The delivery system 10 provided in this embodiment of the disclosure includes a delivery unit 100 and a delivery pipeline 500, where the delivery unit 100 includes a box body 110, the box body 110 includes a liquid storage box 111 and a box cover 112, the liquid storage box 111 is formed with a liquid storage cavity 1101, so as to provide a housing space for a fluid or a fluid container 10 'in practical application, and the box cover 112 is detachably disposed on the liquid storage box 111, so that by removing the box cover 112 from the liquid storage box 111, the covered area of the liquid storage cavity 1101 can be reduced, the space openness and the structural trafficability of the liquid storage cavity 1101 are improved, and thus the fluid or the fluid container 10' can be conveniently placed into the liquid storage cavity 1101 in practical application. The input end of the delivery pipeline 500 is located in the liquid storage cavity 1101, so that in the case that the liquid storage cavity 1101 contains the fluid, the input end of the delivery pipeline 500 can directly access the fluid in the liquid storage cavity 1101 and guide the fluid to flow outside the liquid storage cavity 1101; in the case that the fluid container 10' is provided in the liquid storage chamber 1101, the input end of the delivery pipe 500 is connected to the fluid container 10', so that the input end of the delivery pipe 500 can receive the fluid contained in the fluid container 10' and guide the fluid to flow outside the liquid storage chamber 1101.

The delivery system 10 provided in the embodiment of the present disclosure may be applied to a laundry treatment apparatus, such as a washing machine, a washing and drying integrated machine, etc., in practical applications; accordingly, the fluid may be, but not limited to, a detergent such as a laundry detergent, a softener, a detergent, a disinfectant, etc., and the fluid container 10' may be a detergent container suitable for machine washing such as an ink cartridge of an ink cartridge type detergent or a capsule of a capsule type detergent.

Taking the foregoing dispensing system 10 as an example when applied to a laundry treatment apparatus, the laundry treatment apparatus generally has a laundry treatment chamber, the foregoing liquid storage chamber 1101 or a fluid container 10' in the liquid storage chamber 1101 may be communicated with the foregoing laundry treatment chamber through the foregoing dispensing pipeline 500, that is, an output end of the dispensing pipeline 500 may be used to be communicated with the foregoing laundry treatment chamber, so that a cleaning agent in the liquid storage chamber 1101 may be output to the foregoing laundry treatment chamber through the dispensing pipeline 500, so as to participate in a laundry treatment process, thereby improving convenience of dispensing the cleaning agent in the laundry treatment process, and also being helpful for improving accuracy of dispensing the cleaning agent, reducing probability of pouring the cleaning agent, and improving cleanliness and sanitation of the laundry treatment process.

It will be appreciated that in practice, the delivery line 500 may be in direct or indirect communication with the laundry treatment chamber.

It will be appreciated that, as shown in fig. 2, in the case where the fluid container 10 'needs to be placed in the fluid storage chamber 1101, the box cover 112 may be removed first, and then the operation of placing the fluid container 10' and docking the delivery pipe 500 may be performed; it should be noted that, as shown in fig. 1 and fig. 2, in the case where the fluid container 10 'is disposed in the fluid chamber 1101, the lid 112 may be further mounted on the fluid container 111 to cover the fluid chamber 1101, or the lid 112 may not be further mounted to keep the fluid chamber 1101 open, and may be specifically configured in combination with the actual volume of the fluid container 10', for example, in the case where the volume of the fluid container 10 'is relatively large and the mounting position of the lid 112 is easily interfered, the lid 112 may not be further mounted to avoid structural damage, whereas in the case where the volume of the fluid container 10' is relatively small, the lid 112 may be further mounted to ensure the environmental stability inside the fluid chamber 1101 and the safety and reliability of the fluid delivery process.

