Description

Technical Field

[0001] The utility model relates to the field of water purifiers, in particular to a sound insulation component. Background Art

[0002] In the prior art, when the water purifier is in the hot water outlet condition, the DC pump will start to work, but the DC pump will generate very obvious noise when working, which affects the user experience. Therefore, this problem needs to be solved urgently. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a sound insulation component in order to overcome the defect of a water purifier in the prior art that the water purifier makes a lot of noise under hot water working conditions.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A sound insulation component is arranged on a DC pump to soundproof the DC pump, and the sound insulation component includes a sound insulation pad sleeved at the end of the DC pump and a sound insulation cover arranged on the outer wall surface of the sound insulation pad, wherein the sound insulation cover and the end side wall surface of the sound insulation pad are in contact with each other along the flow direction of the fluid, and / or the sound insulation cover and the circumferential side wall surface of the sound insulation pad are in contact with each other along the radial direction perpendicular to the flow of the fluid.

[0006] In the present technical solution, when the DC pump is working, a sound insulation pad is set at the end of the DC pump to limit the DC pump and prevent it from vibrating itself, and a sound insulation cover is set on the outer wall surface of the DC pump and the outer wall surface of the sound insulation pad to block the propagation of noise generated by the DC pump, thereby significantly reducing the noise level generated by the DC pump when it is working, and improving the comfort and satisfaction of users when using the water purifier.

[0007] Preferably, the sound insulation pad comprises a first sound insulation pad and a second sound insulation pad arranged at two ends of the DC pump along the flow direction of the fluid.

[0008] The first sound insulation pad is provided with an avoidance hole for avoiding the terminal post;

[0009] The second sound insulation pad is provided with a through hole for the water supply pipe to pass through.

[0010] In the present technical solution, by providing an avoidance hole on the first sound insulation pad, it can be ensured that the extension of components such as the terminal or the throttling column does not affect their normal work; by providing a through hole for the water supply pipe on the second sound insulation pad, on the one hand, the normal working state of the water pipe can be guaranteed, and on the other hand, the vibration of the water pipe itself can be reduced when fluid passes through the water pipe, so that it will not generate additional vibration and noise, thereby further improving the sound insulation effect of the sound insulation assembly.

[0011] Preferably, the first sound insulation pad is an annular columnar structure, and two extension parts extending toward the central axis direction of the first sound insulation pad are provided at the liquid inlet end of the first sound insulation pad along the fluid flow direction, and the avoidance hole is formed between the side wall surfaces of the two extension parts and the inner wall surface of the first sound insulation pad, and the cross-sectional dimension between the two relatively arranged extension parts is adapted to the cross-sectional dimension of the terminal.

[0012] In the technical solution, two extensions are provided at the liquid inlet end of the first sound insulation pad along the fluid flow direction, and the two extensions and the inner wall surface of the sound insulation pad form a avoidance hole, which can ensure the extension of components such as the terminal or the throttle column. At the same time, the cross-sectional dimensions of the two relatively arranged extensions are adapted to the cross-sectional dimensions of the terminal, which not only ensures that the sound insulation component will not interfere with the normal operation of the terminal, but also ensures that the terminal can pass through the avoidance hole steadily without generating additional friction or vibration, further improving the sound insulation effect to ensure the stability of the sound insulation component.

[0013] Preferably, the liquid inlet end of the second sound insulation pad along the fluid flow direction is an annular columnar structure, and two through holes are formed at the liquid outlet end of the second sound insulation pad along the fluid flow direction. The cross-sectional size of the through holes is adapted to the cross-sectional size of the water pipe.

[0014] In the present technical solution, a through hole is provided on the second sound insulation pad, which can ensure that the water pipe can pass through the sound insulation pad smoothly without generating additional friction or vibration, so as to further improve the stability of the water pipe and reduce the conduction of noise.

[0015] Preferably, a groove is provided on the inner wall surface of the annular columnar structure, and the groove and the inner wall surface of one of the through holes are smoothly connected to form the through hole.

