Description

Technical Field

[0001] The utility model relates to the technical field of filter equipment, in particular to a safe high-pressure filter structure. Background Art

[0002] A common problem with high-pressure filters in the prior art is that when the filter is opened for maintenance, the pump may be accidentally turned on due to an operating error, so that the liquid medicine may be sprayed from the opening of the filter onto the operator, causing a safety accident. Utility Model Content

[0003] In view of the shortcomings of the prior art, the main purpose of the utility model is to provide a safe high-pressure filter structure that can prevent the pump from being accidentally turned on when the cover is opened.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a safe high-pressure filter structure, including a main shell and a top cover, a connecting platform is arranged on the top of the main shell, and an external thread section is arranged on the connecting platform; an internal thread section is arranged on the inner wall of the top cover, and the top cover is threadedly connected to the connecting platform, an electromagnetic induction switch is arranged in the connecting platform on the main shell, and the electromagnetic induction switch is connected in series with the switch of the pump, a magnetic induction block is arranged at the bottom of the top cover, and an abutment sleeve is also arranged on the connecting platform, and a blocking column is extended on the outer wall of the top cover, and when the blocking column moves into the abutment sleeve as the top cover rotates, the magnetic induction block contacts and cooperates with the electromagnetic induction switch to achieve electrical conduction.

[0005] Preferably, the connecting platform is provided with a fixing groove for the electromagnetic induction switch to pass through.

[0006] Preferably, reinforcing ribs are provided on the side walls of the connecting platform.

[0007] Preferably, the retaining column and the top cover are integrally formed.

[0008] The utility model has the following advantages over the prior art: when the electromagnetic induction switch contacts the magnetic induction block, the electromagnetic induction switch is turned on; when the electromagnetic induction switch separates from the magnetic induction block, the electromagnetic induction switch is turned off; in addition, because the electromagnetic induction switch is connected in series with the switch of the pump, the problem of the pump being turned on by mistake due to operating errors when the filter is opened for maintenance in the prior art can be avoided by the utility model. The electromagnetic induction switch is turned off after the cover is opened, so the pump cannot be turned on. The electromagnetic induction switch and the magnetic induction block can be used to avoid the short circuit problem caused by the contact of the liquid medicine. The provision of a stop column and a matching abutment sleeve can achieve accurate positioning. Only when the top cover is rotated to this point can the electromagnetic induction switch and the magnetic induction block be matched accurately, avoiding the situation where the top cover cannot be rotated into place.

[0013] The utility model will be further described below in conjunction with the accompanying drawings.

[0014] like Figure 1 As shown, a safe high-pressure filter structure includes a main shell 1 and a top cover 2, wherein a connecting platform 3 is arranged on the top of the main shell 1, and an external thread section 4 is arranged on the connecting platform 3; an internal thread section 5 is arranged on the inner wall of the top cover 2, and the top cover 2 is threadedly connected to the connecting platform 3, an electromagnetic induction switch 6 is arranged in the connecting platform 3 on the main shell 1, and the electromagnetic induction switch 6 is connected in series with the switch of the pump, a magnetic induction block 7 is arranged at the bottom of the top cover 2, and an abutment sleeve 8 is also arranged on the connecting platform 3, and a stop column 9 is extended on the outer wall of the top cover 2, and when the stop column 9 moves into the abutment sleeve 8 as the top cover 2 rotates, the magnetic induction block 7 contacts and cooperates with the electromagnetic induction switch 6 to achieve electrical conduction.

[0015] The present scheme provides a safe high-pressure filter structure, wherein when the electromagnetic induction switch 6 contacts the magnetic induction block 7, the electromagnetic induction switch 6 is turned on, and when the electromagnetic induction switch 6 separates from the magnetic induction block 7, the electromagnetic induction switch 6 is turned off. In addition, since the electromagnetic induction switch 6 is connected in series with the switch of the pump, the problem of the pump being turned on by mistake due to an operational error when the filter is opened for maintenance in the prior art can be avoided by the present scheme. The electromagnetic induction switch 6 is turned off after the cover is opened, so the pump cannot be turned on. The electromagnetic induction switch 6 and the magnetic induction block 7 can avoid the short circuit problem caused by the contact of the liquid medicine. The provision of a stop column 9 and a matching abutment sleeve 8 can achieve accurate positioning. Only when the top cover 2 is rotated to this point, the electromagnetic induction switch 6 and the magnetic induction block 7 can be accurately matched, thereby avoiding the situation where the top cover 2 cannot be rotated into place.