It should be noted that, the detergent dispensing device of the laundry treatment apparatus in the conventional technology generally only has a liquid storage space for containing the liquid detergent, but the liquid storage space does not have an interface for docking with a detergent cartridge or a capsule, so that the dispensing device of this type can only receive the liquid detergent manually filled by a user, that is, the dispensing device of this type can only be suitable for pouring and filling the detergent; or the dispensing device is only provided with an interface for abutting the ink box or the capsule of the cleaning agent, but the area where the interface is positioned does not have the capacity of containing liquid, so that the dispensing device of the type can only fill the cleaning agent in a mode of replacing the ink box, namely the dispensing device of the type can only be suitable for replacing the cleaning agent used by the container; based on the foregoing, the clothes treatment device often can only adopt the filling mode of a cleaning agent, namely pouring filling or container replacement, so that the cleaning agent filling mode of the clothes treatment device is single, and a user sometimes has difficulty in filling according to the use mode of the cleaning agent, so that the use convenience of the throwing device is poor, and the improvement of the use experience of the product user is limited. The delivery system 10 provided by the disclosure is based on the foregoing arrangement, so that a user can conveniently take different filling modes according to the using modes of the cleaning agent, the use convenience of the delivery system 10 is further improved, the integration of the delivery system 10 is enhanced, the delivery system 10 can be applicable to different cleaning agent filling modes, meanwhile, the delivery system 10 has higher structural compactness, the volume or the quality of the clothes treatment equipment can be prevented from being greatly increased in practical application, and the miniaturization and the light weight level of the clothes treatment equipment are facilitated to be improved.

It will be appreciated that the foregoing delivery system 10 has good applicability to small laundry treatment apparatus; the small laundry treating apparatus generally refers to a laundry treating apparatus having a laundry treating capacity of 3kg or less.

As shown in fig. 4, 5, 7-9, in some examples, the delivery unit 100 further comprises: the lid 120, the lid 112 is formed with a dispensing opening 1102, and the lid 120 is movably disposed on the lid 112 for covering or opening the dispensing opening 1102.

As shown in fig. 1-3, 13-15, in some examples, the delivery system 10 further includes: the pumping unit 200 is connected to the output end of the delivery pipe 500.

In this technical solution, the delivery system 10 may further include a pumping unit 200 that is connected to the output end of the delivery pipeline 500, where in practical application, the pumping unit 200 is configured to pump fluid from the input end to the output end of the delivery pipeline 500, and in a case where the delivery system 10 is applied to a laundry treatment apparatus, the pumping unit 200 is configured to pump the fluid to the laundry treatment chamber, so that based on the foregoing setting, the fluid delivery efficiency of the delivery system 10 may be improved, and the requirement of the delivery system 10 on the setting position may be reduced, thereby improving the space utilization rate of the laundry treatment apparatus, and improving the miniaturization and light-weight level of the laundry treatment apparatus.

In some examples, the pumping unit 200 includes a peristaltic pump or a plunger pump.

In this technical solution, the pumping unit 200 may include a peristaltic pump, that is, the pumping unit 200 may pump the fluid in the liquid storage cavity 1101 by using the peristaltic pump, it may be understood that the peristaltic pump has good self-suction and sealing performance, so that the conveying capability of the pumping unit 200 to the high-viscosity fluid may be improved, the conveying of the cleaning agent by the pumping unit 200 may be facilitated, the risk of leakage of the pumping unit 200 may be reduced, and the cleaning performance and reliability of the pumping unit 200 may be improved.

Or the pumping unit 200 may include a plunger pump, that is, the pumping unit 200 may pump the fluid in the liquid storage cavity 1101 by using the plunger pump, it may be understood that the plunger pump has a higher output pressure and output efficiency, so that the detergent delivery performance of the pumping unit 200 may be improved, which is beneficial to improving the delivery efficiency of the delivery unit 100.

As shown in fig. 1-3 and 15, in some examples, the delivery system 10 further includes: the liquid amount detection unit 300 is used for detecting the liquid remaining amount in the liquid storage cavity 1101.

In this technical solution, the dispensing system 10 may further include a liquid amount detecting unit 300, where the liquid amount detecting unit 300 is used for detecting the liquid remaining amount in the liquid storage chamber 1101, so as to facilitate the user to understand the use condition of the cleaning agent during the use process, which is beneficial to further improving the convenience of use of the dispensing system 10.

