Description

Technical Field

[0001] This application relates to the field of oxygen concentrator technology, for example to a handle for an oxygen concentrator and an oxygen concentrator. Background Technology

[0002] Currently, portable oxygen concentrators are portable medical devices primarily used to provide oxygen therapy. Their relatively small size makes them easy to carry. They use molecular sieve adsorption technology to separate oxygen from the air, providing a high concentration of oxygen. This oxygen is then delivered directly to the user through an oxygen tube and mask, making them quite convenient to use. However, the oxygen concentrators are relatively heavy, requiring both hands to hold them while moving them, which is cumbersome and results in a less than ideal user experience.

[0003] One related technology includes an oxygen concentrator comprising a body and a handle. The handle is located on top of the body, is fixedly connected to the body, and has a circular cross-section. The body has an air inlet and an air outlet. Users can easily lift the handle and move the oxygen concentrator with one hand, which is convenient and improves the user experience.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] When the user grips the handle, the cross-section of the handle differs significantly from the cross-section of a human hand when clenched into a fist, resulting in poor user comfort.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a handle for an oxygen concentrator and an oxygen concentrator, such that when a user holds the handle, the cross-section of the handle corresponds to the cross-section of a human hand clenching its fist, and the difference between the two cross-sections is reduced, thereby improving the user's grip comfort.

[0009] In some embodiments, the handle for an oxygen concentrator includes a handle body and a cover plate. The handle body has a first grip surface, a second grip surface, and a third grip surface that enclose a triangular shape; the cover plate abuts against the first grip surface and is connected to the handle body; wherein, a first arc surface is provided at the junction of the second grip surface and the third grip surface.

[0010] Optionally, the thickness of the cover plate is greater than or equal to one-twentieth of the thickness of the handle body, and less than or equal to one-eighth of the thickness of the handle body.

[0011] Optionally, the handle is provided with a connecting part that is perpendicular to the first gripping surface, and the connecting part is used to connect to an oxygen concentrator.

[0012] Optionally, the cover plate is a square ring-shaped structure, and the cover plate covers the outer periphery of the handle body and is connected to the handle body, and the connecting part abuts against the inner sidewall of the cover plate.

[0013] Optionally, the area of ​​the second gripping surface is larger than the area of ​​the third gripping surface.

[0014] Optionally, the width of the cover plate is the same as the width of the handle.

[0015] Optionally, the body and / or cover plate may be made of plastic.

[0016] In some embodiments, the oxygen concentrator includes a handle for the oxygen concentrator as described in the above embodiments.

[0017] Optionally, the oxygen concentrator also includes a display. The display is connected to the connector.

[0018] Optionally, multiple buttons are provided on one side of the display.

[0019] The handle and oxygen concentrator for an oxygen concentrator provided in this disclosure can achieve the following technical effects:

[0020] Because the first, second, and third grip surfaces of the handle body form a near-triangular shape, corresponding to the cross-section of a clenched fist, the handle body better conforms to the user's hand, and the difference between the two cross-sections is relatively small, thus improving user grip comfort. Furthermore, the risk of the handle body and the user's hand slipping relative to each other is relatively low when the user grips the first, second, and third grip surfaces. The cover plate abuts against the first grip surface, further enhancing the overall integrity of the handle.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0039] Combination Figure 1-3 As shown, this embodiment of the present disclosure provides a handle for an oxygen concentrator, including: a handle body 100 and a cover plate 200. The handle body 100 is provided with a first grip surface 101, a second grip surface 102, and a third grip surface 103 that enclose a triangular shape; the cover plate 200 abuts against the first grip surface 101 and is connected to the handle body 100; wherein, a first arc surface 104 is provided at the connection between the second grip surface 102 and the third grip surface 103.

[0040] The handle for an oxygen concentrator provided in this embodiment of the invention, with its first gripping surface 101, second gripping surface 102, and third gripping surface 103 forming a near-triangular shape corresponding to the cross-section of a clenched fist, allows the handle 100 to better fit the user's hand, and the difference between the two cross-sections is relatively small, thereby improving user grip comfort. Furthermore, the risk of relative slippage between the handle 100 and the user's hand is relatively low when the user grips the first gripping surface 101, second gripping surface 102, and third gripping surface 103. The cover plate 200 abuts against the first gripping surface 101, further enhancing the overall integrity of the handle.

