Description

TECHNICAL FIELD

[0001] The utility model relates to a cleaning device, especially a low-noise compact electric cleaning assembly and a cleaning device containing the cleaning assembly. BACKGROUND

[0002] People need to clean frequently in daily life, and electric cleaning devices such as electric cleaning brushes have become an ideal choice for modern life cleaning due to their high efficiency, convenience and multifunctional characteristics, which can be used for household cleaning, car cleaning, outdoor cleaning and appliance cleaning and other different use scenarios.

[0003] At present, in the prior art, the electric cleaning brush usually has an eccentric shaft transmission device, which transmits driving force through the eccentric shaft to realize the rotation or reciprocating motion of the brush head, thereby providing certain cleaning efficiency and effect. This technical design is widely used in many electric tools and cleaning equipment.

[0004] However, the setting mode of the eccentric shaft in the prior art is usually fixed, and the eccentric transmission member is usually arranged near the wheel hub part of the brush head. When the rotating output of the motor is transmitted to the brush head, the reciprocating rotary motion of the wheel hub is driven by the eccentric shaft to drive the brush to move. Although the cleaning effect can be achieved, this setting mode will cause a certain degree of energy loss, reducing the overall cleaning efficiency.

[0005] In addition, the movement cooperation between the eccentric shaft and the brush head in the traditional technical solution will bring about great vibration and noise, which may affect the comfort and cleaning efficiency of the user during product use. This defect is particularly significant when using the cleaning brush in a quiet environment. SUMMARY

[0006] Aspects and advantages of the utility model will be set forth in part in the following description, or can be obvious from the description, or can be learned from practice of the utility model.

[0007] To solve the above technical problems, the utility model provides a cleaning device assembly, which is suitable for assembling to an electric cleaning device, by providing an improved transmission structure, thereby reducing the energy loss in the transmission process and improving the cleaning efficiency. In addition, the cleaning device assembly of the utility model can also be provided with different swing torques, thereby providing different cleaning intensity to be suitable for different cleaning application scenarios. Further, the utility model also has a noise reduction unit to provide significant noise reduction function.

[0008] According to the first aspect of the present application, a cleaning assembly is provided, comprising: a housing defining an elongated chamber, the housing having a leading end and a trailing end; a cleaning member attached to the trailing end of the housing for performing a cleaning operation; a transmission rod located within the chamber and extending along the length direction of the chamber from a position proximate to the leading end of the housing towards the trailing end of the housing, the transmission rod being elongated and having a first end proximate to the leading end of the housing and a second end opposite to the first end, wherein the first end of the transmission rod is drivable to cause the transmission rod to perform an oscillating motion; a motion conversion member located at least partially within the chamber and proximate to the trailing end of the housing; wherein the first end of the transmission rod is drivable to cause the transmission rod to perform an oscillating motion, and wherein the motion conversion member is engaged with the second end of the transmission rod and the cleaning member respectively, so as to convert the oscillating motion of the transmission rod and transmit it to the cleaning member to perform the cleaning operation.

[0010] Preferably, the cleaning assembly further comprises a transmission rod sleeve, which is embedded with the inner wall of the housing, and the transmission rod is sleeved within the transmission rod sleeve, so that the transmission rod is drivable to perform an oscillating motion relative to the axis between the embedded parts.

[0011] Preferably, the transmission rod sleeve is composed of a cylindrical sleeve and an extension column extending from the cylindrical sleeve, the cylindrical sleeve being configured to pass through and engage with the transmission rod, the extension column extending upwardly from the cylindrical sleeve to form an upper end portion and extending downwardly from the cylindrical sleeve to form a lower end portion, the upper end portion and the lower end portion being embedded in corresponding limiting holes of the housing respectively.

[0012] Preferably, the position of the extension column of the transmission rod sleeve relative to the cylindrical sleeve is variable.

[0013] Preferably, the extension column is vertically arranged at the middle of the cylindrical sleeve, or arranged at one-third position or three-quarter position or five-sixth position along the length direction of the cylindrical sleeve.

[0014] According to another embodiment of the first aspect of the present application, the cleaning assembly comprises at least one noise reduction unit, which is arranged at the joint of the second end of the transmission rod and the motion conversion member. Preferably, the noise reduction unit is made of noise reduction material containing sound-absorbing cotton, sound-absorbing board or polyurethane foam.

[0015] Preferably, the cleaning member comprises a mounting member configured to be coupled with the motion conversion member and to move under the action of the motion conversion member, and a brush head arranged on the mounting member and moving with the mounting member to perform the cleaning operation.

