[0003] The float in a water purifier is used for automatic liquid level control. In existing technology, the float typically uses a float holder and a float with a clearance fit. When the liquid level fluctuates, the float moves up and down relative to the holder.

Detailed Implementation

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0055] The float in a water purifier is a component used to automatically control the liquid level. When first used, the float and the float rod work together without any problems. However, after prolonged use, dirt or ice on the float rod can cause the float to get stuck on the float rod. The working state of the float has a significant impact on the user experience and safety of the water purifier. Regularly having after-sales personnel come to the site to manually replace the float mechanism is costly and provides a poor user experience.

[0056] like Figure 1 As shown in the figure, this application discloses a float assembly for a water purifier. The float assembly includes a float fixing rod assembly 1, a motor assembly 2, and a Hall sensor assembly 3. The float fixing rod assembly 1 and the motor assembly 2 are in contact with each other.

[0057] The float fixing rod assembly 1 includes a fixing rod 101, a heating structure 102 and a float 103. The heating structure 102 is disposed inside the fixing rod 101, and the float 103 is slidably connected to the fixing rod 101.

[0058] The Hall sensor assembly 3 includes a Hall sensor 301 and a magnet 302. The Hall sensor 3 is disposed at a preset position on the outer surface of the water purifier housing. The magnet 302 is embedded in one end of the float 103 near the water purifier housing. The magnet 302 is within the sensing range of the Hall sensor 3.

[0059] Optionally, the water purifier housing includes an inlet and an outlet, wherein the inlet is controlled by an inlet valve and the outlet is controlled by an outlet valve.

[0060] Optionally, the amount of liquid inside the water purifier can be controlled by using an inlet valve and an outlet valve.

[0061] Optionally, the float 103 is displaced on the fixed rod 101 when the liquid level changes, and the float 103 is used to react to the liquid position.

[0062] Optionally, such as Figure 2 As shown, the magnet 302 is embedded in one end of the float 103 near the water purifier housing. The magnet 302 is used to be sensed by the Hall sensor 3 to reflect the position of the float 103.

[0063] Optionally, the Hall sensing device 301 is a Hall sensor used to measure magnetic fields. In addition, it can also measure physical quantities that generate and affect magnetic fields, thereby performing position measurement.

[0064] Optionally, the Hall sensor 301 includes a first sensor 3011 and a second sensor 3012.

[0065] The first sensing device 3011 is disposed at a first preset position on the outer surface of the water purifier housing, and the second sensing device 3011 is disposed at a second preset position on the outer surface of the water purifier housing; the first preset position is lower than the second preset position.

[0066] Optionally, the first sensing device 3011 is disposed at a first preset position 1A on the outer surface of the water purifier housing. When the first sensing device 3011 senses the magnet 302, it indicates that the float 103 is located at position 1A.

[0067] Optionally, the second sensing device 3012 is disposed at a second preset position 2A on the outer surface of the water purifier housing. When the second sensing device 3012 senses the magnet 302, it indicates that the float 103 is located at position 2A.

[0068] In this embodiment, positioning detection is performed using the Hall sensor component 3, which has a simple structure, adopts non-contact positioning, and improves the accuracy of detection.

[0069] Optionally, the float fixing rod assembly 1 of the water purifier further includes a vertical sensing device 104.

[0070] The vertical sensing device 104 is fixedly connected to the top end of the fixed rod 101.

[0071] Optionally, the vertical sensing device 104 is an acceleration sensor, which may be an accelerometer, a gyroscope, or an electronic compass.

[0072] Optionally, the vertical sensing device 104 detects the vertical state of the float fixing rod assembly 1 of the water purifier by detecting gravitational acceleration.

[0073] Optionally, the heating structure 102 is a heating wire.

[0074] The heating wires are evenly arranged inside the fixing rod 101, so the heating wires are used to heat the fixing rod 101.

[0075] Alternatively, the heating wire is a thin, conductive material made of a resistance alloy. Heat is generated by passing an electric current through the heating wire, thereby achieving the purpose of heating.

[0076] Optionally, the motor assembly 2 includes a motor 201 and an eccentric wheel 202.

[0077] The output end of the motor 201 is fixedly connected to the shaft hole of the eccentric wheel 202, and the outer circumferential surface of the eccentric wheel 202 is in contact with the top of the fixed rod 101.

[0078] Optionally, the motor assembly 2 is an eccentric wheel motor, where the vibration is generated by the inertia caused by the rotation of the motor 201 driving the eccentric wheel 202. Specifically, the eccentric wheel 202 is a wheel with its shaft hole offset to one side.

