Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and more specifically, to a nasal care device. Background Art

[0002] A nasal care device is an electrical device that can spray fluid into the nasal cavity to clean and care for the nasal cavity or suck out liquid and other dirt in the nasal cavity. Usually, a suction device can be used to suck out the fluid in the nostrils or spray liquid for cleaning into the nasal cavity, thereby expelling the pathogens and dirt that have accumulated in the nasal cavity, restoring the nasal cavity to a normal physiological environment, restoring the self-detoxification function of the nasal cavity, and achieving the purpose of protecting the nasal cavity. Most of the current nasal care devices can only perform cleaning or suction functions respectively by replacing different care components. When the user replaces different care components, the nasal care device cannot automatically identify the type of currently installed care component to automatically switch the working mode, but requires the user to manually adjust it. On the one hand, it is inconvenient to use, and on the other hand, it may cause misoperation and affect the user's normal use of the nasal care device. Utility Model Content

[0003] The embodiment of the present application provides a nasal care device, which is at least used to solve the problem of inconvenience in using the nasal care device.

[0004] The nasal care device of the embodiment of the present application includes a host, at least two different types of care components and a circuit board assembly. The host includes a shell, a detection assembly and a pump body, and the pump body is located in the shell. The care components can be interchangeably installed on the shell, and the detection assembly is used to detect the type of the care components installed on the shell, and each type of the care components corresponds to a working state of the pump body and a working mode of the nasal care device. The circuit board assembly is electrically connected to the pump body and the detection assembly, respectively. When any type of the care components is installed on the nasal care device, the circuit board assembly controls the pump body to enter the corresponding working state so that the nasal care device is in the corresponding working mode.

[0005] When the nursing component is installed on the host, the detection component can detect the type of the currently installed nursing component, and control the pump body electrically connected to the circuit board component through the circuit board component to be in a working state that the currently installed nursing component can perform. At this time, the host can automatically identify the type of the nursing component and automatically switch to the corresponding working mode, which is more convenient to use.

[0006] In certain embodiments, the care component includes a nasal wash component, a nasal suction component and / or a drug delivery component. The nasal wash component corresponds to the pumping state of the pump body, and corresponds to the nasal wash mode of the nasal care device. The nasal suction component corresponds to the air suction state of the pump body, and corresponds to the nasal suction mode of the nasal care device. The drug delivery component corresponds to the drug pumping state of the pump body, and corresponds to the drug delivery mode of the nasal care device.

[0007] The nasal washing component, the nasal suction component and the medication component can be respectively installed on the main unit to correspond to the pump body. When the nasal washing component is installed on the main unit, the pump body can pump liquid into the nasal washing component so that the liquid used for cleaning can be sprayed out through the nasal washing component. When the nasal suction component is installed on the main unit, the pump body can extract the gas in the nasal suction component to reduce the internal air pressure of the nasal suction component, and the liquid in the nasal cavity can be sucked into the nasal suction component under the action of the air pressure difference.

[0008] In certain embodiments, the speed at which the pump body pumps liquid outward when in the liquid pumping state is greater than the speed at which the pump body sucks liquid inward when in the air suction state.

[0009] The pump body can quickly discharge liquid to clean the nasal cavity, and external air can quickly enter the pump body and the care component to balance the air pressure. The slow liquid suction speed can reduce the air pressure difference between the inside and outside of the care component, avoiding discomfort to the user during use.

[0010] In certain embodiments, the speed at which the pump body pumps liquid outward when in the liquid pumping state is greater than the speed at which the pump body pumps medicine outward when in the medicine pumping state.

[0011] The liquid discharged through the pump body and entering the nasal cavity can quickly clean the nasal cavity. Compared with the nasal wash mode, in the drug administration mode, the drug entering the nasal cavity needs to stay in the nasal cavity for a longer time to fully act in the nasal cavity, avoiding the drug from flowing out of the nasal cavity quickly and causing drug waste.

[0012] In certain embodiments, when the pump body is in a liquid pumping state, the flow rate of liquid pumped outward is greater than the flow rate of liquid sucked inward when the pump body is in an air suction state.

[0013] In the nasal wash mode, the pump body needs to pump a large amount of liquid into the nasal cavity to fully clean the nasal cavity. Since the flow rate of liquid or dirt in the nasal cavity is small, the flow rate of the pump body sucking liquid or dirt in the nasal suction mode can be smaller than the flow rate of the pump body pumping liquid in the nasal wash mode, so as to better meet the needs of users during use.

[0014] In certain embodiments, the flow rate of the pump body pumping liquid outward when the pump body is in the liquid pumping state is greater than the flow rate of the pump body pumping medicine outward when the pump body is in the medicine pumping state.

[0015] To improve the cleaning effect of the nasal cavity, in the nasal wash mode, the pump body can pump out more cleaning liquid to repeatedly wash the inside of the nasal cavity. In the drug administration mode, the amount of medicine that needs to be pumped into the nasal cavity is generally less than the amount of cleaning liquid required for repeated washing of the inside of the nasal cavity. Therefore, the flow rate of the pump body when pumping medicine will be less than the flow rate when washing the nose, so as to extend the continuous use time of the nasal care device as much as possible.

[0016] In certain embodiments, the pressure of the pump body sucking liquid inward when the pump body is in the air-inhaling state is greater than the pressure of the pump body pumping liquid outward when the pump body is in the liquid-pumping state.

[0017] In the nasal suction mode, the pump body can extract the gas in the care component, which is closer to a vacuum. Therefore, liquid and dirt deep in the nasal cavity can be sucked out, and the cleaning effect is better. When pumping liquid, the pressure of the pumped liquid is lower than the pressure of the suction liquid, which can reduce the impact of the liquid entering the nasal cavity on the inner wall of the nasal cavity and improve the comfort level during the use of the nasal care device.

[0018] In certain embodiments, the pressure of the pump body pumping liquid outward when the pump body is in the liquid pumping state is greater than the pressure of the pump body pumping medicine outward when the pump body is in the medicine pumping state.

