[0030] Example:

[0031] See also Figure 1 and Figure 2 This embodiment provides a bottle washing machine, including a first washing liquid bottle 1, a first circulation pipe 2, an ultrasonic cleaning machine 3, a second circulation pipe 4 and a second washing liquid bottle 5.

[0032] The reagent bottle 6 to be cleaned is placed in the ultrasonic cleaning machine 3, and a first liquid discharge port 33 is provided on the ultrasonic cleaning machine 3. Generally speaking, the first liquid discharge port 33 is located at the bottom of the ultrasonic cleaning machine 3 to allow the liquid in the ultrasonic cleaning machine 3 to be completely discharged from the first liquid discharge port 33.

[0033] The first washing liquid bottle 1 is provided with a first liquid exchange port 11, the ultrasonic cleaning machine 3 is provided with a second liquid exchange port 31, and both ends of the first circulation tube 2 are respectively connected to the first liquid exchange port 11 and the second liquid exchange port 31. The first washing liquid bottle 1 contains a first cleaning reagent, and the first cleaning reagent in the first washing liquid bottle 1 can flow into the ultrasonic cleaning machine 3 through the first liquid exchange port 11, the first circulation tube 2, and the second liquid exchange port 31 in sequence, so as to allow the ultrasonic cleaning machine 3 to clean the reagent bottle 6 with the first cleaning reagent.

[0034] The first flow tube 2 is provided with a first valve, which can control the on-off state of the first flow tube 2. When the ultrasonic cleaning machine 3 uses the first cleaning reagent to clean the reagent bottle 6, the first flow tube 2 needs to be kept disconnected.

[0035] The second washing liquid bottle 5 is provided with a third liquid exchange port 51, and the ultrasonic cleaning machine 3 is also provided with a fourth liquid exchange port 32. The two ends of the second circulation tube 4 are respectively connected to the third liquid exchange port 51 and the fourth liquid exchange port 32. The second cleaning reagent is contained in the second washing liquid bottle 5. It is worth noting that the first cleaning reagent and the second cleaning reagent are cleaning reagents of different types. The second cleaning reagent in the second washing liquid bottle 5 can flow into the ultrasonic cleaning machine 3 through the third liquid exchange port 51, the second circulation tube 4 and the fourth liquid exchange port 32 in sequence, so as to allow the ultrasonic cleaning machine 3 to clean the reagent bottle 6 with the second cleaning reagent.

[0036] The second flow tube 4 is provided with a second valve, which can control the on-off of the first flow tube 2. The second flow tube 4 needs to be kept disconnected during the process of the ultrasonic cleaning machine 3 cleaning the reagent bottle 6 with the second cleaning reagent.

[0037] The bottle washing machine of this embodiment can clean the reagent bottle 6 in a variety of different ways.

[0038] The first cleaning method: open the first valve and disconnect the second valve to allow the first cleaning reagent to flow into the ultrasonic cleaning machine 3. After the liquid level of the first cleaning reagent in the ultrasonic cleaning machine 3 is above the reagent bottle 6, disconnect the first valve. Then, the ultrasonic cleaning machine 3 uses the first cleaning reagent to ultrasonically clean the reagent bottle 6. After the cleaning is completed, the first cleaning reagent in the ultrasonic cleaning machine 3 flows back to the first washing liquid bottle 1, or the first cleaning reagent in the ultrasonic cleaning machine 3 is completely discharged through the first drain port 33, and then the reagent bottle 6 is taken out from the ultrasonic cleaning machine 3 and dried. In this cleaning method, the bottle washer only cleans the reagent bottle 6 with the first cleaning reagent.

[0039] The second cleaning method: open the second valve and disconnect the first valve to allow the second cleaning reagent to flow into the ultrasonic cleaning machine 3, disconnect the second valve after the liquid level of the second cleaning reagent in the ultrasonic cleaning machine 3 is above the reagent bottle 6, and then the ultrasonic cleaning machine 3 uses the second cleaning reagent to ultrasonically clean the reagent bottle 6, and after the cleaning is completed, the second cleaning reagent in the ultrasonic cleaning machine 3 is returned to the second washing liquid bottle 5, or the second cleaning reagent in the ultrasonic cleaning machine 3 is completely discharged through the first drain port 33, and then the reagent bottle 6 is taken out of the ultrasonic cleaning machine 3 and the reagent bottle 6 is dried. In this cleaning method, the bottle washer only cleans the reagent bottle 6 with the second cleaning reagent.

