Description

Base unit, oral care device and vibration reduction structure TECHNICAL FIELD

[0001] The present application relates to the technical field of oral care, in particular to a base unit, an oral care device and a vibration reduction structure. BACKGROUND

[0002] In the related art, a waterpik uses a motor to drive a water pump, thereby generating high-speed water flow or pulse water flow, which can effectively clean food residues and bacteria in hard-to-clean areas of teeth and gums.

[0003] However, the motor and the water pump are often directly connected to the outer shell of the base unit. During use, the operation of the motor and the water pump drives the outer shell to produce noise, affecting the user experience.

[0004] SUMMARY

[0005] The purpose of the present application is to provide a base unit, an oral care device and a vibration reduction structure, which can reduce the vibration and noise of the base unit and improve the user experience.

[0006] To achieve the above purpose, the present application provides a base unit, comprising:

[0007] a main shell having a receiving chamber;

[0008] a first bearing member located in the receiving chamber, the first bearing member being connected to the main shell and dividing the receiving chamber into a first cavity located above and a second cavity located below;

[0009] a first power assembly connected to the first bearing member and suspended in the second cavity.

[0010] The technical solution provided by the present application is that the first power assembly is connected to the first bearing member and suspended in the second cavity. That is, the first power assembly is at a predetermined height from the bottom of the main shell, and the first power assembly is suspended relative to the bottom of the main shell. In this way, an air or space gap can be formed between the first power assembly and the bottom of the main shell, which can act as a vibration isolation layer to prevent the vibration of the first power assembly from being directly transmitted to the bottom of the main shell in contact with the base unit placement table, thereby reducing the vibration transmission to the main shell. At the same time, when the first power assembly is running, the vibration generated by the first power assembly first acts on the first bearing member instead of being directly transmitted to the main shell. In this way, the first bearing member deforms to absorb vibration energy when subjected to vibration, thereby reducing the vibration transmission of the first power assembly to the main shell through the first bearing member. In this way, with the reduction of vibration on the main shell, the noise generated by the main shell due to vibration can be reduced, thereby improving the user experience.

[0011] To achieve the above object, the application further provides a base unit, comprising:

[0012] a main housing having a receiving chamber;

[0014] a first power assembly connected to the first connecting member and suspended in the receiving chamber.

[0015] To achieve the above object, the application further provides an oral care device, comprising at least a base unit and an oral cleaner, wherein the base unit is communicated with the oral cleaner through a delivery pipeline, the base unit is capable of delivering liquid to the oral cleaner through the delivery pipeline so that the liquid is sprayed out through a cleaning head of the oral cleaner.

DETAILED DESCRIPTION

[0039] With the development of oral cleaning devices, more and more oral cleaning devices with different functions have been produced, such as oral irrigators with only flushing function, and oral irrigators with both flushing function and brushing function. When performing the flushing function, both of the above-mentioned devices need to provide water flow from the base unit to output water flow impact, so as to flush away food residues, bacteria, tartar, stains and other substances harmful to tooth health attached to the teeth and gums, so as to achieve the effect of oral health care and nursing.

[0040] In the related art, in order to fix the motor and the water pump, the motor and the water pump are usually directly connected with the outer shell of the base unit. When conveying water flow, the base unit needs to drive the water pump by the power of the motor to pump and drain water. During the operation of the motor and the water pump, vibration and noise are generated. Therefore, the vibration of the motor and the water pump is directly transmitted to the outer shell, thereby driving the outer shell to vibrate together, aggravating the generation of noise and affecting the user's experience.

[0041] In view of the above technical problems, the present inventors think that the motor and the water pump are connected with the inner shell through the connecting arm, so as to suspend the motor and the water pump by the connecting arm, avoid the vibration of the motor and the water pump being directly transmitted to the outer shell, and further reduce the transmission of the vibration of the motor and the water pump by using the deformation of the connecting arm which is in an elongated shape and has a curved portion, thereby further reducing the generation of noise and improving the user's experience. At the same time, the applicant also coats soft glue between the connecting arm and the inner shell, so as to absorb and reduce the vibration transmitted from the motor and the water pump to the outer shell by using the good elasticity and damping characteristics of the soft glue, thereby further reducing the noise and improving the operation stability of the base unit.

[0042] To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application.

