Abstract
Description
Technical Field
[0001] The present invention belongs to the field of air purification, and in particular, to an air purifier suitable for aviation devices. Background Art
[0002] The inventor of the present invention is a person who is used to wearing a mask. The inventor has made a variety of air purification devices, and these air purification devices all rely on electric drive. For example, a fan squeezes air into a cavity, and there is an air filter element in the cavity. Then, the air is discharged outwards from the air filter element, thereby playing a role in air purification.
[0003] However, when the inventor planned to take a plane and learned during the travel preparation stage that on a certain plane in a specific area, passengers are not allowed to use any electrical appliances. That is to say, all the air purifiers previously made by the inventor cannot be used because the previously made air purifiers all rely on electric energy.
[0004] The inventor searched for non-electric air purifiers on major e-commerce platforms so that they can be used on the plane, but no relevant products were found. Therefore, the inventor decided to invent a non-electric air purifier.
[0005] The inventor has manufactured the air purifier and provided physical photos as evidence. Summary of the Invention
[0006] In order to overcome the deficiencies of the prior art, the present invention discloses an air purifier, which includes a foot-operated air pump and a hose. The characteristics are as follows: it further includes an air filter box, and the air filter box is a hollow shell structure. The air filter box includes a shell, and a filter element hole is opened on one side of the shell. An air filter element is fixedly connected to the inner wall of the shell, and the periphery of the filter element hole and the periphery of the air filter element are airtight. The shell is also provided with a joint for gas to enter. One end of the hose is connected to the foot-operated air pump, and the other end of the hose is connected to the joint. When the foot-operated air pump is compressed, air enters the hose from the foot-operated air pump, then enters the air filter box from the joint, and after being filtered by the air filter element, the filtered air is blown out from the filter element.
[0007] The number of the foot-operated air pumps is 2, and these 2 foot-operated air pumps use a tee structure to blow air into the air filter box, and a one-way valve is provided inside the hose connected to the foot-operated air pump, so that air can only flow from the foot-operated air pump to the air filter box direction.
[0008] The present invention does not use electricity and can purify air well, and can meet the requirements of aviation. Brief Description of the Drawings

[0016] For clearly illustrating the present technical solution, please refer to the attached Figure 1 and the attached Figure 3 、the attached Figure 4 、the attached Figure 5 、the attached Figure 6 . The inventor purchased an INTEX 69611 foot-operated air pump 5, and this foot-operated air pump 5 is used to inflate balloons and inflatable beds. Of course, the foot-operated air pump 5 belongs to the prior art.
[0017] The inventor also used a cardboard box as the housing 1. A filter element hole was dug on one side of the cardboard box, and then an air filter element 2 slightly larger than the filter element hole in size was used to cover and bond the filter element hole. The filter element hole is square with a side length of 13 cm, and the air filter element 2 is also square with a side length of 14 cm. It is appropriate that the length of each side of the air filter element 2 is 1 cm larger than the length of the corresponding side of the filter element hole. Of course, the periphery of the filter element hole and the periphery of the air filter element 2 are airtight connected. Regarding the airtight connection mentioned here, two points should be noted: 1. It is the periphery. There must be gas discharge from this device, but air leakage should be ensured not to occur at the periphery, and the bonding should be reliable.
[0018] The inventor also found a kind of joint 3, and the trade name of this joint 3 is the external thread joint 3 of the water tank. The inventor made a hole on one side of the cardboard box, that is, the housing 1, installed this joint 3, then connected the foot-operated air pump 5 and the joint 3 with a hose 4, and then glued the cardboard box all over with adhesive tape, which is both airtight and strong. Thus, this invention was completed. The glue used by the inventor to bond the air filter element 2 and the cardboard box is Kraft brand sealant, and this brand of glue includes food-grade glue, which is safe, odorless, and non-toxic.
[0019] An air purifier includes a foot-operated inflator pump 5 and a hose 4. Those skilled in the art should be aware that the hose 4 should be adapted to, or matched with, the foot-operated inflator pump 5. It also includes an air filter box which is of a hollow structure. The air filter box includes a housing 1, that is, the cardboard box mentioned in the embodiment. A filter element hole is provided on one side of the housing 1, and the gas discharged from the air filter element 2 is discharged through the filter element hole.
