When the first valve body 10 and the second valve body 20 are relatively slid away by external force, for example, pulling the first valve body 10 and/or the second valve body 20, the first valve body 10 and the second valve body 20 are enclosed. The volume of the valve chamber 30 will become larger, the pressure inside the valve chamber 30 becomes smaller, the pressure inside the valve chamber 30 is made smaller than the external pressure, and the inside forms a negative pressure with respect to the outside, which causes the third check valve 52 to open. The fluid outside the first side of the valve chamber 30 is introduced into the interior of the valve chamber 30 through the third through hole 21, the third check valve 52, and the seventh through hole 431, and in the process, the first check valve 51 is in the process. It is in the off state. The fluid flows into the interior of the valve chamber 30 until the pressures inside and outside the valve chamber 30 are uniform, and at this time, the third check valve 52 is also turned to the off state. When the first valve body 10 and the second valve body 20 are relatively slid by the external force, for example, the first valve body 10 and/or the second valve body 20 are compressed, the first valve body 10 and the second valve body 20 are enclosed. The volume of the valve chamber 30 will become smaller, the pressure inside the valve chamber 30 becomes larger, the internal pressure of the valve chamber 30 is stronger than the external pressure, and the inside forms a positive pressure with respect to the outside, which causes the first check valve 51 to open, so that The fluid flows from the inside of the valve chamber 30 through the first through hole 11, the first check valve 51, and the fifth through hole 421 to the outside of the first side of the valve chamber 30, and at this time, the third check valve 52 is in the off state. The fluid inside the valve chamber 30 is thereby squeezed to the outside of the first side of the valve chamber 30.

The two-way valve 130 is in the second state by rotating the first turntable 42 and the second turntable 43. Referring to FIG. 3, the sixth through hole 422 is in communication with the inlet of the second check valve 61, and the second check valve 61 is The outlet communicates with the second through hole 12, the eighth through hole 432 communicates with the inlet of the fourth check valve 62, and the outlet of the fourth check valve 62 communicates with the fourth through hole 22. When the first valve body 10 and the second valve body 20 are relatively slid away by external force, for example, pulling the first valve body 10 and/or the second valve body 20, the first valve body 10 and the second valve body 20 are enclosed. The volume of the valve chamber 30 will become larger, the pressure inside the valve chamber 30 will become smaller, and the inside of the valve chamber 30 will generate a negative pressure with respect to the outside, and the second check valve 61 will open under the negative pressure, and the valve chamber 30 will be opened. The fluid outside the second side enters the interior of the valve chamber 30 through the sixth through hole 422, the second check valve 61, and the second through hole 12, respectively, and in the process, the fourth check valve 62 is in the off state. The fluid flows into the interior of the valve chamber 30 until the pressure inside and outside the valve chamber 30 is uniform, and at this time, the second check valve 61 is also turned to the off state. When the first valve body 10 and the second valve body 20 are relatively slid by the external force, for example, the first valve body 10 and/or the second valve body 20 are compressed, the first valve body 10 and the second valve body 20 are enclosed. The volume of the valve chamber 30 will become smaller, causing the pressure inside the valve chamber 30 to become larger relative to the outside, causing a positive pressure to be generated inside and outside the valve chamber 30, and the fourth check valve 62 will open under the positive pressure, the fluid The inside of the valve chamber 30 flows to the outside of the first side of the valve chamber 30 through the eighth through hole 432, the fourth check valve 62, and the fourth through hole 22, and at this time, the second check valve 61 is in an off state. The fluid inside the valve chamber 30 is thereby squeezed to the outside of the second side of the valve chamber 30.

From the above analysis, by switching the state of the two-way valve, the fluid outside the first side of the two-way valve can flow through the valve chamber to the outside of the second side, or the fluid outside the second side of the two-way valve can flow through the valve chamber to the first side. external.

Embodiment 2:

The difference between this embodiment and the first embodiment is that the pulled first valve body 10 and the second valve body 20 are returned to the original position by the spring.

Referring to FIG. 2 and FIG. 3, in the embodiment, there is a gap between the two barrel walls of the first valve body 10 and the second valve body 20, and a piston 70 and a spring 80 are disposed in the gap, and the piston 70 and the two are provided. The barrel walls are in close contact with each other, and both ends of the spring 80 are fixed to the barrel wall of the first valve body 10 and the barrel wall of the second valve body 20, respectively. For example, the inner side of the barrel wall of the first valve body 10 is bent toward the barrel wall of the second valve body 20 with the first boss 17 , and the outer side of the barrel wall of the second valve body 20 is bent toward the barrel wall of the first valve body 10 . The two bosses 24 have a certain distance between the first boss 17 and the second boss 24, and both ends of the spring 80 are fixed to the first boss 17 and the second boss 24, respectively. When the first valve body 10 and/or the second valve body 20 are pulled by the external force to cause the first valve body 10 and the second valve body 20 to slide relatively far apart, the spring 80 is elongated. When the external force is stopped, the spring 80 contracts to automatically return the first valve body 10 and the second valve body 20 to their original positions.

Embodiment 3:

The two-way valve in the above embodiment can be used to make various pultrudable products, for example, the product can be a toy, a handicraft or various display products. The following is an example of a two-way valve using a doll toy as an example.

