DETAILED DESCRIPTION

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] Embodiment 1

[0020] like Figures 1 to 6 As shown, the water circulation electric blanket comprises a blanket body 1 and a headrest 2, wherein a circulating water pipe 3 is pulled inside the blanket body 1, the headrest 2 comprises a frame 21, a water inlet tank 22, a water outlet tank 23, a driving device and a heating unit, the water inlet end and the water outlet end of the water pipe are pulled out of the blanket body 1 and are respectively connected to the water inlet tank 22 and the water outlet tank 23, the driving device comprises a plurality of water pumping units fixed to the frame 21, the water pumping units comprise a water guide cylinder 24, a spiral water guide wheel 25 rotatably connected to the water guide cylinder 24 and a plurality of The water spray structure 4 is located on the water guide cylinder 24, the spiral water guide wheel 25 is made of iron material, the water inlet end of the water guide cylinder 24 is connected to the water inlet box 22, and the water outlet end of the water guide cylinder 24 is connected to the water outlet box 23. The water spray structure 4 includes a valve body 41 located on the circumference of the water guide cylinder 24, a fixed valve block 42 fixed in the valve body 41, and a movable valve block 43 slidably connected in the valve body 41. The movable valve block 43 is close to the inner cavity of the water guide cylinder 24, and the movable valve block 43 has a built-in adsorption piece of permanent magnetic material. The fixed valve The end of the block 42 close to the movable valve block 43 has a contraction portion 44 with a diameter smaller than the inner cavity of the valve body 41. The contraction portion 44 is sleeved with a return spring 45 connecting the fixed valve block 42 and the movable valve block 43. The fixed valve block 42 is provided with a plurality of water spray holes 46. The movable valve block 43 is provided with a water inlet hole 47 connecting the inner cavity of the water guide cylinder 24 with the inner cavity of the valve body 41 outside the contraction portion 44. The outlet of the water inlet hole 47 is located on the end surface of the contraction portion 44 of the fixed valve block 42. The return spring 45 can The movable valve block 43 can be pressed against the end face of the contraction portion 44 of the fixed valve block 42; a gelatinous sealing bag skin 48 covering the outside of each water spray structure 4 is sleeved on the skeleton 21, and the water flowing out of the water spray hole 46 can flow back to the water inlet tank 22. There are two water pump units, and a driving gear 49 is rotatably connected to the skeleton 21. A driven gear 51 is fixedly arranged on the axle of the spiral water guide wheel 25. The two driven gears 51 are meshed with the driving gear 49 at the same time, and the driving gear 49 is connected to a motor.

[0021] In other words, the sealing bag skin 48 is wrapped around the frame 21, and the water pump unit acts as a support for the headrest 2. The water spray structure 4 on the water pump unit is only distributed in a local position where the water guide tube 24 is facing upward, and the user's head, neck, shoulders and other positions can be close to the water spray structure 4 of the water pump unit.

[0022] A plurality of support sheets 52 are arranged alternately outside the water guide tube 24, and the water spray structure 4 is located between adjacent support sheets 52. The support sheets 52 can ensure that there is a certain gap between the sealing bladder skin 48 and the outlet of the water spray hole 46 in a naturally tensioned state; the sealing bladder skin 48 will not block the outlet of the water spray hole 46 under the action of the support sheets 52, and a certain gap can be maintained between the water spray hole 46 and the sealing bladder skin 48. In this way, when the water flow is sprayed onto the sealing bladder skin 48, a certain impact force can be formed on the sealing bladder skin 48.

[0023] The heating unit is located in the water inlet box 22. From the water inlet end of the water guide cylinder 24 to the water outlet end of the water guide cylinder 24, the pitch of the spiral blades on the spiral water guide wheel 25 gradually decreases, that is, the thickness of the spiral blades of the spiral water guide wheel 25 gradually increases, ensuring that the loss of water in the running path due to water spraying will not significantly affect the water pressure, and each water spray hole 46 along the axial direction of the water guide cylinder 24 can always spray water with a certain pressure.

[0024] The movable valve block 43 is normally in a state of being against the fixed valve block 42 under the action of the return spring 45. The outlet of the water inlet hole 47 is located on the end face of the movable valve block 43. The outlet of the water inlet hole 47 on the movable valve block 43 can be blocked by the fixed valve block 42, and the water in the water guide cylinder 24 cannot be sprayed out from the water spray hole 46. When the spiral blade of the spiral water guide wheel 25 approaches and is located on the inner side of the movable valve body 41, the movable valve body 41 is attracted by the magnetic force and moves away from the fixed valve body 41. The water in the water guide cylinder 24 can enter the contraction part 44 of the fixed valve body 41 through the water inlet hole 47, and then enter from the entrance of the water spray hole 46, and be sprayed from the outlet of the water spray hole 46 to the inner wall surface of the sealing bladder skin 48. With the rotation of the spiral water guide wheel 25, the spiral blade of the spiral water guide wheel 25 can be intermittently close to each movable valve block 43, so that the water spray hole 46 is intermittently opened, forming an intermittent water impact force on the inner wall surface of the sealing bladder skin 48.

[0025] Embodiment 2

[0026] The difference from the first embodiment is that Figure 7 As shown, the inlet of the water spray hole 46 is located on the circumferential surface of the contraction portion 44 of the fixed valve block 42. In this way, compared with the first embodiment, the sensitivity of the reciprocating motion of the movable valve body 41 can be improved to ensure the excitation frequency and excitation intensity of the water flow impact.

[0027] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