[0043] The base unit 1000 provided by the present application can be used as a separate component in cooperation with the oral cleaner 2000 to provide liquid for rinsing for the oral cleaner 2000. Of course, the base unit 1000 can also be integrated with a charging module, and the base unit 1000 charges the oral cleaner 2000 through the charging module, which is not limited in the present application.

[0044] Please refer to FIGS. 1-2, in an implementable embodiment, the base unit 1000 can at least include a main shell 100, which serves as the main body of the base unit 1000, and can support and protect other components of the base unit 1000 except the main shell 100. The main shell 100 can be a hollow structure, and an accommodating cavity 110 is formed inside the main shell 100.

[0045] In the present embodiment, the base unit 1000 can further include a first bearing member 200 and a first power assembly 300. The first bearing member 200 is located in the accommodating cavity 110, and is connected with the main shell 100 and separates the accommodating cavity 110 into a first cavity 111 located above and a second cavity 112 located below. The first cavity 111 can be used to accommodate a control assembly of the base unit 1000, and the second cavity 112 can be used to accommodate the first power assembly 300, so that when the first power assembly 300 or the pipeline connected thereto accidentally leaks liquid, the possibility of liquid seeping into the first cavity 111 can be reduced due to the first cavity 111 being located above the second cavity 112, and the spread of failure can be avoided.

[0046] The first power assembly 300 serves as the power source of the base unit 1000, and can extract and discharge liquid based on the control of the control assembly. The first power assembly 300 is connected with the first bearing member 200 and suspended in the second cavity 112. That is, the first power assembly 300 has a predetermined height from the bottom of the main shell 100, and is suspended relative to the bottom of the main shell 100. In this way, an air or space gap can be formed between the first power assembly 300 and the bottom of the main shell 100, which can serve as a vibration isolation layer to avoid the vibration of the first power assembly 300 being directly transmitted to the bottom of the main shell 100 in contact with the tabletop on which the base unit 1000 is placed, thereby reducing the vibration transmission to the main shell 100.

[0047] Meanwhile, when the first power assembly 300 is running, the vibration generated by the first power assembly 300 first acts on the first bearing member 200 instead of being directly transmitted to the main shell 100. In this way, the vibration energy can be absorbed by the deformation of the first bearing member 200 when the vibration occurs, thereby reducing the vibration transmission of the first power assembly 300 to the main shell 100 through the first bearing member 200. In this way, as the vibration on the main shell 100 is reduced, the main shell 100 and the noise generated by the vibration can be reduced, thereby improving the user's experience.

[0048] It should be noted that the upward and downward directions defined in the present application refer to the upward and downward directions in the placement perspective of the base station unit 1000 as shown in FIG. 1, i.e., the upward and downward directions in the normal use state of the base station unit 1000.

[0049] In an implementable embodiment, the base station unit 1000 can further include a liquid storage module 500, and the first power assembly 300 is configured to extract the liquid in the liquid storage module 500 and discharge the liquid to the oral cavity cleaner 2000, thereby realizing the oral cavity flushing function.

[0050] In actual application, the liquid storage module 500 can be a liquid storage cavity formed by the main shell 100 and having the function of containing liquid. The liquid storage module 500 can also be a separate water tank that is detachably mounted on the main shell 100. For example, the main shell 100 has a recessed accommodation groove from the top for placing the liquid storage module 500, and the main shell 100 is detachably mounted in the accommodation groove. When the liquid storage module 500 is mounted in the accommodation groove, the first power assembly 300 can be in communication with the inside of the liquid storage module 500, so as to extract the liquid in the liquid storage module 500. The accommodation groove can limit the main shell 100 to form an L-shaped structure, and correspondingly, the accommodation chamber 110 can also be L-shaped. The first cavity 111 can be formed by the upper part of the vertical cavity of the L-shaped accommodation chamber 110, the second cavity 112 can be formed by the lower part of the vertical cavity of the L-shaped accommodation chamber 110 and the horizontal cavity of the accommodation chamber 110, and the first power assembly 300 can extend from the lower part of the vertical cavity of the accommodation chamber 110 to the horizontal cavity of the accommodation chamber 110.

[0051] As shown in FIGS. 3-6, the first load bearing member 200 can include a support 210, a first connecting member 220, and one or more first connecting arms 230 in one embodiment. The support 210 is connected to the main housing 100 to connect the first load bearing member 200 to the main housing 100. The support 210 has a first gap 211 extending through the support 210, and the first cavity 111 can communicate with the second cavity 112 through the first gap 211. The first connecting member 220 is at least partially located in the first gap 211, and the first connecting member 220 is connected to the support 210 by the first connecting arms 230, and the first power assembly 300 is connected to the first connecting member 220. The first connecting arms 230 can deform under stress to absorb vibration energy and reduce the vibration transmission from the first power assembly 300 to the main housing 100 through the first load bearing member 200. The first connecting member 220 connected to the first power assembly 300 is connected to the support 210 by the first connecting arms 230, and there is a gap between the first connecting member 220 and the support 210, which can effectively isolate vibration and reduce the vibration transmission between the first power assembly 300 and the main housing 100. Meanwhile, the first connecting arms 230 are preferably two or more, and the first connecting member 220 is connected to the support 210 by at least two first connecting arms 230 to avoid unstable single-sided connection and ensure the stability of the connection between the first power assembly 300 and the support 210.

[0052] In this embodiment, the first connecting arms 230 can have an elongated structure, and the first connecting arms 230 can be made of hard rubber. The first connecting arms 230 can deform to absorb vibration energy and reduce the vibration transmission from the first power assembly 300 to the main housing 100 by using their shape characteristics. Meanwhile, the first connecting arms 230 made of hard rubber can also have a certain strength to avoid the problems of breaking under stress and permanent deformation. Of course, the first connecting arms 230 can also be made of other materials that have a certain strength and can deform to a certain extent.

[0053] In practical applications, the support member 210 can be directly or indirectly connected to the main housing 100. When the support member 210 is directly connected to the main housing 100, the main housing 100, the support member 210, the first connecting member 220, and the first connecting arm 230 can be integrally formed by injection molding or the like, thereby simplifying the production process, reducing the production cost, and at the same time ensuring the stability and reliability of the connection between the main housing 100, the support member 210, the first connecting member 220, and the first connecting arm 230. Of course, the main housing 100 can also be integrally formed with a part of the support member 210, the first connecting member 220, and the first connecting arm 230, or the main housing 100, the support member 210, the first connecting member 220, and the first connecting arm 230 are separately formed and then connected to each other.

[0054] Further, the first connecting arm 230 can have at least one bending portion, that is to say, the first connecting arm 230 has a bending design, so that the deformation range of the first connecting arm 230 can be further increased through the bending design, and the vibration damping effect of the first connecting arm 230 can be improved.

[0055] In practical applications, the bending portion of the first connecting arm 230 can have one, two, three, or four, etc. When the first connecting arm 230 has one bending portion, the first connecting arm 230 can be in a "J" shape as shown in FIG. 5.

[0056] As shown in FIGS. 5 to 6, in a feasible implementation manner, the first connecting member 220 can include an intermediate frame 221 and a first connecting column 222. The first power component 300 is connected to the first connecting column 222, and the number of the first connecting columns 222 can be one, two, or more. The first connecting columns 222 are preferably provided with two or more. At least two first connecting columns 222 are connected to the edge of the intermediate frame 221, and at least two first connecting arms 230 are connected to at least two first connecting columns 222 through the intermediate frame 221. Thus, compared with the manner in which each first connecting column 222 is respectively connected to the support member 210 through the first connecting arm 230, in this application, by connecting at least two first connecting columns 222 to the intermediate frame 221 and connecting the intermediate frame 221 to the support member 210 through the first connecting arm 230, the structure of the first bearing member 200 can be simplified.

[0057] At the same time, the first connecting column 222 connected to the first power component 300 is connected to the edge of the intermediate frame 221, that is to say, the intermediate frame 221 does not completely surround the first connecting column 222. In this way, there is a non-connection area between the first connecting column 222 and the intermediate frame 221 in the circumferential direction, which can further reduce the vibration transmission of the first power component 300 through the circumferential direction of the first connecting column 222.

[0058] In practical applications, as shown in FIG. 7, the top of the first power assembly 300 can be provided with a mounting column 311, the first connecting column 222 is provided with an inner cavity for accommodating the mounting column 311, and the mounting column 311 can enter the inner cavity of the first connecting column 222 and be connected by clamping, bonding, interference or screw fastening.

[0059] The shape of the first notch 211 can be triangular, circular, square or any other shape.