[0041] Understandably, the connection between the second grip surface 102 and the third grip surface 103 is provided with a first arc surface 104, which makes the connection between the second grip surface 102 and the third grip surface 103 relatively smooth, and the user's comfort level is relatively high when holding the handle body 100.

[0042] Optionally, the thickness of the cover plate 200 is greater than or equal to one-twentieth of the thickness of the handle body 100, and less than or equal to one-eighth of the thickness of the handle body 100. When the thickness of the cover plate 200 is less than one-twentieth of the thickness of the handle body 100, the cover plate 200 is too thin. Since the cover plate 200 comes into direct contact with the user's hand while holding the handle body 100, the risk of breakage is high. When the thickness of the cover plate 200 is greater than one-eighth of the thickness of the handle body 100, the cover plate 200 is too thick. When the user holds the handle body 100, the excessively thick cover plate 200 results in an excessively large grip size, affecting the user's grip feel. Therefore, it is reasonable for the thickness of the cover plate 200 to be greater than or equal to one-twentieth of the thickness of the handle body 100 and less than or equal to one-eighth of the thickness of the handle body 100. This reduces the risk of the cover plate 200 breaking during the user's grip on the handle body 100 and also reduces the impact of the cover plate 200 on the user's grip feel.

[0043] Understandably, the thickness of the handle body 100 refers to the distance between the connection point of the second grip surface 102 and the third grip surface 103 and the first grip surface 101, that is, the maximum distance between the first arc surface 104 and the first grip surface 101; the thickness of the cover plate 200 refers to the distance between the side of the cover plate 200 that abuts against the handle body 100 and the side of the cover plate 200 that faces away from the handle body 100.

[0044] Alternatively, the thickness of the cover plate 200 is equal to one-twelfth the thickness of the handle 100. This reduces the risk of the cover plate 200 breaking during the user's grip on the handle 100, and also reduces the impact of the cover plate 200 on the user's grip feel.

[0045] Combination Figure 4As shown, optionally, the handle 100 is provided with a connecting portion 110 perpendicular to the first grip surface 101, and the connecting portion 110 is used to connect to the oxygen concentrator. Thus, by connecting to the oxygen concentrator through the connecting portion 110, and with the connecting portion 110 perpendicular to the first grip surface 101, the distance between the handle 100 and the oxygen concentrator is relatively large. This makes it easier for the user to reach between the handle 100 and the oxygen concentrator to lift them, resulting in a better user experience.

[0046] Optionally, the connecting part 110 is a connecting rod 111. There are two connecting rods 111, which are located on two opposite sides of the first grip surface 101, and the connecting rods 111 are connected to the oxygen concentrator. In this way, the handle body 100 and the oxygen concentrator are connected by two connecting rods 111, which provides more connection points, higher connection strength, and better connection stability.

[0047] Optionally, the thickness of the end of the connecting rod 111 facing away from the first gripping surface 101 is less than the thickness of the end of the connecting rod 111 facing the first gripping surface 101. In this way, by connecting the oxygen concentrator through the end of the connecting rod 111 with the smaller thickness, the height of the connecting rod 111 protruding from the oxygen concentrator is reduced, the risk of the connecting rod 111 being bumped or scratched is reduced, and the user experience is improved.

[0048] Combination Figure 4 As shown, optionally, the connecting rod 111 is provided with a plug-in protrusion 112, which is plugged into the oxygen concentrator. In this way, by plugging into or removing the connecting rod 111 from the oxygen concentrator through the plug-in protrusion 112, it is convenient to install, fix or remove the connecting rod 111, so as to replace and maintain the handle 100.

[0049] Optionally, each connecting rod 111 is provided with multiple insertion protrusions 112. In this way, by inserting into the oxygen concentrator through multiple insertion protrusions 112, there are relatively more connection points, the connection strength is relatively higher, and the connection stability is better.

