Description

Technical Field

[0001] This utility model relates to the field of washing machines, specifically a three-cartridge automatic liquid level detection wiring harness. Background Technology

[0002] While multi-cartridge designs offer users more diverse washing options in the design of automatic laundry detergent dispensing systems, some existing systems have limitations in cartridge management. Especially when it's necessary to pull out and refill a specific cartridge individually, these systems often lack convenient operation methods. Specifically, existing multi-cartridge automatic laundry detergent dispensing devices typically employ an integrated design, meaning all cartridges are fixed inside a frame or device and cannot be individually removed. When a user needs to add detergent to a particular cartridge, the entire device usually needs to be stopped, and then the cartridge needs to be unlocked and moved through complex procedures. This design is not only cumbersome to operate but also easily affects the normal use of other cartridges and may even adversely affect the stability of the entire system. Therefore, we propose a three-cartridge automatic dispensing level detection wiring harness. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a three-cartridge automatic liquid level detection harness, which solves the aforementioned problems.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a three-cartridge automatic liquid level detection harness, comprising a sealed box, wherein a through groove is provided on the sealed box extending through both sides, a laundry detergent cartridge is slidably installed in the through groove, a handle is fixedly connected to the end of the laundry detergent cartridge, support frames are fixedly connected to the inner walls of both sides of the through groove, a liquid level detection sensor is fixedly connected between the ends of the two sets, a liquid level detection harness is fixedly connected to the end of the liquid level detection sensor, a ventilation hole for dispensing laundry detergent is provided on the top of the sealed box, and further comprising:

[0005] The liquid scraping assembly, located within the through-channel, is used to scrape away the laundry detergent from the liquid level detection sensor head.

[0006] Preferably, the ventilation holes are provided in three sets, and the three sets of ventilation holes are respectively located directly above the through groove and are connected to the through groove.

[0007] Preferably, the inner walls on both sides of the three sets of through grooves are provided with side grooves, and the two sides of the laundry detergent ink cartridge are fixedly connected with protruding rods, and the two sets of protruding rods are slidably connected to the two sets of side grooves respectively.

[0008] Preferably, the wiper assembly includes a support plate, a return spring, mounting blocks, and a wiper ring. The support plate is fixedly connected to the top inner wall of the three sets of through slots, and the return spring is fixedly connected to the side of the support plate. Two sets of mounting blocks are fixedly provided on the inner wall of the laundry detergent cartridge, and a wiper ring is fixedly connected between the ends of the two sets of mounting blocks.

[0009] Preferably, one end of the return spring is fixedly connected to the side of the support plate, and the other end of the return spring is fixedly connected to the end of the laundry detergent cartridge.

[0010] Preferably, the end of the liquid level detection sensor extends slidably into the laundry detergent cartridge, and the scraper ring is slidably sleeved on the outer wall of the liquid level detection sensor.

[0011] Preferably, each of the three sets of through slots has a stop block fixedly connected to both sides of the reset spring, and one side of the stop block is attached to the end of the laundry detergent cartridge.

[0012] Compared with the prior art, this utility model provides a three-cartridge automatic liquid level detection harness, which has the following beneficial effects:

[0013] 1. This three-cartridge automatic liquid level detection harness, through its sliding installation structure, allows users to pull out any one of the laundry detergent cartridges individually for refilling. Refilling a single set of cartridges avoids the cumbersome steps of stopping the entire device and performing complex unlocking operations required in traditional integrated designs, greatly improving the convenience and efficiency of operation.

[0014] 2. The three-cartridge automatic liquid level detection harness and the scraper assembly solve the problem of laundry detergent residue. As the cartridge slides outward, the scraper ring can slide and engage with the outer wall of the liquid level detection sensor head, effectively scraping off residual laundry detergent, preventing the detergent from deteriorating and clogging the sensor head, thereby ensuring the stability and accuracy of the system.

[0015] 3. The three ink cartridge automatic dispensing level detection harness uses a sliding connection between the ink cartridge and the side groove via a protruding rod, as well as the elasticity of the return spring, to achieve stable sliding and resetting. This design not only ensures the stability of the ink cartridge during sliding, but also ensures that the ink cartridge can accurately and quickly return to its original position after being filled by the rebound force of the return spring.

[0041] Return spring 12: One end is fixedly connected to the support plate 11, and the other end is fixedly connected to the end of the laundry detergent ink cartridge 3. The design of the return spring 12 enables the ink cartridge to automatically return to its original position after being filled with ink using the spring's rebound force, improving the system's automation and convenience;

[0042] Stop block 13: Fixed within the through groove 2 on both sides corresponding to the return spring 12, used to limit the sliding range of the detergent ink cartridge 3. The design of stop block 13 ensures that the ink cartridge can accurately and quickly stop at the designated position when resetting, improving the stability and accuracy of the system;

[0043] Mounting block 14: Fixed to the inner wall of the laundry detergent cartridge 3, used to install the scraper ring 15. The design of the mounting block 14 takes into account the installation position and stability of the scraper ring 15, ensuring that the scraper ring can accurately scrape off the residual laundry detergent on the outer wall of the liquid level detection sensor head 6;

[0044] Scraper ring 15: Slidably sleeved on the outer wall of the liquid level detection sensor head 6, used to scrape off residual laundry detergent from the outer wall of the sensor head. The design and material selection of the scraper ring 15 ensure that it can efficiently scrape off residual laundry detergent, prevent the laundry detergent from deteriorating and clogging the sensor head, and improve the stability and reliability of the system.

[0045] Working principle: During use, the laundry detergent in the three sets of detergent cartridges 3 can be ventilated through the three sets of ventilation holes 4 to prevent the detergent from deteriorating. When the liquid level detection sensor 6 detects that the detergent in the detergent cartridge 3 is empty, the detergent cartridge 3 is pulled outward by the handle 10 on the sealed box 1, so that the detergent cartridge 3 slides in the two sets of side grooves 8 through the two sets of protruding rods 9. During the outward sliding process, the detergent cartridge 3 scrapes off the residual detergent on the outer wall of the liquid level detection sensor 6 through the scraper ring 15. At the same time, the pull of the detergent cartridge 3 deforms and lengthens the return spring 12. When the detergent cartridge 3 slides to the end position of the liquid level detection sensor 6, the detergent is added through the extended part of the detergent cartridge 3. After the detergent is added, the handle 10 is released, and the return force of the return spring 12 pulls the detergent cartridge 3 back. The detergent cartridge 3 stops when it touches the two sets of stop blocks 13 when it returns to the through groove 2.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