It is understood that in the case where the fluid container 10 'is housed in the fluid chamber 1101, the liquid remaining in the fluid chamber 1101 refers to the liquid remaining in the fluid container 10'.

In some examples, the liquid amount detection unit 300 includes: a negative pressure sensor 320 for detecting the pressure in the delivery line 500.

In this technical solution, the liquid amount detecting unit 300 may include a negative pressure sensor 320, where the negative pressure sensor 320 is configured to detect a pressure in the delivery pipe 500, so as to determine a liquid remaining amount in the liquid storage chamber 1101 based on the detected pressure, and based on the foregoing arrangement, it is beneficial to avoid the liquid amount detecting unit 300 directly contacting the liquid in the liquid storage chamber 1101, accordingly, it is convenient to arrange the liquid amount detecting unit 300 at a portion of the delivery pipe 500 outside the liquid storage chamber 1101, so as to improve the openness of the installation position of the liquid amount detecting unit 300, improve the convenience during line connection, and correspondingly, also reduce the occupation of the liquid amount detecting unit 300 on the internal space of the liquid storage chamber 1101, and improve the effective volume of the liquid storage chamber 1101.

As shown in fig. 15, in some possible examples, the liquid amount detection unit 300 may include a magnetic levitation 310, the delivery unit 100 further includes a mounting column 160, the mounting column 160 is located in the liquid storage cavity 1101 and is disposed along the depth direction of the liquid storage cavity 1101, and the magnetic levitation 310 is movably sleeved on the mounting column 160, so that based on the foregoing arrangement, the moving range of the magnetic levitation 310 may be restricted, and the stable and smooth operation of the magnetic levitation 310 is ensured.

It can be understood that, in the case that the liquid level detection unit 300 includes the aforementioned magnetic levitation 310, the liquid level detection unit 300 is a magnetic levitation 310 type liquid level sensor, correspondingly, in the case that the liquid storage chamber 1101 has liquid therein, the magnetic levitation 310 floats on the liquid and rises and falls along with the change of the liquid level, and correspondingly, the magnetic levitation 310 type liquid level sensor may further include a magnetic switch or other means for sensing the position of the magnetic levitation 310, and a processing means for converting the position into liquid level information, so as to obtain the liquid level in the liquid storage chamber 1101.

As shown in fig. 15, in some possible examples, the bottom of the reservoir 1101 has a recessed area 1101a, and one end of the mounting post 160 is located within the recessed area 1101 a.

It can be appreciated that, since the magnetic levitation 310 can levitate in the liquid, if the amount of the liquid in the liquid storage chamber 1101 is small, and the magnetic levitation 310 is abutted against the bottom of the liquid storage chamber 1101, the liquid amount change of the remaining liquid is difficult to be detected by the liquid amount detecting unit 300, and the detection accuracy of the liquid amount detecting unit 300 is reduced. Based on the foregoing consideration, in this technical solution, the bottom of the liquid storage cavity 1101 may have a concave area 1101a, and the mounting post 160 for positioning the magnetic levitation 310 of the liquid amount detection unit 300 may be located in the concave area 1101a, so that local deepening of the liquid storage cavity 1101 may be achieved, buoyancy of the magnetic levitation 310 under the same depth position may be increased, and space may be provided for lifting of the magnetic levitation 310, for example, a space above the concave area 1101a in the liquid storage cavity 1101 is regarded as a main space of the liquid storage cavity 1101, and then, based on the foregoing setting, in the case that the liquid amount in the main area is small, the magnetic levitation 310 may reflect the liquid amount change in the main area through floating in the concave area 1101a, so that the detection range and the detection precision of the liquid amount detection unit 300 are further improved, and the user experience of the product is further improved.

In some possible examples, where the delivery system 10 includes a pumping unit 200, the input end of the pumping unit 200 is located within the recessed region 1101 a.

In this technical solution, the input end of the pumping unit 200 may be disposed in the recessed area 1101a, so that based on the foregoing arrangement, the pumping device may more fully pump the liquid in the liquid storage cavity 1101, thereby being beneficial to reducing the liquid loss in the liquid storage cavity 1101, improving the liquid utilization rate in the liquid storage cavity 1101, and reducing the cost of the cleaning process in practical application.

