For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0049] The present invention will be further described in detail below with reference to the embodiments.

[0050] Example 1

[0051] like Figures 1 to 5 As shown, this embodiment provides a liquid storage box 1, which has a sealed chamber for storing additives. In this embodiment, the chamber inside the liquid storage box 1 is an independently sealed liquid storage chamber. The liquid storage box 1 also has a conductive detection unit that can detect the liquid level information of the additives inside. The conductive detection unit is an integral part of the liquid storage box 1. The liquid storage box 1 provided in this embodiment has higher integrity, independent usability, and reliability compared to the liquid storage boxes in the prior art.

[0052] The liquid storage box 1 provided in this embodiment has a conductive detection part that can detect the internal additive liquid level information, which solves the problems of complex assembly between the existing liquid storage box 1 and the conductive probe 2, poor sealing that easily leads to additive leakage, and the liquid storage box 1 being unusable after the conductive probe 2 is removed.

[0053] In one embodiment, the conductive detection unit and the liquid storage box 1 are an integral structure. The conductive detection unit is integrally formed within the liquid storage box 1 using a specific processing technology. By making the conductive detection unit and the liquid storage box 1 an integral structure, no further assembly or installation is required, simplifying the assembly process. Furthermore, since the conductive detection unit and the liquid storage box 1 are an integral structure, there is no issue of additive leakage due to poor sealing, ensuring the reliability of the liquid storage box 1.

[0054] Alternatively, in another solution, the conductive detection part is part of the structure of the liquid storage box 1, and the box body part of the liquid storage box 1 is made of a metal conductive material to form the conductive detection part. By making the box body part of the liquid storage box 1 of a metal conductive material to form the conductive detection part, the conductive detection part is part of the structure of the liquid storage box 1, improving the integrity of the liquid storage box 1.

[0055] Further, the conductive detection part is at least two conductive probes 2 integrally formed in the liquid storage box 1. In this embodiment, the conductive detection part is taken as two conductive probes 2 for detailed description. Of course, the conductive detection part can also be three conductive probes 2, four conductive probes 2, etc.

[0056] One end of the conductive probe 2 is a liquid level detection end 21 that extends into the additive inside the liquid storage box 1 for detecting the liquid level. The liquid level detection end 21 can detect the additive liquid level information. The other end of the conductive probe 2 has a conductive contact patch 22 that is in contact and electrically connected with an external circuit. When the liquid storage box 1 is placed into the delivery device 4, the conductive contact patch 22 can be connected with the external circuit.

[0057] The lower end of the conductive probe 2 is the liquid level detection end 21. The upper end of the conductive probe 2 is provided with a conductive contact patch 22 with an increased outer diameter. The conductive contact patch 22 is exposed outside the liquid storage box 1, so that when the liquid storage box 1 is placed into the delivery device 4, it can be connected with the detection circuit, thereby achieving the purpose of detecting the additive liquid level information in the liquid storage box 1.

[0058] In one solution, as shown in Figures 3 to 5 The conductive contact patch 22 protrudes from the outer wall surface of the liquid storage box 1. The conductive contact patch 22 can be provided in a square shape or a strip structure with a certain thickness. The conductive contact patch 22 can protrude from the outer wall surface of the liquid storage box 1, or the conductive contact patch 22 can be partially embedded in the liquid storage box 1 and partially protrude from the liquid storage box 1.

[0059] Alternatively, in another solution, the conductive contact patch 22 is embedded in the box body of the liquid storage box 1, and the top wall of the conductive contact patch 22 is flush with the outer wall surface of the liquid storage box 1. The above design makes the overall appearance of the liquid storage box 1 better, and the outer side looks flat and integrated.

[0060] Further, the two conductive probes 2 are spaced apart, and the liquid level detection end 21 of the conductive probe 2 extends into the bottom of the liquid storage box 1 and is higher than the bottom wall 11 of the liquid storage box 1. The distance between the liquid level detection end 21 of the conductive probe 2 and the bottom wall 11 of the liquid storage box 1 can be adjusted according to the actual liquid level detection requirements. The higher the detected liquid level, the greater the distance between the liquid level detection end 21 of the conductive probe 2 and the bottom wall 11 of the liquid storage box 1.

