Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of vacuum cleaner components, and more specifically, it relates to an automatic compensation structure for the contact pressure between the vacuum cleaner head and the ground. Background Technology
[0002] The compensation structure is used to reduce the resistance of the vacuum cleaner brush head movement. During general cleaning, when using a conventional vacuum cleaner, the suction port is surrounded by a brush. If too much force is applied, the brush will bend. Uneven force will cause some brushes to not be in contact with the ground, affecting cleaning.
[0003] Based on the above, the vacuum cleaner heads currently in use use a flexible rotating connection structure to compensate for this, which makes it inconvenient to adjust the contact pressure of the brush according to the type of debris, and lacks a pressure limiting adjustment function. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides an automatic compensation structure for the contact pressure between a vacuum cleaner head and the ground. This solves the problem mentioned in the background art that existing vacuum cleaner heads use a flexible rotating connection structure for compensation, which makes it inconvenient to adjust the contact pressure of the brush according to the type of debris and lacks a pressure limiting adjustment function.
[0005] The purpose and function of this utility model's automatic pressure compensation structure for vacuum cleaner heads in contact with the ground are achieved through the following specific technical means: An automatic pressure compensation structure for vacuum cleaner head contacting the ground includes a long, narrow vacuum head. Brushes are fixedly installed at the bottom front end and both sides of the long, narrow vacuum head. A sponge strip is fixedly installed at the bottom rear side of the long, narrow vacuum head, with both ends of the sponge strip attached to the brushes. A hinge seat is fixedly installed at the top of the long, narrow vacuum head, and a suction tube is hinged to the hinge seat. Electric cylinders are fixedly installed at the upper center of both sides of the long, narrow vacuum head. A support frame is fixedly installed at the extension end of the electric cylinder, and support wheels are rotatably installed on both sides of the support frame below.
[0006] Furthermore, sliding frames are fixedly installed on both sides of the elongated vacuum head, and the support frame is a corner structure that is slidably connected to the sliding frames.
[0007] Furthermore, a water pipe is integrally provided on the rear side of the vacuum pipe, and a space is left between the vacuum pipe and the water pipe for threading.
[0008] Furthermore, a water spray nozzle is fixedly installed on the rear side of the elongated vacuum head. The bottom of the water spray nozzle is sloping, and a row of nozzles is fixedly installed at the bottom of the water spray nozzle, with the bottom of the nozzles tilted forward.
[0009] Furthermore, a corrugated pipe is provided to connect the suction pipe to the top of the elongated suction head.
[0010] Furthermore, a flexible hose is provided between the bottom end of the water pipe and the rear side of the water spray outlet.
[0011] Furthermore, a telescopic piston rod is hinged between the front side of the suction pipe and the front side of the hinge seat, and a solenoid valve is fixedly connected to the tail end of the telescopic piston rod.
[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention allows for precise adjustment of the contact pressure between the brush and sponge strip and the ground, and can flexibly change the height according to the type of waste: for light and thin waste such as paper scraps and hair, it can be raised so that it does not touch the ground, and can be efficiently collected by vacuuming alone; for larger heavy objects or stains stuck to the ground, the height can be lowered to allow the brush to fully contact the ground, enhance the cleaning force, effectively avoid the problem of brush bending and deformation caused by uneven force during manual operation, and ensure the durability of the cleaning components.
[0013] Not only can it perform regular vacuuming with the suction hose, but it can also use the water spray nozzle and sponge strip to rinse the floor, allowing for seamless vacuuming and mopping without the need to change tools. At the same time, the suction head angle can be flexibly adjusted and fixed through the telescopic piston rod and solenoid valve, easily adapting to special scenarios such as under furniture, corners, and other low or narrow spaces, greatly improving the cleaning coverage and overall cleaning efficiency.
[0014] The sliding frames on both sides of the long, narrow vacuum head are slidably connected to the corner support frame, ensuring the stability of the support frame when moving up and down, and making the height adjustment process smooth and reliable. The vacuum hose is connected to the corrugated pipe at the top of the long, narrow vacuum head, and the water hose is connected to the flexible hose of the water spray nozzle, which ensures the smooth transmission of airflow and water flow without affecting the angle adjustment of the vacuum head.

Detailed Implementation
[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. Example 1
[0022] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides an automatic pressure compensation structure for the contact between a vacuum cleaner head and the ground, including a long strip-shaped vacuum head 1. Brushes 101 are fixedly installed at the bottom front end and both sides of the long strip-shaped vacuum head 1. A sponge strip 102 is fixedly installed at the bottom rear side of the long strip-shaped vacuum head 1, with both ends of the sponge strip 102 attached to the brushes 101. A hinge seat 104 is fixedly installed at the top of the long strip-shaped vacuum head 1, and a vacuum tube 3 is hinged in the hinge seat 104. Electric cylinders 2 are fixedly installed at the upper middle of both sides of the long strip-shaped vacuum head 1. A support frame 201 is fixedly installed at the telescopic end of the electric cylinder 2. Support wheels 202 are rotatably installed on both sides of the lower part of the support frame 201.