[0019] To improve the cleaning effect of the nasal cavity, the liquid pumped out by the pump in the nasal wash mode can have a greater impact on the inside of the nasal cavity, and clean the nasal cavity more thoroughly than in the drug delivery mode. In the drug delivery mode, the pump only needs to pump the drug into the nasal cavity. Therefore, compared with the case where the pump pumps liquid outward, the pressure of the pump pumping the drug outward will be smaller, so that the drug can accurately reach the part of the nasal cavity that needs to be administered.

[0020] In some embodiments, the detection component includes a first detection member and a second detection member, one of which is disposed on the care component and the other is disposed on the housing. The first detection member and the second detection member cooperate to output detection data, and the detection data is used to reflect the type of the care component installed on the housing.

[0021] The first detection member and the second detection member are structures that can cooperate with each other to output detection data. One of the first detection member and the second detection member can be arranged on any care component that can be replaceably arranged on the host, and the other can be arranged on the host. When the care component is installed on the host, one of the first detection member and the second detection member arranged on the host can sense whether the other is arranged on the care component. When the two are inductively coupled, on the one hand, it can indicate that the care component is installed in place relative to the host, and on the other hand, it can also detect the type of care component currently installed, and output corresponding detection data to the circuit board assembly in the case of mutual induction to drive the pump body to be in different working states. The nasal care device can realize the function of automatically switching the working mode.

[0022] In certain embodiments, one of the first detection member and the second detection member disposed in the housing is electrically connected to the circuit board assembly, and the other one disposed in the care component is electrically insulated from the circuit board assembly.

[0023] One of the first detection member and the second detection member electrically connected to the pump body via the circuit board assembly can transmit a detection signal to the circuit board when sensing the other. Since the circuit board assembly is also electrically connected to the pump body, the circuit board assembly can control the pump body to be in different working states according to different detection signals. The other member provided in the care component can sense the one provided on the host without being electrically connected to the circuit board assembly. Therefore, there is no need to add electrically connected wires or power supply components on the care component, and the structure of the nasal care device is simpler.

[0024] In some embodiments, in the direction of the central axis of the nasal care device, the first detection member is disposed on a contact surface of the care component facing the bottom of the main unit, and the second detection member is disposed on a mating surface of the main unit closer to one end of the care component. When the care component is mounted on the main unit, the contact surface is opposite to the mating surface, so that the first detection member and the second detection member are directly opposite to each other in the direction of the central axis of the nasal care device.

[0025] When the contact surface and the mating surface are facing each other, the care component and the main unit can be installed along the same axis, and the two surfaces contacting each other can make the installation of the care component and the main unit more stable. In addition, when the first detection member and the second detection member are respectively arranged on the contact surface and the mating surface, the first detection member and the second detection member can also face each other when the care component is installed in place, and the induction between the two is more sensitive, and the detection data obtained is more accurate.

[0026] In some embodiments, the first detection member is clamped on the contact surface or the first detection member is glued to the contact surface.

[0027] In the case where the first detection member is located outside the care component and is disposed on a contact surface closer to the main unit, when the care component is installed in place, the distance between the first detection member and the second detection member disposed on the mating surface is closer, the sensing of the two is more sensitive, and misjudgment is less likely to occur. In addition, the first detection member disposed outside the care component is also convenient for disassembly and replacement when damaged.

[0028] In some embodiments, the pump body includes a flow channel opening, and the flow channel opening is arranged on the matching surface. When the care component is installed on the host, the pump body is connected to the care component through the flow channel opening.

[0029] The pump body is a bidirectional structure capable of spraying fluid outward or sucking gas inward, wherein the flow channel opening can be used to spray liquid or a mixed fluid formed by a mixture of gas and liquid. When a structure capable of spraying fluid outward, such as a nasal wash component, is installed on the host, the flow channel opening can be connected to the nursing component. When the nursing component is installed in place, the first detection component and the second detection component sense each other to determine the type of the nursing component, and the pump body can pump liquid into the nursing component or pump out a gas-liquid mixed fluid through the flow channel opening according to the detection data sent by the detection component.

[0030] In some embodiments, the care component is provided with a connecting portion, and the housing is provided with a matching portion. When the care component is installed on the host, the connecting portion cooperates with the matching portion to fix the relative position between the care component and the host.

[0031] The connecting part and the matching part are structures that can cooperate with each other. When the connecting part and the matching part cooperate with each other, the care component can be installed on the host, so that the care component is installed firmly in place relative to the host. The connecting part and the matching part can also locate the positions of the first detection part and the second detection part. When the connecting part and the matching part cooperate with each other, the first detection part can be directly opposite to the second detection part, the distance between the two is the shortest, and the sensing effect is better.

[0032] In some embodiments, when the first detection member is a magnetic member and the second detection member is a Hall sensor, the detection data includes magnetic field data detected by the second detection member. When the first detection member is a transmitter and the second detection member is a receiver, the detection data includes the strength or presence of a detection signal received by the second detection member.

[0033] The Hall sensor is a structure that can detect the magnetic field generated by the magnetic part. The Hall sensor can determine whether the care component is installed in place relative to the host according to the size of the magnetic field of the sensed first detection part. The Hall sensor can also determine the type of care component installed on the host at this time according to the presence or absence of the magnetic field of the sensed first detection part and / or the type of the magnetic field. The transmitter is a structure that can send a signal to the receiver, and the receiver can determine whether the first detection part and the second detection part are aligned according to the strength of the received detection signal and / or the presence or absence of the detection signal, thereby determining whether the care component and the host are installed in place. The receiver can also determine the type of care component currently installed on the host according to the type of the received signal.

