Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a shell, a humidifier, and a molding die. Background Technology

[0002] A humidifier is an appliance that atomizes water into extremely fine water molecules and releases them into the air, thereby increasing the humidity of the environment. Therefore, its casing needs to have a water storage chamber with an opening at the top. In order to ensure the stability of the humidifier, its casing structure is usually smaller at the top and larger at the bottom. However, the internal cavity structure with a smaller top and larger bottom cannot be directly molded by drawing the core.

[0003] Therefore, in existing technologies, the shell is typically designed with an outer wall and an inner wall. The inner wall forms a water storage cavity that is open at the top and wider at the bottom, while the outer wall and inner wall form a cavity that is open at the bottom and wider at the top, allowing for direct core-pulling molding. Alternatively, the shell can be divided into two parts: an inner shell forming a water storage cavity that is open at the top and wider at the bottom, and an outer shell forming a hollow cavity that is wider at the bottom and narrower at the top. The inner and outer shells are then assembled and bonded together.

[0004] The shells formed by the above two methods have the following disadvantages: they both have two layers of wall thickness, resulting in higher material and injection molding costs; and for the same external dimensions, their internal water storage chambers are smaller. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a shell, a humidifier, and a molding die to solve the above problems.

[0006] The present invention adopts the following solution:

[0007] This application provides a housing, which is integrally formed, including a first cavity having a smaller upper part and a larger lower part with an upper opening; a second cavity formed by sinking down along the bottom plane of the first cavity; a mounting cavity with a lower opening for mounting electronic components is formed between the side wall of the second cavity and the downwardly extending side wall of the first cavity; an air passage with its bottom communicating with the mounting cavity is provided along the side wall of the first cavity, and an air outlet is provided on the upper side of the air passage.

[0008] Furthermore, the bottom surface of the second cavity is provided with a recessed mounting hole for mounting a vibration device.

[0009] Furthermore, a limiting step is provided on the inner wall of the top of the first cavity.

[0010] This utility model also provides a humidifier, including the aforementioned housing.

[0011] This utility model also provides a molding die for molding the shell, including a first core and a plurality of second cores surrounding the first core; the first core and the second cores together mold the first cavity and the second cavity; the structure in which the air passage is placed in the cavity is molded by one of the second cores; after the first core moves, the plurality of second cores retract inward so that they can be normally pulled out from the upper opening.

[0012] Furthermore, the first core puller is generally cone-shaped, wider at the top and narrower at the bottom, and its side is provided with multiple sliding grooves that are adapted to the second core puller, so that the second core puller can slide along the sliding grooves and retract inward after the first core puller moves.

[0013] Furthermore, there are an even number of second core pullers, with two sets of second core pullers arranged at intervals retracting inwards sequentially.

[0014] Furthermore, a set of the grooves arranged at intervals has a large inclination, so that the second core puller placed on the groove first retracts inward.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] This utility model provides a housing with a first cavity that is smaller at the top and larger at the bottom with an opening at the top; a second cavity is formed by sinking down along the bottom plane of the first cavity; the cavity is formed by only one layer of wall thickness, which greatly reduces the amount of material used in the product due to its simple structure, saving material costs and injection molding costs; at the same time, the sinking second cavity allows the housing to have a larger water storage space, and the side wall of the second cavity is formed between the side wall of the second cavity and the downwardly extending side wall of the first cavity for installing electronic components, which makes better use of the limited space for the installation of components, making the entire housing structure more compact.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example

[0029] Combination Figures 1 to 5As shown, this embodiment provides a housing, which is integrally formed, including a first cavity 1 with a smaller upper part and a larger lower part and an upper opening; a second cavity 2 is formed by sinking down along the bottom plane of the first cavity 1; a mounting cavity 3 with a lower opening for mounting electronic components is formed between the side wall of the second cavity 2 and the downwardly extending side wall of the first cavity 1; an air passage 4 is provided along the side wall of the first cavity 1, the bottom of which communicates with the mounting cavity 3, and an air outlet 11 is provided on the upper side of the air passage 4.

[0030] Specifically, the housing 7 has a first cavity 1 with an upper opening for water storage. The first cavity 1 is shaped with a smaller top and a larger bottom to ensure stable placement on a flat surface after being filled with water. The bottom wall of the first cavity 1 is a horizontal stepped surface, which slopes down to form a second cavity 2. A mounting cavity 3 with a lower opening for installing electronic components is formed between the side wall of the second cavity 2 and the downward-extending side wall of the first cavity 1. This not only increases the water storage space but also makes full use of the limited space for the arrangement and installation of electronic components, making the entire housing 7 structure more compact. Inside the first cavity 1, the side wall of the first cavity 1 is used to form an air passage 4, and an air outlet 11 is provided on the upper side of the air passage 4 for gas to be blown out. The housing 7 has only one layer of wall thickness, greatly reducing the use of product materials and saving material and injection molding costs.

[0031] In this embodiment, a longitudinal slot is provided on the side wall of the first cavity 1, and a transparent element is sealed on the slot to form a transparent window 5 for easy observation of the water level. A recessed mounting hole 12 is provided on the bottom surface of the second cavity 2 for installing a vibration device to disperse the water in the cavity into a fine mist. A limiting step is provided on the inner wall of the top of the first cavity 1 to facilitate the installation of a top cover with a mist outlet.

[0032] This utility model also provides a humidifier, including the aforementioned housing 7, which has a larger water storage space, and after being filled with water, it enables the humidifier to have better stability on the table surface.

[0033] This utility model also provides a molding die for molding the aforementioned shell 7, such as... Figures 6 to 8As shown, the molding die includes a first core puller 8 and a plurality of second core pullers 9 surrounding the first core puller 8; the first core puller 8 and the second core pullers 9 together form the first cavity 1 and the second cavity 2; the structure of the air passage 4 placed in the cavity is formed by one of the second core pullers 9; that is, after the first core puller 8 and the plurality of second core pullers 9 are closed, they have an outer surface with the same shape as the interior of the cavity of the housing 7. One of the second core pullers is provided with a cavity for forming the air passage, the cavity being concave radially inward and forming a certain inclination angle in the vertical direction, so that the cavity is larger at the bottom and smaller at the top, so that the second core puller can be smoothly pulled out.

[0034] Because the first cavity 1 is shaped like a cone with a smaller top and a larger bottom, the first core puller 8 and the second core puller 9 cannot be pulled out simultaneously in one go due to the inverted design. Therefore, the first core puller 8 is generally cone-shaped with a larger top and a smaller bottom. In this embodiment, taking eight second core pullers 9 as an example, the side of the first core puller 8 is provided with four first sliding grooves 10 with a large inclination, each of which is used to install one second core puller 9; the second core pullers installed in the first sliding grooves 10 form second sliding grooves with a smaller inclination between them, which are used to install the remaining four second core pullers 9. Because the first sliding grooves 10 have a large inclination, when the first core puller 8 is pulled outward, the second core puller 9 placed on the first sliding groove 10 first retracts inward; then the second sliding groove placed in the second sliding groove retracts inward, so that the second core puller 9 avoids the inverted design and can be pulled out normally from the upper opening of the first cavity 1.

[0035] Of course, it should be noted that the molding die also includes a moving die and / or a fixed die for molding the outer side of the housing 7 to mold the mounting cavity 3 at the bottom of the housing 7. This part is prior art and will not be described in detail here.

[0036] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
