[0002] Most baby bottle cleaning equipment is equipped with a clean water tank and a dirty water tank, designed so that both can be easily removed from the equipment for cleaning. Taking the clean water tank as an example, since sufficient water is needed in the tank during cleaning, the current practice involves an automatic water level sensor that extends into the tank to detect the water level and determine whether to start cleaning or add more water. However, because the clean water tank is frequently removed, the water level sensor must be removed and reinstalled each time, which is inconvenient. Summary of the Invention

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-7 A baby bottle cleaning device includes a housing 1, on which a cleaning chamber 101 is provided. The cleaning chamber 101 has an item placement opening 102, through which items to be cleaned (such as baby bottles) can be placed into the cleaning chamber 101, or the cleaned items can be taken out.

[0020] In this embodiment, the baby bottle cleaning equipment further includes a cleaning system 2, which is used to clean the items in the cleaning chamber 101. The cleaning medium used in the cleaning system 2 may include water, such as clean water or reused water; or other liquids or other media that have a cleaning effect or work in conjunction with other media to produce a cleaning effect, such as electrolyzed water or steam mentioned below. In other embodiments, commonly used organic or inorganic cleaning solutions for baby bottle cleaning may also be used.

[0021] In some embodiments, the cleaning system includes a liquid supply assembly and a water injection line 201. The liquid supply assembly supplies liquid cleaning medium to the water injection line 201, and the water injection line 201 injects liquid into the cleaning chamber 101 for liquid cleaning.

[0022] In some embodiments, the liquid supply assembly may be a water supply line 201 that supplies water from an external water source.

[0023] For example, the liquid supply component includes a water receiving interface 202, and a water receiving pipe from an external water source is connected to the water receiving interface 202 to supply water to the water receiving interface 202.

[0024] The water inlet can be directly connected to the water supply pipeline, and water can be supplied to the water supply pipeline by the water pressure of the external water source.

[0025] The water inlet can be connected to the water supply line via at least one intermediate component. For example, the water inlet can be connected to the water supply line via an intermediate inlet pipe.

[0026] In some embodiments, the cleaning system 2 includes a liquid storage tank 207, and the liquid supply component may be a water supply pipeline 201 that supplies water from the liquid storage tank 204 to the water supply tank 207.

[0027] In some embodiments, the liquid supply assembly includes a water inlet and a liquid storage tank.

[0028] In some embodiments, the liquid supply assembly further includes an inlet pipe 203 and a first switching valve 204. The first switching valve 204 has at least three pipe interfaces and is capable of controlling at least one pipe interface to switch communication with the other two pipe interfaces. For example, it can control the second end interface of the first switching valve to switch communication with the first end interface and the third end interface.

[0029] In some embodiments, the first end interface of the first switching valve is connected to the water receiving interface, the second end interface of the first switching valve is connected to the water supply interface of the storage tank, and the third end interface of the first switching valve is connected to the water inlet pipe.

[0030] In some embodiments, the first switching valve is, for example, a three-way solenoid valve.

[0031] The connection state can be controlled by a three-way solenoid valve. For example, the first end of the three-way solenoid valve can be connected to the second end, so that the liquid storage tank 207 can supply water to the cleaning chamber 1 through the water inlet pipe 203; or the third end of the three-way solenoid valve can be connected to the second end, so that an external water source can add liquid to the liquid storage tank 207.

[0032] In some embodiments, the liquid supply assembly further includes an external water detection unit, which is used to detect whether the water inlet is in a water supply state, so that when water needs to be supplied by an external water source, the control system of the bottle cleaning equipment can accurately control the switch to external water supply.

[0033] In some embodiments, the external water detection unit includes an external water connection status sensor 205, which is used to detect whether the water inlet 202 is connected to a water pipe (or other connectors for water supply).

[0034] The external water connection status sensor, such as a proximity sensor, can confirm the connection status when the external pipe is connected to the water inlet, so that the control system 3 of the bottle cleaning equipment can also confirm the connection status and accurately control whether to switch to external water supply when water needs to be supplied from an external source.

[0035] The external water connection status sensor is, for example, a Hall sensor. The water inlet has a magnetic cover. After the cover is removed, the Hall sensor can confirm the connection status, so that the control system 3 of the bottle cleaning equipment can also confirm the connection status. When it is necessary to supply water through an external water source, it can accurately control whether to switch to external water supply.

[0036] For example, controlling the first switching valve to switch to water supply from an external water source through the water inlet to add water to the storage tank.

[0037] In some embodiments, the external water detection unit further includes a water supply status sensor 208 for detecting whether there is external water supply or detecting the amount of external water supply.

[0038] For example, the water supply status sensor is a water pressure sensor installed at the water inlet. When water is connected to the water inlet, the control system can know the water pressure information detected by the water pressure sensor, so as to more accurately control the switch to external water supply.

[0039] For example, a water supply status sensor is a water flow sensor (such as a Hall effect flow meter) installed at the water inlet. The control system can detect the presence of water through the water flow sensor, thereby enabling more precise control to switch to external water supply.