[0034] In certain embodiments, the care component includes a nasal wash component and a nasal suction component, the second detection component is provided on the main unit, the first detection component includes two and is respectively provided on the nasal wash component and the nasal suction component, and the second detection component is used to cooperate with the two first detection components respectively so that the pump body enters a corresponding working state. In the case where the first detection component is a magnetic component and the second detection component is a Hall sensor, the magnetic field strength generated by the first detection component provided on the nasal wash component is different from the magnetic field strength generated by the first detection component provided on the nasal suction component and / or in the case where the first detection component is a magnetic component and the second detection component is a Hall sensor, the magnetic field direction of the first detection component provided on the nasal wash component toward the second detection component is different from the magnetic field direction of the first detection component provided on the nasal suction component toward the second detection component.

[0035] The first detection member may include multiple ones, each of which can be installed on a care component, and each of which can sense each other with the second detection member to send different detection data. In the case where the first detection member is a magnetic member, the magnetic field strengths of the multiple first detection members arranged on different care components are different or the magnetism of the multiple first detection members on the side facing the host is different. Therefore, when different care components are installed on the host, the second detection member can sense different magnetic field strengths and different magnetic field directions, and the second detection member can judge the type of care component currently installed on the host based on this, and control the pump body to be in different working states.

[0036] In some embodiments, the nursing component includes a nasal washing component and a nasal suction component, the first detection component is provided on the nasal washing component or the nasal suction component, the second detection component is provided on the host, and the first detection component is used to cooperate with the second detection component to enable the pump body to enter a corresponding working state. In the case where the first detection component is provided on the nasal washing component, when the nasal washing component is installed on the host, the second detection component is used to cooperate with the first detection component to drive the pump body to pump liquid through the circuit board component; when the nasal suction component is installed on the host, the second detection component is used to drive the pump body to inhale air through the circuit board assembly.

[0037] Only one of the nasal suction component and the nasal washing component can be provided with a first detection component. When the nasal suction component provided with the first detection component is installed on the host, the second detection component can receive or sense the signal or magnetic field, etc., emitted by the first detection component, and the second detection component can output detection data to control the pump body to extract the gas in the nasal suction component so that the nasal suction component can suck the liquid in the nasal cavity. When the nasal washing component without the first detection component is installed on the host, the second detection component cannot receive the signal or magnetic field, etc., and the second detection component can output detection data to control the pump body to spray fluid into the nasal washing component to clean the nasal cavity.

[0038] In some embodiments, the distance between the first detection member and the second detection member is less than or equal to 2 cm.

[0039] When the distance between the first detection member and the second detection member is greater than 2 cm, the distance between the first detection member and the second detection member is too far, and the attenuation and loss of the signal emitted by the first detection member or the magnetic field generated by the first detection member when reaching the second detection member are large. Therefore, the second detection member is likely to be unable to accurately sense the signal emitted by the first detection member or the magnetic field generated by the first detection member, resulting in an inability to identify the type of the care component. When the distance between the first detection member and the second detection member is less than or equal to 2 cm, the first detection member and the second detection member can be set close to each other, and the attenuation and loss of the signal emitted by the first detection member or the magnetic field generated by the first detection member when reaching the second detection member are smaller, and the induction between the first detection member and the second detection member is more accurate.

[0040] In some embodiments, the detection component is disposed on the shell or the care component. When the care component is installed on the shell, the detection component outputs detection data, and the detection data is used to reflect the type of the care component installed on the shell.

[0041] The detection component can be installed on the host or on the care component. When the detection component is installed on the care component, the detection component is first separated from the pump body and the circuit board assembly. When the care component is installed on the host, some structures on the host can contact the detection component to trigger the detection component. At this time, the detection component can be electrically connected to the pump body and the circuit board assembly through some structures on the host to transmit detection data to the circuit board assembly and control the pump body to be in different working states according to the detection data. When the detection component is installed on the host, the detection component can be directly electrically connected to the pump body and the circuit board assembly. When the care component is installed on the host, some structures on the care component can trigger the detection component so that the detection component transmits detection data to the circuit board assembly and controls the pump body to be in different working states according to the detection data.

[0042] In some embodiments, when the detection component is a contact sensor or a contact switch, the detection data includes trigger data output by the contact sensor or the contact switch. When the detection component is a pressure sensor, the detection data includes pressure data output by the pressure sensor. When the detection component is a signal transceiver sensor, the detection data includes the intensity of the detection signal received by the signal transceiver sensor.

[0043] The contact sensor and the contact switch are structures that can be triggered after contact. When the detection component is installed on the host and the care component is installed on the host, a partial structure on the care component can trigger the contact sensor and the contact switch so that the contact sensor and the contact switch can output trigger data. Another care component cannot trigger the contact sensor and the contact switch. At this time, the trigger data output by the contact sensor and the contact switch is different from the trigger data output when triggered, so that the pump body can switch different working modes according to different trigger data. The pressure sensor is a structure that can be triggered after sensing pressure. When the detection component is installed on the host and the care component is installed on the host, different care components can apply different pressures to the pressure sensor. The pressure sensor can output different pressure data according to the size of the pressure felt and the presence or absence, so that the pump body can switch different working modes according to different pressure data. The signal transceiver sensor is a structure that can autonomously send signals and receive reflected signals. When the detection component is installed on the host and the care component is installed on the host, different care components can reflect different signals to the signal transceiver sensor. The signal transceiver sensor can control the pump body to switch different working modes according to the intensity of the received reflected signal.

[0044] In some embodiments, at least one of the care components includes a trigger portion, and the trigger portion is disposed at the bottom of the care component facing the main unit; when the care component provided with the trigger portion is installed on the main unit, the trigger portion is used to cooperate with the detection component so that the detection component outputs a first signal to the circuit board assembly. When the care component not provided with the trigger portion is installed on the main unit, the detection component is used to output a second signal to the circuit board assembly, the first signal is different from the second signal, and the first signal and the second signal correspond to different working states of the pump body, respectively.

[0045] The trigger part is a structure that can trigger the detection component. When the trigger part is provided on the care component and the care component is installed on the host, the trigger part can cooperate with the detection component to make the detection component send a first signal. When the trigger part is not provided on the care component and the care component is installed on the host, the detection component can send a second signal. The first signal and the second signal can respectively drive the pump body to different working states through the circuit board assembly, so that the nasal care device can automatically switch the working mode of the nasal care device while switching the care component.

