[0045] Furthermore, the power element 2 is a linear motor, and the extension and retraction direction of the linear motor is parallel to the transmission rod 5, such as... Figure 2 , Figure 4 , Figure 7 ,in Figure 2 This is an exterior view. Figure 4 , Figure 7 This is a diagram of the internal structure. Figure 4 The linear motor is positioned on one side of the long cylindrical tube 3, avoiding the transmission rod 5 to prevent interference. Figure 7The linear motor is positioned in the center of the long tube 3, and the transmission rod 5 is directly connected to the linear motor, with the linear motor and transmission rod 5 being coaxial.

[0046] Furthermore, both ends of the linear motor are connected to the transmission rod 5, and the linear motor and the transmission rod 5 are coaxial, such as... Figure 8 .

[0047] When only the first peristaltic component and / or the second peristaltic component are provided, that is, the peristaltic component is provided on one side of the power element 2, this utility model can be used as a peristaltic device.

[0048] When only the first and / or second peristaltic components and the third and / or fourth peristaltic components are provided, that is, peristaltic components are provided on both sides of the power element 2, then this invention can only be used as a peristaltic device if the transmission rod 5 is equal to the distance between the rotation point of the first peristaltic rod 1 of the first peristaltic component and / or the second peristaltic rod 8 of the second peristaltic component on the long tube 3 and the rotation point of the third peristaltic rod 12 of the third peristaltic component and / or the fourth peristaltic rod 16 of the fourth peristaltic component on the long tube 3. In other words, when peristaltic components are provided on both sides of the power element 2, the peristaltic components must be in the same direction. Figure 3 , Figure 4 If peristaltic components are provided on both sides of the power element 2, the peristaltic components must be in reverse order, such as... Figure 5 , Figure 6 At this time, this utility model can only be used as a vibration device.

[0049] Peristaltic principle: When the power element 2 is powered on, it drives the transmission rod 5 to reciprocate along the length of the long cylinder 3. The first connecting rod 4 pulls the first peristaltic rod 1 to rotate relative to the long cylinder 3. The end of the first peristaltic rod 1 near the outer wall of the long cylinder 3 moves in an arc. Since the resistance to pushing outward is greater than the pressure to pull back inward, the arc motion of the first peristaltic rod 1 pushes the long cylinder 3 to move. When the end of the first peristaltic rod 1 near the outer wall of the long cylinder 3 moves, it protrudes from the outer wall of the long cylinder 3, thus pushing the long cylinder 3 forward or backward relative to the pipe. This forward or backward movement is peristalsis. The direction of the current in the motor of the power element 2 can realize the conversion between forward and backward movement. The massage depth is the deepest when the first connecting rod 4 moves perpendicular to the transmission rod 5.

[0050] Peristaltic process: Taking the first peristaltic component as an example, when the power element 2 is powered on, it is assumed that the current drives the motor transmission component to move to the right. The transmission rod 5 will push the first peristaltic rod 1 and the second peristaltic rod 8 to the right. Assuming that the transmission rod 5 moves from the leftmost end to the right end, the part where the first peristaltic rod 1 and the first connecting rod 4 are connected extends out from the first opening and contacts the rectal wall or vaginal wall. The transmission rod 5 continues to move to the right. The part where the first peristaltic rod 1 and the first connecting rod 4 are connected exerts a leftward pushing force on the rectal wall or vaginal wall. According to Newton's law of action and reaction, the rectal wall or vaginal wall exerts a rightward pushing force on the peristaltic component, pushing the entire peristaltic device to the right. The transmission rod 5 continues to move to the right, and the part connecting the first peristaltic rod 1 and the first connecting rod 4 reaches its highest point, maximizing the force pushing the entire peristaltic device. The transmission rod 5 continues to move to the right, and the part connecting the first peristaltic rod 1 and the first connecting rod 4 falls back from its highest point until it is completely submerged in the first opening. When the transmission rod 5 reaches the rightmost end, it returns. During the return process, the part connecting the first peristaltic rod 1 and the first connecting rod 4 extends out of the first opening again, contacting the rectal wall or vaginal wall, pushing the entire peristaltic device to the right. When the transmission rod 5 returns to the leftmost end, the entire peristaltic device has completed one cycle. Within one cycle, the part connecting the first peristaltic rod 1 and the first connecting rod 4 pushes against the rectal wall or vaginal wall twice.

[0051] If the motor drives in the reverse direction, the transmission rod 5 moves from the rightmost end to the leftmost end. Its working principle is exactly the opposite of the above. In one cycle, the part where the first peristaltic rod 1 and the first connecting rod 4 are connected pushes the rectal wall or vaginal wall twice, and the entire peristaltic device moves to the left.

[0052] The working principle is the same if the first peristaltic rod 1 is set in a V shape, but the peristaltic rod pushes against the rectal wall or vaginal wall four times in one cycle, the frequency of pushing is higher, and the whole peristaltic device moves faster.

[0053] The operating principles of the second, third, and fourth peristaltic components are the same as those of the first peristaltic component, and will not be repeated here.

[0054] This device can be used as a carrier to move objects, can be equipped with various sensors to sense position and images, and can also be used to install various massage heads at joints to alternately massage different parts of the human body.

[0055] This invention, by incorporating a peristaltic component, a power element 2, a connecting rod, and a transmission rod 5, enables the movement of the power element 2 to drive the long tube 3 to move peristally or massage within a pipe, thus solving the problem of operation within the human body's channels and facilitating massage or drug administration. Of course, this invention can also have other applications. Specifically, it offers the following beneficial effects:

[0056] 1. This utility model, by setting up a peristaltic component, a power element 2, and a transmission rod 5, enables the movement of the power element 2 to drive the long strip tube 3 to move peristally or massage in the pipe, thus solving the problem of operation in the human body pipe and facilitating massage or drug delivery;

[0057] 2. This utility model sets the peristaltic rod in a V-shape, so that both ends of the peristaltic rod can have a peristaltic function;

[0058] 3. This utility model achieves multiple peristaltic points by setting peristaltic rods on both sides of the long strip tube 3, which is more conducive to peristaltic movement;

[0059] 4. This utility model achieves multiple peristaltic points by setting peristaltic rods at both ends of the transmission rod 5, which is more conducive to peristaltic movement;

[0060] 5. In this utility model, the peristaltic rod is set in the shape of a V. Both ends of the V shape can make the long tube 3 move forward. When one end pushes the long tube 3 forward, the other end is retracting. When one end pushes the long tube 3 back, the other end is moving forward. The alternating forward and backward movement makes the long tube 3 move forward continuously.

[0061] In one specific embodiment, multiple sets of peristaltic structures similar to the first peristaltic rod 1 and the second peristaltic rod 8 can be arranged radially along the positions of the first peristaltic rod 1 and the second peristaltic rod 8 on the long strip tube 3, so as to achieve a 360-degree wall-gripping peristaltic movement with the peristaltic structure distributed circumferentially.

[0062] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
