Description

Technical Field

[0001] The utility model relates to the field of oral care instruments, in particular to an oral cleaning device. Background Art

[0002] As a common cleaning and care device, the oral cleaning device works by spraying the cleaning medium into the oral cavity at a certain pressure, and using the impact force of the water flow to achieve cleaning and care of the oral cavity, teeth, and interdental spaces. In the related art, in addition to a water storage tank for storing clean water, the oral cleaning device is also equipped with a liquid storage tank for storing other liquids (such as oral medicines), in order to form a mixed liquid by mixing clean water and other liquids in the water storage tank, and then use the mixed liquid to achieve cleaning and care functions such as sterilization and deodorization of the oral cavity.

[0003] In some oral cleaning devices equipped with a liquid storage tank, when a part of the liquid in the liquid storage tank is consumed, the air retained in the liquid storage tank will change in volume due to factors such as the temperature difference between day and night, thermal expansion and contraction, thereby causing a change in the pressure in the liquid storage tank; when the pressure in the liquid storage tank is greater than that outside, part of the liquid can easily leak through the vent of the liquid storage tank to the inside or outside of the device, which not only causes a waste of liquid, but also easily causes contamination and corrosion of the electronic components inside the device or the outside of the body.

[0044] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0045] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0046] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0047] See also Figures 1 to 7 An embodiment of the present application provides an oral cleaning device, such as a water flosser; the oral cleaning device includes a housing 10, a container assembly, a pipeline assembly, a pump assembly, a control assembly, and other functional components as needed.

[0048] In order to describe the oral cleaning device more clearly and in detail, the height direction of the oral cleaning device is defined herein based on the oral cleaning device so as to distinguish the relationship between the described objects; illustratively, when the oral cleaning device is in a naturally placed state, the height direction can be understood as a vertical direction or an up and down direction.

[0049] See also Figures 1 to 3 The casing 10 can be understood as a collection of related components that constitute the approximate outer contour structure of the oral cleaning device, and is mainly used as an installation carrier for functional components such as container components, pipeline components, pump liquid components, and control components; with the help of the casing 10, the oral cleaning device can be held, moved, operated, etc.

[0050] Please combine Figures 1 to 3 The control component can be understood as a collection of related devices such as circuit boards, batteries, display screens, control keys, indicator lights, etc.; the control component is arranged in the housing 10, and mainly plays the role of regulating pipelines for all or part of the functional components in the oral cleaning device to support the realization of various functions of the oral cleaning device (for example, supporting the power on and off of the oral cleaning device, switching of functional modes, etc.).

[0051] See also Figures 1 to 3 The pump liquid component is arranged on the housing 10, and mainly plays the role of pumping the cleaning liquid stored in the container component out of the oral cleaning device through the pipeline component; that is, driving the cleaning liquid to spray out of the oral cleaning device at a certain pressure, thereby achieving the role of cleaning and caring for the oral cavity.

[0052] In one embodiment, see Figures 1 to 3 The pump liquid component includes a first fluid pump 41 and a second fluid pump 42 arranged inside the housing 10; the first fluid pump 41 and the second fluid pump 42 are electrically connected to the control component, and the control component can be used to control the states of the first fluid pump 41 and the second fluid pump 42, for example, starting the first fluid pump 41 and the second fluid pump 42 simultaneously or selectively.

[0053] See also Figures 1 to 3The container assembly includes a second container 22 and a first container 21 for storing different cleaning liquids; for ease of distinction and description, the cleaning liquid stored in the first container 21 is defined as a first cleaning liquid, and the cleaning liquid stored in the second container 22 is defined as a second cleaning liquid; illustratively, the first cleaning liquid can be oral medicine, saline, mouthwash, etc., which has sterilization, deodorization, descaling or other functions, and the second cleaning liquid can be clean water.

[0054] The second container 22 and the first container 21 are both arranged in the casing 10; for example, the second container 22 or the first container 21 is installed inside or outside the casing 10 in a detachable manner; for another example, based on the structural configuration of the casing 20, the second container 22 or the first container 21 is formed inside the casing 20; all these will not be elaborated here.