[0046] In some embodiments, the care component includes a care head and a liquid storage tank. The liquid storage tank includes a liquid storage chamber, the liquid storage chamber is used to store fluid, and the liquid storage chamber is connected to the pump body. The care head is detachably arranged on the top of the liquid storage tank, and the main unit is arranged at the bottom of the liquid storage tank.

[0047] The care component is a structure capable of caring for the nasal cavity, and the care head can directly contact the inside of the nasal cavity to allow liquid to flow into the liquid storage cavity or to allow fluid to flow from the care head to the inside of the nasal cavity. The liquid storage cavity is a structure for storing liquid, and the liquid storage cavity can store both clean cleaning liquid and waste liquid flowing out of the nasal cavity. Depending on the type of care component, the structure of the care head and the structure of the liquid storage tank are also different.

[0048] In some embodiments, the pump body includes a flow channel port and an air suction port, the flow channel port is used to allow fluid to flow, and the air suction port is used to suck gas. The liquid storage tank is provided with an inlet and an outlet, the inlet is communicated with the air suction port, the outlet is communicated with the care head, or the inlet is communicated with the flow channel port, and the outlet is communicated with the care head.

[0049] When the care component is installed on the main unit, the liquid storage cavity can be connected to the pump body to allow gas to enter the pump body or allow fluid to enter the liquid storage cavity. When the care component is a nasal suction component, the outlet of the liquid storage tank is used to allow liquid in the nasal cavity to flow into the liquid storage cavity, and the inlet of the liquid storage tank is used to communicate with the suction port of the pump body so that the gas in the liquid storage cavity can be extracted. When the care component is a nasal washing component, the inlet of the liquid storage tank is used to communicate with the flow channel port so that liquid can enter the liquid storage cavity, and the outlet of the liquid storage tank is used to communicate with the nasal cavity through the care head to spray the fluid pumped out by the pump body outward.

[0066] See also Figure 1 and Figure 2The nasal care device 100 of the present application includes a host 10, at least two different types of care components 30 and a circuit board assembly 50. The host 10 includes a shell 11, a detection assembly 13 and a pump body 15, and the pump body 15 is located in the shell 11. The care components 30 can be interchangeably installed on the shell 11, and the detection assembly 13 is used to detect the type of care components 30 installed on the shell 11. Each type of care component 30 corresponds to a working state of the pump body 15 and a working mode of the nasal care device 100. The circuit board assembly 50 is electrically connected to the pump body 15 and the detection assembly 13, respectively. When any type of care component 30 is installed on the nasal care device 100, the circuit board assembly 50 controls the pump body 15 to enter the corresponding working state so that the nasal care device 100 is in the corresponding working mode.

[0067] In the nasal care device 100 of the present application, when the care component 30 is installed on the host 10, the detection component 13 can detect the type of the currently installed care component 30, and control the pump body 15 electrically connected to the circuit board component 50 through the circuit board component 50 to be in a working state that the currently installed care component 30 can perform. At this time, the host 10 can automatically identify the type of the care component 30 and automatically switch to the corresponding working mode, which is more convenient to use.

[0068] The nasal care device 100 is further described below with reference to the accompanying drawings.

[0069] See also Figure 1 and Figure 2 In some embodiments, the host 10 is roughly an electrical component that can install the care component 30 and can realize multiple functions. The care component 30 includes a top 301 and a bottom 303 facing each other, the top 301 of the care component 30 is a free end, and the bottom 303 of the care component 30 is connected to the host 10. The host 10 can identify the type of the care component 30 installed on the host 10, and is in different working states according to the type of the care component 30 to achieve different working modes. The nasal care device 100 has a central axis A, and the central axis A of the nasal care device 100 at least passes through at least two of the three-dimensional geometric center of the care component 30, the three-dimensional geometric center of the host 10, the geometric center of the cross section of the top 301 of the care component 30, the geometric center of the cross section of the bottom 303 of the care component 30, and the geometric center of the cross section of the top of the host 10, and the central axis A of the nasal care device 100 is at least perpendicular to the bottom 303 of the care component 30 and / or the top of the host 10. The extension direction of the central axis A of the nasal care device 100 can be either the direction from the care component 30 to the host 10 or the direction from the host 10 to the care component 30, which is not limited here.

[0070] Specifically, in some embodiments, the shell 11 is a cylindrical structure with one end closed, and the detection component 13 and the pump body 15 can be arranged in the shell 11. When the care component 30 is installed on the host 10, in some embodiments, the care component 30 can cooperate with the shell 11 to be installed on the shell 11 and connected to the pump body 15 accordingly. In other embodiments, the care component 30 can cooperate with the shell 11 and the pump body 15 respectively to be installed on the shell 11 and the pump body 15 at the same time. The material of the shell 11 includes but is not limited to plastic, metal or rubber. The outer contour shape of the cross section of the shell 11 can be the same as the inner contour shape of the cross section of the shell 11, or it can be different, and there is no restriction here. The outer contour size of the cross section of the shell 11 is the same as the outer contour size of the cross section of the side where the care component 30 is connected to the shell 11, so that the connection between the shell 11 and the care component 30 is smoothly connected, and there is no height difference, so that there is no obvious bulge in the appearance of the nasal care device 100. The inner contour dimension of the cross section of the housing 11 is at least larger than the outer contour dimension of the largest cross section of the pump body 15 , so that the pump body 15 can extend into the housing 11 and be installed on the housing 11 .