[0016] In the present technical solution, this structural form can be adapted to water pipes of different structural sizes to ensure that the water pipes pass through the sound insulation component smoothly. In addition, the setting of the groove can increase the stability of the water pipe passing through the through hole, preventing the water pipe from loosening or vibrating in the through hole. The smooth connection design forms a tight connection between the through hole and the water pipe, and can also effectively prevent the water pipe from swinging to further reduce noise generation. At the same time, since the setting of the groove increases the size of the outer wall of the water pipe covered by the second sound insulation pad, the larger surface area and contact surface can effectively reduce the noise propagation generated when the water pipe is working.

[0017] Preferably, along the radial direction of fluid flow, the cross-sectional dimension of the second sound insulation pad is larger than the cross-sectional dimension of the first sound insulation pad;

[0018] And / or, along the flow direction of the fluid, the extension dimension of the second sound insulation pad is greater than the extension dimension of the first sound insulation pad.

[0019] In the present technical solution, since the size of the second sound insulation pad is larger than that of the first sound insulation pad, its surface area is also increased accordingly, which can provide more surfaces for absorbing vibrations and sound waves, so as to improve the sound insulation effect from the end where the DC pump has the loudest noise, thereby reducing the noise level generated when the DC pump is running.

[0020] Preferably, the sound insulation cover comprises a first sound insulation cover and a second sound insulation cover which are arranged on the sound insulation pad along the flow direction of the fluid, and the first sound insulation cover and the second sound insulation cover are seamlessly connected at a connection point.

[0021] In the present technical solution, since the first sound insulation cover and the second sound insulation cover are seamlessly connected at the connection, no noise or trace noise can flow out from the connection. This tightly connected design effectively blocks the noise transmission generated by the DC pump and prevents it from spreading to the surrounding environment, thereby improving the sound insulation effect.

[0022] Preferably, along the flow direction of the fluid, the second sound insulation cover at least partially covers the first sound insulation cover.

[0023] In this technical solution, the second sound insulation cover partially covers the first sound insulation cover, which can increase the thickness and density of the sound insulation layer and effectively reduce the propagation of noise. This superimposed design can provide thicker sound insulation material to absorb and block noise, thereby further reducing the noise level generated when the DC pump is running.

[0024] Preferably, along the radial direction of fluid circulation, the cross-sectional dimension of the second sound insulation cover is larger than the cross-sectional dimension of the first sound insulation cover.

[0025] In the present technical solution, since the size of the second sound insulation cover is larger than that of the first sound insulation cover, its surface area is also increased accordingly. It can not only adapt to the cross-sectional size of the water outlet pipe at the DC pump end, but also provide more surfaces for absorbing vibrations and sound waves, so as to improve the sound insulation effect from the end where the DC pump has the loudest noise, thereby reducing the noise level generated when the DC pump is running.

[0026] Preferably, a wire outlet hole is provided at the end of the first soundproof cover and at the central axis of the first soundproof cover;

[0027] The second sound insulation cover is provided with a connection hole through which the water supply pipe extends.

[0028] In the present technical solution, a wire outlet hole is provided at the end of the first sound insulation cover, and a connection hole for extending the water supply pipe is provided on the second sound insulation cover. Such a design not only ensures the normal operation of the various components, but also makes the line layout more simple and neat, making the structure of the various components compact and non-interfering with each other.

[0029] The positive progressive effect of the utility model is that the sound insulation component, when the DC pump is working, sets a sound insulation pad at the end of the DC pump to limit the DC pump to prevent itself from vibrating, and then sets a sound insulation cover on the outer wall surface of the DC pump and the outer wall surface of the sound insulation pad to block the propagation of noise generated by the DC pump, thereby significantly reducing the noise level generated by the DC pump when it is working, and improving the comfort and satisfaction of users when using the water purifier.

[0056] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0057] like Figure 1-Figure 3 As shown, a sound insulation component 200 is disclosed, which is arranged on the DC pump 100 of the water purifier to soundproof the DC pump 100.

