Description

Technical Field

[0001] The invention relates to a push switch, a plate mounting structure and steaming and baking equipment. Background Art

[0002] Some equipment has a working cavity, and the equipment processes items in the working cavity. Plates are fixed in the working cavity by bolts. After the working cavity has been used for a period of time, stains are generated on the plates. The plates need to be disassembled and assembled by screwing the bolts, which is inconvenient. In the prior art, the plates are usually not disassembled for cleaning, but hands are put into the working cavity to clean the stains. On the one hand, this method is difficult to clean, especially for equipment with a deep working cavity. On the other hand, there is a personal safety hazard when the operator forgets to turn off the power. In addition, incomplete cleaning poses a food safety hazard to equipment that processes food.

[0003] For example, a steam-bake combination oven has an inner chamber and a fan. The inner chamber forms a working chamber, and the fan is mounted on the inner chamber to circulate air in the working chamber for improved heating uniformity. A baffle (equivalent to the plate described above) is bolted into the inner chamber, separating the fan from the food storage area. The baffle is equipped with several ventilation holes. During use, grease and other grease from food can splash onto the baffle. To clean it, the user typically has to bend down and reach into the inner chamber to wipe the baffle, making cleaning difficult and incomplete. This can also pose a safety hazard if the user forgets to turn off the power. Summary of the Invention

[0096] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the following examples.

[0097] See also Figure 1-6 An embodiment of the present invention provides a push switch 400 for use in a working condition where locking and unlocking are achieved by pressing.

[0098] Push switch 400 includes a housing 1, a clip 2, and a latch 3. The housing 1 and clip 2 are capable of relative motion, defined as a first direction. In practical applications, the first direction can be horizontal, vertical, or another direction. The clip 2 and housing 1 are slidably connected in the first direction. The relative motion of the latch 3 and housing 1 drives the clip 2 relative to the housing 1. In actual use, relative motion between the clip 3 and housing 1 can be achieved by pressing the latch 3 and / or housing 1.

[0099] In the initial state, the clip 2 in its initial position is locked to the housing 1, and the latch 3 is unlocked from the clip 2, allowing the latch 3 to move freely relative to the housing 1. Thus, the component to which the latch 3 is fixed can move freely relative to the component to which the housing 1 is fixed. After the clip 2 is slid relative to the housing 1 to the locked position, the force causing the latch 3 and the housing 1 to move relative to each other is released, and the press switch 400 enters the locked state. In the locked state, the clip 2 is locked to the housing 1, and the latch 3 is locked to the clip 2, and the two can be engaged and fixed, thereby fixing the component to which the latch 3 is fixed and the component to which the housing 1 is fixed together. The clip 2 in its locked position is unlocked by sliding relative to the housing 1. After being unlocked, the clip 2 returns to its initial state, i.e., the latch 3 or the housing 1 is pressed to unlock the clip 2, and then the clip 2 returns to its initial state.

[0100] In this embodiment, the initial state and the locked state of the latch tongue 3 and the housing 1 are switched by pressing, that is, the component fixed with the latch tongue 3 and the component fixed with the housing 1 are disassembled and assembled by pressing, which is convenient to operate.

[0101] During application, the shell 1 can be fixed and the tongue 3 can be set on a component that requires greater disassembly and assembly. For example, for a device with a working chamber 101, a plate is provided in the working chamber 101. The shell 1 can be fixed on the side wall of the working chamber 101, and the tongue 3 can be fixed on the plate. The plate can be pressed to lock and unlock the tongue 3 and the snap-on component 2, so that the plate can be installed in the working chamber 101 or removed from the working chamber 101. The specific operation is as follows: in the initial state, by pressing the plate, a force is applied to the latch 3, and the latch 3 presses against the clip 2, causing the clip 2 to slide relative to the housing 1. After the clip 2 moves to the locked position, the plate is no longer pressed, and the press switch 400 is in the locked state, and the plate is installed on the working chamber 101. In the locked state, by pressing the plate, a force is applied to the latch 3, and the latch 3 drives the clip 2 to slide relative to the housing 1, thereby unlocking the clip 2 from the housing 1. After unlocking, the latch 3 is no longer pressed, and the clip 2 automatically returns to the initial position and is locked. The latch 3 and the clip 2 are unlocked, and the plate is removed from the working chamber 101. Therefore, when cleaning the plate, the user can press the plate to remove it and clean it separately. Both sides of the plate can be cleaned. After cleaning, the baffle 300 can be installed by pressing it again. The user operation is simple and safe.

