DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-5 This application is described in further detail.
[0030] The present application discloses an automatic laundry detergent dispensing device. Figure 1 and Figure 2 The automatic laundry detergent dispensing device comprises a laundry detergent box 1, and the laundry detergent box 1 can be installed in a washing machine or outside the washing machine.
[0031] The liquid detergent box 1 is connected with a liquid inlet pipe 2 and a liquid outlet pipe 3. The liquid inlet pipe 2 is connected to the top of the liquid detergent box 1. A partition 4 is provided inside the liquid detergent box 1. A recessed portion 41 is provided on the partition 4. The bottom end of the recessed portion 41 is connected to a second liquid pump 5. The liquid outlet pipe 3 extends through the liquid detergent box 1, one end of which is connected to the second liquid pump 5, and the other end is connected to the washing machine. Therefore, the laundry detergent can flow into the second liquid pump 5 more smoothly through the recessed portion 41, and when the amount of the laundry detergent is small, the laundry detergent can be gathered.
[0032] When the washing liquid is added into the washing liquid box 1 through the liquid inlet pipe 2, the user can select different modes when starting to use the washing machine, and each mode uses a different amount of washing liquid. The second liquid extraction pump 5 extracts the washing liquid in the washing liquid box 1 into the washing machine.
[0033] Reference Figure 1 and Figure 3 In order to monitor the amount of laundry detergent in the laundry detergent box 1, a liquid level sensor 6 is provided in the laundry detergent box 1. The liquid level sensor 6 is connected to a controller 7 for sending a liquid level electrical signal to the controller 7.
[0034] The first liquid pump 8 is connected to the liquid inlet pipe 2, and the other end of the liquid inlet pipe 2 is inserted into the washing liquid barrel 19, and the bottom end contacts the bottom of the washing liquid barrel 19. A fixed cover 9 is sleeved on the liquid inlet pipe 2, and the fixed cover 9 is threadedly connected to the bottle mouth of the washing liquid barrel 19. A hole is set in the center of the fixed cover 9 for the liquid inlet pipe 2 to pass through, and the liquid inlet pipe 2 is not clamped with the hole. The fixed cover 9 can slide along the liquid inlet pipe 2 and adjust its position according to the height of the washing liquid barrel 19. In order to be able to fix the liquid inlet pipe 2 to various washing liquid barrels 19, the fixed cover 9 has different sizes, and the fixed cover 9 with the appropriate size can be selected according to the bottle mouth of the washing liquid barrel 19.
[0035] When the liquid level electrical signal received by the controller 7 reaches a first preset value, the amount of laundry detergent in the laundry detergent box 1 is small, and the controller 7 controls the first liquid pump 8 to start, and the laundry detergent is added to the laundry detergent box 1 through the liquid inlet pipe 2. When the liquid level electrical signal received by the controller 7 reaches a second preset value, the controller 7 controls the first liquid pump 8 to stop, and the laundry detergent box 1 is now full of laundry detergent.
[0036] In order to remind the user to replace the laundry liquid barrel 19, the device further includes a weighing platform 10, which is arranged outside the washing machine, and the laundry liquid barrel 19 is placed on the weighing platform 10, and the weighing platform 10 is used to weigh the weight of the laundry liquid barrel 19. The weighing platform 10 is connected to the controller 7 and sends a weight electrical signal to the controller 7. When the weight electrical signal received by the controller 7 reaches a third preset value, the laundry liquid in the laundry liquid barrel 19 is insufficient, and the user needs to replace a new laundry liquid barrel 19. The controller 7 is connected to an alarm 11 for issuing an alarm, prompting the user to replace the laundry liquid barrel 19.
[0037] The controller 7 is also connected to a communication module 12 for communicating with the server 13. The controller 7 sends the amount of laundry detergent and the remaining weight of the laundry detergent bucket 19 to the server 13 through the communication module 12. The server 13 is connected to the terminal 14. The user can log in to the server 13 through the terminal 14 to view relevant data.
