Description
Technical Field
[0001] This utility model relates to the field of pure water machine technology, specifically to a wastewater transfer component and a laboratory pure water machine. Background Technology
[0002] A pure water machine is a water purification device that uses multi-stage filter cartridges to purify water. It uses physical methods such as filtration, adsorption, and reverse osmosis without adding chemicals to remove or reduce salts in the water to a certain level. Laboratory pure water machines generally use tap water to produce pure water and discharge wastewater into a laboratory water tank through pipes. For example, Chinese Patent 202411585459.2 discloses a monitoring method and storage device for preventing water quality deterioration in a laboratory pure water tank. The storage device includes a pure water tank, and the bottom of the pure water tank is provided with an inlet, an outlet, and a drain port that communicate with the inner cavity of the pure water tank.
[0003] The inlet of a laboratory pure water machine is usually connected to the tap water supply through a pipe, while the outlet is usually guided to the laboratory water tank through a wastewater pipe. However, during operation, it often happens that the experimenter forgets to put the wastewater pipe into the water tank, resulting in wastewater being discharged onto the experimental table when the pure water preparation equipment is in use. Utility Model Content
[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a wastewater transfer component to solve the technical problem that often occurs in the operation of existing technology, where the experimental operator forgets to put the wastewater pipe into the water tank, resulting in wastewater being discharged onto the experimental platform when using pure water preparation equipment.
[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0006] In a first aspect, this utility model provides a wastewater transfer component, comprising:
[0007] Wastewater tank, which is equipped with an inlet and a drain pipe;
[0008] A liquid level sensing component, which is installed inside the wastewater tank, is used to detect the liquid level height;
[0009] A pressure-sensitive feedback component having a clamping end for clamping the drain tube and providing a pressure-sensitive signal;
[0010] The on / off component has a connection end for connecting to the liquid inlet of the water purifier to switch the liquid inlet of the water purifier on and off.
[0011] An active start component, mounted on the drain pipe, has a press-button end for pressing to activate the on / off switch to the inlet path; and
[0012] The controller is electrically connected to the level sensing component, pressure feedback component, active start component, and on / off component.
[0013] In some embodiments, the level sensing component includes a level sensor installed on the inner wall of the wastewater tank for providing feedback on the wastewater warning level.
[0014] In some embodiments, the pressure feedback assembly includes an elastic clip and a pressure sensor. The pressure sensor is mounted inside the elastic clip, and the tail end of the drain pipe is clipped inside the elastic clip and abuts against the pressure sensor. The pressure sensor is used to detect whether the drain pipe is clipped inside the elastic clip.
[0015] In some embodiments, the on / off component includes a solenoid valve and a connecting pipe. The solenoid valve is mounted on the connecting pipe and is electrically connected to the controller. The controller controls the solenoid valve to switch between opening and closing based on feedback signals from the pressure feedback component, the liquid level sensing component, and the active start component.
[0016] In some embodiments, the top of the wastewater tank has an opening, a shelf is inserted into the opening, and a drain hole is provided on the shelf.
[0017] In some embodiments, a receiving groove is provided on the side wall of the wastewater tank, and the drain pipe is inserted into the receiving groove.
[0018] In some embodiments, the receiving groove includes an L-shaped groove and an annular groove, the L-shaped groove is tangent to the annular groove, and the depth of the annular groove is greater than the depth of the L-shaped groove. The depth of the L-shaped groove matches the depth of the drain pipe, and the annular groove is used to wind around the drain pipe.
[0019] In some embodiments, the pressure feedback component is mounted at the top of the L-shaped groove.
[0020] In some embodiments, the active start component includes a mounting bracket and a push-button switch, the mounting bracket being fixed to the outside of the drain pipe and the push-button switch being mounted on the mounting bracket.
[0021] Secondly, this utility model also provides a laboratory pure water machine, including the wastewater transfer component described in any one of the above.
[0022] Compared with the prior art, the wastewater transfer component provided by this utility model requires the active activation component to press the on / off component to open the water inlet passage of the pure water machine, reminding personnel to pay attention to the arrangement of the drain pipe, which can effectively avoid forgetting to put the drain pipe into the laboratory water tank; the pressure feedback component provides position feedback of the drain pipe, and together with the liquid level sensing component, when the wastewater level is too high, the on / off component cuts off the water supply of the pure water machine, interrupting the pure water preparation, and preventing wastewater overflow caused by the continued preparation of pure water when personnel forget to turn off the pure water preparation process.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0031] To address the common problem of operators forgetting to place the wastewater pipe into the water tank during pure water preparation, resulting in wastewater overflowing onto the lab bench, this invention provides a wastewater transfer component. This component allows for active activation of the on / off switch to open the water inlet to the pure water machine, reminding operators to pay attention to the drain pipe's placement and effectively preventing forgetting to place it in the laboratory water tank. When the drain pipe is not in use and only a small amount of pure water is being prepared, a pressure-sensitive feedback component provides positional feedback for the drain pipe, activating a level sensor component to match the situation. When only the wastewater tank is used to store wastewater, the on / off switch can cut off the water supply to the pure water machine if the wastewater level is too high, thus stopping pure water preparation and preventing wastewater overflow caused by continued pure water preparation when operators forget to turn it off.
