Description

Technical Field

[0001] This disclosure relates to the field of water dispenser technology, and more particularly to a water purifier. Background Technology

[0002] To prevent users from being scalded, existing water purifiers typically use voice prompts to warn of burns, add an unlock button to control the hot water dispensing button (with multi-layer protection), or adjust the water temperature below the actual set value to reduce the risk of scalding. When using a water purifier, users usually place the cup on the countertop. The water flow is consistent throughout the process, and when hot water is dispensed, it can easily splash out of the cup. Furthermore, sometimes users forget to turn off the water after pressing the hot water button, causing the cup to become too full or overflow, resulting in the cup and handle becoming overheated and potentially causing burns.

[0022] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0023] like Figures 1-2 As shown in the illustration, this disclosure provides a water purifier that filters water from a water source and may or may not heat the filtered water. The water source may be tap water or water contained in a storage container.

[0024] The water purifier includes at least one water outlet. Optionally, the water purifier includes one or two water outlets. In the example of two water outlets, one of the two water outlets is used to dispense hot water and the other is used to dispense room temperature water. The two water outlets respectively constitute a hot water outlet and a room temperature water outlet.

[0025] The water purifier includes a placement part 1, a laser scanning component 2, and a control unit. The placement part 1 is used to support the water intake container. Optionally, the placement part 1 can be a support plate, a support perforated plate, a support mesh plate, or a support frame.

[0026] The laser scanning component 2 is used to detect the height, depth, and water level of the water intake container.

[0027] The water outlet section includes an interconnected water outlet chamber and a water outlet 3. Room temperature water or hot water flows out of the water purifier sequentially through the water outlet chamber and the water outlet 3. The water outlet section further includes a pressure adjustment section for adjusting the pressure in the water outlet chamber. Optionally, the pressure adjustment section is used to at least increase the pressure in the water outlet chamber, thereby increasing the water outlet speed.

[0028] The control unit is configured to generate a first water outlet control command when the water level in the water intake container is lower than a first preset water level. The first water outlet control command is used to control the pressure adjustment unit to apply pressure to the water outlet chamber. Thus, when the water volume in the water intake container is low, the pressure in the water outlet chamber can be increased by the pressure adjustment unit, thereby improving the water outlet speed.

[0029] Optionally, the control unit is configured such that when the water level in the water intake container is lower than the first preset water level, the water level in the water intake container is low and the water volume is small, the first water outlet control command is also used to control the water outlet speed of the water outlet to a first water outlet speed, so that the water outlet outlet outlets water at a higher water outlet speed.

[0030] Optionally, the control unit is configured to generate a second water outlet control command when the water level in the water intake container is greater than or equal to a first preset water level and less than a second preset water level. The second water outlet control command is used to control the pressure adjustment unit to stop applying pressure to the water outlet chamber.

[0031] Specifically, the second preset water level is higher than the first preset water level. For example, the second preset water level can be the highest water level in the water intake container, and the water depth h1 corresponding to the first preset water level is 70%-95% of the water depth h2 corresponding to the second preset water level, such as 80%, 85% or 90%.

[0032] Optionally, the second preset water level is determined based on the depth of the water intake container, and the first preset water level is determined based on either the depth of the water intake container or the second preset water level.

[0033] In an alternative example, the laser scanning component 2 is also used to detect the shape and size parameters of the water container. The second preset water level is determined based on the user's operation instructions and the shape and size parameters of the water container. The operation instructions carry specified water output information, which is used to indicate the water output corresponding to the user's input operation.

[0034] When the water level in the water intake container is greater than or equal to the first preset water level, the water volume in the water intake container is relatively large. The second water outlet control command is used to control the pressure adjustment unit to stop applying pressure to the water outlet chamber, so as to avoid water splashing out of the water intake container due to excessive water outlet speed.

[0035] Optionally, the second water outlet control command is also used to control the water outlet speed of the water outlet section to a second water outlet speed, wherein the second water outlet speed is less than the first water outlet speed, so that the water outlet section outlets water at a lower water outlet speed.

[0036] Optionally, the control unit is further configured to generate a stop water discharge command when the water level in the water intake container is greater than or equal to a second preset water level, thereby controlling the water outlet to stop discharging water.

[0037] In an optional embodiment, the water outlet section includes a water outlet cavity 30, a connecting cavity, and a water outlet 3 connected in sequence. The water outlet cavity 30 includes a water inlet 31 and a side wall 33. The water inlet 31 is located at the bottom of the side wall 33 or on the bottom wall of the water outlet cavity, and a water inlet pipe 32 is connected to the water inlet 31.

