Generally, the ultrasonic cleaning and disinfecting device may include a machine body 10, an ultrasonic cleaning system, a controller, a liquid inlet assembly, a liquid outlet assembly, a floating member 20, a micro switch 30, and the like.

In the present application, as shown in fig. 1 and 2, a body 10 is provided with a cleaning tank 11, and the cleaning tank 11 has a rim 111, the cleaning tank 11 being for accommodating a cleaning liquid and medical instruments to be cleaned and sterilized when the ultrasonic cleaning and sterilizing apparatus is actually used.

An ultrasonic cleaning system (not shown) is used to transmit ultrasonic waves to the cleaning liquid in the cleaning tank 11 when cleaning the medical instrument, thereby achieving sufficient and thorough cleaning of the medical instrument by the ultrasonic waves. It should be noted that, the ultrasonic cleaning of a medical apparatus belongs to a technology which is more conventional in the prior art, and this part is not improved based on the present application, so the specific structure and the working principle of the ultrasonic cleaning system can be referred to the content of the present application described in the patent literature cited in the background technology or the content of the present application disclosed in the literature in which a similar ultrasonic cleaning and sterilizing device is described in the prior art, and will not be described in detail herein.

The liquid inlet assembly is used for pumping cleaning liquid required for cleaning the medical equipment into the cleaning tank 11. In particular, the feed assembly may include a feed tube 40, a pumping device, and a feed valve. As shown in fig. 2 or 3, the liquid inlet pipe 40 is in communication with the cleaning tank 11, for example, the liquid inlet pipe 40 may be in communication with a side wall of the cleaning tank 11, a pumping device (not shown in the drawings) is connected to the liquid inlet pipe 40 to pump the cleaning liquid into the liquid inlet pipe 40 through the pumping device, for example, the pumping device may be a booster pump, a liquid inlet valve (not shown in the drawings) is connected to the liquid inlet pipe 40 to control the on-off of the liquid inlet pipe 40, and the pumping device and the liquid inlet valve may be simultaneously in communication connection with a controller (not shown in the drawings).

Thus, when the cleaning solution is required to be pumped into the cleaning tank 11, the controller controls the pumping device to start and open the liquid inlet valve, at this time, the cleaning solution enters the cleaning tank 11 through the liquid inlet pipe 40, and after the liquid level of the cleaning solution in the cleaning tank 11 reaches the target liquid level, the controller controls the pumping device to stop and close the liquid inlet valve, so as to prevent the cleaning solution from overflowing from the edge 111 of the cleaning tank 11.

The liquid discharging component is used for discharging the cleaning liquid in the cleaning tank 11 after the cleaning of the medical equipment is completed. In particular, the drain assembly may include a drain 50 and a drain valve. As shown in fig. 3, the drain pipe 50 is communicated with the bottom of the cleaning tank 11, a drain valve (not shown) is connected to the drain pipe 50 to control the on-off of the drain pipe 50, and the drain valve can be also connected to the controller in a communication manner. Thus, when it is necessary to drain the cleaning liquid in the cleaning tank 11, the controller controls the drain valve to be opened to drain the cleaning liquid in the cleaning tank 11 through the drain pipe 50.

On this basis, in order to make the ultrasonic cleaning and disinfecting device have better anti-overflow performance, in combination with the content shown in fig. 1 or fig. 2, the machine body 10 is further provided with an overflow groove 12 communicated with the cleaning tank 11, so that the cleaning liquid can enter the overflow groove 12 in the process of pumping the cleaning liquid. For example, the overflow tank 12 may be a groove structure provided at the side of the cleaning tank 11 and having an open top.

As shown in fig. 1 and 4, a float member 20 is provided in the overflow vessel 12, the float member 20 has a float surface 21 lower than the rim 111 of the cleaning vessel 11, and the float member 20 is configured to float upward when the level of the cleaning liquid in the overflow vessel 12 reaches the float surface 21. Specifically, during the process of pumping the cleaning liquid into the cleaning tank 11, the cleaning liquid in the cleaning tank 11 will be increased continuously, after the liquid level of the cleaning liquid in the cleaning tank 11 reaches the connection position between the cleaning tank 11 and the overflow tank 12, the cleaning liquid will enter the overflow tank 12, and as the cleaning liquid in the overflow tank 12 is increased continuously, when the liquid level of the cleaning liquid in the overflow tank 12 reaches the floating surface 21 of the floating member 20, the cleaning liquid will exert a buoyancy force to the floating member 20 greater than the gravity of the floating member 20 itself, at this time, the floating member 20 will float upward under the buoyancy force exerted by the cleaning liquid.

The micro-switch 30 is in linkage with the float member 20, and the micro-switch 30 is communicatively connected to the controller. Wherein, the micro-switch 30 is used for sending a water level early warning signal to the controller when the floating member 20 floats to the limit position. The above-mentioned limit position means: when the level of the cleaning liquid in the cleaning tank 11 and the overflow tank 12 reaches the target level required for cleaning the medical instrument, the float member 20 is located. It will be appreciated, therefore, that the limit position may be adjusted according to the actual situation and is not limited thereto.