[0032] It should be noted that the wastewater transfer component described in this utility model is used in, but not limited to, pure water machines. For ease of explanation, this utility model only uses the application of the wastewater transfer component in a pure water machine as an example. The principle of the wastewater transfer component in other types of equipment is essentially the same as that in pure water machines, and will not be described in detail here.
[0033] Please see Figure 1-5This utility model provides a wastewater transfer component, which includes a wastewater tank 1, a liquid level sensing component 2, a pressure feedback component 3, an on / off component 4, an active start component 5, and a controller 6. Wastewater tank 1 is equipped with an inlet 101 and a drain pipe 102. The inlet 101 is connected to the wastewater outlet of the pure water machine 7 via a pipe, and the drain pipe 102 is connected to the bottom side of the wastewater tank 1 to discharge the liquid in the wastewater tank. A liquid level sensing component 2 is installed inside the wastewater tank 1 to detect the liquid level. In the case where wastewater is only stored in the wastewater tank 1, the liquid level sensing component 2 monitors whether the warning level has been reached to prevent the wastewater from overflowing. A pressure feedback component 3 has a clamping end for clamping the drain pipe 102 and providing a pressure signal. The pressure feedback component 3 clamps and positions the drain pipe 102, and when positioned, it can generate a signal feedback that the drain pipe 102 has not been removed for use. A switch component 4 has a connection end for connecting to the inlet of the pure water machine to switch the pure water machine's liquid inlet on and off. The switching and on / off component 4 is directly installed at the water inlet of the pure water machine to control the water inlet flow. When the water inlet is cut off, the pure water preparation process is interrupted. The active start component 5 is installed on the drain pipe 102 and has a press end for pressing to activate the on / off component 4 to switch to the liquid inlet path. The active start component 5, the pressure feedback component 3, and the liquid level sensor component 2 form a multi-level control system for on / off operation, with the active start component 5 having the highest priority. Each time pure water is prepared, if the on / off component 4 needs to be activated to supply water, the active start component 5 must be pressed to open the path of the on / off component 4. This structure effectively prevents operators from forgetting to put the drain pipe 102 into the water tank. The controller 6 is electrically connected to the liquid level sensor component 2, the pressure feedback component 3, the active start component 5, and the on / off component 4.
[0034] It should be noted that controller 6 uses a programmable logic controller (PLC), and its electrical connection method and control method can adopt conventional control methods of existing technology.
[0035] In this embodiment, the on / off component 4 is in the normally open state. When the drain pipe 102 is not used for draining and the component is not stored in the pressure feedback component 3 for clamping, it can provide a pressure signal to the controller 6. When there is a pressure signal, the controller 6 maintains the normally open state of the on / off component 4. Conversely, when the drain pipe 102 is disengaged from the pressure feedback component 3 and loses the pressure signal, the controller 6 switches the on / off component 4 to the normally closed state.
[0036] Furthermore, when the on / off component 4 is in the normally open state, the controller 6 monitors the liquid level signal of the liquid level sensor component 2 in real time. The liquid level sensor component 2 detects the liquid level height in the wastewater tank 1. When the liquid level is too high, the controller 6 controls the on / off component 4 to switch to the off state according to the feedback liquid level warning height signal, and blocks the tap water supply to the pure water machine to avoid wastewater overflow.
[0037] Furthermore, when the on / off component 4 is normally closed, the drain pipe 102 is disconnected from the pressure feedback component 3. Therefore, the component 5 needs to be actively activated by pressing the signal. Only when the controller 6 receives the pressing signal will it switch to the path of the on / off component 4 to connect the tap water supply of the pure water machine, so as to avoid forgetting to arrange the position of the drain pipe 102.
[0038] Furthermore, when the drain pipe 102 is arranged and the on / off component 4 is opened, a single pure water preparation is performed. After preparation, the liquid level sensing component 2 detects the liquid level in the wastewater tank 1. When the liquid level drops below the set height, which is generally set to the zero liquid level of basic emptying, the controller 6 switches the on / off component 4 back to the normally closed state to switch the on / off state for a single pure water preparation. This ensures that the next pure water preparation requires pressing the active start component 5 again, avoiding the situation where the drain pipe 102 is not retracted to the pressure feedback component 3 after pure water preparation.
[0039] In one embodiment, please refer to Figure 4 The liquid level sensing component 2 includes a liquid level sensor 21, which is installed on the inner wall of the wastewater tank 1 and is used to provide feedback on the wastewater warning level.
[0040] Among them, the liquid level sensor 21 adopts a liquid level switch, which is installed at the upper warning water level and the lower drain water level respectively, to detect the high water level of the warning and the low water level of the drainable water level, thereby providing feedback on the water level height.
[0041] Understandably, the liquid level sensor 21 can be a float type, a capacitive type, or the like, as long as it achieves the effect of liquid level monitoring.