[0050] Specifically, each connecting rod 111 is provided with three insertion protrusions 112. In this way, each connecting rod 111 is inserted into the oxygen concentrator through three insertion protrusions 112, resulting in a relatively large number of connection points, relatively high connection strength, and better connection stability.

[0051] Understandably, the insertion protrusion 112 and the connecting rod 111 are integrally formed, which makes the connection between the insertion protrusion 112 and the connecting rod 111 relatively strong.

[0052] Optionally, the cover plate 200 has a square-like annular plate structure, and the cover plate 200 covers the outer periphery of the handle body 100 and is connected to the handle body 100, with the connecting part 110 abutting against the inner sidewall of the cover plate 200. In this case, when the handle body 100 is connected to the oxygen concentrator, a gap will remain at the connection point. The square-like annular cover plate 200 can cover the handle body 100 inside the cover plate 200, thereby concealing the gap at the connection point and improving the overall integrity of the oxygen concentrator and the handle body 100.

[0053] Specifically, the cover plate 200 is fixedly connected to the handle body 100. This results in a relatively high connection strength and better connection stability.

[0054] Specifically, the connecting rod 111 is fixedly connected to the inner wall of the cover plate 200. In this way, the connection area between the connecting rod 111 and the cover plate 200 is relatively large, the connection strength is relatively high, and the connection stability is better.

[0055] Optionally, the width of the cover plate 200 is the same as the width of the handlebar 100. In this way, the cover plate 200 can better cover the handlebar 100.

[0056] Specifically, the width of the cover plate 200 is the same as the width of the first grip surface 101. In this way, the cover plate 200 can better cover the handle body 100.

[0057] Optionally, the area of ​​the second grip surface 102 is larger than the area of ​​the third grip surface 103. This results in a relatively larger area for the second grip surface 102. Since the combined length of the middle and distal phalanges is relatively long, when the user grips the handle 100, the second grip surface 102 conforms to the finger portions of the middle and distal phalanges, while the third grip surface 103 conforms to the finger portion of the proximal phalanx. This provides a better fit and improves user grip comfort.

[0058] Specifically, the distance between the first curved surface 104 and the first grip surface 101 and the second grip surface 102 is greater than the distance between the first curved surface 104 and the first grip surface 101 and the third grip surface 103. This allows the second grip surface 102 and the third grip surface 103 to better fit the user's hand, thereby improving the user's grip comfort.

[0059] Optionally, the second grip surface 102 and / or the third grip surface 103 are matte surfaces. When the second grip surface 102 is matte, the frictional force experienced by the user gripping it is relatively high, reducing the risk of the handlebar 100 slipping relative to the user's hand. Similarly, when the third grip surface 103 is matte, the frictional force experienced by the user gripping it is relatively high, further reducing the risk of the handlebar 100 slipping relative to the user's hand. With both the second and third grip surfaces 102 and 103 being matte surfaces, the user experiences relatively high frictional force when gripping both surfaces, and the surface area is larger, further reducing the risk of the handlebar 100 slipping relative to the user's hand.

[0060] Understandably, smaller protrusions or grooves are provided on the second gripping surface 102 and / or the third gripping surface 103 to make the surface rougher and increase friction.

[0061] Optionally, the outer surface of the cover plate 200 is frosted. In this way, when the user holds the handle 100 and the cover plate 200, the friction between the cover plate 200 and the user's hand is relatively large, reducing the risk of the cover plate 200 slipping relative to the user's hand.

[0062] In one embodiment, both the handle 100 and / or the cover plate 200 are made of plastic. This makes the handle 100 relatively lightweight, reducing the overall weight of the oxygen concentrator. Similarly, making the cover plate 200 relatively lightweight further reduces the overall weight of the oxygen concentrator. Furthermore, the relatively low thermal conductivity of plastic makes it more comfortable for the user to hold.

[0063] Optionally, the handle body 100 and / or the cover plate 200 are both made of ABS plastic (Acrylonitrile Butadiene Styrene plastic). Thus, the handle body 100 and the cover plate 200, both made of ABS plastic, have good corrosion resistance and high-temperature resistance.

