Description

Technical Field

[0001] This utility model relates to the field of treatment chair technology, and more specifically to a multifunctional dental treatment chair. Background Technology

[0002] With the continuous development of oral medicine, oral treatment technology is also constantly improving. As an important tool in the treatment process, the dental chair, through its ergonomic design, can ensure that patients maintain a comfortable posture during treatment and reduce discomfort caused by sitting or lying down for a long time.

[0003] The existing dental chairs have significant shortcomings in heat dissipation performance in the seat area. When patients need to sit on the chair for a long time during dental treatment, the poor heat dissipation of the seat makes it difficult for heat to dissipate effectively, which can easily lead to sweating and reduced comfort.

[0004] Therefore, in order to solve the above problems, this application provides a multifunctional dental treatment chair. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multifunctional dental chair to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a multifunctional dental treatment chair, including a chair body assembly and a heat dissipation assembly installed on the chair body assembly, an air supply assembly is provided below the chair body assembly, a sliding assembly is fixedly installed between the chair body assembly and the air supply assembly, and a limiting assembly is installed at the bottom of the chair body assembly;

[0007] Preferably, the chair body assembly includes a main chair body, support legs, heat dissipation grooves, air inlets, air outlets, and reinforcing blocks. A pair of support legs are fixedly installed at the bottom of the main chair body. The seat portion of the main chair body has heat dissipation grooves. An air inlet is located at the center of the heat dissipation grooves on the main chair body. Air outlets are located on both sides of the seat portion of the main chair body. The reinforcing blocks are disposed within the air outlets and fixedly connected to the main chair body. At this time, the air supply assembly brings air into the heat dissipation grooves in the main chair body. Part of the airflow dissipates heat from the heat dissipation assembly, while the rest of the airflow is discharged through the air outlets on both sides of the main chair body. The reinforcing blocks reinforce the main chair body portion with the air outlets.

[0008] Preferably, the heat dissipation assembly includes an alloy plate, first mounting screws, mesh holes, and a heat dissipation pad. The alloy plate is snapped onto the top of the main chair seat. The alloy plate has first mounting screws at its four corners, with the threaded ends of the first mounting screws passing through the alloy plate and snapping onto the main chair seat. The alloy plate has evenly distributed mesh holes in its center. The heat dissipation pad is attached to the alloy plate, allowing airflow to dissipate heat through the mesh holes. During subsequent disassembly and maintenance, the heat dissipation pad can be torn off, and the first mounting screws can be unscrewed outwards to remove the alloy plate from the snap-fit ​​point for maintenance of the chair seat assembly.

[0009] Preferably, the air supply assembly includes an air supply shell, an air supply hole, a motor, a first gear, a second gear, a meshing toothed belt, a rotating rod, air supply blades, and a limiting frame. The air supply shell is located directly below the main chair body, and the air supply shell has an air supply hole that corresponds to the air inlet hole. The motor is fixedly installed on the bottom left side of the air supply shell. The motor drive shaft passes through the air supply shell and is fixedly sleeved on the first gear. The second gear is fixedly sleeved on the rotating rod. The meshing toothed belt meshes and wraps between the first gear and the second gear. The limiting frames are fixedly installed in pairs on the inner wall of the lower side tube of the air supply shell and are rotatably sleeved on the rotating rod. The air supply blades are located between the two limiting frames and are fixedly sleeved on the rotating rod. At this time, the motor drive shaft drives the first gear to rotate, which in turn drives the second gear through the meshing toothed belt, causing the rotating rod fixedly sleeved on it to rotate, thereby driving the air supply blades to rotate.

[0010] Preferably, the sliding assembly includes a slide rail, a slide groove, a slider, and a second mounting screw. The slider is fixedly installed on both sides of the air supply housing. The slide rails are arranged in pairs on both sides of the air supply assembly. The slide rails have slide grooves. The slider is slidably connected between the main chair seat base plate and the slide rail through the slide grooves. When the air supply assembly is pulled outward, the air supply assembly drives the slider to slide outward along the slide rail.

[0011] Preferably, the limiting component includes a limiting sleeve, a limiting block, an angled protrusion, and a spring. The limiting components are arranged in pairs on the left side of the air supply component. The limiting sleeve is fixedly installed at the bottom of the main chair seat. The limiting block is vertically slidably engaged in the inner cavity of the limiting sleeve. An angled protrusion is provided on the lower side of the limiting block. The springs are arranged in pairs in the inner cavity of the limiting sleeve. When the air supply component is slidably installed and passes through the limiting component, due to the angled design of the angled protrusion, the limiting block slides upward along the inner cavity of the limiting sleeve until the air supply component abuts against the second mounting screw. Then, the limiting block slides downward under the action of the spring to limit the air supply component.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] The air supply component, designed in conjunction with the chair body component, can effectively dissipate heat from the heat dissipation component, preventing patients from sitting in a poorly ventilated position for extended periods, which can lead to high local temperatures, sweating, and reduced comfort. At the same time, the design of the sliding and limiting components, along with the detachable design of the heat dissipation component, makes subsequent maintenance and cleaning more convenient and quick.

A pair of support legs 102 are fixedly installed at the bottom of the main chair body 101. The seat part of the main chair body 101 has a heat dissipation groove 103. An air inlet 104 is opened at the center of the heat dissipation groove 103 on the main chair body 101. Air outlet square holes 105 are opened on both sides of the seat of the main chair body 101. The reinforcing block 106 is placed in the air outlet square hole 105 and fixedly connected to the main chair body 101. At this time, the air supply assembly 3 brings air into the heat dissipation groove 103 opened in the main chair body 101. Part of the airflow dissipates heat from the heat dissipation assembly 2, and the rest of the airflow is discharged through the air outlet square holes 105 opened on both sides of the main chair body 101. The reinforcing block 106 reinforces the part of the main chair body 101 with the air outlet square hole 105.

