[0022] In order to make the technical solution and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The utility model provides a technical solution: Figure 1 - Figure 5 The utility model discloses a protective device for a ceramic filter, comprising a protective cover 1, a storage mechanism 2 is provided on the bottom side of the protective cover 1, the storage mechanism 2 comprises a storage groove 21 with a T-shaped cross-section, and the storage groove 21 is filled with an adhesive, the storage groove 21 is opened on the bottom side of the protective cover 1, a sealing member 22 is provided in the bottom end opening of the storage groove 21, and a driving mechanism 3 is provided on the protective cover 1.

[0024] In this embodiment, when installing the improved ceramic filter protection device, the operator can directly put the protective cover 1 on the outer peripheral side of the ceramic filter. At this time, the ceramic filter fits the outer wall of the protective cover 1, and at the same time, the bottom side of the protective cover 1 fits the circuit board. Then the operator maintains the pressing strength of the protective cover 1 with one hand, and pulls the driving mechanism 3 upward with the other hand to form a negative pressure cavity in the storage tank 21, and pushes the sealing member 22 into the storage tank 21 to release the closed state of the opening of the storage tank 21, so that the adhesive in the storage tank 21 flows out of the storage tank 21. After the operator maintains the pressure of the protective cover 1 for a period of time, the adhesive bonds the protective cover 1 to the circuit board.

[0025] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, both ends of the protective cover 1 are arranged in an arc shape, a plurality of guide grooves 4 are opened on the top side of the protective cover 1, and the spacing between two adjacent guide grooves 4 is equal, a plurality of heat dissipation plates 5 are relatively fixedly installed on the front and rear sides of the protective cover 1, and the spacing between two adjacent heat dissipation plates 5 is equal, and the protective cover 1 is made of a heat conducting plate;

[0026] In this embodiment, the guide groove 4 and the heat sink 5 can expand the contact area between the external airflow and the protective cover 1, so that the ceramic filter can quickly exchange heat with the external airflow through the protective cover 1, avoiding the installation of the protective cover 1 to reduce the heat dissipation rate of the ceramic filter.

[0027] In a further preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, the plugging member 22 includes a soft ring 221, which is disposed in the bottom opening of the storage groove 21, and the inner and outer ring walls of the soft ring 221 are both interference fit with the inner wall of the opening of the storage groove 21;

[0028] In this embodiment, the interference fit between the soft ring 221 and the inner wall of the storage groove 21 allows a certain friction force to be generated between the soft ring 221 and the inner wall of the opening of the storage groove 21, thereby constraining the soft ring 221 to be positioned within the opening of the storage groove 21 while sealing the opening of the storage groove 21 with the sealing cover.

[0029] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the driving mechanism 3 includes a plurality of soft rods 32 with a T-shaped cross section, a plurality of connecting holes 31 with a cross-shaped cross section are opened on the top side of the protective cover 1, and the plurality of connecting holes 31 are divided into two groups and arranged at the front and rear sides of the plurality of guide grooves 4, the interior of the connecting hole 31 is communicated with the interior of the storage groove 21, and the soft rods 32 are arranged in the corresponding connecting holes 31 and are interference fit with the inner wall of the corresponding connecting hole 31;

[0030] In this embodiment, the interference fit between the soft rod 32 and the inner wall of the connecting hole 31 creates a certain friction force between the soft rod 32 and the inner wall of the connecting hole 31, which not only limits the position of the soft tube in the connecting hole 31, but also blocks the top opening of the connecting hole 31 to prevent the soft tube from sliding in the connecting hole 31 and affecting the storage of adhesive in the storage groove 21.

[0031] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a limit strip 33 with a U-shaped cross section is provided at the middle position of the top side of the protective cover 1, and both ends of the limit strip 33 are inserted into the corresponding guide groove 4 and contact the inner wall of the corresponding guide groove 4, and a connecting rope 34 is fixedly installed and penetrated at the position corresponding to the soft rod 32 in the limit strip 33, and both ends of the connecting rope 34 are inserted into the corresponding connecting hole 31 and fixedly connected to the corresponding soft rod 32 through an adhesive, and the top of the soft rod 32 is a hemispherical setting;

[0032] In this embodiment, after the protective cover 1 is put on the ceramic filter, the operator buckles the limit bar 33 out of the guide groove 4, and then the soft rod 32 can be pulled synchronously through the limit bar 33. The pulling force of the operator on the soft rod 32 offsets the friction between the soft rod 32 and the inner wall of the connecting hole 31, and the soft rod 32 moves upward. The space in the connecting hole 31 on the bottom side of the soft rod 32 expands, and a negative pressure cavity is synchronously formed in the connecting hole 31 and the storage groove 21. As the soft rod 32 moves upward, the negative pressure cavity in the connecting hole 31 and the storage groove 21 is synchronously enhanced, thereby making the soft rod 32 easy to operate.