In this way, in the stage of pumping the cleaning solution, after the floating member 20 floats to the limit position under the action of the buoyancy force exerted by the cleaning solution, the micro switch 30 can timely send a water level early warning signal to the controller, so that the controller can be utilized to timely control the pumping device to stop working and close the liquid inlet valve so as to stop pumping the cleaning solution into the cleaning tank 11, thereby avoiding the condition that the cleaning solution overflows from the edge 111 of the cleaning tank 11, and further realizing the overflow preventing function of the ultrasonic cleaning and sterilizing device.

Conversely, as the cleaning liquid in the overflow tank 12 is continuously reduced due to use, the buoyancy force exerted by the cleaning liquid on the float member 20 is reduced, and the float member 20 moves downward to the initial position by its own weight, thereby preparing for the next detection of the level of the cleaning liquid in the cleaning tank 11.

Therefore, the application realizes the anti-overflow function of the ultrasonic cleaning and disinfecting device by adopting the cooperation of the floating piece 20 and the micro switch 30, and compared with the anti-overflow function realized by adopting a pressure difference switch in the prior art, the application can more accurately control the liquid level of the cleaning liquid in the cleaning tank 11, is beneficial to improving the anti-overflow performance of the ultrasonic cleaning and disinfecting device, thereby improving the reliability of the ultrasonic cleaning and disinfecting device in actual use.

In some embodiments of the present application, the specific configuration of the isopipe 12 and float member 20 is further described in order to provide for a secure upward float of float member 20 within isopipe 12, as shown in FIG. 4.

Specifically, the overflow trough 12 has a bottom wall 121, and the bottom wall 121 of the overflow trough 12 is provided with an upwardly extending and hollow mounting portion 13. The float 20 may then comprise a float 22 and a connecting portion 23, wherein the float 22 is located on top of the mounting portion 13 and the float 22 is provided with a float chamber 24 which is open downwards, in which case the float chamber 24 communicates with the overflow trough 12 and the float chamber 24 has a top wall, i.e. the top wall acts as the float surface 21 of the float 20.

The connection part 23 is connected to the floating part 22, for example, the top end of the connection part 23 may extend into the floating chamber 24 and then be connected to the center of the inner top of the floating part 22, and the bottom end of the connection part 23 passes through the mounting part 13 and passes through the bottom wall 121 of the overflow trough 12, that is, the connection part 23 is located inside the mounting part 13. Thus, in combination with the foregoing, when the cleaning liquid in the cleaning tank 11 enters the overflow tank 12, a part of the cleaning liquid entering the overflow tank 12 enters the floating chamber 24, thereby applying buoyancy to the floating portion 22, so that the floating portion 22 can drive the connecting portion 23 to float upwards synchronously, and since a part of air is contained in the floating chamber 24, the floating portion 22 can be ensured to float upwards reliably. In this process, the mounting portion 13 can play a certain limiting guiding role on the connecting portion 23, so as to further improve the reliability when the floating portion 22 drives the connecting portion 23 to float upwards.

It will be appreciated that in practical implementation, the top of the floating portion 22 may be provided with a ventilation hole 25 communicating with the floating chamber 24, and the ventilation hole 25 is higher than the floating surface 21. Through the arrangement of the ventilation holes 25, the pressure between the floating chamber 24 and the external environment can be balanced, so that the siphon effect of the floating member 20 is avoided, and the reliability of the floating member 20 when floating under the buoyancy effect is improved.

To enable the linkage between the float 20 and the micro-switch 30 such that the micro-switch 30 can send a water level warning signal to the controller when the float 20 is floated to the extreme position, in some embodiments of the present application, in conjunction with what is shown in fig. 2, 4 and 5, the micro-switch 30 is disposed outside the isopipe 12, for example, the micro-switch 30 may be mounted on the outer wall of the isopipe 12 by a bracket.

Meanwhile, the ultrasonic cleaning and sterilizing apparatus may further include a connection member 60, the connection member 60 being connected to the connection portion 23 of the float member 20, and the connection member 60 being also located outside the overflow vessel 12. For example, the connecting member 60 may have a first end and a second end, and the first end of the connecting member 60 may have a groove structure, so that the connecting portion 23 of the floating member 20 can be received in the first end of the connecting member 60, and the second end of the connecting member 60 is provided with a trigger portion 61 aligned with the micro switch 30.

Thus, when the floating portion 22 of the floating member 20 floats under the buoyancy force exerted by the cleaning solution in the overflow trough 12, the floating portion 22 drives the connecting portion 23 to move upwards synchronously, and the connecting member 60 moves synchronously under the driving of the connecting portion 23, so that the triggering portion 61 of the connecting member 60 is continuously close to the micro switch 30. When the floating portion 22 of the float 20 floats to the limit position, the triggering portion 61 of the connection member 60 just contacts with the contact of the micro switch 30, thereby triggering the micro switch 30 to transmit a water level early warning signal to the controller.