As shown in FIGS. 4 and 5, the toy includes a main body 110, a control portion 120, and a two-way valve 130. In the present embodiment, the main body 110 is the body of the doll, the control unit 120 constitutes the head of the doll, and the two-way valve 130 is mounted on the head of the doll.

The body 110 has an airtight elastic outer casing 111 and particulate matter (not shown) filled in the outer casing. The outer casing 111 has an opening 113 at the neck of the body.

The control unit 120 has a hollow inner cavity 121. The inner wall of the inner cavity 121 is provided with a first positioning structure 122. The first positioning structure 122 can be a latch or a card slot. A second flange 123 is provided on the inner wall of the control portion in the circumferential direction.

The two-way valve 130 is housed in the inner cavity 121 of the control portion, and the first valve body has a first groove 15 and/or a first flange 16 disposed circumferentially on the outer casing (please refer to FIGS. 2 and 3), first The groove 15 and/or the first flange 16 cooperate with the second flange 123. After the two-way valve 130 is installed into the inner cavity 121 of the control portion, the second flange 123 of the control portion is inserted into the first recess 15 or the second flange 123 is abutted against the first flange 16 below. When the control portion 120 rotates, the control portion 120 can rotate around the outer casing of the first valve body, and when the control portion 120 moves upward, the first valve body can be moved upward.

The housing of the state switching device of the two-way valve 130 has a second positioning structure 44 (refer to FIG. 1) that cooperates with the first positioning structure 122. When the first positioning structure 122 is a latch, the second positioning structure 44 can be a A hole that mates with the pin to insert the pin into the hole. When the first positioning structure 122 is a card slot, the second positioning structure 44 can be a bump that engages with the card slot to insert and snap the bump into the card slot. When the head of the figure is rotated, that is, when the control portion is rotated, the control unit causes the state switching device to rotate together, thereby positioning the state switching device to the first state or the second state.

The second valve body of the two-way valve is in sealing communication with the inner portion of the outer casing through the opening 113 of the outer casing. For example, the second valve body has a sealing piece 23 extending around the third through hole and the fourth through hole, and the sealing piece 23 is inserted from the opening 113 of the outer casing. The shoulder of the figure is in close contact with the opening 113 to form a seal, and the third through hole and the fourth through hole of the second valve body communicate with the inside of the main body casing.

Before the puppet is pumping, the particles in the body are loose. The shape of the figure is determined by the shape of the jacket. Even if a pulling or squeezing force is applied to deform a part of the figure, when the external force disappears, the doll will The original shape is restored and cannot be shaped as intended by the user. The figure in this embodiment can be used to pump or inflate the body by turning the head and pulling the head.

The process of pumping the body is as follows: rotating the head of the doll, the rotation of the head drives the state switching device of the two-way valve to be positioned to the first state, pulling the head, and driving the first valve body and the second valve body to be relatively far away. When sliding, the volume inside the valve chamber 30 becomes large, the pressure becomes small, the gas is drawn from the inside of the body into the valve chamber 30, and then the pulling is stopped, and the first valve body and the second valve body are returned to the original position by the action of the spring 80. The volume inside the valve chamber 30 becomes small, the pressure becomes large, and the gas is squeezed from the inside of the valve chamber 30 to the outside of the body. Then, the head is pulled again, and another gas is pumped from the inside of the body into the valve chamber 30, and the above operation is repeated, so that the gas in the body is gradually reduced, that is, the gap between the particles filled in the body becomes small, until the last particulate matter is Squeeze together, tightly hooped together by the elastic outer casing, and the figure changes from the form of Fig. 5 to the form shown in Fig. 6, and the surface of the outer casing may become uneven due to the shape of the particles. Since the outer sleeve has elasticity, a pulling or squeezing external force can be applied to deform a certain part of the doll. When the external force disappears, the deformed portion will still be maintained, forming various shapes, thereby realizing the doll according to the user's assumption. Carry out various shapings.

The process of inflating the body is as follows: turning the head of the doll in the other direction, the rotation of the head drives the state switching device of the two-way valve to be positioned to the second state, pulling the head, driving the first valve body and the second valve body to do Relatively far away from the sliding, the volume inside the valve chamber 30 becomes larger, the pressure becomes smaller, the gas is drawn from the outside of the body into the valve chamber 30, and then the pulling is stopped, and the first valve body and the second valve body are restored by the action of the spring 80. In the home position, the volume inside the valve chamber 30 becomes small, the pressure becomes large, and the gas is squeezed from the inside of the valve chamber 30 to the inside of the body. Then pull the head again, and the other gas is pumped from the outside of the body into the valve chamber 30. The above operation is repeated, so that the gas in the body is gradually increased. Since the outer casing has elasticity, when the gas in the body is sufficient, the outer casing can be inflated. Get up, make the doll show another form, as shown in Figure 7.

Since the toy itself has a two-way valve, it can charge and deflate the inside of the toy, so that the deflated toy can maintain the shape after pultrusion deformation, and then expands after inflation, and the user can control the toy by controlling the amount of inflation. The degree of expansion. These allow the user to change the shape of the toy according to personal preferences and requirements, thereby enhancing the fun of the toy and increasing the user experience.