[0040] When the control is switched to external water supply, the external water supply volume can be detected simultaneously.

[0041] In some embodiments, the liquid supply assembly further includes a pressure reducing valve 206 disposed at the water inlet. The pressure reducing valve 206 is used to reduce and stabilize the pipeline pressure, regulate the high-pressure water from the external water source to a safe range, and prevent excessive water pressure from damaging the pipeline and the corresponding water-using components.

[0042] The pressure reducing valve can be a common tap water pressure reducing valve.

[0043] In some embodiments, the liquid storage tank 207 has a water inlet 2071, through which the user can manually add water.

[0044] When used in conjunction with the first switching valve 204, it can form an electrically controlled liquid addition system for the liquid storage tank 207 controlled by an external water source and the first switching valve, as well as a manual liquid addition system where the user automatically adds water. The water addition methods are diverse and convenient to use.

[0045] In some embodiments, for example, the water inlet 2071 may be located on the top of the liquid storage tank 207.

[0046] In some embodiments, the housing or liquid storage tank is provided with a water injection protective cover 103 for covering the water inlet 2071, and the water injection protective cover 103 is openable. For example, it can be flipped up to open.

[0047] Users can manually add water to the storage tank by flipping the lid upwards. After adding water, the water filling protective cover 103 can be closed to prevent external contaminants from entering the storage tank 207 through the water inlet 2071, effectively ensuring the cleanliness of the inside of the storage tank.

[0048] In some embodiments, the water injection protective cover 103 is rotatably connected to the housing 1, the water injection protective cover 103 is located above the liquid storage tank 207, and the water injection protective cover 103 is correspondingly downward and closed on the water injection port 2071.

[0049] For example, one side of the water-filled protective cover is connected to the top of the casing via a pivot.

[0050] In some embodiments, the liquid storage tank 207 is detachably connected to the housing 1, so that the liquid storage tank 207 can be removed from the housing 1 for easy cleaning of the liquid storage tank and other operations.

[0051] In some embodiments, the housing has a reservoir for accommodating a reservoir, and the reservoir is inserted into the reservoir from the opening of the reservoir.

[0052] The liquid storage tank can be positioned horizontally, vertically, or diagonally within the liquid storage tank reservoir, or positioned along a specified path or direction within the liquid storage tank reservoir.

[0053] In some embodiments, the housing is provided with a coupler a corresponding to the water inlet pipe of the liquid supply assembly, and the liquid storage tank is provided with a coupler b that cooperates with the coupler a and corresponds to the water inlet of the liquid storage tank.

[0054] When the liquid storage tank is connected to the housing (as described above, the liquid storage tank is placed in the liquid storage tank receiving slot), coupler a and coupler b are coupled to each other to connect the water inlet pipe of the liquid supply component with the inside of the liquid storage tank.

[0055] In some embodiments, the liquid storage tank receiving groove has a joint inner wall corresponding to the liquid storage tank, and the liquid storage tank has a joint side surface corresponding to the joint inner wall of the liquid storage tank receiving groove; coupler a is disposed on the joint inner wall of the liquid storage tank receiving groove, and coupler b is disposed on the joint side surface of the liquid storage tank; when the liquid storage tank is placed into the liquid storage tank receiving groove from the slot, coupler a and coupler b are coupled accordingly.

[0056] In some embodiments, one side of the housing 1 has a liquid tank receiving groove 104 for accommodating a liquid tank, and the liquid tank can be correspondingly inserted laterally into the liquid tank receiving groove 104.

[0057] In some embodiments, when the liquid storage tank 104 is provided, the water inlet on the top of the liquid storage tank can correspond to the water inlet protective cover on the housing after being snapped into place.

[0058] In some embodiments, the liquid storage tank receiving groove has a mating inner wall opposite to the groove opening, the liquid storage tank is laterally inserted into the liquid storage tank receiving groove, and the liquid storage tank has a mating side corresponding to the mating inner wall of the liquid storage tank receiving groove.

[0059] The inner wall of the liquid storage tank and the side wall of the liquid storage tank are equipped with couplers that cooperate with each other, namely coupler a209 and coupler b210.

[0060] In some embodiments, the coupler a209 on the inner wall is connected to the second end opening of the first switching valve 204, and the coupler b210 on the side is connected to the water inlet of the liquid storage tank 207.

[0061] When the liquid storage tank is inserted horizontally into place, the coupler a on the inner wall and the coupler b on the side are coupled to each other, so that the second end opening of the first switching valve is connected to the water inlet of the liquid storage tank, that is, the second end opening of the first switching valve is connected to the inside of the liquid storage tank.

[0062] In some embodiments, the coupler a209 includes, for example, a first connecting seat 2091 disposed on the inner wall of the joint, a first communicating hole 2092 formed on the first connecting seat 2091, and the first communicating hole 902 communicating with the second end opening of the first switching valve 204.

[0063] Coupler b210 includes, for example, a first connecting groove 2101 formed on the mating side of the liquid storage tank 207, a first connecting seat 2091 corresponding to the first connecting groove 2101, a first insertion pipe 2102 connected to the first connecting groove 2101, the first insertion pipe 2102 being inserted into and engaged with the first communicating hole 2092, and the first insertion pipe 2102 communicating with the water inlet of the liquid storage tank 207.