[0035] Reference will now be made in detail to embodiments of the present invention, one or more of which are illustrated in the figures. Reference numerals are repeatedly used in this specification and figures to indicate the same or similar features or elements of the present invention. It should be noted that the following is provided only to assist those skilled in the art in further understanding the present invention, and does not limit the present invention in any way. It should be pointed out that various modifications and alterations can be made by those skilled in the art without departing from the concept of the present invention. For example, features shown or described as part of one embodiment may be used with another embodiment to produce further embodiments. Therefore, the present invention is intended to cover such modifications and alterations that fall within the scope of the appended claims and their equivalents.

[0036] This utility model relates to a cleaning component and a cleaning device having the cleaning component, typically used for cleaning hard-to-clean areas such as crevices, corners, recesses, and cracks in vehicles, gardens, furniture, and other similar settings. For example, the cleaning device can be used to clean the corners of vehicle tires. Furthermore, the cleaning device can be used to wipe stains off surfaces such as carpets. Notably, the device can be used to clean various surfaces in commercial environments, homes, and other applications. The cleaning device can be implemented as an electric brush.

[0037] Figure 1 and 2 A cleaning assembly 100 according to one embodiment of the present invention is shown. In this embodiment, the cleaning assembly 100 may be the cleaning head of a cleaning brush. Figure 1 As shown, the cleaning head 100 has a housing 102 and a cleaning component 104. The housing has an end 106 and a beginning 108, and the cleaning component 104 is disposed at the end 106 of the housing 102. The housing 102 is formed by the mating of an upper housing 112 and a lower housing 114, which are engaged and positioned by a pin hole structure 116. A cavity 122 is formed between the upper housing 112 and the lower housing 114 to accommodate the transmission assembly 110. Simultaneously, a locking element (not shown) at the beginning of the housing securely locks the mated upper and lower housings 114, ensuring the robustness of the housing connection. This assembly method facilitates the disassembly and installation of the transmission assembly 110 within the housing 102.

[0038] Figures 3A-3B An embodiment of the transmission assembly 110 is further illustrated. For example... Figure 2 and Figures 3A-3BAs shown, the transmission assembly 110 includes a transmission rod 118, a transmission rod sleeve 120 and a motion conversion piece 124. The transmission rod 118 is located in the chamber 122 of the housing 102 and extends along the length of the housing from a position adjacent to the leading end 108 of the housing to the trailing end 106 of the housing. The transmission rod 118 is an elongated cylindrical rigid shaft and has a first end 126 and a second end 128. The first end 126 and the second end 128 are respectively formed as a ball. The transmission rod sleeve 120 has a generally cross shape and has a cylindrical sleeve 130 parallel to the axis of the transmission rod 118 and an extension column 132 at an angle (e.g. substantially perpendicular) to the axis of the cylindrical sleeve 130. The transmission rod 118 is inserted through the cylindrical sleeve 130 and is fixed together in a sleeved manner, and the two are in abutment. The upper and lower ends of the extension column 132 are respectively embedded in the limiting holes 134 of the housing 102 and are limited thereby. The limiting holes 134 are provided on the upper and lower housings and are symmetrical to each other, for receiving the extension column 132 of the transmission rod sleeve 120, and making the extension column 132 after assembly not move relative to the housing 102. The extension column 132 is provided at a position at a distance of substantially one, two or three times, or any other multiple of the distance to one end of the cylindrical sleeve 130 to the other end. When the transmission rod 118 is sleeved with the transmission rod sleeve 120, the extension column 132 is closer to the second end 128 of the transmission rod 118.

[0039] The first end 126 of the transmission rod 118 is coupled with a driving and transmission device in a cleaning device in which the cleaning head is installed, as shown. Figure 3C Under the driving action, the transmission rod 118 performs a swinging motion around the axis of the extension column 132. Compared with the prior art, the swinging provided by the elongated transmission rod 118 can transmit more kinetic energy to the cleaning piece 104 than the rotation provided by the rotating rod, so as to generate a better cleaning effect.

[0040] Figure 3C Further shown is an embodiment variation of the transmission assembly 110. As Figure 3CAs shown, the transmission assembly 110 further comprises an eccentric transmission mechanism 138. The eccentric transmission mechanism 138 is driven by the eccentric rotating structure 136. The first end of the eccentric rotating structure 136 is coupled with the output shaft of the motor and gear box of the cleaning device, and the second end is combined with the eccentric transmission mechanism 138. The eccentric transmission mechanism 138 can be an oscillating block. With the continuous rotation of the driving output shaft around the rotation axis of the driving shaft, the eccentric rotating structure 136 can rotate in a circle with the rotation of the driving output shaft. That is, when the driving shaft rotates, the second end of the eccentric rotating structure 136 starts to rotate in an expanding circle and is biased to the second side 142 of the oscillating block 138, i.e. the engaging side, so that the first side 140 of the oscillating block 138 swings out. The first end 126 of the transmission rod 118 is engaged with the first side 140 of the oscillating block 138, and the transmission rod 118 swings around the axis of the extension column 132 under the driving action of the oscillating block 138 and transmits the swinging motion to the motion conversion piece 124. The motion conversion piece 124 then converts the swinging motion into the cleaning operation of the cleaning piece 104.

