[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: an electric heating sleeve, comprising: a sleeve 1; an opening is provided on one side of the sleeve 1, an external connection mechanism is provided on the outer wall of the sleeve 1 for auxiliary installation and wiring, a plurality of electric heating plates 7 are sequentially fixed on the inner wall of the sleeve 1, two symmetrical auxiliary arms 2 are fixed on the outer wall of the sleeve 1, two symmetrical placement heads 3 are fixed at one end of the auxiliary arms 2, a rotating column 4 is rotatably connected between the two placement heads 3, a socket 5 is provided on the outer wall of the rotating column 4, and a bolt 6 is locked between the two rotating columns 4;

[0021] The sleeve 1 is made of flexible steel. It can be bent and scaled through the opening settings, and thus can wrap steel cartridge filters of more thicknesses. An external mechanism is used to assist the stable installation of the sleeve 1 and the external wire 10. After the sleeve 1 wraps the cartridge filter, an electric heating plate 7 is used for heating and heat preservation to prevent the internal water from condensing and affecting the use. When the sleeve 1 is wrapped and installed, the locking bolts 6 are locked by the rotating columns 4 of the two auxiliary arms 2. Both of the two auxiliary arms 2 are inserted with the locking bolts 6 through the rotating columns 4 that rotate through the two placement heads 3. Due to the rotatability of the rotating columns 4, the socket 5 is not prone to excessive deviation, which affects the locking of the bolts 6.

[0022] Preferably, the external mechanism includes a control box 8, a connecting plate 9, and a connecting wire 10. The control box 8 is fixed to the outer wall of the sleeve 1, and the power connection end of the electric heating plate 7 is connected to the power-on control end of the control box 8.

[0023] The control box 8 is also made of steel, and it is used to control the power input to the electric heating plate 7 to ensure the normal operation of the electric heating plate 7.

[0024] Preferably, a connecting wire 10 for an external power supply is fixed to the power input end of the control box 8.

[0025] The power controlled by the control box 8 is externally input through the connecting wire 10, and an external power supply line is connected through the connecting wire 10.

[0026] Preferably, the connecting plate 9 is fixed to the outer wall of the control box 8, and a plurality of through holes are sequentially formed in the outer wall of the connecting plate 9.

[0027] Through the cooperation of the connecting plate 9 and its through holes, the entire heating sleeve and the filter cartridge can be further stably fixed and integrated.

[0028] A specific application of this embodiment is as follows: The sleeve 1 is sleeved on the outer wall of a cartridge filter smaller than its wrapping range, so that the electric heating plate 7 is in contact with the outer wall of the steel cartridge filter. Then, the locking bolts 6 can be locked between the two rotating columns 4 of the auxiliary arm 2, so that the opening on one side of the sleeve 1 is tightened and hugs the cartridge filter, and the heating operation is stably carried out. When the locking bolt 6 is tightened to lock the sleeve 1, the opening of the sleeve 1 will shrink, and the auxiliary arm 2 will move synchronously. The socket 5 of the rotating column 4 will also displace. Due to the rotatability of the rotating column 4, it can rotate according to the situation during the displacement process, so that the sockets 5 of the two rotating columns 4 can be better aligned, which is convenient for locking the bolts 6. During the installation of the sleeve 1, the connecting plate 9 and the installation equipment or wall, etc. can be further fixed together through the through holes of the connecting plate 9 and additional screws, further fixing the entire heating sleeve. When heating is required for operation, the power supply is externally connected through the connecting wire 10 of the control box 8, and the power is controlled to be input to the electric heating plate 7 inside the sleeve 1, so that the electric heating plate 7 generates heat to ensure that the inside of the cartridge filter does not condense and can be used normally in a relatively cold situation.