[0079] This application also discloses a water purifier, which includes the float assembly, housing, inlet valve, and outlet valve described above.

[0080] The inlet valve is connected to a preset inlet position on the side of the water purifier housing, and the outlet valve is connected to a preset outlet position on the side of the water purifier housing.

[0081] The float fixing rod assembly 1 is disposed inside the water purifier housing, and the bottom end of the float fixing rod assembly 1 is fixedly connected to the bottom of the water purifier housing.

[0082] In this embodiment, a self-heating fixing rod is used in conjunction with the vibration of an eccentric wheel motor to drive the fixing rod to vibrate in the horizontal direction, shaking off the dirt on the fixed float rod, thereby shaking off the float stuck on the float rod and solving the problem of the float getting stuck.

[0083] like Figure 3 As shown in the embodiments, this application also discloses a control method for a float assembly of a water purifier. The control method is used to control the float assembly of the water purifier as described in any of the above embodiments, and the method includes steps S101 to S105.

[0084] S101, when the water purifier is in working condition, a sensing analysis is performed based on the Hall sensor component 3 to obtain the sensing analysis result.

[0085] In one possible implementation, the operating state includes a water inlet state, which indicates that the water inlet valve of the water purifier is in the open state and the water outlet valve of the water purifier is in the closed state.

[0086] When the water purifier is in operation, the sensor analysis is performed based on the Hall sensor component 3 to obtain the sensor analysis results, including:

[0087] When the water purifier is in the water inlet state, the position information of the float is determined based on the Hall sensor component 3;

[0088] If the location information indicates that the float 103 meets the first preset movement condition within a first preset time, it is determined that the sensing analysis result is that the float 103 does not have any malfunction.

[0089] If the location information indicates that the float 103 does not meet the first preset movement condition within a first preset time, the sensing analysis result is determined to be that the float 103 has a working abnormality.

[0090] In one possible implementation, such as Figure 4 As shown, the water inlet detection float is used. At this time, there is no liquid in the water purifier. The water inlet valve K1 is opened and the water outlet valve K2 is closed, so that the water purifier is in the water inlet state.

[0091] In one possible implementation, such as Figure 4 As shown, timing begins when the inlet valve K1 is opened and the outlet valve K2 is closed. After time 1X, if the first sensing device 3011 of the Hall sensor assembly 3 senses the float 103, and after time 2X, if the second sensing device 3012 of the Hall sensor assembly 3 senses the float 103, it is determined that the inlet float is normal, and the sensing analysis result is that the float 103 does not have any abnormal operation.

[0092] In one possible implementation, such as Figure 4 As shown, the timing starts when the inlet valve K1 is opened and the outlet valve K2 is closed. After time 1X, if the first sensing device 3011 of the Hall sensor component 3 does not sense the float 103, the sensing analysis result is determined to be that the float 103 has a working abnormality and the float anti-jamming procedure needs to be entered.

[0093] In one possible implementation, such as Figure 4 As shown, the timing starts when the inlet valve K1 is opened and the outlet valve K2 is closed. After time 2X, if the second sensing device 3012 of the Hall sensor component 3 does not sense the float 103, the sensing analysis result is determined to be that the float 103 has a working abnormality and the float anti-jamming procedure needs to be entered.

[0094] In this embodiment, the water purifier is subjected to sensing analysis based on the Hall sensor component 3 to obtain the sensing analysis results, which improves the grasp of the working state of the float of the water purifier and thus improves the accuracy of detecting float jamming.

[0095] In one possible implementation, the operating state further includes a water outlet state, which indicates that the inlet valve of the water purifier is in a closed state and the outlet valve of the water purifier is in an open state.

[0096] When the water purifier is in operation, the sensor performs a sensing analysis based on the Hall sensor component (3) to obtain the sensing analysis results, including:

[0097] When the water purifier is in the water outlet state, the position information of the float (103) is determined based on the Hall sensor component (3);

[0098] If the location information indicates that the float meets the second preset movement condition within a second preset time, the sensing analysis result is determined to be that the float (103) does not have a working abnormality;

[0099] If the location information indicates that the float does not meet the second preset movement condition within a second preset time, the sensing analysis result is determined to be that the float (103) has a working abnormality.

[0100] In one possible implementation, such as Figure 5 As shown, the water outlet detection float is used. At this time, the liquid level in the water purifier is at the preset liquid level position. The inlet valve K1 is closed and the outlet valve K2 is opened, so that the water purifier is in the water outlet state.