[0041] That is, the first end 126 of the transmission rod 118 is engaged with the first side 140 of the oscillating block 138 to receive the swinging output of the oscillating block 138, and the other spherical end second end 128 of the transmission rod 118 is engaged with the motion conversion piece 124 at the end of the shell 106 for driving the motion conversion piece 124 to move, so as to transmit the driving of the driving end to the cleaning piece 104 and enable the cleaning piece 104 to perform the cleaning operation.

[0042] Fig. 4 to Figure 6B The motion conversion piece 124 and the cleaning piece 104 and the combined relationship thereof according to an embodiment of the present application are shown. Among them, Figures 4A-4C The motion conversion piece 124 in the combined state and the disassembled state is shown. As shown, the motion conversion piece 124 further comprises a shaft hole 140 and a rotation axis 142 and a shaft cap 144. The second end 128 of the transmission rod 118 is engaged with the recess 146 of the shaft hole 140 of the motion conversion piece 124 to transmit the swinging input received from the oscillating block 138 to the shaft hole 140. After receiving the swinging motion transmitted by the transmission rod 118, the motion conversion piece 124 converts it into a rotating motion around the rotation axis 142, so as to convert the swinging motion into the cleaning operation of the brush head.

[0043] Figures 5A-5B The cleaning piece 104 in the combined state and the disassembled state and the relative position relationship thereof with the motion conversion piece 124 are shown. As Figures 5A-5BAs shown, the cleaning component 104 further includes a mounting component 150 and a cleaning brush 152, wherein the mounting component 150 is coupled to and moves under the action of the motion converter 124, and the cleaning brush 152 is mounted on the mounting component 150 and moves with the mounting component 150 to perform cleaning operations. The cleaning brush 152 may be a rigid bristle brush, a circular sponge, or any other cleaning device used for cleaning functions.

[0044] Figures 6A-6B This is a schematic diagram showing the assembly relationship of the motion conversion member 124, the housing 102, and the cleaning member 104 according to an embodiment of the present invention. The following will be combined... Figures 4A-4C and 5A-5B Figures 6A-6B The structure and working mechanism shown will be described in further detail.

[0045] like Figures 6A-6B As shown, the rotating shaft 142 connects the shaft 140, the lower housing 114 and the mounting member 150 in sequence. The rotating shaft 142 is also inserted into the upper housing socket (not shown), thereby connecting the motion conversion member 124 and the mounting member 150 together. At the same time, it further restricts the relative movement of itself and its series structure, ensuring that the mounting member 150 is stable when moving around the rotating shaft 142.

[0046] Specifically, the rotating shaft 142 passes sequentially through the central hole 148 of the shaft socket 140, the opening 162 of the lower housing 114, and the central hole 160 of the mounting member 150, and connects them together in sequence. The mounting member 150 has symmetrically shaped protrusions 154, and the lower housing 114 has an opening 162 that matches the shape of the protrusions; the shaft socket 140 has symmetrical notches 156 that match the shape of the protrusions. During assembly, the protrusions 154 of the mounting member 150 are inserted into the opening 162, and after insertion, the mounting member 150 is rotated so that the protrusions 154 and the opening 162 are approximately perpendicularly misaligned, thus ensuring that the mounting member 150 will not detach from the shaft socket 140 during operation. During assembly, the notch 156 seamlessly engages with the protrusion of the mounting member 150 that is matched and installed into the opening 162. Under the limiting action of the rotating shaft 142, the shaft socket 140 drives the mounting member 150 to reciprocate and rotate together.

[0047] The shaft socket 140 converts the swing motion transmitted by the transmission rod 118 into the rotary motion of the motion conversion member 124 around the rotation shaft 142. The mounting member 150 is driven to rotate by the shaft socket 140 through the clamping structure. Since the swing motion transmitted by the oscillating block 138 to the transmission rod 118 is reciprocating, the rotary motion of the mounting member 150 driven by the shaft socket 140 is also reciprocating, so that the mounting member 150 has good cleaning ability. In addition, the mounting member 150 can also be vibrated under the driving of the shaft socket 140 for different needs.

[0048] Figures 7A-7C Further shown is the electric cleaning brush of another illustrative embodiment of the utility model, which provides a cleaning head with noise reduction function.

