[0022] The following diagrams illustrate various embodiments of the present invention. For clarity, many practical details will be included in the following description. However, it should be understood that these practical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not essential. Furthermore, to simplify the drawings, some commonly used structures and components are depicted in simplified schematic form.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0025] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0026] like Figures 1 to 6As shown, the utility model discloses a hot air device for a bottle washing machine, comprising a machine body 1 and a hot air device, wherein the hot air device is fixed in the machine body 1 and comprises a fan 2, a heating element 3, and an air duct 4, wherein the fan 2 is arranged above the heating element 3. The air duct 4 is provided with an air inlet 41 and an air outlet 42, a left air duct 43, a connecting portion 44, and a right air duct 45, and the air duct 4 is in an N-shape. The connecting portion 44 is located above the left air duct 43 and the right air duct 45, and connects the left air duct 43 and the right air duct 45. The air inlet 42 is provided in the left air duct 43 and is located below and to the left of the connecting portion 44. The air outlet 42, the fan 2, and the heating element 3 are provided in the right air duct 45. Compared with the prior art, when the bottle washing machine is splashed with water, the present invention has the advantage of greatly improving the safety and service life of the product because the air inlet 41 is arranged in the left air duct 43 and is located at the lower left of the connecting part 44. The water will only stay in the left air duct 43 and will not enter the right air duct 45. The fan 2 and the heating element 3 in the right air duct 45 will not be splashed with water and thus will not be damaged or even cause electric shock to the user.

[0027] Specifically, the side of the machine body 1 is provided with an opening 12, and the air inlet 41 is directly opposite the opening 12. This arrangement allows only a small amount of water to flow from the opening 12 into the air inlet 41 even when the bottle washer is exposed to water, effectively preventing a large amount of water from flowing from the opening 12 into the air inlet 41 and then into the left air duct 43. The air inlet 41 is located at the lowest end of the left air duct 43, which ensures that any water that has entered the left air duct 43 will also be discharged through the air inlet 41. The machine body 1 is provided with a cleaning chamber 11, which is covered by a lid. The air outlet 42 is connected to the cleaning chamber 11 and directly faces the cleaning chamber 11. The air outlet 42 is located at the lowest end of the right air duct 45, which prevents hot air from being trapped in the right air duct 45 and not being discharged into the cleaning chamber 11.

[0028] More specifically, if Figure 5 , Figure 6 As shown, the air inlet 41 is provided with a grille 46 and a filter 5 that is snap-fitted to the air inlet 41 and covers the air inlet 41. The grille 46 and filter 5 are in contact with each other. The filter 5 has two positioning pieces 51 at its upper end and a spring hook 52 at its lower end. Two positioning slots 6 are formed between the side of the housing 1 and the left air duct 43 to accommodate the positioning pieces 51. The left air duct 43 has a latching slot 47 that engages with the spring hook 52. During installation, the two positioning pieces 51 of the filter 5 are first inserted into the two positioning slots 6. Then, the spring hook 52 is pressed to snap into the latching slot 47 to install the filter 5. During removal, the filter 5 can be removed by simply pressing the spring hook 52 to disengage it from the latching slot 47. This provides the advantages of simple and convenient installation and removal.

[0029] In addition, a drainage hole 48 is provided at the bottom of the left air duct 43 , and the drainage hole 48 is connected to the card slot 47 . The provision of the drainage hole 48 can drain water in the left air duct 43 more quickly.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
