The existing steam valve is complex in adjusting structure, so that the sealing performance of the valve seat is low.

Disclosure of Invention

The invention aims to provide a steam valve and an electric cooker, which aim to solve the problem of low sealing property of a valve seat.

In order to realize the purpose, the specific technical scheme of the steam valve and the electric cooker is as follows:

a steam valve comprises a valve seat, wherein a main cavity is formed in the valve seat and is provided with a valve port and an exhaust hole; a valve core is arranged in the valve seat, a driving mechanism is arranged outside the valve seat, and the driving mechanism conducts force through a magnetic field so as to drive the valve core to slide along the main cavity; when the valve core is abutted against the valve port, the valve port is closed; when the valve core is far away from the valve port, the valve port is opened, and the valve seat exhausts air through the exhaust hole.

Furthermore, the driving mechanism comprises an electromagnet, and the valve core is fixedly connected with a permanent magnet and drives the valve core to move.

Further, a sleeve is arranged on the inner wall of the valve seat, and the valve core is sleeved on the sleeve and slides along the sleeve.

Further, the exhaust holes are arrayed on the end face of the valve seat around the circumference of the sleeve.

Furthermore, the valve seat is provided with an air inlet at one end of the sleeve far away from the exhaust hole, the diameter of the air inlet is larger than that of the valve seat, and the valve port is positioned between the air inlet and the sleeve.

Furthermore, the valve seat forms a bottom plate at one end of the air inlet close to the sleeve, and when the valve core closes the valve port, the valve core is abutted to the bottom plate.

Furthermore, a through hole is formed in the center of the exhaust hole of the valve seat and communicated with the inner cavity of the sleeve.

Further, the valve core comprises a main body sleeved on the sleeve, and a convex edge is formed on the inner edge of the main body.

Further, sleeve outside cover is equipped with spacing muscle, and when the valve port was kept away from to the case, spacing muscle and main part butt.

An electric cooker comprises the steam valve.

The steam valve and the electric cooker have the following advantages:

1. the driving device is arranged outside the valve seat, so that the sealing performance of the valve seat is not damaged;

2. the steam valve with the variable steam channel can adjust the size of the steam channel according to needs in the cooking process, so that when large-firepower cooking is ensured, the large steam channel is adopted to confirm that rice milk in the cooker does not overflow, and when small-firepower cooking is carried out, the small steam channel is adopted to ensure that the energy efficiency of the whole machine is not reduced.

The exhaust holes 12 are circumferentially arrayed around the sleeve 5 on the end face of the valve seat 1. The valve seat 1 is provided with an air inlet 13 at one end of the sleeve 5 far away from the exhaust hole 12, the diameter of the air inlet 13 is larger than that of the valve seat 1, and the valve port 11 is positioned between the air inlet 13 and the sleeve 5. The valve seat 1 has a bottom plate 6 formed at one end of the inlet port 13 adjacent to the sleeve 5, and the valve element 2 abuts against the bottom plate 6 when the valve element 2 closes the valve port 11. And the electromagnet 3 is arranged outside the bottom plate 6.

The valve seat 1 is provided with a through hole 14 at the center of the exhaust hole 12, and the through hole 14 is communicated with the inner cavity of the sleeve 5 so as to ensure the basic steam discharge amount.
