[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] A preferred embodiment of a cold storage evaporator that is easy to clean provided by the utility model is as follows: Figures 1 to 6 As shown: an evaporator for cold storage which is easy to clean, comprises a shell 1, a mounting groove 2 is arranged on the surface of the shell 1, a mounting rod 3 is slidably connected inside the mounting groove 2, a retaining ring 4 is fixedly connected to the surface of the mounting rod 3, one end of the retaining ring 4 is provided with two groups of clamping rings 5 ​​which are in contact with the surface of the mounting rod 3 and are slidably connected to the shell 1, one side of the two groups of clamping rings 5 ​​are fixedly connected with springs 6 which are fixedly connected to the shell 1, a connecting block 7 is fixedly connected to the tail of the mounting rod 3, and a fan mesh cover 8 is fixedly connected to the tail of the connecting block 7.

[0028] In this embodiment, the centers of the assembly slot 2 and the fan grille 8 are located at the same point, and the assembly rod 3 and the assembly slot 2 are in close contact, which can prevent the assembly rod 3 from shaking inside the assembly slot 2 and affecting the stability of the fan grille 8.

[0029] In this embodiment, the back side of the clamp ring 5 is in contact with the retaining ring 4, and the clamp ring 5 and the retaining ring 4 are arranged parallel to each other. By setting the retaining ring 4, the retaining ring 4 can be aligned with the assembly rod 3, so that the assembly rod 3 cannot be pulled out from the inside of the assembly groove 2 when clamped by the clamp ring 5.

[0030] In this embodiment, both ends of the clamp ring 5 are inclined, and the inclined surface of the clamp ring 5 is located on the rotation trajectory of the assembly rod 3. When the assembly rod 3 rotates, it will squeeze the inclined surface of the clamp ring 5 to open the clamp ring 5, so that the assembly rod 3 can be re-engaged into the interior of the clamp ring 5.

[0031] In this embodiment, the centers of the clamp ring 5 and the assembly rod 3 are located at the same point, and a non-slip rubber gasket is provided on one side of the clamp ring 5 close to the assembly rod 3, so that the clamp ring 5 can better clamp and limit the assembly rod 3. Example

[0032] Based on Example 1, a preferred embodiment of a cold storage evaporator that is easy to clean provided by the utility model is as follows: Figures 1 to 6 As shown: a slider 9 is slidably connected inside the shell 1, a connecting plate 12 is fixedly connected to one side of the slider 9, a top cover 13 that fits the top of the shell 1 is fixedly connected to the top of the slider 9, a block 10 located below the connecting plate 12 is slidably connected to the surface of the shell 1, and a screw 11 is threadedly connected to the inside of the connecting plate 12.

[0033] In this embodiment, the slider 9 is a "T" structure, and the top cover 13 forms a snap-fit ​​structure with the shell 1 through the slider 9. The slider 9 is controlled to slide to the left and slide out of the interior of the shell 1, so that the shell 1 can be quickly disassembled, thereby facilitating the cleaning of the interior of the shell 1.

[0034] In this embodiment, the block 10 and the connecting plate 12 are perpendicular to each other. The connecting plate 12 and the block 10 are both provided with threaded grooves matching the size of the screw 11. When the screw 11 embedded in the block 10 is screwed out, the block 10 loses the engagement of the screw 11 and automatically slides downward under the action of gravity. At this time, the connecting plate 12 is no longer fixed by the block 10, so that the slider 9 can also become a slidable state.

[0035] The working principle and use process of the utility model are as follows: first, when the fan mesh cover 8 needs to be disassembled to clean the fan, the fan mesh cover 8 can be rotated forcefully to control the assembly rod 3 to slide inside the assembly groove 2. When the assembly rod 3 slides, a thrust is applied to the inner ring of the clamp ring 5 to make it slide along the shell 1. At this time, the assembly rod 3 can slide out and contact the clamp ring 5, and then the assembly rod 3 can be pulled out from the inside of the assembly groove 2. When the fan mesh cover 8 needs to be assembled after cleaning, the assembly rod 3 is aligned with the assembly groove 2 and embedded therein, and then the fan mesh cover 8 is rotated to control the assembly rod 3 to rotate. When the assembly rod 3 rotates, the clamp ring 5 is opened by squeezing the inclined surface of the clamp ring 5, so that the assembly rod 3 is re-engaged into the inside of the clamp ring 5. By setting the retaining ring 4, the retaining ring 4 can be used for the assembly rod 3, so that the assembly rod 3 cannot be pulled out from the inside of the assembly groove 2 when clamped by the clamp ring 5.

[0036] When the inside of the shell 1 needs to be cleaned, the screw 11 embedded in the block 10 can be screwed out, and the block 10 loses the engagement of the screw 11 and automatically slides downward under the action of gravity. At this time, the connecting plate 12 is no longer fixed by the block 10, so that the slider 9 can also become a slidable state, and the top cover 13 is pulled sideways to control the slider 9 to slide to the left and slide out of the shell 1, so that the shell 1 can be quickly disassembled, thereby facilitating the cleaning of the inside of the shell 1.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