[0071] More specifically, in some embodiments, the detection component 13 is a structure capable of detecting whether the care component 30 and the host 10 are installed in place and what type of care component 30 installed on the host 10 is. Figure 3 and Figure 4 The detection component 13 is disposed in one of the housing 11 or the care component 30. The detection component 13 can be installed in the host 10 or the care component 30. When different care components 30 are installed in the housing 11, the detection component 13 can output different detection data, and the different detection data can be used to reflect the type of care component 30 installed on the housing 11. In other embodiments, please combine Figure 7 and Figure 8 The detection component 13 includes two parts which can be respectively arranged on the housing 11 and the care component 30. The detection component 13 arranged on the housing 11 can be electrically connected to the circuit board component 50. The types of the detection components 13 installed on different care components 30 are different. When different care components 30 are installed on the housing 11, the detection component 13 arranged on the housing 11 can detect different care components 30 to output different detection data. The different detection data can be used to reflect the type of care components 30 installed on the housing 11.

[0072] Furthermore, please combine Figures 2 to 4In some embodiments, the detection component 13 is installed on the nursing component 30. At this time, the detection component 13 installed on the nursing component 30 is first separated from the pump body 15 and the circuit board assembly 50. When the nursing component 30 is installed on the host 10, a part of the structure on the host 10 can contact the detection component 13 to trigger the detection component 13. At this time, the detection component 13 can be electrically connected to the pump body 15 and the circuit board assembly 50 through the part of the structure on the host 10, so as to transmit the detection data to the circuit board assembly 50 and control the pump body 15 to be in different working states according to the detection data. In other embodiments, the detection component 13 is installed on the host 10. At this time, the detection component 13 can be directly electrically connected to the pump body 15 and the circuit board assembly 50. When the nursing component 30 is installed on the host 10, a part of the structure on the nursing component 30 can trigger the detection component 13, so that the detection component 13 transmits the detection data to the circuit board assembly 50 and controls the pump body 15 to be in different working states according to the detection data.

[0073] Furthermore, in some embodiments, the type of the detection component 13 includes, but is not limited to, a contact sensor, a contact switch, a pressure sensor, or a signal transceiver sensor. The contact sensor and the contact switch are structures that can be triggered after contact. When the detection component 13 is a contact sensor or a contact switch, the detection data includes trigger data output by the contact sensor or the contact switch. When the detection component 13 is installed on the host 10 and the care component 30 is installed on the host 10, a partial structure on the care component 30 can trigger the contact sensor and the contact switch so that the contact sensor and the contact switch can output trigger data. Another care component 30 cannot trigger the contact sensor and the contact switch. At this time, the trigger data output by the contact sensor and the contact switch is different from the trigger data output when triggered, so that the pump body 15 can switch different working modes according to different trigger data.

[0074] The pressure sensor is a structure that can be triggered after sensing pressure. When the detection component 13 is a pressure sensor, the detection data includes pressure data output by the pressure sensor. When the detection component 13 is installed on the host 10, and the care component 30 is installed on the host 10, different care components 30 can apply different pressures to the pressure sensor. The pressure sensor can output different pressure data according to the size and presence of the pressure it senses, so that the pump body 15 can switch to different working modes according to different pressure data.

[0075] The signal transceiver sensor is a structure that can autonomously send out signals and receive reflected signals. In the case where the detection component 13 is a signal transceiver sensor, the detection data includes the strength of the detection signal received by the signal transceiver sensor. In the case where the detection component 13 is installed on the host 10, and the care component 30 is installed on the host 10, different care components 30 can reflect different signals to the signal transceiver sensor, and the signal transceiver sensor can control the pump body 15 to switch to different working modes according to the strength of the received reflected signal.

[0076] Furthermore, in some embodiments, at least one care component 30 includes a trigger portion 309, which is a structure capable of triggering the detection component 13, and the trigger portion 309 is disposed at the bottom of the care component 30 facing the host 10. When the care component 30 provided with the trigger portion 309 is installed on the host 10, the trigger portion 309 is used to cooperate with the detection component 13 so that the detection component 13 outputs a first signal to the circuit board assembly 50. When the care component 30 not provided with the trigger portion 309 is installed on the host 10, the detection component 13 is used to output a second signal to the circuit board assembly 50, the first signal is different from the second signal, and the first signal and the second signal correspond to different working states of the pump body 15 respectively. The first signal and the second signal can drive the pump body 15 through the circuit board assembly 50 respectively, so that the pump body 15 is in different working states, and therefore, the nasal care device 100 can automatically switch the working mode of the nasal care device 100 while switching the care component 30.

[0077] See also Figure 7 and Figure 8 , and combined with Figure 6In some embodiments, the detection component 13 includes a first detection member 131 and a second detection member 133, the first detection member 131 and the second detection member 133 are structures that can cooperate with each other to output detection data, one of the first detection member 131 and the second detection member 133 is arranged on the care component 30, and the other is arranged on the housing 11. The care component 30 can be replaceably arranged on the host 10, and the first detection member 131 and the second detection member 133 cooperate to output detection data, and the detection data is used to reflect the type of the care component 30 installed on the housing 11. In the case where the care component 30 is installed on the host 10, one of the first detection member 131 and the second detection member 133 arranged on the host 10 can sense whether the other is arranged on the care component 30. In the case of mutual induction between the two, on the one hand, it can be explained that the care component 30 is installed in place relative to the host 10, and on the other hand, it can also detect the type of the currently installed care component 30, and output the corresponding detection data to the circuit board assembly 50 in the case of mutual induction, so as to drive the pump body 15 to be in different working states, and the nasal care device 100 can realize the function of automatically switching the working mode. For example, when the first detection member 131 is provided on the care component 30 and the second detection member 133 is provided on the housing 11, the second detection member 133 can cooperate with the first detection members 131 on different care components 30 to output different detection data. When the second detection member 133 is provided on the care component 30 and the first detection member 131 is provided on the housing 11, the first detection member 131 can cooperate with the second detection members 133 on different care components 30 to output different detection data.

