Detailed Implementation
[0029] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.
[0030] As a specific embodiment, the tea tray drainage device of this utility model includes a carrier 1, a water pump 2, an air valve 3, and an electrical control device 8 electrically connected to the water pump 2. The electrical control device 8 is a circuit board or the like in the prior art, which can control parameters such as the start, stop, and running speed of the water pump 2.
[0031] Carrier 1 is used to be positioned below the tea tray (not shown in the attached diagram).
[0032] The carrier 1 is provided with a terminal drain outlet 19, a sealing cavity 12, and a tea tray connection port 11 for communicating with a tea tray (not shown in the attached figure).
[0033] The water pump 2 is provided with a water pump inlet 21 and a water pump outlet 22 that communicates with the terminal drain outlet 19. It is easy to understand that when the water pump 2 is started, water flows into the water pump 2 from the water pump inlet 21 and flows out of the water pump 2 from the water pump outlet 22. The terminal drain outlet 19 is typically a quick-connect interface to facilitate connection of a hose to the terminal drain outlet 19.
[0034] The tea tray connection port 11, one end of the air valve 3, and the water pump inlet 21 are respectively connected to the sealing cavity 12. It is easy to understand that when the air valve 3 is open, the air valve 3 allows the sealing cavity 12 to communicate with the atmosphere, and when the sealing cavity 12 is closed, the sealing cavity 12 cannot communicate with the atmosphere.
[0035] The water pump 2 is a peristaltic pump (i.e., in the prior art, a power device that delivers fluid by squeezing an elastic hose, and its working principle is similar to the peristalsis of the digestive tract; the device is driven by a motor to continuously squeeze the hose to form a vacuum to draw in fluid) or a diaphragm pump.
[0036] The start and stop of the water pump 2 and the opening and closing of the air valve 3 are both configured to be controlled according to the amount of water in the sealed cavity 12 (i.e., the amount of tea residue water described later).
[0037] The working principle is as follows: before use, connect the tea tray connection port 11 to the tea tray. It is easy to understand that with the use of the tea tray, wastewater and tea residue will usually be generated on the tea tray (hereinafter referred to as tea residue water); the tea residue water can flow to the tea tray connection port 11 through the delivery pipe (not shown in the attached figure).
[0038] When the water level in the sealed chamber 12 falls below the water threshold (i.e., the set threshold for tea residue water, which is usually a fixed value stored in the electronic control device 8. This value can be adjusted through program settings, physical knobs, etc.), the air valve 3 opens and the water pump 2 stops. At this time, the sealed chamber 12 is connected to the atmosphere through the air valve 3, and the tea residue water on the tea tray can flow into the sealed chamber 12 by its own weight. It is easy to understand that during this process, the water level in the sealed chamber 12 will increase and gradually approach the water threshold.
[0039] When the water level in the sealed cavity 12 is higher than or equal to the water level threshold, the air valve 3 closes and the water pump 2 starts. At this time, the water pump 2 causes the tea residue water to be transported from the sealed cavity 12 to the terminal drain outlet 19, and then from the terminal drain outlet 19 to other locations, such as a wastewater tank, through pipes. Simultaneously, the sealed cavity 12 cannot be connected to the atmosphere through the air valve 3; therefore, the pipe connecting the tea tray to the tea tray connection port 11 is the channel connecting the sealed cavity 12 to the atmosphere. The start of the water pump 2 also accelerates the pumping of tea residue water from the tea tray into the sealed cavity 12. It is easy to understand that during this process, the water level in the sealed cavity 12 will decrease until it falls below the water level threshold. Typically, the electrical control device 8 is also electrically connected to an operating device 82 for manual control of the water pump 2, etc.
[0040] Repeating the above process can automatically remove tea residue and water from the tea tray, and the short operating time of the water pump 2 can reduce the duration of noise and save energy.
[0041] As one specific implementation method, when the water level in the sealed cavity 12 is controlled below the water level threshold, the air valve 3 closes and the water pump 2 starts and remains in operation for a specified period. After this period, the air valve 3 opens and the water pump 2 starts and stops. This implementation method ensures that all tea residue water in the pipe connecting the tea tray and the tea tray connection port 11 enters the sealed cavity 12.
[0042] As one specific implementation method, the air valve 3 is an electrically controlled valve and is electrically connected to the electrically controlled device 8.
[0043] As one specific implementation, a sensor for detecting the water level in the sealed cavity 12 is also included. This sensor is electrically connected to the electronic control device 8 and includes one or more of a water level sensor 81 and a weight sensor. For example, the water level sensor 81 is a prior art sensor for detecting water levels; it extends into the sealed cavity 12 and detects the water level of the tea residue water within the sealed cavity 12 by detecting the height of the water. Alternatively, the weight sensor is located at the bottom of the carrier 1 and detects the water level of the tea residue water in the sealed cavity 12 by detecting the weight of the carrier 1 and tare it. Of course, the water level sensor 81 and the weight sensor can also be used simultaneously.
