Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to pressure tanks and water purification equipment. Background Technology

[0002] A water purifier is a device that removes impurities and contaminants from water using physical, chemical, or biological methods to provide clean and safe drinking water. Water purifiers typically have a pressure tank, which stores purified water in advance, increasing the water flow rate and saving users waiting time. If the pressure tank is not full, air in the water is released inside, increasing the risk of unpleasant odors in the water and affecting the stable water output of the purifier. If the pressure tank is overfilled, long-term use can easily damage the pressure bladder. Prior art, such as the earlier patent application number 202311486261.4, discloses a water purification system, water purification control method, and water purification equipment. This system uses a pressure tank to provide driving force for the water, replacing a water pump, allowing pure water to be transported in a designated direction in a circulation pipe. A pressure switch controls the delivery of treated pure water to the pressure tank for storage based on the detected pressure value. However, the pressure switch is prone to pressure drift over time, which can easily lead to insufficient or excessive water storage in the pressure tank, damaging the pressure bladder. Utility Model Content

[0003] The first objective of this invention is to provide a pressure tank that can solve the problem that the pressure switch of existing pressure tanks may drift after long-term use, which can easily cause the pressure tank to be not filled with water or to be damaged by excessive water.

[0004] The second objective of this invention is to provide a water purification device that can solve the problem of pressure value drift after long-term use of the pressure switch of the existing pressure tank, which can easily cause the pressure tank to be not full or to be damaged by excessive water storage. This ensures a stable water output from the water purification device and saves users' waiting time.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On one hand, a pressure tank is provided, including a tank body and a pressure bladder disposed in the tank body. The tank body has a water inlet and a water storage chamber connected to the water inlet. The pressure tank also includes a water level detection component and a pressure sensor. The water level detection component includes a water level connector and a water level sensor. The water level connector has a water-containing cavity, which is connected to the water storage chamber. The water level in the water-containing cavity is related to the water level in the water storage chamber. The water level sensor is used to detect the water level in the water-containing cavity, and the pressure sensor is used to detect the pressure inside the water storage chamber.

[0007] In one embodiment, the pressure tank further includes a connecting pipe connected to the tank body and the water level connector, with one end of the connecting pipe connected to the water storage chamber and the other end connected to the water holding chamber.

[0008] In one embodiment, the inlet end of the connecting pipe is located at the bottom of the water storage chamber, and the outlet end of the connecting pipe is located at the bottom of the water holding chamber.

[0009] In one embodiment, the pressure tank has a plurality of water level sensors, and the plurality of water level sensors detect different water level heights.

[0010] In one embodiment, a plurality of water level sensors are arranged sequentially at intervals along the height direction of the barrel, and among the plurality of water level sensors, the water level sensor located at the top is lower than the top of the water storage chamber.

[0011] In one embodiment, the water level connector is disposed on one side of the barrel and fixedly connected to the barrel.

[0012] In one embodiment, the water level connector includes a main body and an extension. The height of the main body extends along the height direction of the barrel and is connected to the side wall of the barrel. The water-containing cavity is disposed in the main body. The extension protrudes from the side of the main body and extends toward the axis of the barrel. The extension is connected to the top wall of the barrel.

[0013] In one embodiment, the water level sensor is a photoelectric sensor, the water level connector has a transparent sidewall, the photoelectric sensor is disposed on the outside of the transparent sidewall, and the detection light of the photoelectric sensor can pass through the transparent sidewall.

[0014] In one embodiment, the pressure tank further includes inlet and outlet water pipes, one end of which is connected to a water supply end and the other end is connected to the tank body. The inlet and outlet water pipes are connected to the water inlet, and the pressure sensor is disposed on the inlet and outlet water pipes.

[0015] On the other hand, a water purification device is provided, including a pressure tank as described in any of the above embodiments. The water purification device also includes a water supply path, the pressure tank is disposed in the water supply path, and the water supply path is connected to the water user.

[0016] The beneficial effects of this utility model are:

[0017] The pressure tank provided by this utility model includes a tank body and a pressure bladder disposed within the tank body. The tank body has a water inlet and a water storage chamber connected to the water inlet. Purified water from the water purification module enters the water storage chamber through the water inlet for pre-storage. The pressure tank also includes a water level detection component and a pressure sensor. The water level detection component includes a water level connector and a water level sensor. The water level connector has a water-containing cavity that connects to the water storage chamber, and the water level in the water-containing cavity is related to the water level in the water storage chamber. The water level sensor is used to detect the water level in the water-containing cavity. Since the water level in the water-containing cavity is related to the water level in the water storage chamber, the detection value of the water level sensor can also express the water level in the water storage chamber, achieving the purpose of detecting the water level in the water storage chamber. By detecting the water level in the water storage chamber, it is determined whether the pressure tank needs to store water and whether the amount of water stored is appropriate. Simultaneously, a pressure sensor detects the pressure inside the water storage chamber, which is related to the water level. When the water level decreases, the pressure decreases accordingly; conversely, when the water level increases, the pressure rises. When both the water level and pressure sensor readings are consistent, it indicates that the pressure tank needs to store water or stop storing water. For example, if both sensors indicate insufficient water, water needs to be added promptly. This dual detection of pressure and water levels allows for precise control of the water level within the pressure tank, controlling both storage and supply. This avoids the pressure drift risk associated with pressure switches, prevents unpleasant odors caused by gas release from the water due to insufficient water, and mitigates damage to the pressure bladder from prolonged over-storage.

