[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0040] Hereinafter, a liquid pump component 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0041] like Figure 1 and Figure 3 As shown, the liquid pump component 100 according to the embodiment of the utility model includes a liquid pump 1, a sound insulation cover 2 and a buffer assembly 3. The end 1a of the liquid pump 1 has a pipe structure 11, and the pipe structure 11 may include an inlet pipe and / or an outlet pipe of the liquid pump 1; the sound insulation cover 2 has an installation cavity 21, and the sound insulation cover 2 is formed with a through hole 22 connected to the installation cavity 21. The liquid pump 1 is arranged in the installation cavity 21, and the pipe structure 11 is opposite to the through hole 22; the buffer assembly 3 stops between the liquid pump 1 and the sound insulation cover 2 to separate the liquid pump 1 and the sound insulation cover 2.

[0042] Thus, by arranging the liquid pump 1 in the installation cavity 21, and the buffer assembly 3 abutting between the liquid pump 1 and the soundproof cover 2, the buffer assembly 3 can absorb the vibration generated by the liquid pump 1 to reduce the vibration transmitted to the outside by the liquid pump 1, such as the vibration transmitted to the unit by the liquid pump 1, which is conducive to alleviating the vibration impact of the liquid pump 1 on the soundproof cover 2, or other structures or components arranged adjacent to the liquid pump component 100, and effectively reducing the noise and vibration of the liquid pump 1 during operation. For example, the buffer assembly 3 can reduce the noise generated by the liquid pump 1 from 38dB to 30dB; and the soundproof cover 2 wrapping the liquid pump 1 can effectively block the propagation of noise, that is, the soundproof cover 2 can block the noise inside, thereby effectively reducing the noise transmitted to the outside by the liquid pump 1, reducing the noise of the liquid pump component 100, and improving the stability and sound quality of the liquid pump component 100. Secondly, when the liquid pump component 100 is used in a window air conditioner, it can reduce the noise generated by the window air conditioner, improve the sound quality of the window air conditioner, and improve the user's comfort.

[0043] For example, combined with Figure 1 and Figure 3, take the liquid pump component 100 used in a window air conditioner as an example for explanation, the window air conditioner is hung on the windowsill, the window air conditioner includes an indoor unit part and an outdoor unit part, the indoor unit part is located on the indoor side, and the outdoor unit part is located on the outdoor side, the liquid pump component 100 is arranged on the indoor unit part, and a water collecting pan is arranged in the indoor unit part, the water collecting pan can collect condensed water generated during the operation of the indoor unit part, and the water inlet of the liquid pump component 100 is connected to the water collecting pan, and the water outlet of the liquid pump component 100 is connected to the connecting pipeline, the water outlet and the water inlet of the liquid pump 1 are integrated on the connecting pipe structure 11, and the connecting pipe structure 11 is connected to the connecting pipe and the water collecting pan at the same time, then the liquid pump 1 can pump the water in the water collecting pan to the outside of the water collecting pan, for example, pump it to the outdoors (for example, outdoor environment, outdoor water collecting pan, or outdoor heat exchanger, etc.).

[0044] It can be understood that the liquid pump component 100 is arranged in the indoor part of the window air conditioner. The liquid pump 1 can supply the condensed water collected in the water collection tray to the connecting pipe, and the connecting pipe further supplies the condensed water to the condenser, which can improve the heat exchange capacity of the condenser; or further spray the condensed water onto the surface of other components in the window air conditioner to perform self-cleaning of the window air conditioner; or further filter and atomize the condensed water and discharge it to the indoor side to achieve humidification of the indoor side.

[0045] The liquid pump component 100 includes a liquid pump 1, a soundproof cover 2 and a buffer assembly 3. The soundproof cover 2 has an installation cavity 21, and the soundproof cover 2 is formed with a through hole 22, and the through hole 22 is connected to the installation cavity 21. The liquid pump 1 and the buffer assembly 3 are arranged in the installation cavity 21, and the buffer assembly 3 stops between the liquid pump 1 and the soundproof cover 2. For example, the buffer assembly 3 can wrap the entire liquid pump 1, or wrap part of the surface of the liquid pump 1. The liquid pump 1 has a pipe connection structure 11, and the pipe connection structure 11 is arranged corresponding to the through hole 22, so that the connecting pipeline is connected to the pipe connection structure 11 through the through hole 22. Therefore, when the liquid pump 1 is working, the buffer component 3 can absorb the vibration of the liquid pump 1 to reduce the vibration transmitted from the liquid pump 1 to the sound insulation cover 2, that is, the noise generated between the liquid pump 1 and the sound insulation cover 2 can be reduced. At the same time, the sound insulation cover 2 can effectively seal the working noise generated by the liquid pump 1 in the sound insulation cover 2 to block the transmission of noise. Therefore, by setting the sound insulation cover 2 and the buffer component 3, the influence of noise and vibration during the operation of the liquid pump 1 on the vibration and noise of the window air conditioner can be effectively reduced, thereby improving the user experience of the window air conditioner.

