Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing devices, in particular to a liquid delivery device for clothing processing devices and a clothing processing device. Background Art

[0002] Existing washing machines have the function of automatic detergent dispensing, which requires the washing machine to have the function of automatic detection of detergent residue. Washing machines generally detect the amount of detergent residue by the floating state of a magnetic float at different detergent residues. For example, in the prior art CN202210905976.8, a cartridge-type automatic dispensing system is disclosed, in which the alarm device includes a float, a magnet and a reed switch assembly. The float is arranged in the cavity of the temporary storage chamber assembly and rises and falls with the liquid level of the detergent. The magnet is arranged in the float and rises and falls synchronously with the float. A reed switch assembly paired with the magnet is provided at the bottom of the temporary storage chamber assembly. A column is provided in the temporary storage chamber assembly, and the column is arranged vertically to the bottom of the temporary storage chamber assembly. The float is mounted on the column and can move up and down relative to the column. In the prior art, the remaining detergent amount is detected by the detergent flowing into the temporary storage chamber. The detergent flows into the temporary storage chamber due to the height difference between the temporary storage chamber and the liquid storage box. The magnetic float is arranged in the cavity of the temporary storage chamber assembly. It is also necessary to set a sliding column in the cavity of the temporary storage chamber assembly, and the float is also required to be mounted on the column. The structure is relatively complicated and the installation is inconvenient. Utility Model Content

[0003] In order to overcome the disadvantage of the relatively complex structure of the liquid delivery device in the prior art, the utility model provides a liquid delivery device for a clothing processing device and a clothing processing device, which have a simpler and more stable structure.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a liquid delivery device of a clothing processing device, comprising a liquid storage box and a magnetic float arranged in the inner cavity of the liquid storage box, the liquid storage box is provided with a liquid outlet valve, the liquid outlet valve includes a valve seat with one end extending into the inner cavity of the liquid storage box, the magnetic float is connected to the valve seat to limit the floating trajectory of the magnetic float.

[0005] In the above technical solution, the magnetic float is directly arranged in the inner cavity of the liquid storage box. When the detergent residue in the inner cavity of the liquid storage box changes, the floating trajectory of the magnetic float can be directly affected by the buoyancy to detect the detergent residue. Among them, the magnetic float is connected to the valve seat to limit the floating trajectory of the magnetic float, so that the floating trajectory of the magnetic float changes with the regularity of the detergent residue in the inner cavity of the liquid storage box, which is conducive to detecting the change of the detergent residue in the inner cavity of the liquid storage box according to the change of the floating trajectory of the magnetic float. The magnetic float is directly arranged in the inner cavity of the liquid storage box, and then the floating trajectory of the magnetic float is limited by connecting to the valve seat. There is no need for a temporary storage cavity other than the liquid storage box, and the structure is simpler. The valve seat is stronger than the thin wall of the liquid storage box. Compared with the solution in the prior art that is set on the thin wall by a sliding column, this solution connects the magnetic float to the valve seat, which has less impact on the liquid storage box and better connection strength of the magnetic float.

[0006] The utility model is further configured as follows: it also includes a fixed box body and a movable box body, the movable box body can be removably assembled to the fixed box body, the liquid storage box can be detachably installed in the movable box body, and the fixed box body is provided with a magnetic sensor for detecting the magnetic float and a liquid inlet pipe for opening the liquid outlet valve.

[0007] In the above technical solution, when assembling the liquid storage box, the liquid storage box can be first assembled into the mobile box body, and then the mobile box body can be inserted into the fixed box body to realize the assembly of the liquid storage box. The assembly process is more convenient, which is conducive to improving production efficiency. In addition, when it is necessary to replace the liquid storage box or add detergent, the mobile box body is pulled out from the fixed box body, and then the liquid storage box is disassembled from the mobile box body, that is, the liquid storage box or detergent is replaced. At the same time, the assembly of the liquid storage box can be more convenient, making the replacement of the liquid storage box and the addition of detergent more convenient; and it can also be more convenient for maintenance. Among them, the floating state of the magnetic float in the inner cavity of the liquid storage box is detected by the magnetic sensor arranged on the fixed box body, and the remaining detergent is detected. In addition, the magnetic sensor is arranged on the fixed box body, and the liquid storage box is not electrically connected to the fixed box body. When assembling the liquid storage box, no electrical connection is required, and the liquid inlet pipe for opening the liquid outlet valve is arranged on the fixed box body. The liquid storage box is installed in the mobile box body, and then the mobile box body is inserted into the fixed box body. The liquid inlet pipe opens the liquid outlet valve, and the liquid storage box and the liquid inlet pipe are connected. There is no need to connect the pipeline between the liquid storage box and the fixed box body. Specifically, when disassembling or assembling, the liquid storage box and the fixed box body can remain relatively independent and do not interfere with each other, and the disassembly or assembly of the liquid storage box can be more convenient. Among them, the magnetic sensor is arranged on the fixed box body, and the fixed box body is fixed and immovable. The electrical connection is arranged on the fixed box body, which is more stable and not easy to loosen, which is conducive to reducing the failure rate. In addition, the additional components on the liquid storage box are reduced. When the liquid storage box needs to be replaced, only the liquid storage box needs to be replaced, which can reduce the cost of replacing the liquid storage box.