[0055] See also Figures 1 to 7 The pipeline assembly includes a first infusion pipeline 31, a second infusion pipeline 32 and a ventilation pipeline 33 arranged inside the casing 20; wherein, one end of the first infusion pipeline 31 is connected to the second container 22, and the other end of the first infusion pipeline 31 is connected to the nozzle component 50, and the first infusion pipeline 31 is mainly used to guide the second cleaning liquid in the second container 22 to discharge from the second container 22.

[0056] The second infusion pipeline 32 is arranged between the first container 21 and the first infusion pipeline 31, and is mainly used to guide the first cleaning liquid in the first container 21 into the first infusion pipeline 31, so that the different cleaning liquids provided by the second container 22 and the first container 21 can be mixed to form a mixed liquid during the process of flowing through the first infusion pipeline 31.

[0057] More specifically, see Figure 1 and Figure 2 The first fluid pump 41 is arranged in the first infusion line 31, and the second fluid pump 42 is arranged in the second infusion line 32; the power provided by the second fluid pump 42 can transport the first cleaning liquid in the first container 21 to the first infusion line 31 through the second infusion line 32; the power provided by the first fluid pump 41 can pump the cleaning liquid in the first infusion line 31 (for example, the second cleaning liquid from the second container 22, or the mixed liquid formed in the first infusion line 31) at a certain pressure through the nozzle part 50 to clean and care for the oral cavity.

[0058] It is understandable that, by regulating and managing the first fluid pump 41 and the second fluid pump 42 through the control component, different cleaning liquids can be selected as needed to clean and care for the oral cavity. For example, when only the first fluid pump 41 is enabled, the clean water stored in the second container 22 can be used to complete the cleaning and care of the oral cavity; when the first fluid pump 41 and the second fluid pump 42 are enabled at the same time, the mixed liquid can be used as the flushing medium to complete the cleaning and care of the oral cavity. In this way, the practical functions of the oral cleaning device can be enriched, and different cleaning and care needs can be met.

[0059] The ventilation pipe 33 connects the interior of the first container 21 with the exterior of the first container 21 to maintain the balance of air pressure inside and outside the first container 21, so that the first cleaning liquid in the first container 21 can be smoothly discharged from the first container 21 under the action of the pump liquid component (specifically, the second fluid pump 42); one end of the ventilation pipe 33 is connected to the first container 21 at a non-highest position of the first container 21 in the height direction, and the other end of the ventilation pipe 33 can be connected to the internal space of the casing 10, and can also be connected to the outside of the casing 10 or the oral cleaning device.

[0060] The ventilation line 33 is configured such that the volume of the ventilation line 33 is always greater than the expansion amount of the air retained in the first container 21 under a preset temperature difference. In specific implementation, the volume of the ventilation line 33 can be ensured to be always greater than the expansion amount of the air retained in the first container 21 by extending the length of the ventilation line 33 or increasing the diameter of the ventilation line 33.

[0061] Exemplarily, the ventilation pipeline 33 may be configured as a pipeline structure that bends and extends in the length direction thereof, so as to increase the volume of the ventilation pipeline 33 by extending the length of the ventilation pipeline 33 .

[0062] Exemplarily, the diameter of the ventilation line 33 is set to be larger than the diameter of the second infusion line 32, such as the diameter of the ventilation line 33 is 0.5-2.0 times larger than the diameter of the second infusion line 32; thereby increasing the volume of the ventilation line 33 by increasing the diameter of the ventilation line 33.

[0063] It should be noted that "expansion" can be understood as the increase or change in air volume at the same location on the earth (such as Shenzhen, Guangdong, Jinan, Shandong, etc.) and when the temperature difference between day and night is less than or equal to 30°C; it cannot be understood as the increase or change in air volume at different locations (such as the equator and Mount Everest) and over a long time span (such as winter and summer).

[0064] On the one hand, since the volume of the ventilation pipe 33 is always larger than the expansion volume of the air retained in the first container 21, when a part of the cleaning liquid in the first container 21 is consumed, the air retained in the first container 21 changes in volume due to the temperature difference between day and night, thermal expansion and contraction, etc., causing the remaining cleaning liquid in the first container 21 to partially overflow or flow into the ventilation pipe 33. With the help of the ventilation pipe 33, this part of the cleaning liquid overflowing from the first container 21 can be accommodated, thereby effectively avoiding a series of problems caused by the cleaning liquid leaking to the inside or outside of the casing 10 through the ventilation pipe 33.