[0064] When the liquid storage tank is inserted horizontally into the liquid storage tank receiving slot, the first connecting seat is inserted into the first connecting slot, and the first plug pipe is inserted into the first connecting hole, forming mutual coupling and connection of the interface, that is, coupler a and coupler b are coupled to each other.

[0065] In some embodiments, a sealing ring is also provided in the first connecting hole. When the first insertion tube is inserted into the first connecting hole, the first insertion tube is correspondingly inserted into the sealing ring. The sealing ring makes it easy for water to leak when water is flowing after coupling.

[0066] Similarly, in some embodiments, when the liquid storage tank is placed vertically or obliquely into the liquid storage tank receiving slot, coupler a and coupler b can also refer to the above design; unlike the horizontal insertion coupling of coupler a and coupler b when the liquid storage tank is placed horizontally into the liquid storage tank receiving slot, when the liquid storage tank is placed vertically into the liquid storage tank receiving slot, the corresponding positions of coupler a and coupler b are changed to vertical insertion coupling or oblique insertion coupling.

[0067] In some embodiments, the housing 1 is provided with a first positioning sensor for detecting that the liquid storage tank 207 is installed in place.

[0068] The control system 3 uses the first positioning sensor to confirm whether the liquid storage tank 207 is installed in place (e.g., whether it is locked in place), thereby more accurately controlling whether water is supplied from the liquid storage tank to the cleaning chamber.

[0069] In some embodiments, the first positioning sensor is, for example, a contact sensor such as a micro switch. When the liquid tank is inserted into position, the corresponding part on the liquid tank will press and trigger the contact of the micro switch, so that the control system can confirm that the liquid tank is inserted into position through the first positioning sensor.

[0070] In some embodiments, the first positioning sensor is a non-contact sensor, such as a magnetic sensor. When the liquid tank is inserted into position, the corresponding part on the liquid tank (such as a magnet installed on the liquid tank) is sensed by the magnetic sensor to obtain a sensing trigger signal, so that the control system can confirm that the liquid tank is inserted into position through the first positioning sensor.

[0071] In some embodiments, a first handle 212 is connected to the side of the liquid storage tank 207, and the user can conveniently pull the liquid storage tank 207 out of the liquid storage tank receiving slot 104 through the first handle 212.

[0072] In some embodiments, the top wall of the liquid storage tank 104 forms a stop against the top of the liquid storage tank 207. When it is necessary to lift this bottle cleaning device, it can be easily grasped and lifted by means of the first handle and the connection and stop effect of the coupler and the top wall of the liquid storage tank.

[0073] In some embodiments, the liquid storage tank 207 may be made of a light-transmitting material, such as plastic or glass with good light transmittance. This allows the user to more easily see the water level or volume inside the liquid storage tank from the outside.

[0074] In some embodiments, a liquid tank level sensor 213 for detecting the water level in the liquid tank 207 is also included.

[0075] The control system 3 can determine, based on the detected water level information in the storage tank, whether to start adding water to the storage tank, control the completion of adding water to the storage tank, switch to supplying water from the storage tank to the cleaning chamber, and perform other relevant controls suitable for controlling the water level in the storage tank.

[0076] In some embodiments, the liquid level sensor 213 is, for example, a non-contact liquid level sensor, such as the liquid level sensor 213 being mounted on the housing 1, which detects the water level in the liquid level tank 207 by sensing in the air.

[0077] In some embodiments, the liquid tank level sensor 213 includes a plurality of capacitive sensors, each of which detects the water level at a corresponding height.

[0078] For example, five capacitive sensors can be set up, each corresponding to detect 20% of the water level. The first capacitive sensor detects 1 / 5 of the water level, the second detects 2 / 5, the third detects 3 / 5, the fourth detects 4 / 5, and the fifth detects 5 / 5.

[0079] The liquid level sensor 213 also includes a signal control unit (such as a control board with a control chip). The signals from multiple capacitive sensors are first sent to the signal control unit, and then the signal control unit transmits signals to the control system, so that the multiple capacitive sensors form a multi-segment capacitive sensor.

[0080] In some embodiments, the liquid supply assembly further includes a liquid supply pump 214, the inlet of which is connected to the water inlet pipe 203, and the outlet of which is used to supply water to the cleaning chamber 101.

[0081] The liquid supply pump 214 can supply liquid under pump pressure, for example, it can supply the liquid in the storage tank 207 to the cleaning chamber 101 under pump pressure.

[0082] In some embodiments, the liquid supply pump 214 is a water pump with metering function. The control system 3 can obtain the water flow rate accordingly. Correspondingly, the control system can correlate the pumping speed of the liquid supply pump with the water flow rate through water flow rate feedback. For example, the pumping speed of the liquid supply pump can be adjusted according to different usage needs to obtain different water flow rates. For example, the pumping speed of the liquid supply pump can be controlled to achieve a water flow rate of 600 ml / min, or the pumping speed can be controlled to achieve a water flow rate of 98 ml / min.