[0038] The pressure adjustment unit is provided in the water outlet chamber 30. The pressure adjustment unit includes a movable body 35, which is constructed as a piston or a flat plate. The movable body 35 is sealed relative to the side wall 33. Specifically, the side of the movable body 35 is sealed to the side wall 33. The movable body 35 forms the top wall of the water outlet chamber 30. The movable body 35 can move along the side wall 33, for example, reciprocating, thereby changing the volume of the water outlet chamber 30 to increase or decrease the pressure in the water outlet chamber 30. This allows for increasing the water outlet speed during water discharge by increasing the pressure in the water outlet chamber 30, and also allows for backflow of water from the outlet 3 by decreasing the pressure in the water outlet chamber 30 after water discharge has stopped.

[0039] Optionally, the sidewall 33 is a cylindrical sidewall, and the movable body 35 is capable of reciprocating along the axial direction of the cylindrical sidewall.

[0040] In an optional embodiment, the pressure adjustment unit includes a drive unit for moving the movable body 35 along the side wall 33.

[0041] Optionally, the movable body 35 is fixedly connected to a permanent magnet (not shown), and the driving unit includes an electromagnetic driving assembly 37, which is used to generate a magnetic field or not generate a magnet, see [link to relevant documentation]. Figure 2 By controlling the magnetic field generated by the electromagnetic drive component 37, the electromagnetic drive component 37 and the permanent magnet attract or repel each other, thereby driving the movable body 35 to move in the desired direction.

[0042] In an alternative embodiment, the sidewall 33 has an end wall at its top, and a pressure medium cavity is provided between the end wall and the movable body 35. The movable body 35 is moved in a desired direction by filling or discharging pressure medium into or from the pressure medium cavity. The pressure medium can be air, and the pressure medium cavity is connected to an air pump, which is used to supply air to or discharge air from the pressure medium cavity.

[0043] For example, the movable body 35 is fixedly connected to the drive piston, the drive piston is located between the movable body 35 and the end wall, and the pressure medium cavity is formed between the drive piston and the end wall. By supplying air to the pressure medium cavity or discharging air from the pressure medium cavity, the drive piston moves and drives the movable body 35 to move.

[0044] In an optional embodiment, the pressure adjustment unit includes a piston body 36 fixedly disposed relative to the movable body 35. The piston body 36 is fixedly connected to the movable body 35 via a connecting shaft 4 or a connecting rod, and the piston body 36 is located in the communicating cavity.

[0045] The inlet end of the connecting cavity is connected to the outlet cavity 30. The inlet end is provided with a sealing mating part. The piston body 36 includes a sealing body adapted to the sealing mating part, and the sealing body can make sealing contact with the sealing mating part. Thus, after the water discharge is completed, the movable body 35 and the piston body 36 can be controlled to move upward, so that the sealing body of the piston body 36 contacts the sealing mating part at the inlet end, and a seal is formed between the sealing body and the sealing mating part.

[0046] In an optional implementation, the laser scanning component 2 is used to detect a preset object, which can be a human hand or other movable object other than a water container.

[0047] The control unit is configured to generate a stop water dispensing command when the laser scanning component 2 detects the presence of a preset object. This stop water dispensing command controls the water purifier to stop dispensing water, preferably stopping the dispensing of hot water. Therefore, during the water dispensing process, at least when a human hand is detected, the dispensing of hot water can be stopped, preventing scalding of the user's hand.

[0048] In an optional embodiment, the laser scanning component 2 is disposed near the water outlet 3 of the water outlet section, and the laser scanning component 2 is used to scan a preset spatial area.

[0049] For example, the water purifier includes two water outlets, one of which is used to dispense hot water and the other is used to dispense room temperature water. A laser scanning component 2 is located between the water outlets 3 of the two water outlets and is used to scan a preset spatial area.

[0050] In an optional embodiment, the placement part 1 includes a placement area corresponding to the water outlet 3. The placement area is used to support the water taking container, and the water taking container located in the placement area can receive water from the water outlet 3 corresponding to the placement area.

[0051] The placement area is equipped with a weight sensor 5, which is used to detect the weight of the water container. The control unit is configured to generate a stop-discharge command when the weight of the water container meets a preset overflow condition. This stop-discharge command controls the water purifier to stop discharging water. Specifically, the stop-discharge command is generated when the weight of the water container no longer changes or fluctuates, thereby preventing overflow caused by malfunctions of some components of the water purifier.

[0052] In an optional embodiment, the placement unit 1 includes a placement area corresponding to the water outlet 3, and the water purifier further includes a projection lamp 6 for illuminating the placement area. Thus, the projection lamp 6 illuminates the placement area to indicate the user's desired placement location for the water container.

[0053] In an optional embodiment, the placement unit 1 includes a hot water outlet placement area and a room temperature water outlet placement area corresponding to the water outlet 3. The water purifier also includes a first projection lamp and a second projection lamp. The first projection lamp illuminates the hot water outlet placement area, and the second projection lamp illuminates the room temperature water outlet placement area. The color of light emitted by the first projection lamp and the color of light emitted by the second projection lamp are different. For example, the color of light emitted by the first projection lamp is red, and the color of light emitted by the second projection lamp is blue or green. Thus, the different colors of light from the projection lamps indicate to the user the placement location of the water container corresponding to different water temperatures.