[0078] Further, in some embodiments, the first detection member 131 and the second detection member 133 are both electrically connected to the circuit board assembly 50. In other embodiments, one of the first detection member 131 and the second detection member 133 disposed on the housing 11 is electrically connected to the circuit board assembly 50, and the other disposed on the care component 30 is electrically insulated from the circuit board assembly 50. One of the first detection member 131 and the second detection member 133 electrically connected to the pump body 15 via the circuit board assembly 50 can transmit a detection signal to the circuit board when sensing the other. Since the circuit board assembly 50 and the pump body 15 are also electrically connected, the circuit board assembly 50 can control the pump body 15 to be in different working states according to the different detection signals. The other disposed on the care component 30 can sense each other with the one disposed on the host 10 without being electrically connected to the circuit board assembly 50, so there is no need to add electrically connected wires or power supplies and other components on the care component 30, and the structure of the nasal care device 100 is simpler.

[0079] Specifically, in some embodiments, in the direction of the central axis A of the nasal care device 100, the care component 30 is provided with a contact surface 305 at the bottom facing the main body 10, the first detection member 131 is provided on the contact surface 305 and is located outside the care component 30, the end of the main body 10 closer to the care component 30 is provided with a mating surface 101, and the second detection member 133 is provided on the mating surface 101 and faces the side away from the pump body 15. When the care component 30 is installed on the main body 10, the contact surface 305 is opposite to the mating surface 101, the care component 30 and the main body 10 can be installed with each other along the same axis, and the two surfaces conflicting with each other can make the installation of the care component 30 and the main body 10 more stable. When the first detection member 131 and the second detection member 133 are respectively provided on the contact surface 305 and the mating surface 101, the first detection member 131 and the second detection member 133 are opposite to each other in the direction of the central axis A of the nasal care device 100. The first detection member 131 and the second detection member 133 can also face each other when the care component 30 is installed in place, so that the induction between the two is more sensitive and the obtained detection data is more accurate.

[0080] More specifically, in some embodiments, the first detection member 131 is detachably mounted on the contact surface 305, and the installation method includes but is not limited to snap connection, threaded connection or bolt connection. For example, the first detection member 131 is snapped on the contact surface 305. At this time, the first detection member 131 arranged outside the nursing component 30 is also convenient for disassembly and replacement when damaged. In other embodiments, the first detection member 131 is non-detachably fixed on the contact surface 305, and the fixing method includes but is not limited to gluing connection, hot melt connection or interference connection. For example, the first detection member 131 is glued to the contact surface 305. At this time, the connection between the first detection member 131 and the nursing component 30 is tighter and not easy to fall off. In the case where the first detection member 131 is located outside the nursing component 30 and is arranged on the contact surface 305 closer to the host 10, when the nursing component 30 is installed in place, the distance D between the first detection member 131 and the second detection member 133 arranged on the matching surface 101 is closer, and the induction of the two is more sensitive, and it is not easy to misjudge.

[0081] More specifically, in some embodiments, the types of the first detection member 131 and the second detection member 133 include but are not limited to Hall sensors and magnetic members or transmitters and receivers that can cooperate with each other. In one example, the Hall sensor is a structure that can detect the magnetic field generated by the magnetic member. The Hall sensor can determine whether the care component 30 is installed in place relative to the host 10 based on the magnitude of the magnetic field sensed by the first detection member 131. The Hall sensor can also determine the type of care component 30 installed on the host 10 at this time based on the presence or absence of the magnetic field of the sensed first detection member 131 and / or the type of the magnetic field. In the case where the first detection member 131 is a magnetic member and the second detection member 133 is a Hall sensor, the magnetic member is installed on the care component 30, the Hall sensor is installed on the housing 11 and is electrically connected to the circuit board assembly 50, and the detection data includes the magnetic field data detected by the Hall sensor, and the content of the magnetic field data includes but is not limited to the intensity, direction or presence of the magnetic field. In another example, the transmitter is a structure capable of sending a signal to the receiver, and the receiver can determine whether the first detection member 131 and the second detection member 133 are aligned according to the strength of the received detection signal and / or the presence or absence of the detection signal, thereby determining whether the care component 30 and the host 10 are installed in place. The receiver can also determine the type of care component 30 currently installed on the host 10 according to the type of the received signal. In the case where the first detection member 131 is a transmitter and the second detection member 133 is a receiver, the transmitter is installed on the care component 30, the receiver is installed on the housing 11 and is electrically connected to the circuit board assembly 50, and the detection data includes the strength or presence of the detection signal received by the receiver.

[0082] Also specifically, in some embodiments, the distance D between the first detection member 131 and the second detection member 133 is less than or equal to 2 cm. For example, the size of the distance D includes but is not limited to 0.2 cm, 0.4 cm, 0.6 cm, 0.8 cm, 1.0 cm, 1.1 cm, 1.3 cm, 1.5 cm, 1.7 cm or 2.0 cm. In the case where the distance D between the first detection member 131 and the second detection member 133 is greater than 2 cm, the distance D between the first detection member 131 and the second detection member 133 is too far, and the attenuation and loss of the signal or magnetic field generated by the first detection member 131 when reaching the second detection member 133 are large, so the second detection member 133 is likely to be unable to accurately sense the signal or magnetic field generated by the first detection member 131, resulting in the inability to identify the type of the care component 30. When the distance D between the first detection member 131 and the second detection member 133 is less than or equal to 2 cm, the first detection member 131 and the second detection member 133 can be arranged close to each other, and the attenuation and loss of the signal emitted by the first detection member 131 or the magnetic field generated by the first detection member 131 when reaching the second detection member 133 are smaller, and the induction between the first detection member 131 and the second detection member 133 is more accurate.

[0083] See also Figure 6 and Figure 7 In some embodiments, the pump body 15 is a bidirectional structure capable of ejecting fluid outward or sucking gas inward, and the pump body 15 includes a flow channel port 151 and an air inlet 153, both of which are arranged on the mating surface 101. Among them, the flow channel port 151 can be used to eject liquid or a mixed fluid formed by mixing gas and liquid for fluid flow, and the air inlet 153 can be used to suck gas in the care component 30. When the care component 30 is installed on the host 10, the pump body 15 can be connected to the care component 30 through the flow channel port 151 and / or the air inlet 153. When the care component 30 is installed in place, the first detection member 131 and the second detection member 133 sense each other to determine the type of the care component 30, and the pump body 15 can pump liquid or pump out a gas-liquid mixed fluid into the care component 30 through the flow channel port 151 according to the detection data sent by the detection component 13, and suck gas in the care component 30 through the air inlet 153 according to the detection data sent by the detection component 13.