[0060] As shown in FIGS. 3 and 4, taking the first notch 211 as an example, the number of the first connecting column 222 and the first connecting arm 230 can be the same, and at least two first connecting columns 222 and at least two first connecting arms 230 are arranged alternately and arranged in a ring array about the axis of the first notch 211. That is, there is a first connecting arm 230 between the two adjacent first connecting columns 222, and the two adjacent first connecting columns 222 are symmetrically arranged about the first connecting arm 230 located between the two adjacent first connecting columns 222. In this way, the uniformity and stability of the first connecting arm 230 supporting the first connecting piece 220 can be ensured, and at the same time, the vibration from the first power assembly 300 can be uniformly transmitted to the first notch 211 through the first connecting column 222 and the first connecting arm 230, thereby uniformly distributed on the main shell 100, avoiding the problem of excessive noise caused by vibration concentration.

[0061] It should be pointed out that the first notch 211 can be a complete circle. However, in actual design process, the first notch 211 is often limited by the components inside the main shell 100 to form a corresponding inwardly extending or outwardly extending area to form a circular shape. The complete circle and the circular shape are both the above-mentioned substantially circular shape.

[0062] The number of the first connecting column 222 and the first connecting arm 230 can be two, three, four, five, etc. Taking the number of the first connecting column 222 and the first connecting arm 230 as an example, the three first connecting arms 230 are respectively connected with the side walls of the middle frame 221 between the adjacent two first connecting columns 222.

[0063] In practical applications, the middle frame 221 can be triangular, the three first connecting columns 222 are respectively connected with the three vertices of the middle frame 221, and the three first connecting arms 230 are respectively connected with the middle points of the three sides of the middle frame 221. The three sides of the middle frame 221 can also be inwardly recessed arcs, so that the middle frame 221 also has a certain deformation ability, thereby absorbing vibration energy through the deformation of the middle frame 221, thereby reducing the vibration transmission of the first power assembly 300 to the main shell 100 through the first bearing member 200.

[0064] In order to further reduce the vibration transmission of the first power assembly 300 to the main housing 100 through the first bearing member 200, as shown in FIG. 8 and FIG. 9, in an implementable embodiment, the first bearing member 200 can further comprise a first covering member 240 made of soft glue, wherein the soft glue is a material with elasticity and softness, which can be made of various different high molecular polymers, such as natural or synthetic rubber, silicone rubber, TPE (thermoplastic elastomer), TPU (thermoplastic polyurethane), soft PVC, etc. The first covering member 240 at least partially covers at least one of the support 210, the first connecting member 220 and the first connecting arm 230. In this way, when the first power assembly 300 transmits vibration through the first connecting member 220, the first connecting arm 230 and the support 210, the first covering member 240 can absorb the vibration by using its own elasticity and damping properties, thereby reducing the vibration transmission. At the same time, the first covering member 240 can connect the support 210, the first connecting member 220 and the first connecting arm 230 to each other to ensure the stability between the support 210, the first connecting member 220 and the first connecting arm 230, avoid breakage or permanent deformation damage caused by vibration, and improve the service life of the first bearing member 200.

[0065] In actual application, after the support 210, the first connecting member 220 and the first connecting arm 230 are integrally formed, or after the separately designed ones are connected to each other, the first covering member 240 can cover at least one of the support 210, the first connecting member 220 and the first connecting arm 230 by means of secondary injection molding or sleeving, etc.

[0066] The above-mentioned first covering member 240 can partially fill the hollowed-out area between the support 210, the first connecting member 220 and the first connecting arm 230.

[0067] The above-mentioned first covering member 240 can also completely fill the hollowed-out area in the support 210, the first connecting member 220 and the first connecting arm 230, and accordingly, the outer peripheral surface of the support 210 is seamlessly connected to the inner wall surface of the main housing 100. In this way, the first bearing member 200 can isolate the first cavity 111 and the second cavity 112 from each other, which can further avoid the possibility of the liquid accidentally leaked in the second cavity 112 entering the first cavity 111, and reduce the spread of faults.

[0068] In actual application, the first covering member 240 can completely cover the intermediate frame 221 and the first connecting arm 230 inside, or the first covering member 240 can only cover the side surface and the bottom surface of the intermediate frame 221 and the first connecting arm 230. The first covering member 240 can only cover the side surface of the first connecting column 222, so that the vibration transmitted by the first connecting column 222 in the circumferential direction can be damped by the first covering member 240. In order to avoid the disconnection of the first covering member 240 and the first connecting column 222, the outer wall surface of the first connecting column 222 is provided with an outwardly protruding annular flange, and the first covering member 240 is only covered below the annular flange. In this way, when the first power assembly 300 exerts a downward force on the first connecting column 222, the first covering member 240 can abut against the annular flange to share the stress, thereby reducing the possibility of disconnection of the first covering member 240 and the first connecting column 222.

[0069] As shown in FIGS. 6, 8, 10-12, in an implementable embodiment, the support member 210 can be provided with a plurality of fixing holes 212, which are arranged at intervals around the edge of the first notch 211. The first covering member 240 fills the plurality of fixing holes 212, so that the contact area between the first covering member 240 and the support member 210 can be increased, the adhesion between the first covering member 240 and the support member 210 can be increased, the possibility of disconnection of the first covering member 240 during multiple deformations can be avoided, and the stability and reliability of the first covering member 240 can be improved.

[0070] In actual application, the plurality of fixing holes 212 can be arranged in an annular array around the edge of the first notch 211, or the plurality of fixing holes 212 can be arranged at least partially at unequal intervals around the first notch 211, which is not limited in the present application.

[0071] It can be understood that when the support member 210 is provided with the fixing hole 212, the fixing hole 212 can be understood as a hollowed-out area on the support member 210. Accordingly, when the first bearing member 200 needs to isolate the first cavity 111 and the second cavity 112 from each other, the first covering member 240 not only needs to fill the hollowed-out areas in the support member 210, the first connecting member 220 and the first connecting arm 230 bracket, but also needs to fill the fixing hole 212, i.e. fill the hollowed-out area on the support member 210.

[0072] Further, the support member 210 can be provided with a stepped groove 213, which is arranged around the edge of the first gap 211 and has an inner wall surface in communication with the first gap 211, and a plurality of fixing holes 212 are formed in the groove bottom of the stepped groove 213. The first covering member 240 fills the stepped groove 213, thereby further increasing the contact area between the first covering member 240 and the support member 210 and increasing the adhesion between the first covering member 240 and the support member 210. At the same time, the arrangement of the stepped groove 213 can also make the first covering member 240 substantially flush with the top surface and the bottom surface of the support member 210, so as to ensure the overall aesthetics of the first bearing member 200.

[0073] As shown in FIG. 12, in an implementable embodiment, the bottom surface of the first covering member 240 is provided with an annular groove 241, which is located in the first gap 211 and arranged around the edge of the first gap 211. A plurality of reinforcing ribs 242 are arranged in the annular groove 241 in an annular array, thereby increasing the strength of the first covering member 240 through the reinforcing ribs 242, so that the first covering member 240 can better withstand long-term or repeated loads, thereby prolonging its service life, and the first covering member 240 with higher strength can provide better support for the first power assembly 300, reduce deformation under high load conditions, and thus improve the stability of the first bearing member 200.

[0074] Regarding the specific structure of the first power assembly 300, as shown in FIG. 7, in an implementable embodiment, the first power assembly 300 can include a driving module 310, a transmission module 320, and a water pumping module 330. The top end of the driving module 310 is connected to the first bearing member 200, and the bottom end of the driving module 310 is connected to the water pumping module 330 through the transmission module 320, so that the driving module 310 can drive the water pumping module 330 to operate through the transmission module 320 to extract the liquid in the liquid storage module 500 and discharge it.

[0075] In this embodiment, the driving module 310 can be connected with the water pumping module 330 through the transmission module 320 to form an integral whole, which can be integrally installed on or detached from the base station unit 1000. The driving module 310 is located in the vertical cavity of the second cavity 112, the transmission module 320 is located at the junction of the vertical cavity and the horizontal cavity of the second cavity 112, and the water pumping module 330 is located in the horizontal cavity of the second cavity 112.

[0076] In actual application, the driving module 310 can be a motor, the transmission module 320 can be a gear box, and the water pumping module 330 can be a water pump. A motor frame 312 is installed on the motor, and correspondingly, the mounting column 311 is formed on the motor frame 312.