[0101] In one possible implementation, such as Figure 5 As shown, timing begins when the inlet valve K1 is closed and the outlet valve K2 is opened. After time 1X, if the second sensing device 3012 of the Hall sensor assembly 3 senses the float 103, and after time 2X, if the first sensing device 3011 of the Hall sensor assembly 3 senses the float 103, it is determined that the outlet float is normal, and the sensing analysis result is that the float 103 does not have any abnormal operation.

[0102] In one possible implementation, such as Figure 5 As shown, the timing starts when the inlet valve K1 is closed and the outlet valve K2 is opened. After time 1X, if the second sensing device 3012 of the Hall sensor component 3 does not sense the float 103, the sensing analysis result is determined to be that the float 103 has a working abnormality and the float anti-jamming procedure needs to be entered.

[0103] In one possible implementation, such as Figure 5 As shown, the timing starts when the inlet valve K1 is closed and the outlet valve K2 is opened. After time 2X, if the first sensing device 3011 of the Hall sensor component 3 does not sense the float 103, the sensing analysis result is determined to be that the float 103 has a working abnormality and the float anti-jamming procedure needs to be entered.

[0104] S103, based on the induction analysis results, determine the control information for the motor assembly 2 and the heating structure 102.

[0105] In one possible implementation, the induction analysis results include the presence of a malfunction in the float.

[0106] The determination of control information for the motor assembly 2 and the heating structure 102 based on the induction analysis results includes:

[0107] If the sensing analysis result indicates that the float 103 is malfunctioning, the current detection data of the vertical sensing device 104 is acquired.

[0108] Based on the current detection data, an installation analysis is performed to obtain the installation analysis results;

[0109] If the installation analysis results indicate that there is an installation abnormality in the float fixing rod assembly 1, a warning will be issued to the user;

[0110] If the installation analysis results indicate that there is no installation abnormality in the float fixing rod assembly 1, the control information for the motor assembly 2 and the heating structure 102 is determined to be: control the heating structure 102 to heat the fixing rod 101 for a preset heating time, and then control the motor assembly 2 to run for a preset vibration time.

[0111] In one possible implementation, if the sensing analysis result indicates that the float 103 is malfunctioning, the control information for the motor assembly 2 and the heating structure 102 is determined to enter the anti-jamming program.

[0112] In one possible implementation, such as Figure 6 As shown, the method further includes detecting the cumulative working time T of the water purifier, and executing an anti-jamming program on the water purifier when the cumulative working time T exceeds the preset working time T1.

[0113] In one possible implementation, such as Figure 7 As shown, the anti-jamming program is entered to perform float anti-jamming detection, read the current detection data of the vertical sensing device, calculate the angle between the fixing rod 101 and the bottom plane of the water purifier shell based on the current detection data, and determine that the float fixing rod assembly 1 has an installation abnormality when the angle is less than the preset angle, and issue a warning to the user. The preset angle is preferably 85°.

[0114] In one possible implementation, such as Figure 7 As shown, when the included angle is greater than or equal to a preset angle, the heating structure 102 is used to heat the fixed rod 101 for a preset heating time T2 to eliminate the float jamming caused by icing.

[0115] In one possible implementation, such as Figure 7As shown, after heating the fixed rod 101 for a preset heating time T2, the motor assembly 2 is controlled to run for a preset vibration time, preferably 5s.

[0116] In this embodiment, different detection methods are designed for different working states of water inlet and outlet to detect whether there is any abnormality in the operation of the float assembly of the water purifier. Based on the detection structure, control information is determined, which improves the accuracy of the control information.

[0117] S105, based on the control information, control the motor assembly 2 and the heating structure 102 so that the float 103 can accurately express the current liquid level.

[0118] In one possible implementation, after controlling the motor assembly 2 and the heating structure 102 based on the control information, the method further includes:

[0119] The position sensing processing of the float 103 is performed based on the Hall sensor component 3 to obtain the position sensing processing result;

[0120] If the position sensing processing result indicates that the float 103 does not meet the preset position conditions, it is determined that the float 103 is damaged and a warning is issued to the user.

[0121] In one possible implementation, such as Figure 7 As shown, after controlling the motor assembly 2 and the heating structure 102 based on the control information, the position of the float 103 is detected by the Hall sensor assembly 3. If the position of the float 103 is not in the preset position, it is determined that the float 103 is damaged and a warning is given to the user.

[0122] In this implementation, a warning is issued to the user in case of float damage, facilitating further handling by the user to ensure the water purifier functions properly and improves the user experience.

[0123] like Figure 8 As shown in the illustration, this application also discloses a control device 800 for a float assembly of a water purifier, used to control the float assembly of the water purifier described in any of the above embodiments, comprising:
