[0002] A sofa is a multi-seat chair with cushions. It has a backrest with springs or thick foam and armrests on both sides. It is a type of upholstered furniture, and with the development of society, sofas have become a necessity for many families.

[0003] To meet the needs of different groups and allow for height adjustment of sofas, utility model patent number "CN210520562U" discloses an electric height-adjustable sofa. This sofa includes a base, seat cushions, and a base plate. Left uprights are fixed to both sides of the front end of the base plate, and right uprights are fixed to both sides of the rear end. A left crank is hinged to each of the left and right uprights. The top of the left crank is hinged to a left ear plate fixed to both sides of the lower left surface of the base plate, and the top of the right crank is hinged to a right ear plate fixed to both sides of the lower right surface of the base plate. The bottom of the left crank is connected to a left shaft, and the bottom of the right crank is connected to a right shaft. A left bearing is installed in the middle of the left shaft, and a first hydraulic telescopic device is installed between the left bearing and the base plate. This electric height-adjustable sofa has a simple structure, reasonable design, and high stability. By controlling the height adjustment of the sofa through electric hydraulic push rods and cranks, it achieves automatic height adjustment, effectively meeting the needs of various groups.

[0004] Although the sofas mentioned above can be adjusted in height, their complex structure presents certain manufacturing challenges. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model proposes a height-adjustable single sofa.

[0006] To achieve the above-mentioned technical effects, the present invention adopts the following solution:

[0007] A height-adjustable single sofa includes a sofa seat, armrests, and a backrest. The sofa seat includes an upper seat located at the top and a lower seat located at the bottom. The armrests and the backrest are respectively located on both sides and the back of the upper seat.

[0008] An airbag is sandwiched between the upper seat and the lower seat. The airbag is connected to an air intake pump through a first hose. The air intake pump is connected to an air intake port on the lower seat through an air intake pipe. The airbag is connected to an exhaust pump through a second hose. The exhaust pump is connected to an exhaust port on the lower seat through an exhaust pipe. A vertical guide mechanism is connected between the upper seat and the lower seat.

[0009] The lower seat is equipped with a power module, which is connected to a power cord. The armrest is equipped with an up button and a down button. The air intake pump is electrically connected to the power module through the up button, and the exhaust pump is electrically connected to the power module through the down button.

[0010] In a preferred embodiment, the guiding mechanism includes four sets of guiding components, which are arranged in a rectangular array between the upper and lower seats. Each guiding component includes a guide sleeve vertically mounted on the lower seat and a guide rod vertically mounted on the upper seat. The guide rod is inserted into the guide sleeve and slides.

[0011] In a preferred embodiment, a corrugated soft sleeve is connected between the four periphery edges of the upper seat and the four periphery edges of the lower seat.

[0012] In a preferred embodiment, both the air inlet and the air outlet are located at the lower end of the lower base.

[0013] In a preferred embodiment, a dustproof screen is provided inside the air inlet.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] This utility model has a simple structure and is easy to use. The height is adjusted by an airbag. When the up button is pressed, the air pump inflates the airbag, which inflates and lifts the upper seat. When the down button is pressed, the air pump expels air, the airbag shrinks, and the upper seat descends. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] A height-adjustable single sofa includes a sofa seat, armrests 3 and backrest 4. The sofa seat includes an upper seat 1 located above and a lower seat 2 located below. The armrests 3 and backrest 4 are respectively located on both sides and the back of the upper seat 1.

[0020] An airbag 5 is sandwiched between the upper seat 1 and the lower seat 2. The airbag 5 is connected to an air intake pump 6 through a first hose. The air intake pump 6 is connected to an air intake port 8 on the lower seat 2 through an air intake pipe. The airbag 5 is connected to an exhaust pump 7 through a second hose. The exhaust pump 7 is connected to an exhaust port on the lower seat 2 through an exhaust pipe. A vertical guide mechanism is connected between the upper seat 1 and the lower seat 2.

[0021] The lower seat 2 is equipped with a power module, which is connected to a power cord. The armrest 3 is equipped with an up button 13 and a down button 14. The air intake pump 6 is electrically connected to the power module through the up button 13, and the exhaust pump 7 is electrically connected to the power module through the down button 14.

[0022] The height is adjusted by the airbag 5. Pressing the rise button 13 inflates the airbag 5, which inflates the upper seat 1 and raises it. Pressing the fall button 14 inflates the airbag 5, which inflates the upper seat 1 and raises it. Pressing the fall button 7 inflates the airbag 5 and lowers the upper seat 1. The guide mechanism restricts the upper seat 1 to move only vertically.

[0023] In a preferred embodiment, the guiding mechanism includes four sets of guiding components, which are arranged in a rectangular array between the upper seat 1 and the lower seat 2. Each guiding component includes a guide sleeve 10 vertically mounted on the lower seat 2 and a guide rod 11 vertically mounted on the upper seat 1. The guide rod 11 is inserted into the guide sleeve 10 and slides.

[0024] In a preferred embodiment, a corrugated soft sleeve 12 connects the four perimeter edges of the upper seat 1 and the four perimeter edges of the lower seat 2. The corrugated soft sleeve 12 connects the edges of the upper seat 1 and the lower seat 2, enclosing the guide mechanism and airbag 5, thus improving the aesthetics of the single sofa and protecting the airbag 5 and the guide mechanism.

[0025] In a preferred embodiment, both the air inlet 8 and the air outlet are located at the lower end of the lower seat 2.

[0026] In a preferred embodiment, the air inlet 8 is equipped with a dust filter. Because the area under the sofa is difficult to clean, dust accumulates significantly over time. The air inlet 8, located at the bottom of the lower seat 2, easily draws in dust, which is then filtered out by the dust filter.
