Description

Technical Field

[0001] The utility model belongs to the technical field of oral treatment chairs and relates to an oral treatment chair with ventilation and heating. Background Art

[0002] As people's living standards and oral health awareness improve, the frequency of people receiving oral treatment is gradually increasing. The dental treatment chair is an essential medical equipment for dentists. It allows dentists to diagnose and treat patients and provides a comfortable medical environment for oral patients. During the oral treatment process, the patient lies on the dental chair and the doctor treats the patient.

[0003] A comprehensive oral treatment chair disclosed in Chinese patent CN211461044U includes: a base; a seat cushion arranged on the base; a backrest, the lower part of which is connected to the seat cushion; a support part located above the seat cushion and arranged close to the backrest; a lifting part for driving the support part to rise and fall, so as to facilitate supporting the patient's waist, provide high comfort, and facilitate the doctor's oral treatment.

[0004] When the dental treatment chair is in use, the position of the support part is adjusted by rotating the screw rod so that the support part is close to the patient's waist to improve comfort. Since the support part can only be adjusted up and down, when the backrest is rotated to a certain angle, the distance between the backrest and the support part becomes farther, which affects the patient's comfort. Moreover, when the patient's waist is against the support part, the patient should try to remain still during dental treatment to avoid affecting the doctor's operation. The patient's waist has to be close to the support part for a long time, which is particularly prone to stuffiness in summer, causing discomfort to the patient.

[0005] In order to solve the above problems, the utility model provides a dental treatment chair with ventilation and heating. Utility Model Content

[0022] Two slide plates are fixedly connected to one side of the pedal 3; two rectangular slide grooves are provided on the side wall of the support seat 1; the two slide plates are correspondingly installed in the rectangular slide grooves for limited sliding; an anti-skid pad is fixedly installed on the upper end surface of the pedal 3 to prevent the patient's feet from slipping on the pedal 3.

[0023] A fixing frame 4 is fixedly connected to the side of the support seat 1 away from the pedal 3; the fixing frame 4 is tilted; a headrest 5 is fixedly installed on the side of the fixing frame 4 away from the support seat 1; a plurality of rubber cylinders 6 are evenly fixedly installed on the inner wall of the fixing frame 4; the upper side of the outer wall of the rubber cylinder 6 is located outside the fixing frame 4. There are intervals between the plurality of rubber cylinders 6 to increase air permeability.

[0024] Slide grooves 7 are provided on both sides of the upper end surface of the fixing frame 4; a U-shaped plate 8 is installed inside the slide groove 7 through a clamping structure; and electric lifting rods 9 are fixedly installed on both sides of the upper end surface of the U-shaped plate 8.

[0025] The clamping structure includes a limit rod 12; a plurality of limit rods 12 are arranged and evenly distributed inside the two slide grooves 7; the limit rod 12 is slidably installed on the inner wall of the slide groove 7; one end of the limit rod 12 extends out of the outside of the fixing frame 4; a toggle block 13 is fixedly connected to the end of the limit rod 12 located outside the fixing frame 4; a spring 14 is fixedly connected between the toggle block 13 and the outer wall of the fixing frame 4; the spring 14 is sleeved on the outside of the limit rod 12; the end of the limit rod 12 located inside the slide groove 7 is arranged as an inclined surface; a limit groove 15 is provided on the U-shaped plate 8 at a position corresponding to the limit rod 12; the limit groove 15 is plugged into and matched with the inclined surface end of the limit rod 12.

[0026] A lumbar pillow body 10 is fixedly mounted on the telescopic end of the electric lifting rod 9; rectangular ventilation holes 11 are evenly opened on the upper end surface of the lumbar pillow body 10; and a blowing assembly is arranged on the lumbar pillow body 10.

[0027] The blowing assembly includes three fan housings 16; the three fan housings 16 are all fixedly installed on the side walls of the lumbar pillow body 10; the fan housings 16 are all connected to the interior of the lumbar pillow body 10; air inlet holes are opened on the outside of the fan housings 16; fans 17 are fixedly installed inside the fan housings 16; a heating wire 18 is fixedly installed on one end of the inner wall of the fan housing 16 close to the lumbar pillow body 10.

[0028] It should be noted that the fan 17 and the heating wire 18 are both electrically connected to the external power source via a connecting wire, and the length of the connecting wire meets the movement requirements of the lumbar pillow body 10.

[0029] Furthermore, three air outlet holes 19 are provided on a side of the lumbar pillow body 10 facing away from the fan housing 16 ; the three air outlet holes 19 correspond to the three fan housings 16 one by one; and partitions are fixedly installed inside the air outlet holes 19 .

[0030] Working principle:

[0031] When in use, the limiting rod 12 is driven to disengage from the limiting groove 15 by pulling the corresponding toggle block 13, thereby releasing the limiting of the U-shaped plate 8, moving the U-shaped plate 8, and making the U-shaped plate 8 slide inside the slide groove 7. The movement of the U-shaped plate 8 drives the lumbar pillow body 10 to move synchronously. Since one end of the limiting rod 12 located inside the slide groove 7 is set as an inclined surface, during the movement of the U-shaped plate 8, the U-shaped plate 8 pushes the limiting rod 12 to move outward; at the same time, the spring 14 is extended; when the limiting groove 15 on the U-shaped plate 8 moves to the position corresponding to the limiting rod 12, the spring 14 contracts and drives the limiting rod 12 to be inserted into the limiting groove 15; thereby completing the limiting of the lumbar pillow body 10 and moving the lumbar pillow body 10 to a position adapted to the patient's waist. The electric lifting rod 9 can be started, and the telescopic end of the electric lifting rod 9 drives the lumbar pillow body 10 to move, thereby adjusting the protrusion of the lumbar pillow body 10, so that the patient can be more comfortable when leaning.

[0032] In order to prevent the patient from getting hot and stuffy when leaning on the lumbar pillow body 10 for a long time, the fan 17 is started, and the wind blown by the fan 17 is blown out through the air outlet 19 and the rectangular ventilation hole 11, which speeds up the air flow at the patient's waist, thereby avoiding the hot and stuffy situation and improving the comfort. When the patient's waist needs to be heated, the heating wire 18 can be energized, and the heating wire 18 emits heat after being energized; the fan 17 blows the wind from the outside of the heating wire 18 to form hot wind, which blows on the patient's waist through the rectangular ventilation hole 11, heating the patient's waist, improving the local blood circulation of the lumbar spine, and helping to relax the muscles.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