[0058] The sound insulation component 200 includes a sound insulation cover 22 and a sound insulation pad 21 . Specifically, the sound insulation pad 21 is sleeved at the end of the DC pump 100 , and the sound insulation cover 22 is covered on the outer wall surface of the sound insulation pad 21 and the outside of the DC pump 100 .

[0059] The end side walls of the soundproof cover 22 and the soundproof pad 21 are in contact with each other along the flow direction X of the fluid, and the circumferential side walls of the soundproof cover 22 and the soundproof pad 21 are in contact with each other along the radial direction perpendicular to the flow of the fluid.

[0060] The principle of achieving the sound insulation effect by using the sound insulation component 200 of the above-mentioned structural form in the present embodiment is as follows: when the DC pump is working, a sound insulation pad 21 is provided at the end of the DC pump 100 to limit the DC pump to prevent itself from vibrating, and a sound insulation cover 22 is provided on the outer wall surface of the DC pump and the outer wall surface of the sound insulation pad 21 to block the propagation of noise generated by the DC pump 100, thereby significantly reducing the noise level generated when the DC pump is working and improving the comfort and satisfaction of users when using the water purifier.

[0061] like Figure 2-Figure 7As shown, the sound insulation pad 21 includes a first sound insulation pad 211 and a second sound insulation pad 212 arranged at both ends of the DC pump 100 along the flow direction X of the fluid. In addition, a avoidance hole 2111 for avoiding the terminal post is provided on the first sound insulation pad 211, and a through hole 2121 for the water supply pipe 11 to pass through is provided on the second sound insulation pad 212. By providing the avoidance hole 2111 on the first sound insulation pad 211, it can be ensured that the extension of components such as the terminal post or the throttling post does not affect their normal operation; by providing the through hole 2121 for the water supply pipe 11 to pass through on the second sound insulation pad 212, on the one hand, the normal working state of the water pipe 11 can be ensured, and on the other hand, the vibration of the water pipe 11 itself can be reduced when the fluid passes through the water pipe 11, so that it does not generate additional vibration and noise, further improving the sound insulation effect of the sound insulation component 200.

[0062] like Figure 4-Figure 5 As shown, the first sound insulation pad 211 is an annular columnar structure, and two extension parts 2112 extending toward the central axis direction of the first sound insulation pad 211 are provided at the liquid inlet end of the first sound insulation pad 211 along the fluid flow direction, and avoidance holes 2111 are formed between the side walls of the two extension parts 2112 and the inner wall surface of the first sound insulation pad 211, and the cross-sectional dimensions between the two extension parts 2112 relatively arranged are adapted to the cross-sectional dimensions of the terminal.

[0063] In this embodiment, the avoidance hole 2111 formed by the above-mentioned structural form can ensure the extension of components such as the terminal post or the throttle post. At the same time, the cross-sectional dimensions of the two relatively arranged extension portions 2112 are adapted to the cross-sectional dimensions of the terminal post, which not only ensures that the sound insulation component 200 will not interfere with the normal operation of the terminal post, but also ensures that the terminal post can pass through the avoidance hole 2111 steadily without generating additional friction or vibration, further improving the sound insulation effect and ensuring the stability of the sound insulation component 200.

[0064] like Figure 6-Figure 7 As shown, the liquid inlet end of the second sound insulation pad 212 along the fluid flow direction is an annular columnar structure, and two through holes 2121 are formed at the liquid outlet end of the second sound insulation pad 212 along the fluid flow direction. The cross-sectional size of the through hole 2121 is compatible with the cross-sectional size of the water pipe 11.

[0065] In this embodiment, a through hole 2121 is provided on the second sound insulation pad 212 to ensure that the water pipe 11 can smoothly pass through the sound insulation pad 21 without generating additional friction or vibration, so as to further improve the stability of the water pipe 11 and reduce the conduction of noise.

