[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Specific examples are given below.

[0026] See also Figure 1 、 Figure 2 and Figure 3 The utility model provides a detachable coil condenser and its air source heat pump water heater, including a coil body 1, a limiting mechanism 2 is provided on both sides of the outside of the coil body 1, and the two limiting mechanisms 2 are rotationally symmetrical along the axis of the coil body 1. The limiting mechanism 2 includes a limiting side plate 21, and the side wall of the limiting side plate 21 is provided with a plurality of arc-shaped bayonet holes 22. The plurality of arc-shaped bayonet holes 22 are respectively engaged with the multi-layer outer diameter of the coil body 1. The other side of the limiting side plate 21 is provided with a position control component 3 near the edges of both ends. The limiting mechanism 2 and the outer After the airflow is connected, the heat of the gas flowing in the coil body 1 can be diffused into the surrounding air through the tube wall of the coil body 1, thus realizing the function of the coil. The coil body 1 is restricted by the limiting mechanism 2 on the coil body 1 through the mutual engagement between its outer wall and the limiting mechanism 2 fixed to the external structure. When the coil body 1 fails, the relative restriction between the limiting mechanism 2 and the coil body 1 is removed, and the coil body 1 can be quickly disassembled. The position control component 3 is the main structure for controlling the mutual restriction between the coil body 1 and the limiting mechanism 2.

[0027] Further, such as Figure 1 、 Figure 2 and Figure 3As shown, the position control component 3 includes a central gear 31, and two linkage racks 32 are installed on the outside of the central gear 31. The linkage racks 32 are rotationally symmetrical along the axial direction of the central gear 31. One end of one linkage rack 32 is vertically fixed to the side of the limiting side plate 21. A rotating shaft 33 is fixed between the two central gears 31. The two linkage racks 32 belonging to the position control component 3 are linked under the meshing action of the central gear 31, so that the two linkage racks 32 can perform synchronous and reverse displacement movements, and one end of one linkage rack 32 is fixed to the external structure. The two limiting side plates 21 are fixed to each other, and one end of the other linkage rack 32 is fixed to the side wall of the limiting side plate 21, so that the device can move the two limiting side plates 21 away from each other by approaching the two linkage racks 32 until the arc-shaped bayonet 22 and the coil body 1 are disengaged from each other. After the coil body 1 and the limiting mechanism 2 are disengaged from each other, the coil body 1 can be quickly removed from the device, wherein the two central gears 31 are fixed to the outer wall of the rotating shaft 33, so that the engaging and limiting state between the coil body 1 and the limiting mechanism 2 can be controlled by rotating the rotating shaft 33;

[0028] Further, such as Figure 2 and Figure 3 As shown, the outer portion of the rotating shaft 33 is provided with two sets of U-shaped buckles 34, each set of U-shaped buckles 34 respectively engages with the end face grooves of two of the linked racks 32. The U-shaped buckles 34 mounted on the outer wall of the rotating shaft 33 limit the distance between the two linked racks 32 by engaging the protrusions at both ends of the U-shaped buckles 34 with the end face grooves of the two linked racks 32, thereby increasing the structural stability of the device. Moreover, this structure does not affect the relative displacement between the linked racks 32 or the relative rotation of the central gear 31 and the rotating shaft 33.

[0029] Further, such as Figure 3 As shown, a rack connecting rod 35 is fixedly connected between one end of two adjacent linkage racks 32. Under the action of the rack connecting rod 35, the two linkage racks 32 belonging to the two position control components 3 are linked, thereby increasing the structural stability of the device.

[0030] Further, such as Figure 4 and Figure 5 As shown, the detachable coil condenser and water heater cover 4, the axis of the water heater cover 4 coincides with the axis of the coil body 1, the inner wall of the water heater cover 4 is fixedly connected to the side of the rack connecting rod 35, and the water heater cover 4, which coincides with the axis of the coil body 1, fixes the limiting mechanism 2 through the mutual fixed connection between its side wall and the side wall of the rack connecting rod 35, thereby achieving the relative installation of the water heater cover 4 to the coil body 1;

