DETAILED DESCRIPTION OF THE EMBODIMENT

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application. In addition, the directional terms mentioned in the following embodiments, such as "upper", "lower", "left", "right", etc., are only with reference to the directions of the accompanying drawings. Therefore, the directional terms used are for illustration rather than to limit the present invention.

[0021] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0022] Embodiment: An intelligent detergent dispensing device that prevents leakage and liquid cross-flow. Refer to the attached Figure 1 - attached Figure 5 , including a water circuit component 3, a suspension component 5, and a liquid pumping pump 6. The water circuit component 3 is provided with a water inlet end and a water outlet end. The water inlet end and the water outlet end of the water circuit component 3 are respectively connected to tap water and a washing machine; the suspension component 5 is used to suspend the liquid storage bottle body 4. The mouth of the liquid storage bottle body 4 suspended on the suspension component 5 faces upward. A plurality of the liquid storage bottle bodies 4 are provided. The liquid stored in the liquid storage bottle body 4 includes but is not limited to detergent and sterilizing liquid; each liquid storage bottle body 4 corresponds to a liquid pumping pump 6. The liquid inlet end and the liquid outlet end of the liquid pumping pump 6 are respectively connected to the liquid storage bottle body 4 and the water circuit component 3 through pipelines.

[0023] Suspend the liquid storage bottle body 4 on the suspension component 5, and connect the liquid storage bottle body 4 and the water circuit component 3 through the liquid pumping pump 6. Only when the liquid dispensing work is carried out, the liquid in the liquid storage bottle body 4 is pumped into the water circuit component 3 through the liquid pumping pump 6. There is no need for deliberate sealing at other times, greatly reducing the risk of liquid leakage.

[0024] Specifically, the mouth of the liquid storage bottle body 4 suspended on the suspension component 5 faces upward and the height is lower than that of the water circuit component 3, so that the liquid in the liquid storage bottle body 4 is less likely to leak under normal conditions.

[0025] Specifically, the water circuit component 3 includes a main pipeline 31, a water inlet end pipeline 32, and a water outlet end pipeline 33.

[0026] Specifically, a one-way valve is provided in the water inlet end pipeline 32, and the one-way valve only allows water flow to enter the main pipeline 31 from the water inlet end pipeline 32.

[0027] By providing a one-way valve in the water inlet end pipeline 32, it is possible to prevent the water flow from flowing back into the tap water pipeline.

[0028] Specifically, a number of adapters 34 are connected to the main pipeline 31, and each adapter 34 corresponds to a liquid pumping pump 6. A check valve is arranged at the position where the adapter 34 is connected to the liquid inlet of the main pipeline 31, and the check valve only allows liquid to flow from the adapter 34 into the main pipeline 31.

[0029] By arranging a check valve at the position where the adapter 34 is connected to the liquid inlet of the main pipeline 31, it is possible to prevent water from flowing back into the liquid storage bottle body 4, causing liquid dilution or outflow.

[0030] Specifically, this embodiment further includes a control system and a solenoid valve 35. The solenoid valve 35 is arranged on the main pipeline 31 or the water inlet pipeline 32, and the control system is used to control the opening and closing of the solenoid valve 35.

[0031] When in use, the solenoid valve 35 can be set to the normally closed state. In this way, during non-liquid injection time, the water circuit assembly 3 is in the closed state. Even if the water supply pipeline of the tap water stops, it will not cause backflow due to negative pressure being transmitted into the water circuit assembly 3.

[0032] Specifically, a pressure sensor 36, and / or a flow meter 38, and / or a detector 37 are arranged on the main pipeline 31; the pressure sensor 36 is arranged behind the solenoid valve 35, and the detector 37 is used to detect the concentration of detergent in the clear water.

[0033] Through the arrangement of the pressure sensor 36 and the flow meter 38, during liquid injection, it is possible to monitor the water pressure and flow rate on the main pipeline 31 in real time. When liquid injection is in progress and the water supply pipeline of the tap water happens to stop, the reduction of the water pressure and flow rate in the main pipeline 31 can be immediately monitored through the pressure sensor 36 and the flow meter 38, so as to timely control the solenoid valve 35 to close through the control system, thereby preventing the liquid from flowing back into the tap water pipeline.

[0034] Since the resistance will change after detergent is injected into the clear water, the detector 37 can obtain the concentration of detergent in the water by detecting the resistance in the water, thereby being able to reflect whether the liquid in the liquid storage bottle body 4 is sufficient.