[0083] In some embodiments, the supply pump 214 may be, for example, a water pump with a Hall effect flow meter.

[0084] In some embodiments, the liquid supply assembly further includes an electric heater 215, which is used to heat the liquid to obtain hot water or to heat the liquid to obtain steam.

[0085] The electric heater 215 has a hot water pipe 2151 with an inlet and an outlet connected to the water injection pipe 203. The electric heater 215 also has an electric heating element 2152 located near the hot water pipe 2151 and used to heat the hot water pipe 2151.

[0086] Water from inlet pipe 203 is supplied to the inlet of hot water pipe 2151; or, if a liquid supply pump 214 is provided, the outlet of the liquid supply pump 214 is connected to the inlet of hot water pipe 2151 through a fitting, and water is pumped to the inlet of hot water pipe 2151 by the liquid supply pump 214.

[0087] After entering the hot water pipe 2151, the water is heated to form hot water or steam, which is then supplied to the cleaning chamber 101.

[0088] In some embodiments, when a liquid supply pump 214 and an electric heater 215 are provided, the control system 3 can controllably supply hot water to the cleaning chamber 101 or switch to supplying steam by controlling the water flow rate, heating power, etc.

[0089] For example, if the electric heating element is heated to a specified heating power of 1500W, there will be a certain difference between controlling the water flow rate at 600ml / min and controlling the water flow rate at 98ml / min.

[0090] For example, when the water flow rate is controlled at 600 ml / min by the liquid supply pump, the water supplied to the cleaning chamber after heating is high-temperature water, such as water at around 55°C.

[0091] For example, when the water flow rate is controlled at 98 ml / min by the liquid supply pump, high-temperature steam, such as 100°C water steam, is supplied to the cleaning pump after heating.

[0092] In some embodiments, the electric heater 215 is placed outside the cleaning chamber 101.

[0093] In some embodiments, the electric heater 215 also includes a heater temperature sensor 2153 for detecting the temperature of the electric heating element. The control system 3 can confirm the current temperature of the electric heating element through the heater temperature sensor 2153, and can perform corresponding safety controls when the temperature is too high. For example, the temperature of the electric heating element can be detected in real time, and if it exceeds 110°C, heating can be stopped.

[0094] In some embodiments, the baby bottle cleaning equipment further includes a circulating rinsing assembly 4, which can circulate the liquid in the cleaning chamber 101 to form a circulating rinsing operation.

[0095] In some embodiments, the circulating flushing assembly 4 includes a circulating water pump 401, the inlet of which is connected to the cleaning chamber 101, and the outlet of which is connected to the cleaning chamber 101.

[0096] In some embodiments, the inlet of the circulating water pump 401 is connected to the bottom of the cleaning chamber 101. Under the action of gravity, the liquid in the cleaning chamber 101 first concentrates at the bottom of the cleaning chamber 101, so that the circulating water pump 401 can better achieve water circulation.

[0097] In some embodiments, a flushing pipe 402 is provided in the cleaning chamber 101, and the outlet of the circulating water pump 401 is connected to the flushing pipe 402, so that the circulating liquid can be flushed in a specified manner under the guidance of the flushing pipe 402.

[0098] The flushing pipe 402 can be configured as a rotating arm or a hook bracket, which are commonly used for cleaning baby bottles.

[0099] In some embodiments, the circulating flushing assembly further includes a temperature sensor for detecting the temperature of the circulating water pump.

[0100] In some embodiments, the baby bottle cleaning equipment further includes an electrolyzed water module 5, which is used to electrolyze water, such as electrolyzing tap water into hydroxyl and oxygen groups, and using the chlorine dioxide and free radicals in the tap water to electrolyze and generate hypochlorous acid and hydrocarbon groups, so as to better clean items in the cleaning room.

[0101] In some embodiments, the water electrolysis module 5 is disposed at the bottom of the cleaning chamber 101 so that when water is used as the cleaning medium, the water electrolysis module 5 can be used to electrolyze water for better cleaning.

[0102] When a circulating water pump 401 is present, the electrolyzed water obtained by the electrolysis of the electrolyzed water module 5 can also be driven by the circulating water pump 401, which can simultaneously clean the circulating pipeline, such as the flushing pipeline and the connecting pipeline from the cleaning chamber to the circulating water pump.

[0103] In some embodiments, the control system 3 also monitors the current of the water electrolysis module 5 to determine whether the module is submerged in water by observing changes in current. For example, a current sensor may be configured to detect abnormally low current in the water electrolysis module, and the control system will automatically cut off the power supply to the module to avoid the risk of no-load operation.

[0104] In some embodiments, a cleaning chamber water level detection unit is also provided for detecting the water level inside the cleaning chamber.

[0105] In some embodiments, the control system confirms the water level in the cleaning chamber through a cleaning chamber water level detection unit, thereby controlling the liquid water level in the cleaning chamber accordingly.

[0106] For example, the electrolysis module is only allowed to operate when the water level exceeds the safe level, to avoid damage to the electrolysis module due to excessively low water levels.