[0066] Preferably, a groove 2122 is provided on the inner wall surface of the annular columnar structure, and the groove 2122 and the inner wall surface of one of the through holes 2121 are smoothly connected to form the through hole 2121. With this structural form, water pipes 11 of different structural sizes can be adapted to ensure that the water pipe 11 passes through the sound insulation component 200 smoothly. In addition, the provision of the groove 2122 can increase the stability of the water pipe 11 passing through the through hole 2121, prevent the water pipe 11 from loosening or vibrating in the through hole 2121, and the smooth connection design forms a tight connection between the through hole 2121 and the water pipe 11, and can also effectively prevent the water pipe 11 from swinging to further reduce the noise generation. At the same time, since the provision of the groove 2122 increases the size of the outer wall surface of the water pipe 11 covered by the second sound insulation pad 212, the larger surface area and contact surface can effectively reduce the noise propagation generated when the water pipe 11 is working.

[0067] In addition, along the radial direction of fluid circulation, the cross-sectional dimension of the second sound insulation pad 212 is greater than the cross-sectional dimension of the first sound insulation pad 211 , and at the same time, along the fluid circulation direction X, the extension dimension of the second sound insulation pad 212 is greater than the extension dimension of the first sound insulation pad 211 .

[0068] In this embodiment, since the size of the second sound insulation pad 212 is larger than that of the first sound insulation pad 211, its surface area is also increased accordingly, which can provide more surfaces for absorbing vibrations and sound waves, so as to improve the sound insulation effect from the end where the DC pump 100 has the loudest noise, thereby reducing the noise level generated when the DC pump is running.

[0069] like Figure 8-Figure 9 As shown, the soundproof cover 22 specifically includes a first soundproof cover 221 and a second soundproof cover 222 which are arranged on the soundproof pad 21 along the flow direction X of the fluid, and the first soundproof cover 221 and the second soundproof cover 222 are seamlessly connected at the connection. Since the first soundproof cover 221 and the second soundproof cover 222 are seamlessly connected at the connection, no noise or a trace amount of noise can flow out from the connection. This tightly connected design effectively blocks the noise transmission generated by the DC pump and prevents it from spreading to the surrounding environment, thereby improving the sound insulation effect.

[0070] like Figure 2 As shown, along the flow direction X of the fluid, the second sound insulation cover 222 at least partially covers the first sound insulation cover 221 , that is, the second sound insulation cover 222 partially overlaps with the first sound insulation cover 221 when extending toward the first sound insulation cover 221 .

[0071] In this embodiment, the second sound insulation cover 222 partially covers the first sound insulation cover 221, which can increase the thickness and density of the sound insulation layer and effectively reduce the propagation of noise. This superimposed design can provide thicker sound insulation material to absorb and block noise, thereby further reducing the noise level generated when the DC pump is running.

[0072] Preferably, in this embodiment, the first soundproof cover 221 is disposed on the first soundproof pad 211, and the second soundproof cover 222 is disposed on the second soundproof pad 212. Therefore, along the radial direction of fluid flow, the cross-sectional dimension of the second soundproof cover 222 is greater than the cross-sectional dimension of the first soundproof cover 221.

[0073] In this embodiment, since the size of the second sound insulation cover 222 is larger than that of the first sound insulation cover 221, its surface area is also increased accordingly. It can not only adapt to the cross-sectional size of the water outlet pipe 11 at the end of the DC pump 100, but also provide more surfaces for absorbing vibrations and sound waves, so as to improve the sound insulation effect from the end of the DC pump 100 with the loudest noise and reduce the noise level generated when the DC pump is running.

[0074] like Figure 8 As shown, a wire outlet hole 2211 is provided at the end of the first sound insulation cover 221 and at the central axis of the first sound insulation cover 221 .

[0075] like Fig. 9 As shown, a connection hole 2221 through which the water supply pipe 11 extends is provided on the second sound insulation cover 222 .

[0076] In this embodiment, a wire outlet hole 2211 is provided at the end of the first sound insulation cover 221, and a connection hole 2221 through which the water supply pipe 11 extends is provided on the second sound insulation cover 222. Such a design not only ensures the normal operation of the various components, but also makes the line layout more simple and neat, making the components compact and non-interfering with each other.

Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
