Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more particularly to a vacuum cleaner. Background Technology

[0002] With the development of the pet market, pet grooming tools are becoming increasingly popular. Pet grooming tools generally fall into two categories: one type only trims the pet's fur, then the hair is manually swept into a trash can. The advantage of this type is that it doesn't produce noise and is convenient for owners to clean up. The other type has a vacuum function. This type of device can collect the trimmed hair while grooming, eliminating the need for separate cleaning. However, it produces more noise during operation, which can frighten some animals and make grooming inconvenient for owners.

[0003] Therefore, noise reduction measures are needed for vacuum cleaners to meet market demands. Summary of the Invention

[0004] To address the shortcomings of the aforementioned technologies, this invention provides a vacuum cleaner that can effectively reduce noise.

If the specific posture changes, the directional indication will also change accordingly.

[0033] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] refer to Figure 1-12 This application discloses a vacuum cleaner 100. In the figure, the larger arrow indicates the airflow direction before the motor enters, and the smaller arrow indicates the airflow direction after the motor exits. The vacuum cleaner 100 includes a base 2 and a main housing 1 disposed on the base 2. The main housing 1 defines a motor housing cavity, within which a motor 11 for generating suction airflow is disposed. The main housing 1 also defines a mounting platform for mounting a dust cup 3, which is detachably mounted to the mounting platform. The motor 11 and the dust cup 3 are arranged side-by-side. The motor 11 is vertically disposed within the motor housing cavity, and an air inlet duct 18, fluidly connecting the dust cup 3 and external accessories (hose, cleaning head, etc.), is disposed above the motor 11. Part of the air inlet duct 18 is disposed within the motor housing cavity, which can also reduce some noise. Preferably, the air inlet duct 18 can be disposed directly above the motor 11. At least a portion of the base 2 is disposed below the main housing 1. The base 2 can be integrally formed with the main shell 1, or it can be detachably and fixedly connected together; no specific limitations are made here.

[0036] refer to Figure 6-8The base 2 defines a suction pipe 28 for airflow, located upstream of the motor's air inlet 111. The base 2 also defines an air outlet channel 27 downstream of the motor's air outlet 112. The air outlet channel 27 at least partially surrounds a portion of the suction pipe 28, and a first silencer 271 is provided within the air outlet channel 27, through which airflow is discharged to the outside of the vacuum cleaner 100. Specifically, the base 2 includes an upper wall 21, a lower wall 23, an outer peripheral wall 24, and an inner peripheral wall 26, with at least a portion of the suction pipe 28 defined between the upper wall 21, lower wall 23, and inner peripheral wall 26. At least a portion of the air outlet channel 27 is defined between the upper wall 21, lower wall 23, inner peripheral wall 26, and outer peripheral wall 24. The upper wall 21, lower wall 23, outer peripheral wall 24, and inner peripheral wall 26 can be integrally formed or independently installed; this is not limited here. In the embodiment shown in the figure, the outer peripheral wall 24 and the inner peripheral wall 26 are integrally formed onto the lower wall 23, and the upper wall 21 is detachably fixed to the upper part of the lower wall 23, thus defining at least a portion of the suction pipe 28 and at least a portion of the air outlet channel 27.

[0037] refer to Figure 1-3 9. 10. The air inlet 33 of the dust cup is located on the side wall 31 of the dust cup 3, and the air outlet 34 of the dust cup is located on the bottom cover 32 of the dust cup 3. The air inlet and outlet directions of the dust cup 3 are basically perpendicular. The air inlet 33 of the dust cup is located at the top of the dust cup 3, and the air outlet 34 of the dust cup is located on the bottom cover 32. The bottom cover 32 can be opened for easy emptying of dust. Since the dust cup 3 of the pet cleaner mainly contains pet hair, very little will leak out from the air outlet. The air inlet and outlet directions of the dust cup 3 are basically perpendicular, and the air outlet is located at the bottom, which can effectively prevent hair from moving around in the dust cup 3 and can quickly collect the hair at the bottom.

[0038] The suction airflow generated by motor 11, carrying dirt, enters dust cup 3 through air inlet duct 18. The dirt is retained in dust cup 3, and the airflow flows out from dust cup outlet 34. Then, it enters motor inlet 111 through suction pipe 28 and exits from motor outlet 112. The exited airflow is discharged to the outside of vacuum cleaner 100 through exhaust duct 27. With the above structure, exhaust duct 27 is set to surround suction pipe 28, and a silencer is installed inside exhaust duct 27. The airflow is discharged after passing through the silencer. This arrangement can reduce the noise of the airflow before entering the motor and the noise of the airflow after exiting motor 11.