[0040] The third cleaning method: open the first valve and disconnect the second valve to allow the first cleaning reagent to flow into the ultrasonic cleaning machine 3, disconnect the first valve after the liquid level of the first cleaning reagent in the ultrasonic cleaning machine 3 is above the reagent bottle 6, and then the ultrasonic cleaning machine 3 uses the first cleaning reagent to ultrasonically clean the reagent bottle 6, and then the first cleaning reagent in the ultrasonic cleaning machine 3 is refluxed to the first washing liquid bottle 1, or the first cleaning reagent in the ultrasonic cleaning machine 3 is completely discharged through the first liquid discharge port 33, and then the second valve is opened to allow the second cleaning reagent to flow into the ultrasonic cleaning machine 3, disconnect the second valve after the liquid level of the second cleaning reagent in the ultrasonic cleaning machine 3 is above the reagent bottle 6, and the ultrasonic cleaning machine 3 begins to use the second cleaning reagent to perform secondary ultrasonic cleaning on the reagent bottle 6, and after the cleaning is completed, the second cleaning reagent in the ultrasonic cleaning machine 3 is refluxed to the second washing liquid bottle 5, or the second cleaning reagent in the ultrasonic cleaning machine 3 is completely discharged through the first liquid discharge port 33, and finally the reagent bottle 6 is taken out from the ultrasonic cleaning machine 3 and dried. In this cleaning method, the bottle washer first uses the first cleaning reagent and then uses the second cleaning reagent to clean the reagent bottle 6 twice.

[0041] The fourth cleaning method: disconnect the first valve and open the second valve to allow the second cleaning reagent to flow into the ultrasonic cleaning machine 3, disconnect the second valve after the liquid level of the second cleaning reagent in the ultrasonic cleaning machine 3 is above the reagent bottle 6, and then the ultrasonic cleaning machine 3 uses the second cleaning reagent to ultrasonically clean the reagent bottle 6, and then the second cleaning reagent in the ultrasonic cleaning machine 3 is refluxed to the second washing liquid bottle 5, or the second cleaning reagent in the ultrasonic cleaning machine 3 is completely discharged through the first liquid discharge port 33, and then the first valve is opened to allow the first cleaning reagent to flow into the ultrasonic cleaning machine 3, disconnect the first valve after the liquid level of the first cleaning reagent in the ultrasonic cleaning machine 3 is above the reagent bottle 6, and the ultrasonic cleaning machine 3 begins to use the first cleaning reagent to perform secondary ultrasonic cleaning on the reagent bottle 6, and after the cleaning is completed, the first cleaning reagent in the ultrasonic cleaning machine 3 is refluxed to the first washing liquid bottle 1, or the first cleaning reagent in the ultrasonic cleaning machine 3 is completely discharged through the first liquid discharge port 33, and finally the reagent bottle 6 is taken out from the ultrasonic cleaning machine 3 and dried. In this cleaning method, the bottle washer first uses the second cleaning reagent and then uses the first cleaning reagent to clean the reagent bottle 6 twice.

[0042] The fifth cleaning method: first open the first valve and disconnect the second valve to allow the first cleaning reagent to flow into the ultrasonic cleaning machine 3, and then disconnect the first valve and open the second valve to allow the second cleaning reagent to flow into the ultrasonic cleaning machine 3, so that the ultrasonic cleaning machine 3 contains a mixed liquid of the first cleaning reagent and the second cleaning reagent. When the liquid level of the mixed liquid is above the reagent bottle 6, the second valve is disconnected, and the ultrasonic cleaning machine 3 uses the mixed liquid of the first cleaning reagent and the second cleaning reagent to ultrasonically clean the reagent bottle 6, and finally discharges the mixed liquid from the ultrasonic cleaning machine 3 through the first liquid discharge port 33, and takes out the reagent bottle 6 and dries it. In this cleaning method, the bottle washer uses the mixed liquid of the first cleaning reagent and the second cleaning reagent to clean the reagent bottle 6 once, thereby improving the cleaning efficiency.

[0043] The sixth cleaning method: first open the second valve and disconnect the first valve to allow the second cleaning reagent to flow into the ultrasonic cleaning machine 3, and then disconnect the second valve and open the first valve to allow the first cleaning reagent to flow into the ultrasonic cleaning machine 3, thereby the ultrasonic cleaning machine 3 contains a mixed solution of the first cleaning reagent and the second cleaning reagent, and when the liquid level of the mixed solution is above the reagent bottle 6, disconnect the first valve, and the ultrasonic cleaning machine 3 uses the mixed solution of the first cleaning reagent and the second cleaning reagent to ultrasonically clean the reagent bottle 6, and finally discharge the mixed solution from the ultrasonic cleaning machine 3 through the first liquid discharge port 33, and take out the reagent bottle 6 and dry it. In this cleaning method, the bottle washer uses the mixed solution of the first cleaning reagent and the second cleaning reagent to clean the reagent bottle 6 once, thereby improving the cleaning efficiency.