[0038] In order to conveniently display the amount of laundry detergent in the laundry detergent box 1 to the user, the controller 7 is connected to a display screen 15 , and the display screen 15 displays the liquid level in the laundry detergent box 1 .
[0039] Furthermore, since the laundry detergent is relatively viscous, the laundry detergent may adhere to the inner wall of the laundry detergent box 1, so the amount of laundry detergent detected by the liquid level sensor 6 may be biased, affecting the accuracy of the detection.
[0040] Reference Figure 1 and Figure 4 A scraper 16 is provided on the inner wall of the liquid detergent box 1, and the scraper 16 is in contact with the inner walls of each surface of the liquid detergent box 1. A hollow connecting cylinder 17 is provided in the center of the liquid detergent box 1, and the top of the connecting cylinder 17 is fixed to the inner top surface of the liquid detergent box 1. The device also includes a driving assembly 18 for driving the scraper 16 to move up and down, and the driving assembly 18 includes a motor 181 fixed in the connecting cylinder 17, and a lead screw 182 is fixed to the output end of the motor 181, and the lead screw 182 is arranged in the vertical direction, and a slider 183 is slidably connected to the lead screw 182, and an annular magnet 184 is fixed to the outer wall of the slider 183.
[0041] A vertical slide groove 185 is provided on the inner wall of the connecting tube 17, and a protruding stopper 186 is provided on the annular magnet 184. The stopper 186 is inserted into the slide groove 185 and is slidably connected to the slide groove 185. A metal ring 187 is sleeved on the outer wall of the connecting tube 17, and the annular magnet 184 absorbs the metal ring 187 through the connecting tube 17. A plurality of connecting rods 188 are connected between the scraper 16 and the metal ring 187. When the motor 181 rotates, the slider 183 moves in the vertical direction along the lead screw 182, and then the annular magnet 184 drives the metal ring 187 to slide up and down along the connecting tube 17, and the scraper 16 can move from top to bottom.
[0042] Reference Figure 1 and Figure 5 The motor 181 is connected to the controller 7. When the liquid level electrical signal received by the controller 7 reaches a fourth preset value, the controller 7 controls the motor 181 to rotate forward, so that the scraper 16 scrapes off the laundry liquid attached to the inner wall of the laundry liquid box 1. Then the motor 181 rotates in the reverse direction, so that the scraper 16 returns to the top of the laundry liquid box 1.
[0043] Therefore, the liquid level sensor 6 detects more accurate data and can scrape the remaining laundry liquid for use. The fourth preset value is greater than the first preset value, that is, the operation is performed before the liquid level alarm. The lowest position to which the scraper 16 can slide is higher than the liquid level corresponding to the first preset value, and the scraper 16 does not contact the laundry liquid, thereby reducing the laundry liquid remaining on the scraper 16.
[0044] In order to improve the scraping effect, the side wall of the scraper 16 close to the bottom of the detergent box 1 is an arc surface that is inclined upward and concave inward in the direction away from the side wall of the detergent box 1. The side of the bottom edge of the scraper 16 close to the detergent box 1 is thinner, which is conducive to scraping off the detergent, and the arc surface is conducive to the detergent sliding down along the slope, reducing the residue on the scraper 16.
[0045] The implementation principle of an automatic laundry detergent dispensing device in an embodiment of the present application is as follows: when the controller 7 receives a liquid level electrical signal sent by the liquid level sensor 6 and the liquid level reaches a first preset value, the controller 7 controls the first liquid pump 8 to start, and the liquid inlet pipe 2 adds the laundry detergent in the laundry detergent barrel 19 into the laundry detergent box 1, and when the amount of laundry detergent in the laundry detergent barrel 19 decreases, the user is reminded, thereby realizing automatic replenishment of laundry detergent and reducing the possibility of users frequently adding liquid in a short period of time.
[0046] When the weighing platform 10 detects that the laundry detergent in the laundry detergent barrel 19 is low, the controller 7 controls the alarm 11 to sound an alarm, prompting the user to replace the laundry detergent barrel 19.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