[0065] On the other hand, compared with some solutions in which a vent is provided at the highest position of the first container 21, by setting the volume of the ventilation duct 33 to be always larger than the expansion amount of the air retained in the first container 21, the ventilation duct 33 can be connected and arranged at a non-highest position of the first container 21 (for example, extending into the first container 21) to adapt to the structural structure of the housing 10 or the oral cleaning device, reduce the occupation of the ventilation duct 33 on the internal limited structural space of the housing 10 or the oral cleaning device, and create favorable conditions for enhancing the compactness of the structure of the oral cleaning device and more reasonably arranging the structure of other functional components.

[0066] In some embodiments, the second fluid pump 42 may also be omitted. For example, along the flow direction of the cleaning liquid in the first infusion line 31, the end of the second infusion line 32 away from the first container 21 is connected to the first infusion line 31 at a position upstream of the first fluid pump 41, so that the first fluid pump 42 can provide a mixed liquid with a certain pressure to the oral cavity.

[0067] For another example, one end of the second infusion line 32 away from the first container 21 is connected to the first infusion line 31 or the nozzle member 50 at a position downstream of the first fluid pump 41. The power provided by the first fluid pump 42 can generate a negative pressure adsorption effect at a position or area connected to the first infusion line 31 or the nozzle member 50 and close to the second infusion line 32, so that while the second cleaning liquid in the second container 22 is transported to the nozzle member 50, the first cleaning liquid in the first container 21 can be simultaneously drawn in, thereby mixing in the first infusion line 31 or the nozzle member 50 to form a mixed liquid, and finally the mixed liquid is pumped out from the nozzle member 50.

[0068] In some embodiments, the second container 22 may be omitted, and the second cleaning liquid (such as clean water) provided from the outside of the oral cleaning device may be directly received by means of the first infusion line 31; for example, before the oral cleaning device is used, the liquid inlet of the first infusion line 31 may be connected to a faucet or other liquid storage container so that the first infusion line 31 can receive and transport the second cleaning liquid.

[0069] It should be noted that the description of the "nozzle component 50" is introduced in this article only to clearly and in detail explain the structural structure, functional principle, etc. of the oral cleaning device. That is to say, the nozzle component 50 is not necessarily a component of the oral cleaning device; that is: in some embodiments, the nozzle component 50 may be a component of the oral cleaning device, which may be arranged on the housing component 10 in a detachable or non-detachable manner, and connected to the first infusion line 31; in other embodiments, the nozzle component 50 is a consumable used in conjunction with the oral cleaning device. By installing the nozzle component 50 on the housing component 10 and connecting it to the first infusion line 21, the oral cleaning device can be used for oral cleaning care.

[0070] For ease of distinction and description, the two opposite ends of the ventilation duct 33 in its length direction are defined below as the first end and the second end of the ventilation duct 33; wherein, the first end of the ventilation duct 33 refers to the end of the ventilation duct 33 that is close to and connected to the first container 21, and the second end of the ventilation duct 33 refers to the end of the ventilation duct 33 that is connected to the internal space of the casing 10 or the outside of the oral cleaning device.

[0071] In some embodiments, the second end of the ventilation pipe 33 can be fixed to the housing 10, the first container 21 or other structural parts to prevent the second end of the ventilation pipe 33 from shifting, deforming, etc., which may affect the ventilation effect of the ventilation pipe 33 or cause leakage of the cleaning liquid.

[0072] In one embodiment, see Figure 5 and Figure 7 In the height direction of the oral cleaning device, the position of the second end of the ventilation pipe 33 is higher than the position of the first end of the ventilation pipe 33; for example, the first end of the ventilation pipe 33 can be connected to the first container 21 at a non-highest liquid level position of the first container 21 (for example, the middle side, bottom, etc. of the first container 21 in the height direction), and the position of the second end of the ventilation pipe 33 in the height direction is flush with or higher than the highest liquid level position of the first container 21.

[0073] Therefore, by utilizing the structural feature that the second end of the ventilation pipe 33 is higher than the first end of the ventilation pipe 33, part of the gravitational potential energy can be overcome, so that the first cleaning liquid entering the ventilation pipe 33 is relatively small. On the basis that the volume of the ventilation pipe 33 is greater than the expansion amount of the air retained in the first container 21, the cleaning liquid can be effectively prevented from overflowing from the ventilation pipe 33 to the inside or outside of the casing 10.