As shown in fig. 1-3, 13-16, in some examples, the delivery system 10 further includes: the accommodating unit 400 is formed with an open accommodating cavity 401, and the box body 110 is movably disposed in the accommodating unit 400 so that the box body 110 can be extended or retracted into the accommodating cavity 401.

In this technical solution, the delivery system 10 may further include a housing unit 400, where the housing unit 400 is formed with an open housing cavity 401, and the box body 110 is movably connected to the housing unit 400, so that the box body 110 may be pulled out of or pushed into the housing cavity 401, so that, based on the foregoing setting, in the process of delivering the cleaning agent by the delivery system 10, the liquid storage box 111 may be retracted into the housing cavity 401, and further, the delivery system 10 may further utilize the housing unit 400 to provide structural protection for the box body 110, so as to improve stability and reliability of the liquid storage cavity 1101; when filling of the cleaning agent or replacement of the container is required, the liquid storage box 111 can be extended out of the accommodating cavity, so that the operation of a user is facilitated, and the filling convenience of the cleaning agent is improved.

In practical applications, the accommodating unit 400 may be disposed in a cabinet of the laundry treating apparatus to ensure stability of the accommodating unit 400 and the dispensing unit 100.

As shown in fig. 17-19, in some possible examples, where the delivery system 10 is applied to a laundry treatment apparatus, the accommodation unit 400 is for placement proximate to the cleaning opening 23 of the laundry treatment apparatus, and where the case portion 110 is retracted into the accommodation cavity 401, the trim portion 140 covers the opening of the accommodation cavity 401 and the cleaning opening 23.

In this embodiment, when the delivery system 10 is applied to a laundry treatment apparatus, the accommodating unit 400 may be disposed near the cleaning opening 23 of the laundry treatment apparatus, and it will be appreciated that the laundry treatment apparatus generally has a drainage system or a filtering system 40, and accordingly, the housing assembly 20 of the laundry treatment apparatus may be provided with the cleaning opening 23 corresponding to the cleaning end 41 of the drainage system or the filtering system 40, so as to facilitate the cleaning operation of the drainage system or the filtering system 40 by a user periodically, and reduce the blocking probability of components or pipelines. The accommodating unit 400 provided in the embodiment of the present disclosure may be disposed close to the cleaning opening 23 of the laundry treatment apparatus, and accordingly, in a case where the box body 110 of the delivering unit 100 is retracted into the accommodating cavity 401 of the accommodating unit 400, the plaque 140 of the delivering unit 100 is disposed to cover the cleaning opening 23 while covering the opening of the accommodating cavity 401, so that on one hand, an independent covering member for the cleaning opening 23 may be avoided, which is beneficial to reducing the number of parts of the laundry treatment apparatus, and further, the production cost and the use cost of the laundry treatment apparatus may be reduced, and the possibility of misoperation of a user may be reduced; on the other hand, since the putting unit 100 is used for containing and putting the cleaning agent in the clothes treatment process, the use frequency is relatively high, the putting device and the cleaning port 23 are arranged in a concentrated manner, the probability that the user finds the cleaning port 23 in the process of putting the cleaning agent by the user is improved, the effect of reminding the user of cleaning the drainage system or the filtering system 40 is further achieved, the risk of blocking of the drainage system or the filtering system 40 is reduced, and the use experience of the user of the product is further improved.

It will be appreciated that the cabinet assembly 20 of the laundry treating apparatus may include a base 21 and a panel 22.

In some possible examples, the delivery system 10 further comprises: a slide rail unit disposed in the accommodating chamber 401; the slider unit is disposed on the box body 110, and the slider unit is slidably connected to the slide rail unit, so that the box body 110 can slidably extend out of or retract into the accommodating cavity 401.

In this technical solution, the delivery system 10 may further include a slide rail unit and a slider unit, where the slide rail unit and the slider unit are respectively disposed in the accommodating cavity 401 of the accommodating unit 400 and on the box body portion 110 of the delivery unit 100, and the slider unit is slidably connected to the slide rail unit, so that the box body portion 110 can slidably extend out of or retract into the accommodating cavity 401, which is beneficial to improving the stability and smoothness of the movement of the box body portion 110, and improving the operation convenience of the delivery system 10.