[0023] Reference Figure 2 The heat dissipation component 2 includes an alloy plate 201, first mounting screws 202, mesh 203, and heat dissipation pads 204. The alloy plate 201 is snapped onto the top of the main chair body 101. The four corners of the alloy plate 201 are provided with first mounting screws 202. The threaded ends of the first mounting screws 202 pass through the alloy plate 201 and are threaded onto the main chair body 101. The center of the alloy plate 201 has evenly distributed mesh 203. The heat dissipation pads 204 are attached to the alloy plate 201. At this time, airflow can pass through the mesh 203 to dissipate heat from the heat dissipation pads 204. During subsequent disassembly and maintenance, the heat dissipation pads 204 can be torn off, and the first mounting screws 202 can be unscrewed outwards to remove the alloy plate 201 from the snap-fit ​​point for maintenance of the chair body component 1.

[0024] Reference Figure 2 and Figure 3The air supply assembly 3 includes an air supply housing 301, an air supply hole 302, a motor 303, a first gear 304, a second gear 305, a meshing toothed belt 306, a rotating rod 307, an air supply blade 308, and a limiting bracket 309. The air supply housing 301 is located directly below the main chair body 101. The air supply hole 302 is provided on the air supply housing 301, corresponding to the air inlet hole 104. The motor 303 is fixedly installed on the bottom left side of the air supply housing 301. The drive shaft of the motor 303 passes through the air supply housing 301 and is fixedly sleeved onto the first gear 304. The second gear... 305 is fixedly sleeved with the rotating rod 307, and the meshing toothed belt 306 is meshed and wound between the first gear 304 and the second gear 305. The limiting frame 309 is fixedly installed in pairs on the inner wall of the lower side pipe of the air supply shell 301 and is rotatably sleeved with the rotating rod 307. The air supply blade 308 is set between the two limiting frames 309 and is fixedly sleeved with the rotating rod 307. At this time, the transmission shaft of the motor 303 drives the first gear 304 to rotate, and then drives the second gear 305 through the meshing toothed belt 306, so that the rotating rod 307 fixedly sleeved with it rotates, and then drives the air supply blade 308 to rotate.

[0025] Reference Figure 1 and Figure 4 The sliding component 4 includes a slide rail 401, a slide groove 402, a slider 403, and a second mounting screw 404. The slider 403 is fixedly installed on both sides of the air supply housing 301. The slide rails 401 are arranged in pairs on both sides of the air supply component 3. The slide rails 401 are provided with slide grooves 402. The slider 403 is slidably connected between the seat base plate of the main chair body 101 and the slide rails 401 through the slide grooves 402. When the air supply component 3 is pulled outward, the air supply component 3 drives the slider 403 to slide outward along the slide rails 401.

[0026] Reference Figure 1 and Figure 5 The limiting component 5 includes a limiting sleeve 501, a limiting block 502, an angled protrusion 503, and a spring 504. The limiting components 5 are arranged in pairs on the left side of the air supply component 3. The limiting sleeve 501 is fixedly installed at the bottom of the seat of the main chair body 101. The limiting block 502 is vertically slidably engaged in the inner cavity of the limiting sleeve 501. An angled protrusion 503 is provided on the lower side of the limiting block 502. The springs 504 are arranged in pairs in the inner cavity of the limiting sleeve 501. When the air supply component 3 is slidably installed and passes through the limiting component 5, due to the angled design of the angled protrusion 503, the limiting block 502 slides upward along the inner cavity of the limiting sleeve 501 until the air supply component 3 abuts against the second mounting screw 404. Then, the limiting block 502 slides downward under the action of the spring 504 to limit the air supply component 3.

[0027] The working principle of this utility model is as follows: When using this device, the patient sits on the main chair body 101. The drive shaft of the motor 303 drives the first gear 304 to rotate, which in turn drives the second gear 305 through the meshing toothed belt 306, causing the rotating rod 307, which is fixedly sleeved with it, to rotate. This, in turn, drives the air supply blade 308 to rotate, bringing air into the heat dissipation groove 103 opened in the main chair body 101. Some of the airflow dissipates heat on the heat dissipation pad 204 through the mesh 203, while the rest of the airflow is discharged through the air outlet square holes 105 opened on both sides of the main chair body 101. The reinforcing block 106 reinforces the part of the main chair body 101 with the air outlet square holes 105. When dust accumulates inside the main chair body 101 or when the air supply component 3 needs maintenance, the heat dissipation pad 204 is torn open and rotated outward. Remove the first mounting screw 202, take the alloy plate 201 out of the snap-fit, press the angled protrusion 503 further and squeeze the spring 504. At this time, pull out the air supply component 3. The air supply component 3 drives the slider 403 to slide out along the slide rail 401. At this time, clean the heat dissipation groove 103. After replacing or maintaining the air supply component 3, re-snap the air supply component 3 between the slide rail 401 and the main chair body 101 through the slider 403. Push the air supply component 3 inward. When passing the limiting component 5, due to the angled design of the angled protrusion 503, the limiting block 502 slides upward along the inner cavity of the limiting sleeve 501 until the air supply component 3 abuts the second mounting screw 404. Then, the limiting block 502 slides downward under the action of the spring 504 to limit the air supply component 3.