It will be appreciated that in order to enhance the stability of the movement of the connector 60 by the connector 23, in some embodiments of the present application, the connector 60 may be slidably disposed outside of the isopipe 12. For example, as shown in fig. 5, a sliding groove 112 for sliding the connecting member 60 may be formed on the outer wall of the cleaning tank 11, and a portion of the connecting member 60 may be slidably disposed in the sliding groove 112 on the outer wall of the cleaning tank 11.

On the other hand, considering that the damage failure of the micro switch 30 is unavoidable when the ultrasonic cleaning and disinfecting apparatus is actually used, in this case, if the cleaning liquid is continuously pumped into the cleaning tank 11, the cleaning liquid may still overflow from the edge 111 of the cleaning tank 11. For this reason, in some embodiments of the present application, the anti-overflow performance of the ultrasonic cleaning and disinfecting device is further optimized.

Specifically, with continued reference to fig. 4, the top end of the mounting portion 13 may be set lower than the rim 111 of the cleaning tank 11, while the top end of the mounting portion 13 is also higher than the floating surface 21 when the floating member 20 is in the limit position, that is, when the floating member 20 floats to the limit position, the floating surface 21 of the floating member 20 is still lower than the plane in which the top end of the mounting portion 13 is located.

Meanwhile, an overflow channel 26 is formed between the outer wall of the connecting portion 23 and the inner wall of the mounting portion 13, specifically, the outer diameter of the connecting portion 23 is slightly smaller than the inner diameter of the mounting portion 13 so as to form a gap therebetween as the overflow channel 26, and at this time, the overflow channel 26 includes a liquid inlet 261 provided at the top end of the mounting portion 13, that is, the gap between the connecting portion 23 and the top end of the mounting portion 13 may serve as the liquid inlet 261 of the overflow channel 26.

Thus, in the process of pumping the cleaning solution to the cleaning tank 11, as the floating member 20 continuously floats upwards, when the floating member 20 floats to the limit position, the trigger portion 61 of the connecting member 60 will contact with the contact of the micro switch 30, on the basis, if the micro switch 30 is damaged and fails, the micro switch 30 will not send a water level early warning signal to the controller, the process of pumping the cleaning solution still continues, and the liquid level of the cleaning solution in the floating chamber 24 will further rise, and when the liquid level of the cleaning solution in the floating chamber 24 reaches the liquid inlet 261 (i.e. the top end of the mounting portion 13) of the overflow channel 26, the cleaning solution will enter the overflow channel 26 and be discharged, thereby realizing that even if the micro switch 30 is damaged and fails, the cleaning solution can still be effectively prevented from overflowing from the edge 111 of the cleaning tank 11, and further improving the overflow preventing performance of the ultrasonic cleaning and sterilizing device.

On this basis, in order to achieve collection and concentration of the cleaning liquid discharged from the overflow path 26, the cleaning liquid is prevented from splashing. In some embodiments of the present application, overflow channel 26 further includes a liquid outlet 262 opposite liquid inlet 261, wherein the gap between the bottom of overflow trough 12 and connecting portion 23 may serve as liquid outlet 262.

At this time, as shown in fig. 2 and 4, the ultrasonic cleaning and disinfecting apparatus may further include a buffer chamber 70, where the buffer chamber 70 is disposed outside the overflow tank 12, and the buffer chamber 70 has an inlet aligned with the liquid outlet 262. For example, a tank with an opening at the top may be provided on the outer wall of the cleaning tank 11, and the opening of the tank is aligned with the liquid outlet 262, so that the interior of the tank is taken as the buffer chamber 70, and the opening of the tank is taken as the inlet.

Meanwhile, the aforementioned drain assembly may further include a drain branch pipe 80, as shown in fig. 3, one end of the drain branch pipe 80 is connected to the drain pipe 50, and the other end of the drain branch pipe 80 is connected to the buffer chamber 70.

In this way, when the cleaning solution flows out from the liquid outlet 262 of the overflow channel 26, the cleaning solution directly enters the buffer cavity 70 through the inlet of the buffer cavity 70, so as to collect the cleaning solution discharged from the overflow channel 26, and then the cleaning solution in the buffer cavity 70 flows through the liquid discharge branch pipe 80 and the liquid discharge pipe 50 in sequence and is discharged, so that the spilled cleaning solution is concentrated.

Of course, in practical implementation, the treatment mode of the cleaning liquid discharged from the overflow path 26 is not limited to this, and for example, a circulation line (not shown) may be provided between the buffer chamber 70 and the liquid inlet pipe 40, and a circulation pump may be provided on the circulation line, so that the cleaning liquid in the buffer chamber 70 may be pumped into the liquid inlet pipe 40 and replenished into the cleaning tank 11 by the circulation pump as needed, thereby realizing the recycling of the cleaning liquid.

The above is only a preferred embodiment of the present application, and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
