Referring to fig. 1 to 8, an enteral nutrition pump battery compartment according to an embodiment of the first aspect of the present invention includes a housing 100, a sealing ring 300, and an end cap 400, wherein the housing 100 is provided with a battery compartment 200, the housing 100 is provided with a first step 102 and a second step 101 around an edge of the battery compartment 200, the first step 102 surrounds the second step 101, and the first step 102 and the second step 101 form a sealing groove 130; the seal ring 300 is mounted in the seal groove 130; the end cover 400 is mounted on the battery compartment 200, the end cover 400 is provided with a first convex ring body 401, and the first convex ring body 401 abuts against the sealing ring 300.

According to the utility model discloses nutrition pump battery compartment in intestines has following beneficial effect at least: the moist gas enters the battery from the outside, and needs to pass through the first step 102, the sealing groove 130 and the second step 101, the first convex ring body 401 protrudes out of the end cover 400 and is abutted against the sealing ring 300, so that the moist gas cannot pass through a gap between the sealing ring 300 and the first convex ring body 401, and a waterproof effect is achieved; the first step 102 and the second step 101 cooperate to form a seal groove 130, which enables the seal ring 300 to be fixed.

Referring to fig. 1 to 4, in some embodiments of the present invention, in the first embodiment of the battery compartment 200, the first step 102 is flush with the second step 101, and the cross-sectional area of the first convex ring body 401 is much smaller than that of the sealing ring 300. The first step 102 is flush with the second step 101, so that the sealing ring 300 can be completely fixed, the sealing ring 300 cannot extend to two sides after being deformed, the acting force between the sealing ring 300 and the end cover 400 is improved, and the sealing performance is improved; the cross-sectional area of first bulge loop body 401 is far less than the cross-sectional area of sealing washer 300, and first bulge loop body 401 butt sealing washer 300 during the installation, sealing washer 300 and the 4 butt of first bulge loop body, and sealing washer 300 atress warp, and sealing washer 300 is embedded into completely to first bulge loop body 401, improves the structural seal degree.

The "cross-sectional area of the convex ring body and the cross-sectional area of the seal ring 300" is understood to mean the cross-sectional area of the convex ring body/the seal ring 300 at any position along the annular extending direction of the convex ring body/the seal ring 300, with the extending direction as a normal line and a plane perpendicular to the normal line as a section plane.

Referring to fig. 5 to 8, in some embodiments of the present invention, in the second embodiment of the battery compartment 200, the first step 102 is higher than the second step 101, the first convex ring body 401 is embedded in the sealing groove 130, the first convex ring body 401 is provided with the second convex ring body 402, the second convex ring body 402 abuts against the sealing ring 300, and the cross-sectional area of the second convex ring body 402 is far smaller than that of the sealing ring 300. The moist gas enters the battery from the outside, and needs to pass through the gap between the first step 102 and the end cover 400, the gap between the first step 102 and the first convex ring body 401, and the gap between the first convex ring body 401 and the sealing ring 300, because the first convex ring body 401 is abutted to the sealing ring 300, the second convex ring body 402 arranged on the first convex ring body 401 is completely embedded into the sealing ring 300, so that the second convex ring body 402 is tightly combined with the sealing ring 300, and the sealing purpose is achieved; compared with the first embodiment, the first step 102 is higher than the second step 101, so that the installation of the sealing ring 300 can be facilitated, and the required height of the sealing ring 300 is smaller.

In some embodiments of the present invention, a screw is further included, and the screw fixing end cap 400 is fixed to the housing 10 0. The screw serves to fix the end cap 400 to the case 100, prevent the end cap 400 from being detached, and improve sealability.

In some embodiments of the present invention, the housing 100 is provided with the escape groove 140, the end cap 400 is provided with the pin 410, and the pin 410 is inserted into the pin 410 groove. The end cap 400 is attached to the housing 100 at one end using pins 410 and is secured at the other end by screws so that the end cap 400 can be quickly fitted to the device.

In some embodiments of the present invention, first collar body 401 extends along pin 410. Since the first convex ring body 401 has an annular structure on the end cap 400, the continuity of the first convex ring body 401 is affected at the position of the pin 410 due to the protrusion of the pin 410, and the first convex ring body 401 extends on the pin 410, which is beneficial to sealing.

In some embodiments of the present invention, the sealing ring 300 is made of one of plastic, rubber, silica gel, metal-in-rubber, and metal-in-silica gel. These materials are all elastic materials, and the surface all has elasticity, is favorable to sealing washer 300 and first bulge loop body 401/second bulge loop body 402 to laminate completely, guarantees that the product is sealed.

In some embodiments of the present invention, the end cap 400 is provided with the positioning groove on the casing 100, and the end cap 400 is provided with the positioning block, the positioning groove cooperating with the positioning block. The positioning groove is matched with the positioning block, so that the end cover 400 is prevented from being dislocated with the shell 100 to influence installation.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