As shown in fig. 12 and 13, in some possible examples, the accommodating unit 400 further includes a first limiting structure 402, the delivering unit 100 further includes a second limiting structure 150, the second limiting structure 150 is detachably connected to the first limiting structure 402, and the second limiting structure 150 is connected to the first limiting structure 402 when the box portion 110 is retracted into the accommodating cavity 401.

In this technical solution, the accommodating unit 400 may be formed with a first limiting structure 402, and the delivering unit 100 may further include a second limiting structure 150, where the second limiting structure 150 is connected to the first limiting structure 402 when the box portion 110 is pushed into the accommodating cavity 401, so that the delivering system 10 may fix a relative position between the accommodating unit 400 and the delivering unit 100 based on a matching relationship between the first limiting structure 402 and the second limiting structure 150, so as to reduce a possibility that the delivering unit 100 is accidentally separated from the accommodating unit 400 in a use process.

It is understood that the receiving unit 400 may be used to fixedly mount the cabinet assembly 20 to a cleaning apparatus (e.g., a laundry treating apparatus).

As shown in fig. 15 and 16, in some possible examples, the first limiting structure 402 may be a fixing post, and the second limiting structure 150 may be a buckle, and the buckle may be detachably fastened to the fixing post, so that the first limiting structure 402 and the second limiting structure 150 may be fixed by means of fastening.

As shown in fig. 1-3, in some examples, launch conduit 500 includes: a joint portion 510 disposed in the liquid storage chamber 1101 for fitting to a container mouth of the fluid container 10'; the suction pipe 520 has one end detachably connected to the joint portion 510 and the other end formed with an input end.

In this embodiment, the dispensing pipeline 500 may include a joint portion 510 and a suction tube 520, where the joint portion 510 is disposed in the liquid storage chamber 1101 and is used to adapt to a container opening of the fluid container 10', the suction tube 520 and the joint portion 510 are in a detachable connection relationship, and in a case where the suction tube 520 is connected to the joint portion 510, an input end of the dispensing pipeline 500 is formed at an end of the suction tube 520 away from the joint portion 510, and correspondingly, in a case where the suction tube 520 is separated from the joint portion 510, an input end of the dispensing pipeline 500 is formed at the joint portion 510. Thus, based on the above arrangement, when the fluid is contained in the liquid storage chamber 1101, the suction pipe 520 may be disposed at the joint 510, so as to increase the line length of the delivery pipe 500 in the liquid storage chamber 1101, and further expand the distribution range of the delivery pipe 500 in the liquid storage chamber 1101; in the case where the fluid container 10' is accommodated in the liquid storage chamber 1101, the suction pipe 520 may be removed from the structure portion so that the joint portion 510 is engaged with the container mouth of the fluid container 10', thereby facilitating the introduction of the fluid in the fluid container 10' through the delivery pipe 500.

It will be appreciated that a cleaning agent container, such as an ink cartridge for a cartridge type cleaning agent or a capsule for a capsule type cleaning agent, is suitable for machine cleaning, and the container mouth thereof generally has a connection structure, such as a screw structure or a snap structure, and accordingly, the joint portion 510 is adapted to the container mouth, that is, the joint portion 510 has a shape capable of being mutually connected and mated with the connection structure, so that the joint portion 510 can be abutted to the container mouth. In practical applications, the connector portion 510 and the liquid storage box 111 may be detachably connected, and accordingly, the number of the connector portions 510 may be plural, and the shape of each connector portion 510 may be different, so that in the case of requiring a fluid container 10' with a different butt-joint connection structure, a user may conveniently select different connector portions 510.

As shown in fig. 3, in some examples, with suction tube 520 connected to fitting 510, the input end is disposed proximate to the bottom wall of liquid storage chamber 1101.