[0061] In an embodiment, a plurality of groups of conductive probes 2 can be arranged in the liquid storage box 1, and the different groups of conductive probes 2 are arranged at different distances from the bottom wall 11 of the liquid storage box 1 to detect different liquid levels in the liquid storage box 1.

[0062] For example, the overall height of the liquid storage box 1 is set as L, and three groups of conductive probes 2 are arranged in the liquid storage box 1, wherein the distance from the first group of conductive probes 2 to the bottom wall 11 of the liquid storage box 1 is 1 / a L, the distance from the second group of conductive probes 2 to the bottom wall 11 of the liquid storage box 1 is 1 / b L, and the distance from the third group of conductive probes 2 to the bottom wall 11 of the liquid storage box 1 is 1 / c L, wherein a, b, and c are integers greater than 1, a > b > c, and the values of a, b, and c can be set according to the detection needs.

[0063] When the liquid storage box 1 is placed in the delivery device 4, when the liquid level in the liquid storage box 1 drops below 1 / a L, the circuit between the two liquid level detection ends 21 detected by the first group of conductive probes 2 is disconnected, and the detection circuit corresponding to the first group of conductive probes 2 cannot detect current or the current becomes very weak, and the control unit of the delivery device 4 feeds back a signal, and the control unit sends a prompt signal to the user that the liquid level of the additive in the liquid storage box 1 has dropped to 1 / a L.

[0064] Similarly, when the liquid level in the liquid storage box 1 drops below 1 / b L, the detection circuit corresponding to the second group of conductive probes 2 cannot detect current or the current becomes very weak, and the control unit sends a prompt signal to the user that the liquid level of the additive in the liquid storage box 1 has dropped to 1 / b L.

[0065] When the liquid level in the liquid storage box 1 drops below 1 / c L, the detection circuit corresponding to the third group of conductive probes 2 cannot detect current or the current becomes very weak, and the control unit sends a prompt signal to the user that the liquid level of the additive in the liquid storage box 1 has dropped to 1 / c L, and the control unit sends an alarm signal to the user, prompting the user to replace the liquid storage box 1 in time because the additive in the liquid storage box 1 is insufficient.

[0066] Through the above scheme, the user can be prompted in stages according to the drop of the liquid level in the liquid storage box 1, so that the user has more time to prepare, and the user experience is better.

[0067] Preferably, the delivery device 4 is further provided with a display module, and the control unit feeds back the liquid level information of the additive in the liquid storage box 1 detected by the first group of conductive probes 2, the second group of conductive probes 2, and the third group of conductive probes 2 to the display module for display, providing a more intuitive reference for the user.

[0068] Furthermore, the liquid storage box 1 is provided with a liquid outlet, and a liquid guiding interface structure 3 for guiding the additive in the liquid storage box 1 to the dispensing unit is installed at the liquid outlet. The liquid guiding interface structure 3 has a liquid guiding channel with an inlet end 31 communicating with a sealed chamber inside the liquid storage box 1. The liquid level detection end 21 of the conductive probe 2 is not lower than the inlet end 31 of the liquid guiding interface structure 3. The inlet end 31 of the liquid guiding interface structure 3 extends downward to the bottom wall 11 of the liquid storage box 1 to ensure that the additive in the liquid storage box 1 can be completely drawn out.

[0069] The outlet end of the liquid guiding interface structure 3 is connected to the dispensing unit of the dispensing device 4. By setting the liquid level detection end 21 of the conductive probe 2 at a height not lower than the inlet end 31 of the liquid guiding interface structure 3, a prompt message is sent to the user when the liquid level in the storage box 1 drops to the position of the inlet end 31 of the liquid guiding interface structure 3, effectively avoiding the phenomenon that the dispensing unit cannot draw the additive in the storage box 1.

[0070] Furthermore, the conductive probe 2 and the liquid storage box 1 are an integral structure formed by melting and / or hot pressing and / or hot riveting and / or bonding processes. Of course, the conductive probe 2 and the liquid storage box 1 are not limited to being integrally formed using the above processes.

