Description

Technical Field

[0001] The utility model relates to the technical field of liquid supply devices, in particular to an induction type liquid supply device with expiration and remaining amount reminder. Background Art

[0002] There are a wide variety of induction type fully automatic liquid supply devices on the market, and the product quality is uneven. However, their functions are relatively single, that is, they have the function of automatically sensing liquid output, and can only meet the need of using without contact. The induction type fully automatic liquid supply devices on the market do not have any detection and identification functions for the liquid output body. On the one hand, customers only know that they need to replace the liquid after the liquid output is finished, which greatly reduces the user experience; on the other hand, the liquid output by the device itself has a quality guarantee period, and users often forget the time of the quality guarantee period, resulting in the use of expired liquid output, thus posing a safety hazard to users. Content of the Utility Model

Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "front", "rear", "left", "right", "up", "down", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. The technical solutions in the embodiments of the present invention can be combined, and the technical features in the embodiments can also be combined to form a new technical solution.

[0025] The present invention provides the following technical solutions:

[0026] As shown in the attached Figure 1 Connected to the attached Figure 2 As shown, it is the hardware part of the present invention. Specifically: Inside the liquid outlet box 7, there are a liquid outlet pump 8 and a control circuit board 11. The outlet of the liquid outlet pump 8 is connected to a liquid outlet pipe 10, and the inlet of the liquid outlet pump 8 is connected to a liquid inlet pipe 9. At the same time, on one side of the liquid outlet box 7, a storage container limit cover 4 and a tensile sleeve 2 are fixedly arranged, and a storage container bayonet 5 is arranged on the storage container limit cover 4;

[0027] For the other end of the tensile sleeve 2, it is fixedly connected to one end of the tensile spring 3, and the other end of the tensile spring 3 is fixedly connected to the fixed frame 1. At the same time, the tensile sleeve 2 is slidably arranged on the fixed frame 1. From this, it can be seen that the tensile spring 3 is to provide a resilience force to press the container. Therefore, products with resilience force such as gas springs and elastic ropes can be used for equivalent substitution.

[0028] Of course, the cooperation between the stretching sleeve 2 and the stretching spring 3 mentioned above is mainly for fixing the container. This is just one of the fixing methods. It can also be replaced by installing a buckle on the fixing frame 1 to fix the container, or by using the method of bolts and nuts to cooperate in fixing the container, etc.

[0029] At the same time, it can be seen from the figure that the fixing frame 1 is L-shaped, and a liquid level sensor 6 is provided at the turning point of the fixing frame 1. The lower end of the L-shaped fixing can abut against the container, and the stretching spring 3 provides the required abutting force. At the same time, the fixing frame 1 here can also be designed into a U shape or other suitable shapes to ensure that the container can be abutted to form a fixing effect and facilitate stretching.

[0030] As attached Figure 3 shown, it is a software part module diagram inside the control circuit board 11 of the present utility model. Specifically, it includes a signal receiving module 12 connected to the liquid level sensor 6 and an external device (liquid outlet inductor, not shown in the figure). The signal receiving module 12 transmits the signal to the signal processing module 13 for processing. The signal processing module 13 respectively transmits the processed signal to the signal output module 14 and the timing module 15. The signal output module 14 and the liquid outlet pump 8 are also connected to a reminder device (such as a reminder lamp, a reminder screen, a reminder sound, etc.).

[0031] The working principle and process of the present utility model:

[0032] 1. After grasping the fixing frame 1 and pulling down the stretching sleeve 2 by a certain distance, the liquid storage container is snapped into the position of the storage container bayonet 5.

[0033] 2. Release the stretching sleeve 2. Under the action of the stretching spring 3, the stretching sleeve 2 automatically returns to its original position, making the liquid level sensor 6 closely adhere to the liquid storage container, and the fixing frame 1 below catches the liquid storage container, making the whole liquid storage container relatively stable. At the same time, it also fits better with the liquid level sensor 6, making the detection result more accurate.

[0034] 3. After the front end of the device (liquid outlet inductor) gives a signal to the control circuit board 11, the control circuit board 11 controls the liquid outlet pump 8 to work. The liquid in the liquid storage container enters through the liquid inlet pipe 9 of the liquid outlet pump 8 and works through the liquid outlet pump 8, and exits through the liquid outlet pipe 10 of the liquid outlet pump 8 for use at the front end of the device.

[0035] 4. When the liquid in the liquid storage container is lower than the induction area of the liquid level sensor 6, the liquid level sensor 6 gives a signal to the control circuit board 11, and the control circuit board 11 feeds back to the front-end device to remind the user to replace the new liquid storage container in time.

[0036] 5. When the signal of the liquid level sensor 6 is not triggered within the specified time, the timing module 15 is activated, transmits a signal to the signal output module 14, and the control circuit board 11 feeds back to the front-end device to remind the user to replace the new liquid storage device in time.

[0037] 6. Whether it is due to expiration or a small amount that causes replacement, after the liquid storage device is replaced and the liquid level sensor 6 gives a signal to the control circuit board 11, the signal processing module 13 resets the time in the timing module 15 and starts timing again.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