[0084] See also Figure 1 and Figure 2 In some embodiments, the care component 30 is generally a structure capable of caring for the nasal cavity, and the care component 30 can be detachably mounted on the host 10. When the user needs to use a different care component 30, the host 10 can automatically identify the type of the care component 30 through the detection component 13 and adjust to the corresponding working mode.

[0085] Specifically, please combine Figure 8 In some embodiments, the care component 30 is provided with a connecting portion 307, and the shell 11 is provided with a matching portion 111. The connecting portion 307 and the matching portion 111 are structures that can cooperate with each other. When the connecting portion 307 and the matching portion 111 cooperate with each other, the care component 30 can be installed on the host 10, so that the care component 30 is installed firmly in place relative to the host 10. The connecting portion 307 and the matching portion 111 can also locate the positions of the first detection member 131 respectively provided on the care component 30 and the second detection member 133 provided on the host 10. When the connecting portion 307 and the matching portion 111 cooperate with each other, the first detection member 131 can be directly opposite to the second detection member 133. At this time, the distance D between the two in the direction of the central axis A of the nasal care device 100 is the smallest, and the sensing effect of the two is better.

[0086] More specifically, please combine Figure 2 and Figure 6In some embodiments, the types of care components 30 include but are not limited to nasal washing components 3101, nasal suction components 3103 and / or drug delivery components, and the nasal washing components 3101, nasal suction components 3103 and drug delivery components can be installed on the host 10 to correspond to the pump body 15. The nasal washing component 3101 corresponds to the pumping state of the pump body 15 and the nasal washing mode of the nasal care device 100.

[0087] Please combine Figure 5 and Fig. 9 When the nasal wash component 3101 is installed on the main unit 10, the pump body 15 can pump liquid into the nasal wash component 3101 so that the liquid used for cleaning can be sprayed out through the nasal wash component 3101. The nasal suction component 3103 corresponds to the suction state of the pump body 15 and the nasal suction mode of the nasal cavity care device 100. When the nasal suction component 3103 is installed on the main unit 10, the pump body 15 can extract the gas in the nasal suction component 3103 to reduce the internal air pressure of the nasal suction component 3103, and the liquid in the nasal cavity can be sucked into the nasal suction component 3103 under the action of the air pressure difference. The drug delivery component corresponds to the drug pumping state of the pump body 15 and the drug delivery mode of the nasal cavity care device 100. When the drug delivery component is installed on the main unit 10, the pump body 15 can pump the drug liquid into the drug delivery component so that the drug can be sprayed out through the drug delivery component.

[0088] Further, in some embodiments, the speed of the pump body 15 pumping liquid outward when it is in the liquid pumping state is greater than the speed of the pump body 15 sucking liquid inward when it is in the air suction state. The pump body 15 can quickly discharge liquid outward to clean the nasal cavity, and at this time, external air can quickly enter the pump body 15 and the care component 30 to balance the air pressure. The slow liquid suction speed can reduce the air pressure difference between the inside and outside of the care component 30, avoiding discomfort to the user during use.

[0089] In some embodiments, the speed of pumping liquid outward when the pump body 15 is in the liquid pumping state is greater than the speed of pumping medicine outward when the pump body 15 is in the medicine pumping state. The liquid discharged through the pump body 15 and entering the nasal cavity can quickly clean the nasal cavity, and compared with the nasal washing mode, in the drug administration mode, the medicine entering the nasal cavity needs to stay in the nasal cavity for a longer time to fully act in the nasal cavity, so as to avoid the medicine flowing out of the nasal cavity quickly and causing medicine waste.

[0090] Furthermore, in some embodiments, the flow rate of the pump body 15 pumping liquid outward when it is in the liquid pumping state is greater than the flow rate of the pump body 15 sucking liquid inward when it is in the suction state. In the nasal wash mode, the pump body 15 needs to pump a large amount of liquid into the nasal cavity to fully clean the nasal cavity. Since the flow rate of liquid or dirt in the nasal cavity is small, the flow rate of the pump body 15 sucking liquid or dirt in the nasal suction mode can be less than the flow rate of the pump body 15 pumping liquid outward in the nasal wash mode, so as to better meet the needs of users during use.

[0091] In some embodiments, the flow rate of the pump body 15 pumping liquid outward when it is in the liquid pumping state is greater than the flow rate of the pump body 15 pumping medicine outward when it is in the medicine pumping state. In order to improve the cleaning effect of the nasal cavity, in the nasal wash mode, the pump body 15 can pump out more cleaning liquid to repeatedly wash the inside of the nasal cavity. In the drug administration mode, the amount of medicine that needs to be pumped into the nasal cavity is generally less than the amount of cleaning liquid required to repeatedly wash the inside of the nasal cavity. Therefore, the flow rate of the pump body 15 when pumping medicine will be less than the flow rate when washing the nose, so as to extend the continuous use time of the nasal care device as much as possible.

[0092] Furthermore, in some embodiments, the pressure of the pump body 15 sucking liquid inward when it is in the suction state is greater than the pressure of the pump body 15 pumping liquid outward when it is in the liquid pumping state. In the nasal suction mode, the pump body 15 can extract the gas in the care component, and the care component is closer to a vacuum at this time, so the liquid and dirt deep in the nasal cavity can be sucked out, and the cleaning effect is better. When pumping liquid, the pressure of the pumped liquid is less than the pressure of the sucked liquid, which can reduce the impact of the liquid entering the nasal cavity on the inner wall of the nasal cavity and improve the comfort level during the use of the nasal care device 100.