[0046] In the above technical solution, the liquid pump 1 is arranged in the installation cavity 21, and the buffer assembly 3 is stopped between the liquid pump 1 and the soundproof cover 2, so that the buffer assembly 3 can absorb the vibration generated by the liquid pump 1 to reduce the vibration transmitted to the outside by the liquid pump 1, which is conducive to alleviating the vibration impact of the liquid pump 1 on the soundproof cover 2, or other structures or components arranged adjacent to the liquid pump component 100, and effectively reducing the noise and vibration during the operation of the liquid pump 1. And the soundproof cover 2 wraps the liquid pump 1 to effectively block the propagation of noise, thereby effectively reducing the noise and vibration generated by the liquid pump 1, and improving the stability, sound quality and comfort of the liquid pump component 100.

[0047] In the description of this application, "axial direction" can be understood as the axial direction of the liquid pump 1, that is, Figure 3 The extension direction of the central axis 1b of the liquid pump 1; "radial" can be understood as the radial direction of the liquid pump 1, that is, the direction passing through the central axis 1b of the liquid pump 1 on the cross section of the liquid pump 1, the radial direction of the liquid pump 1 is perpendicular to the axial direction of the liquid pump 1.

[0048] In some embodiments of the present application, Figure 3-Figure 5 The liquid pump 1 includes a connected driving part 12 and a cylinder head 13, and the pipe structure 11 is arranged on the side of the cylinder head 13 facing away from the driving part 12. The driving part 12 can provide power, and the cylinder head 12 operates to achieve water pumping; the buffer assembly 3 includes a first buffer member 31, and the first buffer member 31 stops between the driving part 12 and the sound insulation cover 2.

[0049] Optionally, the first buffer member 31 may refer to a structure or material having a buffering and impact absorbing function. For example, the first buffer member 31 may be a rubber member or the like, or may be constructed as a compressible and deformable structure. The first buffer member 31 may absorb the impact of the liquid pump 1 by deformation.

[0050] In the above technical solution, by arranging the first buffer member 31 to stop between the driving part 12 and the sound insulation cover 2, the vibration of the two-liquid pump 1 is partially derived from the vibration of the driving part 12, so that the first buffer member 31 can effectively absorb the vibration generated by the driving part 12 to alleviate the vibration impact of the driving part 12 on the sound insulation cover 2, and effectively reduce the vibration, impact and noise transmitted by the driving part 12 when working.

[0051] In some embodiments of the present application, Figure 3 and Figure 4 The first buffer member 31 includes a plurality of first protrusions 311 sequentially arranged along the axial direction of the driving portion 12 , each first protrusion 311 is formed in a ring shape, and each first protrusion 311 is sleeved on the outer peripheral side of the driving portion 12 , and at least parts of two adjacent first protrusions 311 are spaced apart in the axial direction of the driving portion 12 .

[0052] In the above technical solution, at least part of two adjacent first protrusions 311 are arranged to be spaced apart in the axial direction of the driving part 12, so that there is a certain deformation space between the two adjacent first protrusions 311, so that the first protrusions 311 can absorb vibrations through the deformation process to reduce the noise generated by vibration. Secondly, the first buffer member 31 can reduce the contact area between the liquid pump 1 and the soundproof cover 2, and can further reduce the vibration impact of the liquid pump 1 on the soundproof cover 2, so as to reduce the vibration and noise generated by the liquid pump 1 during operation.

[0053] Optionally, the cross-sectional shape of the first protrusion 311 in the longitudinal section of the driving part 12 is not limited. For example, the cross-sectional shape of the first protrusion 311 may be rectangular, semicircular, or semi-elliptical.

[0054] In some embodiments of the present application, at least two first protrusions 311 are spaced apart in the axial direction; and / or at least two adjacent first protrusions 311 are connected at one end adjacent to each other, so that the plurality of first protrusions 311 are spirally shaped.

[0055] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0056] For example, the first buffer 31 includes a plurality of first protrusions 311 sequentially spaced along the axial direction of the driving part 12, that is, the plurality of first protrusions 311 are formed into an annular structure, and are sequentially spaced along the axial direction of the driving part 12 on the outer peripheral side of the driving part 12, and the plurality of first protrusions 311 are stopped between the liquid pump 1 and the soundproof cover 2. Alternatively, the plurality of first protrusions 311 are sequentially spaced along the axial direction of the driving part 12, and the ends of two adjacent first protrusions 311 adjacent to each other are connected end to end, so that the plurality of first protrusions 311 are formed into a spiral structure.