[0107] For example, when electrically controlling the water injection in the cleaning chamber, the water level should be kept within the maximum value to avoid overfilling and causing overflow.

[0108] In some embodiments, the cleaning chamber water level detection unit includes a safety water level sensor 1051 for detecting the aforementioned safety water level. In some embodiments, the cleaning chamber water level detection unit includes a maximum water level sensor 1052 for detecting the highest water level.

[0109] In some embodiments, a cleaning chamber temperature detection unit 106 is also provided for detecting the temperature inside the cleaning chamber 101. The control system 3 can confirm the temperature inside the cleaning chamber 101 through the cleaning chamber temperature detection unit 106.

[0110] In some embodiments, the cleaning chamber temperature detection unit 106 includes an NTC temperature sensor.

[0111] In some embodiments, when the system includes a liquid supply pump 214, a water flow detection unit, an electric heater 215, and a cleaning chamber temperature detection unit 106, the control system 3 can control the temperature inside the cleaning chamber 101 to remain within a specified temperature range or above a specified temperature value.

[0112] For example, the control system first injects a high-temperature liquid or steam into the cleaning chamber to raise the temperature inside the chamber. Then, by controlling the steam supply (such as pausing steam supply when the temperature is high and resuming steam supply when the temperature drops), the temperature inside the cleaning chamber is maintained within the set temperature range or above the set temperature value to continuously clean or keep the stains dissolved by high temperature.

[0113] In some embodiments, the water level sensor (safe water level sensor and / or maximum water level sensor) of the cleaning chamber water level detection unit is a capacitive sensor.

[0114] In some embodiments, the temperature-sensing metal housing of the NTC temperature sensor is located inside the cleaning chamber, and the water level sensor of the cleaning chamber water level detection unit uses the temperature-sensing metal housing of the NTC temperature sensor for detection.

[0115] For example, the corresponding water level detection area has an NTC temperature sensor placed inside the cleaning chamber. The water level sensor of the cleaning chamber water level detection unit is a capacitive sensor, and the signal terminal of the capacitive sensor is electrically connected to the temperature-sensing metal housing of the NTC temperature sensor. When water comes into contact with the temperature-sensing metal housing of the NTC temperature sensor, the control system can detect that the water level has reached this height through the capacitive sensor. In this way, the water level sensor of the cleaning chamber water level detection unit does not need to be in direct contact with the water inside the cleaning chamber.

[0116] In some embodiments, the cleaning chamber temperature detection unit includes multiple NTC temperature sensors, which, together with the multiple water level sensors of the cleaning chamber water level detection unit, perform multi-point water level detection and multi-point temperature detection in the cleaning chamber.

[0117] For example, the cleaning chamber temperature detection unit includes a first NTC temperature sensor set in the safe water level detection area and a second NTC temperature sensor set in the highest water level detection area.

[0118] In some embodiments, the housing 1 has a receiving space, and an inner liner 107 is also provided inside the housing 1, the space inside the inner liner 107 forming a cleaning chamber 101.

[0119] In some embodiments, an air insulation space 108 is formed between the outer side of the inner liner 107 and the inner side of the casing 1, so that the heat of the inner liner 107 is not easily transferred to the casing 1.

[0120] In some embodiments, the baby bottle cleaning equipment further includes a drainage system 6, which is used to drain water or wastewater from the cleaning chamber 101.

[0121] In some embodiments, the drainage system 6 includes a drain pipe 601 through which water in the cleaning chamber 101 can be discharged.

[0122] In some embodiments, the drainage system 6 further includes a wastewater tank 602, through which water in the cleaning chamber 10 can be discharged to the wastewater tank 602 via a drain pipe 601.

[0123] In some embodiments, the drainage system 6 further includes an external drain pipe 603, through which water in the cleaning chamber 101 can be discharged to an external sewage collection point.

[0124] In some embodiments, the drainage system 6 includes a drain pipe 601, a sewage tank 602, and an external discharge pipe 603, which can drain water to the sewage tank and the outside.

[0125] In some embodiments, the drainage system further includes a second switching valve 604, which has at least three pipe interfaces and is capable of controlling at least one of the pipe interfaces to switch communication with the other two pipe interfaces. For example, the first end interface of the second switching valve can be controlled to switch communication with the second end interface and the third end interface of the second switching valve.

[0126] In some embodiments, the wastewater tank 602 has a wastewater discharge inlet 6021.

[0127] The second switching valve 604 is, for example, a three-way solenoid valve.

[0128] The first end of the second switching valve is connected to the drain pipe, the second end of the second switching valve is connected to the sewage inlet of the sewage tank, and the third end of the second switching valve is connected to the external discharge pipe.

[0129] The connection status of each end can be controlled by a three-way solenoid valve. For example, the first end interface of the second switching valve can be connected to the third end interface of the second switching valve, so that the water in the cleaning chamber can be discharged to the outside.

[0130] For example, connecting the first end interface of the second switching valve to the second end interface of the second switching valve allows the water in the cleaning chamber to be discharged into the sewage tank.