[0018] The water purification device provided by this utility model has the aforementioned pressure tank. The pressure tank controls the water storage and supply by using both pressure sensor to detect the internal pressure and water level sensor to detect the water level. This allows for more precise control of the water level in the pressure tank, avoiding the risk of pressure drift caused by pressure switches. It also prevents problems such as odor caused by gas being released from the water due to insufficient water storage, or damage to the pressure bladder due to excessive water storage over a long period. This improves the water flow rate and stability of the water purification device, saves user waiting time, and enhances the user experience. Attached Figure Description

Detailed Implementation

[0024] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0025] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0026] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0027] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0028] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0029] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0030] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0031] like Figure 1 As shown, this utility model first provides a pressure tank, which includes a tank body 1 and a pressure air bladder (not shown in the figure) disposed inside the tank body 1. The tank body 1 has a water inlet 11 and a water storage chamber connected to the water inlet 11. The purified water from the water purification module enters the water storage chamber through the water inlet 11 for pre-storage.

[0032] The pressure tank also includes a water level detection component 2 and a pressure sensor 3. The water level detection component 2 includes a water level connector 21 and a water level sensor 22. The water level connector 21 has a water-containing cavity 211, which connects to the water storage cavity. The water level in the water-containing cavity 211 is related to the water level in the water storage cavity. The water level sensor 22 is used to detect the water level in the water-containing cavity 211. Since the water level in the water-containing cavity 211 is related to the water level in the water storage cavity, the detected value of the water level sensor 22 can also express the water level in the water storage cavity, thus achieving the purpose of detecting the water level in the water storage cavity. By detecting the water level in the water storage cavity, it is determined whether the pressure tank needs to store water and whether the amount of water stored is appropriate. At the same time, the pressure sensor 3 is used to detect the pressure inside the water storage cavity. The pressure inside the water storage cavity is related to the water level in the water storage cavity; when the water level in the water storage cavity decreases, the pressure inside the cavity also decreases accordingly; when the water level in the water storage cavity increases, the pressure inside the cavity also increases accordingly. When the detection results of the water level sensor 22 and the pressure sensor 3 are consistent, it indicates that the pressure tank needs to store water or stop storing water. For example, if both the water level sensor 22 and the pressure sensor 3 show that the water level in the storage chamber is insufficient, water needs to be added in time. By using the dual detection of the internal pressure detected by the pressure sensor 3 and the water level detected by the water level sensor 22, the water level in the pressure tank can be controlled more accurately, thus controlling the water storage and supply of the tank 1. This avoids the risk of pressure value drift caused by using a pressure switch, prevents the release of gas in the water due to insufficient water storage in the tank 1, which could cause odor problems in the water, or damage to the pressure bladder due to excessive water storage in the tank 1 over a long period of time.

[0033] The pressure tank also includes a connecting pipe 4 that connects the tank body 1 and the water level connector 21. One end of the connecting pipe 4 is connected to the water storage chamber, and the other end is connected to the water holding chamber 211. Through the connecting pipe 4, the water storage chamber and the water holding chamber 211 are connected, so that the water level in the water holding chamber 211 is related to the water level in the water storage chamber.

[0034] Specifically, the inlet of the connecting pipe 4 is located at the bottom of the water storage chamber, and the outlet of the connecting pipe 4 is located at the bottom of the water holding chamber 211. When purified water enters the water storage chamber through the inlet 11, the water level in the water storage chamber rises, and at the same time, some purified water flows into the water holding chamber 211 through the connecting pipe 4, causing the water level in the water holding chamber 211 to rise synchronously and be related to the water level in the water storage chamber.

[0035] In one embodiment, the pressure bladder is located at the lower part of the barrel 1, and a water storage chamber is formed above the pressure bladder. Therefore, the bottom of the water storage chamber is located at the middle of the height direction of the barrel 1. Figure 1As shown. The bottom of the water level connector 21 is slightly higher than the bottom of the water storage chamber, and the water receiving chamber 211 is a long and narrow cavity to save water. A small amount of clean water flows into the water receiving chamber 211 to ensure that the water level in the water receiving chamber 211 is related to the water level in the water storage chamber.

[0036] In one embodiment, the pressure tank is equipped with multiple water level sensors 22, each corresponding to a different water level. The multiple water level sensors 22 are arranged sequentially at intervals along the height of the tank body 1. For example, in one embodiment, the pressure tank is equipped with three water level sensors 22: a high water level sensor 221, a medium water level sensor 222, and a low water level sensor 223. The high water level sensor 221 detects a first preset water level, the low water level sensor 223 detects a third preset water level, and the medium water level sensor 222 detects a second preset water level. The first preset water level is higher than the second preset water level, and the second preset water level is higher than the third preset water level. By detecting these three different water levels, different operations can be performed on the pressure tank to meet the user's water usage needs.