[0064] Understandably, the connecting rod 111 is also made of ABS plastic, and the connecting rod 111 and the handle body 100 are integrally molded.

[0065] In another embodiment, the body 100 is made of plastic and the cover plate 200 is made of rubber.

[0066] Combination Figure 5As shown, optionally, a heating element 300 is provided inside the handlebar 100. In this way, heating is achieved through the heating element 300, and heat is then conducted to the handlebar 100 and the cover plate 200, increasing the temperature of the handlebar 100 and the cover plate 200. This improves the user's comfort when holding the handlebar 100 and the cover plate 200 at lower temperatures.

[0067] Optionally, the heating element 300 is a heating wire 310. Heating is achieved through the heating wire 310, which then conducts heat to the handlebar 100 and the cover plate 200, increasing their temperature. This improves user comfort when holding the handlebar 100 and cover plate 200 at lower temperatures.

[0068] Understandably, the oxygen concentrator is equipped with a battery, which is electrically connected to the heating wire 310 and supplies power to the heating wire 310.

[0069] Understandably, the heating element 300 can also be a conventional heating component such as an electric heating rod or an electric heating plate, in order to increase the temperature of the handle 100 and the cover plate 200.

[0070] In some embodiments, the oxygen concentrator includes: a handle for the oxygen concentrator as described in the above embodiments.

[0071] The oxygen concentrator provided in this embodiment includes a handle as described in the above embodiment. The first gripping surface 101, the second gripping surface 102, and the third gripping surface 103 of the handle 100 form a near-triangular shape, corresponding to the cross-section of a clenched fist. This allows the handle 100 to better fit the user's hand, and the difference between the two cross-sections is relatively small, thereby improving user comfort. Furthermore, the risk of relative slippage between the handle 100 and the user's hand is relatively low when the user grips the first gripping surface 101, the second gripping surface 102, and the third gripping surface 103. The cover plate 200 abuts against the first gripping surface 101, improving the overall integrity of the handle.

[0072] Combination Figure 6 As shown, optionally, the oxygen concentrator also includes a display 400. The display 400 is connected to the connection unit 110. In this way, the operating parameters of the oxygen concentrator can be displayed on the display 400, and the functions of the oxygen concentrator can also be adjusted via the touch screen.

[0073] Optionally, the display 400 protrudes from one side of the connector 110. In this way, the protruding display 400 is not obstructed by the connector 110 and the handle 100, ensuring that the user can see the information on the display 400 more intuitively, resulting in a better user experience.

[0074] Optionally, a gripping gap 401 is provided between the display 400 and the handle 100. In this way, the user's hand can pass through the gripping gap 401 between the display 400 and the handle 100 to grip the handle 100, making the operation more convenient and providing a better user experience.

[0075] Optionally, a plurality of buttons 500 are provided on one side of the display 400. In this way, the user can press the buttons 500 to adjust the corresponding functions of the oxygen concentrator.

[0076] Optionally, multiple buttons 500 can be connected sequentially. This arrangement of multiple buttons 500 in sequence is neater and improves the overall appearance of the oxygen concentrator.

[0077] Optionally, the button 500 has six buttons. In this way, different functions of the oxygen concentrator can be controlled by the six buttons 500, making it easy to adjust the operating status of the oxygen concentrator.

[0078] Optionally, button 500 is made of ABS plastic (Acrylonitrile Butadiene Styrene plastic). In this way, button 500 made of ABS plastic has good corrosion resistance and high-temperature resistance.

[0079] Optionally, multiple buttons 500 abut against the inner wall of the cover plate 200, thereby improving the overall integrity of the oxygen concentrator.

[0080] Optionally, two of the multiple buttons 500 abut against the two connecting parts 110 respectively. In this way, the multiple buttons 500 are located between the two connecting parts 110 and arranged in sequence, improving the overall integrity of the oxygen concentrator.

[0081] Specifically, two of the multiple buttons 500 abut against the two connecting rods 111 respectively. In this way, the multiple buttons 500 are located between the two connecting rods 111 and arranged in sequence, improving the overall integrity of the oxygen concentrator.
