[0030] Embodiment 1
[0031] like Figure 1 As shown, this embodiment provides an ultrasonic cleaning device 100, comprising:
[0032] A cleaning unit, the cleaning unit comprises a cleaning cavity 110 with a top opening for accommodating a cleaning medium and an ultrasonic transducer for generating ultrasonic waves, wherein the ultrasonic transducer is used to vibrate the cleaning medium to clean the sampling needle;
[0033] The cleaning chamber 110 includes a cleaning pool 112 and a waste liquid pool 111, wherein the waste liquid pool 111 is used to receive the liquid overflowing from the cleaning pool 112;
[0034] A waste liquid port 120 and a flushing unit 130 are disposed in the waste liquid pool 111 , and a liquid flow direction of the flushing unit 130 is toward the waste liquid port 120 .
[0035] Ultrasonic cleaning and ordinary cleaning are both commonly used cleaning methods for sampling needles. Ultrasonic cleaning has a strong cleaning force and is suitable for cleaning more stubborn dirt or for deep cleaning, but it takes a long time, while ordinary cleaning flushes the sampling needle with running water, has a weaker cleaning force, is suitable for weaker dirt, and takes a shorter time. Ultrasonic cleaning and ordinary cleaning are suitable for different cleaning scenarios. Using different cleaning methods for different cleaning scenarios is conducive to improving cleaning efficiency.
[0036] The ultrasonic cleaning device 100 of this embodiment is provided with a cleaning pool 112 and a waste liquid pool 111 with an opening at the top, respectively. Ultrasonic cleaning can be performed in the cleaning pool 112, and ordinary cleaning can be performed in the waste liquid pool 111. Specifically, the waste liquid pool 111 can be arranged around the cleaning pool 112, and the cleaning pool 112 can be placed in the waste liquid pool 111; or the waste liquid pool 111 can be partially connected to the cleaning pool 112. The liquid gushing out of the cleaning pool 112 flows into the waste liquid pool 111.
[0037] Ultrasonic cleaning is performed in the cleaning tank 112, and an ultrasonic transducer is usually arranged at the bottom of the cleaning tank 112. An ultrasonic transducer is a device that converts electromagnetic energy into mechanical energy (acoustic energy), and is usually made of piezoelectric ceramics or other magnetostrictive materials. The piezoelectric effect of the material converts the electrical signal into mechanical vibration. The ultrasonic transducer can be used for ultrasonic cleaning, and the cavitation effect, acceleration effect and straight-forward flow effect of the ultrasonic wave generated by the ultrasonic transducer in the liquid directly and indirectly act on the liquid and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the cleaning purpose.
[0038] When ultrasonic cleaning is performed, a cleaning medium is injected into the cleaning tank 112, the part of the sampling needle that needs to be cleaned is immersed in the cleaning medium, and the ultrasonic transducer is started. The ultrasonic transducer acts on the cleaning medium, and then the cleaning medium indirectly acts on the dirt, so that the dirt falls off the sampling needle. The cleaning medium is a liquid, which can be cleaning water (such as purified water, deionized water) or a cleaning liquid (a solution containing a cleaning agent).
[0039] A waste liquid port 120 and a flushing unit 130 are provided in the waste liquid pool 111. The flushing unit 130 is used to discharge flushing water, which is usually cleaning water, to perform ordinary cleaning on the sampling needle. The waste liquid port 120 is used to discharge the waste liquid in the waste liquid pool 111. The overflow liquid in the cleaning pool 112 can be discharged from the waste liquid port 120.
[0040] The liquid flow direction of the flushing unit 130 refers to the final flow direction of the liquid flowing out of the flushing unit 130. When the liquid flows out of the flushing unit 130, the water flow is toward the sampling needle to be flushed. Specifically, the liquid can flow out of the flushing unit 130 horizontally or obliquely. After flushing the sampling needle, the liquid flows to the waste liquid port 120, which is convenient for quickly discharging the waste water generated during the normal cleaning of the sampling needle.
[0041] Specifically, the waste liquid port 120 can be set at the bottom of the waste liquid pool 111, which is conducive to the discharge of waste liquid. During routine cleaning, the sampling needle is placed above the waste liquid port 120.
[0042] In this embodiment, ultrasonic cleaning is achieved by providing a cleaning pool 112 and an ultrasonic transducer, and ordinary cleaning is achieved by providing a waste liquid pool 111 and a flushing unit 130. The cleaning pool 112 and the waste liquid pool 111 are close to each other, which is conducive to planning the movement path of the sampling needle and reducing the moving time. In addition, the cleaning pool 112 and the waste liquid pool 111 can share a wastewater outlet, that is, a drainage system, which is conducive to reducing production costs.
[0043] Embodiment 2
[0044] Based on the first embodiment, the flushing unit 130 includes at least two flushing ports 131 evenly distributed around the waste liquid port 120 .
[0045] The flushing unit 130 includes at least two flushing ports 131, and the flushing ports 131 discharge cleaning water to perform regular cleaning on the sampling needle. If there is only one flushing port 131, the side of the sampling needle facing away from the flushing port 131 is blocked and is not easily flushed. At least two flushing ports 131 are provided, and are evenly distributed around the waste liquid port 120, so that the outer wall of the sampling needle can be evenly flushed, and there will be no dead corners that cannot be flushed.