[0071] like Figure 4 and Figure 5 As shown, the conductive probe 2 can be embedded or attached to the inner wall of the liquid storage box 1, or the conductive probe 2 can be embedded in the middle position of the liquid storage box 1. The conductive probe 2 is part of the liquid storage box 1, which ensures the integrity of the liquid storage box 1.

[0072] Furthermore, in another embodiment, the conductive probe 2 is part of the structure of the liquid storage box 1. The liquid storage box 1 includes a bottom wall 11 and a top wall 12, and a peripheral side wall 13 connected between the top wall 12 and the bottom wall 11. The peripheral side wall 13 is made of a metal conductive material to form the conductive detection part. The conductive detection part consists of two long strip-shaped conductive probes 2 that extend from the top wall 12 of the liquid storage box 1 to the bottom of the liquid storage box 1 and are adapted to the shape of the liquid storage box 1.

[0073] Preferably, the outer wall surface of the conductive probe 2 is flush with the outer wall surface of the liquid storage box 1, the inner wall surface protrudes from the inner wall surface of the liquid storage box 1, the upper end surface of the conductive probe 2 protrudes from the top wall 12 of the liquid storage box 1 or can be flush with the top wall 12 of the liquid storage box 1, and the lower end of the conductive probe 2 extends to a position close to the bottom wall 11 of the liquid storage box 1.

[0074] Further, two of the conductive probes 2 are arranged on the same side wall of the liquid storage box 1, i.e. two parts of the same side wall of the liquid storage box 1 are made of metal conductive material to form the conductive probes 2.

[0075] Alternatively, in another solution, two of the conductive probes 2 are arranged on two adjacent side walls of the liquid storage box 1, i.e. two parts of the two adjacent side walls of the liquid storage box 1 are made of metal conductive material to form the conductive probes 2.

[0076] Alternatively, in another solution, two of the conductive probes 2 are arranged on two opposite side walls of the liquid storage box 1, i.e. two parts of the two opposite side walls of the liquid storage box 1 are made of metal conductive material to form the conductive probes 2.

[0077] The liquid storage box 1 provided by the embodiment has the function of detecting the internal additive liquid level information, and the conductive detection part is integrally formed on the liquid storage box 1, or the box body of the liquid storage box 1 is made of conductive material to form the conductive detection part, so that the conductive detection part and the liquid storage box 1 are in an integrated structure, which solves the problems of complex assembly between the existing liquid storage box 1 and the conductive probe 2, poor sealing, additive leakage, and the liquid storage box 1 cannot be used after the conductive probe 2 is taken out.

[0078] As shown in Figures 1 to 5 The embodiment also provides a delivery device 4 with the liquid storage box 1, and the delivery device 4 is provided with a liquid level detection module, the liquid level detection module is provided with two conductive contact terminals 42 corresponding to the conductive contact pieces 22 of the two conductive probes 2, when the liquid storage box 1 is placed in the delivery device 4, the conductive contact terminals 42 of the liquid level detection module are in contact with the conductive contact pieces 22 of the conductive detection part, and the feedback signal output by the liquid level detection module is used to judge the liquid level information of the additive in the liquid storage box 1.

[0079] Further, as shown in Figures 1 to 3 The delivery device 4 is provided with a containing part for placing the liquid storage box 1, and the liquid level detection module is provided with two conductive contact terminals 42 corresponding to the conductive contact pieces 22 of the two conductive probes 2.

[0080] Through the above setting, after the liquid storage box 1 is respectively loaded into the containing part of the dosing device 4, the conductive contact piece 221 installed on each liquid storage box 1 can be in contact with the conductive contact terminal 42. The liquid level detection module has a detection circuit. The detection circuit can be any existing circuit structure, but it needs to ensure that it has two ends, the two ends are respectively connected to different conductive contact terminals 42, and a circuit structure that can emit a high-level signal when the conductive contact terminals 42 connected at both ends are conducted to form a loop through the additive in the liquid storage box 1, and emit a low-level signal when the conductive contact terminals 42 connected at both ends are disconnected, so as to realize that the detection circuit can emit different signals when it is conducted to form a loop and disconnected and cannot form a loop.

