[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0019] like Figure 1-10 As shown, a manual / automatic switching device with a waterproof outer casing includes: The housing assembly and the control module 1 housed within the housing assembly, the control module 1 being able to activate the alarm by automatic detection or manual triggering; The housing assembly includes at least a base 2 and a front cover 3 that engage with each other, with a cavity spaced between the base 2 and the front cover 3. The control module 1 is disposed in the cavity between the base 2 and the front cover 3, and the control part of the control module 1 extends out of the cavity, thereby exposing the operating area 3.1 on the front cover 3. The housing assembly also includes a protective shell 4 covering the operating area 3.1. The protective shell 4 is preferably fitted to the front end face of the front cover 3 to ensure protection of the operating area 3.1. A sliding track 5 is defined between the base 2 and the front cover 3. The protective shell 4 is constrained to move on the sliding track 5. The protective shell 4 has at least a static position that covers the operating area 3.1 and an open position that moves along the sliding track 5 and exposes the operating area 3.1.

[0020] In the static position, the protective shell 4 shields the operating area 3.1, effectively preventing accidental touch or interference from environmental factors on the operating panel, significantly improving the durability, ease of operation, and environmental adaptability of the device; With the protective shell 4 in the open position, the operating area 3.1 is exposed, ensuring that the daily protective performance is not affected while quickly switching between manual and automatic modes in an emergency. Furthermore, the sliding operation of the protective shell 4 is intuitive and efficient, meeting the emergency response requirements of fire-fighting equipment. The protective shell 4 is reusable, thus avoiding the drawbacks of traditional fragile panels that are only used once.

[0021] The sliding track 5 also constrains the front and rear positions of the protective shell 4, preventing the protective shell 4 from being pressed in a static position and triggering the control module 1.

[0022] As a further embodiment of the protective shell 4, the protective shell 4 surrounds the outside of the front cover 3 and exposes the front cover 3 at one end of the sliding track 5. The protective shell 4 further covers the joint between the front cover 3 and the base 2, at least covering the sliding track 5. Preferably, the protective shell 4 extends to the sides of the base 2 and the front cover 3, thereby providing reliable protection for the front cover 3 and the base 2.

[0023] like Figure 2 and Figure 3 As shown, preferably, the lower end of the protective shell 4 is open, making it difficult for dust and liquid to enter. In this case, the sliding track 5 is set vertically so that the protective shell 4 can move in the vertical direction. This method provides reliable protection for the front cover 3 and the base 2 while ensuring that the protective shell 4 can slide.

[0024] In other embodiments, the opening of the protective shell 4 may be in other directions, and of course, the sliding track 5 is also set in the same direction as the opening of the protective shell 4.

[0025] To facilitate the operation of the protective shell 4, an operating protrusion 4.7 is also provided on the protective shell 4. The user can optimize the sliding operation of the protective shell 4 through the operating protrusion 4.7. The operating protrusion 4.7 is preferably located at the open position of the protective shell 4.

[0026] As a further explanation of the protective shell 4 and the sliding track 5, the base 2 or the front cover 3 is provided with grooves on both sides for forming the sliding track 5. The grooves can be formed on both sides of the base 2 or on both sides of the front cover 3. Of course, the grooves can also be formed on the base 2 and the front cover 3 respectively. The purpose is to form concave sliding tracks 5 on both sides of the shell assembly so that the protective shell 4 can be inserted into it and slide, thereby improving sliding stability.

[0027] In this embodiment, the channel is located on the side of the front cover 3, and the base 2 closes the channel.

[0028] from Figure 5 As can be seen, the protective shell 4 specifically includes a top protective wall 4.5 correspondingly disposed on the top of the front cover 3. The top protective wall 4.5 abuts against the top of the front shell to keep the protective shell 4 in a static position.

[0029] Specifically, the protective shell 4 includes a front protective wall 4.6 and side protective walls 4.4 connected to both sides of the front protective wall 4.6. The top protective wall 4.5 connects the front protective wall 4.6 and the side protective walls 4.4. The front protective wall 4.6 is set on the front end face of the front cover 3 and shields the operating area 3.1. The side protective walls 4.4 are set outside the sliding rail 5. The side protective walls 4.4 are provided with guide parts inserted into the sliding rail 5. The cooperation between the channel and the guide parts realizes the smooth sliding of the protective shell 4, reduces friction loss, and extends service life. The guide parts are inserted into the sliding rail 5, thereby restricting the movement of the protective shell 4 in the front-back direction.

[0030] Further reference Figure 9 and Figure 10 Furthermore, the sliding track 5 is provided with a positioning part, which cooperates with the guide part and keeps the protective shell 4 in the open position or static position. Specifically, the positioning part protrudes from the sliding track 5 and abuts against the guide part.

[0031] like Figure 5 and Figure 6As one embodiment of the cooperation between the positioning part and the guiding part, the positioning part includes a first positioning part 5.1, and the guiding part includes a first guiding part 4.1. The first guiding part 4.1 is disposed near the starting end of the sliding track 5. In the static position, the first positioning part 5.1 is located in the open track of the guiding part and prevents the guiding part from moving to the open position. Specifically, the first positioning part 5.1 is located on the upper part of the first guiding part 4.1. The first positioning part 5.1 is preferably close to the first guiding part 4.1 in the static position, the purpose of which is to maintain the static position and provide damping force for the sliding of the protective shell 4. This ensures that the protective shell 4 can only move when actively force is applied, to prevent the protective shell 4 from being accidentally slid.