[0008] The utility model is further configured as follows: the magnetic float is hinged to the valve seat so that the magnetic float can flip and float relative to the valve seat.

[0009] In the above technical solution, when the amount of detergent remaining in the inner cavity of the liquid storage box changes, the magnetic float flips and floats relative to the valve seat, the distance between the magnetic float and the magnetic sensor changes, and the magnetic sensor detects the change in the amount of detergent remaining, thereby completing the detection of the amount of detergent remaining. The magnetic float is hinged to the valve seat, and no sliding column is required, so the structure is simpler. The magnetic float is hinged to the valve seat, and there is a lever effect between the magnetic float and the hinged position, so it is not easy to get stuck.

[0010] The utility model is further configured as follows: an air supply valve is installed on the liquid storage box, and the air supply valve unidirectionally connects the inner cavity and the outside of the liquid storage box so that the gas outside the liquid storage box can enter the inner cavity of the liquid storage box.

[0011] In the above technical solution, after the detergent in the inner cavity of the liquid storage box flows out, the detergent in the liquid storage box is reduced, and a negative pressure is formed in the inner cavity of the liquid storage box. The liquid storage box is provided with an air replenishing valve, and the air replenishing valve is opened, so that the gas outside the liquid storage box enters the inner cavity of the liquid storage box to supplement the negative pressure caused by the outflow of detergent, balance the air pressure in the inner cavity of the liquid storage box, and ensure the normal outflow of detergent. Among them, the air replenishing valve connects the inner cavity and the outside of the liquid storage box in one direction, and only allows gas to enter the inner cavity of the liquid storage box from the outside of the liquid storage box, which can prevent the detergent from overflowing or being contaminated, and ensure the sealing of the liquid storage box. In addition, the air replenishing valve connects the inner cavity and the outside of the liquid storage box in one direction. Affected by the pressure difference between the inner cavity of the liquid storage box and the liquid storage box, the external gas will automatically enter and balance the air pressure in the inner cavity of the liquid storage box. The structure is simple, which is conducive to reducing costs and failure rates.

[0012] The utility model is further configured as follows: the liquid storage box includes a liquid box body with openings at both ends, a front cover detachably connected to and closing the front end opening of the liquid box body, and a rear cover installed at and closing the rear end opening of the liquid box body.

[0013] In the above technical solution, both the front and rear ends of the liquid box body are open, and the front cover is detachably connected to the front opening of the liquid box body and closes the front opening. After the detergent in the inner cavity of the liquid storage box is used up, the detergent can be added from the opening by removing the front cover, which makes it more convenient to add detergent and can be repeatedly added. There is no need to replace the liquid storage box after each use of the detergent, which is conducive to reducing the user's use cost, thereby improving the user's use experience, and is also more environmentally friendly. In addition, when assembling the magnetic float and the liquid outlet valve, both the front and rear ends of the liquid box body are open, which increases the operable space and makes assembly more convenient. In addition, dividing the complex liquid storage box into three parts for manufacturing can reduce the manufacturing difficulty and help reduce manufacturing costs.

[0014] The utility model is further configured as follows: the valve seat is fixed to the rear cover.

[0015] In the above technical solution, the valve seat is fixed to the back cover, and the magnetic float is connected to the valve seat. During assembly, the magnetic float and the valve seat can be assembled first, and then the back cover can be installed on the rear end opening of the liquid box body and the rear end opening can be closed to complete the installation of the magnetic float. This can avoid the magnetic float being assembled in the inner cavity of the liquid storage box. The magnetic float and the valve seat can be installed outside first. There is no space restriction, which makes installation and operation easier and facilitates production and assembly.

[0016] The utility model is further configured as follows: a sealing ring is provided at the connection between the rear cover and the liquid box body.

[0017] In the above technical solution, a sealing ring is provided at the connection between the rear cover and the liquid box body, thereby preventing detergent leakage, thereby preventing the liquid delivery device from being damaged due to detergent leakage, and helping to improve the electrical safety of the liquid delivery device.

[0018] The utility model is further configured as follows: the fixed box body comprises a box body and a box cover which is covered on the top of the box body, the box cover is arranged above the liquid storage box, and the magnetic sensor is installed on the box cover so that the magnetic sensor is arranged above the liquid storage box.

[0019] In the above technical solution, when it is necessary to assemble a fixed box body, the components of the box body and the box cover can be assembled separately first, and then the box cover is placed on the box body to complete the assembly of the fixed box body, avoiding direct assembly in the fixed box body. The components of the box body and the box cover are assembled separately, and the operating space is larger, which is convenient for assembling the internal components of the fixed box body.

[0020] The utility model is further configured such that: when the magnetic float is at the lowest position, the height of the upper end surface of the magnetic float is lower than the height of the upper end surface of the valve seat, and the height of the lower end surface of the magnetic float is higher than the height of the lower end surface of the valve seat.

[0021] In the above technical solution, when the magnetic float is at the lowest position, the height of the upper end surface of the magnetic float is lower than the height of the upper end surface of the valve seat, and the height of the lower end surface of the magnetic float is higher than the height of the lower end surface of the valve seat. The magnetic float is between the upper end surface and the upper end surface of the valve seat. During assembly, the magnetic float will not interfere with the opening when it is extended into the opening, which is convenient for the installation of the back cover. It should be noted that the upper end surface of the magnetic float refers to the end away from the hinge connection between the magnetic float and the valve seat, and the lower end surface of the magnetic float refers to the end close to the hinge connection between the magnetic float and the valve seat.

[0022] The utility model also shows a clothing processing device, comprising a shell and a drum installed in the shell, and also comprising any of the above-mentioned liquid delivery devices, wherein the liquid delivery device is installed on the front side of the shell.

[0023] In the above technical solution, the clothing processing device adopts the liquid dispensing device of any of the above-mentioned liquid dispensing devices, and the magnetic float is directly arranged in the inner cavity of the liquid storage box. When the detergent residue in the inner cavity of the liquid storage box changes, the floating trajectory of the magnetic float can be directly affected by the buoyancy, and the detergent residue can be detected more accurately. Among them, the magnetic float is connected to the valve seat, and the floating trajectory of the magnetic float is limited, so that the floating trajectory of the magnetic float changes with the regularity of the detergent residue in the inner cavity of the liquid storage box, which is conducive to detecting the change of the detergent residue in the inner cavity of the liquid storage box according to the change of the floating trajectory of the magnetic float. In addition, the liquid dispensing device is installed on the front side of the shell, which conforms to the user's usage habits and is convenient for the user to use the liquid dispensing device. It should be noted that the front side of the shell refers to the side where the user stands when using the washing machine.

[0024] The utility model has the beneficial effect that the magnetic float is directly arranged in the inner cavity of the liquid storage box, and when the detergent residue in the inner cavity of the liquid storage box changes, the floating track of the magnetic float can be directly affected by buoyancy, so that the detergent residue can be detected more accurately.

[0031] In the description of this embodiment, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it cannot be understood as a limitation on the utility model. In addition, if the terms "first", "second", and "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] Embodiment 1:

[0034] like Figures 1 to 5 As shown, a liquid delivery device of a clothing treatment device comprises a liquid storage box 1.1 and a magnetic float 1.3 arranged in the inner cavity of the liquid storage box 1.1, a liquid outlet valve 1.5 is arranged on the liquid storage box 1.1, and the liquid outlet valve 1.5 comprises a valve seat 1.2 at one end extending into the inner cavity of the liquid storage box 1.1, and the magnetic float 1.3 is connected to the valve seat 1.2 to limit the floating track of the magnetic float 1.3.