[0081] When the liquid storage box 1 is placed in the containing part, the conductive contact piece 22 of the two conductive probes 2 is respectively in contact with the conductive contact terminal 42, and the liquid level detection module is conducted. When the liquid storage box 1 is taken out of the containing part, it is separated from the conductive contact terminal 42, and the detection circuit between the liquid level detection module and the conductive probe 2 is disconnected.

[0082] When the additive liquid level in the liquid storage box 1 is higher than the liquid level detection end 21 of the lower end of the conductive probe 2, the two conductive probes 2 conduct the detection circuit between them and the liquid level detection module. The liquid level detection module can output a high-level signal, and it is detected that there is enough additive in the liquid storage box 1. Conversely, if the additive liquid level in the liquid storage box 1 is lower than the liquid level detection end 21 of the lower end of the conductive probe 2, the circuit between the two conductive probes 2 is disconnected, and the liquid level detection module can output a low-level signal. It is inferred that the liquid level of the additive in the liquid storage box 1 is lower than the set value, prompting the user to replace the liquid storage box 1 in time.

[0083] Further, in the embodiment, the dosing device 4 is arranged on the water inlet pipeline connected between the clothes treatment equipment and the tap water joint. The dosing device 4 includes an upper cover 41 located above the containing part. The conductive contact terminal 42 can be arranged on the upper cover 41.

[0084] The end of the conductive contact terminal 42 is provided with a spring contact piece. When the user loads the liquid storage box 1 into the containing part of the dosing device 4, the spring contact piece of the conductive contact terminal 42 arranged in the upper cover 41 will contact the liquid level detection end 21 of the conductive probe 2 on the liquid storage box, thereby realizing liquid level detection.

[0085] In the embodiment, as shown in Figure 1 and Figure 2 The conductive contact terminal 42 is fixedly arranged on the upper cover 41 located at the top of the liquid storage box 1. The upper cover 41 is integrated with a waterway. Of course, the conductive contact terminal 42 can also be arranged at other positions of the dosing device 4, as long as the conductive contact piece 22 of the liquid storage box 1 can be in close contact with the conductive contact terminal 42 when the liquid storage box 1 is placed in the containing part.

[0086] This embodiment also provides a clothing processing device, wherein the inlet pipe between the clothing processing device and the tap water connector is equipped with the aforementioned dispensing device. The dispensing device 4 provided in this embodiment is an external dispensing device 4, and the dispensing device 4 and the clothing processing device each have independent control systems. The dispensing device 4 is installed on the inlet pipe between the tap water connector and the inlet valve of the clothing processing device. The clothing processing device is a washing machine or a washer-dryer combo.

[0087] The dispensing device 4 includes a liquid storage module connected to the garment processing equipment via a dispensing pipeline, and a dispensing unit installed on the dispensing pipeline for dispensing additives to the garment processing equipment. The liquid storage module contains the aforementioned liquid storage box 1. The dispensing device 4 is installed on an inlet pipeline connecting a tap water connector and the inlet valve of the garment processing equipment. The two ends of the dispensing pipeline are respectively connected to the liquid storage box 1 and the inlet pipeline. The dispensing unit is installed on the dispensing pipeline, and the dispensing unit includes a dispensing pump or a venturi tube for dispensing additives into the inlet pipeline.

[0088] When water enters the garment processing equipment, the inlet valve of the garment processing equipment is opened, and the water from the tap water connector passes through the inlet pipe. The dispensing unit dispenses the additive from the storage box 1 into the inlet pipe, so that the additive enters the garment processing equipment along with the tap water in the inlet pipe.

[0089] In this embodiment, the dispensing device 4 can be installed outside the clothing processing equipment, that is, the dispensing device 4 is installed on the clothing processing equipment and located outside the clothing processing equipment. For example, the dispensing device 4 can be fixedly installed on the outer wall of the housing of the clothing processing equipment.