In this technical scheme, under the condition that suction tube 520 is connected in joint portion 510, can set up that the input of throwing in pipeline 500 is close to in the diapire of stock solution chamber 1101 and arrange, that is set up that suction tube 520 is kept away from in the end of joint portion 510 and is close to the diapire of stock solution chamber 1101 promptly to based on the aforesaid setting, can be convenient for throw in pipeline 500 and guide the liquid in stock solution chamber 1101 bottom region, and then be favorable to improving the cleaner utilization ratio in stock solution chamber 1101 at clothing processing in-process, reduce the cleaner loss in stock solution chamber 1101, further reduce the cost of clothing processing, improve the user experience of product.

It should be understood that, as shown in fig. 3, the suction tube 520 may be an L-shaped tube, and in practical applications, the specific shape of the suction tube 520 may be set according to practical requirements, that is, the suction tube 520 may also be a straight tube, a curved tube, etc., which is not limited herein.

As shown in fig. 4 to 9, the cover 120 has at least two operation ends 1201; with the cover body 120 covering the dispensing opening 1102, one operation space 1202 is formed between each of the operation ends 1201 and the cartridge body 110.

In this embodiment, the cover 120 has an operation end 1201, and in practical applications, the operation end 1201 may be used to receive a driving force, that is, an external force for driving the cover 120 to move relative to the box 110 to open or close the liquid inlet, for example, in a case where the user manually operates the cover 120, the operation end 1201 may be used to contact the hand of the operator and receive the driving force applied by the hand of the operator; accordingly, in the case where the cover 120 covers the dispensing opening 1102, an operation space 1202 is formed between the operation end 1201 and the case 110, and the operation space 1202 may provide a passable space for a user's hand to approach and contact the operation end 1201, thereby facilitating the user to operate the cover 120.

The number of the operation ends 1201 is at least two, and in the case that the cover body 120 covers the dispensing opening 1102, an operation space 1202 is formed between each operation end 1201 and the box body 110, so that the hands of a user can conveniently contact with a plurality of parts of the cover body 120 (such as opposite sides, which are convenient for the user to hold), and the driving force is simultaneously applied to the plurality of parts of the cover body 120, so that in the operation process of switching the liquid dispensing opening from the covering state to the opening state, on one hand, the contact area between the cover body 120 and the hands of the user can be advantageously increased, the feasible contact position between the cover body 120 and the hands of the user can be expanded, the convenience of applying force by the user in the operation process can be further improved, the opening difficulty of the dispensing opening 1102 can be reduced, and the use experience of the product can be improved; on the other hand, the cover 120 is also beneficial to avoiding bearing the driving force with concentrated distribution, improving the stress dispersibility and balance of the cover 120, further reducing the probability of damaging the cover 120 in practical application and reducing the maintenance and use cost of the delivery unit 100.

It is understood that the at least two operating ends 1201 may be at least two different ends of the cover 120, for example, in the case where the cover 120 is of a plate-shaped structure, the operating ends 1201 may be plate ends in a length direction or a width direction of the plate-shaped structure, and the at least two operating ends 1201 may be adjacent to each other or may be spaced apart from each other.

Illustratively, as shown in fig. 7, the cover 120 may have a generally rectangular plate-like structure as a whole (preferably, the cover 120 is generally square), so that there are four ends in the length direction and the width direction of the cover 120, so that for the cover 120 having a rectangular plate-like structure, the number of the aforementioned operating ends 1201 may be two or more and four or less, and in consideration of the connection fit between the cover 120 and the case 110, the number of the operating ends 1201 of the cover 120 having a rectangular plate-like structure may be three or less, that is, in practical use, one end in the length or width direction of the cover 120 may be used to connect the case 110. It is understood that the shape of the cover 120 may be, but not limited to, a rectangular plate-like structure, and may be other polygonal plate-like structures, such as a triangular plate-like structure, a pentagonal plate-like structure, a hexagonal plate-like structure, etc., and accordingly, the number of the operating ends 1201 may also be set according to the specific shape and practical requirements of the cover 120.

