The present application proposes a valve member.

In the embodiment of the present application, as shown in FIGS. 1 to 14, the valve members are a valve chamber 21 having a valve port 23 while communicating with the outside, and a seal 22 provided in the valve chamber 21. A pressure valve 20 provided with a seal 22 that can be moved inside the valve chamber 21 while sealing the valve opening 23, and a pressure valve 20 provided outside the valve chamber 21 that abuts on the valve chamber wall of the valve chamber 21. It includes a drive device for driving the seal 22 so as to cause or seal the valve port 23.

According to the technical proposal of the present application, when the product of this valve member is applied by driving the seal 22 so as to abut against the valve chamber wall of the valve chamber 21 by using the drive device 10, for example, the rice cooker is inactive. When the seal 22 is in a moving state, the seal 22 comes into contact with the valve chamber wall of the valve chamber 21 and retracts from the valve opening 23 under the control of the drive device, and the seal 22 rattles in the valve chamber 21 to generate noise. At the same time, in a state where the rice cooker is operating normally, the resistance of the drive device to the seal 22 is erased to seal the valve port 23 on the seal 22, and the inside of the rice cooker is closed. In the high pressure state, by driving the seal so that the valve chamber wall of the valve chamber 21 is brought into contact with the valve chamber wall and the valve port 23 is opened by the driving device, the "bump" phenomenon is realized and the purpose of uniform rice cooking is achieved. ..

In the present application, the valve member is in a state where the power is off, and the drive device drives the seal 22 so as to bring the seal 22 into contact with the valve chamber wall of the valve chamber and retract the seal 22 from the valve opening 23. Thereby, the above effect can be realized.

As shown in FIGS. 2 and 3, the valve chamber wall of the valve chamber 21 includes an elastically deformable elastic wall 213 provided corresponding to the seal 22, and the drive device 10 includes a main body 111 and a main body. It is understood that the drive source 11 including the push rod 113 capable of reciprocating with respect to 111 and the drive member 12 connected to the push rod 113 (the drive member 12 and the push rod 113 are integrally formed). The push rod 113 is used to drive the drive member 12 so as to reciprocate, and the tip of the drive member 12 in the moving direction is provided corresponding to the outer wall of the elastic wall 213, and the drive member 12 is provided. The valve opening 23 is opened and closed by elastically deforming the elastic wall 213 by 12 to move the seal 22. Here, the seal 22 has a locking portion. At this time, the seal 22 is locked between the valve chamber walls of the valve chamber 21 and abuts on the elastic wall 213. That is, the seal 22 is driven to move by the elastic deformation of the elastic wall 213. In this way, the seal 22 can be locked between the valve chamber walls of the valve chamber 21, and at this time, the seal 22 comes into contact with the elastic wall 213. In another embodiment, it is understood that the drive member 12 may protrude directly into the valve chamber 21 and directly contact the seal 22 without passing through the elastic wall 213. If such an embodiment is adopted, the valve chamber may be adopted. It is necessary to consider the problem of sealing of 21.

In order to simplify the structure of the drive device, the drive source 11 is provided for linearly reciprocating the drive member 12.

Specifically, as shown in FIGS. 2 and 3, the drive source 11 is an electromagnet and an elastic member 13 connected to the core of the electromagnet (when the elastic member 13 is a spring, one end is a coil 312 of the core. It may be installed so as to include (which is connected to one end away from the coil and one end directly or indirectly conflicts with the coil 312). At this time, the push rod 113 is the core of the electromagnet, and the driving member 12 is connected to the core of the electromagnet. When the electromagnet is not energized, the elastic force of the elastic member 13 on the core moves the core away from the coil of the electromagnet to drive the core. When the member 12 abuts on the elastic wall 213 and the seal 22 is at the locking location, i.e., in contact with the valve chamber wall and retracts from the valve opening 23 and energizes the electromagnet, the core continues to compress the elastic member 13. , The drive member 12 is contracted to the rear end in the movement direction of itself, that is, one end of the drive member 12 away from the coil moves in the coil direction, and the valve port 23 can be sealed by the seal 22. When the valve member is applied to the rice cooker, the elastic wall 213 is deformed by the urging force of the elastic member 13 while the rice cooker is not energized to move the seal 22, and the seal 22 is used as the valve of the valve chamber 21. By locking between the chamber walls, the problem that the seal 22 moves in the valve chamber 21 and noise is generated when the rice cooker is moved is solved. When power is supplied to the rice cooker and it is operating, the pressure inside the rice cooker is caused by sealing the valve port 23 on the seal 22 by eliminating the action of the elastic wall 213 on the seal 22 by moving the core of the electromagnet. And when the pressure inside the rice cooker exceeds a preset pressure, the acting force of the core of the electromagnetic valve is immediately eliminated and the reaction force of the elastic member 13 deforms the elastic wall 213 as well. By moving the seal 22, the valve port 23 can be opened and the "bump" phenomenon can be realized. Of course, in another embodiment, by eliminating the acting force by the core of the solenoid valve so as to appropriately change the acting force by the core of the solenoid valve, the valve opening 23 is provided without fixing the seal 22. You may try to achieve the purpose of opening up.