[0046] Specifically, two flushing ports 131 may be provided, and the two flushing ports 131 are arranged opposite to each other. The side of the sampling needle facing away from one of the flushing ports 131 can be flushed by the cleaning water discharged from the other flushing port 131 .
[0047] Embodiment 3
[0048] Based on the first embodiment, the vertical distance between the lowest point of the flushing port 131 and the waste liquid port 120 is less than or equal to 15 mm.
[0049] Usually, the length of the cleaning section of the sampling needle is 8 to 12 mm, and the vertical distance from the lowest point of the flushing port 131 to the waste liquid port is less than or equal to 15 mm, which can better adapt to the cleaning distance of the sampling needle.
[0050] Embodiment 4
[0051] Based on the first embodiment, the diameter of the flushing port 131 is less than or equal to 4 mm.
[0052] The outer wall of the sampling needle is rinsed with the rinse water discharged from the rinse port 131 . The rinse water needs to have a relatively high flow rate so that the impact force of the rinse water can be used to remove dirt on the outer wall of the sampling needle.
[0053] The flushing unit 130 needs to be connected to the storage device of the flushing water, and the flushing water needs to be pumped from the storage device to the flushing unit 130 through a pressure pump, and then discharged through the flushing port 131. It can be seen from the flow formula that when the pumping pressure of the pressure pump is determined, the liquid flow rate is inversely proportional to the square of the pipe diameter. Therefore, it can be seen that the larger the diameter of the flushing port 131, the smaller the flow rate of the flushing water discharged from the flushing port 131.
[0054] Since the volume of the automatic equipment using the needle is relatively small, and generally the greater the pumping pressure of the pressure pump, the larger the volume of the pressure pump. In the case of a relatively small volume of the automatic equipment, the pressure pump installed in the automatic equipment cannot be a pressure pump that is too large. The diameter of the flushing port 131 is less than or equal to 4 mm to ensure that the liquid discharged from the flushing port 131 has a relatively large flow rate, thereby ensuring the flushing effect.
[0055] Embodiment 5
[0056] On the basis of the first embodiment, the cleaning device further includes a liquid inlet, which is connected to the cleaning pool 112 .
[0057] The cleaning tank 112 is used for ultrasonic cleaning, and ultrasonic cleaning requires that a cleaning medium be filled into the cleaning tank 112 . The liquid inlet is connected to the cleaning tank 112 to facilitate the introduction of the cleaning medium into the cleaning tank 112 .
[0058] Embodiment 6
[0059] Based on the first embodiment, the cleaning device also includes an upper cover covering the waste liquid pool 111 , on which a first needle entry port and a second needle entry port are arranged, the first needle entry port faces the cleaning pool 112 , and the second needle entry port is arranged corresponding to the waste liquid port 120 .
[0060] Since the waste liquid pool 111 is arranged around the cleaning pool 112, and the cleaning pool 112 is arranged inside the waste liquid pool 111, the upper cover covers the waste liquid pool 111 and the cleaning pool 112 at the same time. The upper cover is provided with a first needle-allowing opening facing the cleaning pool 112 and a second needle-allowing opening corresponding to the waste liquid opening 120, respectively, to allow two cleaning positions to which the sampling needle needs to move, so as to facilitate the insertion of the sampling needle.
[0061] When ultrasonic cleaning is performed, there will be a lot of noise and it is easy to cause the cleaning medium to splash. When performing conventional cleaning, although the noise is slightly less than that during ultrasonic cleaning, there is still the problem of splashing of cleaning water.
[0062] The upper cover covers the waste liquid pool 111 , which helps to reduce noise and prevent liquid from splashing outside the waste liquid pool 111 .
[0063] In one embodiment, the upper cover is made of PP material.
[0064] PP, also known as polypropylene, is a colorless, odorless, non-toxic, translucent solid substance and a thermoplastic resin with excellent performance. It has light weight, chemical resistance, heat resistance, electrical insulation, strong shaping ability and low production cost.
[0065] Embodiment 7
[0066] Based on the sixth embodiment, the upper cover is detachably connected to the waste liquid pool 111 .
[0067] It is convenient to remove the upper cover from the waste liquid tank 111 and inspect and repair the components of the ultrasonic cleaning device 100 .
[0068] Embodiment 8
[0069] Based on the sixth embodiment, the caliber of the first needle inlet is smaller than the caliber of the cleaning pool 112 .
[0070] The first needle entry port is used to avoid the sampling needle and prevent the sampling needle from being blocked when extending into the cleaning tank 112. Therefore, the diameter of the first needle entry port only needs to be larger than the diameter of the sampling needle, and the diameter of the first needle entry port is smaller than the diameter of the cleaning tank 112. The opening of the cleaning tank 112 can be partially blocked to avoid splashing of liquid in the cleaning tank 112 during ultrasonic cleaning.
[0071] Embodiment 9
[0072] This embodiment also provides an analyzer, comprising the ultrasonic cleaning device of any one of Embodiments 1 to 8.
[0073] Other implementations and beneficial effects of the analyzer of this embodiment are equivalent to the beneficial effects of the above-mentioned ultrasonic cleaning device 100, and will not be described in detail here.
[0074] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