[0077] In order to ensure that the position of the water pumping module 330 is relatively fixed, and to avoid affecting the normal operation of the water pumping module 330, the water pumping module 330, or the connection between the water pumping module 330 and the transmission module 320 is connected to the main shell 100 through the second bearing member 400. At the same time, the second bearing member 400 limits the position of the first power assembly 300 at one end of the water pumping module 330, and can also avoid large amplitude vibration of the water pumping module 330, thereby reducing vibration and noise.

[0078] In actual application, in order to ensure that the first power assembly 300 is suspended in the second cavity 112, the second bearing member 400 is connected to the part of the main shell 100 above or beside the water pumping module 330, so that the water pumping module 330 is still suspended relative to the bottom of the main shell 100.

[0079] Regarding the specific structure of the second bearing member 400, two implementable embodiments are provided for reference.

[0080] Embodiment one, as shown in FIG. 13 and FIG. 14, the second bearing member 400 includes a second connecting piece 410 and a second connecting arm 420, wherein the second connecting piece 410 is connected to the water pumping module 330, or the second connecting piece 410 is connected to the connection between the water pumping module 330 and the transmission module 320. One end of the second connecting arm 420 is connected to the second connecting piece 410, and the other end of the second connecting arm 420 is connected to the main shell 100. And the second connecting arm 420 has at least one bending part.

[0081] In this embodiment, the second connecting arm 420 can have an elongated structure, and the second connecting arm 420 can be made of hard rubber material. The second connecting arm 420 utilizes its shape characteristics to achieve deformation, thereby absorbing vibration energy and reducing vibration transmission from the water pumping module 330 to the main shell 100. At the same time, the second connecting arm 420 can be made of hard rubber material, which has a certain strength, avoiding the problems of breaking under stress and permanent deformation. Of course, the second connecting arm 420 can also be made of other materials that have a certain strength and can produce a certain degree of deformation.

[0082] In practical applications, the second connecting member 410 can be sleeve-shaped, and the second connecting member 410 is sleeved on the pump water module 330 or the connection between the pump water module 330 and the transmission module 320. The second connecting member 410 can also be formed into a sleeve shape by splicing two circular arc members with each other, and the present application does not make specific limitation on this. The second connecting arm 420 can be directly connected with the main shell 100 or indirectly connected with the main shell 100. When the second connecting arm 420 is directly connected with the main shell 100, the main shell 100 and the second connecting arm 420 can be integrally formed by injection molding or the like, so as to simplify the production process and reduce the production cost. Of course, when the second connecting arm 420 is directly connected with the main shell 100, the second connecting arm 420 and the main shell 100 can also be connected by means of clamping, hot melting, gluing and threaded fastening, and the present application does not make specific limitation on this.

[0083] Further, the second connecting arm 420 can have at least one bending portion, that is, the second connecting arm 420 has a bending design, so as to further increase the deformation range of the second connecting arm 420 through the bending design and improve the damping effect of the second connecting arm 420.

[0084] Embodiment two, as shown in FIGS. 15-16, the second bearing member 400 includes a third connecting member 430 and a connecting seat 440, wherein the third connecting member 430 is connected with the pump water module 330 or the connection between the pump water module 330 and the transmission module 320; the third connecting member 430 is connected with the main shell 100 through the connecting seat 440.

[0085] When the pump water module 330 operates, the vibration generated at the pump water module 330 is first applied to the second bearing member 400, rather than being directly transmitted to the main shell 100. In this way, since the second bearing member 400 deforms when subjected to vibration, this deformation can absorb vibration energy, thereby reducing the vibration transmission of the pump water module 330 to the main shell 100 through the second bearing member 400. In this way, as the vibration on the main shell 100 is reduced, the noise generated by the vibration of the main shell 100 can be reduced, thereby improving the user experience.

[0086] In practical applications, the third connecting member 430 can be sleeve-shaped, and the third connecting member 430 is sleeved on the pump water module 330 or the connection between the pump water module 330 and the transmission module 320. The third connecting member 430 can also be formed into a sleeve shape by splicing two circular arc members with each other, and the present application does not make specific limitation on this.

[0087] As shown in FIGS. 16-18, in an implementable embodiment, the connecting seat 440 can include a seat body 441, a second connecting column 442, and a third connecting arm 443, the number of the third connecting arm 443 can be one, two, or more, wherein the seat body 441 is connected with the main shell 100, and the seat body 441 is provided with a second gap 4411. The second connecting column 442 is at least partially located in the second gap 4411, one end of the second connecting column 442 is connected with the seat body 441 through the third connecting arm 443, and the other end of the second connecting column 442 is connected with the third connecting piece 430. The vibration energy is absorbed by the deformation of the third connecting arm 443, thereby reducing the vibration transmission of the pump water module 330 to the main shell 100 through the connecting seat 440.

