Problems solved by technology

[0004] Although this kind of safety helmet has good air permeability, it is very easy to cause heat loss from the user's head at low temperature in cold winter and the cold is unbearable, especially in extremely cold countries such as Europe, America, and mainland China, so it is necessary to purchase another non- Breathable helmets are used, but generally non-breathable helmets can meet the needs of keeping warm compared with breathable helmets, but cold air can also enter through the brim of the helmet, which cannot achieve complete warmth

Embodiment Construction

[0016] The invention is an air flow control valve body gain device of a ventilating safety helmet, such as figure 1 As shown, it includes an airflow control valve body device 20 arranged behind the large round hole 101 at the top of the ventilating safety helmet body 10. It includes: a support piece 201 extending from a rail piece 201a, and a rain shield is provided on both sides of the support piece 201. Plate 201b can prevent rainwater from flowing into large circular hole 101, and support sheet 201 can also strengthen the force of deflector 40 (below in detail); A valve body 202 comprises a rail block 202a, is arranged on the valve 202b of rail block 202a both sides , a stud 202d arranged on the top of the rail block and a concave rail 202c arranged on the bottom plate of the rail block, the rail piece 201a of the support piece is arranged in the concave rail for reciprocating movement; a shroud 40 is set An elongated hole 401 is formed on the top surface of the ventilating...

Abstract

The invention is a gain apparatus for airflow control valve body of ventilative safety cap, comprising an airflow control valve body equipped behind the big circular hole on the top of the ventilative safety cap, a valve plate, a cover casing with orifices, and a warming sheath. The airflow control valve body can be adjusted according to temperature variation to achieve the goal of cool in summer and warm in winter. The movable valve can be pushed forward in summer to make the air flow out of the cap from the space between the valve and the rain baffle, and can be pushed backward in winter to form an enclosure with the rain baffle and block heat radiation from the safety cap.

Description

(1) Technical field [0001] The present invention relates to a ventilating safety helmet, in particular to a gas flow control valve body gain device of a ventilating safety helmet, which can be adjusted to adapt to changes in temperature, so as to realize ventilation and heat preservation to achieve the effect of cooling in summer and warming in winter. (2) Background technology [0002] A safety helmet is a cap body that protects the driver's head. The general safety helmet is known to everyone. The cap body is designed to be airtight. In the high temperature of the summer, the user's head must be difficult to withstand the high temperature and cannot dissipate heat. , is an imperfect product. [0003] In order to improve and overcome the lack of sultriness, the industry has developed various structural designs of ventilating helmets to meet the needs of users. The inventor also developed several helmets with ventilating effects a few years ago, which have excellent For exa...