[0102] The push switch 400 further includes a reset locking member 4. In the locked state, the reset locking member 4 locks the clip 2 on the housing 1. After the locked clip 2 is unlocked, the clip 2 is reset to its initial state under the action of the reset locking member 4. The reset locking member 4 can be configured to always exert a force to pull the clip 2 away from the housing 1. When the clip 2 reaches the locked position, the reset locking member 4 presses the clip 2 against the limiting surface of the housing 1, thereby locking the clip 2 on the housing 1. When the housing 1 or the latch 3 is pressed to cause the clip 2 to overcome the force of the reset locking member 4 and slide relative to the housing 1 and unlock, the clip 2 automatically resets under the action of the reset locking member 4.

[0103] The reset locking member 4 can be a component with elastic force, which is arranged between the shell 1 and the clip 2. As an alternative, the reset locking member 4 can be a component with magnetic force, which is arranged between the shell 1 and the clip 2 or in other positions that can provide a force that keeps the clip 2 away from the shell 1 at all times.

[0104] In this embodiment, the reset locking member 4 includes an elastic member 5, which can be a spring or a spring. The two ends of the elastic member 5 respectively abut against the clamping member 2 and the housing 1, and the elastic member 5 is located at the end of the clamping member 2 away from the latch 3. A positioning groove 6 for positioning the elastic member 5 is provided on the inner wall of the clamping member 2 and / or the housing 1. The positioning groove 6 can be a groove whose shape is adapted to the outer shape of the elastic member 5. The groove is generally recessed inward relative to the end face of the clamping member 2 or the wall surface of the housing 1. The elastic member 5 is inserted into the groove, and the inner wall of the groove plays a protective and / or guiding role for the elastic member 5. As an alternative, the positioning groove 6 can also be an annular groove, and the elastic member 5 is inserted or sleeved into the annular groove.

[0105] A first hole section 111 and a second hole section 112 are formed in the housing 1. The first hole section 111 is used to guide the clip 2, and the reset locking member 4 abuts against the end surface of the first hole section 111 at the end away from the second hole section 112. In a direction perpendicular to the first direction, the width of the second hole section 112 is greater than the width of the first hole section 111. The second hole section 112 is used to cooperate with the clip 2 to lock or unlock the tongue 3. That is, when the clip 2 slides from the initial position to the locked position, the second hole section 112 and the end of the clip 2 near the tongue 3 work together to secure the tongue 3.

[0106] The housing 1 includes a travel hole 12, which extends along a first direction. The clip 2 includes a limit block 21 that is slidably connected to the travel hole 12. During the sliding process of the clip 2, the limit block 21 slides in the travel hole 12. The travel hole 12 can be set at a position corresponding to the first hole section 111. The limit block 21 can be located at the end of the clip 2 away from the tongue 3. The limit block 21 can be a columnar structure protruding upward. In the initial state, the limit block 21 abuts against one end of the clip 2 under the action of the reset locking member 4, thereby locking the clip 2 on the housing 1. The limit block 21 and the reset locking member 4 are used to lock the clip 2 in the initial state, and the structure is compact; the travel hole 12 also has a guiding effect on the limit block 21, thereby improving the stability of the press switch 400.

[0107] A track 13 is provided within the housing 1. The track 13 is formed by recessing the surface of the housing 1 inward. A protective surface 14 is provided on one or both sides of the track 13 to guide the slider 22. In this embodiment, both sides of the track 13 have a protective surface 14 to guide the slider 22, thereby improving the stability of the slider 22.

[0108] The clamping member 2 includes a slider 22, and the track 13 serves as a guide for the slider 22. When the housing 1 or the latch 3 is pressed, the slider 22 slides within the track 13. The track 13 includes a first position 131 and a second position 132. In the initial state, the slider 22 is located in the first position 131, and the clamping member 2 is locked to the track 13. In the locked state, the slider 22 is locked in the second position 132. At this time, the reset locking member 4 applies a force to the slider 22 toward the side where the latch 3 is located, causing the slider 22 to abut against the track 13 and be locked. Pressing the latch 3 and overcoming the force of the reset locking member 4 allows the slider 22 to continue sliding along the track 13, thereby achieving unlocking. After unlocking, the slider 22 is reset to its initial position under the action of the reset locking member 4.

[0109] The shape of the track 13 may vary in different embodiments. The path that the slider 22 takes from the initial position to the locked position may be a straight line, a smooth curve, or a zigzag line. The path that the slider 22 takes from the locked position to the initial position after being unlocked may also be a straight line, a smooth curve, or a zigzag line. The track 13 may be a closed loop or linear. The track 13 may be unidirectional, with the slider 22 moving forward along the track but not in the reverse direction, or bidirectional, with the slider 22 moving forward along the track 13 and also moving in the reverse direction to the initial position during the reset process.