[0044] The seventh cleaning method: open the first valve and the second valve at the same time, so that the first cleaning reagent and the second cleaning reagent flow into the ultrasonic cleaning machine 3 at the same time, so that the ultrasonic cleaning machine 3 contains a mixed liquid of the first cleaning reagent and the second cleaning reagent. When the liquid level of the mixed liquid is above the reagent bottle 6, disconnect the first valve and the second valve, and the ultrasonic cleaning machine 3 uses the mixed liquid of the first cleaning reagent and the second cleaning reagent to ultrasonically clean the reagent bottle 6, and finally discharge the mixed liquid from the ultrasonic cleaning machine 3 through the first liquid discharge port 33, take out the reagent bottle 6 and dry it. In this cleaning method, the bottle washer uses the mixed liquid of the first cleaning reagent and the second cleaning reagent to clean the reagent bottle 6 once, thereby improving the cleaning efficiency.

[0045] It should be noted that when using the fifth, sixth and seventh cleaning methods to clean the reagent bottle 6, the first valve and the second valve need to use one-way valves. At this time, the second valve prevents the first cleaning reagent from flowing into the second washing liquid bottle 5, and the first valve prevents the second cleaning reagent from flowing into the first washing liquid bottle 1.

[0046] When the reagent bottle 6 is cleaned using the first, second, third and fourth cleaning methods, at least one of the first circulation tube 2 and the second circulation tube 4 is provided with a circulation pump to allow the first cleaning reagent in the ultrasonic cleaning machine 3 to flow back to the first washing liquid bottle 1, and / or to allow the second cleaning reagent in the ultrasonic cleaning machine 3 to flow back to the second washing liquid bottle 5.

[0047] The above seven cleaning methods can be selected and implemented one by one, or several of them can be selected and implemented in combination, or several of them can be selected and repeated.

[0048] It can be seen that the bottle washing machine provided in this embodiment not only allows the first cleaning reagent or the second cleaning reagent to clean the reagent bottle 6 separately, but also allows the first cleaning reagent and the second cleaning reagent to clean the reagent bottle 6 simultaneously or successively. The cleaning methods are diverse and flexible, and can be selected according to actual needs.

[0049] In addition, the injection and discharge of the first cleaning reagent and / or the second cleaning reagent in the ultrasonic cleaning machine 3 can be achieved by coordinated control of the first valve, the second valve, the first drain port 33 and the circulation pump, which greatly reduces the manual workload and reduces the frequency of contact between the cleaning staff and the first cleaning reagent. It not only improves the cleaning efficiency of the reagent bottle 6, but also reduces the potential safety and health risks of the cleaning staff.

[0050] As a specific application scenario, the first cleaning reagent is selected from acid cleaning liquid, alkaline cleaning liquid or organic cleaning liquid, and the second cleaning reagent is pure water. Accordingly, the bottle washing machine of this embodiment only uses the third cleaning method to clean the reagent bottle 6. In this application scenario of cleaning the reagent bottle 6, the purity requirements of the acid cleaning liquid, alkaline cleaning liquid and organic cleaning liquid are not high, and the purity requirements of pure water are relatively high. Therefore, the first cleaning reagent can be recycled, and the second cleaning reagent cannot be recycled. Therefore, a circulation pump is provided on the first circulation pipe 2, and a circulation pump is not required on the second circulation pipe 4.

[0051] In addition, in order to prevent the water mixed with impurities in the ultrasonic cleaning machine 3 from flowing back to the second washing liquid bottle 5, the second valve is specially selected as a one-way valve. It can be seen that the second cleaning agent in the second washing liquid bottle 5 is consumed relatively quickly, so the second washing liquid bottle 5 is provided with a first liquid replenishing port 52, through which the pure water in the second washing liquid bottle 5 is replenished in time.

[0052] The first washing liquid bottle 1 is provided with a second liquid replenishing port 12 and a second liquid discharging port 13. When the purity of the first cleaning agent in the first washing liquid bottle 1 is too low, the first cleaning agent in the first washing liquid bottle 1 is discharged through the second liquid discharging port 13, and the first washing liquid bottle 1 is replenished with a high-purity first cleaning agent through the second liquid replenishing port 12.

[0053] Preferably, the heights of the first washing liquid bottle 1 and the second washing liquid bottle 5 are both higher than the height of the ultrasonic cleaning machine 3, so as to allow the liquid levels in the first washing liquid bottle 1 and the second washing liquid bottle 5 to be higher than the liquid level in the ultrasonic cleaning machine 3, whereby under the action of the potential energy difference, the first cleaning reagent and the second cleaning reagent in the first washing liquid bottle 1 and the second washing liquid bottle 5 can spontaneously flow into the ultrasonic cleaning machine 3, thereby reducing the energy consumption during the cleaning process of the reagent bottle 6.

[0054] On this basis, the first washing liquid bottle 1 is provided with a first liquid level observation window 14. The second washing liquid bottle 5 is provided with a second liquid level observation window 53, through which the liquid levels in the first washing liquid bottle 1 and the second washing liquid bottle 5 can be observed respectively.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
