Description

Technical Field

[0001] This utility model relates to the field of washing machine shock absorber technology, specifically a washing machine shock absorber cylinder structure. Background Technology

[0002] Washing machine shock absorbers are used to reduce the vibration and noise generated by the operation of the washing machine drum. They ensure stable operation and extend the life of the washing machine, making them an indispensable part of the washing machine. However, existing washing machine shock absorbers often experience damping failure during long-term use. Furthermore, most shock absorbers require removal from the washing machine for maintenance operations such as adding damping oil, which is cumbersome and inconvenient for later maintenance and normal use, thus having certain shortcomings. Utility Model Content

The top of the column is slidably disposed in the cylinder. The spring is installed in the cylinder, with the top of the spring abutting against the top of the cylinder and the bottom of the spring abutting against the top of the column. A rubber pad is fixedly installed at the bottom of the column. A threaded mounting post is fixedly connected at the center of the top of the cylinder.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a washing machine shock absorber drum structure, mainly composed of a damping cylinder 1, a damping oil container 3, and a pressing airbag 4. The damping cylinder 1 is formed by a first damping cylinder 101, a container-mounted damping cylinder 102, and a second damping cylinder 103 connected by threads. The connection between the container-mounted damping cylinder 102 and the first damping cylinder 101 and the second damping cylinder 103 is threaded. The inner wall of the top end of the first damping cylinder 101 and the inner wall of the bottom end of the second damping cylinder 103 are provided with internal threads. The outer walls of the top and bottom ends of the container-mounted damping cylinder 102 are provided with external threads. This threaded connection method makes the connection between the components tight and firm, and facilitates disassembly and maintenance in the future. When it is necessary to repair or replace the damping cylinder 1, the parts can be directly unscrewed for operation, which improves the maintainability of the device.

[0019] Furthermore, the damping oil container 3 is an annular box, fixedly installed outside the damping cylinder 102. Liquid holes 305 are provided on the contact surfaces between the damping oil container 3 and the damping cylinder 102, as well as on the damping cylinder 102 itself. The height of the liquid holes 305 is selected according to actual conditions, allowing the damping oil to flow smoothly into the damping cylinder 1 through the liquid holes 305. An oil filling nozzle 301 is provided on the top of the damping oil container 3. A cap is threaded onto the top of the oil filling nozzle 301. When adding damping oil to the damping oil container 3, simply unscrew the cap and inject the damping oil through the oil filling nozzle 301 using a syringe or other tools. This eliminates the need to remove the entire device from the washing machine, greatly simplifying the adding of damping oil and facilitating subsequent maintenance and normal use of the device.

[0020] Furthermore, the pressure airbag 4 is installed on the outside of the damping oil container 3 in a ring shape. It contains a compression spring and a second one-way valve 304 at the bottom. When the pressure airbag 4 is squeezed, the internal gas is forced into the damping oil container 3 under the action of the compression spring. At this time, the second one-way valve 304 prevents gas from flowing out, allowing gas to smoothly enter the damping oil container 3. When the pressure airbag 4 returns to its original position, the second one-way valve 304 can draw external gas into the pressure airbag 4. Inside, the normal working cycle of the airbag 4 is ensured. At the same time, the top of the damping oil container 3 is provided with a first one-way valve 302. The bottom end of the first one-way valve 302 extends into the interior of the damping oil container 3. The air outlet 303 is connected to one end of the first one-way valve 302 through an air pipe. When the airbag 4 is pressed to squeeze the gas, the gas enters the first one-way valve 302 through the air pipe and the air outlet 303, thereby increasing the gas in the damping oil container 3 and causing the damping oil to flow out from the liquid hole 305.

[0021] In practical use, the column 2 is installed inside the damping cylinder 1. When the movement of the column 2 inside the damping cylinder 1 causes damping failure, the operator holds and presses the air bladder 4 repeatedly to allow gas to enter the damping oil container 3. As the gas in the damping oil container 3 increases, the internal pressure increases, thereby forcing the damping oil out from the liquid hole 305. When the column 2 passes by, the damping oil adheres to the surface of the column 2, effectively restoring the damping capacity of the shock absorber and ensuring the shock absorption effect during normal operation of the washing machine. When the damping oil level exceeds the liquid hole 305, it will flow out little by little. Damping oil can be added to the column 2 without manual squeezing, reducing the maintenance frequency of the washing machine shock absorber.

[0022] The working process of this utility model is as follows:

[0023] like Figure 1 - Figure 4 As shown, during use, damping oil can be injected into the damping oil container 3 through the filler nozzle 301 using a syringe. When the movement of the column 2 within the damping cylinder 1 causes damping failure, the operator holds and presses the air bladder 4. When the air bladder 4 is squeezed, the gas inside the air bladder 4 is forced into the damping oil container 3, increasing the gas level within the container. This causes the damping oil in the container 3 to flow out through the liquid hole 305. When the column 2 passes through the damping oil, the damping oil adheres to the surface of the column 2, thereby restoring the damping capacity of the shock absorber. This cylinder structure has the advantages of convenient damping oil addition and maintenance without disassembling the device.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