[0042] It should be noted that the liquid level sensor 21 can also be an ultrasonic liquid level sensor, which emits high-frequency sound waves of 20kHz~200kHz through a piezoelectric transducer. The sound waves are reflected by the liquid surface, and the receiver calculates the time difference between the emission and the echo to convert it into the liquid level height.
[0043] In one embodiment, please refer to Figure 1 and Figure 2 In order to position the drain pipe 102, the pressure feedback assembly 3 includes an elastic clamp 31 and a pressure sensor. The pressure sensor is installed inside the elastic clamp 31. The tail end of the drain pipe 102 is clamped inside the elastic clamp 31 and abuts against the pressure sensor. The pressure sensor is used to detect whether the drain pipe 102 is clamped inside the elastic clamp 31. When the tail end of the drain pipe 102 is clamped inside the elastic clamp 31, the pressure sensor abuts against the drain pipe 102, forming pressure feedback.
[0044] Furthermore, in order to facilitate the storage of the drain pipe 102 in conjunction with the pressure feedback component 3, a storage groove 105 is provided on the side wall of the wastewater tank 1, and the drain pipe 102 is inserted into the storage groove 105.
[0045] Specifically, the storage slot 105 includes an L-shaped slot 105a and an annular slot 105b. The L-shaped slot 105a and the annular slot 105b are tangent, meaning that the horizontal part of the L-shaped slot 105a is horizontally cut to the bottom of the annular slot 105b, and the vertical part of the L-shaped slot 105a is vertically cut to one side of the annular slot 105b. The drain pipe 102 is connected to the wastewater tank 1 at its bottom end, inserted from the horizontal part of the L-shaped slot 105a, wound around the annular slot 105b, and finally inserted upward from the vertical part of the L-shaped slot 105a, and snapped into the inner side of the elastic clip 31 of the pressure feedback component 3. The pressure feedback component 3 is installed at the top of the L-shaped slot 105a, that is, at the top of the vertical part of the L-shaped slot 105a.
[0046] The annular groove 105b has a greater depth than the L-shaped groove 105a. The annular groove 105b is used to wind the drain pipe 102, allowing the drain pipe 102 to be wound at least one turn. The depth of the L-shaped groove 105a matches the depth of the drain pipe 102, allowing the drain pipe 102 to be inserted.
[0047] In one embodiment, please refer to Figure 1 To prevent pure water from overflowing onto the experimental table, the top of the wastewater tank 1 is provided with an opening 103, and a shelf 104 is inserted into the opening 103. The shelf 104 is provided with a drain hole 104a.
[0048] Understandably, if the experimenter sets up the drain pipe 102 to introduce wastewater into the water tank, but forgets the pure water preparation time, resulting in the container being full of pure water and overflowing, the overflowing pure water can be introduced into the wastewater tank 1 through the drain hole 104a. In addition, with the liquid level sensing component 2, the tap water supply is turned off when the wastewater tank 1 reaches the warning water level, thereby preventing pure water from overflowing onto the experimental table.
[0049] Understandably, the warning water level setting of wastewater tank 1 is designed to allow for a capacity greater than the total volume of pure water and wastewater that will continue to be discharged after the water source is cut off, i.e., the total volume of pure water and wastewater that may continue to be generated inside the water purifier after the water source is cut off.
[0050] In one embodiment, please refer to Figure 3For on / off control, the on / off component 4 includes a solenoid valve 41 and a connecting pipe 42. The solenoid valve 41 is mounted on the connecting pipe 42, one end of which is connected to the water inlet of the water purifier, and the other end is connected to the tap water supply pipe. The solenoid valve 41 is electrically connected to the controller 6. The controller 6 controls the solenoid valve 41 to switch between opening and closing based on feedback signals from the pressure feedback component 3, the liquid level sensing component 2, and the active start component 5.
[0051] The on / off component 4 is connected to the wastewater tank 1 via a connector 401. The connector 401 can be a bracket, which is a structural component that connects the solenoid valve 41 and the connecting pipe 42 to the wastewater tank 1.
[0052] Understandably, connector 401 can also simply use a cable to connect solenoid valve 41 and connecting pipe 42 to wastewater tank 1, and connect them to controller 6 via cable.
[0053] In one embodiment, please refer to Figure 2 To facilitate press control, the active start component 5 includes a mounting bracket 51 and a push-button switch 52. The mounting bracket 51 is fixed to the outside of the drain pipe 102, and the push-button switch 52 is mounted on the mounting bracket 51. The mounting bracket 51 is convex to facilitate gripping. Pressing the push-button switch 52 once provides an activation signal and resets.
[0054] It should be noted that the electrical connections between the controller 6 and the solenoid valve 41, the level sensor 21, the pressure sensor, and the push-button switch 52 can all be made via wires. The entire device can be powered by an external power supply or a built-in battery.
[0055] This utility model also provides a laboratory pure water machine, including the wastewater transfer component described in any of the above. The pure water machine is detachably installed on the top of the wastewater transfer component. The wastewater tank 1 can be separated from the pure water machine 7, and the wastewater tank 1 can be cleaned or emptied separately. To empty the water, the shelf 104 is removed, and the water is poured out through the outlet 103.
[0056] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