[0090] Alternatively, the dispensing device 4 and the clothing processing equipment can be two independent sets of equipment, with no assembly or connection between them. In this case, the location of the dispensing device 4 is relatively unrestricted, as long as the dispensing device 4 can be connected to the water inlet pipe between the washing machine and the tap water connector, the additive can be added to the washing machine along with the water entering through the water inlet pipe.

[0091] Example 2

[0092] like Figures 6 to 13 As shown, this embodiment introduces a liquid storage box based on embodiment one. The liquid storage box 1 has a sealed chamber for storing additives. At least two conductive contacts 22 are provided on the outer wall of the liquid storage box 1 to contact the additives in the sealed chamber. The combination of the number and position of the conductive contacts 22 on the liquid storage box corresponds to the type of additives stored in the liquid storage box 1.

[0093] In the present application, by setting a plurality of conductive pads 22 exposed on the outer wall of the liquid storage box 1, the type of additive contained in the liquid storage box 1 is accurately identified by using any one or a combination of the number, relative position, and setting position information of the conductive pads 22 on the liquid storage box 1, thereby achieving a significant technical progress in clearly identifying the additive category information of different liquid storage boxes 1.

[0094] As shown in Figure 5 and Figure 10 , Figure 11 , the present embodiment introduces a liquid storage box, which has a sealed chamber for storing additives in the liquid storage box 1, and a first conductive pad 221 and a first conductive pad 222 are arranged on the outer wall of the liquid storage box 1 with a certain distance, and the distance between the first conductive pad 221 and the first conductive pad 222 corresponds to the type of additive stored in the liquid storage box 1.

[0095] In the present embodiment, there are a plurality of liquid storage boxes 1, and each liquid storage box 1 corresponds to contain different types of additives, such as detergents, fragrance enhancers, softeners, disinfectants, etc., so that different types of additives can be added separately or in combination, and the corresponding processing of clothes can be realized when the clothes processing device executes different types of programs using different types of additives. At the same time, in the embodiment of the present application, different concentrations of detergents, such as super-concentrated, concentrated, ordinary, low-foaming, etc., can also be stored in each liquid storage box 1 of the additive dispensing device 4, so that the corresponding type of detergent can be added when the clothes processing device executes different washing programs, so as to realize the corresponding washing of different clothes, and further achieve the purpose of improving the washing effect of the clothes processing device.

[0096] In the present embodiment, the distance includes the distance information, the relative spatial orientation information, and the position information of the first conductive pad 221 and the first conductive pad 222 arranged on the liquid storage box 1.

[0097] For example, as shown in Figure 10 , the distance between the first conductive pad 221 and the first conductive pad 222 arranged on the detergent storage box 1 for storing detergents is 1 cm, and the distance between the first conductive pad 221 and the first conductive pad 222 arranged on the rinse agent storage box 1 for storing rinse agents is 2 cm.

The liquid outlet is provided at one end of the square column-shaped storage box 1. In order to realize the sealing of the storage box 1, the container connecting part is generally installed at the liquid outlet in the embodiment.

The valve body is in abutment with one end of the sleeve structure facing the containing part under the elastic force of the spring, and correspondingly closes the passage formed in the sleeve structure, so that the liquid outlet of the storage box is closed and the storage box forms a closed container. At the same time, when the storage box is loaded into the containing part of the additive feeding device, the liquid guide connecting part contacts the valve body and drives the valve body to move to the inside of the storage box against the elastic force of the spring, so as to open the liquid outlet of the storage box and realize the effect of feeding the additive.

[0103] At the same time, in order to enable the different storage boxes 1 to be extracted after installation, the following settings are made in the embodiment:

[0104] In this embodiment, the distance between the first conductive contact 221 of the liquid storage box for storing different kinds of additives and the liquid outlet of the liquid storage box 1 is the same, so as to ensure that the relative positions of each conductive contact 22 of the liquid storage box 1 after being installed correspondingly on the additive feeding device 4 remain constant, and then the additive feeding device 4 can accurately extract the additive according to the information of the kind of additive provided by the conductive contact 22 arranged on the liquid storage box 1. Further preferably, in order to further ensure the accuracy of extraction, the liquid storage boxes 1 for storing different kinds of additives have the same shape. Still further preferably, the liquid storage box 1 is provided with a location correcting structure for keeping the installation position unique, and the location correcting structure can be arranged by using the shape of the liquid storage box 1 itself, the concave-convex structure arranged on the outer surface of the liquid storage box 1, etc. (not shown in the figure).