[0074] In one embodiment, see Figure 7The first end of the ventilation pipe 33 is connected to the first container 21 at the bottom of the first container 21 in the height direction (for example, a ventilation hole structure is provided on the bottom side wall of the first container 21 for docking or plugging with the first end of the ventilation pipe 33), and the second end of the ventilation pipe 33 is flush with or higher than the highest liquid level position of the first container 21.

[0075] By connecting the first end of the ventilation pipe 33 to the bottom of the first container 21, the height space occupied by the ventilation pipe 33 inside the casing 10 can be effectively reduced, creating conditions for reducing the size of the casing 10 or the oral cleaning device in the height direction.

[0076] In one embodiment, see Figure 6 The first end of the ventilation pipe 33 extends into the interior of the first container 21 from the bottom of the first container 21 in the height direction, and the height at which the first end of the ventilation pipe 33 extends into the first container 21 is flush with or higher than the highest liquid level position of the first container 21.

[0077] At this time, according to the internal structural structure or spatial dimensions of the casing 10, the height position of the second end of the ventilation duct 33 can be set to be higher than the height position of the first end of the ventilation duct 33, or can be set to be lower than or flush with the height position of the first end of the ventilation duct 33 (for example, the second end of the ventilation duct 33 protrudes from the bottom side wall of the first container 21, or extends toward the lower side of the first container 21).

[0078] Therefore, the ventilation duct 33 can be arranged by utilizing the height space occupied by the first container 21 inside the casing 10, thereby effectively enhancing the structural integration of the first container 21 and the ventilation duct 33, which is beneficial to improving the structural compactness of the oral cleaning device and reducing the number of components of the oral cleaning device.

[0079] In one embodiment, see Figure 6 and Figure 7 The second infusion pipeline 32 extends into the interior of the first container 21 from the bottom of the first container 21 in the height direction, and the height at which the first end of the ventilation pipeline 33 extends into the first container 21 is higher than the height at which the second infusion pipeline 32 extends into the first container 21.

[0080] Therefore, by extending the second infusion line 32 and the ventilation line 33 into the interior of the first container 21, the stability of the structural connection between the first container 21 and the second infusion line 32 and the ventilation line 33 can be effectively enhanced; at the same time, due to the height difference between the first end of the second infusion line 32 and the ventilation line 33, it can be ensured that the first cleaning liquid in the first container 21 can smoothly enter the second infusion line 32.

[0081] In one embodiment, see Figure 6 and Figure 7 The pipeline assembly also includes a connector 34, which is arranged at the bottom of the first container 21, and the first end of the ventilation pipeline 33 and the end of the second infusion pipeline 32 close to and used for connecting to the first container 21 are integrated with the connector 34.

[0082] In specific implementation, the connector 34 can be fixedly arranged at a position of the housing 10 corresponding to the bottom of the first container 21 or fixedly arranged at the bottom of the first container 21 in a detachable or non-detachable manner; an air flow channel and a liquid flow channel are formed inside the connector 34; the first end of the ventilation pipeline 33 can be passed through the air flow channel and extend into the interior of the first container 21, and can also be connected to the interior of the first container 21 through the air flow channel; one end of the second infusion pipeline 32 used to communicate with the first container 21 can be passed through the liquid flow channel and extend into the interior of the first container 21, and can also be connected to the interior of the first container 21 through the liquid flow channel.

[0083] Based on this, the ventilation line 33 and the second infusion line 32 can be firmly fixed to the first container 21 using the connector 34, so that the ventilation line 33 and the second infusion line 32 remain connected to the first container 21; on the other hand, by integrating the second infusion line 32 and the ventilation line 32 on the connector 34, the first container 21, the ventilation line 33 and the second infusion line 32 can be easily and quickly assembled and disassembled.

[0084] It should be noted that the description of “the highest liquid level position of the first container 21 ” is introduced in this article, and the highest liquid level position can be understood as the position of the liquid level of the cleaning liquid in the height direction when a predetermined amount of cleaning liquid is stored in the first container 21 .