[0035] In this embodiment, the magnetic float 1.3 is directly set in the inner cavity of the liquid storage box 1.1. When the detergent residue in the inner cavity of the liquid storage box 1.1 changes, the floating trajectory of the magnetic float 1.3 can be directly affected by the buoyancy to detect the detergent residue. Among them, the magnetic float 1.3 is connected to the valve seat 1.2, and the floating trajectory of the magnetic float 1.3 is limited, so that the floating trajectory of the magnetic float 1.3 changes with the regularity of the detergent residue in the inner cavity of the liquid storage box 1.1, which is conducive to detecting the change of the detergent residue in the inner cavity of the liquid storage box 1.1 according to the change of the floating trajectory of the magnetic float 1.3. The magnetic float 1.3 is directly set in the inner cavity of the liquid storage box 1.1, and then the floating trajectory of the magnetic float 1.3 is limited by connection with the valve seat 1.2. There is no need for a temporary storage cavity other than the liquid storage box 1.1, and the structure is simpler. The valve seat 1.2 is stronger than the thin wall of the liquid storage box 1.1. Compared with the solution in the prior art where a sliding column is set on a thin wall, this solution connects the magnetic float 1.3 to the valve seat 1.2, which has less impact on the liquid storage box 1.1 and has better connection strength of the magnetic float 1.3.

[0036] Specifically, if Figure 3 and 4As shown, the magnetic float 1.3 includes a magnetic part 1.3.2, a connector 1.3.1 and a fastener 1.3.3, wherein the connector 1.3.1 is connected to the valve seat 1.2, a mounting position is provided on the connector 1.3.1, the magnetic part 1.3.2 is arranged in the mounting position, and then fixed by the fastener 1.3.3. Of course, a seal can be provided between the connector 1.3.1 and the fastener 1.3.3 to prevent the magnetic part 1.3.2 from contacting with the detergent, contaminating the detergent or damaging the magnetic part 1.3.2. Among them, the connector 1.3.1 and the fastener 1.3.3 are made of a material with a lower density to prevent the magnetic float 1.3 from being too heavy and unable to float with the change of the detergent residue in the liquid storage box 1.1. Of course, in other embodiments, the magnetic float includes a float body and a magnetic part, and the float body is fully or partially covered with the magnetic part by integral injection molding, which reduces the connection relationship, has greater strength and rigidity, reduces parts, and is conducive to reducing costs. Among them, it is preferred that the entire package is integrally injection molded to prevent the magnetic part from contacting with the detergent, contaminating the detergent or damaging the magnetic part.

[0037] Specifically, Figure 5As shown, it also includes a fixed box body 4 and a mobile box body 5, the mobile box body 5 can be removably assembled to the fixed box body 4, the liquid storage box 1.1 can be detachably installed in the mobile box body 5, and the fixed box body 4 is provided with a magnetic sensor 2 for detecting the magnetic float 1.3 and a liquid inlet pipe 3.1 for opening the liquid outlet valve 1.5. When assembling the liquid storage box 1.1, the liquid storage box 1.1 can be assembled into the mobile box body 5 first, and then the mobile box body 5 is inserted into the fixed box body 4, so that the assembly of the liquid storage box 1.1 can be realized, and the assembly process is more convenient, which is conducive to improving production efficiency. In addition, when it is necessary to replace the liquid storage box 1.1 or add detergent, the mobile box body 5 is pulled out from the fixed box body 4, and then the liquid storage box 1.1 is disassembled from the mobile box body 5, that is, the liquid storage box 1.1 or the detergent is replaced. At the same time, the assembly of the liquid storage box 1.1 can be realized more conveniently, making the replacement of the liquid storage box 1.1 and the addition of detergent more convenient; and it can also be more convenient for maintenance. The floating state of the magnetic float 1.3 in the inner cavity of the liquid storage box 1.1 is detected by the magnetic sensor 2 arranged on the fixed box body 4, and the remaining amount of detergent is detected. In addition, the magnetic sensor 2 is arranged on the fixed box body 4, and the liquid storage box 1.1 is not electrically connected to the fixed box body 4, and no electrical connection is required when assembling the liquid storage box 1.1, and the liquid inlet pipe 3.1 for opening the liquid outlet valve 1.5 is arranged on the fixed box body 4, and the liquid storage box 1.1 is installed in the movable box body 5, and then the movable box body 5 is inserted into the fixed box body 4, and the liquid inlet pipe 3.1 opens the liquid outlet valve 1.5, so that the liquid storage box 1.1 and the liquid inlet pipe 3.1 are connected, and there is no need to connect the pipeline between the liquid storage box 1.1 and the fixed box body 4. Specifically, when disassembling or assembling, the liquid storage box 1.1 and the fixed box body 4 can remain relatively independent and do not interfere with each other, and the disassembly or assembly of the liquid storage box 1.1 can be more convenient. Among them, the magnetic sensor 2 is arranged on the fixed box body 4, and the fixed box body 4 is fixed and immovable. The electrical connection is arranged on the fixed box body 4 to be more stable and not easy to loosen, which is conducive to reducing the failure rate; at the same time, the magnetic sensor 2 is arranged on the fixed box body 4, and when the movable box body 5 is not installed in place, the magnetic sensor 4 cannot detect the magnetism and will be triggered, so as to detect the in-place status of the movable box body 5. In addition, the additional components on the liquid storage box 1.1 are reduced, and when the liquid storage box 1.1 needs to be replaced, only the liquid storage box 1.1 needs to be replaced, which can reduce the cost of replacing the liquid storage box 1.1.