[0037] Among the multiple water level sensors 22, the top water level sensor 22 is lower than the top of the water storage chamber. Along the height of the tank 1, the low water level sensor 223, the medium water level sensor 222, and the high water level sensor 221 are arranged sequentially from bottom to top. The top water level sensor 22 is also the high water level sensor 221. The high water level sensor 221 is lower than the top of the water storage chamber, ensuring timely water storage in the pressure tank and preventing damage caused by excessive emptying of the pressure tank.

[0038] Specifically, the process of controlling the water storage and supply of tank 1 through dual detection of the internal pressure detected by pressure sensor 3 and the water level height detected by water level sensor 22 is as follows: The parameters of the pressure tank include a first preset pressure, a second preset pressure, and a third preset pressure. Among them, the first preset pressure is greater than the second preset pressure, the second preset pressure is greater than the third preset pressure, and the first preset pressure corresponds to the first preset water level; the second preset pressure corresponds to the second preset water level, and the third preset pressure corresponds to the third preset water level. When the low water level sensor 223 is triggered and the pressure sensor 3 detects that the pressure inside the chamber is lower than the third preset pressure, it indicates that the water level in the storage chamber is lower than the third preset water level and the pressure tank is not storing enough water, so water needs to be stored. When the high water level sensor 221 is triggered and the pressure sensor 3 detects that the pressure inside the chamber is higher than the first preset pressure, it indicates that the water level in the storage chamber is higher than the first preset water level, and the pressure tank has completed water storage. When the medium water level sensor 222 is triggered and the pressure sensor 3 detects that the pressure inside the chamber is lower than the second preset pressure, it indicates that the water level in the pressure tank is the second preset water level, and the water level is not enough to provide a large flow rate. The water purification equipment can supplement the flow rate through other equipment to meet the user's water demand.

[0039] The water level connector 21 is located on one side of the tank body 1 and is fixedly connected to the tank body 1. The water level connector 21 and the tank body 1 can be connected by welding to keep the position of the water level connector 21 stable and avoid affecting the detection accuracy of the water level detection component 2.

[0040] like Figure 2 As shown, the water level connector 21 includes a main body 212 and an extension 213. The height of the main body 212 extends along the height direction of the barrel 1 and is connected to the side wall of the barrel 1. A water-containing cavity 211 is disposed in the main body 212 and is in the shape of a long and narrow cavity. The extension 213 protrudes from the side of the main body 212 and extends toward the axis of the barrel 1. The extension 213 is connected to the top wall of the barrel 1, increasing the connection area between the water level connector 21 and the barrel 1, and further improving the positional stability of the water level connector 21.

[0041] In one embodiment, the water level sensor 22 is a photoelectric sensor, and the water level connector 21 has a transparent sidewall 214. The photoelectric sensor is disposed on the outside of the transparent sidewall 214, and the detection light of the photoelectric sensor can pass through the transparent sidewall 214. The photoelectric sensor has high detection accuracy, and the external detection method will not affect the water quality. The specific structure and detection principle of the photoelectric sensor can be set with reference to the prior art, and will not be described in detail in this embodiment.

[0042] The pressure tank also includes inlet and outlet water pipes 5. One end of the inlet and outlet water pipes 5 is connected to the water supply end, and the other end is connected to the tank body 1. The inlet and outlet water pipes 5 are connected to the water inlet 11, and the pressure sensor 3 is installed on the inlet and outlet water pipes 5. Pipe fittings are provided on the inlet and outlet water pipes 5, and the pressure sensor 3 is installed on the inlet and outlet water pipes 5 by fastening screws 6, such as... Figure 3 As shown.

[0043] This embodiment also provides a water purification device, which includes a pressure tank as described in any of the above embodiments. The device also includes a water supply path, with the pressure tank disposed within the water supply path, which is connected to the water-using end. The water level detection component 2 of the pressure tank includes a water level connector 21 and a water level sensor 22. The water level connector 21 has a water-containing cavity 211, which is connected to a water storage cavity. The water level in the water-containing cavity 211 is related to the water level in the water storage cavity. The water level sensor 22 is used to detect the water level in the water-containing cavity 211. Since the water level in the water-containing cavity 211 is related to the water level in the water storage cavity, the detection value of the water level sensor 22 can also express the water level in the water storage cavity, thus achieving the purpose of detecting the water level in the water storage cavity. Meanwhile, pressure sensor 3 is used to detect the pressure inside the water storage chamber, which is related to the water level. When the water level decreases, the pressure decreases accordingly; when the water level increases, the pressure increases accordingly. Through the dual detection of the pressure sensor 3 and the water level sensor 22, the water storage and supply in tank 1 are controlled. This allows for more precise control of the water level in the pressure tank, avoiding the risk of pressure drift associated with pressure switches. It also prevents odor problems caused by gas release from the water due to insufficient water storage in tank 1, or damage to the pressure bladder due to excessive water storage over a long period. This improves the water flow rate and stability of the water purifier, saves user waiting time, and enhances the user experience.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
