Description

Technical Field

[0001] The invention relates to a portable ultrasonic transducer sealing structure, belonging to the technical field of ultrasonic imaging equipment. Background Art

[0002] At present, the application of ultrasound equipment in clinical diagnosis and treatment has become very popular, and has made great contributions to doctors' accurate understanding of patients' conditions, formulation of medical plans, and auxiliary treatment. In order to adapt to various different usage environments, miniaturized ultrasound products continue to appear and become more and more popular. The sealing performance of the ultrasound host shell is the guarantee of the performance of the ultrasonic transducer. At present, the waterproof structure of the ultrasound host shell is the most difficult design problem in the industry. The previous practice is to add some sealing O-rings or use glue to seal. These existing methods have their shortcomings and limitations: O-rings are difficult to assemble for precise and small structures, because O-rings are soft materials and it is difficult to put them in the corresponding position according to people's wishes; although the glue filling solution can be waterproof, subsequent maintenance is very difficult, and heat dissipation is also a problem. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a portable ultrasonic transducer sealing structure that is easy to install and maintain and can achieve effective sealing of the host housing.

[0004] According to the technical solution provided by the present invention, the portable ultrasonic transducer sealing structure includes a waterproof layer arranged between the matching surfaces of multiple components of the ultrasonic host housing, and the waterproof layer is integrated with one or more components of the ultrasonic host housing.

[0005] Furthermore, the waterproof layer and the components of the ultrasonic host housing are integrally formed by a mold to form a composite structure.

[0006] Furthermore, the waterproof layer is pressed or bonded to the components of the ultrasonic host housing into one body.

[0007] Furthermore, one side of the waterproof layer is a connection surface with a component of the ultrasonic host housing, and the other side of the waterproof layer is a sealing surface, which is sealed with other components of the ultrasonic host housing.

[0008] Furthermore, the waterproof layer is made of TPE, TPU or waterproof silicone material.

[0009] Furthermore, the waterproof layer completely covers the mating surfaces between the multiple components of the ultrasonic host housing.

[0010] Furthermore, the ultrasound host housing includes a host upper housing, a host lower housing and a probe housing.

[0011] Furthermore, the waterproof layer is arranged on the matching surface between the main unit lower shell and the main unit upper shell and the probe shell.

[0012] Furthermore, the waterproof layer is arranged on the upper shell of the main unit and at the matching surface between the lower shell of the main unit and the outer shell of the probe.

[0013] Furthermore, a waterproof layer is provided at the mating surfaces of the mainframe upper shell, the mainframe lower shell and the probe shell, and at the mating surfaces of the mainframe lower shell, the mainframe upper shell and the probe shell.

[0014] The ultrasonic transducer sealing structure of the present invention realizes effective waterproof sealing of the ultrasonic host housing by forming a composite structure integrated with the ultrasonic host housing, and the sealing structure can avoid the problem of difficult installation of the ultrasonic host housing, and is easy to install and maintain.

[0025] The present invention will be further described below in conjunction with the specific drawings.

[0026] The portable ultrasonic transducer sealing structure of the present invention is used to achieve waterproof sealing between the mating surfaces of two or more components. The ultrasonic host housing is generally composed of multiple components, and in this embodiment includes a host upper shell 110, a host lower shell 120 and a probe shell 130; Figure 1 As shown, the sealing structure of the present invention is used to achieve waterproof sealing between the mating surfaces of multiple components of the ultrasound host housing. The sealing structure includes a waterproof layer 200. The waterproof layer 200 is arranged on the mating surface of the host lower shell 120 with the host upper shell 110 and the probe housing 130. The waterproof layer 200 and the host lower shell 120 are integrally formed by a mold to form a composite structure, which is convenient for installation and maintenance, avoids installation difficulties and achieves a good waterproof sealing effect; the waterproof layer 200 can completely cover the mating surfaces of the host lower shell 120 and the host upper shell 110 and the probe housing 130, as shown in FIG. Figure 2a , Figure 2b , Figure 3a , Figure 4a As shown, after the main body upper shell 110, the main body lower shell 120 and the probe housing 130 are assembled, the waterproof layer 200 is located between the mating surfaces of the main body upper shell 110, the main body lower shell 120 and the probe housing 130 to achieve waterproof sealing of the gap between the main body upper shell 110, the main body lower shell 120 and the probe housing 130.

[0027] As a specific embodiment of the present invention, the waterproof layer 200 is arranged on the mainframe upper shell 110 at the mating surface between the mainframe lower shell 120 and the probe housing 130, and the waterproof layer 200 and the mainframe upper shell 110 are integrally formed by a mold to form a composite structure.

[0028] As another specific embodiment of the present invention, the waterproof layer 200 can be arranged on the mating surfaces of the host upper shell 110, the host lower shell 120 and the probe housing 130 by pressing or bonding; specifically, the waterproof layer 200 can be pressed or bonded to the host upper shell 110 and / or the host lower shell 120 at high temperature.

[0029] like Figure 2b As shown, one side of the waterproof layer 200 is a connection surface 210 connected to the mainframe upper shell 110 or the mainframe lower shell 120, and the other side of the waterproof layer 230 is a sealing surface 220 matched with another component (specifically, the mainframe lower shell 120, the mainframe upper shell 110 or the probe body 130); the connection surface 210 and a component of the ultrasound mainframe housing (specifically: the mainframe upper shell 110 or the mainframe lower shell 120) are integrally formed, pressed or bonded together by a mold; the sealing surface 220 is sealed and matched with another component of the ultrasound mainframe housing.

[0030] The waterproof layer 200 may be made of materials such as TPE (polyolefin elastomer), TPU (polyurethane elastomer), and waterproof silicone.

[0031] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
