[0003] At present, there is a defoaming device on the water meter detection equipment (as described in patent number 201721661256.2) which uses a branch water pipe to extract the gas in the water meter to achieve the purpose of defoaming. The above structure is complicated and requires the use of multiple valves to control the water flow to achieve defoaming. Moreover, the defoaming work is discontinuous, so it is not suitable for ordinary water quality monitoring equipment.

[0004] The applicant has designed a liquid bubble elimination device for a water quality monitor to solve the above problems. Summary of the invention

However, the present disclosure can be embodied in different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure will be comprehensive and complete, and will fully convey the scope of the present disclosure to those skilled in the art. In addition, the present disclosure is limited only by the scope of the claims.

[0021] The shapes, sizes, ratios, angles and numbers disclosed in the drawings for describing the embodiments of the present disclosure are only examples, and therefore the present disclosure is not limited to the details shown. Throughout this specification, the same reference numerals refer to the same elements. In the following description, when the detailed description of the relevant known functions or configurations is determined to be unnecessary to blur the focus of the present disclosure, the detailed description will be omitted. In the case of using "including", "having" and "comprising" described in this specification, other parts may be added unless "only" is used. Unless otherwise indicated, the terms in the singular may include plural forms.

[0022] When explaining an element, although not explicitly described, the element is understood to include a range of error.

[0023] When describing a positional relationship, for example, when the positional relationship is described as "on," "above," "below," and "adjacent to," unless "immediately" or "directly" is used, one or more parts may be arranged between two other parts.

[0024] When describing a time relationship, for example, when a time sequence is described as “after,” “subsequently,” “next,” and “before,” discontinuous cases may be included unless “just” or “directly” is used.

[0025] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from other elements. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present disclosure.

[0026] As those skilled in the art can fully understand, the features of the different embodiments of the present disclosure can be coupled or combined with each other in part or in whole, and can cooperate with each other in various ways and be driven technically. The embodiments of the present disclosure can be performed independently of each other, or can be performed together in a mutually dependent relationship.

[0027] Reference Figure 1 The utility model discloses a liquid bubble elimination device, including a defoaming chamber 1. The defoaming chamber 1 of the present application is a square cavity. Of course, the defoaming chamber 1 can also be of other shapes. The defoaming chamber 1 includes an overflow chamber 2, a water inlet chamber 3 and a water outlet chamber 4 arranged from left to right. The water inlet chamber 3 is connected with the overflow chamber 2 through an overflow port 9, and the water inlet chamber 3 is connected with the water outlet chamber 4 through a water outlet 8. A water inlet hole 5 is provided on the cavity wall of the water inlet chamber 3, an overflow hole 6 is provided on the cavity wall of the overflow chamber 2, and a water outlet chamber 4 is provided on the cavity wall of the water outlet chamber 4. A water outlet hole 7 is provided, and external water enters the water inlet chamber 3 through the water inlet hole 5. Because the aperture of the water inlet hole 5 is larger than the aperture of the water outlet hole 7, the amount of water entering the water inlet chamber 3 through the water inlet hole 5 is larger than the amount of water flowing out through the water outlet hole 7. The bottom edge of the water outlet 8 is lower than the bottom edge of the overflow port 9, and the orifice area of ​​the overflow hole 6 is larger than the difference between the orifice area of ​​the water inlet hole 5 and the orifice area of ​​the water outlet hole 7. Therefore, the excess water entering the water inlet chamber 3 will flow out from the overflow hole 6 in time after passing through the overflow port 9 and the overflow chamber 2.

[0028] The principle of the above structure is that the fluctuation of the external water pressure of the water inlet hole 5 will cause the fluctuation of the water inlet volume, but when the overflow port 9 of the defoaming chamber 1 has a certain overflow volume, the fluctuation of the water inlet volume can only cause the fluctuation of the overflow volume, and will not affect the water flow rate of the water outlet 8 in the water outlet chamber 4. Therefore, the water flow rate of the water outlet 8 is stable, thereby ensuring that the water sample is at normal pressure and maintains a certain liquid level, stabilizing the water sample pressure and flow, eliminating bubbles, and ensuring stable measurement.

[0029] Moreover, the liquid enters the water inlet chamber 3 from the water inlet hole 5, and the bubbles in the liquid float upward to the liquid surface and enter the overflow chamber through the overflow port 9, and are discharged through the overflow hole 6. Because the bottom edge of the water outlet 8 is lower than the bottom edge of the overflow port 9, the bubble-free liquid flows downward through the water outlet 8, thereby effectively ensuring that the delivered liquid does not contain bubbles.

[0030] As a preferred structure, the overflow hole 6 is located on the bottom surface of the overflow chamber 2 ; the water inlet hole 5 is located on the bottom surface of the water inlet chamber 3 ; and the water outlet hole 7 is located on the bottom surface of the water outlet chamber 4 .

[0031] As shown in the figure, baffle plate 10 and baffle plate 2 11 are sequentially arranged in the defoaming chamber 1, the upper end of baffle plate 10 and the defoaming chamber 1 constitute an overflow port 9, the upper end of baffle plate 2 11 and the defoaming chamber 1 constitute an outlet port 8, the water inlet chamber 3 is between baffle plate 10 and baffle plate 2 11, the overflow chamber is formed by baffle plate 10 and part of the cavity wall of the defoaming chamber 1, the water outlet chamber is formed by baffle plate 2 11 and part of the cavity wall of the defoaming chamber 1, the height of baffle plate 10 is higher than the height of baffle plate 2 11, and three chambers of overflow chamber 2, water inlet chamber 3 and water outlet chamber 4 are formed by the above structure, and a structure is formed in which the bottom edge of the outlet port 8 is lower than the bottom edge of the overflow port 9.

[0032] As shown in the figure, it includes a circulation component body 12, which is a square box body and can be made of plastic. The defoaming chamber 1 is the inner cavity of the circulation component body 12, and the baffle 1 10 and the baffle 2 11 are arranged in parallel with the bottom surface of the circulation component body 12. The above structure is simple and easy to manufacture. The circulation component body 12 includes a main body 13 and a cover body 14, which can be machined or injection molded respectively, and the main body 13 and the cover body 14 can be fixed by screws. The main body 13 and the cover body 14 have regular shapes and simple structures, which reduces equipment costs.

[0033] The above is a detailed introduction to a liquid bubble elimination device provided by an embodiment of the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method of the utility model and its core idea; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
