Description

Chair with detachable seat

Technical Field

The utility model belongs to the field of furniture, specific multifunctional seat that says so.

Background

The cushion of the traditional seat lacks the heat dissipation function and is not good for the health of the reproductive system of the human body. The ideal temperature for generating sperms in male testicles is about 35 ℃, because the temperature of male scrotum is adjusted through heat dissipation, the constant temperature of the testicles is kept to be favorable for the generation of the sperms, when the scrotum is supported by the cushion, the heat dissipation of the scrotum is influenced, the temperature of the scrotum is locally increased, the heat dissipation is uneven, the generation of the sperms is not favorable, and the reproductive system diseases such as infertility and the like are caused. For women, the lack of heat dissipation function of the cushion can increase the temperature of the pudendum, which results in increased secretion and gynecological diseases.

When a male sits on a soft cushion, such as a sofa, an automobile seat and the like, the buttocks can be sunk into the cushion, the scrotum is hung between two legs, the sponge is arranged below the scrotum, and the elastic sponge can extrude the scrotum to cause unsmooth scrotum venous return and varicocele. The sponge can squeeze the prostate of the male, and the prostate is subjected to repeated congestion after long-term sitting, so that the prostate disease is caused.

If the concave breathable structure is arranged on the cushion, the heat dissipation of the reproductive system of a human body is facilitated, and the sponge in the cushion is prevented from extruding the scrotum; therefore, the cushion has a concave notch on the appearance, and in an area with much sand and dust, the concave notch is easy to accumulate dust and is not easy to clean; because of the sensitive reproductive health issues associated with this construction, some consumers use this product without knowing it, and the gaps in the cushion expose the consumer's privacy. If the concave breathable structure is encapsulated by the seat fabric, the privacy of consumers can be protected; however, the seat fabric is generally made of relatively soft materials such as cloth and leather, and the fabric layer on the periphery of the concave breathable structure is easy to sink due to the fact that no supporting mechanism is arranged, so that appearance defects of the product are caused. In addition, the concave ventilating structure is in a dark closed environment after being encapsulated by the seat fabric layer, and a living place is easily provided for microorganisms such as bacteria and the like in wet weather.

The elastomeric filling, such as a sponge, inside the seat can provide a place for microbes, such as bacteria, to live.

Bamboo and wood materials encapsulated by the seat fabric layer, such as wood boards and battens inside the sofa, are in a closed environment, and can provide living places for microorganisms such as mold and the like in wet weather, so that the sofa is not good for human health.

According to the report of science popularization China, the title of an article indicates that a woman cannot sit on the hot stool?, the woman can often sit on the hot stool to cause urethritis, and the woman often sits on the hot stool to provide a growing hotbed for bacteria at the perineum to cause bacterial infection.

Conventional seats, such as office chairs, sofas, car seats, etc., are typically provided with elastomeric structures. The elastic body structure is a structure which adopts elastic materials such as sponge and the like as an inner layer and adopts materials such as cloth, leather and the like as an outer layer and is arranged at the position where the seat is contacted with a human body, such as a headrest, a back cushion, a seat cushion, an armrest cushion and the like. The bottoms of the elastomer structures are connected with the seat body, the seat needs to be washed or placed under the sunlight for sterilization after being used for a certain time, and most of the elastomer structures cannot be detached and are difficult to clean, such as office chairs and sofas made of leather fabrics, and seats of vehicles, ships and airplanes, and the like, and as time goes on, more and more dirt is generated, which is not good for human health.
