second guide section 1132, and the limiting protrusion 114 is located between the first guide section 1131 and the second guide section 1132. Both ends of the limiting protrusion 114 are spaced apart from the side walls of the guide groove 113 and respectively define a first connecting gap 115 and a second connecting gap 116 connecting the first guide section 1131 and the second guide section 1132.

[0147] Reference Figure 4 and Figure 7 As shown, in the depth direction of the guide groove 113, a portion of the bottom wall surface of the second guide segment 1132 adjacent to the first position is higher than a portion of the bottom wall surface of the first guide segment 1131 adjacent to the first position, the first guide segment 1131 and the second guide segment 1132 form a first step surface 1136 adjacent to the first position, a portion of the bottom wall surface of the first guide segment 1131 adjacent to the second position is higher than a portion of the bottom wall surface of the second guide segment 1132 adjacent to the second position, the first guide segment 1131 and the second guide segment 1132 form a second step surface 1137 adjacent to the second position, and the guide member 3 is movably arranged on the driving mechanism 21 along the depth direction of the guide groove 113.

[0148] Reference Figure 5 , Figure 6 and Figure 7 As shown, at least a portion of the bottom wall surface of the second guide section 1132 adjacent to the first position constitutes a first transition surface 1138, the first transition surface 1138 is connected to the first step surface 1136, and the first transition surface 1138 gradually increases in the direction from the second position to the first position. At least a portion of the bottom wall surface of the first guide section 1131 adjacent to the second position constitutes a second transition surface 1139, the second transition surface 1139 is connected to the second step surface 1137, and the second transition surface 1139 gradually increases in the direction from the first position to the second position.

[0149] Further, refer to Figure 3 As shown, a guide hole 2111 extending in an arc shape is formed on the first driving member 211, and a guide column 2122 cooperating with the guide hole 2111 is formed on the second driving member 212. When the second driving member 212 rotates relative to the first driving member 211, the guide column 2122 moves along the extension direction of the guide hole 2111.

[0150] The transmission mechanism 22 is connected between the second driving member 212 and the sub-pump body 121 located on the rear side. The first driving member 211 is movable between a first position and a second position. The transmission mechanism 22 includes a first transmission member 221 and a second transmission member 222 that can be connected in a transmission manner. The first transmission member 221 is connected to the second driving member 212 and is a rack extending in the direction from the first position to the second position. The second transmission member 222 is a gear and is connected to the sub-pump body 121 located on the rear side. During the movement of the first driving member 211 from the first position to the second position, the first transmission member 221 and the second transmission member 222 are transmission-connected. During the movement of the first driving member 211 from the second position to the first position, the first transmission member 221 and the second transmission member 222 are separated.

[0151] Specifically, when the user drives the first driving member 211 to move from the first position to the second position, at the first position, since in the depth direction of the guide groove 113, the portion of the bottom wall surface of the second guide segment 1132 adjacent to the first position is higher than the portion of the bottom wall surface of the first guide segment 1131 adjacent to the first position, the first step surface 1136 will restrict the guide member 3 from moving toward the second guide segment 1132, and the guide member 3 can only move along the extension direction of the first guide segment 1131 (refer to Figure 4 113, and the second driving member 212 is moved along the path of a to b in the drawing. At this time, the motion trajectory of the second driving member 212 is a straight line. The first transmission member 221 drives the second transmission member 222 to rotate, and the second transmission member 222 drives the corresponding sub-pump body 121 to rotate, which can generate negative pressure in the liquid suction area 1111 and positive pressure in the liquid discharge area 1112. The lotion at the liquid inlet 111 flows to the liquid discharge area 1112 under the action of the pressure difference, and is discharged into the guide cavity 1185 through the liquid outlet 112, and finally flows into the mixing chamber 300 through the discharge port 1186 to achieve the delivery of the lotion. When the guide member 3 moves to the second step surface 1137, since in the depth direction of the guide groove 113, the bottom wall of the first guide section 1131 adjacent to the second position is higher than the bottom wall of the second guide section 1132 adjacent to the second position, the guide member 3 will "fall into" the second position. At the same time, in this process, the first elastic reset mechanism 2231 is compressed.

[0152] When the user's driving force F is canceled, the first driving member 211 moves from the second position to the first position under the drive of the first elastic reset mechanism 2231. At the second position, the second step surface 1137 restricts the guide member 3 from returning along the first guide segment 1131, and the guide member 3 can only return along the extension direction of the second guide segment 1132 (refer to Figure 4The guide member 3 moves toward the first position (the path b→c→d→a in the figure), so that the driving mechanism 21 can move along the second path. At this time, the guide member 3 drives the second driving member 212 to rotate, and the movement trajectory of the second driving member 212 is an arc. The first transmission member 221 and the second transmission member 222 are separated, and the dispensing device 10 does not dispense lotion, thereby achieving the purpose of unidirectional driving. When the guide member 3 passes through the second step surface 1137, the guide member 3 will "fall into" the first position.

[0153] It is understandable that, referring to Figure 8 As shown, the liquid suction area 1111 and the liquid discharge area 1112 of the delivery pump 1 used in the embodiment of the present invention are located in different areas. When the delivery device 10 is working normally, the user drives the first driving member 211 to move from the first position to the second position to achieve delivery. The liquid suction at the liquid inlet 111 and the liquid discharge at the liquid outlet 112 of the delivery pump 1 are completed synchronously in time, so no large restoring force is required, and only a small force is required to complete the delivery, which can greatly improve the comfort of user operation. At the same time, the transmission ratio of the first transmission member 221 and the second transmission member 222 is fixed and the moving distance of the driving member is fixed, so that the number of rotations of the corresponding sub-pump body 121 can be fixed, and the single delivery amount of the delivery device 10 can be fixed. The user can obtain the accurate total delivery amount by controlling the number of delivery times. On the basis of a certain volume of the delivery device 10, the single delivery amount of the delivery device 10 in the embodiment of the present invention is large, which is conducive to reducing the number of user delivery operations and further improving the user experience.

[0154] When the user's driving force is canceled, under the reset action of the first elastic reset member 223 and the constraint of the guide groove 113, the guide frame moves along the extension direction of the second guide section 1132 (refer to Figure 4 The path b→c→d→a in the middle) automatically returns from the second position to the first position, which is beneficial to ensure that the first transmission member 221 and the second transmission member 222 are separated, thereby achieving the purpose of one-way driving, and is beneficial to preventing the delivery pump 1 from reversely sucking in lotion through the liquid outlet 112, while avoiding the influence of the resistance of the pump body 12 when the driving mechanism 21 is reset, which can reduce the restoring force of the first elastic restoring member 223, and is beneficial to speed up the corresponding recovery speed, which is beneficial to improving the user experience.