[0044] As one specific implementation, the carrier 1 includes a sealing cavity cover 122, a carrier component 13, and a carrier cover 14 covering the top opening of the carrier component 13; the bottom wall of the carrier component 13 is provided with a sealing cavity sidewall 121, and the sealing cavity cover 122 covers the top opening of the sealing cavity sidewall 121; the carrier cover 14 and the sealing cavity cover 122 are detachably and fixedly connected to the carrier component 13 by means of screw posts 4 and lugs 41, and the direction of the screw posts 4 is from the carrier cover 14 to the sealing cavity 12; at least one of the air valve 3, the water pump 2, and the electrical control device 8 is fixedly disposed on the top surface of the sealing cavity cover 122. Of course, the electrical control device 8 can also be disposed on the bottom surface of the carrier cover 14. The sealing cavity cover 122, which is fixed with the air valve 3 and the water pump 2, is placed on the top of the sealing cavity side wall 121. Then, through the top opening of the carrier component 13, a screwdriver or similar tool is used to screw the screw on the carrier cover 14, which points towards the sealing cavity 12, through the lug 41 and into the screw post 4, thus achieving a detachable and fixed connection between the sealing cavity cover 122 and the carrier component 13. Then, the carrier cover 14 is fixedly connected to the carrier component 13, which facilitates assembly and ensures the sealing performance of the sealing cavity 12. It should be noted that the lug 41 refers to the part through which the screw passes, not just a protruding part.
[0045] As one specific implementation, the carrier component 13 is provided with a carrier cover rigid tube 111; the sealing cavity cover 122 is provided with a sealing cavity rigid tube 112; the carrier cover rigid tube 111 and the sealing cavity rigid tube 112 are connected by a flexible tube, and the carrier cover rigid tube 111 is inserted, threaded, or snapped into the flexible tube. Of course, the sealing cavity rigid tube 112 can also be inserted, threaded, or snapped into the flexible tube. Under the premise of the above implementation, after the sealing cavity cover 122 is fixed, it is convenient to insert, thread, or snap the other end of the flexible tube into the movable carrier cover rigid tube 111. Afterwards, when the carrier cover 14 is fixedly connected to the carrier component 13, the flexible tube will not interfere with the installation of the carrier cover 14. In summary, this implementation can conveniently complete the assembly of the carrier cover 14.
[0046] As one specific implementation method, the tea tray drainage device of this utility model has one of the following features: a rigid air valve pipe 31 is provided on the sealing cavity cover 122, and the air valve 3 is connected to the air valve pipe 31 through a hose; a rigid sealing cavity water pump pipe 211 is provided on the sealing cavity cover 122, and the water pump inlet 21 is connected to the sealing cavity water pump pipe 211 through a hose; the terminal drain outlet 19 is a quick interface and is fixed on the sealing cavity cover 122, and the water pump outlet 22 is connected to the terminal drain outlet 19 through a hose.
[0047] As one specific implementation, the bottom wall of the sealing cavity 12 is recessed to form a sealing cavity recess 125. A sealing cavity water suction pipe 211 extends into the sealing cavity 12, with the pipe facing directly towards the recess 125 and the bottom end of the recess 125 close to it, or the bottom end of the recess 125 is sloped and in contact with it. This ensures that the tea residue water in the sealing cavity 12 is completely pumped out by the water pump 2. The sloped bottom end of the recess 125 in contact with it reduces or eliminates noise generated when the tea residue water in the sealing cavity 12 is nearly completely pumped out. Typically, the carrier member 13 is provided with support feet 139 to accommodate the space required for the sealing cavity recess 125.
[0048] As one specific embodiment, a sealing ring 123 is provided between the top of the sealing cavity cover 122 and the top of the sealing cavity sidewall 121. A sealing ring groove 124 is provided on the top of the sealing cavity cover 122 or the sealing cavity sidewall 121, and the sealing ring 123 is embedded in the sealing ring groove 124. This embodiment can improve the sealing performance between the top of the sealing cavity cover 122 and the top of the sealing cavity sidewall 121.
[0049] The terms used in this invention, such as "first," "second," etc., do not indicate any order, quantity, or importance, but are merely for distinction.
[0050] In this invention, terms such as "a" or "an" are used to indicate not a limitation on the quantity, but rather to indicate the existence of at least one of the mentioned objects.
[0051] In this utility model, terms indicating direction or location such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, and below are used to indicate relative positions rather than absolute positions.
[0052] Terms used in this invention, such as "approximately," "generally," "approximately," and "similar," are limiting terms used to indicate features that are present but allow for certain deviations. The amount of deviation allowed may vary depending on the specific context; for example, regarding dimensional deviations, the specific context may include, but is not limited to, relevant standards for dimensional tolerances.