By basically the same principle as the solenoid valve, the drive source 11 may be installed so as to include the electric cylinder and the elastic member 13 connected to the piston rod of the electric cylinder. At this time, the push rod 113 is the piston rod of the electric cylinder, the drive member 12 is connected to the piston rod of the electric cylinder, and when the electric cylinder is not energized, the piston rod compresses the elastic member 13 and is formed by the elastic member 13. The elastic force on the piston rod keeps the piston rod away from the cylinder bore of the cylinder, the drive member 12 abuts on the elastic wall 213, the seal 22 is at the locking point, and when the electric cylinder is energized, the piston rod compresses the elastic member 13. Subsequently, the drive member 12 can be contracted to the rear end in the moving direction of itself, and the valve port 23 can be sealed by the seal 22. This technical proposal can also solve the problem of noise caused by the movement of the seal 22 in the valve chamber 21. At the same time, the phenomenon of "buoyation" can be realized.

By basically the same principle as the solenoid valve, the drive source 11 may be installed so as to include a motor, a transmission rod connected to the motor via a transmission member, and an elastic member 13 connected to the transmission rod. Good. At this time, the push rod 113 is a transmission rod, and the drive member 12 is connected to the transmission rod. When the motor is not energized, the transmission rod compresses the elastic member 13, and the elastic force of the elastic member 13 on the transmission rod causes the transmission rod to move the drive member 12 to the tip of the drive member 12 in the moving direction. The member 12 is in contact with the elastic wall 213, the seal 22 is at the engaging portion, and when the motor is energized, the transmission rod is driven by the motor so that the elastic member 13 continues to be compressed, and the drive member 12 is driven in the movement direction of itself. The valve port 23 can be sealed by the seal 22 by shrinking to the rear end. This technical proposal can also solve the problem of noise caused by the movement of the seal 22 in the valve chamber 21. At the same time, the phenomenon of "buoyation" can be realized. Here, the transmission rod may be provided with a linear rack, and the rotating shaft of the motor may be provided with a gear that meshes with the linear rack. In this way, the linear reciprocating movement of the transmission rod is realized. This structure is simple and practical. Of course, a structure that realizes movement similar to that of a piston may be provided so that the transmission member includes a transmission rod. Of course, the curved movement of the drive member 12 may be realized by providing the transmission rod with an arc-shaped rack that meshes with the gear.

In this embodiment, the drive member 12 and the elastic wall 213 are detachably connected to each other. By providing the drive member 12 and the elastic wall 213 so as to be detachably connected, the stability of the connection between the drive member 12 and the elastic wall 213 can be improved, and the operation of deforming the elastic wall 213 can be further improved. By stably contacting the seal 21 more stably, the first valve port 22 can be opened and closed more stably by the seal 21.

Specifically, the drive member 12 and the elastic wall 213 can be connected by a screw structure or a locking structure. Therefore, the convenience of attaching and detaching the drive member 12 and the elastic wall 213 is improved. Here, the drive member 12 may have a rod-like structure or a plate-like structure.

As shown in FIG. 5, the elastically deformable elastic wall 213 referred to in the present application can be realized by its own elastic structure. For example, the elastic wall 213 is an elastically deformable annular elastic wall surface. May be included, and specifically, a bent wall surface or a wavy surface may be provided. Alternatively, the elastic wall 213 may be provided so as to be manufactured from an elastic material, and for example, it may be selected to manufacture the elastic wall 213 from rubber or silica gel. Of course, the elastic wall 213 may be installed not only to include an elastic structure but also to be manufactured of an elastic material.