It should be noted that, some dispensing units 100 in the conventional technology generally include a case body and a cover body, the case body is provided with an open liquid storage space, the cover body is used for covering or opening the opening of the liquid storage space, and a small notch structure is often provided on one side of the case body corresponding to the cover body, and when the cover body covers the opening, a user only can stretch a single fingernail into the case body through the small notch structure located on one side of the cover body if the user needs to open the opening, so that the user can apply force to the case body only from a single position, the operation difficulty is relatively high, the use experience of the user is poor, and the user is inconvenient to regulate the direction and the size of the application force due to the space constraint, so that the damage of the cover body is easily caused. Based on the foregoing arrangement, the dispensing unit 100 provided in the embodiment of the disclosure can increase the contact area between the cover 120 and the hand of the user, expand the feasible contact position between the cover 120 and the hand of the user, improve the convenience of force application of the user in the operation process, and facilitate improvement of the force dispersion and balance of the cover 120, thereby reducing the damage probability of the cover 120 in practical application.

As shown in fig. 4-9, in some possible examples, the cover portion 120 has a uniform width with the cassette portion 110, and the cover portion 120 has an operating end 1201.

The cover 120 has an operation end 1201, and in practical applications, the operation end 1201 may be used to receive a driving force, that is, an external force for driving the cover 120 to move relative to the box 110 to open or close the liquid inlet, for example, in a case where a user manually operates the cover 120, the operation end 1201 may be used to contact an operator's hand and receive a driving force applied by the operator's hand; accordingly, in the case where the cover 120 covers the dispensing opening 1102, an operation space 1202 is formed between the operation end 1201 and the case 110, and the operation space 1202 may provide a passable space for a user's hand to approach and contact the operation end 1201, thereby facilitating the user to operate the cover 120.

Meanwhile, the width of the cover 120 is consistent with the width of the box 110, so that the cover 120 has a relatively high width, thereby facilitating the operation of the user's hand with a large opening degree, reducing the possibility of mutual interference between fingers during the operation of the user, and further improving the operation convenience of the cover 120. Accordingly, when the size of the cover 120 is relatively large, the user can grasp and perform the operation of the cover 120, that is, the two fingers of the user can apply force to the one operation end 1201, which is advantageous for further improving the convenience of the operation of the cover 120.

It will be appreciated that the width of the cover 120 corresponds to the width of the case 110, that is, the cover 120 has a width similar to (e.g., the same as or slightly smaller than) the width of the case 110, and has an overall shape (e.g., the overall shape corresponding to the case 110) that matches the case 110, so that the dispensing unit 100 may have a high aesthetic appearance while ensuring a high width of the cover 120 for convenience of operation by a user.

Illustratively, the width of the cover 120 may be greater than or equal to 0.8 times the width of the box 110 and less than or equal to the width of the box 110, so that, on one hand, the width of the box 110 and the width of the cover 120 may have a higher consistency, thereby facilitating the hand stretching operation of the user and further improving the operation convenience of the cover 120; on the other hand, the cover 120 can be prevented from being too wide, which is advantageous in ensuring the compactness of the dispensing unit 100 and improving the aesthetic appearance of the dispensing unit 100. Illustratively, the width of the cover 120 may be, but is not limited to, 0.8 times, 0.85 times, 0.9 times, 1 time, etc. the width ratio between the cover 120 and the box 110 may be specifically set in connection with actual requirements, and is not excessively limited herein.

It is to be understood that, in the case where the cover 120 has a plate-like structure, the operation end 1201 may be a plate end in the width direction of the plate-like structure.

It should be noted that, some dispensing units 100 in the conventional technology generally include a case body and a plurality of cover bodies, the case body is provided with a plurality of open liquid storage spaces, the cover bodies are used for covering or opening the openings of the liquid storage spaces in a one-to-one correspondence manner, so that the size of the cover bodies is often smaller than that of the case body, and a small notch structure is usually provided on one side of the case body corresponding to the cover bodies, when the cover bodies cover the openings, a user only can stretch a single fingernail into the case body through the small notch structure on one side of the cover bodies, so that the operation difficulty is relatively high, the user experience is poor, and due to space constraint, the user is inconvenient to regulate the force application direction and the force application size, and the cover bodies are easy to damage. The releasing unit 100 provided in the embodiment of the present disclosure is based on the foregoing arrangement, so that the width of the cover 120 can be increased, thereby being beneficial to increasing the contact area between the cover 120 and the hand of the user, facilitating the application of force by the user in the operation process, and further reducing the damage probability of the cover 120 in practical application.