[0033] In a further preferred embodiment of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, a plurality of rubber rods 222 are relatively fixedly mounted on the bottom side of the soft ring 221, and the spacing between two adjacent rubber rods 222 is equal, and both ends of the rubber rods 222 are hemispherical.

[0034] In this embodiment, when filling the storage tank 21 with adhesive, the operator first pours a specific amount of adhesive into the storage tank 21 from the opening of the storage tank 21, and then inserts the soft ring 221 into the opening of the storage tank 21 until the rubber rod 222 and the protective cover 1 contact each other, and the soft ring 221 just blocks the bottom opening of the storage tank 21 and will not be directly inserted into the storage tank 21;

[0035] When a negative pressure cavity is formed in the storage groove 21, an upward pulling force can be applied to the soft ring 221, and as the soft rod 32 moves upward, the pulling force on the soft ring 221 gradually increases, thereby offsetting the friction between the soft ring 221 and the inner wall of the storage groove opening, and finally pulling the soft ring 221 into the storage groove 21 to release the closed state of the storage groove 21 opening.

[0036] Working principle: When using the improved ceramic filter protection device, the operator first puts the protective cover 1 on the outer peripheral side of the ceramic filter, then the ceramic filter fits the outer wall of the protective cover 1, and at the same time makes the bottom side of the protective cover 1 fit the circuit board, then the operator maintains the pressing strength of the protective cover 1 with one hand, and buckles the limit bar 33 out of the guide groove 4 with the fingers of the other hand, and then can synchronously pull the soft rod 32 through the limit bar 33, the operator's pulling force on the soft rod 32 offsets the friction between the soft rod 32 and the inner wall of the connecting hole 31, and the soft rod 32 moves upward, when the soft rod 32 and the inner wall of the connecting hole 31 conflict with each other, due to the mutual conflict between the soft rod 32 and the inner wall of the connecting hole 31, the soft rod 32 stops moving upward, and the operator continues to pull the limit bar 33 to tear off the connection between the connecting rope 34 and the soft rod 32, and then discards the limit rod and the connecting rope 34;

[0037] When the soft rod 32 moves upward, due to the expansion of the space in the connecting hole 31 at the bottom side of the soft rod 32, a negative pressure cavity is synchronously formed in the connecting hole 31 and the storage groove 21, and as the soft rod 32 moves upward, the negative pressure cavity in the connecting hole 31 and the storage groove 21 is synchronously strengthened. When the negative pressure cavity is formed in the storage groove 21, an upward pulling force can be applied to the soft ring 221, and as the soft rod 32 moves upward, the pulling force on the soft ring 221 is synchronously gradually increased, thereby offsetting the friction between the soft ring 221 and the inner wall of the storage groove opening, and finally pulling the soft ring 221 into the storage groove 21 to release the closed state of the storage groove 21 opening, and the adhesive in the storage groove 21 flows out from the opening of the storage groove 21 and flows into the gap between the open end of the protective cover 1 and the circuit board. After the operator maintains the pressing of the protective cover 1 for a period of time, the adhesive bonds the protective cover 1 to the circuit board.

[0038] It should be noted that, during the movement of the storage tank 21 into the storage tank 21, due to the mutual interference between the rubber rod 222 and the opening edge of the storage tank 21, the rubber ring automatically bends and deforms to automatically release the restraint limit state of the soft ring 221;

[0039] After the connection between the soft rod 32 and the soft rod 32 is disconnected, the soft rod 32 automatically moves down and resets due to the pull of the negative pressure cavity inside the connection hole 31 on the soft rod 32, thereby automatically reducing the negative pressure strength in the storage tank 21, thereby preventing the continuous formation of the negative pressure cavity in the storage tank 21 from affecting the outflow of the adhesive in the storage tank 21;

[0040] After the soft ring 221 is pulled into the storage groove 21, due to the mutual interference between the rubber rod 222 and the inner wall of the storage groove 21, a certain gap is used between the soft ring 221 and the inner wall of the storage groove 21, so as to prevent the adhesive in the storage groove 21 from flowing out of the storage groove 21, pushing the soft ring 221 to fit with the inner wall of the storage groove 21 again, and re-blocking the inner wall of the opening of the storage groove 21 to affect the outflow of the adhesive in the storage groove 21;

[0041] After the protective cover 1 is installed, the ceramic filter is stored in a closed space inside the protective cover 1, so as to prevent harmful gases or liquids from contacting the ceramic filter and causing damage to the ceramic filter.

[0042] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