[0105] Embodiment Three

[0106] The embodiment is based on the above-mentioned embodiments one and two and further has the following technical features:

[0108] In this embodiment, the number information of the conductive contacts 22 is the number of the conductive contacts 22 arranged on the outer surface of the liquid storage box 1; for example:

[0117] As shown in Figure 8 and Figure 9 In the embodiment, the conductive probe 2 is arranged on the storage box 1 and extends into the sealed chamber, the conductive contact 22 exposed on the outer wall of the storage box 1 is connected with the conductive probe 2, and the conductive contact 22 is in conduction with the additive stored in the sealed chamber through the conductive probe 2.

[0118] In the embodiment, the conductive probe 2 is installed on the storage box 1, and one end of the conductive probe 2 is connected with the storage box 1 and the other end extends into the sealed chamber.

[0119] In the embodiment, the conductive probe 2 can be integrally arranged with the conductive contact 22: one end of the conductive probe 2 directly constitutes the conductive contact 22; or the conductive probe 2 is arranged in connection with the conductive contact 22: the contact piece arranged independently on the storage box 1 and in contact with the conductive probe 2 constitutes the conductive contact 22.

[0120] In the embodiment, in order to realize the convenient assembly of the storage box, the storage box 1 with the conductive contact 22 mark can be set to have a unique shape, so that the storage boxes 1 for storing different kinds of additives have the same shape, so as to improve the replacement convenience of the storage box 1.

[0121] As shown in Figures 14 to 17As shown, in this embodiment, the liquid storage box 1 has a top wall 12 and a bottom wall 11 on its two sides in the vertical direction, and the other sides of the liquid storage box 1 are all peripheral sidewalls 13.

[0122] like Figure 14 As shown, in this embodiment, when the liquid storage box 1 is placed horizontally, each conductive contact 22 on the liquid storage box 1 is located on the top wall 12 of the liquid storage box 1, and each conductive probe 2 extends vertically downward from the top wall 12 of the liquid storage box 1. By utilizing the conductive probe 2 with vertical extension height, the conductivity of the circuit formed between the conductive probes 2 can be detected when the additive liquid level in the liquid storage box 1 changes, thereby achieving the effect of detecting the additive liquid level in the liquid storage box 1.

[0123] Meanwhile, in this embodiment, when the liquid storage box 1 is placed horizontally, each conductive contact 22 on the liquid storage box 1 is located on the bottom wall 11 of the liquid storage box 1, and each conductive probe 2 extends vertically upward from the bottom wall 11 of the liquid storage box 1. By using the conductive probe 2 with vertical extension height, the conductivity of the circuit formed between the conductive probes 2 can be detected when the additive liquid level in the liquid storage box 1 changes, thereby achieving the effect of detecting the additive liquid level in the liquid storage box 1 (not shown in the figure).

[0124] like Figure 15 As shown, in this embodiment, when the liquid storage box 1 is placed horizontally, each conductive contact 22 on the liquid storage box 1 is located on the peripheral wall side of the liquid storage box 1. Each conductive probe 2 includes a horizontal section 202 and a vertical section 201 vertically connected to one end of the horizontal section 202. One end of the horizontal section 202 is exposed on the peripheral wall 13 of the liquid storage box 1 to directly form a conductive contact 22 or is connected to the conductive contact 22 provided on the liquid storage box 1. The other end is located inside the liquid storage box 1 and connected to the upper end of the vertical section 201. The other end of the vertical section 201 extends downward to above the bottom wall 11 of the liquid storage box 1 to contact the additive in the sealed cavity 7 of the liquid storage box 1. Similarly, the conductivity of the circuit formed between the conductive probes 2 can be detected when the liquid level of the additive in the liquid storage box 1 changes, thereby achieving the effect of detecting the liquid level of the additive in the liquid storage box 1. Of course, in this embodiment, the other end of the horizontal segment 202 can also be connected to the lower end of the vertical segment 201 and extend upwards to below the top wall 12, thus achieving the same inventive purpose. In this embodiment, the horizontal segment 202 and the liquid storage box 1 are formed into an integral structure through melting and / or hot pressing and / or hot riveting and / or bonding processes to achieve fixed installation of the conductive probe 2 and the liquid storage box 1. In this embodiment, the lower end of the vertical segment 201 is lower than or equal to the minimum liquid level height of the liquid storage box 1, and the upper end is higher than or equal to the maximum liquid level height of the liquid storage box 1.