[0032] like Figure 7 and Figure 8 As shown, in another embodiment of the cooperation between the positioning part and the guide part, the positioning part includes a second positioning part 5.2, and the guide part includes a second guide part 4.2. The second guide part 4.2 and the second positioning part 5.2 are disposed near the end of the sliding track 5. The second guide portion 4.2 is located above the first guide portion 4.1 and the first positioning portion 5.1. In the static position, the second guide portion 4.2 is located below the second positioning portion 5.2. During the sliding process of the protective shell 4 toward the open position, the second guide portion 4.2 abuts against the second positioning portion 5.2 and crosses the second positioning portion 5.2. In the open position, the second positioning portion 5.2 is supported at the bottom of the second guide portion 4.2 and keeps the protective shell 4 in the open position. At this time, the operating area 3.1 is exposed, and the top of the protective shell 4 and the top of the front cover 3 are spaced apart to allow the protective shell 4 to slide downward.

[0033] In other embodiments, the number of guide portions may also be one, which interacts with the first positioning portion 5.1 and the second positioning portion 5.2 respectively.

[0034] Further reference Figure 8 As shown, as a further embodiment of the sliding track 5, the end of the sliding track 5 is provided with a limiting part 5.3, and the second guide part 4.2 abuts against the limiting part 5.3 and the second positioning part 5.2 in the open position. The space between the limiting part 5.3 and the second positioning part 5.2 on the sliding track 5 is matched with the length of the second guide part 4.2, thereby ensuring the stability of the second guide part 4.2 in the open position, preventing the protective shell 4 from sliding down, keeping the protective shell 4 in a fixed exposed state, and facilitating the operator to quickly trigger the manual alarm module 1.1.

[0035] Specifically, the positioning part is provided with a first guide surface 5.4 arranged along the direction of the sliding track 5, and the guide part is provided with a second guide surface 4.3 arranged towards the opening direction of the sliding track 5. The first positioning part 5.1 and the second positioning part 5.2 are both provided with arc-shaped first guide surfaces 5.4 about the direction of the sliding track 5. Preferably, the first guide surfaces 4.1 and the second guide surfaces 4.2 are both provided with inclined second guide surfaces 4.3 about the direction of the sliding track 5. Through the above improvements, the sliding resistance of the protective shell 4 is reduced and the smoothness of operation is improved while ensuring the stability of the protective shell 4 in the static position and the open position.

[0036] like Figure 4 As shown, as a further embodiment of the front cover 3 and the operating area 3.1, the front cover 3 has a convex side 4.8 on its front side. The front cover 3 forms a concave side inside the convex side 4.8. The operating area 3.1 is defined within the concave convex side 4.8. This method achieves a further separation between the protective shell 4 and the operating area 3.1, preventing accidental contact.

[0037] Specifically, the inner side of the protective shell 4 is provided with an inner convex side 3.2 that matches the outer convex side 4.8. The contours of the outer convex side 4.8 and the inner convex side 3.2 match, so as to improve the smoothness of the sliding of the protective shell 4 by matching the contours of the protective shell 4 and the front cover 3.

[0038] Furthermore, the inner convex side 3.2 and the outer convex side 4.8 are set at an angle to further optimize the guiding function of the protective shell 4.

[0039] Optionally, a switch direction indicator for the movement of the protective housing 4 in the static position and the open position is also provided on the outer surface of the protective housing 4.

[0040] During operation: In the static position, the protective shell 4 completely covers the operating area 3.1, the first guide part 4.1 abuts against the first positioning part 5.1 below, the guide surfaces of the two are closely attached to form a damping effect in the opening direction, and the second guide part 4.2 is located below the second positioning part 5.2; During the movement toward the open position, the user pushes the operating protrusion 4.7 of the protective shell 4 upwards. The first guide part 4.1 slides along the guide surface of the first positioning part 5.1, and after overcoming the damping, it disengages from the lock. The protective shell 4 continues to move upwards, and the second guide part 4.2 contacts the second positioning part 5.2. Guided by the inclined surface, the second guide part 4.2 passes over the second positioning part 5.2, and the protective shell 4 reaches the fully open position. The second guide part 4.2 is blocked by the limiting part 5.3, and the second positioning part 5.2 supports the second guide part 4.2 from below, forming a stable clamping.

[0041] Specifically, the control module 1 includes a manual alarm module 1.1 and an automatic alarm module. The manual alarm module 1.1 is exposed in the open position of the protective shell 4. The automatic alarm module is set to output an alarm signal based on the ambient gas. The manual alarm module 1.1 is specifically a button located in the operating area 3.1. The manual alarm module 1.1 and the automatic alarm module are conventional technologies in this field and will not be described in detail here. It is worth mentioning that the protective shell 4 surrounds the outside of the front cover 3 and the base 2 and is open at the bottom to allow the automatic alarm module to receive environmental information. In case of fire emergency, the operator can slide the protective shell 4 to the open position with one hand to quickly trigger the manual alarm. The manual alarm module 1.1 is only activated when the protective shell 4 is open to avoid accidental activation. The automatic alarm module operates independently and is triggered by ambient gas detection. The dual mechanism improves the reliability of the alarm.

[0042] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
