Description

Technical Field

[0001] The present invention relates to the technical field of helmet equipment, and in particular to a helmet with a haze protection function. Background Art

[0002] People wear helmets to protect their heads during cycling. When encountering foggy weather, they need to wear an anti-smog helmet. However, the steps for replacing the filter of existing helmets are cumbersome and labor-intensive, which is difficult to meet people's usage needs. Therefore, a helmet needs to be designed.

[0003] The patent application number CN212465092U discloses a high-protection helmet that prevents inhalation of haze. The helmet is first removed from the head, and then the triangular buckle block is detent to rotate with the spring at the bottom end as the axis, so that the top of the triangular buckle block is disengaged from the inside of the buckle groove, and then the top center of the haze protective cover is pulled upward to separate the haze protective cover from the front bottom center of the helmet. When the triangular buckle block rotates, it drives the spring at the bottom to rotate and deform, causing the spring to generate elastic force, and then the mask piece inside the haze protective cover is replaced. First, use external force to pull the mask piece out of the interior of the fixed interlayer, and then insert the new mask piece into the two ends of the limit clamp frame through the fixed interlayer, so that the haze protective cover is fixed to the front center bottom of the helmet. The helmet filters haze through the mask piece when in use, but the replacement steps are relatively cumbersome.

[0004] We have designed a helmet with smog protection function that has a simple filter replacement procedure, so as to overcome the cumbersome and labor-intensive process of replacing the mask sheet in existing helmets. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention provides a helmet with a haze protection function that has a simple filter replacement step, so as to overcome the disadvantage that the existing helmets have a relatively cumbersome step of replacing the mask piece during use.

[0006] To achieve the above objectives, the present invention is implemented through the following scheme: a helmet with a haze protection function, including a helmet, a goggles, a rotating shaft, a breathing port and a filter. The front and rear sides of the helmet are rotatably connected to the rotating shafts, the goggles are connected between the rotating shafts, the breathing port is connected to the left side of the lower part of the helmet, and a filter for filtering particulate matter is placed in the breathing port. It also includes a limiting mechanism and a pop-up mechanism. A limiting mechanism for clamping the filter is provided between the filter and the breathing port, and a pop-up mechanism for popping out the filter is provided in the breathing port.

[0007] As an improvement to the above scheme, the limiting mechanism includes a limiting rod and a first compression spring. The limiting rod is slidingly connected to the upper side of the breathing port. The limiting rod is engaged with the filter plate.

The guide rod is connected inside the breathing port, the support plate is slidably connected to the guide rod, and a tension spring is connected between the support plate and the breathing port, and the tension spring is wound around the guide rod.

[0009] As an improvement of the above scheme, it also includes a closing mechanism for closing the lower part of the helmet, the closing mechanism includes a protective cover, a spiral rod, a strap, a lock buckle, a mask cloth, a fixing buckle, a locking plate, a second compression spring and a torsion spring. The front side of the right side of the helmet is connected to the protective cover, the protective cover is rotatably connected to the spiral rod, a strap is wound around the spiral rod, the lower side of the strap is connected to the lock buckle, the spiral rod and the protective cover are connected, the torsion spring is wound around the spiral rod, the lower side of the helmet is connected to the mask cloth, the right rear side of the helmet is connected to the fixing buckle, the upper side of the fixing buckle is slidably connected to the locking plate, the locking plate and the fixing buckle are connected, the second compression spring is wound around the fixing buckle, and the lock buckle is manually pulled, the spiral rod rotates to release the strap, the torsion spring is twisted and deformed, and then people clamp the lock buckle on the fixing buckle. After the lock buckle contacts the locking plate, the locking plate moves forward, the second compression spring is compressed, and after the lock buckle moves away from the locking plate, the locking plate locks the lock buckle on the fixing buckle, and the released strap ties the mask cloth to people's necks.

[0010] As an improvement to the above scheme, a protective mechanism for limiting people's breathing range is also included. The protective mechanism includes a micro air pump, a catheter and an airbag. The micro air pump is installed on the lower left side of the helmet, and the airbag is connected to the right side of the breathing port. The micro air pump and the airbag are connected by a catheter. When the micro air pump is started, air flows into the airbag through the catheter, and the airbag expands to fit people's nose and chin.

[0011] As an improvement to the above solution, the airbag is arc-shaped and is used to fit people's nose and chin.

[0012] As an improvement to the above scheme, it also includes a fixing mechanism for clamping the goggles, the fixing mechanism includes a sliding sleeve, a locking rod, a sliding rod and a limit block, the sliding sleeve is threadedly connected to the spiral rod, the locking rod is connected to the upper side of the sliding sleeve, the sliding rod is slidably connected to the front right side of the helmet, the sliding rod is connected to the locking rod, the locking rod passes through the sliding rod, the front right side of the helmet is connected to the limit block, the locking rod is slidably connected to the limit block, a locking hole is opened on the right side of the front rotating shaft, and the locking rod engages with the locking hole after moving. The rotation of the spiral rod drives the sliding sleeve to move to the left, the locking rod and the sliding rod move to the left, and the locking rod engages with the locking hole after moving to the left.

[0013] As an improvement to the above scheme, it also includes an air intake mechanism for ventilation, which includes a fixed block, a connecting rope and a rubber plug. The front and rear sides of the lower part of the helmet are connected to the fixed blocks, and the connecting ropes are connected to the fixed blocks. The front and rear sides of the lower part of the helmet are provided with air intake holes, and rubber plugs are placed on the air intake holes. The connecting ropes are connected to the rubber plugs.

[0014] The advantages of the present invention are: 1. The present invention moves the limiting rod to the left away from the filter, so that the stretched tension spring is reset and drives the support plate and the filter to move upward. Then people can replace the filter, thereby achieving the effect of replacement and simple operation;

[0015] 2. People activate the micro air pump, allowing external air to flow into the airbag through the tube, causing the airbag to expand and come into contact with the nose and chin of the person, thereby achieving the expansion effect and allowing people to breathe through the breathing port, preventing people from inhaling smog;

[0016] 3. The rotation of the spiral rod drives the sliding sleeve to move to the left, causing the locking rod and the sliding rod to move to the left, thereby causing the locking rod to move to the left and engage with the locking hole to lock the goggles, thereby achieving a locking effect and preventing the goggles from rotating easily during riding.

DETAILED DESCRIPTION

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0035] Example 1

[0036] A helmet with haze protection function, now refer to Figure 1-Figure 3 , including a helmet 1, a goggles 2, a rotating shaft 21, a breathing port 3, a filter 4, a limiting mechanism 5 and a pop-up mechanism 6. The front and rear sides of the helmet 1 are rotatably connected with the rotating shaft 21, the goggles 2 are connected between the two rotating shafts 21, a breathing port 3 is welded on the left side of the lower part of the helmet 1, a filter 4 is placed in the breathing port 3, a limiting mechanism 5 is provided between the filter 4 and the breathing port 3, and a pop-up mechanism 6 is provided in the breathing port 3.

[0037] Reference Figure 1-Figure 5 The limiting mechanism 5 includes a limiting rod 51 and a first compression spring 52. The limiting rod 51 is slidably connected to the upper side of the breathing port 3. The limiting rod 51 is engaged with the filter 4. The first compression spring 52 is connected between the limiting rod 51 and the breathing port 3 through a hook. The first compression spring 52 is wound around the left side of the limiting rod 51.

[0038] Reference Figure 2 and Figure 6 The pop-up mechanism 6 includes a guide rod 61, a support plate 62 and a tension spring 63. The guide rod 61 is welded inside the breathing port 3. The support plate 62 is slidably connected to the guide rod 61. The support plate 62 is in contact with the filter 4. A tension spring 63 is connected between the support plate 62 and the breathing port 3, and the tension spring 63 is wound around the guide rod 61.

[0039] When people need to use the helmet 1, they can use this helmet with the function of protecting against smog. First, people can wear the helmet 1 on their heads. When encountering smog weather, people can manually rotate the goggles 2 counterclockwise, so that the rotating shaft 21 rotates counterclockwise. When the goggles 2 close the left side of the helmet 1, people can loosen the goggles 2. When the smog passes through the breathing port 3 and contacts the filter 4, the filter 4 filters the particulate matter in the smog, thereby achieving the effect of protecting against smog. When people do not need to wear the helmet 1, people can manually rotate the goggles 2 clockwise, so that the rotating shaft 21 rotates clockwise. When the goggles 2 are rotated clockwise to a suitable position, people can loosen the goggles 2, and then people can take off the helmet 1. When people need to replace the filter 4, people can manually Move the limit rod 51 to the left, so that the first compression spring 52 is stretched. When the limit rod 51 moves to the left away from the filter 4, the stretched tension spring 63 resets and drives the support plate 62 to move upward, so that the filter 4 moves upward. Then people take the filter 4 out of the breathing port 3. After taking it out, people insert a new filter 4 into the breathing port 3. When the new filter 4 contacts the support plate 62, the new filter 4 drives the support plate 62 to move downward, so that the tension spring 63 is stretched. When the new filter 4 moves downward to the appropriate position, people release the limit rod 51, so that the first compression spring 52 resets and drives the limit rod 51 to move to the right to jam the filter 4, thereby achieving the replacement effect. Then people can put the helmet 1 in place.