[0131] In some embodiments, the discharge system 6 further includes a drain pump 605, which is used to pump water in the cleaning chamber 101 to the drain pipe 601 to better discharge the water in the cleaning chamber 101.

[0132] In some embodiments, the outlet of the drain pump is connected to the drain pipe, and the inlet of the drain pump is connected to the cleaning chamber.

[0133] In some embodiments, the outlet of the drain pump 605 is connected to the drain pipe 601, and the inlet of the drain pump 605 is connected to the pumping channel of the circulating water pump 401.

[0134] The inlet of the drainage pump is connected to the cleaning chamber through the pumping channel of the circulating water pump. When draining, it can not only drain the water in the cleaning chamber, but also drain the residual water from the cleaning chamber to the circulating water pump, making the drainage cleaner.

[0135] In some embodiments, the drainage system further includes an air pump 606, the air outlet of which is connected to the water outlet of the drainage pump 605.

[0136] After the drainage pump 605 finishes pumping water, the sewage remaining in the drainage pipe can be discharged by the air pump 606 to better avoid sewage residue in the pipeline.

[0137] In some embodiments, an external discharge detection sensor is also provided at the discharge pipe. This sensor helps the control system confirm whether the discharge pipe is in a state where it can discharge water. This allows for accurate control over whether wastewater is discharged to the outside.

[0138] In some embodiments, when it is confirmed that the drain pipe is in a state where water cannot be discharged, the control system controls the cessation of external drainage or prohibits external drainage.

[0139] In some embodiments, when discharging wastewater from the cleaning chamber: if it is confirmed that the external drain pipe is in a state where water cannot be discharged, the control system controls to stop or prevent external drainage, and controls to drain water into the wastewater tank.

[0140] In some embodiments, the external discharge detection sensor is, for example, a proximity sensor, which can confirm the connection status when the water pipe of the external sewage collection container is connected to the external discharge pipe. This enables the control system of the bottle cleaning equipment to confirm that the external discharge pipe is in a state where water can be discharged, thereby accurately controlling whether the second switching valve switches to discharge water to the outside when draining.

[0141] In some embodiments, the external discharge detection sensor is, for example, a Hall sensor. Correspondingly, the external discharge pipe 603 is provided with a magnetic cover 608 or a magnetic plug that can be closed or screwed onto the external discharge pipe. When the magnetic cover 608 or the magnetic plug is removed, the external discharge pipe 603 is connected to the outside. At the same time, the control system can sense the movement of the magnetic cover 608 or the magnetic plug through the external discharge detection sensor, thereby confirming that the external discharge pipe 603 is in a state where drainage is possible.

[0142] In some embodiments, a sewage tank level sensor 609 is configured to detect the water level in the sewage tank 602.

[0143] The control system 3 can determine whether to drain water into the sewage tank 602 or whether to continue draining water into the sewage tank 602 based on the water level information detected by the sewage tank water level sensor 609.

[0144] For example, a non-contact water level sensor can be used for the wastewater tank. The water level sensor is mounted on the casing and detects the water level in the wastewater tank through indirect sensing.

[0145] Non-contact water level sensors include, for example, capacitive sensors.

[0146] In some embodiments, the specific settings of the wastewater tank level sensor can refer to the specific settings of the liquid storage tank level sensor, and be set as a corresponding multi-segment capacitive sensor. The difference is that this multi-segment capacitive sensor is used to detect the water level in the wastewater tank.

[0147] In some embodiments, when the water level in the sewage tank is detected to be at its maximum level, the system controls the cessation of drainage into the sewage tank.

[0148] In some embodiments, the wastewater tank 602 is detachably connected to the housing 1, so that the wastewater tank 602 can be removed from the housing 1 for easy cleaning of the wastewater tank and other operations.

[0149] In some embodiments, the housing has a wastewater tank receiving slot for accommodating a wastewater tank, and the wastewater tank is placed into the wastewater tank receiving slot from the slot opening of the wastewater tank receiving slot.

[0150] The sewage tank can be placed horizontally, vertically, or diagonally in the sewage tank receiving tank, or placed along a specified path or direction in the sewage tank receiving tank.

[0151] In some embodiments, the other side of the housing 1 has a sewage tank receiving groove 109 for accommodating a sewage tank, and the sewage tank 602 can be correspondingly inserted laterally into the sewage tank receiving groove 109.

[0152] In some embodiments, the wastewater tank and the liquid storage tank are respectively located on the left and right sides of the casing.

[0153] In some embodiments, the sewage inlet 6021 is located at the top of the sewage tank 602.

[0154] The second end interface of the second switching valve is located on the top wall of the sewage tank receiving tank, or extends to the top wall of the sewage tank receiving tank via a connecting pipe to form a sewage tank connection port 610.

[0155] Thus, the sewage inlet 6021 on the top of the sewage tank can correspond to the sewage tank connection port 610 on the casing after the sewage tank is snapped into place.

[0156] In some embodiments, the housing 1 is provided with a second positioning sensor 611 for detecting that the sewage tank is stuck in place.

