Description

Technical Field

[0001] This utility model belongs to the field of liquid level indication technology, specifically relating to a wireless transmission system for liquid level over-limit alarm. Background Technology

[0002] The liquid level over-limit alarm wireless transmission system aims to achieve real-time monitoring of liquid levels and issue timely alerts when the liquid level exceeds the set threshold.

[0003] Current washing machine liquid level detection systems typically use a wired connection powered by batteries to connect the liquid level sensor to the measurement system, ensuring normal operation even in environments without power. While traditional wired connections offer relatively stable data transmission, they become cumbersome and limit system layout flexibility when expanding across multiple liquid level sensors. This is especially true in washing machines with complex internal structures or when sensors need to be placed at remote locations; wired connections require numerous power supply and signal transmission cables, leading to tedious installation and potential issues such as poor power connections or unstable signal transmission.

[0004] In order to enable wireless transmission of alarm signals when the liquid level exceeds the limit, a battery is usually added to the liquid level over-limit alarm transmission system. Although the battery can provide power for the liquid level over-limit alarm wireless transmission system, it is inconvenient to replace the battery when it is depleted due to frequent use, which is not conducive to the timely response of staff to the liquid level over-limit situation.

[0005] Therefore, in order to address the aforementioned technical issues, it is necessary to provide a wireless transmission system for liquid level over-limit alarms. Utility Model Content

[0006] The purpose of this invention is to provide a wireless transmission system for alarming excessive liquid levels, which can solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A wireless transmission system for alarming excessive liquid level includes a liquid level sensing float. The liquid level sensing float includes a first housing and a second housing, with a connecting structure installed between the first housing and the second housing. A replaceable structure is installed inside the first housing and the second housing. The replaceable structure includes multiple limiting rods, which are installed inside the liquid level sensing float. A battery is disposed between the limiting rods, and a limiting plate matching the battery is installed between the limiting rods.

[0009] In one or more embodiments of this utility model, the limiting rod is provided with a limiting groove that matches the limiting piece, and the limiting piece is provided with a limiting groove that matches the limiting rod.

[0010] In one or more embodiments of the present invention, a movable component is mounted on the replaceable structure, the movable component including a groove formed on a limiting piece.

[0011] In one or more embodiments of the present invention, the moving component includes a handle, which is mounted on a limiting plate.

[0012] In one or more embodiments of this utility model, the handle is provided with a plurality of anti-slip strips.

[0013] In one or more embodiments of the present invention, the connection structure includes a first connecting ring and a second connecting ring. The first connecting ring is fixedly connected inside the first housing and has a connecting groove. The second connecting ring is fixedly connected to the second housing. A plurality of connecting pieces are fixedly connected to one end of the second connecting ring near the first housing, and connecting blocks that match the connecting groove are installed on the connecting pieces.

[0014] In one or more embodiments of this utility model, a waterproof structure is installed between the liquid level sensing floats. The waterproof structure includes a plurality of sealing rubber rings, which are installed between the first housing and the second housing.

[0015] In one or more embodiments of this utility model, the waterproof structure and the liquid level sensing float are interference fit.

[0016] In one or more embodiments of this utility model, a wireless module is installed inside the liquid level sensing float, and the wireless module is selected as a CC2500S module.

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1-5 As shown, in one embodiment of this utility model, a wireless transmission system for over-limit liquid level alarm includes a liquid level sensing float. The float contains a battery, a wireless module, a liquid level detection device, and a water pump, all connected via an internal chip. When the float is placed inside a washing machine or dishwasher where the liquid level needs to be monitored, and the chip detects that the liquid level exceeds a preset value, it activates the wireless module to transmit a signal to the control system. The control system then issues an alarm based on the received signal and controls the opening and closing of the pump's inlet valve, thereby achieving automatic water level control.

[0031] The wireless transmission system can use the STM8L051F3 low-power control chip as the core control chip for the liquid level over-limit alarm wireless transmission system, and the CC2500S wireless transmission mode as the low-power wireless transmission mode. The device ID and the ID of the current liquid level sensor in the device group are set using a DIP switch. It can be powered by a 3V battery.