As shown in FIGS. 5 and 6, in the present application, the elastic wall 213 is installed so that the engaging chamber 2131 is formed, and the engaging chamber 2131 has the chamber opening 2132 formed on the outer wall surface of the elastic wall 213. An elastic locking edge 2133 extending in the width direction of the engaging chamber 2131 is formed on the edge of the chamber opening 2132, and a connecting portion 1211 connected to the driving member 12 is formed at the tip of the driving member 12 in the moving direction. And a locking head 121 including a position regulating portion 1212 connected to one end of the connecting portion 1211 away from the drive member 12, the position regulating portion 1212 is provided toward the peripheral surface in the moving direction of the connecting portion 1211. The protrusion 1213 is formed, and the protrusion 1213 comes into contact with the inner wall surface of the elastic locking edge 2133. This not only facilitates the attachment and detachment of the drive member 12 and the elastic wall 213, but also abuts the protrusion 1213 on the inner wall surface of the elastic locking edge 2133 to reinforce the stability of the connection between the two and engage them. It is possible to prevent the locking head 121 from coming off from the chamber 2131.

In order to further reinforce the stability of the connection between the locking head 121 and the engaging chamber 2131, the protrusion 1213 and the elastic locking edge 2133 are both provided in an annular shape so that the protrusion 1213 and the elastic locking edge 2133 come into contact with each other. The surface can be increased to reinforce the connection between the two. Of course, in another embodiment of the present application, the protrusions 1213 are provided in a striped shape, and a plurality of protrusions 1213 may be provided.

A guide angle 1213a may be formed at one end of the protrusion 1213 away from the drive member 12 to facilitate the locking head 121 engaging with the engagement chamber 2131. For example, a slope or an arc surface may be provided at one end of the protrusion 1213 away from the driving member 12. This makes it easier for the locking head 121 to be inserted into the engaging chamber 2131.

As shown in FIGS. 3 and 6, in order to facilitate the installation of the locking head 121 and the driving member 12, both may be integrally formed and provided. For example, injection molding may be used, which is simple and practical, and can further reduce the cost. However, it should be noted that the wall thickness of the drive member 12 is kept substantially constant so as to improve the stability of the drive member 12.

In order to improve the stability of the seal 22 contacting the valve chamber wall of the valve chamber 21, the inner wall surface of the valve chamber wall of the valve chamber 21 to which the seal 22 abuts is provided with a recess that matches the outer shape of the seal 22. You may. As a result, the frictional force between the seal 22 and the valve chamber wall is strengthened, and the seal 22 is prevented from coming off the valve chamber wall.

The seal 22 is provided in a spherical shape in order to improve the smoothness of movement of the seal 22 in the valve chamber 21 and the stability of sealing the valve port 23 by the seal 22.

The structure of the valve chamber wall of the valve chamber 21 is generally considered to be provided in a relatively stable structure, and in order to facilitate the installation of the elastic wall 213, the elastic wall 213 is provided separately to provide the valve chamber 21. An opening (not shown) is provided in the valve chamber wall, an annular concave groove 2134 is provided in the peripheral edge of the elastic wall 213, and the groove mouth of the annular concave groove 2134 is in a direction orthogonal to the expansion / contraction direction axis of the drive member 12. The edges that face and form the opening may be connected by sealing the groove wall of the annular recess 2134. In this way, when the elastic wall 213 is elastically deformed, the edge forming the opening has a reaction force against the groove wall of the annular concave groove 2134, and the elastic wall 213 is prevented from being detached from the opening, and the valve chamber is prevented. The steam in 21 is prevented from entering the drive device. Of course, in other embodiments of the present application, the elastic wall 213 may be installed so as to be integrally formed with the other valve chamber walls of the valve chamber 21. In this case, the elastic wall 213 may be elastically deformed by installing the elastic wall 213 so as to have an elastic structure.

The cross section of the portion is wider than the cross section of the portion where the protruding rib 1131 is not provided. The drive device 10 further includes a drive member 12, which is located in the axial direction of the push rod 113 with the first groove 1221 into which the protruding rib 1131 is inserted along the side of the push rod 113 in the moving direction.

That is, the connection between the push rod 113 and the drive member 12 is realized by engaging the protruding rib 1131 and the locking groove 122. Therefore, not only the connection efficiency between the drive member 12 and the push rod 113 can be improved, but also the stability of the connection between the two can be ensured, and the structure is simpler.