[0085] In one embodiment, see Figure 3 and Figure 4 The first container 21 and the nozzle member 50 are arranged side by side at the top of the housing member 10 in the height direction, and the second container 22 is arranged at the bottom of the housing member 10 in the height direction. Generally, the second container 22 is mainly used to store cleaning liquids with large consumption, such as clean water, while the first container 21 is mainly used to store cleaning liquids with relatively small consumption, such as oral medicine, and the capacity or volume of the second container 22 is often much larger than the capacity or volume of the first container 21.

[0086] Therefore, arranging the second container 22 at the bottom of the casing 10 can lower the center of gravity of the oral cleaning device, improve the stability of the placement of the oral cleaning device and the comfort of holding and using; arranging the first container 21 at the top of the casing 10 can facilitate the replacement of the first container 21 or the replenishment of cleaning liquid into the first container 21, and setting the nozzle part 50 at the top of the casing 10 can also be more ergonomically designed, thereby improving the user experience.

[0087] It should be noted that the position where the nozzle member 50 is connected to the first infusion line 31 can be at the top of the housing member 10, or at other suitable positions; it can be specifically determined by the structural connection form between the nozzle member 50 and the housing member 10, the contour shape of the nozzle member 50, or the overall structural shape of the oral cleaning device, and is not limited here.

[0088] In one embodiment, see Figure 3 The first container 21 is an independent container detachably arranged on the top of the casing 10, and an assembly bin 10a is arranged on the top of the casing 10. The first end of the second infusion pipeline 32 and the ventilation pipeline 33 for connecting the first container 21 is arranged in the assembly bin 10a (for example, the connector 34 is fixedly arranged on the bottom side wall of the assembly bin 10a); correspondingly, the first container 21 is provided with a liquid flow interface and an air flow interface for docking or plugging the second infusion pipeline 32 and the ventilation pipeline 33.

[0089] Therefore, by accommodating the first container 21 in the assembly bin 10a, a connection relationship can be quickly established between the first container 21 and the second infusion line 32 and the ventilation line 33; at the same time, by replacing the first container 21, the cleaning liquid such as oral medicine can be replaced or supplemented.

[0090] In some embodiments, the ventilation duct 33 may also be configured as an integrated structure with the first container 21 which adopts an independent container, that is, the ventilation duct 33 is fixed to the first container 21 in the form of being connected to the first container 21, or the ventilation duct 33 is naturally formed on the first container 21 by configuring the structure of the first container 21; when the first container 21 is installed in the assembly bin 10a, the ventilation duct 33 is connected to the inside or outside of the casing 10.

[0091] In another embodiment, see Figure 4 The first container 21 is a cavity structure formed in the casing 10. Specifically, a liquid storage tank with an opening is arranged on the top of the casing 10, and the second infusion pipeline 32 and the ventilation pipeline 33 are connected to the liquid storage tank or extend into the liquid storage tank; the first container 21 can be formed by covering the opening of the liquid storage tank with the help of the cover member 23; and by removing the cover member 23 or through the liquid injection port set in the cover member 23, the cleaning liquid can be added to the liquid storage tank or the first container 21.

[0092] In one embodiment, see Figure 3 A first chamber 10b and a second chamber 10c separated from each other are formed inside the casing 10, for example, the first chamber 10b is located below the second chamber 10c in the height direction; wherein the first fluid pump 41, the second fluid pump 42, the control assembly and other related electronic components are arranged in the first chamber 10b, and the second end of the ventilation pipe 33 is extended into the second chamber 10c.

[0093] Therefore, by extending the second end of the ventilation pipe 33 into the second chamber 10c arranged isolated from the electronic components, even if the cleaning liquid in the first container 21 leaks through the ventilation pipe 33, it will not enter the first chamber 10b, thereby effectively preventing the leaked cleaning liquid from affecting the electronic components in the oral cleaning device and enhancing the protection effect on the relevant electronic components.

[0094] In one embodiment, see Figure 1 The second fluid pump 42 includes a peristaltic pump connected to the second infusion pipeline 32; the end of the second infusion pipeline 32 away from the first container 21 or the end located downstream of the peristaltic pump can be connected to the first infusion pipeline 31 at a position located upstream of the first fluid pump 41 (see Figure 1 ), or it can be connected to the first infusion pipeline 31 at a position downstream of the first fluid pump 41 (please refer to Figure 2 As for the first fluid pump 41, the first fluid pump 41 can adopt a water pump that can provide high-pressure pulse pressure (for example, can provide 600KPa pulse pressure) to ensure that the cleaning liquid sprayed from the nozzle member 50 or the oral cleaning device has sufficient pressure to ensure the effect of oral cleaning care.

