[0038] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Figure numerals: push and block slider 1, push and block panel 2, gear position display panel 3, push and block gasket 4, rear cover 5, front cover 6, screen 7, electrode plate 8, circuit board 9, accommodating hole 11, accommodating hole 12, positioning hook 13, positioning hook 14, ball 15, ball 16, contact electrode 17, contact electrode 18, sliding column 21, sliding card plate 22, gasket sliding groove 41, concave and convex guide rail 42, front cover sliding groove 61, sliding positioning guide rail 62.

[0040] like Figures 1 to 4 The push switch structure shown in the figure includes a push panel 2, a push gasket 4 and a push slider 1. A sliding column 21 is arranged on one side of the push panel 2. A gasket sliding groove 41 capable of accommodating the sliding of the sliding column is provided on the push gasket 4. The sliding column 21 passes through the gasket sliding groove 41 and is connected to the push slider 1. The connection relationship between the sliding column 21 and the push slider 1 can be a sliding connection, a detachable connection or a fixed connection, as long as the synchronous movement between the sliding column 21 and the push slider 1 can be achieved. The main technical problem to be solved is to prevent the relative movement between the sliding column 21 and the push slider 1.

[0041] On one side of the push-stop gasket 4 facing the push-stop slider, there are concave-convex guide rails 42. On both axial sides of the push-stop slider 1, there are receiving holes. A spring ball structure is installed in the receiving holes. One end of the spring ball structure abuts against the receiving holes 11 and 12, and the other end abuts against the concave-convex guide rails 42. When the push-stop panel 2 moves, the sliding column 21 of the push-stop panel 2 drives the push-stop slider 1 to move synchronously. The balls 15 and 16 in the spring ball structure move reciprocally on the surface of the concave-convex guide rails along the axial direction of the spring (not shown in the figure) under the drive of the push-stop slider. Since the surface of the concave-convex guide rails 42 has undulations, the movement trajectories of the balls in the spring ball structure will also fluctuate up and down with the surface shape of the concave-convex guide rails, specifically showing a movement form of peak-valley-peak-valley. When the balls are stuck in the valley between two peaks during the movement, they will stop, and the push-stop panel 2 moving synchronously with the push-stop slider 1 is fixed at a gear position, realizing the function of a multi-gear control switch. Preferably, a gear display board 3 is fixedly connected to one side of the push-stop slider. Multiple different gears can be set according to the requirements of different working conditions and application scenarios, such as: on gear, off gear, temperature control gear, gear 0, gear 1, gear 2, and so on. The push-stop slider 1 is in the shape of a "king". The receiving holes 11 and 12 are axially distributed on both sides of the push-stop slider 1, that is, at both ends of the middle horizontal bar of the push-stop slider 1 in the shape of a "king". On one side of the push-stop slider 1, positioning hooks 13 and 14 are installed. The positioning hooks 13 and 14 are fixedly connected to the gear display board 3. The function of the positioning hooks is to realize its synchronous movement with the push-stop slider 1 by fixedly connecting the gear display board 3, so that the gear numbers in the gear display board 3 are displayed on the screen 7 of the front cover of the electric heating controller.

[0042] As Figures 5 to 18 shown in the single push-stop switch electric heating controller, the push-stop switch structure of the above embodiment is provided in the electric heating controller. The electric heating controller includes a housing composed of a front cover 6 and a rear cover 5. The function of the rear cover 5 is to provide support and packaging. The front cover 6 is slidably connected to the push-stop switch structure and is used to realize the push-stop control of the electric heating controller through the push-stop switch structure. A front cover sliding groove 61 is opened on the front cover 6. The front cover sliding groove 61 and the gasket sliding groove 41 are on the same axis. A push-stop panel 2 is slidably arranged on the front side of the front cover 6. The push-stop panel 2 is slidably arranged in the recessed area on the front side of the front cover 6 and can slide along the axial direction of the front cover. The sliding column of the push-stop panel 2 passes through the front cover sliding groove 61 and the gasket sliding groove 41 and is fixedly connected to the push-stop slider 1 to realize the push-stop operation of controlling the push-stop slider 1 through the push-stop panel 2.

[0043] As a further improvement of the technical solution of this embodiment, a sliding clamping piece 22 corresponding to the sliding positioning guide rail 62 is installed on the push-stop panel 2. The sliding clamping piece 22 can slide axially in the sliding positioning guide rail 62 and is used to accurately position the movement trajectory of the push-stop panel 2.

[0044] The principle of realizing switch control of the push-block slider 1 through electrical connection with the circuit board through the contact electrodes 17, 18 is as follows: the contact electrodes 17, 18 are installed on the side of the push-block slider 1 facing the push-block panel 2, and a card interface for fixing the sliding column is arranged on this surface, and a contact electrode is arranged on the side of the push-block slider facing away from the push-block panel. The contact electrodes 17, 18 are in an "M" shape, and the contact electrodes have two contacts and two card-connecting ends. The two contacts are the two ends on the upper side of the M shape, and the card-connecting ends are the two ends under the M shape. The card-connecting ends are used to realize a card-connected connection relationship with the push-block slider 1, so that the contact electrodes 17, 18 are fixed on the push-block slider 1. The two contacts of the contact electrodes 17 and 18 face the circuit board, and an electrode plate 8 is arranged between the two contacts and the circuit board. A metal pole piece is installed on the electrode plate 8. The metal pole piece can form an electrical connection relationship with the contact electrodes 17 and 18, and also have an electrical connection relationship with the circuit board 9. When the push-block slider 1 moves along the axial direction of the electric heating controller under the control of the push-block panel 2, the contact electrodes 17 and 18 form different circuit connection relationships with the metal pole piece on the electrode plate 8 during movement, thereby realizing different gear functions.

[0045] like Figures 19 to 22 The double push switch electric heating controller shown in the figure has two push switch structures installed on the front cover of the double push switch electric heating controller. The difference between this embodiment and other embodiments is that there are two push switch structures, which are the same as the push switch structures used in other embodiments of the present application, but the number is increased.