[0049] This embodiment contains the same structural units and mounting relationship as the electric cleaning brush in the foregoing embodiment, so the same technical features are represented by the same reference numerals in the following description. Compared with the foregoing embodiment, the transmission part of the electric cleaning brush of this embodiment is further provided with a noise reduction unit 158. Figures 1 to 6B As described above, when the eccentric transmission mechanism 138 is arranged at the proximal end close to the motor and the transmission rod is changed from the conventional rotary motion to the swing motion, the output power is improved, but at the same time, more noise is also likely to be generated, especially at the joint between the transmission rod 118 and the shaft socket 140. Therefore, in one embodiment according to the utility model, a noise reduction unit 158 is further arranged at the joint, as shown in

[0050] Figures 7A-7C

[0051] In this way, the noise and vibration generated by the motion contact between the transmission rod 118 and the shaft socket 140 of the transmission assembly 110 are reduced by the noise reduction unit 158. Preferably, the noise reduction unit 158 is arranged at the outer periphery of the notch where the motion contact is located. The noise reduction unit 158 can include at least two noise reduction members a and b. The noise reduction members can be made of noise reduction materials such as sponge, polyurethane foam plastic or natural materials. The noise reduction members a and b are arranged to fit the shaft socket 140 and are arranged on the upper and lower sides of the outer periphery of the notch.

[0052] Figure 7B A schematic view of the combination of the noise reduction unit 158 and the shaft socket 140 after installation is shown. After installation, the center line M of the two noise reduction members is perpendicular to the motion plane a of the transmission rod 118.

[0053] In addition, as another preferred embodiment of this embodiment, the noise reduction unit 158 can also include at least three noise reduction members a, b and c. The noise reduction members are arranged to fit the shaft socket 140 and are arranged on the outer periphery of the notch. ​​

[0054] Figure 7C The combination of the noise reduction unit 158 and the shaft hole 140 is shown after the installation is completed. After the installation, the center of the noise reduction unit is located in the same plane β, and the plane β is perpendicular to the movement plane α of the transmission rod 118.

[0055] Figure 8A And 8B Further shown is the combination of the noise reduction unit 158 and the shaft hole 140 after the installation is completed. After the installation, the center of the noise reduction unit is located in the same plane β, and the plane β is perpendicular to the movement plane α of the transmission rod 118. Figures 1 to 7C The electric cleaning device 200 with the cleaning head is shown. As shown, the electric cleaning device can be implemented as an electric cleaning brush, which mainly includes a driving part 210, a transmission part 220, and a cleaning part 230. Among them, the driving part 210 contains energy providing components and control components, which are used to provide driving force for the entire cleaning device and control the working mode of the electric cleaning brush. The transmission part 220 contains transmission components and motion conversion components, which are used to transmit the driving force provided by the driving part to the cleaning part. The cleaning part contains a brush and a mounting body for mounting the brush, which is used to clean the object to be cleaned under the action of the transmission part.

[0056] The driving part 210 is surrounded by a main body shell 202 and a cover 204. Among them, the main body shell has an elongated shape and defines a cavity portion. Inside the cavity, there are battery units 212, control units (PCB) 214, motors 216, gear boxes 218, and drive shafts 219 with eccentric functions, etc. The main body shell has an opening for putting in and taking out the battery. In the normal state, the opening is covered by the cover 204. The cover is detachably assembled on the side of the main body shell for accommodating the battery, which is used to close the cavity space in the main body shell.

[0057] The control unit 214 is in electrical communication with the battery unit 212 and the motor 216. The control unit 214 is responsible for controlling the operation mode and parameters of the electric cleaning brush, ensuring that the cleaning brush works in the specified mode.

[0058] The transmission part 220 includes oscillating blocks 224, transmission rods 226, and motion conversion components 228, etc. The cleaning part 230 includes mounting components 232 and brush heads 234. Its mechanical mechanism, working mechanism and principle, and materials are basically the same as those of the Figures 1 to 7C The embodiment shown is basically the same as that of the

[0059] As Figure 8A And 8BAs shown, the motor 216 is further coupled, directly or indirectly, with a drive shaft 219 with eccentric function and a gear box 218. The gear box 218 is used to provide a gear shifting function. The first end of the drive shaft 219 is coupled with the motor, so that it can continuously rotate around the rotation axis of the drive shaft during the operation of the motor. The second end of the drive shaft 219 is eccentrically mounted thereon and cooperatively engaged with the oscillating block 224, so that it can make a circular rotation with the rotation of the drive shaft 219. That is, when the drive shaft 219 spins or rotates, the second end starts to make an enlarged circular rotation and is biased to the engagement side of the oscillating block 224, so as to make the other side of the oscillating block swing. The transmission rod 118 is engaged with one side of the oscillating block 224 and swings under the action of the oscillating block 224 and transmits the swinging motion to the motion conversion piece 228. The motion conversion piece 228 converts the swinging motion into the cleaning operation of the cleaning piece 232.