[0020] The air filter element 2 is fixedly connected to the inner wall of the housing 1. Here, the fixed connection is preferably by bonding. The periphery of the filter element hole and the periphery of the air filter element 2 are airtight. The housing 1 is also provided with a connector 3 for gas to enter. This connector 3 is the water tank external thread connector 3 mentioned in the embodiment. One end of the hose 4 is connected to the foot-operated inflator pump 5, and the other end of the hose 4 is connected to the connector 3. Those skilled in the art should be aware that for the connection of the hose 4, airtightness should be ensured, and a pipe clamp or glue can be used to ensure airtightness. When the foot-operated inflator pump 5 is compressed, air enters the hose 4 from the foot-operated inflator pump 5, then enters the air filter box through the connector 3, and after being filtered by the air filter element 2, the filtered air is blown out from the filter element.
[0021] When in use, the foot-operated inflator pump 5 is repeatedly compressed. In fact, it can be foot-operated or hand-pressed. The gas is filtered and blown out from the filter element. For example, when one has to take off the mask, the housing 1 can be placed upright on the table with the filter element hole facing the user's face, and at the same time, the foot-operated inflator pump 5 is repeatedly compressed. The air is filtered and then blown towards the person's face, providing a relatively clean air area for the face. Those skilled in the art should be aware that in order to obtain better effects, after continuously filtering the air for several minutes, the mask can be taken off, and the air quality in the facial area can be better guaranteed. The present invention achieves the effect of air purification without using electricity.
[0022] To illustrate the inventiveness of the present invention, the applicant gives a technical explanation: The "Patent Examination Guidelines" states: "An invention overcomes a technical prejudice" as follows: "A technical prejudice refers to a generally existing, factually deviated understanding of a technical problem by technicians in a certain technical field within a certain period of time. It guides people not to consider other possibilities and hinders people's research and development in this technical field. If an invention overcomes this technical prejudice, adopts a technical means that people have discarded due to the technical prejudice, and thus solves the technical problem, then this invention has prominent substantive features and significant progress and has inventiveness." Prior art air purifiers with filter cartridges are all powered by electricity, which discourages people from considering other possibilities and hinders research and development in this technical field. Consequently, no air purifiers with air filter cartridges 2 that do not require electricity exist on the market. The inventor encountered this technical problem while traveling on an airplane and creatively employed a technical approach that was often discarded due to technical bias, thereby resolving the problem. Therefore, this invention possesses outstanding substantive features and represents a significant advancement, thus possessing inventiveness.
[0023] Example 2: See attached Figure 2 Embodiment 1 presents a technical problem: because the foot-operated air pump 5 requires repeated compression, there are stages where the air is not squeezed into the air filter cartridge. While Embodiment 1 already provides good results, for even greater effectiveness, two foot-operated air pumps 5 can be used. This allows both feet to operate the foot-operated air pumps 5, with one foot operating each. Furthermore, these two foot-operated air pumps 5 utilize a three-way connection to pump air into the air filter cartridge. For example, by using a three-way connector 6 to connect the two foot-operated air pumps 5 and the air filter cartridge, the two feet move in opposite directions, just like walking. This allows the present invention to continuously supply clean air, further improving the user's experience. Furthermore, to ensure air flow, a one-way valve 7 is installed within the hose 4 connected to the foot-operated air pump 5, ensuring that air can only flow from the foot-operated air pump 5 to the air filter cartridge. The one-way valve 7 is readily available and is known in the art. Alternatively, the one-way valve 7 can be located within the hose and fixedly connected to the hose 4. There are two foot-operated air pumps, and these two foot-operated air pumps use a three-way structure to blow air into the air filter box. In other words, one end of the hose is connected to the connector 3, and the other end of the hose is connected to the three-way component, that is, the three-way connector. The other two air flow ports of the three-way connector are connected to two hoses respectively. These two hoses are respectively connected to the foot-operated air pump, and a one-way valve is provided inside the hose connected to the foot-operated air pump, so that air can only flow from the foot-operated air pump to the air filter box.
[0024] The invention does not use electricity and has a very simple structure, so simple that even primary school students can understand and manufacture it. It can also continuously output clean air and meet aviation requirements.
[0025] The present invention provides photos of the actual object. These photos are only for the examiner's reference to prove that this is a valuable invention and a normal invention. The presence or absence of photos does not affect the scope of protection of the present invention. It is acceptable even if the photos are deleted.
