Description

Technical Field

[0001] This utility model relates to the field of ultrasonic watch housing technology, and in particular to an ultrasonic watch housing with good water flow stability. Background Technology

[0002] Ultrasonic water meters typically feature a straight pipe casing to facilitate direct water flow and accurate flow measurement. However, due to the plastic material used in injection molding, this straight pipe structure is prone to deformation, affecting water flow. Deformed areas can also cause blockages within the straight pipe, further impacting flow measurement. Furthermore, current ultrasonic meter casings often contain various internal components that obstruct water flow, resulting in poor flow stability and potentially inaccurate measurements.

[0003] Therefore, how to design and implement an ultrasonic casing with good water flow stability has become a technical problem that needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide an ultrasonic housing with good water flow stability.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An ultrasonic watch case with good water flow stability is provided. The ultrasonic watch case includes a straight tube-shaped watch case body; a water flow pipeline is provided inside the watch case body; four symmetrically distributed partition chambers are provided in the middle of the watch case body; the partition chambers are located outside the water flow pipeline; each partition chamber is connected to the other two through two connecting ports; and water-proof ribs are provided between the partition chambers and the side wall of the watch case body for water isolation.

[0007] Furthermore, a temperature sensor is provided at the middle position of the outer side of the main body of the watch case; the temperature sensor is located below the partition chamber; a lower exhaust port connected to the water flow pipe is provided at the bottom of the temperature sensor; two side exhaust ports are provided on the side of the temperature sensor located in the partition chamber; the lower exhaust port and the side exhaust ports are connected to each other.

[0008] Furthermore, two transducers are symmetrically arranged on the main body of the watch case; the two transducers are located on both sides of the temperature sensor; the transducers extend into the interior of the main body of the watch case and are attached to the water flow pipe below.

[0009] Furthermore, both ends of the main body of the watch case are provided with threaded connection ports for connecting external pipelines.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This invention, through the arrangement of four interconnected partition chambers and the design of the water flow pipeline, places components such as temperature sensors within the partition chambers instead of directly inserting them into the water flow pipeline. This allows the water flow to pass through with virtually no obstruction, improving the stability of the water flow and thus enhancing measurement accuracy. At the same time, the venting port facilitates the expulsion of air, and the temperature sensor can quickly collect water temperature data while venting, maintaining stable measurement.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Example

[0023] like Figures 1-3 As shown, an ultrasonic meter housing with good water flow stability includes a straight-tube housing body 1. A water flow pipe 2 is installed inside the housing body 1. The water flow direction of the water flow pipe 2 is shown by the arrows in the figure. In terms of water flow capacity, the inclined side has the strongest water flow capacity, slightly greater than the two ends, and the two ends have a slightly greater water flow capacity than the middle end. The entire process has minimal impact on the water flow, and there are no places where foreign objects can get stuck, so it will not affect the measurement. The housing body 1 has four symmetrically distributed... The spacer chamber 3 is located outside the water flow pipe 2. The design of the spacer chamber 3 allows for gaps during injection molding, preventing structural deformation. At the same time, the spacer chamber 3 ensures that there are no other components obstructing the water flow pipe 2, stabilizing the water flow and improving metering accuracy. Each of the spacer chambers 3 is connected by two connecting ports 4 to facilitate venting and avoid the formation of multiple sealed cavities. A water-proof rib 5 is provided between the spacer chamber 3 and the side wall of the main body 1 for water-proof sealing, preventing water from flowing into the chamber.

[0024] A temperature sensor 6 is located at the center of the outer side of the main body 1 of the watch case. The temperature sensor 6 is positioned below the partition chamber 3. A lower vent 7 connected to the water flow pipe 2 is located at the bottom of the temperature sensor 6. Two side vents 8 are located on the side of the temperature sensor 6 within the partition chamber 3. The lower vent 7 and the side vents 8 are connected to facilitate the expulsion of air. While venting air, the temperature sensor 6 can quickly collect the water temperature to maintain stable measurement. Two transducers 9 are symmetrically arranged on the main body 1 of the watch case. The two transducers 9 are located on both sides of the temperature sensor 6. The transducers 9 extend into the interior of the main body 1 of the watch case and fit against the water flow pipe 2. Threaded connection ports 10 are provided at both ends of the main body 1 of the watch case for connecting to external pipes.

[0025] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