[0110] In this embodiment, the track 13 is a one-way closed track 13, that is, the track 13 is annular, and the slider 22 slides unidirectionally within the track 13. The track 13 includes a bent portion 133 corresponding to the locking position. A space is formed between the two side surfaces of the bent portion 133 for the slider 22 to slide. The first side 1331 of the bent portion 133 is recessed toward the first position 131, and the second side 1332 is preferably also recessed toward the first position 131. The first side 1331 and the second side 1332 form portions of the aforementioned protective surface 14, with the first side 1331 acting as the aforementioned limiting surface. When the slider 22 slides to the recessed position of the bent portion 133 and releases the pressure on the latch 3, the slider 22 abuts against the first side 1331 of the bent portion 133 under the action of the reset lock 4, thereby locking the clamping member 2 to the housing 1. When the latch 3 is further pressed and the force of the reset lock 4 is overcome, the slider 22 slides out of the bent portion 133 and is unlocked. In this embodiment, a bending portion 133 is provided on the rail 13 and the slider 22 is pressed against the bending portion 133 by the reset locking member 4 to lock the clamping member 2. This is simple to operate and facilitates assembly and disassembly of the component provided with the latch tongue 3.

[0111] The track 13 may be provided with a first limiting portion 134, so that when the slider 22 in the locked state slides along the track 13, the first limiting portion 134 is used to prevent the slider 22 from sliding in the reverse direction. In this embodiment, the first limiting portion 134 is provided on the bottom surface of the track 13 and is arranged in a stepped shape. In other embodiments, as an alternative, the first limiting portion 134 may be a raised structure provided on the side of the track 13. The raised structure has one surface that can guide the slider 22 to facilitate the forward movement of the slider 22 into the bent portion 133, and another surface that is perpendicular to the side of the track 13. When the slider 22 in the bent portion 133 moves in the reverse direction, this surface limits the slider 22, preventing the slider 22 from moving in the reverse direction.

[0112] In this embodiment, no second stop is provided on the track 13. However, in other embodiments, a second stop may be provided on the track 13 to prevent the slider 22 from sliding in the reverse direction after the slider 22 is unlocked from the locked state. The second stop can be provided on the side of the track 13, with a specific structure similar to the raised structure in the above embodiment. The second stop can also be provided on the bottom surface of the track 13 in a stepped shape.

[0113] In this embodiment, a third limiting portion 135 is further provided to prevent the slider 22 from sliding in the reverse direction when the slider 22 slides along the track 13 in the initial state. The third limiting portion 135 can be a step-shaped structure provided on the bottom surface of the track 13.

[0114] The track 13 also includes a first sliding portion 136. When the slider 22 is located at the first end of the first sliding portion 136, the clamping member 2 is in its initial position. The second end of the first sliding portion 136 is connected to one end of the bent portion 133. The first sliding portion 136 has a first step 1361 near the bent portion 133. The first step 1361 is used to prevent the slider 22 located at the bent portion 133 from sliding in the opposite direction. In a specific implementation, the first sliding portion 136 can be provided in two sections, with the bottom surface of one section being higher than the bottom surface of the other section, thereby forming the first step 1361 at the connection between the two sections. The bottom surface of the other section and the bottom surface of the bent portion 133 are located in the same plane. The first step 1361 also corresponds to the first stop 134 described above. During operation, the latch tongue 3 is pressed, and the latch tongue 3 drives the latching member 2, so that the slider 22 slides along the first sliding portion 136 to the bending portion 133. During the sliding process, the slider 22 falls at the step. When the latch tongue 3 is pressed to drive the slider 22 located at the bending portion 133 to slide, the first step 1361 limits the reverse movement of the slider 22.

[0115] The track 13 also includes a second sliding portion 137 connected to the other end of the bent portion 133. The slider 22, unlocked from the bent portion 133, passes through the second sliding portion 137 to reach its initial position and return to its original position. The first end of the second sliding portion 137 includes a sloped surface 1371, the lower end of which connects to the bottom surface of the bent portion 133. The slider 22 slides from the bent portion 133 toward the sloped surface 1371, smoothly transitioning into the second sliding portion 137. The second end of the second sliding portion 137 forms a second step 1372, which is used to prevent the slider 22 from moving backwards in the initial position and is equivalent to the third stopper 135 described above.

One end of the first inclined surface 311 extends to the end surface of the latch 3 near one end of the connecting member 2, and the other end connects to the side of the latch 3 via the second inclined surface 312. As the connecting member 2 slides from the initial position to the locked position, the claw 25 may first contact the first inclined surface 311, then gradually slide to the second inclined surface 312, and then secure the latch 3 at the second inclined surface 312. Alternatively, the claw 25 may directly contact the second inclined surface 312 and ultimately secure the latch 3.

[0121] The housing 1 includes a mounting hole 11 for the connector 2 to be inserted into. The mounting hole 11 includes the above-mentioned first hole section 111 and second hole section 112. The claw 25 includes a fixed end 252 and a free end 253. The fixed end 252 is fixed to the end of the connector block 23 near the latch 3, and the free end 253 protrudes from the connector block 23.