[0031] Further, such as Figure 4 and Figure 5As shown, one end of the rotating shaft 33 is fixed to the top surface of the inner wall of the water heater cover 4 through a bearing, and the other end of the central gear 31 passes through the bottom of the water heater cover 4. One end of the central gear 31 is fixed with a linkage gear 36, and a ring gear 42 is suspended on the bottom clamp of the water heater cover 4. The ring gear 42 and the linkage gear 36 mesh with each other. The other end of the rotating shaft 33 fixed to the inner wall of the water heater cover 4 through a bearing passes through the outside of the water heater cover 4 and then fixes the linkage gear 36. This makes it possible to control the mutual engagement or separation between the linkage racks 32 of the two position control components 3 connected thereto by rotating the linkage gear 36. When it is necessary to control the separation of the coil body 1 and the limit mechanism 2, first make the two ends of the limit mechanism 2 and the outside The two rotating shafts 33 rotate synchronously in the same direction under the transmission action of the linkage gear 36. At this time, the adjacent linkage racks 32 approach each other until the coil body 1 is disengaged from the arc-shaped bayonet 22 and the coil body 1 can be removed from the water heater cover 4. During this process, the ring gear 42 is kept stationary. When replacing the coil body 1, the two ends of the coil body 1 are first passed through the bottom through-holes, and then the two end rings of the coil body 1 are brought into contact with the bottom surface of the limiting mechanism 2. At this time, the upper and lower positions of the coil body 1 are preliminarily limited. Then, the ring gear 42 is flipped over to restore the limiting mechanisms 2 on both sides, thereby restoring the limiting effect of the position control component 3 on the coil body 1. Finally, the coil body 1 is connected to the air duct outside the device.

[0032] Working principle: After the limiting mechanism 2 is connected to the external airflow, the heat of the gas flowing in the coil body 1 can diffuse into the surrounding air through the tube wall of the coil body 1, realizing the function of the coil, and the coil body 1 realizes the limitation of the coil body 1 by the limiting mechanism 2 through the mutual engagement between its outer wall and the limiting mechanism 2 fixed to the external structure. When the coil body 1 fails, the relative limitation between the limiting mechanism 2 and the coil body 1 is removed, and the coil body 1 can be quickly disassembled. The two linkage racks 32 belonging to the control component 3 are linked under the meshing action of the central gear 31, so that the two linkage racks 32 can perform synchronous reverse displacement movement, and one end of one linkage rack 32 is fixed to the external structure, and the other linkage rack One end of 32 is fixed to the side wall of the limiting side plate 21, which enables the device to move the two limiting side plates 21 away from each other by approaching the two linked racks 32 until the arc-shaped bayonet 22 and the coil body 1 are disengaged from each other, and the coil body 1 can be quickly taken out of the device after the coil body 1 and the limiting mechanism 2 are disengaged from each other, wherein the two central gears 31 are fixed to the outer wall of the rotating shaft 33, which enables the engagement and limiting state between the coil body 1 and the limiting mechanism 2 to be controlled by rotating the rotating shaft 33, and the U-shaped buckle 34 mounted on the outer wall of the rotating shaft 33 limits the distance between the two linked racks 32 by the mutual engagement between the protrusions at both ends and the end surface grooves of the two linked racks 32, Under the action of the rack connecting rod 35, the linkage of the two linkage racks 32 belonging to the two control components 3 is realized. The water heater cover 4, which coincides with the axis of the coil body 1, fixes the limit mechanism 2 through the mutual fixed connection between its side wall and the side wall of the rack connecting rod 35, thereby realizing the relative installation of the water heater cover 4 to the coil body 1. The other end of the rotating shaft 33 fixed to the inner wall of the water heater cover 4 through the bearing passes through the outside of the water heater cover 4 and fixes the linkage gear 36. This makes it possible to control the mutual engagement or separation between the linkage racks 32 belonging to the two control components 3 connected thereto by rotating the linkage gear 36. When it is necessary to control the separation of the coil body 1 and the limit mechanism 2, first disconnect the two ends of the limit mechanism 2 from the outside. Then, the ring gear 42 is rotated, and the two rotating shafts 33 rotate synchronously in the same direction under the transmission action of the linkage gear 36. At this time, the adjacent linkage racks 32 approach each other until the coil body 1 is disengaged from the arc-shaped bayonet 22 and the coil body 1 can be removed from the water heater cover 4. During this process, the ring gear 42 is kept stationary. When replacing the coil body 1, the two ends of the coil body 1 are first passed through the bottom through-holes of the coil body 1, and then the two end rings of the coil body 1 are brought into contact with the bottom surface of the limit mechanism 2. At this time, the upper and lower positions of the coil body 1 are preliminarily limited. Then, the ring gear 42 is flipped over to restore the limit mechanisms 2 on both sides, thereby restoring the limiting effect of the position control component 3 on the coil body 1. Finally, the coil body 1 is connected to the air duct outside the device.
