Description

Technical Field

[0001] The invention relates to the technical field of bathing products, and in particular to an armrest structure for a shower seat. Background Art

[0002] With the rapid development of society, people have higher and higher requirements for living standards, especially for home comfort. For example, taking a bath is essential every day. More and more people choose to install showers at home to improve the convenience and comfort of bathing.

[0003] At present, most of the showers are standing showers, which are not suitable for people with weak constitution or the elderly. It is said that if a longer shower is needed, these devices are not very suitable for them, and may easily lead to accidents or physical exhaustion in special groups during bathing.

[0004] Chinese patent CN207613689U discloses a sitting shower with a safety handrail, but the safety handrail of the shower has at least one of the following defects: 1. Since the handrail is fastened by setting a fastening screw on a plane perpendicular to the axis of the handrail body, the fastening screw is very likely to loosen and bend due to fatigue after continuous pressure-bearing use and folding and unfolding, thereby affecting the safe use of the handrail. 2. The shower with the safety handrail cannot connect and install a spray structure on the handrail fixing part. For some frail elderly bathers, who need to sit for a long time to shower, the mist spray water sprayed by the upper spray arm or the top spray shower is difficult to spray directly to the legs and feet of the lower body. Therefore, in the cold winter, when the mist spray water on the upper part of the bather flows from the top to the lower body, the water temperature gradually decreases to cold water, which is easy to make the bather catch a cold, which is not conducive to the bather's health.