[0093] In some embodiments, the pressure of the pump body 15 pumping liquid outward when it is in the liquid pumping state is greater than the pressure of the pump body 15 pumping medicine outward when it is in the medicine pumping state. In order to improve the cleaning effect of the nasal cavity, compared with the drug administration mode, the liquid pumped out by the pump body 15 in the nasal wash mode can produce a greater impact force on the inside of the nasal cavity, and the nasal cavity is cleaned more thoroughly. In the drug administration mode, the pump body 15 only needs to pump the medicine into the nasal cavity. Therefore, compared with the case where the pump body 15 pumps liquid outward, the pressure of the pump body 15 pumping medicine outward will be smaller, so that the medicine can accurately reach the part of the nasal cavity that needs to be administered.

[0094] In some embodiments, the first detection member 131 may include multiple, each of which can be installed on a care component 30, and each of which can be mutually induced with the second detection member 133 to send different detection data. In the case where the first detection member 131 is a magnetic member, the magnetic field strengths of the multiple first detection members 131 provided on different care components 30 are different or the magnetism of the multiple first detection members 131 facing the side of the host 10 is different. In the case where the first detection member 131 is a transmitter, the types of signals sent by the multiple first detection members 131 provided on different care components 30 are different or the intensity of the signals is different. For example: the care component 30 includes a nasal washing component 3101 and a nasal suction component 3103 that can be replaced with each other, the second detection member 133 is provided on the host 10, the first detection member 131 includes two and is respectively provided on the nasal washing component 3101 and the nasal suction component 3103, and the second detection member 133 is used to cooperate with the two first detection members 131 respectively, so that the pump body 15 enters the corresponding working state. In the case where the first detection member 131 is a magnetic member and the second detection member 133 is a Hall sensor, in one example, the magnetic field strength generated by the first detection member 131 provided in the nasal washing component 3101 is different from the magnetic field strength generated by the first detection member 131 provided in the nasal suction component 3103. In another example, the magnetic field direction of the first detection member 131 provided in the nasal washing component 3101 toward the second detection member 133 is different from the magnetic field direction of the first detection member 131 provided in the nasal suction component 3103 toward the second detection member 133. Therefore, when different care components 30 are installed on the host 10, the second detection member 133 can sense different magnetic field strengths and different magnetic field directions, and the second detection member 133 can judge the type of care component 30 currently installed on the host 10 based on this, and control the pump body 15 to be in different working states.

[0095] In other embodiments, only one of the nasal suction component 3103 and the nasal washing component 3101 can be provided with the first detection member 131, and the second detection member 133 is provided on the host 10 and is used to cooperate with the first detection member 131 so that the pump body 15 enters the corresponding working state. For example: when the nasal suction component 3103 provided with the first detection member 131 is installed on the host 10, the second detection member 133 can receive or sense the signal or magnetic field emitted by the first detection member 131, and the second detection member 133 can output detection data to drive the pump body 15 to extract the gas in the nasal suction component 3103 through the circuit board assembly 50, so that the nasal suction component 3103 can suck the liquid in the nasal cavity. When the nasal washing component 3101 without the first detection member 131 is installed on the host 10, the second detection member 133 cannot receive the signal or magnetic field emitted by the first detection member 131, and the second detection member 133 can output detection data to control the pump body 15 to spray fluid into the nasal washing component 3101 to clean the nasal cavity.

[0096] See also Figure 2 and Figure 6 , and combined with Figure 3 and Figure 7 In some embodiments, the care component 30 includes a care head 31 and a liquid storage tank 33. Depending on the type of the care component 30, the structure of the care head 31 and the structure of the liquid storage tank 33 are also different. The care head 31 can directly contact the inside of the nasal cavity to allow liquid to flow into the liquid storage cavity 331 or allow fluid to flow from the care head 31 to the inside of the nasal cavity. The liquid storage cavity 331 is a structure for storing liquid. The liquid storage tank 33 includes a liquid storage cavity 331. The liquid storage cavity 331 is used to store fluid. The liquid storage cavity 331 can store both clean cleaning liquid and waste liquid flowing out of the nasal cavity. The liquid storage cavity 331 is connected to the pump body 15 so that the pump body 15 can pump fluid into the liquid storage cavity 331. The pump body 15 can also extract gas from the liquid storage cavity 331.

[0097] Specifically, in some embodiments, the liquid storage tank 33 is provided with a top and a bottom facing each other, the top of the liquid storage tank 33 faces the care head 31, and the bottom of the liquid storage tank 33 faces the main unit 10. The care head 31 is detachably arranged on the top of the liquid storage tank 33, the main unit 10 is arranged on the bottom of the liquid storage tank 33, and the liquid storage tank 33 is connected to the housing 11. The material of the liquid storage tank 33 includes but is not limited to metal, plastic or silicone, etc. Among them, the outer contour of the cross section of the liquid storage tank 33 can be a regular shape (for example: a perfect circle, an ellipse, a polygon, etc.), or an irregular shape.

[0098] More specifically, in some embodiments, the liquid storage tank 33 is provided with an inlet 333 and an outlet 335. The inlet 333 and the outlet 335 are arranged at intervals from each other and are respectively connected to the liquid storage chamber 331. When the care component 30 is installed on the host 10, the liquid storage chamber 331 can be connected to the pump body 15 so that gas enters the pump body 15 or fluid enters the liquid storage chamber 331. In some embodiments, when the care component 30 is a nasal suction component 3103, the outlet 335 of the liquid storage tank 33 is connected to the care head 31 so that the liquid in the nasal cavity flows into the liquid storage chamber 331 through the care head 31, and the inlet 333 of the liquid storage tank 33 is used to communicate with the suction port 153 of the pump body 15 so that the gas in the liquid storage chamber 331 is extracted. In other embodiments, when the care component 30 is a nasal wash component 3101, the inlet 333 of the liquid storage tank 33 is used to communicate with the flow channel opening 151 to allow liquid to enter the liquid storage cavity 331, and the outlet 335 of the liquid storage tank 33 is used to communicate with the nasal cavity through the care head 31 to spray the fluid pumped out by the pump body 15 outward.
