Secondly, the resistance wire 31 extends along the axial direction which is approximately parallel to the ventilation opening, and the valve 1 and the resistance wire 31 form sliding contact, so that the length of the current flowing through the resistance wire 31 between the valve 1 and the two connecting terminals 32 on the resistance wire 31 can be changed in the process that the valve 1 rotates around the rotating shaft 30 which is perpendicular to the axial direction of the ventilation opening, and the current in the series circuit is changed, so as to trigger alarm according to the magnitude of the current. Of course, the present disclosure does not limit the specific moving manner of the valve 1, and may also select a sliding manner or the like to be disposed at the vent of the cylinder head 10, which is not limited by the present disclosure.

In particular, the first portion 12 may be configured as a circular plate-like structure for covering the vent opening, while the second portion 13 may be a raised plate extending radially outward from the outer edge of the circular plate-like structure, the primary function being to facilitate the arrangement and design of the structure. More specifically, the protruding plate may be formed with a through hole 131 for the resistance wire 31 to fit through, so that the protruding plate and the resistance wire 21 maintain electrical connection during sliding. In other embodiments, for example, an electromagnetic absorption structure may be disposed on the second portion 13, and when the current is applied, the resistance wire 31 can absorb and form an electrical connection with the second portion 13, and on this basis, the second portion 13 may also form a sliding contact with the resistance wire 31 without being separated.

As an alternative to the elastic element 2, it may be configured as a return spring, and in one embodiment, one end of the return spring may be connected to the valve 1, and the other end may be used for connection to the inner wall of the cylinder head 10. For example, the return spring may be configured as a compression spring which is only approximately in the original length state in the non-operating state of the engine, and the valve 1 adjusts the opening degree of the vent opening under the action of the pressure difference between the two sides of the vent opening when the engine is in the operating state, and continuously applies force to the compression spring in the process of adjusting the opening degree. Under the condition that an air filter in the air intake system is blocked, the pressure difference on two sides of the vent reaches a specified threshold value, and the valve 1 overcomes the elastic force of the compression spring to be in a state of closing or about to close the vent under the action of the pressure difference, so that excessive oil gas can be prevented from entering the air intake system under the condition that the air filter is blocked.

Of course, in other embodiments, the elastic member 2 may be configured not as the above-mentioned spring, but as an elastic sheet or an elastic block, etc., which is not limited in any way by the present disclosure and is included in the protection scope of the present disclosure.
The present disclosure also provides an alarm system, which may include an air filter clogging alarm triggering device, a controller (not shown), and an alarm device (not shown), wherein the controller may control the alarm device to alarm according to a trigger signal of the air filter clogging alarm triggering device.