[0057] In the above technical solution, by arranging at least two first protrusions 311 spaced apart along the axial direction, and / or connecting at least one end of two adjacent first protrusions adjacent to each other, the multiple first protrusions 311 can have a variety of structural forms, so that the first protrusions 311 can better adapt to the structure of the driving part 12, so that the first protrusions 311 can better buffer and absorb the vibration generated by the liquid pump 1; at the same time, the arrangement of the multiple first protrusions 311 is flexible, which is convenient for improving the applicability and practicality of the liquid pump component 100.

[0058] Optionally, combined Figure 6 and Figure 7, a plurality of limiting ribs 20 are formed on the inner wall of the soundproof cover 2, and at least two limiting ribs 20 are arranged at intervals along the axial direction; and / or, at least two adjacent limiting ribs 20 are connected at one end adjacent to each other, so that the plurality of limiting ribs 20 are spiral-shaped, and at least one first protrusion 311 is provided between two adjacent limiting ribs 20. Among them, the limiting ribs 20 and the first protrusion 311 are matched with each other in the radial direction of the driving part 12, so that the limiting ribs 20 can limit the movement or deformation of the first protrusion 311 in the radial direction, so that the first protrusion 311 can maintain a larger contact area to cooperate with the soundproof cover 2, which is beneficial to improving the first buffer 31 The ability to absorb the vibration of the liquid pump 1 is beneficial to reducing the noise and vibration of the liquid pump 1.

[0059] In some embodiments of the present application, Figure 4 The first buffer 31 also includes a main body 312, which is formed into a cylindrical structure and sleeved on the outer peripheral side of the driving part 12, and all the first protrusions 311 are integrally formed on the outer peripheral wall of the main body 312. Therefore, the main body 312 can improve the stability of the first buffer 31 on the driving part 12, and improve the stability of the contact between the first protrusion 311 and the soundproof cover 2, so that the first protrusion 311 can better dampen the vibration between the buffer pump 1 and the soundproof cover 2.

[0060] In some embodiments of the present application, the first buffer member 31 further includes at least one second protrusion, and the second protrusion is arranged crosswise with the at least one first protrusion 311 .

[0061] Optionally, the first protrusion 311 , the second protrusion and the main body 312 are integrally formed on the outer peripheral wall of the main body 312 .

[0062] In the above technical solution, by arranging the second protrusion to cross at least one first protrusion 311, the structural stability of the first protrusion 311 can be improved to reduce the deformation of the first protrusion 311, and ensure that there is a suitable contact area between the first protrusion 311 and the soundproof cover 2, so that the first protrusion 311 can play a better buffering role. Secondly, the second protrusion can increase the contact area between the first buffer 31 and the isolation cover, and can further improve the vibration absorption ability of the first buffer 31, so as to reduce the vibration and noise generated when the liquid pump 1 is working.

[0063] In some embodiments of the present application, Figure 3 The buffer assembly 3 includes a second buffer member 32 , and the second buffer member 32 is abutted between the cylinder head 13 and the sound insulation cover 2 .

[0064] Optionally, the second buffer member 32 may refer to a structure or material having a buffering and impact absorbing function. For example, the second buffer member 32 may be a rubber member, a sponge, or the like, or may be constructed as a compressible and deformable structure. The second buffer member 32 may absorb the impact of the liquid pump 1 by deformation.

[0065] In the above technical solution, by arranging the second buffer member 32 to stop between the cylinder head 13 and the sound insulation cover 2, the second buffer member 32 can effectively absorb the vibration generated by the driving part 12 to alleviate the vibration impact of the cylinder head 13 on the sound insulation cover 2, and effectively reduce the vibration and impact transmitted by the cylinder head 13 when working.

[0066] In some embodiments of the present application, Figure 3 and Figure 4 , the cross-sectional shape of the cylinder head 13 has at least one edge, and the flexibility of the second buffer 32 is better than that of the first buffer 31. Therefore, the second buffer 32 has a good deformation ability and can better adapt to the complex structure of the outer peripheral wall of the cylinder head 13 to ensure that the second buffer 32 can be stably arranged between the cylinder head 13 and the soundproof cover 2, and the second buffer 32 is convenient to be arranged on the cylinder head 13.

[0067] For example, combined with Figure 4 The cylinder head 13 has an end shell, which is located on the side of the cylinder head 13 away from the driving part 12. A plurality of through holes are provided on the periphery of the end shell so that the end shell can be connected to the corresponding structure of the cylinder head 13 by screws or the like. Thus, a plurality of raised angular structures are formed on the outer peripheral wall of the cylinder head 13.