[0157] The control system 3 uses the second positioning sensor 611 to confirm whether the sewage tank 602 is locked in place, thereby more accurately controlling whether to switch to draining water into the sewage tank.

[0158] In some embodiments, the second positioning sensor is, for example, a contact sensor such as a micro switch. When the sewage tank is inserted into position, the corresponding part on the sewage tank will press and trigger the contact of the micro switch, so that the control system can confirm that the sewage tank is inserted into position through the second positioning sensor.

[0159] In some embodiments, the second positioning sensor is a non-contact sensor such as a Hall sensor. When the sewage tank is inserted into position, the corresponding part on the sewage tank (such as a magnet installed on the sewage tank) is sensed by the Hall sensor to obtain a sensing trigger signal, so that the control system can confirm that the storage tank is inserted into position through the second positioning sensor.

[0160] In some embodiments, a second handle 612 is connected to the side of the sewage tank 602 that is exposed outside the sewage tank receiving slot, so that the user can conveniently pull the sewage tank 602 out of the sewage tank receiving slot 109 through the second handle 612.

[0161] In some embodiments, the top wall of the wastewater tank 109 forms a blocking mechanism against the top of the wastewater tank 602, so that the bottle cleaning device can be easily grabbed and lifted when it needs to be lifted.

[0162] In some embodiments, both the liquid storage tank and the wastewater tank are equipped with handles (a first handle and a second handle), and one side and the other side of the housing are opposite sides, such as one side of the housing being the left side and the other side being the right side. This allows for better force application when lifting the bottle cleaning device.

[0163] In some embodiments, the wastewater tank 602 may be made of a light-transmitting material, such as plastic or glass with good light transmittance, so that users can more easily see the water level or volume inside the tank from the outside.

[0164] In some embodiments, since the internal spatial shape of the wastewater tank and the storage tank remains unchanged, the water level change is related to the water volume. The control system also detects leaks using the water level signals detected by the wastewater tank water level sensor and the storage tank water level sensor.

[0165] For example, if the water level in the storage tank drops by x when the water is supplied to the cleaning chamber, the corresponding reduction in water volume is y; then after the water in the cleaning chamber is drained into the sewage tank, the rise in water level x1 in the sewage tank should be related to x, so that the increase in water volume y1 in the sewage tank is close to y.

[0166] For example, y1 not lower than yt is within the normal range, where t is the allowable water consumption.

[0167] When the detected water level change causes y1 to fall below yt, a leak is detected, and feedback can be provided through the information feedback module.

[0168] For example, a display screen is also provided to display feedback.

[0169] For example, a speaker is also installed to provide alarm feedback.

[0170] In some embodiments, if the wastewater tank and the liquid storage tank are of the same size and model, then x and x1 are the same.

[0171] In some embodiments, the baby bottle cleaning equipment further includes a drying system 7, which is used to deliver hot air into the cleaning chamber 101 so that the cleaned items can be dried quickly.

[0172] In some embodiments, the drying system 7 includes an air duct 701, a fan 702, and an air heater 703.

[0173] The air duct 701 is connected to the cleaning chamber 101. The fan 702 sends air into the cleaning chamber 101 through the air duct 701. The air heater 703 is used to heat the air sent into the cleaning chamber 101 to form hot air.

[0174] In some embodiments, the air heater includes a PTC heater disposed in the air duct.

[0175] In some embodiments, the drying system may deliver high-temperature hot air for high-temperature sterilization.

[0176] In some embodiments, the drying system 7 further includes a plasma generator 704, the plasma generated by the plasma generator 704 being sent into the cleaning chamber 101 along with the air.

[0177] In some embodiments, the plasma generator is disposed within the air duct.

[0178] In some embodiments, the housing 1 is provided with a protective door 110 corresponding to the item loading / unloading opening 102 of the cleaning chamber.

[0179] In some embodiments, the item loading / unloading opening can be located at the top of the cleaning chamber, and the protective door can also be located at the top of the casing.

[0180] In some embodiments, the protective door is mounted on the housing in a rotatable manner, meaning the protective door can be rotated open / rotated on.

[0181] For example, a hinge seat is provided on the top of the casing, and one side of the protective door is rotatably connected to the hinge seat.

[0182] In some embodiments, the protective door 110 is provided with a ventilation hole 111.

[0183] In some embodiments, the housing 1 is provided with a closing status sensor 112 for detecting the closing status of the protective door 110.

[0184] In some embodiments, the closing status sensor is, for example, a proximity sensor. After the protective door is closed in place, the proximity sensor detects the closing status and the control system confirms that the protective door is closed in place by using the closing status sensor.

[0185] In some embodiments, the closing status sensor is, for example, a Hall sensor. After the protective door is closed, it detects and senses a specific part (the part where a magnet is installed) on the protective door. The Hall sensor senses and detects the magnetic field of the magnet to provide a detection signal indicating that the door is closed. The control system confirms that the protective door is closed based on the obtained closing signal.

[0186] In some embodiments, the control system may perform corresponding control based on whether a closing signal is received.