[0023] The long strip-shaped vacuum head 1 has a sliding frame 103 fixedly installed on both sides, and the support frame 201 has a corner structure and is slidably connected to the sliding frame 103.
[0024] The vacuum cleaner 3 has a water pipe 301 integrated on its rear side, and there is a space between the vacuum cleaner 3 and the water pipe 301 for threading.
[0025] Among them, a water spray row 4 is fixedly installed on the rear side of the inner side of the long strip-shaped dust suction head 1. The bottom of the water spray row 4 is a slope. A row of nozzles 401 is fixedly installed at the bottom of the water spray row 4. The bottom of the nozzles 401 is tilted forward.
[0026] A corrugated pipe is provided between the suction pipe 3 and the top of the long strip suction head 1 for connection.
[0027] A flexible hose is installed between the bottom end of water pipe 301 and the rear side of water spray outlet 4.
[0028] A telescopic piston rod 5 is hinged between the front side of the suction pipe 3 and the front side of the hinge seat 104, and a solenoid valve 501 is fixedly connected to the tail end of the telescopic piston rod 5.
[0029] The end of the suction pipe 3 is connected to the vacuum cleaner and control device. The vacuum cleaner has a water tank or detergent tank inside, and is connected to the tank through the water pipe 301. In addition, the device is equipped with support wheels 202 and support frame 201, wherein the support wheels 202 contact the ground to assist in movement, and the support frame 201 serves to maintain position. When the electric cylinder 2 is activated, the elongated vacuum head 1 can be raised as a whole, thereby adjusting the height of the brush 101 and the sponge strip 102. The specific adjustment depends on the type of waste. For light and thin debris that can be sucked up without sweeping, the brush 101 and sponge strip 102 can be raised directly so that they do not touch the ground. At this time, simply move the long strip vacuum head 1 and start the vacuuming function to extract the debris. For heavier trash or trash stuck to the ground, the brush 101 needs to be used to separate the trash from the ground first; the brush 101 and sponge strip 102 need to be lowered to make them contact the ground, and then vacuuming can be performed; if the brush 101 and sponge strip 102 are lowered further, the cleaning effect can be enhanced. Example 2
[0030] Angle adjustment function The angle of the elongated vacuum head 1 can be adjusted. When operating, open the solenoid valve 501 and directly adjust the angle of the vacuum tube 3. The telescopic piston rod 5 will automatically adapt to the extension and retraction. When a fixed angle is needed, close the solenoid valve 501, and the position of the telescopic piston rod 5 will be fixed. At this time, the telescopic piston rod 5 generates a gas spring effect, which can retract slightly. The greater the degree of retraction, the greater the counter-push force, which can provide the angle adjustment limitation effect and buffer effect for the vacuum tube 3. Example 3
[0031] Rinse function If rinsing is required, water can be introduced through pipe 301. Water will pass through the hose into spray nozzle 4 and spray out from nozzle 401. The spray nozzle 401 is located at the bottom rear side of the long strip vacuum head 1. After moving the long strip vacuum head 1, the sponge strip 102 can be used to clean the floor, achieving the effect of a mop.
[0032] The specific usage and function of this embodiment are as follows: In this utility model, the tail end of the suction pipe 3 is connected to the vacuum cleaner and the control device. A water tank or a washing liquid tank is provided in the vacuum cleaner, and the water pipe 301 is connected to the water tank or washing liquid tank of the vacuum cleaner. The support wheel 202 contacts the ground to assist in movement, the support frame 201 maintains its position, and when the electric cylinder 2 is started, it drives the long strip-shaped vacuum head 1 to rise as a whole, thereby adjusting the height of the brush 101 and the sponge strip 102; Adjust the height of the brush 101 according to the different types of trash. For example, for thin trash that can be sucked up without sweeping, you can raise the brush 101 and the sponge strip 102 so that they do not touch the ground, and then move the long strip vacuum head 1 and start the vacuuming function to pick up the trash. For heavier trash or trash stuck to the ground, brush 101 is needed to separate the trash from the ground first. Lower brush 101 and sponge strip 102 to contact the ground for vacuuming. Lowering brush 101 and sponge strip 102 further can increase the cleaning effect. The angle of the long, narrow vacuum head 1 can be adjusted. Simply open the solenoid valve 501 and then adjust the angle of the vacuum hose 3. The telescopic piston rod 5 will automatically adapt to the extension and retraction. When it needs to be fixed, close the solenoid valve 501, and the position of the telescopic piston rod 5 will be fixed. At this time, the telescopic piston rod 5 will generate a gas spring effect, which can retract slightly. However, the more it retracts, the greater the counter-force, providing an angle adjustment limitation effect and a buffer effect for the vacuum hose 3.
[0033] If rinsing is required, water can be introduced through the water inlet pipe 301, passing through the hose into the water spray outlet 4, and sprayed out from the nozzle 401. The spray outlet of the nozzle 401 is located at the bottom rear side of the long strip vacuum head 1. Then, by moving the long strip vacuum head 1, the sponge strip 102 can be used to clean the floor, providing the effect of a mop.