[0125] In this embodiment, the liquid storage box 1 can also be placed vertically:

[0126] As shown in Figure 16 each of the conductive tabs 22 on the liquid storage box 1 is located on the bottom wall 11 of the liquid storage box 1, and each of the conductive probes 2 vertically extends upward from the bottom wall 11 of the liquid storage box 1, so that the conductive probes 2 with the upward and downward extending height can detect the conductivity formed between the conductive probes 2 when the additive liquid level in the liquid storage box 1 changes, thereby achieving the effect of detecting the additive liquid level in the liquid storage box 1. The upward extending height of the conductive probes 2 in the liquid storage box 1 needs to be greater than or equal to the empty liquid level of the liquid storage box 1, so as to effectively detect the identity of the liquid storage box 1. Of course, in order to ensure the accuracy of the liquid level detection in the liquid storage box 1, it is most optimal to set the height of the conductive probes 2 to the maximum liquid level of the liquid storage box 1.

[0127] As shown in Figure 12 each of the conductive tabs 22 on the liquid storage box 1 is located on the bottom wall 11 of the liquid storage box 1, and each of the conductive probes 2 vertically extends upward from the bottom wall 11 of the liquid storage box 1, so that the conductive probes 2 with the upward and downward extending height can detect the conductivity formed between the conductive probes 2 when the additive liquid level in the liquid storage box 1 changes, thereby achieving the effect of detecting the additive liquid level in the liquid storage box 1. The upward extending height of the conductive probes 2 in the liquid storage box 1 needs to be greater than or equal to the empty liquid level of the liquid storage box 1, so as to effectively detect the identity of the liquid storage box 1. Of course, in order to ensure the accuracy of the liquid level detection in the liquid storage box 1, it is most optimal to set the height of the conductive probes 2 to the maximum liquid level of the liquid storage box 1.

In order to ensure that the liquid storage box 1 is installed in the accommodating part according to the fixed relative position, so as to realize the contact between the conductive contact piece 22 of the liquid storage box 1 and the conductive contact terminal 42, and then enable different liquid storage boxes 1 to extract unique information according to the conductive contact piece 22 and the conductive contact terminal 42 in conduction after installation, the following settings need to be made on the liquid storage box 1 and / or the accommodating part:

[0141] In the embodiment, the spacing between the first conductive contact 221 of the liquid storage box 1 for storing different kinds of additives and the liquid outlet of the liquid storage box 1 is the same, so as to ensure that the relative positions of the conductive contacts 22 of the liquid storage box 1 after being installed correspondingly remain constant on the additive dispensing device 1, and then the additive dispensing device 4 can accurately extract the additive according to the information of the kind of the additive extracted by the conductive contact 22 arranged on the liquid storage box. Further preferably, in order to further ensure the extraction accuracy, the liquid storage boxes 1 for storing different kinds of additives have the same shape. Still further preferably, the liquid storage box 1 is provided with a location correction structure for keeping the installation position unique, and the location correction structure can be arranged by using the shape of the liquid storage box 1 itself, the concave-convex structure arranged on the outer surface, etc., so that the liquid storage box 1 can only be assembled in the unique position form in the accommodating part of the additive dispensing device 4 under the action of the location correction structure.

For example, the feeding device can be fixedly installed on the outer side wall of the shell of the laundry treating device. For example, the additive feeding device is connected to the water inlet pipe of the laundry treating device, and the additive is fed into the water inlet pipe, and the additive is fed into the barrel of the laundry treating device together with the water of the laundry treating device.