[0095] When the peristaltic pump is enabled, the peristaltic pump can pump the first cleaning liquid in the first container 21 into the first infusion line 31 via the second infusion line 32 to mix in the first infusion line 31 to form a mixed liquid; when the peristaltic pump stops, it can act as a valve to cut off or close the second infusion line 32, thereby preventing the first fluid pump 41 from pumping the cleaning liquid provided by the second container 22 into the first container 21 via the second infusion line 32.

[0096] The peristaltic pump can play the dual role of pumping liquid and valve, which can effectively reduce the number of configurations of pumping liquid components or functional components of the oral cleaning device, which is conducive to reducing the structural complexity of the oral cleaning device.

[0097] For some examples, see Figure 2The second fluid pump 42 may also include other devices with liquid delivery functions such as a plunger pump and a diaphragm pump; correspondingly, the pump liquid assembly also includes a one-way valve 43 electrically connected to the control assembly, and the one-way valve 43 can be arranged in the second infusion pipeline 32 and located downstream of the second fluid pump 42.

[0098] The second infusion pipeline 32 can be opened or closed by opening and closing the one-way valve 43, so as to cooperate with the second fluid pump 42 to control the cleaning liquid to enter the first infusion pipeline 31 from the second infusion pipeline 32 in one direction. For example, when the one-way valve 43 opens the second infusion pipeline 32, the second fluid pump 42 can be started to pump the first cleaning liquid in the first container 21 into the first infusion pipeline 31; when the one-way valve 43 cuts off the second infusion pipeline 32, the first fluid pump 41 can be prevented from pumping the second cleaning liquid provided by the second container 22 into the first container 21.

[0099] In one embodiment, see Figures 1 to 3 The pump assembly also includes a detection component 44, which is mainly used to provide information support for whether to start the second fluid pump 42 (or together with whether to open the one-way valve 43) to ensure that the second fluid pump 42 is started only when the second container 22 can provide clean liquid, thereby avoiding the situation where the second fluid pump 42 still pumps oral medicine after the clean water in the second container 22 is exhausted.

[0100] For example, see Figures 1 to 3 The detection component 44 can be a waterless sensor or a flow sensor, etc. The detection component 44 is arranged in the first infusion pipeline 31 (for example, located downstream of the first fluid pump 41 and close to the second container 22), and the detection component 44 can establish an electrical connection with the second fluid pump 42, the one-way valve 43, etc. through the control component.

[0101] The second fluid pump 42 (or together with the one-way valve 43) is configured to start or stop pumping the cleaning liquid provided by the first container 21 to the first infusion pipeline 31 in response to the detection information of the detection member 44. When the first fluid pump 41 is started, when the detection member 44 detects that the second cleaning liquid flows continuously or at a preset flow rate, the second fluid pump 42 can be activated in a timely manner according to this information to deliver oral medicine to the first infusion pipeline 31; otherwise, the first fluid pump 41 can be stopped, and the second fluid pump 42 can be stopped or not activated to avoid wasting oral medicine, etc., or to pump the oral medicine into the second container 22 in reverse.

[0102] Exemplarily, the detection element 44 may also be a current sensor, a voltage sensor, etc., and the detection element 44 is electrically connected to the first fluid pump 41 and the second fluid pump 42; the detection element 44 can detect and obtain the status information (such as current, voltage, etc.) of the first fluid pump 41, so as to judge whether the cleaning liquid in the second container 22 has been exhausted or whether the first infusion pipeline 31 is continuously and in a preset amount receiving the second cleaning liquid according to the status of the first fluid pump 41. In this way, the information detected by the detection element 44 can also be used as a condition for the second fluid pump 42 to start or stop the first infusion pipeline 31 from delivering the cleaning liquid.

[0103] It should be noted that Figures 1 to 3 The bold solid line with an arrow in the middle represents the first infusion line 31, the bold dashed line with an arrow represents the second infusion line 32, and the dot-dash line with an arrow represents the ventilation line 33. Figures 5 to 7 The dot-dash line in represents the highest liquid level position of the first container 21.

For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