[0035] Specifically, the water inlet pipeline 32, the water outlet pipeline 33, and the adapter 34 are all connected to the main pipeline 31 through a double-seal ring structure. The double-seal ring structure includes an inner core and an outer sleeve. Two sealing grooves are arranged outside the inner core, and sealing rings are arranged in both sealing grooves to form a double-seal ring structure. An annular fixing groove is also arranged outside the inner core, and two round holes are arranged on the outer shell corresponding to the annular fixing groove. A metal pin shaft is inserted into the round holes and the fixing groove to realize the connection between the outer shell and the inner core.

[0036] Specifically, this embodiment further includes a housing. The water circuit assembly 3, the liquid pumping pump 6, and the suspension assembly 5 are arranged in the housing. When the liquid storage bottle body 4 is suspended on the suspension assembly 5, it is located at the bottom of the housing.

[0037] Specifically, the suspension assembly 5 includes a hanging bracket 51, a gravity sensor 52, and a fixed plug 53. A suspension groove for horizontally pushing the liquid storage bottle body 4 is provided on the hanging bracket 51. One end of the gravity sensor 52 is connected to the housing, and the other end is connected to the hanging bracket 51. The fixed plug 53 is detachably connected to the hanging bracket 51 to limit the liquid storage bottle body 4 pushed into the suspension groove.

[0038] Through the setting of the gravity sensor 52, the weight of the liquid storage bottle body 4 suspended on the hanging bracket 51 can be detected. By presetting a weight value, when the gravity sensor 52 detects that the weight of the liquid storage bottle body 4 is lower than the preset weight value, the control system reminds to add liquid in time through the background.

[0039] Through the setting of the gravity sensor 52, when an external person steals the liquid in the liquid storage bottle body 4 by pumping, the gravity sensor 52 can detect that the weight drops linearly in a short time. Based on the information detected by the gravity sensor 52, it is judged that there is an external person stealing the liquid stored in the liquid storage bottle body 4 at this time, and the control system issues an alarm through the background. When an external person steals the liquid storage bottle body 4 by violent pulling, the gravity sensor 52 detects that the weight increases sharply. Based on the information detected by the gravity sensor 52, it is judged that there is an external person stealing the liquid storage bottle body 4 by pulling at this time, and the control system issues an alarm through the background.

[0040] Specifically, the gravity sensor 52 and the hanging bracket 51 are connected together by screws or pins.

[0041] Specifically, the pipeline connected to the liquid extraction pump 6 is set as a flexible hose. A number of notches or grooves are provided in the middle and sides of the hanging bracket 51 to limit the flexible hose on the liquid extraction pump 6.

[0042] An insertion plate installation groove 511 for inserting the fixed plug 53 is provided on the hanging bracket 51. A fixing rib 54 is provided on the hanging bracket 51 near the insertion plate installation groove 511. A claw is provided on the insertion plate corresponding to the fixing bracket. When the fixed plug 53 is inserted into the insertion plate installation groove 511, the claw is clamped with the fixing rib 54.

[0043] Specifically, a bottle body installation groove 512 for inserting the liquid storage bottle body 4 is provided on the hanging bracket 51.

[0044] Specifically, the claw and the fixing rib 54 are set as a double-bevel structure to facilitate disassembly and assembly.

[0045] Specifically, a sensor installation groove 11 for inserting the gravity sensor 52 is provided in the housing, and a support frame 12 for supporting the gravity sensor 52 is provided at the bottom of the sensor installation groove 11.

[0046] Specifically, a positioning and mounting hole 13 is provided at a position in the housing adjacent to the sensor mounting groove 11. The positioning and mounting hole 13 is used to fix screws or pins to realize the connection between the gravity sensor 52 and the housing.

[0047] Specifically, the control system is set as several control boards.

[0048] Specifically, the housing is set as a rear housing 1 and a front cover 2. The waterway assembly 3, the suspension assembly 5, and the liquid extraction pump 6 are all arranged in the rear housing 1, and the front cover 2 is fixed on one side of the rear housing 1; several control boards of the control system are respectively arranged in the rear housing 1 and the front cover 2.

[0049] The principle of the present invention during use is as follows: The liquid storage bottle body 4 is suspended on the suspension assembly 5, and the connection between the liquid storage bottle body 4 and the waterway assembly 3 is realized through the liquid extraction pump 6. Only when the liquid injection work is carried out, the liquid in the liquid storage bottle body 4 is pumped into the waterway assembly 3 through the liquid extraction pump 6. At other times, there is no need to deliberately seal, greatly reducing the risk of liquid leakage.

[0050] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