[0038] The magnetic sensor 2 can be a suitable sensor capable of sensing magnetism, such as a reed switch, a magnetoresistive sensor chip, etc.

[0039] Among them, Figures 1 to 4As shown, the magnetic float 1.3 is hinged to the valve seat 1.2 so that the magnetic float 1.3 can flip and float relative to the valve seat 1.2. When the detergent residue in the inner cavity of the liquid storage box 1.1 changes, the magnetic float 1.3 flips and floats relative to the valve seat 1.2, and the distance between the magnetic float 1.3 and the magnetic sensor 2 changes. The magnetic sensor 2 detects the change in the detergent residue, and then completes the detection of the detergent residue. Among them, the magnetic float 1.3 is hinged to the valve seat 1.2, and no sliding column is required, the structure is simpler, and the magnetic float 1.3 is hinged to the valve seat 1.2, and there is a lever effect between the magnetic float 1.3 and the hinge position, which is not easy to get stuck. Specifically, in this embodiment, a hinge shaft is provided on the magnetic float 1.3, and a hinge hole is provided on the valve seat 1.2. The hinge shaft is penetrated in the hinge hole, and the magnetic float 1.3 flips and floats with the hinge shaft axis as the rotation axis. Among them, the end face of the valve seat 1.2 is provided with a protrusion protruding from the end face, and the hinge hole is provided on the protrusion. In addition, the valve seat 1.2 is provided with a liquid outlet protruding toward the bottom wall of the liquid storage box 1.1 on the side where the magnetic float 1.3 is at the lowest position. Of course, it can be understood that in another embodiment, the valve seat 1.2 is provided with a hinge shaft, and the magnetic float 1.3 is provided with a hinge hole, and the hinge shaft is passed through the hinge hole. It should be noted that the highest and lowest floating positions of the magnetic float 1.3 are both within the effective detection range of the magnetic sensor 2.

[0040] Specifically, Figure 1 and Figure 2 As shown, the liquid storage box 1.1 is equipped with an air replenishing valve 1.6, which unidirectionally connects the inner cavity and the outside of the liquid storage box 1.1, so that the gas outside the liquid storage box 1.1 can enter the inner cavity of the liquid storage box 1.1. After the detergent in the inner cavity of the liquid storage box 1.1 flows out, the detergent in the liquid storage box 1.1 is reduced, and a negative pressure is formed in the inner cavity of the liquid storage box 1.1. The air replenishing valve 1.6 is installed on the liquid storage box 1.1. When the air replenishing valve 1.6 is opened, the gas outside the liquid storage box 1.1 enters the inner cavity of the liquid storage box 1.1, replenishes the negative pressure caused by the outflow of detergent, balances the air pressure in the inner cavity of the liquid storage box 1.1, and ensures the normal outflow of detergent. Among them, the air replenishing valve 1.6 unidirectionally connects the inner cavity and the outside of the liquid storage box 1.1, and only allows gas from the outside of the liquid storage box 1.1 to enter the inner cavity of the liquid storage box 1.1, which can prevent the detergent from overflowing or being contaminated, and ensure the sealing of the liquid storage box 1.1. In addition, the air supply valve 1.6 unidirectionally connects the inner cavity and the outside of the liquid storage box 1.1. Affected by the pressure difference between the inner cavity of the liquid storage box 1.1 and the air pressure of the liquid storage box 1.1, the external air will automatically enter to balance the air pressure in the inner cavity of the liquid storage box 1.1. The structure is simple, which is conducive to reducing costs and failure rates.