[0032] like Figures 1-5 As shown, the liquid level sensing float includes a first housing 1 and a second housing 2, with a connecting structure installed between the first housing 1 and the second housing 2. The connecting structure allows the first housing 1 and the second housing 2 to be separated for easy replacement of the battery 503.

[0033] like Figures 2-4 As shown, the connection structure includes a first connecting ring 301 and a second connecting ring 303. The first connecting ring 301 is fixedly connected inside the first housing 1, and a connecting groove 302 is formed inside the first connecting ring 301. The second connecting ring 303 is fixedly connected to the second housing 2, and a plurality of connecting pieces 304 are fixedly connected to one end of the second connecting ring 303 near the first housing 1. Connecting blocks 305 that match the connecting groove 302 are installed on the connecting pieces 304. According to the shape of the connecting groove 302, the second housing 2 is first pushed towards the first housing 1, then the second housing 2 is rotated along the shape of the connecting groove 302, and then the second housing 2 is pushed away from the first housing 1, so that the liquid level sensing float can be easily replaced with the battery 503.

[0034] like Figure 1 As shown, a waterproof structure is installed between the liquid level sensing floats. This waterproof structure is designed to prevent water from the equipment being monitored from flowing into the liquid level sensing floats, which could cause short circuits in the float's internal components and affect its normal operation. The waterproof structure includes several sealing rubber rings 401, which are installed between the first housing 1 and the second housing 2. The waterproof structure and the liquid level sensing floats are interference-fitted. The interference fit between the sealing rubber rings 401 and the liquid level sensing floats provides a better seal, further enhancing the waterproof effect.

[0035] like Figure 5 As shown, a replaceable structure is installed inside the first housing 1 and the second housing 2. This replaceable structure facilitates battery replacement by staff, mitigating the situation where frequent use leads to battery depletion, making battery replacement difficult and preventing staff from reacting promptly to excessive liquid levels. The replaceable structure includes multiple limiting rods 501, installed inside the liquid level sensing float. A battery 503 is positioned between the limiting rods 501, and a matching limiting plate 504 is installed between the limiting rods 501. Staff can quickly replace the battery 503 located between the limiting rods 501 and the limiting plate 504 by removing the limiting plate 504.

[0036] like Figure 5 As shown, the limiting rod 501 has a limiting groove 502 that matches the limiting piece 504, and the limiting piece 504 has a limiting groove 505 that matches the limiting rod 501. By rotating the limiting piece 504 until the limiting groove 505 aligns with the limiting rod 501, the restriction of the limiting piece 504 on the battery 503 can be released, allowing for quick replacement of the battery 503.

[0037] like Figure 5 As shown, the replaceable structure is equipped with a movable component, which includes a groove 506 formed on a limiting piece 504 and a handle 507 mounted on the limiting piece 504. When the operator has finished replacing the battery 503 and needs to install the limiting piece 504 onto the limiting rod 501, they press the groove 506 towards the limiting rod 501 according to its position, and then rotate the handle 507 until the limiting groove 505 is misaligned with the limiting rod 501, thus quickly replacing the battery 503.

[0038] like Figure 5 As shown, the handle 507 is provided with several anti-slip strips 508. The anti-slip strips 508 provide a certain amount of friction to prevent slippage when turning the handle 507, which would affect the battery 503 replacement efficiency.

[0039] like Figures 6-7 As shown, a wireless module, specifically a CC2500S module, is installed inside the liquid level sensing float. The core chip, an STM8L051F3, is also installed inside the liquid level sensing float.

[0040] During use, when the battery needs to be replaced, the second housing 2 is removed according to the shape of the connecting groove 302, and the limiting plate 504 is removed by rotating it according to the position of the limiting rod 501. The battery 503 is then replaced. After the replacement is completed, the limiting plate 504 and the second housing 2 are reinstalled, which can quickly complete the replacement of the battery 503. This avoids the installation trouble and wiring mess caused by wired connection as much as possible. At the same time, it avoids the situation where when the battery is depleted, the staff cannot detect the liquid level exceeding the limit in time because the battery 503 is inconvenient to replace, thus preventing the staff from reacting to the liquid level exceeding the preset value in time.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