The locking plate 77 is slidably connected to the upper side of the fixing buckle 76. After the lock buckle 74 moves, it contacts the locking plate 77, and the locking plate 77 contacts the fixing buckle 76. A second compression spring 78 is connected between the locking plate 77 and the fixing buckle 76, and the second compression spring 78 is wound around the fixing buckle 76.

The air bag 83 is arc-shaped and is used to fit people's nose and chin. A catheter 82 is connected between the micro air pump 81 and the air bag 83.

[0043] Reference Figure 1 、 Figure 2 、 Figure 13 and Figure 14 , also includes a fixing mechanism 9, the fixing mechanism 9 includes a sliding sleeve 91, a locking rod 92, a sliding rod 93 and a limit block 94, the sliding sleeve 91 is threadedly connected to the spiral rod 72, and a locking rod 92 is welded on the upper side of the sliding sleeve 91. The front right side of the helmet 1 is slidingly connected to the sliding rod 93, the sliding rod 93 is connected to the locking rod 92, and the locking rod 92 passes through the sliding rod 93. The front right side of the helmet 1 is connected to the limit block 94, and the locking rod 92 is slidingly connected to the limit block 94. A locking hole 95 is opened on the right side of the front rotating shaft 21, and the locking rod 92 engages with the locking hole 95 after moving.

[0044] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 15 and Figure 16 , also includes an air intake mechanism 10, the air intake mechanism 10 includes a fixing block 101, a connecting rope 102 and a rubber plug 103, the fixing blocks 101 are welded on the front and rear sides of the lower part of the helmet 1, the two fixing blocks 101 are connected to the connecting rope 102, the front and rear sides of the lower part of the helmet 1 are opened with air intake holes 104, the two air intake holes 104 are placed with rubber plugs 103, and the connecting rope 102 is connected to the rubber plug 103.

[0045] When people put the helmet 1 on their heads, the protective cover 71 covers their necks. Then people manually pull the lock buckle 74, causing the spiral rod 72 to rotate and release the strap 73, thereby causing the torsion spring 79 to twist and deform. Then people buckle the lock buckle 74 on the fixing buckle 76. When the lock buckle 74 contacts the locking plate 77, the lock buckle 74 drives the locking plate 77 to move forward, and the second compression spring 78 is compressed. When people buckle the lock buckle 74 on the fixing buckle 76 away from the locking plate 77, the second compression spring 78 resets and drives the locking plate 77 to move backward and contact the fixing buckle 76, so that the released strap 73 ties the protective cover 71 to people's necks, thereby preventing haze from flowing through the lower side of the helmet 1. When people need to take off the helmet 1, they can manually move the locking plate 77 forward, so that the second compression spring 78 is compressed. When the locking plate 77 moves forward and away from the fixing buckle 76, people can remove the locking buckle 74 from the fixing buckle 76. When the locking buckle 74 is away from the fixing buckle 76, people can loosen the locking plate 77, so that the second compression spring 78 resets and drives the locking plate 77 to move backward. Then people loosen the strap 73, so that the torsion spring 79 resets and drives the spiral rod 72 to rotate in the opposite direction, so that the spiral rod 72 rotates in the opposite direction to wind up the strap 73, so that the locking buckle 74 moves to the front side of the helmet 1. Then people take off the helmet 1, so that the protective cover 71 is away from people's necks.

[0046] When people put the helmet 1 on their heads, they can start the micro air pump 81, so that the micro air pump 81 introduces external air into the air bag 83 through the conduit 82, causing the air bag 83 to expand and fit the nose and chin of the people, thereby achieving the expansion effect and allowing people to breathe through the breathing port 3. When people need to take off the helmet 1, they can turn off the micro air pump 81.

[0047] The rotation of the spiral rod 72 drives the sliding sleeve 91 to the left, thereby causing the locking rod 92 and the sliding rod 93 to move to the left. Then the locking rod 92 moves to the left until it engages with the locking hole 95, thereby achieving a locking effect to prevent the goggles 2 from easily rotating and affecting people's riding. The spiral rod 72 rotates in the opposite direction to drive the sliding sleeve 91 to the right, thereby causing the locking rod 92 and the sliding rod 93 to move to the right, causing the locking rod 92 to move to the right away from the locking hole 95.

[0048] When people need air to enter the helmet 1 while wearing it, they can pull out the rubber plug 103 from the air inlet 104 on the helmet 1, and then loosen the rubber plug 103 so that the connecting rope 102 pulls the rubber plug 103, and then air flows into the helmet 1 through the air inlet 104. When people do not need air intake, they can insert the rubber plug 103 into the air inlet 104.
