Description

Technical Field

[0001] This invention relates to the field of cleaning appliance technology, and in particular to a vacuum cleaner main unit with a partially assembled damping and shock-absorbing structure. Background Technology

[0002] Vacuum cleaners are common household or commercial cleaning devices that clean spaces and improve the living environment by sucking up dust and other dirt from surfaces. A typical vacuum cleaner includes a main unit, an airflow generator, a cyclone separator, and a dust cup. The airflow generator draws dust and air from the outside into the main unit, while the cyclone separator separates the dust from the air. The separated dust falls into the dust cup, and the separated air exits from the main unit.

[0003] With the development of society and the economy and the improvement of living standards, people's requirements for their home environment are also increasing. They not only demand that their homes be aesthetically pleasing and comfortable, but more importantly, that they maintain cleanliness and hygiene. Therefore, the demand for vacuum cleaners has been increasing year by year, making them an indispensable household appliance for many families. Because vacuum cleaners need to clean a large area, they need to be moved frequently. During this movement, vacuum cleaners often collide with walls or surrounding furniture, which shortens their lifespan. Summary of the Invention

[0004] The present invention provides a vacuum cleaner main unit with a partially assembled damping and shock absorption structure. Through the damping and shock absorption components, the vacuum cleaner can be buffered after being hit, thus avoiding damage to the vacuum cleaner and improving its service life.

[0005] The purpose is to provide a vacuum cleaner main unit with a partially assembled damping and shock absorption structure to solve the problem that the handle of the existing vacuum cleaner is difficult to pick up and is inconvenient to use.

[0006] To achieve the above objectives, the present invention provides a vacuum cleaner main unit with a partially assembled damping and shock absorption structure, comprising: a motor assembly, a dust cup, and a HEPA filter assembly. The dust cup is provided with an air inlet and a cyclone cone is provided inside the dust cup. The HEPA filter assembly is disposed at one end of the dust cup and includes a HEPA filter frame and a first HEPA filter. The HEPA filter frame is installed at one end of the cyclone cone, the first HEPA filter is installed on the HEPA filter frame, the motor assembly is disposed at one end of the first HEPA filter, and the motor assembly is connected to the dust cup.

[0007] The motor assembly includes a motor, a motor cover, and a motor end cap. One end of the motor end cap is connected to the dust cup, and the other end of the motor end cap is connected to the motor cover. The motor is built into the motor cover. The motor cover has several through holes, which are arranged at intervals along the circumference of the motor cover. Damping and vibration reduction components are installed in the through holes.

[0008] As a further description of the above technical solution:

[0009] The damping and shock absorption component includes a rubber damping block and a damping element. The flexible connecting block is connected to the motor cover, and the damping element is connected to the rubber damping block.

[0010] As a further description of the above technical solution:

[0011] The rubber damping block is provided with at least one mounting cavity, and the damping element is disposed in the mounting cavity.

[0012] As a further description of the above technical solution:

[0013] The damping element is a damper.

[0014] As a further description of the above technical solution:

[0015] The damping element includes a shock absorber block, a left shock absorber spring, a right shock absorber spring, a left connecting rod, and a right connecting rod. The two ends of the shock absorber block are respectively connected to one end of the left shock absorber spring and one end of the right shock absorber spring. One end of the left connecting rod is connected to the left shock absorber spring, and one end of the right connecting rod is connected to the left and right shock absorber springs. The left connecting rod and the right connecting rod extend out of the mounting cavity and are connected to the motor cover.

[0016] As a further description of the above technical solution:

[0017] The mounting cavity is filled with refrigeration oil.

[0018] As a further description of the above technical solution:

[0019] The rubber shock absorber block is provided with a left connecting rod and a through hole from which the right connecting rod extends, and a sealing ring is provided at the through hole.

[0020] As a further description of the above technical solution:

[0021] The motor cover is provided with several air outlets, and a second HEPA filter is provided at the air outlet.

[0022] As a further description of the above technical solution:

[0023] The outer side of the second HEPA filter is provided with a HEPA cover, which is connected to the motor cover.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In this invention, by opening through holes in the motor cover, the vibration characteristics of the structure can be affected by changing the mass distribution and introducing stress concentration effects. Installing damping and shock-absorbing components at the through holes is equivalent to creating a flexible region with low stiffness in a local area. When vibration or impact loads are transmitted, these damping and shock-absorbing components undergo elastic deformation, dissipating some energy and achieving the purpose of shock absorption. They can also change the natural frequency of the structure, avoid resonance with external excitation, and achieve the purpose of vibration isolation.

[0026] 2. In this invention, when the motor housing is impacted at both ends, the force is transmitted to the rubber damping block, causing the rubber damping block to deform. This allows the damping element to absorb energy and achieve the purpose of vibration reduction. Specifically, the damping element consists of a damping block, a left damping spring, a right damping spring, a left connecting rod, a right connecting rod, and refrigeration oil. The left and right damping springs are located at both ends of the damping block, which can balance the vibration. The mounting cavity absorbs vibration energy through the damping effect of the left and right damping springs, combined with the buffering effect of the damping block and the refrigeration oil, thereby achieving the purpose of reducing vibration.

[0027] 3. In this invention, by installing a first HEPA filter and a second HEPA filter at both ends of the motor respectively, the filtration effect can be improved, the amount of dust entering the motor can be reduced, and the service life of the motor can be increased.

The rubber damping block utilizes the high elasticity and viscoelasticity of rubber to absorb and disperse vibration energy, thereby reducing vibration. At the same time, the damping element can absorb energy again, thus improving the shock absorption effect.

[0045] The rubber damping block 71 is provided with at least one mounting cavity 8, and the damping element 72 is disposed in the mounting cavity 8.

[0046] Example 2:
