Description

car seat

The invention relates to a car seat, in particular to a car seat capable of filtering air.

As industrialization continues to intensify, the air quality in recent years has decreased year by year, causing many diseases and discomforts in people's respiratory system. Therefore, various air purification devices have been continuously developed on the market to reduce the burden on the respiratory system. Due to the large number of vehicles congested and exhausted on the roads driven by cars, it is often the worst air quality area except industrial areas. Although most cars are equipped with air conditioning systems with additional filters, these filters need to be disassembled to remove them when they are replaced. Therefore, ordinary consumers cannot replace the filters on their own. Loss of filtering function or accumulation of germs and dirt under use.

Therefore, it is an object of the present invention to provide a car seat with easy filter replacement.

Therefore, the automobile seat of the present invention includes a seat unit and an air purification unit. The seat unit has an accommodating space, at least one vent, and a filter. The air purification unit is disposed in the accommodation space of the seat unit, and includes a housing communicating with the at least one air vent and the filter opening, and at least one detachably disposed on the housing and facing the filter. Filter material, a pair of filter screens which are detachably disposed behind the filter material, and a fan disposed in the casing. The fan can be operated to guide the airflow, so that air passes through the filter screen and the at least one filter material in order to enter the casing through the filter port, and then is sent out from the at least one vent port.

The effect of the present invention is that the air filter unit is disposed on the seat unit, and the filter screen is detachably disposed behind the filter material corresponding to the filter port, so the user can directly remove the filter port. The filter screen and the at least one filter material have simple steps and are convenient for ordinary consumers to replace according to their needs.

1, FIG. 2, and FIG. 3, an embodiment of a car seat according to the present invention includes a seat unit 1 defining an accommodation space 10 and an accommodation space 10 disposed in the seat unit 1. Inside the air filtration unit 2. In the following description, the front and rear are defined by the orientation when the car seat is used.

The seat unit 1 includes a body 11 and a baffle 12 that is detachably fixed behind the seat body 11 in a locking manner and cooperates with the seat body 11 to define the accommodation space 10. The seat body 11 has two air vents 111 formed on opposite sides of the left and right and communicating with the accommodating space 10 (only one of them is shown in the figure due to the viewing angle). The baffle plate 12 has a filter opening 121 that faces rearward and communicates with the accommodating space 10.

The air purification unit 2 includes a housing 21, two filter materials 22 disposed on the housing 21 and facing the filter opening 121, and a pair of filter openings 121 disposed on the housing 21 and located behind the filter material 22. Filter 23 and a fan 24 disposed in the casing 21.

Referring to FIGS. 1, 3 and 4, the housing 21 has a positioning portion 211 defining a receiving slot 210, two guiding portions 212 connected to the left and right opposite sides of the positioning portion 211, and a positioning portion 211 respectively. A front cover portion 213 in front of the positioning portion 211 and a rear cover portion 214 disposed behind the positioning portion 211 and fixedly mated with the front cover portion 213. Each guide portion 212 has an air outlet groove 215 that communicates with the accommodation groove 210 and one of the air outlets 111 of the seat unit 1. In this embodiment, the exit of the air outlet groove 215 is up and down along the partition wall. Multiple openings are spaced in the direction, but not limited thereto. The front cover portion 213 and the rear cover portion 214 cooperate to define a communication space 216 that communicates with the accommodation groove 210 and the filter opening 121. The rear cover portion 214 defines an air intake groove 217 communicating with the communication space 216 and the filter opening 121 of the seat. The filter screen 23 is detachably clamped in the air intake groove 217 and is adjacent to the filter opening 121. The filter materials 22 are also installed in the air intake groove 217 in a snap manner and located in front of the filter screen 23. . The fan 24 is disposed on the front cover portion 213 and is located in the accommodation slot 210.

Referring to FIG. 1, FIG. 3, and FIG. 4, the fan 24 can be operated to suck air from the filter opening 121 and pass through the filter screen 23 and the filter materials 22 to enter the communication space 216 along the air inlet groove 217 after filtering. In the end, after entering the air outlet grooves 215 through the accommodating tank 210, the filtered air is sent out from the air vents 111 to release the filtered air to the vicinity of the car seat.

In this embodiment, the filter opening 121 is exposed above and behind the baffle plate 12 at a downwardly bent angle. Therefore, the filter opening 121 can be modified without appearing unexpectedly in appearance. Since the filter screen 23 is installed in the air inlet groove 217 and is adjacent to the filter port 121 in a snap-fit manner, and the filter port 121 is exposed on the baffle plate 12, the general consumer can directly use the special tool without special tools. The filter screen 23 and the filter materials 22 are removed for replacement to ensure that its filtering function is normal and to avoid long-term accumulation of germs and dirt. In addition, the air vents 111 are located on the left and right sides of the seat 11 and are close to the passengers so that the passengers can breathe the filtered air at the first time. It should be noted that the air vents 111 can be configured in addition to Outside the left and right sides of the seat body 11, air ducts (not shown in the figure) can also be connected to guide air to the target according to actual needs.

In summary, the air filter unit 2 is arranged on the seat unit 1 so that the user can remove and replace the filter net 23 and the filter materials 22 without using tools. Knowing the inconvenience of disassembling and replacing the filter 23, the purpose of the invention can be achieved.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
