As shown in fig. 1, which is a simple structure of the present invention, when the heat pump is used to heat water in the water storage cavity 1a in the tank 1, first the first motor 18 is started to drive the first bevel gear 17b to rotate, because the first bevel gear 17b is engaged with the second bevel gear 17a, the first motor 18 drives the lower shaft 111 and the lower cross bar 11 to rotate, because the sleeve 15 is rotatably engaged with the lower cross bar 11 through the lower rotary block 151, the sliding rod 14 is rotatably engaged with the upper cross bar 10 through the upper rotary block 141, the sleeve 15 is slidably connected with the sliding rod 14 through the limit slider 142, so that the upper shaft 101 also rotates along with the lower shaft 111, and the spiral pipe 16 connected to the sliding rod 14 and the sleeve also rotates in the tank 1; because the first gear 13 is meshed with the external gear 12, the first gear 13 is fixedly connected with the sliding rod 14 through the upper rotating block 141, when the upper shaft rod 101 rotates, the first gear 13 drives the upper rotating block 141 to rotate, the upper rotating block 141 drives the sleeve 15 to rotate through the sliding rod 14, and the spiral air pipe 16 also rotates; so that the spiral air tube 16 can be better contacted with the water in the water storage chamber 1 a.
Due to the rotation of the upper shaft rod 101, the first protruding rod 9 is driven to rotate around the upper shaft rod 101 through the radial rod 20, and due to the fact that the first protruding rod 9 slides in the first sliding groove 8b, the upper shaft rod 101 can drive the piston 7 to reciprocate left and right in the cylinder 3 through the connecting rod 8 in a rotating mode, when the piston 7 moves rightwards, air in the air cavity 3a is compressed to generate heat, the heat enters the spiral air pipe 16 through the one-way valve 19, the first through hole 3b, the first annular groove 3c, the second through hole 10a, the second annular groove 10b and the third through hole 14a, heat exchange is carried out with water in the water storage cavity 1a in the moving process of the spiral air pipe, the water is heated, and then the heat is discharged from the spiral air pipe 16 through the sixth through hole 15a, the fourth annular groove 11b, the fifth through hole 11a, the third annular groove 2a and the fourth through hole 2b through the pressure valve 2929.
When the piston 7 moves to the right end of the cylinder 3, the left shoulder 8a pushes the second slider 21 to move upward against the first spring 23 under the action of the left inclined surface 21a, the ratchet 24 is driven to rotate under the action of the first ratchet plate 26, so that the valve flap 6 is driven to rotate 90 degrees through the transmission shaft 5 (as shown in fig. 6), the air inlet 32 is opened, at this time, the connecting rod 8 drives the piston 7 to move leftward, air is sucked into the air cavity 3a, and when the left shoulder 8a leaves the protrusion 213, the second slider 21 descends under the action of the first spring 23, the ratchet 24 is kept still under the action of the second ratchet plate 25 and the front spring 27b, the air inlet 32 is kept in an opened state, and because the area of the air inlet 32 is large, the resistance is small when the piston 7 moves leftward, the air inlet amount is sufficient, and the efficiency of the heat pump is improved.
When the piston 7 moves to the leftmost end leftwards, the right shoulder 7a pushes the second slider 21 to move upwards against the first spring 23 under the action of the right inclined surface 21b, and the ratchet 24 is driven to rotate under the action of the first ratchet plate 26, so that the valve clack 6 is driven to rotate by 90 degrees again through the transmission shaft 5 (as shown in fig. 5), the air inlet 32 is closed, and at this time, the connecting rod 8 drives the piston 7 to move rightwards for the next compression.
When the water level in the box body 1 is low, the first electric push rod 4 extends out to push the bottom plate 2 to ascend, and due to the sliding connection between the sleeve 15 and the sliding rod 14 and the use of the spiral air pipe 16, the sleeve 15 and the sliding rod 14 are contracted and shortened, the spiral air pipe 16 can be immersed in water more, and therefore heat exchange with water can be better carried out.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