[0041] Specifically, Figure 2As shown, the liquid storage box 1.1 includes a liquid box body 1.1.1 with openings at both ends, a front cover 1.1.2 that is detachably connected to the front opening of the liquid box body 1.1.1 and closes the front opening, and a rear cover 1.1.3 that is installed at the rear opening of the liquid box body 1.1.1 and closes the rear opening. The liquid box body 1.1.1 has openings at both ends, and the front cover 1.1.2 is detachably connected to the front opening of the liquid box body 1.1.1 and closes the front opening. After the detergent in the inner cavity of the liquid storage box 1.1 is used up, the detergent can be added from the opening by removing the front cover 1.1.2, which can be more convenient to add detergent, and the detergent can be added repeatedly. It is not necessary to replace the liquid storage box 1.1 every time the detergent is used up, which is conducive to reducing the user's use cost, thereby improving the user's use experience, and is also more environmentally friendly. In addition, when assembling the magnetic float 1.3 and the liquid outlet valve 1.5, the front and rear ends of the liquid box body 1.1.1 are open, which increases the operable space and makes assembly more convenient. In addition, manufacturing the complex liquid storage box 1.1 by dividing it into three parts can reduce the difficulty of manufacturing and help reduce the manufacturing cost. Specifically, in this embodiment, the front cover 1.1.2 is threadedly connected to the liquid box body 1.1.1, and the threaded connection is easy to disassemble, simple and low-cost; of course, in order to prevent leakage, a sealing gasket can be provided between the front cover 1.1.2 and the liquid box body 1.1.1. It can be understood that the front cover and the liquid box body can also adopt other detachable connections. For example, in another embodiment, the front cover and the liquid box body are fixed by snap connection.

[0042] In this embodiment, the rear cover 1.1.3 is threadedly connected to the liquid box body 1.1.1, and the threaded connection is easy to disassemble, simple and low-cost; of course, in order to prevent leakage, a sealing gasket can be provided between the rear cover 1.1.3 and the liquid box body 1.1.1. It is understandable that the rear cover and the liquid box body can also be connected in other detachable ways. For example, in another embodiment, the rear cover and the liquid box body are connected by ultrasonic hot melt, and the ultrasonic hot melt connection has better sealing performance.

[0043] Among them, Figure 2 As shown, the valve seat 1.2 is fixed to the rear cover 1.1.3. The magnetic float 1.3 is connected to the valve seat 1.2. When assembling, the magnetic float 1.3 and the valve seat 1.2 can be assembled first, and then the rear cover 1.1.3 is installed on the rear opening of the liquid box body 1.1.1 and the rear opening is closed to complete the installation of the magnetic float 1.3. The magnetic float 1.3 can be avoided from being assembled in the inner cavity of the liquid storage box 1.1. The magnetic float 1.3 and the valve seat 1.2 are installed outside first, without space restrictions, and are easier to install and operate, and convenient for production and assembly.

[0044] Furthermore, Figure 2As shown, a sealing ring 1.7 is provided at the connection between the rear cover 1.1.3 and the liquid box body 1.1.1. By providing a sealing ring 1.7 at the connection between the rear cover 1.1.3 and the liquid box body 1.1.1, detergent leakage can be prevented, thereby preventing the liquid delivery device from being damaged due to detergent leakage, which is beneficial to improving the electrical safety of the liquid delivery device.

[0045] Specifically, Figure 5 As shown, the fixed box body 4 includes a box body 4.1 and a box cover 4.2 covering the box body 4.1, the box cover 4.2 is arranged above the liquid storage box 1.1, and the magnetic sensor 2 is installed on the box cover 4.2, so that the magnetic sensor 2 is arranged above the liquid storage box 1.1. When the fixed box body 4 needs to be assembled, the parts of the box body 4.1 and the box cover 4.2 can be assembled separately first, and then the box cover 4.2 is covered on the box body 4.1, and the assembly of the fixed box body 4 can be completed, avoiding direct assembly in the fixed box body 4. The parts of the box body 4.1 and the box cover 4.2 are assembled separately, and the operation space is larger, which is convenient for assembling the parts inside the fixed box body 4.

[0046] Specifically, Figure 2 and Figure 4 As shown, when the magnetic float 1.3 is at the lowest position, the height of the upper end surface of the magnetic float 1.3 is lower than the height of the upper end surface of the valve seat 1.2, and the height of the lower end surface of the magnetic float 1.3 is higher than the height of the lower end surface of the valve seat 1.2. When the magnetic float 1.3 is at the lowest position, the height of the upper end surface of the magnetic float 1.3 is lower than the height of the upper end surface of the valve seat 1.2, and the height of the lower end surface of the magnetic float 1.3 is higher than the height of the lower end surface of the valve seat 1.2. The magnetic float 1.3 is between the upper end surface and the upper end surface of the valve seat 1.2. During assembly, the magnetic float 1.3 will not interfere with the opening when it is extended into the opening, which is convenient for the installation of the back cover 1.1.3.