In some possible examples, the operating end 1201 may be provided with anti-slip features, which further facilitate the application of force to the cover 120 by the user.

In some possible examples, the length of the operation space 1202 is greater than or equal to the length of the operation end 1201, so that the operation space 1202 corresponds to the whole edge of the cover 120, the distribution range of the operation space 1202 is enlarged, and the operation convenience of the cover 120 is further improved. It will be understood that, when the cover 120 is a rectangular plate-like structure, for example, the operating end 1201 is one end in the length direction of the rectangular plate-like structure, and accordingly, the operating end 1201 extends along the length direction of the rectangular plate-like structure, and similarly, if the operating end 1201 is one end in the length direction of the rectangular plate-like structure, the operating end 1201 extends along the width direction of the rectangular plate-like structure; accordingly, the longitudinal direction of the operation space 1202 coincides with the longitudinal direction of the operation end 1201.

As shown in fig. 4, 5, 7, and 9, in some examples, the number of the operation ends 1201 is two, and the two operation ends 1201 face away from each other.

In this technical solution, the number of the operation ends 1201 may be two, and the two operation ends 1201 deviate from each other, that is, the two ends of the cover 120 deviate from each other may be the two operation ends 1201, so that based on the foregoing arrangement, the interval distance between the two operation ends 1201 can be enlarged, and further, when the user can apply force to different parts of the cover 120 at the same time, the stress balance of the cover 120 in the use process is further improved, which is favorable to further reducing the damage probability of the cover 120 and improving the convenience of opening the delivery port 1102.

It will be appreciated that, when the two operating ends 1201 are away from each other, when the lid 120 covers the dispensing opening 1102, two operating spaces 1202 are correspondingly formed between the lid 120 and the case 110.

It can be appreciated that in practical application, the size of the cover 120 can be set in combination with practical requirements, and under the condition that the size of the cover 120 is relatively smaller, a user can perform the operation of the cover 120 with a single finger, and based on the foregoing setting, the distance between the two operation spaces 1202 can be relatively larger, so that the hands of the user can operate with a larger opening degree, which is beneficial to reducing the possibility of mutual interference between the fingers in the operation process of the user, and is beneficial to further improving the operation convenience of the cover 120. Accordingly, when the size of the cover 120 is relatively large, the user can grasp and perform the operation of the cover 120, that is, the two fingers of the user can apply force to the one operation end 1201, which is advantageous for further improving the convenience of the operation of the cover 120.

In some possible examples, the cover 120 has a width similar to (e.g., the same as or slightly smaller than) the width of the case 110, and has an overall shape that is compatible with the case 110 (e.g., an overall shape that is compatible with the case 110), so that the dispensing unit 100 can have a high aesthetic appearance while ensuring a high width of the cover 120 for easy operation by a user.

In some possible examples, the distance between the two mutually facing operating ends 1201 is adapted to the width of the box body 110, for example, the distance between the two mutually facing operating ends 1201 may be greater than or equal to 0.5 times the width of the box body 110 and less than or equal to 0.95 times the width of the box body 110, so that, on one hand, the distance between the two mutually facing operating ends 1201 may be greater, the span between the operating ends 1201 and the overall width of the cover body 120 may be increased, thereby facilitating the user's hand stretching operation and further improving the convenience of operation of the cover body 120; on the other hand, the cover 120 can be prevented from being too wide, which is advantageous in ensuring the compactness of the dispensing unit 100 and improving the aesthetic appearance of the dispensing unit 100. Illustratively, the distance between the two operating ends 1201 facing away from each other may be, but is not limited to, 0.55 times, 0.6 times, 0.7 times, 0.8 times, 0.9 times, etc. the foregoing distance may be specifically set in connection with the actual requirement, and is not excessively limited herein.
