Technical Field
[0001] The utility model relates to the technical field of household appliances, and more specifically to a handle assembly on a household appliance such as a humidifier. Background Art
[0002] Various household appliances, such as heaters, coolers or humidifiers, have handles for users to move them. For example, a humidifier can satisfy users' free adjustment of air humidity. In other words, with the improvement of living standards, people have higher and higher requirements for indoor air quality and comfort, requiring not only indoor air temperature to be within a suitable range, but also indoor air humidity to be within a suitable range. Therefore, a humidifier can adjust the humidity of indoor air to meet users' needs for indoor air comfort.
[0003] Although such household appliances in the prior art also have handles, most of the handles are integrated structures, which have the problems of complex structure, insufficient strength and high cost. In addition, when the handle of the prior art is at any angle, the handle will drop quickly / slowly, causing the handle to fall and cannot be lifted up for use in time.
[0004] Therefore, the industry needs to provide an improved handle assembly to overcome the above-mentioned defects of the prior art. Utility Model Content
[0005] The purpose of the utility model is to solve the above problem and provide a handle assembly.
[0006] In order to meet the purpose of the utility model, the utility model adopts the following technical solutions:
[0007] A handle assembly comprises a box body and a handle, wherein the box body has two side walls arranged opposite to each other, and each of the side walls has an axial hole; the handle has two pivot arms arranged opposite to each other, and the two pivot arms are located between the two side walls, and each of the pivot arms is provided with a rotating shaft; the rotating shafts are pivoted in corresponding axial holes, and an arc-shaped damping portion is formed on the circumferential surface of each rotating shaft, which is interference-fitted with the inner wall of the axial hole.
[0008] Preferably, an arc-shaped damping groove is formed in each of the axial holes and extends radially outward and is engaged with the corresponding arc-shaped damping portion.
[0009] Preferably, a notch extending radially outward is formed in each of the axial holes; a limiting protrusion extending radially outward is also formed on the circumferential surface of each of the rotating shafts; each of the limiting protrusions passes through the corresponding notch and is configured to limit the edge of the corresponding axial hole between the limiting protrusion and the corresponding pivot arm when it is misaligned relative to the corresponding notch.
[0010] Preferably, the arc-shaped damping portion of each rotating shaft is distributed on the circumferential surface of the rotating shaft in radially opposite relation to the limiting protrusion.
[0011] Preferably, the interference fit between the arc-shaped damping portion of each rotating shaft and the inner wall of the shaft hole is 0.1-0.3 mm.
[0012] Preferably, the handle further comprises a holding arm connecting the two pivot arms.
[0013] Preferably, the notch of each of the axial holes forms an acute angle with the top surface of the side wall along a direction in which the notch extends radially outward of the axial hole.
[0014] Preferably, the limiting protrusion of each of the rotating shafts extends along the length direction of the corresponding pivot arm.
[0015] Preferably, a stopper is protruded from one end of each side wall close to the corresponding pivot arm and is used to prevent the pivot arm from excessively rotating.
[0016] Preferably, a placing platform corresponding to the stopper is protruded from one end of each of the side walls close to the corresponding pivot arm, and is configured to place the corresponding pivot arm thereon.
[0017] Compared with the prior art, the beneficial technical effects of the utility model are as follows:
[0018] In the handle assembly provided by the utility model, since an axial hole is provided on the side wall of the box body; a rotating shaft that rotates with the axial hole is provided on the pivot arm of the handle; and since an arc-shaped damping portion that interference fits with the inner wall of the axial hole is formed on the circumferential surface of each rotating shaft, the handle can produce a damping effect through the interference (friction) fit between the arc-shaped damping portion and the inner wall of the axial hole. For example, the user can operate the handle and let it stay in any suitable position, so that the handle can be fixed at a certain angle, thereby improving customer experience and increasing the grade of the product; unlike the prior art, the handle will slowly or quickly tilt and rotate and finally be in a horizontal state, causing the user to lift the handle from the horizontal position to the required position again.

[0029] In one embodiment of the present invention, reference Figure 1-3c, a handle assembly 100 is provided, comprising a box body 10 and a handle 20.
[0030] The handle 20 is rotatably disposed on the housing 10. The housing 10 may be any suitable housing of a household appliance, such as a housing of a humidifier, a heater or a cooler. The user may lift the entire household appliance and move the appliance by the handle 10, thereby achieving portability of the appliance. The housing 10 may be made of, for example, a plastic material that is harmless to the human body, environmentally friendly and durable.
[0031] Correspondingly, the handle 20 can also be made of similar materials to achieve similar technical effects. Of course, since the handle 20 is often lifted, it needs to have sufficient structural strength. Therefore, the handle 20 can be designed to be made of a metal material with sufficient strength. At the same time, considering the lightness of the entire appliance, a lightweight aluminum alloy material can be used to process the handle 20.
[0032] In one embodiment, the box body 10 has two side walls 12 arranged opposite to each other, each of the side walls 12 has an axis hole 122; the handle 20 has two pivot arms 22 arranged opposite to each other, the two pivot arms 22 are located between the two side walls 12, each of the pivot arms 22 is provided with a rotating shaft 222; the rotating shaft 222 is pivoted in the corresponding axis hole 122. In particular, an arc-shaped damping portion 2222 is formed on the circumferential surface of each rotating shaft 222, which is interference-fitted with the inner wall of the axis hole 122.
[0033] Here, this interference fit or tight friction fit can bring obvious technical effects. Specifically, through the interference (friction) fit between the arc-shaped damping portion 2222 and the inner wall of the shaft hole 122, the handle 20 can produce a damping effect, so that the user can freely manipulate the handle 20 and let it stay at any suitable angle and height, so that the handle 20 can be fixed at a specific angle by the user. This not only improves the customer experience, but also increases the product grade. In contrast, in the prior art, the handle will slowly or quickly tilt and rotate and finally be in a horizontal state, causing the user to lift the handle from the horizontal position to the desired position again, and the handle of the prior art does not have any damping feeling, and the user experience is poor.
[0034] In this embodiment, the size and shape of the arc-shaped damping portion 2222 can be appropriately adjusted according to specific requirements and the correspondence with the inner wall of the shaft hole 122. The present invention does not limit this.
[0035] In addition, due to the interference (friction) fit between the arc-shaped damping portion 2222 and the inner wall of the shaft hole 122, and the frequent relative rotation of the two, there is a possibility of mutual wear between the two. Long-term use will cause serious wear of the two, resulting in gaps and weakening the damping feeling. For this reason, a wear-resistant layer can be added to the arc-shaped damping portion 2222 and / or the inner wall to reduce long-term wear and extend the service life.
[0036] In one embodiment, an arc-shaped damping groove 1222 extending radially outward and engaging with the corresponding arc-shaped damping portion 2222 may be formed in each of the shaft holes 122. Thus, the components that produce interference or friction fit are the arc-shaped damping portion 2222 and the arc-shaped damping groove 1222. Since the arc-shaped damping groove 1222 has a larger area than the inner wall of the shaft hole 122, the contact area of the interference fit between the arc-shaped damping portion 2222 and the arc-shaped damping groove 1222 is ensured, and the larger contact area can enhance the damping strength when the two rotate together, so that the user can feel a more obvious damping feeling.
[0037] According to an embodiment of the utility model, a notch 1224 extending radially outward is further formed in each of the shaft holes 122; a limiting protrusion 2224 extending radially outward is further formed on the circumferential surface of each of the rotating shafts 222; each of the limiting protrusions 2224 passes through the corresponding notch 1224, and is configured to limit the edge of the corresponding shaft hole 122 between the limiting protrusion 2224 and the corresponding pivot arm 22 when the limiting protrusion 2224 is relatively misaligned with the corresponding notch 1224. Through this setting, the handle 20 can be quickly inserted into the corresponding position in the box body 10, and by making the limiting protrusion 2224 of the handle 20 and the corresponding notch 1224 misaligned with each other, it can be ensured that the handle 20 will not fall off the box body 10. Thus, the handle 20 can be quickly installed and removed.
[0038] The specific distribution form of the arc-shaped damping portion 2222 and the limiting protrusion 2224 can be flexibly set. In one embodiment, the arc-shaped damping portion 2222 and the limiting protrusion 2224 of each rotating shaft 222 are distributed on the circumferential surface of the rotating shaft 222 in a radially opposite manner. In other words, the two are designed to be located in the diameter direction of the rotating shaft 222 and are arranged oppositely. This structure is easy to process and manufacture, thereby reducing production costs.
[0039] The degree of interference (friction) between the arc-shaped damping portion 2222 and the inner wall of the shaft hole 122, that is, the amount of interference fit, can be set according to different users. Preferably, in one embodiment, the amount of interference fit between the arc-shaped damping portion 2222 of each rotating shaft 222 and the inner wall of the shaft hole 122 can be 0.1-0.3 mm. In a preferred embodiment, it can be set to 0.2 mm.
[0040] According to another embodiment, the handle 20 further comprises a gripping arm 24 connecting the two pivot arms 22. The gripping arm 24 and the two pivot arms 22 are connected to each other to form a complete handle 20, and the user grasps the gripping arm 24 to lift and move the humidifier.
[0041] Optionally, the notch 1224 of each of the shaft holes 122 forms an acute angle, such as 45 degrees, with the top surface of the side wall 12 along the radially outward extending direction of the shaft hole 122. This acute angle setting is more ergonomic, so that when the user inserts the handle 20 into the appropriate part of the box body 10, the handle 20 can be inserted into the box body 10 without rotating it too much, thus saving time and effort.
[0042] In one embodiment, the limiting protrusion 2224 of each rotating shaft 222 extends along the length direction of the corresponding pivot arm 22. In this way, a longer limited space can be formed between the limiting protrusion 2224 and the corresponding pivot arm 22, so that the side wall 12 of the box body 10 can be more stably limited in the limited space to prevent the handle 20 from falling off the box body 10.
[0043] Furthermore, a stopper 124 is provided at one end of each side wall 12 close to the corresponding pivot arm 22 for preventing the pivot arm 22 from excessively rotating. The stopper 124 is provided so that when the pivot arm 22 further rotates in the direction of the stopper 124, it is blocked by the stopper 124, thereby preventing the pivot arm 22 from further rotating in the direction, which can ensure that the handle 20 is always within a specific angle rotation range.
[0044] Further preferably, each of the side walls 12 is provided with a protruding stand 126 corresponding to the stopper 124 at one end close to the corresponding pivot arm 22, which is configured to place the corresponding pivot arm 22 thereon. This makes it convenient for the user to store the handle 20 in the box body 10, so that when the humidifier is not in use, the space occupied by the entire humidifier can be reduced, making the overall structure of the humidifier more compact and beautiful.
[0045] Those skilled in the art will appreciate that the various operations, methods, steps, measures, and schemes in the processes discussed in this application may be alternated, altered, combined, or deleted. Further, other steps, measures, and schemes in the various operations, methods, and processes discussed in this application may also be alternated, altered, rearranged, decomposed, combined, or deleted. Further, the steps, measures, and schemes in the prior art that are similar to those disclosed in this application may also be alternated, altered, rearranged, decomposed, combined, or deleted.
[0046] The above description is only a partial implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