[0187] For example, after confirming that the protective door is properly closed, the circulating water pump is allowed to pump water for cleaning or continue pumping water for cleaning; the fan is allowed to deliver hot air or continue delivering hot air; the steam is allowed to be delivered or continue delivering steam, etc., which are suitable controls that require the protective door to provide protection.

[0188] Correspondingly, for example, if it is confirmed that the protective door is not properly closed, it is prohibited to start or stop water cleaning, to start or stop hot air delivery, or to start or stop steam delivery.

[0189] In some embodiments, the housing 1 has a bottom shell 113. When installing internal components, the corresponding components (such as the aforementioned drying system, control system, electric heater, and other electrical components) can be installed into the housing 1 from the bottom of the housing 1, and then the bottom shell 113 can be installed, making installation more convenient.

[0190] In some embodiments, the baby bottle cleaning device is further provided with a control panel 114, through which corresponding control commands can be input. This control panel may include a "start / stop" button and other control buttons.

[0191] In some embodiments, the control system performs the following cleaning control method: Press the "Start / Stop" button to enter the washing state. The program first checks whether the liquid tank is installed properly through the sensor. If it is not installed properly, it will not start the operation. If the liquid tank is installed properly, it will check whether the water level in the liquid tank is 2L. If the water level is not sufficient, it will also check whether there is an external water inlet pipe. When there is an external water pipe, the first switching valve is opened to inject a certain amount of clean water into the storage tank from an external water source; during the water injection process, the water level sensor in the storage tank is used to detect the water level in the storage tank in real time, and if the maximum water level line is reached, the second switching valve is immediately closed. After the storage tank is filled with water, start the washing program (e.g., hot water wash → drain → hot water rinse → drain → hot water rinse → drain): The system first performs a hot water wash (e.g., hot water wash + drainage for 15 minutes). The water supply pump controls the flow rate to approximately 600 mL / min, injecting clean water into the electric heater. Simultaneously, the electric heater heats the water in the washing chamber to approximately 55°C. The temperature detection unit in the washing chamber monitors the water temperature in real time. If the temperature deviation exceeds 2°C, the water flow rate is adjusted to ensure the temperature remains within the required range. When the water level detection unit detects that the water level in the washing chamber has reached 900 mL, the electric heater and water supply pump are turned off. The circulating water pump is then started. During washing, the electrolysis water module is simultaneously activated, monitoring its operating current in real time. A temperature sensor monitors the temperature of the circulating water pump during the washing process; if the temperature exceeds the limit, the circulating water pump is shut off. After the washing time is complete, the circulating water pump and electrolysis water module are turned off to prepare for drainage. During drainage, the drainage pipe's drainage capability is first checked. If drainage is possible, the second switching valve is opened and the drainage pump is started; if drainage is not possible, the second switching valve is not opened. Next, check if a sewage tank is installed. If no sewage tank is installed, the drainage will not be started. If a sewage tank is installed, the drainage pump will be started to discharge sewage into the sewage tank through the drainage pipe. The sewage tank water level sensor will detect in real time whether the sewage tank water level has reached the maximum line. If the maximum line is reached, the drainage pump will be turned off.

[0192] The second hot water rinse (e.g., hot water rinse + drainage for 5 minutes) should not exceed 50℃. The process is the same as the first hot water wash.

[0193] The third hot water rinse (e.g., hot water rinse + draining for 9 minutes) has a maximum water temperature of approximately 70°C, and the process is repeated (as with the first hot water wash).

[0194] After washing, the system automatically enters steam sterilization (e.g., 10 minutes). Clean water is injected into the electric heater at a flow rate of approximately 98 mL / min. At the same time, the electric heater is turned on to inject 100°C water steam into the cleaning chamber for 10 minutes. During this process, the water level in the storage tank is monitored in real time. If the water level is lower than the minimum water level, a water shortage alarm is triggered. The heater temperature sensor on the electric heater monitors the temperature of the electric heater in real time. If the temperature exceeds 110°C, heating is stopped.

[0195] After steam sterilization is completed and the water in the cleaning chamber is drained, the drying process (e.g., 60 minutes) automatically begins. The air heater and fan work simultaneously, and the plasma module is also turned on. During the drying process, the temperature in the cleaning chamber is monitored in real time. When the temperature in the cleaning chamber is higher than 70°C, the air heater is turned off; when it is lower than 60°C, the air heater is turned on.

[0196] Once drying is complete, the machine will automatically transfer to storage (e.g., 72 hours) while maintaining the temperature inside the cleaning chamber at 60°C.

[0197] In some embodiments, the water electrolysis module is not activated during the last washing cycle. For example, during the third hot water rinse described above, the water electrolysis module is not activated to reduce residual electrolyzed water.

[0198] In some embodiments, when applying the solid part of the cleaning chamber, it can be understood as applying the solid part on the housing; or when there is an inner liner, it can be understood as applying the solid part on the inner liner.

[0199] In one embodiment, to facilitate space arrangement and pipe installation, the pipes can be extended and connected by adding connecting pipes, or directly connected. The connection between the above-mentioned pipes can be understood as enabling water to flow between them.

[0200] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