[0068] In some embodiments of the present application, Figure 3-Figure 5 In the cross section of the driving portion 12, at least part of the orthographic projection of the cylinder head 13 is located outside the orthographic projection range of the driving portion 12, the first buffer 31 is formed as a cylindrical structure, the second buffer 32 is connected to the first buffer 31, and the second buffer 32 is formed as an open ring; or, the second buffer 32 is spaced apart from the first buffer 31, and the second buffer 32 is formed as a ring.

[0069] In the above technical scheme, by setting the second buffer member 32 connected to the first buffer member 31, the stability of the buffer assembly 3 on the liquid pump 1 can be improved, which is beneficial to improving the vibration absorption effect of the buffer assembly 3. At the same time, since the second buffer member 32 is an open ring, it is convenient for the component formed by the connection of the first buffer member 31 and the second buffer member 32 to be smoothly assembled with the liquid pump 1. For example, the liquid pump 1 can also be axially inserted into the first buffer member 31 through the opening of the second buffer member 32; or, by setting the second buffer member 32 and the first buffer member 31 to be spaced apart, it is convenient to simplify the processing difficulty and installation difficulty of the first buffer member 31 and the second buffer member 32, and facilitate the assembly of the liquid pump component 100.

[0070] It should be noted that the "open ring" described herein refers to a ring with an opening, i.e., a non-closed ring, wherein "ring" is to be understood in a broad sense, i.e., not limited to a "circular ring", for example, it can also be a "polygonal ring", etc. Thus, the first buffer 31 is formed into an open ring, which facilitates the installation of the first buffer 31 on the cylinder head 13 through the opening, thereby simplifying the installation difficulty.

[0071] Optionally, the second buffer member 32 is formed into a ring shape, and the second buffer member 32 can be an integral structure or a split structure. For example, the second buffer member 32 can be an integral structure, and the second buffer member 32 is formed into a ring structure connected as a whole; or, the second buffer member 32 can be a split structure, and the second buffer member 32 can be composed of a plurality of arc-shaped parts, such as the second buffer member 32 can be composed of two arc-shaped parts spliced ​​together, to facilitate the installation of the second buffer member 32.

[0072] In some embodiments of the present application, the first buffer 31 is a rubber member or a silicone member, and the second buffer 32 is a sponge member. In the above technical solution, by setting the first buffer 31 as a rubber member or a silicone member, the first buffer 31 has a better ability to absorb vibration and deformation, so that the first buffer 31 can better adapt to the structure of the driving part 12, and by setting the second buffer 32 as a sponge member, the second buffer 32 has a better deformation ability, so as to better adapt to the structure of the cylinder head 13 to ensure the reliable installation of the second buffer 32, and the sponge member has a good ability to be easily formed, which is convenient for processing and can better adapt to the structure of the cylinder head 13. Secondly, the material cost of the first buffer 31 and the second buffer 32 is relatively low, which is conducive to reducing the cost of the liquid pump component 100.

[0073] In some embodiments of the present application, the liquid pump 1 is a diaphragm pump. Therefore, the diaphragm pump has good stability in liquid delivery and stability in use, and the flow channel and other structures of the diaphragm pump for delivering liquid are isolated from the outside world, which can reduce the contamination of the delivered liquid by the outside world, thereby improving the reliability and safety of the liquid pump 1 in delivering liquid, and facilitating the consideration of both miniaturization design and greater water outlet pressure.

[0074] It should be noted that the diaphragm pump includes a driving part 12 and a cylinder head 13, the driving part 12 includes a motor, and a diaphragm and an eccentric wheel are arranged in the cylinder head 13. Compared with the common liquid pump 1, the noise source of the diaphragm pump is more diverse. Therefore, by arranging the first buffer 31 to stop between the driving part 12 and the sound insulation cover 2, and the second buffer 32 to stop between the cylinder head 13 and the sound insulation cover 2, the first buffer 31 can adapt to the noise source of the driving part 12, and the second buffer 32 can adapt to the noise source of the cylinder head 13, which can effectively reduce the noise of the corresponding part of the diaphragm pump, thereby improving the ability of the buffer assembly 3 to absorb vibration and noise.

[0075] In some embodiments of the present application, Figure 1 and Figure 5 The end 1a of the liquid pump 1 also has a pressure regulating valve 14 spaced apart from the pipe structure 11, and the pressure regulating valve 14 is arranged in the installation cavity 21 and opposite to the through hole 22. Therefore, the pressure regulating valve 14 can be operated through the through hole 22 to adjust the pressure and / or flow of the liquid pump 1.

[0076] In some embodiments of the present application, Figure 1 and Figure 6 The soundproof cover 2 is also formed with a wire hole 23 connected to the installation cavity 21. The soundproof cover 2 has a partition 24. One side of the partition 24 participates in forming the through hole 22, and the other side of the partition 24 participates in forming the wire hole 23.
