Description

Technical Field

[0001] The utility model relates to the field of sealed and breathable containers, in particular to a barrel cover capable of air intake and exhaust. Background Art

[0002] When a traditional water storage barrel is connected to a water purifier and a water pump, the air pressure inside the barrel will change with the water level. In order to avoid pressure changes inside the barrel, which may lead to various functional abnormalities such as barrel rupture, traditional barrels usually reserve an open air hole to ensure the atmospheric pressure balance inside and outside the barrel.

[0003] However, the above traditional treatment method will make it easy for dust and mosquitoes to enter the open vent holes, which will cause the vent holes to be blocked or the water in the barrel to be contaminated. At the same time, the presence of the vent holes during the carrying and transportation process will also cause water leakage, requiring additional sealing covers or complicated operations.

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0026] like Figure 1 As shown, the utility model provides a barrel cover with air intake and exhaust, including a barrel cover body 1 and a barrel cover assembly. The inner side wall of the barrel cover body 1 is provided with a thread for fixing the barrel cover body 1. A fixing seat 2 is provided on the barrel cover body 1. The fixing seat 2 is cylindrical as a whole. A through-tube 3 is provided through the center of the fixing seat 2 and the through-tube 3 protrudes from the fixing seat 2. The barrel cover assembly includes an inlet and outlet elbow 10 adapted to the fixing seat 2. The barrel cover assembly is detachably mounted on the fixing seat 2 through the inlet and outlet elbow 10. An air intake and exhaust gap is formed between the inlet and outlet elbow 10 and the fixing seat 2, and air filter cotton 8 is provided between the inlet and outlet elbow 10 and the fixing seat 2. The air filter cotton 8 fits the inlet and outlet elbow 10 and the fixing seat 2. The air intake and exhaust gap can filter large particles of foreign matter in the air. The air filter cotton 8 has a high density characteristic and can filter tiny suspended dust in the outside air. The cooperation of the two can achieve a step-by-step filtering effect.

[0027] Preferably, the middle portion of the barrel cover body 1 is concave, and the fixing seat 2 is arranged in the center of the concave and forms an annular groove between the fixing seat 2 and the side wall of the concave.

[0028] Preferably, the fixing seat 2, the barrel cover body 1 and the through-tube 3 are designed as an integrated whole, and the lower end of the through-tube 3 is connected to a long tube extending to the bottom of the barrel body.

[0029] Preferably, the upper surface of the fixing seat 2 is provided with air intake and exhaust holes 4 , which are scattered and distributed around the through pipe 3 .

[0030] Preferably, a water extraction and injection interface is provided at the head end of the inlet and outlet elbow 10, the tail end of the inlet and outlet elbow 10 is sleeved on the surface of the fixed seat 2 and the upper end of the through pipe 3 is inserted into the interior of the inlet and outlet elbow 10, so as to ensure that the various components are tightly connected when pumping and injecting water.

[0031] Preferably, the edge of the tail end of the inlet and outlet elbow 10 is provided with an air intake gap 9 corresponding to the inlet and outlet holes 4, so that the inner wall of the inlet and outlet elbow 10 and the side wall of the fixing seat 2 form an air intake and exhaust gap.

[0032] like Figure 3 As shown, as a preference, when water is pumped out through the inlet and outlet elbow 10, the external air passes through the air intake gap 9, the air intake and exhaust gap, the air filter cotton 8, and the air intake and exhaust holes 4 in sequence into the barrel body connected to the barrel cover main body 1, achieving the effect of balancing the air pressure in the barrel.

[0033] Preferably, the barrel cover assembly further includes a fully sealed cover 7 for sealing the upper end opening of the through pipe 3 and the air inlet and outlet holes 4.

[0034] Preferably, the fully sealed cover 7 is installed on the side wall of the barrel cover body 1 through the connecting belt 6 and the anti-lost hanging ring 5. The fully sealed cover 7 is precisely matched with the fixing seat 2 and the through pipe 3, which can effectively ensure the sealing performance and facilitate installation and disassembly operations.

[0035] like Figure 2 As shown, preferably, a soft plug 11 is provided at the center of the fully sealed lid 7, which is adapted to fit the upper opening of the through-tube 3. The soft plug 11 and the fully sealed lid 7 are integrally designed and both are made of silicone. When the barrel needs to be transported or taken away, the inlet and outlet elbow 10 is removed, and the soft plug 11 of the fully sealed lid 7 is aligned with the upper opening of the through-tube 3. The fully sealed lid 7 is then replaced. At this point, the inlet and outlet holes 3 are sealed, thereby ensuring that the entire lid is airtight and preventing water leakage.

[0036] The operation mode of this utility model is as follows:

[0037] When it is necessary to connect a water pump or a water purifier to pump water, first fill or replace the annular air filter cotton 8 into the tail end of the inlet and outlet elbow 10, so that the air filter cotton 8 is completely fitted with the inlet and outlet elbow 10; then the inlet and outlet elbow 10 is sleeved on the fixing seat 2 of the barrel cover body 1, so that the upper end of the through pipe 3 is inserted into the inside of the inlet and outlet elbow 10. At this time, an air intake and exhaust gap will be formed between the inlet and outlet elbow 10 and the fixing seat 2, and the air filter cotton 8 will cover the top of the inlet and exhaust holes 4; finally, connect the water extraction interface of the inlet and outlet elbow 10 to the water pump to perform the pumping operation. During the pumping process, the water in the barrel will be successively pumped out through the long tube extending to the bottom of the barrel, the through pipe 3 and the inlet and outlet elbow 10, thereby forming a negative pressure in the barrel, such as Figure 3 As shown, at this time, the outside air enters through the air intake gap 9, passes through the air intake and exhaust gap, and after being filtered by the air filter cotton 8, enters the barrel through the air intake and exhaust holes 4, thereby balancing the air pressure inside the barrel.

[0038] When the barrel body needs to be taken out, the inlet and outlet elbow 10 is pulled out, the soft plug 11 of the full-sealing cover 7 is placed corresponding to the upper end opening of the through-tube 3, and the full-sealing cover 7 is covered. At this time, the inlet and outlet holes 3 are sealed, thereby ensuring the airtightness of the entire barrel body and preventing water leakage and seepage.

[0039] Although the embodiments of the present invention are described in the specification, these embodiments are only for reference and should not limit the scope of protection of the present invention. Various omissions, substitutions and changes within the scope of the present invention should be included in the scope of protection of the present invention.