[0039] refer to Figure 6-8The upper wall 21 has multiple air inlets 211 arranged around the air outlet 282 of the suction pipe; the lower wall 23 has multiple air outlets 231 arranged around the air inlets 281 of the suction pipe. This arrangement allows the suction pipe 28 within the entire base 2 to be completely surrounded by the air outlet channel 27, further reducing noise. This surrounding is not limited to complete enclosure; it can also be partial enclosure or located near the openings.

[0040] To further reduce noise, in addition to noise reduction measures for the piping, noise reduction can also be applied to the motor 11, as the high-speed operation of the motor 11 also generates considerable noise. (Reference) Figure 2-4 11 and 12, the motor housing cavity is provided with an inner motor cover 12 located around the motor 11 and an outer motor cover 14 located around the inner motor cover 12. A second silencer 121 is provided between the motor 11 and the inner motor cover 12, and a third silencer 141 is provided between the inner motor cover 12 and the outer motor cover 14. The airflow discharged from the motor 11 first passes through the second silencer 121, then passes through multiple through holes opened on the inner motor cover 12 and enters the space defined between the outer motor cover 14 and the inner motor cover 12. In this space, the third silencer 141 is provided. After the airflow passes through the third silencer 141, it enters multiple air inlets 211 on the upper wall 21, then passes through the air outlet 27, and is discharged from the air outlet 231 on the lower wall 23 of the vacuum cleaner 100. Multiple through holes on the inner cover 12 and multiple air inlets 211 on the upper wall 21 are respectively located on both sides of the motor 11. That is, the multiple through holes on the inner cover 12 are located on the right side of the motor 11 axis, and the multiple air inlets 211 on the upper wall 21 are located on the left side of the motor 11 axis. This increases the airflow distance, allowing the airflow to fully contact the noise-reducing component, which can be made of filter cotton or other sound-absorbing materials. This effectively reduces noise.

[0041] refer to Figure 11 and 12To further reduce the noise generated by the vibration of the motor 11, the mounting structure of the motor 11 was also improved. A damping component was used to create a flexible connection between the motor 11 and the inner motor housing 12. Specifically, the outer motor housing 14 is detachably fixed to the base 2. The upper end of the inner motor housing 12 is detachably mounted inside the outer motor housing 14 via a damping pad 13. A through hole is provided at the top of the inner motor housing 12, through which a limiting member 17 passes. The lower end of the limiting member 17 is mounted on the motor 11, and the upper end of the motor is limited by the limiting member against the inner housing. The limiting member can be made of damping materials such as rubber, which can effectively reduce the transmission of vibrations generated by the motor to the inner motor housing. The other end of the limiting member 17 extends into the limiting groove defined by the outer motor housing 14. The peripheral wall of the limiting member 17 contacts the limiting groove, preventing the limiting member 17 from swaying left and right. The top of the limiting member 17 does not contact the limiting groove, ensuring that the motor 11 can move a certain distance in the vertical direction, thus achieving a damping effect. The lower end of the motor inner cover 12 is connected to the base 2 via a shock-absorbing support. The air inlet 111 of the motor and the air outlet 282 of the suction pipe are in fluid communication via a shock-absorbing support 16.

[0042] The shock-absorbing support 16 includes a connecting end 161 for fluidly connecting the air inlet 111 of the motor and the air outlet 282 of the suction pipe, the connecting end 161 penetrating the motor inner cover 12. The motor inner cover 12 includes an upper inner cover 122 and a lower inner cover 123. The shock-absorbing support 16 also includes a mounting end 162, which is installed at the joint between the upper inner cover 122 and the lower inner cover 123. The connecting end 161 can be a corrugated structure, which is snapped onto the opening of the lower inner cover 123. Of course, the connecting end 161 can also be other shapes. The mounting end 162 has a ring-shaped structure and is installed between the upper inner cover 122 and the lower inner cover 123, while also achieving a seal between the upper inner cover 122 and the lower inner cover 123. A receiving cavity is defined between the mounting end 162 and the connecting end 161, which can accommodate part of the motor 11. A shock-absorbing support component 16 is used here to simultaneously reduce vibration between the motor 11 and the motor inner cover 12, and between the motor inner cover 12 and the base 2, which can effectively reduce costs and achieve noise reduction.

[0043] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