[0088] Further, the number of the third connecting arm 443 is preferably two or more, the second connecting column 442 is connected with the seat body 441 through at least two third connecting arms 443, and there is a gap between the second connecting column 442 and the seat body 441, which can effectively isolate the vibration and reduce the vibration transmission between the second connecting column 442 and the main shell 100. At the same time, the second connecting column 442 is connected with the seat body 441 by at least two third connecting arms 443, which avoids the unstable situation of unilateral connection and ensures the stability of the connection between the seat body 441 and the second connecting column 442.

[0089] In the present embodiment, the third connecting arm 443 can have an elongated structure, and the third connecting arm 443 can be made of hard rubber material. The third connecting arm 443 utilizes its shape characteristics to deform, thereby absorbing vibration energy and reducing the vibration transmission from the pump water module 330 of the first power assembly 300 to the main shell 100. At the same time, the third connecting arm 443 made of hard rubber material can also have a certain strength, which can avoid the problems of breaking under stress and permanent deformation. Of course, the third connecting arm 443 can also be made of other materials that have a certain strength and can produce a certain degree of deformation.

[0090] In actual application, the seat body 441, the second connecting column 442, and the third connecting arm 443 can all be made of hard rubber material and integrally formed by injection molding, thereby simplifying the production process, reducing the production cost, and also ensuring the stability and reliability of the connection between the seat body 441, the second connecting column 442, and the third connecting arm 443.

[0091] Further, the third connecting arm 443 can have at least one bending portion, that is, the third connecting arm 443 has a bending design, thereby further increasing the deformation range of the third connecting arm 443 through the bending design and improving the vibration reduction effect of the third connecting arm 443.

[0092] As shown in FIGS. 16-20, in an implementable embodiment, the connecting seat 440 can further include a second covering member 444 made of soft rubber; the second covering member 444 at least partially covers at least one of the seat body 441, the second connecting column 442 and the third connecting arm 443. It should be noted that soft rubber is a material with elasticity and softness, which can be made of various different high-molecular polymers, such as natural or synthetic rubber, silicone rubber, TPE (thermoplastic elastomer), TPU (thermoplastic polyurethane), soft PVC, etc.

[0093] When the pump water module 330 of the first power assembly 300 transmits vibration through the second connecting column 442, the third connecting arm 443 and the seat body 441, the second covering member 444 can absorb the vibration by using its own elasticity and damping characteristics, thereby reducing vibration transmission. At the same time, the second covering member 444 can connect the second connecting column 442, the third connecting arm 443 and the seat body 441 to each other, so as to ensure the stability between the second connecting column 442, the third connecting arm 443 and the seat body 441, avoid breakage or permanent deformation damage caused by vibration, and improve the service life of the second bearing member 400.

[0094] In actual application, after the second connecting column 442, the third connecting arm 443 and the seat body 441 are integrally formed, or after the separately designed second connecting column 442, the third connecting arm 443 and the seat body 441 are connected to each other, the second covering member 444 can be covered on the second connecting column 442, the third connecting arm 443 and the seat body 441 by means of secondary injection molding or sleeving.

[0095] Further, the bottom surface of the second covering member 444 can be provided with an annular groove, the annular groove is located in the second gap 4411 and is arranged around the edge of the second gap 4411, and a plurality of reinforcing structures are arranged in the annular groove in an annular array, so as to increase the strength of the second covering member 444 through the reinforcing structures, so that the second covering member 444 can better withstand long-term or repeated loads, thereby prolonging its service life, and the second covering member 444 with higher strength can provide better support for the first power assembly 300, reduce deformation under high load conditions, thereby improving the stability of the second bearing member 400.

[0096] Further, the third connecting member 430 has two connecting portions 431. Correspondingly, the second gap 4411 has two, and each second gap 4411 is provided with the second connecting column 442, the third connecting arm 443 and the second covering member 444, and the two connecting portions 431 are connected with the two second connecting columns 442 respectively, so as to realize double damping effect and ensure the limiting stability of the second bearing member 400 to the first power assembly 300 at one end of the pump water module 330.
